OBJECTIVE: To assess the prevalence of obesity and associated health outcomes among US service members and veterans. METHODS: Data from three survey cycles (2001-2008) of the Millennium Cohort Study were used to examine the prevalence of obesity and associated health outcomes. RESULTS: Of the 42,200 individuals, 25% were of normal weight in 2007/2008. Rates of obesity were significantly higher among veterans (32%) compared with service members (20%). Over a 7-year period, obesity rates doubled among both service members (10%-20%) and veterans (14%-32%). Participants with obesity were significantly more likely to be male, older, less educated, in the Army or Navy, and separated/retired from the military. Hypertension, diabetes, and sleep apnea were significantly more common among individuals with obesity compared with participants with normal weight (all P < 0.05). Individuals with obesity also had significantly higher rates of depression and post-traumatic stress disorder than individuals with normal weight and had lower mental and physical functional scores (all P < 0.05). CONCLUSIONS: These findings indicate an urgent need to enhance strategies for preventing and reducing excess weight gain within the military and veteran populations. Such strategies should aim to ensure a fit military force and promote health after military service.
