Body composition and development of diabetes: a 15-year follow-up study in a Japanese population.

Few longitudinal studies have examined the association between diabetes risk and body composition in Asians. The aim of this prospective cohort study was to determine the role of body composition, estimated by whole-body dual-energy X-ray absorptiometry, in the development of diabetes and to examine the impact of body composition on diabetes risk in normal weight (body mass index (BMI) <23 kg/m2) and overweight/obese groups (≥23 kg/m2).
