Objective
Metabolic syndrome is associated with elevated risk for cardiovascular disease and diabetes, and has increased prevalence in low-income African-Americans, which constitutes a significant health disparity. The mechanisms responsible for this disparity remain unclear; the current study investigated the relationship between Posttraumatic Stress Disorder (PTSD) and metabolic syndrome.
Method
We assessed childhood and adult trauma history, Major Depressive Disorder (MDD), PTSD, and the components of metabolic syndrome in an urban population. We recruited 245 low socio-economic status (SES), primarily African American subjects from general medical clinics in an inner-city hospital.
Results
Trauma exposure was extremely prevalent, with 90.6% of subjects reporting at least one significant trauma, and 18.8% of subjects meeting criteria for a current PTSD. Metabolic syndrome was also prevalent in this population (33.2%), with significantly higher rates among patients with current PTSD (47.8%, p<.05). After controlling for demographics, smoking history, antipsychotic use, depression, and exercise, current PTSD remained the only significant predictor of metabolic syndrome (p=0.006).
Conclusions
PTSD is associated with increased rates of metabolic syndrome within a traumatized, impoverished urban population. Further studies should investigate if PTSD treatment may reduce the rates of metabolic syndrome, improve overall health outcomes, and decrease healthcare disparities in minority populations.
