Abstract

Abstract : Objective: Epidemiologic analyses indicate a lack of association between BMI (kg/m 2 ) and mortality among Hispanic adults. Because BMI provides only a surrogate for the real variable of interest, adiposity, this study evaluated associations between measures of body composition and mortality. Methods: Using data from US‐residing Mexican Americans in the National Health and Nutrition Examination Survey (NHANES) III ( n = 4, 480) and NHANES 1999‐2010 ( n = 5, 849), the association between seven measures of body composition measured via anthropometry and bio‐electrical impedance analysis (i.e., waist circumference, waist‐to‐height ratios [WHtR], skinfolds, lean mass, fat mass, percent body fat, and BMI) and all‐cause and cardiovascular and diabetes mortality were examined. Additional analyses were stratified by gender. Results: Waist circumference (hazard ratio [HR]: 1.04, 95% CI: 1.01‐1.07) and WHtR (HR: 1.08, 95% CI: 1.03‐1.14) were weakly associated with an increased all‐cause mortality, while WHtR was associated with an increased risk of diabetes‐related death (HR: 1.26, 95% CI: 1.07‐1.49). In gender‐stratified analyses, there was an increased risk of mortality in females who had increases in WHtR and waist circumference for all‐cause mortality and cardiovascular deaths. Conclusions: Waist circumference and WHtR were associated with increased risk of all‐cause and diabetes‐related mortality in US‐residing Mexican American adults.
