Longitudinal Investigation of Smoking Initiation and Relapse Among Younger and Older US Military Personnel
Abstract
Objectives: We examined whether military service, including deployment and combat experience, were related to smoking initiation and relapse.
Methods: We included older (panel 1) and younger (panel 2) participants in the Millennium Cohort Study. Never smokers were followed for 3 to 6 years for smoking initiation, and former smokers were followed for relapse. Complementary log-log regression models estimated the relative risk (RR) of initiation and relapse by military exposure while adjusting for demographic, health, and lifestyle factors.
Results: Deployment with combat experience predicted higher initiation rate (panel 1: RR = 1.44; 95% confidence interval [CI] = 1.28, 1.62; panel 2: RR = 1.26; 95% CI = 1.04, 1.54) and relapse rate (panel 1 only: RR = 1.48; 95% CI = 1.36, 1.62). Depending on the panel, previous mental health disorders, life stressors, and other military and nonmilitary characteristics independently predicted initiation and relapse.
Conclusions: Deployment with combat experience and previous mental disorder may identify military service members in need of intervention to prevent smoking initiation and relapse.
