Key clinical point: Clinically meaningful reductions in PTSD symptoms in veterans led to a lower risk of developing type 2 diabetes as measured by PTSD Checklist (PCL) scores.
Major finding: Patients with clinically meaningful decreases in PCL score had significantly lower risk of developing type 2 diabetes (hazard ratio, 0.50; 95% confidence interval, 0.27-0.90; P equals .02), and those results remained consistent after adjusting for age (HR, 0.45; 95% CI, 0.25-0.82; P equals .01), calculating the results using weighted data (HR, 0.51; 95% CI, 0.26-0.98; P equals .04), and factoring in hypertension, obesity, and hyperlipidemia (HR, 0.49; 95% CI, 0.26-0.95; P equals .03).
Study details: A retrospective study of 5,916 patients in the Veterans Health Affairs system between 2008 and 2012.
Disclosures: This study was funded in part by a grant from the National Heart, Lung, and Blood Institute. Four authors reported receiving one or more grants from the institute during the study period.
