Abstract

To examine the relationship between obesity and mortality as a function of polygenic risk for obesity among older US adults.Using data from the 1994-2014 Health and Retirement Study in conjunction with genome-wide data, we evaluated the risk of mortality as a function of obesity classification, an individual’s polygenic risk score (PGS) for obesity, and their interaction, stratified by sex.
