Beta=Difference in body composition outcome as a function of each independent variable. SE=Standard error

^aEstimates are adjusted for sex, age at assessment, educational attainment and cranial radiation exposure

^bScreen time=hours per day spent sitting and watching TV or using a computer outside of work over last 30 days
