This study aimed to estimate associations between combined measurements of BMI and waist-to-hip ratio (WHR) with mortality and incident coronary artery disease (CAD). This study followed 130,473 UK Biobank participants aged 60-69 years (baseline 2006-2010) for 8.3 years (n = 2974 deaths). Current smokers and individuals with recent or disease-associated (e.g., from dementia, heart failure, or cancer) weight loss were excluded, yielding a "healthier agers" group.
Ignoring WHR, the risk of mortality for overweight subjects was similar to that for normal-weight subjects. However, among normal-weight subjects, mortality increased for those with a higher WHR (hazard ratio: 1.33) compared with a lower WHR. Being overweight with a higher WHR was associated with substantial excess mortality (hazard ratio: 1.41) and greatly increased CAD incidence compared with being normal weight with a lower WHR. Thus for healthier agers (i.e., nonsmokers without disease-associated weight loss), having central adiposity and a BMI corresponding to normal weight or overweight is associated with substantial excess mortality. The claimed BMI-defined overweight risk paradox may result in part from failing to account for central adiposity, rather than reflecting a protective physiologic effect of higher body-fat content in later life.
