Caffeine Use among Active Duty Navy and Marine Corps Personnel
Abstract
Data from the National Health and Nutrition Examination Survey (NHANES) indicated that 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 were 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 1,708 service members (SMs) completed the questionnaire. Overall, 87% reported using caffeinated beverages greater than or equal to 1 time/week with caffeine users consuming a mean standard error of 226 + or - 5 mg/day (242 + or - 7 mg/day for men, 183 + or - 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 (greater than or equal to 1 time/week) included older age, White race/ethnicity, higher alcohol consumption, and less resistance training. Frequency of caffeine use in these SMs was similar to that reported in civilian investigations, but daily consumption (mg/day) was higher.
