Abstract:

Rates of tobacco use, posttraumatic stress disorder (PTSD), and depression are higher for veterans compared to their civilian counterparts. Female veterans have high rates of tobacco use and mental health (MH) conditions; however, little is known about sex differences in the association of depression and PTSD symptoms with postdeployment tobacco use. Cross-sectional associations and binary logistic regression models were conducted using baseline interview data from the Survey of Experiences of Returning Veterans sample (850 recently returned veterans; 352 women; age mean [standard deviation, SD]? = 35.63 [8.94]; 71.2% white). Men were more likely to be tobacco users (39.8% vs. 23.6%; chi square? = 24.40; ? < 0.001) and had higher postdeployment PTSD symptoms (men mean [SD]? = 48.62 [17.93], women mean [SD]? = 45.95 [18.22], ? = -2.12, ? < 0.05), but had similar rates of depression compared to women. In binary logistic models, sex, depression, and PTSD symptoms showed significant main effects in the prediction of postdeployment tobacco use, over and above the effects of demographics, military variables, and alcohol use. Sex moderated the association between PTSD symptoms and tobacco use, such that PTSD symptoms predicted tobacco use for women, but not for men. Sex did not moderate the association between depression and tobacco use. Given the divergent predictors of postdeployment tobacco use for male and female veterans, there may be sex-specific barriers to tobacco-use cessation, including factors related to MH conditions such as PTSD. Further examination of sex differences can help to identify tailored intervention strategies.
