Rapid postnatal weight gain and visceral adiposity in adulthood: the Fels Longitudinal Study.

Rapid infant weight gain is associated with increased abdominal adiposity, but there is no published report of the relationship of early infant growth to differences in specific adipose tissue depots in the abdomen, including visceral adipose tissue (VAT). In this study, we tested the associations of birth weight, infant weight gain, and other early life traits with VAT, abdominal subcutaneous adipose tissue (ASAT), and other body composition measures using magnetic resonance imaging (MRI) and dual-energy X-ray absorptiometry in middle adulthood (mean age = 46.5 years).
