Abstract Data from the National Health and Nutrition Examination Survey NHANES indicate 89% of Americans regularly consume caffeine, but these data do not include military personnel. This cross-sectional study examined caffeine use in Navy and Marine Corps personnel, including prevalence, amount of daily consumption, and factors associated with use. A random sample of Navy and Marine Corps personnel was contacted and asked to complete a detailed questionnaire describing their use of caffeine-containing substances, in addition to their demographic, military, and lifestyle characteristics. A total of 1708 service members SMs completed the questionnaire. Overall, 87% reported using caffeinated beverages ≥1 time-week, with caffeine users consuming a mean ± standard error of 226 ± 5 mg-day 242 ± 7 mg-day for men, 183 ± 8 mg-day for women. The most commonly consumed caffeinated beverages % users were coffee 65%, colas 54%, teas 40%, and energy drinks 28%. Multivariable logistic regression modeling indicated that characteristics independently associated with caffeine use ≥1 time-week included older age, white race-ethnicity, higher alcohol consumption, and participating in less resistance training. Prevalence of caffeine use in these SMs was similar to that reported in civilian investigations, but daily consumption mg-day was higher. View Full-Text
