PTSD-positive subjects had increased body mass index (BMI) (p<0.05), high sensitivity C-reactive protein (p<0.05), glucose (p<0.01), insulin (p<0.01), homeostatic model assessment-estimated insulin resistance (HOMA-IR) (p<0.02), creatinine (p<0.01), pulse rate (p<0.01), hemoglobin (p<0.02), and hematocrit (p<0.03), compared to the PTSD-negative subjects (Table 1). The gene discussed is INS; the disease is post-traumatic stress disorder.
