To the Editor A study by Dr Walter and colleagues1 found differential associations between a polygenic genetic risk score and BMI across different US birth cohorts. In 2015, we published a study about genetic inheritance and body mass.2 One of our analyses was basically identical to theirs in which the following hypothesis was tested: “… that the genetic influence on body mass is greater among recent cohorts than among earlier ones,” using data from the Health and Retirement Study (HRS).
