Abstract

Obesity is a worldwide health problem that has reached pandemic proportions. In the military, obesity and overweight are associated with health problems, attrition from military service, and reduced job performance. National and international organizations suggest body mass index (BMI) as a population screening tool to define overweight and obesity. BMI is calculated as weight/height2 (kg/m2). Four categories of adult BMI are underweight (<18.5 kg/m2), healthy weight (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), and obese (=30.0 kg/m2). This article reports on a systematic review and meta-analysis examining the association between BMI and injury risk among military service members (SMs). Studies were selected for review if they involved military personnel, were prospective or retrospective observational studies, and contained original quantitative data on injury risk at all four BMI levels. Nine studies met the review criteria. Pooled data from these investigations indicated that underweight, overweight, and obese individuals were at 1.17 (95% confidence interval [95%CI]=1.07-1.28), 1.03 (95%CI=1.01-1.06), and 1.15 (95%CI=1.11-1.20) times higher risk of injury than healthy weight individuals, respectively. Compared with healthy weight SMs, military personnel with both low and high BMI are at higher injury risk.
