    Abstract:
    INTRODUCTION: Electronic cigarettes (EC) are an emerging form of nicotine replacement that has had a discernible increase in prevalence in the general population. Little is known regarding EC use among different military demographic groups or the extent of influence that social determinants of health may have on the behavior. The purpose of this study was to assess the prevalence and correlates of EC use in a select population of active duty U.S. Naval personnel. This study is unique in that it allows for EC behavior comparison between a traditionally healthy demographic (aviators, a subset of aircrew) and a representative general military population sample. MATERIALS AND METHODS: Cross-sectional survey data were collected anonymously and analyzed in 2015-2016. Active duty Naval personnel (n = 977) were asked about ever trying ECs, frequency of use, and when was the last time an EC was used. Participants were assessed similarly regarding cigarette use. Descriptive and inferential statistics as well as multinomial logistic regression analyses were conducted using categorical and ordinal variables assigned to usage and demographic factors. This protocol was approved by the Institutional Review Board at Naval Hospital Portsmouth located in Portsmouth, Virginia. RESULTS: Within the study population, 31.4% have tried ECs, 9.3% were current users, and only 3.8% were dual (EC and cigarettes) users. EC use was significantly associated with paygrade (enlisted), primary job duty (non-aircrew), and education (less than a bachelor degree, p < 0.001, p < 0.01, and p < 0.001, respectively). ECs were used at some point as a smoking cessation tool for 43.6% of current EC users (p < 0.001), 21.6% of current smokers, and only 5.6% of former smokers. Continued EC use after ever trying ECs (30.0%) was only slightly more prevalent as continued cigarette use after ever trying cigarettes (27.3%). Smokers were nearly five times more likely to currently use ECs compared with non-smokers. Trying cigarettes was associated with nearly 12 times the risk for trying ECs compared with those who never tried cigarettes. No significant misuse of ECs was noted; however, several cases of drinking, tasting, and touching EC fluid were reported. CONCLUSION: This study is unique in that it examines the use of electronic cigarettes among selected healthy and baseline groups within the active duty U.S. Navy population. The current prevalence of EC use among active duty personnel is much higher than previously thought. Continued use of ECs after ever trying them appears to exceed that of cigarettes even among healthy populations such as aircrew. The findings of increased risk of EC use among those with lower income and less than a bachelor's degree suggest social determinants of health implications. This study sheds new light on EC use, characteristics of use, addiction implications, and highlights concerns for a growing health risk behavior.
