Abstract:
Smoking rates are higher in U.S. soldiers than civilians, with combat-experienced soldiers particularly at risk for heavy smoking (≥20 cigarettes/day). While heavy smoking is correlated with mental health symptoms in civilian samples, the extent to which these symptoms, background variables, and unit climate (self-reported assessments of cohesion, organizational support, and leadership) are linked to smoking in at-risk soldiers remains unclear. The present study examines a range of correlates of smoking-related behavior. Cross-sectional, anonymous surveys were collected from 3,380 soldiers following a deployment in 2008-2009. Measures included demographics, combat exposures, unit climate (e.g., unit cohesion, perceived organizational support, leadership), short sleep duration, and behavioral health variables (e.g., posttraumatic stress disorder, depression, anxiety, alcohol misuse, aggression, adverse childhood experiences [ACEs]). Logistic regression modeled the effects of these variables on two outcome variables: daily smoking and heavy smoking. In the current sample, nearly half (47%) of soldiers reported smoking daily, with 35% of all smokers reporting heavy smoking (17% of the entire sample). Daily smoking was associated with demographic (age, gender, education, rank), behavioral health (ACE, alcohol misuse, sleep duration, aggression), and unit characteristics (unit cohesion); only increased combat exposures and aggression were specifically associated with heavy smoking. Interventions focused on the postdeployment period could incorporate messages about alternatives to smoking as a coping strategy while unit interventions or individual counseling addressing aggression could also address smoking as a negative coping strategy.

Correlation
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:
