UNFIT FOR SERVICE: THE IMPLICATIONS OF RISING OBESITY FOR US MILITARY RECRUITMENT

This paper contributes to the literature on the labor market consequences of unhealthy behaviors and poor health by examining a previously underappreciated consequence of the rise in obesity in the USA: challenges for military recruitment. Specifically, this paper estimates the percentage of the US military-age population that exceeds the US Army's current active duty enlistment standards for weight-for-height and percent body fat, using data from the series of National Health and Nutrition Examination Surveys that spans 1959-2008. We calculate that the percentage of military-age adults ineligible for enlistment because they are overweight and overfat more than doubled for men and tripled for women during that time. As of 2007-2008, 5.7 million men and 16.5 million women exceeded the Army's enlistment standards for weight and body fat. We document disparities across race and education in exceeding the standards and estimate that a further rise of just 1% in weight and body fat would further reduce eligibility for military service by over 850?000 men and 1.3 million women. The paper concludes with a discussion of the implications of these findings for military recruitment and defense policy. Copyright (C) 2011 John Wiley & Sons, Ltd.
