Military deployment with combat experience is linked to higher risk of smoking among military service members
New research from the American Journal of Public Health finds that deployment accompanied with military combat is a predictor of smoking initiation among U.S. military personnel.

The study used data from the Millennium Cohort Study, designed to evaluate long-term health effects of military service. The study launched in 2001 and will continue through 2022, collecting survey data every three years. Researchers reviewed smoking initiation among those who had never smoked and relapse among those who were former smokers. Among these groups, the study assessed military characteristics including pay grade, service branch and combat deployment; mental health history; history of life stress; and demographic data.

Results from the study indicate that among older and younger military personnel, deployment with military combat was associated with a higher risk of smoking initiation. Further, having a previous mental disorder, serving in the Army and lower educational achievement were independently associated with a higher risk of smoking initiation.

“Although deployment with combat experience was associated with tobacco initiation, notably absent was an association between noncombat deployment and risk of smoking initiation, which suggests that deployment alone may not serve as a sufficient cause for the initiation of this behavior, ” the authors conclude.

“Smoking as a coping mechanism and stress reduction aid may explain the higher risk we noted in participants with combat experiences, previous mental health disorders and high life stressors,” they further explain.

For smokers, e-cigarette use is linked to lower likelihood of decreasing cigarette consumption
Smokers who have used e-cigarettes at least once were found to be less likely to quit or decrease cigarette consumption compared to smokers who have never used e-cigarettes, according to new research from the American Journal of Public Health.

Researchers drew survey responses from 1000 smokers using data from the California Smokers Cohort survey. All respondents were between the ages of 18 and 59 who had smoked at least 100 cigarettes in their lifetime. Telephone surveys for study participants were completed at both a baseline level and a follow-up level about one year later.

Respondents were asked about their awareness and use of e-cigarettes, along with questions regarding tobacco use behavior, intention to quit and quit attempts. The study determined responses to the e-cigarette survey questions in relation to three outcomes: cigarette quit attempts, reduction in the number of cigarettes smoked and current abstinence from smoking.

According to the results, smokers with any history of e-cigarette use were less likely after one year to reduce cigarette smoking or completely quit for one month or more, than smokers who have never used e-cigarettes. These findings held true even when other factors including smoking status, intention to quit and smoking dependence were controlled for. Though not statistically significant, the data also showed that smokers who had used e-cigarettes at least once were more likely to attempt quitting during the study’s follow-up period.

“The study findings contradicted our primary hypothesis that smokers who had ever used e-cigarettes would be more likely to abstain from smoking cigarettes at 1-year follow-up than those who stated they would never use these products,” the study’s authors write.

“These findings are at odds with data from trials and experimental studies demonstrating that e-cigarettes have some positive influence on quitting behavior — comparable to that of the nicotine patch — although these studies showed very low rates of success,” the authors explain.
