Although breast cancer occurs less frequently in Black women, compared with White women, they have a much higher risk of dying from the disease.

In the United States, age-adjusted breast cancer mortality between 2014 and 2018 was approximately 40% higher among Black women than among non-Hispanic White women.

This mortality gap likely reflects the fact that Black women face substantial barriers to obtaining timely, high-quality medical care, compared with White women, lead author Ismail Jatoi, MD, PhD, University of Texas Health Science Center, San Antonio, and colleagues suggest in a recent opinion piece.

The article was published online  in The New England Journal of Medicine.

When the team examined the statistics for breast cancer mortality, they found a surprise: The mortality gap between races only dates back to 1980.

Prior to 1980, mortality from breast cancer among Black women was slightly lower than White women, Dr. Jatoi and colleagues point out.

That year was a turning point in breast cancer management, as in 1980, both mammography screening and adjuvant endocrine therapy became available.

This was also when the mortality gap between the races started to show up.

It was disparities in access to the two new interventions that precipitated the divergence, as the authors suggest. Why this occurred is fairly self-evident, they comment.

“Black women are more likely than White women to lack health insurance or to have inadequate coverage, which has limited their access to mammography screening and adversely affected therapeutic decisionmaking,” researchers point out.

Moreover, both mammography screening and endocrine therapy primarily benefit patients with hormone receptor (HR)-positive breast cancer, which is equally common in Black and White patients. However, Black women have a 65% higher rate of HR-negative cancers than White women – and HR-negative tumors are often detected during the interval between mammography screening exams as palpable cancers.

Black women also have an 81% higher rate of triple-negative breast cancer, so they have benefited less from mammography screening and adjuvant endocrine therapy, both of which favor the detection and treatment of HR-positive breast cancer, the authors emphasize.

Some have suggested that the excess HR-negative breast cancer in Black women might be explained by hereditary factors. Yet as Dr. Jatoi and colleagues point out, the incidence of HR-negative breast cancer has actually been falling across all races in the United States since 1992.

However, the declines have been slower among Black women, and reductions in its incidence have been smaller among White women living in less affluent regions of the United States compared with White women from more affluent regions.

These patterns suggest that social determinants of health influence not only access to and quality of health care but also the development of HR-negative breast cancers, as the authors observe.

“If all people with breast cancer benefited equally from effective medical interventions, racial differences in mortality for individual tumor subtypes would largely reflect differences in incidence,” Dr. Jatoi and colleagues continue.

Yet the statistics show that the substantial racial disparities in mortality for both HR-positive and HR-negative cancers between Black and White women cannot be explained by differences in the incidence of either tumor alone, they write.

For example, mortality for HR-positive breast cancer is 19% higher among Black women than among White women, yet the incidence of HR-positive breast cancer is 22% lower among Black women.

Similarly, mortality from HR-negative breast cancer is over twice as high among Black women as it is among White women – a substantially larger disparity, compared with the 65% relative difference in the incidence of HR-negative breast cancer between the two races.

“Universal health care coverage could reduce disparities in treatment for cancers of all subtypes, including triple-negative breast cancer,” Dr. Jatoi and colleagues emphasize.

“Ensuring universal access to high-quality medical care can substantially narrow the racial disparity in U.S. breast-cancer mortality,” they conclude. 

The authors have reported no relevant financial relationships.

When 29-year-old Sakeenah Fowler was pregnant with her first child, doctors kept a close watch. Ms. Fowler has lupus, high blood pressure, a history of blood clotting, and kidney problems that all could have endangered her or the health of her unborn baby.

She saw maternal-fetal specialists who could keep watch of her high-risk pregnancy, and she collected urine samples every 24 hours to make sure her kidneys were functioning properly from her home in Roebuck, S.C.

But the pregnancy ultimately proved uneventful; even her kidneys remained stable. So Ms. Fowler said she was shocked when her doctors ordered an emergency cesarean delivery after she had gone into active labor.

“I was already dilated all the way to 6 cm,” but the baby’s heart rate had decreased by a small amount, she says. “They thought it was best to just go ahead with a C-section.”

Ms. Fowler, who is Black, said she believes the surgical intervention was unnecessary and that she wasn’t given a chance to discuss her options for a vaginal childbirth.  

“They already had it in their minds that I wasn’t going to make it through the pregnancy without any issues; then when I did, it was like they wanted to find something that made me have to have a C-section,” Ms. Fowler said. “It was close to the holidays; everybody was ready to go home. It was just like I was pushed to do what they wanted me to do.”

Ms. Fowler’s sense of a lack of choice is important beyond the measure of patient experience. While cesarean deliveries can be a lifeline for mother and baby, they can put up massive roadblocks to maternal and infant health when not necessary.

“The risk of hemorrhage, infection – on average, all of these go up when you have surgery instead of a vaginal delivery,” says Kimberly B. Glazer, PhD, a perinatal epidemiologist at the Icahn School of Medicine at Mount Sinai, New York.

“Birth is one of the most salient experiences you can have. People want to feel like their values and preferences – whatever they may be – were honored and respected. Even if the delivery goes a different way than you wanted, feeling like your values were taken into account is very important.”

More than 1 million women undergo cesarean deliveries in the United States every year, composing over 31% of all births in 2020, according to the Centers for Disease Control and Prevention.

The World Health Organization, meanwhile, recommends a rate of cesarean delivery of no more than 15% per region. Whether or not all the U.S. procedures were medically warranted is unclear, however.

Black women have higher odds of undergoing a cesarean: 36% undergo surgical deliveries annually, compared with about 30% of White women. Black women are also about three times more likely to die of pregnancy-related causes than White women.
 

Risk becomes reality

Ms. Fowler eventually developed an infection in her cesarean surgical wound, but her doctors initially insisted her alternating chills and fever were merely postpartum hormonal swings, she says.

“I thought something had to be wrong, but they just kept saying nothing was wrong,” she says.

By the time her doctors caught the infection, Ms. Fowler was readmitted to the hospital for several days of IV antibiotic therapy. The infection “almost got into my bloodstream and could have killed me,” she says.  

While cesarean deliveries are associated with decreases in maternal, neonatal, and infant mortality, the benefits are only seen up to a certain threshold. The WHO, for instance, has reported that over the 15% threshold, that lower mortality benefit disappears.

“When medically necessary, cesarean delivery can improve outcomes for mother and baby. But the fact that cesarean section rates have increased in recent years without a corresponding improvement in health outcomes indicates overreliance on the procedure,” Dr. Glazer says.
 

Clinical discretion leads to biased judgment calls

Rates of cesarean deliveries are even higher among low-risk pregnancies in women of color than in White women. Between 2016 and 2019, the overall rate of cesarean deliveries for low-risk births was 23%, according to a recent analysis. But the rate was almost 18% higher among Black women than among White women (27% vs. 22%).

“When you see data about these subjective indications varying by race and ethnicity, I think that’s pointing us toward some answers,” Dr. Glazer says. “Once you adjust for all these measures, prepregnancy characteristics, and risk factors, the research identifies variation in quality and outcomes that is rooted in structural and systemic racism in health care, implicit bias from clinicians.”

Researchers investigating cesarean deliveries have found that Black women are more likely to undergo the surgery for reasons that are highly subjective, such as fetal distress.

“There is a huge range of how concerning a fetal heart rate can be, and some health providers might perform a C-section for only minor changes in the fetal heart rate, while others might wait until it is much worse,” said Rebecca Hamm, MD, an assistant professor of obstetrics and gynecology at the Perelman School of Medicine at the University of Pennsylvania.

At least some of the differences in care can be explained by where women deliver their babies, studies have shown. Women of color disproportionately deliver at hospitals with poorer quality outcomes for moms and babies.
 

Dealing with the aftermath

There can be costs that reverberate throughout the life of a mother, child, and their family as the result of surgical delivery.

“Cesarean sections cost a lot more,” says Jamila Taylor, PhD, director of health care reform and a senior fellow with The Century Foundation, a progressive policy think tank in Washington, D.C. The cost of a cesarean delivery averages about $17,000, compared with about $12,200 for a vaginal birth; for uninsured patients, surgical deliveries cost about $9,000 more than vaginal deliveries.

Dr. Taylor, who has studied the historical mistreatment of Black women in obstetrics, noted that this cost includes not just the bill for surgery but also a prolonged recovery time that is often spent in a hospital bed.

Beyond the detrimental effect that a large hospital bill for delivery and aftercare can have on families, other costs can crop up later. Infants delivered by cesarean surgery are more likely to develop an infection, breathing problems, and to spend time in the neonatal intensive care unit than babies born vaginally. Although studies suggest these outcomes may result from a medically necessary health concern that spurred the cesarean surgery, they often stem from the delivery itself.  

Babies born surgically also miss out on the benefits of passing through the birth canal, such as supporting a newborn’s immune system and preparing their lungs to breathe oxygen after birth.

Most of the efforts to reduce inequities in maternal care are happening at the clinical level, aimed at both patients and providers, Dr. Taylor says.

“As advocates, we’re talking about how we can help Black women be advocates for themselves in the health care system – if the physician suggests a C-section, getting a second opinion, or walking through what a [surgical delivery] will mean and what their recovery will look like,” she says.

Women are also increasingly choosing non-hospital settings to deliver when possible, Dr. Taylor says. Including doulas or midwife practitioners in the maternal care team can reduce unnecessary cesarean deliveries among Black women, according to Camille Clare, MD, chair of the New York chapter of the American College of Obstetricians and Gynecologists.

Also, last year, race was removed from the vaginal birth after C-section (VBAC) calculator, which is used to gauge the safety of vaginal delivery in women with a history of surgical birth. The original calculator included race-based correction factors for Black women and Hispanic women. It predicted a lower likelihood of successful vaginal deliveries for women who already had a C-section and who identify as Black or Hispanic than for White women with otherwise identical characteristics, such as age, weight, and a history of cesarean delivery.

“Those are things that over time should reduce the high rates of cesarean section for Black women in particular,” Dr. Clare says.

In addition to embracing the updated calculator and including nurse-midwives and doulas in their obstetrics services, Penn Medicine, Philadelphia received a federal grant to study the impact of creating a standard plan for deliveries. This includes standardizing the induction of labor and any effect that might have on reducing C-section rates.

“This idea that biases lead to difference in decisionmaking, and that by standardizing practices we could address these differences – people were somewhat resistant at first,” Dr. Hamm says. “They didn’t believe there were differences in their practices.”

People struggle to recognize those differences, she says, and “it takes active participation in reducing disparities to make that happen.”

At the community level, Synergistic Sisters in Science (SIS), a group of maternal health experts and health equity advocates, is working on a project called PM3, to reduce maternal mortality through mobile technology.

The smartphone app will provide information for new moms to empower them to start conversations with health care providers. It also connects users to social support and resources. SIS is especially hoping to engage Black women living in rural areas.

“There is so much mistrust due to things like unnecessary C-sections and the fact that Black women feel they aren’t heard,” said Natalie Hernandez, PhD, executive director of the Center for Maternal Health Equity at Morehouse School of Medicine, Atlanta. “Here is a tool that gives a woman information that’s culturally centered, looks like her, and was informed by her voice.”

“Cesarean sections cost a lot more,” says Jamila Taylor, PhD, director of health care reform and a senior fellow with The Century Foundation, a progressive policy think tank in Washington, D.C. The cost of a cesarean delivery averages about $17,000, compared with about $12,200 for a vaginal birth; for uninsured patients, surgical deliveries cost about $9,000 more than vaginal deliveries.

Dr. Taylor, who has studied the historical mistreatment of Black women in obstetrics, noted that this cost includes not just the bill for surgery but also a prolonged recovery time that is often spent in a hospital bed.

Beyond the detrimental effect that a large hospital bill for delivery and aftercare can have on families, other costs can crop up later. Infants delivered by cesarean surgery are more likely to develop an infection, breathing problems, and to spend time in the neonatal intensive care unit than babies born vaginally. Although studies suggest these outcomes may result from a medically necessary health concern that spurred the cesarean surgery, they often stem from the delivery itself.  

Babies born surgically also miss out on the benefits of passing through the birth canal, such as supporting a newborn’s immune system and preparing their lungs to breathe oxygen after birth.

Most of the efforts to reduce inequities in maternal care are happening at the clinical level, aimed at both patients and providers, Dr. Taylor says.

“As advocates, we’re talking about how we can help Black women be advocates for themselves in the health care system – if the physician suggests a C-section, getting a second opinion, or walking through what a [surgical delivery] will mean and what their recovery will look like,” she says.

Women are also increasingly choosing non-hospital settings to deliver when possible, Dr. Taylor says. Including doulas or midwife practitioners in the maternal care team can reduce unnecessary cesarean deliveries among Black women, according to Camille Clare, MD, chair of the New York chapter of the American College of Obstetricians and Gynecologists.

Also, last year, race was removed from the vaginal birth after C-section (VBAC) calculator, which is used to gauge the safety of vaginal delivery in women with a history of surgical birth. The original calculator included race-based correction factors for Black women and Hispanic women. It predicted a lower likelihood of successful vaginal deliveries for women who already had a C-section and who identify as Black or Hispanic than for White women with otherwise identical characteristics, such as age, weight, and a history of cesarean delivery.

“Those are things that over time should reduce the high rates of cesarean section for Black women in particular,” Dr. Clare says.

In addition to embracing the updated calculator and including nurse-midwives and doulas in their obstetrics services, Penn Medicine, Philadelphia received a federal grant to study the impact of creating a standard plan for deliveries. This includes standardizing the induction of labor and any effect that might have on reducing C-section rates.

“This idea that biases lead to difference in decisionmaking, and that by standardizing practices we could address these differences – people were somewhat resistant at first,” Dr. Hamm says. “They didn’t believe there were differences in their practices.”

People struggle to recognize those differences, she says, and “it takes active participation in reducing disparities to make that happen.”

At the community level, Synergistic Sisters in Science (SIS), a group of maternal health experts and health equity advocates, is working on a project called PM3, to reduce maternal mortality through mobile technology.

The smartphone app will provide information for new moms to empower them to start conversations with health care providers. It also connects users to social support and resources. SIS is especially hoping to engage Black women living in rural areas.

“There is so much mistrust due to things like unnecessary C-sections and the fact that Black women feel they aren’t heard,” said Natalie Hernandez, PhD, executive director of the Center for Maternal Health Equity at Morehouse School of Medicine, Atlanta. “Here is a tool that gives a woman information that’s culturally centered, looks like her, and was informed by her voice.”

MADRID – During the International Scientific Symposium “New Frontiers in Scientific Research” that recently took place in Barcelona, specialists analyzed the role of the very-low-calorie ketogenic diet. This analysis was in relation to three comorbidities that have a higher incidence among overweight and obese patients: polycystic ovary syndrome, nonalcoholic fatty liver disease, and type 2 diabetes. The experts’ aim? To analyze and update the latest evidence on the benefits of this dietary choice.

Polycystic ovary syndrome

Alessandra Gambineri, MD, PhD, associate professor at the department of medicine and surgery (DIMEC) at the University of Bologna, Italy, addressed the link between obesity and polycystic ovary syndrome, which she described as a chronic disease that affects about 10% of women of childbearing age and that presents diverse phenotypes with different characteristics.

“The pathophysiology of this syndrome is characterized by the interaction of three factors: androgen excess, adipose tissue dysfunction, and insulin resistance. These factors interact with each other and are expressed differently in each phenotype,” said Dr. Gambineri.

She indicated that adipose tissue dysfunction is central to this pathology. This centrality results from its association with secretions, such as free fatty acids, proinflammatory cytokines, certain adipokines that promote insulin resistance, glucocorticosteroids, androgens, and oxidative stress.

“Similarly, the oxidative stress that characterizes this syndrome is increasingly present in obese individuals,” said Dr. Gambineri. “This oxidative stress also produces ovary hypotoxicity that aggravates ovulatory function. In this context, the very-low-calorie ketogenic diet can be useful in several ways: weight reduction; promoting the loss of mainly visceral/abdominal fat; decreasing lipotoxicity; and improving inflammation, hyperinsulinemia, and insulin resistance.”

This was the path followed to carry out a study that aimed to analyze the effects of the very-low-calorie ketogenic diet on manifestations of polycystic ovary syndrome in the obesity phenotype. Dr. Gambineri presented its results.

“The objective was to compare the effects of a very-low-calorie ketogenic diet and the standard low-calorie (hypocaloric) diet as a control group,” she said. “The effects studied include body weight, insulin resistance, menstrual cycle, ovulation, ovarian morphology, and hyperandrogenism in a population of 30 obese women with polycystic ovary syndrome and insulin resistance.”

Study participants had a diagnosis of polycystic ovary syndrome as defined by the National Institutes of Health criteria and were aged 18-45 years. These women were randomly assigned to two groups of equal size: experimental (very-low-calorie ketogenic diet) and control (hypocaloric diet). “The women assigned to the experimental group followed the ketogenic stage for eight weeks and then moved to the second, low-calorie diet phase for an additional eight weeks, while those in the control group (hypocaloric diet) followed the low-calorie diet for all 16 weeks.”

The primary outcomes were changes in weight and body composition, specifically fat mass and lean mass, measured by bioimpedance. “The changes observed in the following aspects were considered secondary outcomes: abdominal fat distribution, metabolic parameters, ovulation, ovarian morphology, hirsutism, hyperandrogenism, psychological well-being, and psychological distress,” said Dr. Gambineri. “Any reduction in the ovarian stroma, the area where androgens are synthesized, was also analyzed.”

The study authors found that although BMI decreased in both groups, this reduction was greater in the group that followed the very-low-calorie ketogenic diet. Significant weight loss was observed in both groups, 12.4 kg versus 4.7 kg. Significant differences were also observed in waist circumference (−8.1% in the experimental group vs. −2.2% in the control group), fat mass (−15.1% vs. −8.5%), and free testosterone (−30.3% vs. +10.6%). Only the experimental group saw a reduction in insulin.

“A key point regarding hyperandrogenism, especially regarding what’s referred to as free testosterone, there was only a significant reduction in the very-low-calorie ketogenic diet group,” said Dr. Gambineri. “This reduction was especially evident in the first part of the study, coinciding with the ketogenic period. The reason for this effect lies in the significant increase in the concentration of sex hormone-binding globulins, SHB6. Said globulins bind to the testosterone present in female blood, producing a reduction in free testosterone, a very important effect considering that this syndrome is an androgenic disorder. Furthermore, current treatments for polycystic ovary syndrome do not reduce free testosterone as much as this dietary approach does.”

For the specialist, among all these positive effects in these patients, perhaps most important is the notable improvement that occurs in ovulation. “At the beginning of the study, only 38.5% of the participants in the experimental group and 14.3% of those in the control group had ovulatory cycles. After the intervention, 84.6% managed to ovulate, compared to 35.7% who achieved this goal in the other group.”

Dr. Gambineri suggested that this method is “valid for reducing fat mass and rapidly improving hyperandrogenism and ovulatory dysfunction in women with obesity and polycystic ovary syndrome.”
 

Reversing type 2 diabetes?

Daniela Sofrà, MD, an endocrinologist specializing in diabetology at La Source Clinic, Lausanne, Switzerland, reviewed the current evidence on the role of the very-low-calorie ketogenic diet in the management of type 2 diabetes.

“It’s time to rethink diabetes treatment and focus efforts on managing obesity as an associated factor,” she said. “One of the hypotheses being examined in this regard is the twin cycle, which postulates that type 2 diabetes is the result of excess fat in the liver. This in turn is associated with insulin resistance with pancreas dysfunction.”

Dr. Sofrà added that there is a study documenting for the first time the reversibility of the morphology of the diabetic pancreas after caloric restriction with the very-low-calorie ketogenic diet. “The reason for this effect is the use of visceral and intrahepatic fat, which can lead to the remission of the clinical manifestation of type 2 diabetes, understanding as such the definition made by the American Diabetes Association: glycosylated hemoglobin < 6.5% without pharmacological therapy.”

Specifically, the results of this research showed that after following the very-low-calorie ketogenic diet and achieving a 15% weight loss (mean weight loss of the participants), liver glucose levels returned to normal levels within 7 days. Beta cell function returned to near normal within 8 weeks.

“Subsequent studies have shown the durability of remission of type 2 diabetes, thanks to the reactivation of the insulin-secreting function of beta cells that had become dedifferentiated in the face of chronic nutrient excess. Specifically, 6 out of 10 patients maintained glycosylated hemoglobin < 6% after 6 months without the need for pharmacological therapy,” Dr. Sofrà added.

Likewise, she highlighted that the probability of achieving remission is mainly determined by the duration of the disease. “The years with diabetes are one of the main predictors of the response that the patient will have with this dietary intervention. Studies have shown that remission is possible in patients with diabetes for less than 6 years, although there are other projects that indicate that it can be achieved with up to 10 years’ duration.”

Based on these data, Dr. Sofrà emphasized the pleiotropic effects of the very-low-calorie ketogenic diet on glycemic control, favoring the possible remission of diabetes or the reduction of drugs, as well as the reduction of the HOMA-IR index (insulin resistance) and waist circumference in people with type 2 diabetes.
 

Nonalcoholic fatty liver disease

The third comorbidity of obesity that may benefit from the very-low-calorie ketogenic diet is hepatic steatosis, or nonalcoholic fatty liver disease, said Hardy Walle, MD, an internal medicine specialist and director/founder of the Bodymed center, Kirkel, Germany, and one of the authors of this research.

“Recent research shows that ectopic fat and nonalcoholic fatty liver disease could be considered a cause, or at least one of the causes, of most of the diseases that affect the population as a consequence of overweight and obesity,” said Dr. Walle. “Some authors have stated that without fatty liver, there is no type 2 diabetes.”

Dr. Walle pointed out that between 30% and 40% of the adult population has nonalcoholic fatty liver disease, a percentage that increases considerably in people with obesity, reaching 70% prevalence and increasing, in the case of type 2 diabetes, to almost 90%. “Even normal weight does not rule out fatty liver; in fact, about 15% of people with nonalcoholic fatty liver disease are not overweight.”

In a setting where there are no approved drugs for the treatment of fatty liver (the current standard approach focuses on lifestyle interventions), a short-term hypocaloric diet (or liver fasting) is considered an effective method for management of this pathology. This principle was demonstrated by a study by the Saarland University, Saarbrücken, Germany, that Dr. Walle used to illustrate this statement.

“The participants (60 patients with hepatic steatosis) followed a hypocaloric diet (less than 1,000 kcal/day) for 14 days with a formula rich in protein and fiber specially developed for the treatment of nonalcoholic fatty liver disease. A fibroscan was then performed with controlled attenuation parameter measurement to quantify fatty liver disease. The results showed not only a significant improvement in nonalcoholic fatty liver disease parameters but also a marked improvement in all relevant metabolic parameters (serum lipids, liver enzymes),” explained Dr. Walle.

“This evidence leads us to affirm that the concept of hepatic fasting (by means of a hypocaloric diet) marks a point of reference for a future treatment approach for nonalcoholic fatty liver disease,” he concluded.

The study that Dr. Gambineri presented was carried out with the collaboration of the Pronokal Group (Nestlé Health Science). Dr. Gambineri, Dr. Sofrà, and Dr. Walle disclosed no relevant financial relationships.

Menopause gets a bad rap in medical literature and throughout society, say authors of a new analysis. And they argue that the negativity undermines women’s health outlook in the years that should be a natural life transition.

Menopause has been medicalized over centuries and talked about as if it were a disease, they say, and that may increase women’s anxiety and apprehension about the midlife stage.

It’s time to change the narrative, says Martha Hickey, MD, with the department of obstetrics and gynaecology at the Royal Women’s Hospital in Victoria, Australia, and her coauthors. Their analysis was published online in the BMJ.

“The message that menopause signals decay and decline, which can potentially be delayed or reversed by hormonal treatments, persists and is reinforced by the media, medical literature, and information for women, often driven by marketing interests,” they write.

Such messages may chip away at women’s confidence. Dr. Hickey and colleagues cite surveys in the United States and Ireland that found that most women (65%-77%) feel unprepared for menopause.

“Together with limited public discussion and education and shame attached to ageing in women, this may contribute to embarrassment and negative expectations about menopause,” the authors write.
 

The ‘untold misery of oestrogen-starved women’

These messages have deep roots. Take for instance, gynecologist Robert Wilson’s words in his 1966 book “Feminine Forever.” The authors note he recommended estrogen for all menopausal women “to treat their ‘serious, painful and often crippling disease’ and avoid the ‘untold misery of alcoholism, drug addiction, divorce, and broken

homes caused by these unstable, oestrogen-starved women.’ ”

Women experience menopause in very different ways. Experience with menopause also differs by country, the authors explain. “Women’s experience of menopause is also strongly influenced by social values around reproduction and ageing, with positive or negative ramifications,” they write.

“For example, women tend to have worse experiences of menopause in countries where their value is predicated on youth and reproductive capacity and ageing is associated with decline.”

The authors argue that the medicalization of menopause has condensed the wide range of women’s experiences at a typical age into “a narrowly defined disease requiring treatment.”
 

Promoting exercise, stopping smoking among positive messages

An editorial by Haitham Hamoda, MD, and Sara Moger, with the British Menopause Society, notes that more than 75% of women experiencing menopause report symptoms, and more than 25% describe severe symptoms.

The editorialists point out that the National Institute of Health and Care Excellence and others recommend an individualized approach to addressing menopause that includes a comprehensive approach – advice on exercise, weight management, stopping smoking, and reducing alcohol as well as options such as hormone therapy (HT).

The literature says the main indication for HT is for severe symptoms and not as a preventive measure. “Evidence does not support use of HT to reduce the risk of dementia,” they point out.

While some women may benefit from HT, that should not be explored to the exclusion of other avenues of help, Dr. Hickey and colleagues write. Risks must also be considered.
 

Menopause blamed in a difficult time of life

Jennifer Howell, MD, an obstetrician/gynecologist and certified menopause provider at Duke University in Durham, N.C., told this news organization that menopause is often blamed in a time of life when women naturally are experiencing an array of stressful and emotional changes.

It often coincides with children heading to college, navigating midlife challenges in marriage, helping aging parents, managing demanding careers, and health issues.

People want a reason for changes women experience, and too often the finger gets pointed at menopause, Dr. Howell said.

The message women hear has always been, “It’s got to be your hormones. And people want to hear that there’s a hormonal solution.”

Making menopause the target also has led to nonevidence-based “snake-oil” type remedies sold in unregulated powders, creams, and pellets, Dr. Howell noted.

Dr. Howell has treated thousands of menopausal women in her clinic and she says she spends a good deal of time with them explaining a holistic view of the process, much like what the authors describe, with lifestyle changes and treatment options.

Sometimes HT is the solution, Dr. Howell says, but “it’s become a crutch. Hormones are not a panacea.”

She is frustrated with the amount of disinformation circulating online. Groups like the North American Menopause Society put out reliable evidence-based information, but they compete “with a lot of nonsense,” she says.

The message that women should hear, she says is that “[menopause] is a natural part of aging and there may or may not be symptoms that come along with it. If there are, there are things we can do,” she says.

Menopause gets a bad rap in medical literature and throughout society, say authors of a new analysis. And they argue that the negativity undermines women’s health outlook in the years that should be a natural life transition.

Menopause has been medicalized over centuries and talked about as if it were a disease, they say, and that may increase women’s anxiety and apprehension about the midlife stage.

It’s time to change the narrative, says Martha Hickey, MD, with the department of obstetrics and gynaecology at the Royal Women’s Hospital in Victoria, Australia, and her coauthors. Their analysis was published online in the BMJ.

“The message that menopause signals decay and decline, which can potentially be delayed or reversed by hormonal treatments, persists and is reinforced by the media, medical literature, and information for women, often driven by marketing interests,” they write.

Such messages may chip away at women’s confidence. Dr. Hickey and colleagues cite surveys in the United States and Ireland that found that most women (65%-77%) feel unprepared for menopause.

“Together with limited public discussion and education and shame attached to ageing in women, this may contribute to embarrassment and negative expectations about menopause,” the authors write.
 

The ‘untold misery of oestrogen-starved women’

These messages have deep roots. Take for instance, gynecologist Robert Wilson’s words in his 1966 book “Feminine Forever.” The authors note he recommended estrogen for all menopausal women “to treat their ‘serious, painful and often crippling disease’ and avoid the ‘untold misery of alcoholism, drug addiction, divorce, and broken

Postpartum complications may go unrecognized in women who incur anal sphincter injuries during childbirth, a review of electronic medical records at one academic health system suggests.

In the first 3 months after delivery, few patients with an obstetric anal sphincter injury (OASI) had documented pelvic floor problems, compared with higher rates documented in medical literature, the researchers found.

“Lack of identified pelvic floor dysfunction in this population differs from the incidence in previously published data and may reflect lack of identification by obstetric providers,” the researchers reported. The findings “highlight a gap in health care that, when addressed, could significantly improve postpartum quality of life.”

The findings are scheduled to be presented at the annual scientific meeting of the American Urogynecologic Society and International Urogynecological Association.

Anal sphincter injuries occur in about 4.4% of vaginal deliveries and are the most common cause of anal incontinence in women of reproductive age.

For the new study, researchers reviewed records of 287 women who underwent a vaginal birth that resulted in an anal sphincter injury at five Ohio hospitals affiliated with Cleveland Clinic from 2013 to 2015.

Of those who met eligibility criteria, 209 (72.8%) were White, 262 (91.3%) were non-Hispanic, and 249 (86.8%) were aged 20-34 years. Most had an epidural (92%), did not require a blood transfusion (97.9%), did not develop a vaginal hematoma (98.9%), and did not have their injury repaired in an operating room (97.2%), the researchers reported.

Among pelvic floor disorders, urinary incontinence was not reported in 96% of patients, fecal incontinence was not reported in 97.1%, and pelvic organ prolapse was not reported in 99.3%. Most had no recorded complications from their lacerations (87.8%) or postpartum depression (92%), the researchers found.

However, a 2015 study found that, 12 weeks after delivery, women with OASIs commonly reported symptoms of incontinence, with 26% reporting urinary stress incontinence, 21.4% urinary urgency incontinence, 59% anal incontinence, and 15% fecal incontinence.

Depression was also seldom identified despite higher risk of mood disorders among women with OASI, the researchers found.

The team also examined interpregnancy intervals, defined as the time between a woman’s first vaginal delivery and conception of a subsequent pregnancy. Of 178 women for whom data were available, the median interval was 26.4 months (95% confidence interval, 23.7-29.9), similar to the median for births nationally.

Lead researcher Alexandra Nutaitis, DO, a resident in obstetrics and gynecology at Cleveland Clinic Akron General, said in an interview that it’s unclear whether physicians did not inquire about symptoms or didn’t record them. She noted that anal sphincter injuries are a “stigmatized topic.”
 

Not asked, not told

Carolyn Swenson, MD, an associate professor in urogynecology at the University of Utah, Salt Lake City, said physicians in the study may have relied on patients to bring up their symptoms rather than using questionnaires to screen for problems.

“What we know is that if you don’t ask women about pelvic floor disorders, they often don’t tell you that they are experiencing symptoms,” said Dr. Swenson, who was not involved in the new research.

Dr. Swenson called for validated questionnaires to assess pelvic floor symptoms in postpartum patients.

Regarding interpregnancy intervals, Dr. Nutaitis said she would be surprised if women who experienced an OASI didn’t delay having another child longer than women who did not undergo that physical and psychological trauma – but other factors such as societal pressures may override any reluctance to proceed with another pregnancy.

Dr. Swenson said it’s possible that a subgroup of women who have severe complications, such as those with a fourth-degree tear, might put off having another child. However, more research is needed to find out, she said.

Dr. Nutaitis and Dr. Swenson disclosed no relevant financial relationships.

A phase 3 trial has associated the neurokinin-3 (NK3)–receptor inhibitor fezolinetant, an oral therapy taken once daily, with substantial control over the symptoms of menopause, according to results of the randomized SKYLIGHT 2 trial.

The nonhormonal therapy has the potential to address an important unmet need, Genevieve Neal-Perry, MD, PhD, said at the annual meeting of the Endocrine Society.

The health risks of hormone therapy (HT) have “caused quite a few women to consider whether hormone replacement is right for them, and, in addition, there are other individuals who have hormone-responsive cancers or other disorders that might prohibit them [from using HT],” Dr. Neal-Perry said.

The NK3 receptor stimulates the thermoregulatory center in the hypothalamus. By blocking the NK3 receptor, vasodilation and other downstream effects are inhibited, explained Dr. Neal-Perry. She credited relatively recent advances in understanding the mechanisms of menopausal symptoms for identifying this and other potentially targetable mediators.

SKYLIGHT 2 trial: Two phases

In the double-blind multinational phase 3 SKYLIGHT 2 trial, 484 otherwise healthy symptomatic menopausal women were randomized to 30 mg of fezolinetant, 45 mg of fezolinetant, or placebo. The 120 participating centers were in North American and Europe.

In the first phase, safety and efficacy were evaluated over 12 weeks. In a second extension phase, placebo patients were rerandomized to one of the fezolinetant study doses. Those on active therapy remained in their assigned groups. All patients were then followed for an additional 40 weeks.

The coprimary endpoints were frequency and severity of moderate to severe vasomotor symptoms as reported by patients using an electronic diary. There were several secondary endpoints, including patient-reported outcomes regarding sleep quality.

As expected from other controlled trials, placebo patients achieved about a 40% reduction in moderate to severe vasomotor symptom frequency over the first 12 weeks. Relative to placebo, symptom frequency declined more quickly and steeply on fezolinetant. By week 12, both achieved reductions of about 60%. Statistical P values for the differences in the three arms were not provided, but Dr. Neal-Perry reported they were significant.

Vasomotor severity, like frequency, is reduced

The change in vasomotor severity, which subjects in the trial rated as better or worse, was also significant. The differences in the severity curves were less, but they separated in favor of the two active treatment arms by about 2 weeks, and the curves continued to show an advantage for fezolinetant over both the first 12 weeks and then the remaining 40 weeks.

Overall, the decline in vasomotor symptom frequency remained on a persistent downward slope on both doses of fezolinetant for the full 52 weeks of the study, so that the reduction at 52 weeks was on the order of 25% greater than that seen at 12 weeks.

At 52 weeks, “you can see that individuals on placebo who were crossed over to an active treatment had a significant reduction in their hot flashes and look very much like those who were randomized to fezolinetant at the beginning of the study,” said Dr. Neal-Perry, who is chair of the department of obstetrics and gynecology at the University of North Carolina at Chapel Hill.

Other outcomes also favored fezolinetant over placebo. For example, a reduction in sleep disturbance observed at 12 weeks was sustained over the full 52 weeks of the study. The reduction in sleep symptoms appeared to be slightly greater on the higher dose, but the benefit at 52 weeks among patients after the crossover was similar on either active arm.

No serious side effects identified

There were no serious drug-related treatment-emergent adverse events in any treatment group. One patient in the placebo arm (< 1%), two patients in the 30-mg fezolinetant arm (1.2%), and five patients in the 45-mg arm (3%) discontinued therapy for an adverse event considered to be treatment related.

“The most common side effect associated with fezolinetant was headache. There were no other side effects that led patients to pull out of the study,” Dr. Neal-Perry reported at the meeting, which was held in Atlanta and virtually.

According to Dr. Neal-Perry the vasomotor symptoms relative to menopause, which occur in almost all women, are moderate to severe in an estimated 35%-45%. Some groups, such as those with an elevated body mass index and African Americans, appear to be at even greater risk. Study enrollment was specifically designed to include these high-risk groups, but the subgroup efficacy data have not yet been analyzed.

Other drugs with a similar mechanism of action have not been brought forward because of concern about elevated liver enzymes, but Dr. Neal-Perry said that this does not appear to be an issue for fezolinetant, which was designed with greater specificity for the NK3 target than previous treatments.

If fezolinetant is approved, Dr. Neal-Perry expects this agent to fulfill an important unmet need because of the limitations of other nonhormonal solutions for control of menopause symptoms.

HT alternatives limited

For control of many menopause symptoms, particularly hot flashes, hormone therapy (HT) is the most efficacious, but Richard J. Santen, MD, emeritus professor and an endocrinologist at the University of Virginia, Charlottesville, agreed there is a need for alternatives.

In addition to those who have contraindications for HT, Dr. Santen said in an interview that this option is not acceptable to others “for a variety of reasons.” The problem is that the alternatives are limited.

“The SSRI agents and gabapentin are alternative nonhormonal agents, but they have side effects and are not as effective,” he said. Hot flashes “can be a major disruptor of quality of life,” so he is intrigued with the positive results achieved with fezolinetant.

“A new drug such as reported at the Endocrine Society meeting would be an important new addition to the armamentarium,” he said.

Dr. Neal-Perry reports no conflicts of interest.

For control of many menopause symptoms, particularly hot flashes, hormone therapy (HT) is the most efficacious, but Richard J. Santen, MD, emeritus professor and an endocrinologist at the University of Virginia, Charlottesville, agreed there is a need for alternatives.

In addition to those who have contraindications for HT, Dr. Santen said in an interview that this option is not acceptable to others “for a variety of reasons.” The problem is that the alternatives are limited.

“The SSRI agents and gabapentin are alternative nonhormonal agents, but they have side effects and are not as effective,” he said. Hot flashes “can be a major disruptor of quality of life,” so he is intrigued with the positive results achieved with fezolinetant.

“A new drug such as reported at the Endocrine Society meeting would be an important new addition to the armamentarium,” he said.

Dr. Neal-Perry reports no conflicts of interest.

A phase 3 trial has associated the neurokinin-3 (NK3)–receptor inhibitor fezolinetant, an oral therapy taken once daily, with substantial control over the symptoms of menopause, according to results of the randomized SKYLIGHT 2 trial.

The nonhormonal therapy has the potential to address an important unmet need, Genevieve Neal-Perry, MD, PhD, said at the annual meeting of the Endocrine Society.

The health risks of hormone therapy (HT) have “caused quite a few women to consider whether hormone replacement is right for them, and, in addition, there are other individuals who have hormone-responsive cancers or other disorders that might prohibit them [from using HT],” Dr. Neal-Perry said.

The NK3 receptor stimulates the thermoregulatory center in the hypothalamus. By blocking the NK3 receptor, vasodilation and other downstream effects are inhibited, explained Dr. Neal-Perry. She credited relatively recent advances in understanding the mechanisms of menopausal symptoms for identifying this and other potentially targetable mediators.

SKYLIGHT 2 trial: Two phases

In the double-blind multinational phase 3 SKYLIGHT 2 trial, 484 otherwise healthy symptomatic menopausal women were randomized to 30 mg of fezolinetant, 45 mg of fezolinetant, or placebo. The 120 participating centers were in North American and Europe.

In the first phase, safety and efficacy were evaluated over 12 weeks. In a second extension phase, placebo patients were rerandomized to one of the fezolinetant study doses. Those on active therapy remained in their assigned groups. All patients were then followed for an additional 40 weeks.

The coprimary endpoints were frequency and severity of moderate to severe vasomotor symptoms as reported by patients using an electronic diary. There were several secondary endpoints, including patient-reported outcomes regarding sleep quality.

As expected from other controlled trials, placebo patients achieved about a 40% reduction in moderate to severe vasomotor symptom frequency over the first 12 weeks. Relative to placebo, symptom frequency declined more quickly and steeply on fezolinetant. By week 12, both achieved reductions of about 60%. Statistical P values for the differences in the three arms were not provided, but Dr. Neal-Perry reported they were significant.

Vasomotor severity, like frequency, is reduced

The change in vasomotor severity, which subjects in the trial rated as better or worse, was also significant. The differences in the severity curves were less, but they separated in favor of the two active treatment arms by about 2 weeks, and the curves continued to show an advantage for fezolinetant over both the first 12 weeks and then the remaining 40 weeks.

Overall, the decline in vasomotor symptom frequency remained on a persistent downward slope on both doses of fezolinetant for the full 52 weeks of the study, so that the reduction at 52 weeks was on the order of 25% greater than that seen at 12 weeks.

At 52 weeks, “you can see that individuals on placebo who were crossed over to an active treatment had a significant reduction in their hot flashes and look very much like those who were randomized to fezolinetant at the beginning of the study,” said Dr. Neal-Perry, who is chair of the department of obstetrics and gynecology at the University of North Carolina at Chapel Hill.

Other outcomes also favored fezolinetant over placebo. For example, a reduction in sleep disturbance observed at 12 weeks was sustained over the full 52 weeks of the study. The reduction in sleep symptoms appeared to be slightly greater on the higher dose, but the benefit at 52 weeks among patients after the crossover was similar on either active arm.

No serious side effects identified

There were no serious drug-related treatment-emergent adverse events in any treatment group. One patient in the placebo arm (< 1%), two patients in the 30-mg fezolinetant arm (1.2%), and five patients in the 45-mg arm (3%) discontinued therapy for an adverse event considered to be treatment related.

“The most common side effect associated with fezolinetant was headache. There were no other side effects that led patients to pull out of the study,” Dr. Neal-Perry reported at the meeting, which was held in Atlanta and virtually.

According to Dr. Neal-Perry the vasomotor symptoms relative to menopause, which occur in almost all women, are moderate to severe in an estimated 35%-45%. Some groups, such as those with an elevated body mass index and African Americans, appear to be at even greater risk. Study enrollment was specifically designed to include these high-risk groups, but the subgroup efficacy data have not yet been analyzed.

Other drugs with a similar mechanism of action have not been brought forward because of concern about elevated liver enzymes, but Dr. Neal-Perry said that this does not appear to be an issue for fezolinetant, which was designed with greater specificity for the NK3 target than previous treatments.

If fezolinetant is approved, Dr. Neal-Perry expects this agent to fulfill an important unmet need because of the limitations of other nonhormonal solutions for control of menopause symptoms.

The number and rate of U.S. abortions increased between 2017 and 2020 after a 30-year decline, according to a new report from the Guttmacher Institute.

More than 930,000 abortions took place in the United States in 2020, up 8% from 862,000 abortions in 2017. About one in five pregnancies ended in abortion in 2020, the report said.

The Guttmacher Institute, a research organization that supports abortion rights, said the trend shows a rising need for abortion care as the Supreme Court is poised to overturn the Roe v. Wade decision in coming weeks.

National abortion numbers reached the lowest point in 2017 since the landmark 1973 ruling that legalized the procedure. In the years following the ruling, abortion numbers rose above 1.5 million annually throughout the 1980s and then began declining in the 1990s, though they remained above 1 million annually through the early 2010s.

The latest data show that the abortion rate increased from 13.5 abortions per 1,000 women between ages 15 and 44 in 2017 to 14.4 abortions per 1,000 women in 2020, marking a 7% increase.

Similarly, the abortion ratio – or the number of abortions per 100 pregnancies – increased from 18.4% in 2017 to 20.6% in 2020, marking a 12% increase.

The increase in abortions was accompanied by a 6% decline in births between 2017 and 2020, the Guttmacher Institute said.

“Because there were many more births (3.6 million) than abortions (930,000) in 2020, these patterns mean that fewer people were getting pregnant and, among those who did, a larger proportion chose to have an abortion,” the institute wrote.

Medication-related abortions accounted for 54% of U.S. abortions in 2020, according to the report, which was the first time they made up more than half of abortions.

The number of abortions increased in every region of the country between 2017 and 2020, the report shows. The increases were largest in the West (12%) and Midwest (10%), followed by 8% in the South and 2% in the Northeast.

In some states – Illinois, Mississippi, and Oklahoma – there were substantial increases in the number of abortions, the institute said. In others – such as Missouri, Oregon, and North Dakota – there were substantially fewer abortions in 2020, compared with 2017.

The COVID-19 pandemic may have led to a decline in some states. In New York, abortions increased 5% from 2017 to 2019 and then fell 6% between 2019 and 2020. About 10% of clinics in New York paused or stopped abortion care in 2020 when the pandemic started.

New laws likely affected the numbers as well. Texas had a 7% increase between 2017 and 2019, followed by a 2% decrease between 2019 and 2020, which overlapped with restrictions that deemed abortions “nonessential” health care at the beginning of the pandemic.

In contrast, some numbers may have increased because of expanded Medicaid funding. Illinois began allowing state Medicaid funds to pay for abortions in January 2018, and abortions increased 25% between 2017 and 2020.

In Missouri, abortions decreased substantially from 4,710 in 2017 to 170 in 2020, the report shows, but the number of Missouri residents who traveled to Illinois for abortions increased to more than 6,500.

Every 3 years, the Guttmacher Institute contacts U.S. facilities that provide abortions to collect information about services, including the total number of abortions. The most recent count was completed in May, representing 1,687 health care facilities that provided abortions in 2019 or 2020. A full summary of the data will be published later this year in a peer-reviewed journal article.

Following a diet rich in healthy plant-based products may lower one’s risk of breast cancer, but not if that diet happens to be high in unhealthy foods, researchers have found.

The study of more than 65,000 people showed that plant-based diets that were high in whole grains, fruits, and vegetables appear to be more protective against breast cancer than diets rich in processed plant-based products, such as juice and chips.

“Results suggest that the best plant-based diet for breast cancer prevention could be a healthy plant-based diet comprising fruit, vegetables, whole grains, nuts, and legumes,” said Sanam Shah, MBBS, FCPS, MPH, a doctoral candidate in epidemiology at Paris-Saclay University, who is the lead author of the new study. “In contrast, an unhealthy plant-based diet comprising higher intakes of primarily processed products of plant origin, such as refined grains, fruit juices, sweets, desserts, and potatoes, would be worse for breast cancer prevention.”

Dr. Shah’s group is presenting their research online at the annual meeting of the American Society for Nutrition.

Although the role of plant-based diets in cancer prevention has received extensive attention, Dr. Shah said few studies have assessed the influence of the quality of those diets on the risk of breast cancer.

Dr. Shah and colleagues conducted a prospective cohort study to investigate the link between healthy and unhealthy plant-based diets and breast cancer risk. Unlike other studies, the researchers also evaluated the effect of a gradual decrease in animal products in diets on health.

Dr. Shah’s group followed 65,574 postmenopausal women in France (mean age, 52.8 years) from 1993 to 2014. The researchers used self-reported food questionnaires to classify women into groups on the basis of adherence to a mostly plant or animal diet. Plant-based diets did not exclude meat but had more plant than animal products, Dr. Shah said. The researchers also grouped women on the basis of how healthy the plant-based diets were.

Over the 21-year study period, 3,968 women were diagnosed with breast cancer. Those who adhered to a more healthful plant-based diet had a 14% lower risk than average of developing breast cancer, while those who adhered to a less healthful plant-based diet had a 20% greater risk of developing the disease.

Nutritional quality varies greatly across plant-based foods. Quality plant-based diets should focus on variety to avoid nutritional deficiencies in iron, zinc, calcium, and vitamin B12, Dr. Shah said.

“The study by Shah and coworkers underscores the importance of considering more global aspects of the diet rather than single components when examining relationships between diet and health,” said Megan McCrory, PhD, research associate professor of nutrition at Boston University. “As the study illustrates, plant-based diets as a whole are not always healthy and may also contain less desirable nutrients and foods.”

Abstracts in the conference have been selected by a board of experts for presentation but have not yet been peer reviewed. All findings are to be regarded as preliminary until they are published in peer-reviewed articles. Dr. Shah and Dr. McCrory disclosed no relevant financial relationships.

Sleep time may be a modifiable risk factor for cancer, according to a recent study from Japan.

The findings reveal that sleeping 10-plus hours may increase a woman’s risk of getting cancer and both men and women’s risk of dying from cancer. 

The researchers say their findings may help refine sleep recommendations in Japan, which currently advise working, middle-aged adults to sleep “as long as they can.”

Based on the new findings, a sleep duration of 6-8 hours for men and 6-9 hours for women “may be the safest” regarding cancer incidence and mortality risk among Japanese adults, the authors conclude.

The findings were published online in the International Journal of Cancer. 

The literature on sleep time and cancer risk is mixed. A trio of meta-analyses conducted between 2016 and 2019 found that long sleep duration, but not short, was associated with a slightly elevated risk of all cancer mortality in Asians.

A separate meta-analysis conducted in 2018 found that both short and long sleep durations were not related to cancer incidence. But in the stratified analysis, shorter sleep time was associated with 36% increased cancer risk among Asians.

To investigate further, the researchers pooled data from six population-based cohorts that included 271,694 adults – 126,930 men and 144,764 women – with 40,751 total incident cancer cases and 18,323 total cancer deaths during a follow-up lasting about 5.9 million person-years.

In the multivariable analysis, longer sleep duration was not associated with total cancer incidence in men. In women, however, sleeping 10 or more hours vs. 7 was associated with a 19% increased risk of cancer.

In addition, sleeping 10 or more hours was associated with an increased risk of dying from cancer in women (hazard ratio, 1.44) and men (HR, 1.18).

Sleeping for 5 hours or fewer, compared with 7, was not associated with cancer incidence and mortality. However, among postmenopausal women, shorter sleep durations did increase the risk of dying from cancer (HR, 1.15).

The authors highlight several strengths of the analysis, including a large sample size as well as stratification of the results by body mass index and menopause status, which has rarely been done in previous studies.

Limitations include self-reported sleep durations and lack of data on sleep quality. The researchers note that the mechanism by which sleep time may influence cancer incidence and mortality is unclear but likely to be complex and cancer site specific.

It’s also possible that reverse causation could explain associations between sleep duration and cancer occurrence and mortality – with pain from cancer, for instance, impairing sleep duration and quality. However, the sensitivity analysis found no evidence of reverse causality or other confounding factors.

Based on these findings, the researchers say sleep duration “may be an important variable to include in cancer incidence and mortality risk prediction models.”

The study had no specific funding. The authors declared no relevant conflicts of interest.

Sleep time may be a modifiable risk factor for cancer, according to a recent study from Japan.

The findings reveal that sleeping 10-plus hours may increase a woman’s risk of getting cancer and both men and women’s risk of dying from cancer. 

The researchers say their findings may help refine sleep recommendations in Japan, which currently advise working, middle-aged adults to sleep “as long as they can.”

Based on the new findings, a sleep duration of 6-8 hours for men and 6-9 hours for women “may be the safest” regarding cancer incidence and mortality risk among Japanese adults, the authors conclude.

The findings were published online in the International Journal of Cancer. 

The literature on sleep time and cancer risk is mixed. A trio of meta-analyses conducted between 2016 and 2019 found that long sleep duration, but not short, was associated with a slightly elevated risk of all cancer mortality in Asians.

A separate meta-analysis conducted in 2018 found that both short and long sleep durations were not related to cancer incidence. But in the stratified analysis, shorter sleep time was associated with 36% increased cancer risk among Asians.

To investigate further, the researchers pooled data from six population-based cohorts that included 271,694 adults – 126,930 men and 144,764 women – with 40,751 total incident cancer cases and 18,323 total cancer deaths during a follow-up lasting about 5.9 million person-years.

In the multivariable analysis, longer sleep duration was not associated with total cancer incidence in men. In women, however, sleeping 10 or more hours vs. 7 was associated with a 19% increased risk of cancer.

In addition, sleeping 10 or more hours was associated with an increased risk of dying from cancer in women (hazard ratio, 1.44) and men (HR, 1.18).

Sleeping for 5 hours or fewer, compared with 7, was not associated with cancer incidence and mortality. However, among postmenopausal women, shorter sleep durations did increase the risk of dying from cancer (HR, 1.15).

The authors highlight several strengths of the analysis, including a large sample size as well as stratification of the results by body mass index and menopause status, which has rarely been done in previous studies.

Limitations include self-reported sleep durations and lack of data on sleep quality. The researchers note that the mechanism by which sleep time may influence cancer incidence and mortality is unclear but likely to be complex and cancer site specific.

It’s also possible that reverse causation could explain associations between sleep duration and cancer occurrence and mortality – with pain from cancer, for instance, impairing sleep duration and quality. However, the sensitivity analysis found no evidence of reverse causality or other confounding factors.

Based on these findings, the researchers say sleep duration “may be an important variable to include in cancer incidence and mortality risk prediction models.”

Exposure to per- and polyfluoroalkyl substances (PFAS) – a class of widely used synthetic chemicals dubbed “forever chemicals” – may be a modifiable risk factor for the development of hypertension.

In a large, prospective study, researchers found an association between higher blood levels of PFAS and increased risk of hypertension in middle-aged women. Women in the highest tertile of overall PFAS concentrations had a 71% increased risk of developing hypertension.

“Our findings suggest that long-term cumulative exposure, even before midlife, may increase the risk of high blood pressure, and therefore, the benefit of reducing the population exposure to PFAS and potential prevention of high blood pressure and other health conditions would be enormous,” Sung Kyun Park, ScD, MPH, University of Michigan School of Public Health, Ann Arbor, said in an interview.

The study was published online  in Hypertension.
 

Everywhere and forever

“PFAS are forever chemicals as well as everywhere chemicals,” Dr. Park noted.

Possible sources of PFAS exposure run the gamut from nonstick cookware, food wrappers, and waterproof fabrics to cosmetics and drinking water. They have been detected in the blood of most people and have been linked to a variety of health concerns.

“A few studies showed an association between PFAS and hypertension, but those were cross-sectional and examined prevalence of hypertension. It was unclear whether PFAS are associated with the development (incidence) of hypertension,” Dr. Park explained.

For their study, the researchers examined the association between serum concentrations of PFAS and risks of incident hypertension in 1,058 initially normotensive women participating in the Study of Women’s Health Across the Nation-Multi-Pollutant Study (SWAN-MPS). They were followed annually between 1999 and 2017.

During 11,722 person-years of follow-up, 470 of the women developed hypertension, at a rate of 40.1 cases per 1,000 person-years. Hypertension was defined as blood pressure of at least 140 mm Hg systolic or at least 90 mm Hg diastolic or receiving antihypertensive treatment.

Women in the highest tertile of baseline serum concentration of perfluorooctane sulfonate (PFOS) had a 42% higher risk of developing hypertension, compared with peers in the lowest tertile (adjusted hazard ratio, 1.42; 95% confidence interval, 1.19-1.68; P trend = .01).

Similar results were found for perfluorooctanoate (PFOA) and 2-N-ethyl-perfluorooctane sulfonamido acetate (EtFOSAA), with 47% (aHR, 1.47; 95% CI, 1.24-1.75; P trend = .01) and 42% (aHR, 1.42; 95% CI, 1.19-1.70; P trend = .01) higher risks of incident hypertension, comparing the highest to the lowest tertiles.

The risks persisted after adjusting for various factors, including race, study site, education, financial strain, smoking status, alcohol use, total calorie intake, and menopausal status.

In the PFAS “mixture” analysis, women in the highest tertile of overall PFAS concentrations were 71% more likely to develop hypertension during follow-up, compared with women in the lowest tertile (aHR, 1.71; 95% CI, 1.15-2.54; P trend = .008).

“These findings suggest that PFAS might be an underappreciated contributing factor to women’s cardiovascular disease risk,” the researchers write.

They caution that the study only included middle-aged women and that it is unclear whether the findings hold for middle-aged men.

“This is an important question, but the answer is that we do not know,” Dr. Park told this news organization.

“Women become more susceptible to metabolic changes and hypertension risk during the menopausal transition. Our findings suggest that PFAS may play a role in the development of hypertension in women during this critical life stage,” Dr. Park said.

The researchers say more research is needed to confirm and expand the findings and to find ways to reduce PFAS exposure.

“If confirmed in future studies, these findings suggest that understanding human exposure to PFAS and developing effective strategies to reduce PFAS exposure may help prevent the development of hypertension and thereby reduce the global burden of CVD,” the researchers write.
 

‘The more we learn, the worse it gets’

This is an “interesting” study and shows that “the more we learn about PFAS, the worse it seems to get,” Ankur Shah, MD, division of kidney disease and hypertension, Warren Alpert Medical School of Brown University, Providence, R.I., said in an interview.

“This multisite, multiracial and multiethnic, community-based longitudinal study establishes an association between PFAS and hypertension,” said Dr. Shah, who wasn’t involved in the study.

“This adds to a growing literature base of associations of PFAS with illnesses, including malignancy, thyroid disorders, diabetes, ulcerative colitis, hyperlipidemia, and pregnancy-induced hypertension,” he noted.

Dr. Shah also noted that the authors adjusted for race and ethnicity, study site, education, financial strain, smoking status, environmental tobacco smoke, alcohol consumption, total calorie intake, and menopausal status “and still found a strong association.”

“Still to be determined are both whether PFAS are the causative agent or if there is an unmeasured/unadjusted for entity which has resulted in both increased PFAS exposure and hypertension, as well as if PFAS are causative, if reduction in PFAS exposure would be result in blood pressure reduction,” Dr. Shah added.

The study had no sources of funding. Dr. Park and Dr. Shah have disclosed no relevant financial relationships.
