Leong et al. develop a generative deep learning model that produces analyzable dual energy X-ray absorptiometry (DXA) scans from 3D body surface scans. Model-generated DXA scans are analyzed using clinical commercial software and yield accurate quantities of fat, lean, and bone mass for total body and body subregions.

Childhood obesity remains a global epidemic. Here, using objective measurements, the authors show that sedentary time increased from 6 h/day in childhood to 9 h/day in young adulthood, and was cumulatively associated with increased total and trunk fat mass. Both light or moderate-to-vigorous physical activity similarly partly reversed risk.
