Body Composition, Mortality in Mexican Americans

Obesity; ePub 2018 Aug 1; Howell, Mehta, Ejima, et al

Waist circumference and waist‐to‐height ratios (WHtR) were associated with increased risk of all‐cause and diabetes‐related mortality in US‐residing Mexican American adults, according to a recent study. 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 7 measures of body composition measured via anthropometry and bio‐electrical impedance analysis (ie, waist circumference, 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. Researchers found:

  • Waist circumference (hazard ratio [HR]: 1.04) and WHtR (HR: 1.08) were weakly associated with an increased all‐cause mortality, while WHtR was associated with an increased risk of diabetes‐related death (HR: 1.26).
  • 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.
