Plus or minus signs indicate presence of each condition (e.g., T+P+D– indicates participants who were trauma exposed, met criteria for lifetime PTSD, and did not have probable depression). Kruskal-Wallis tests were used to compare means of continuous variables across groups and χ2 tests for categorical variables.
BMI, body mass index; D, depression; LTL, leukocyte telomere length; P, posttraumatic stress disorder; PTSD, posttraumatic stress disorder; T, trauma.
