Several cross-sectional studies, but no prospective studies, have reported an association between an abnormal lipid profile and posttraumatic stress disorder (PTSD). We hypothesized that an abnormal lipid profile might predict risk for developing PTSD. In this prospective study, we analyzed data from 237 antidepressant-naïve severely injured patients who participated in the Tachikawa Cohort of Motor Vehicle Accident Study. High-density lipoprotein cholesterol (HDL-C) levels at baseline were significantly lower in patients with PTSD than those without PTSD at 6 months after motor vehicle accident (MVA) and were inversely associated with risk for PTSD. In contrast, triglycerides (TG) at baseline were significantly higher in patients with PTSD than in those without PTSD at 6 months post-MVA and were positively associated with risk for PTSD. There was no clear association between low-density lipoprotein cholesterol or total cholesterol and risk for PTSD. In conclusion, low HDL-C and high TG may be risk factors for PTSD. Determining lipid profiles might help identify those at risk for PTSD after experiencing trauma.
