Is it time for bed? Short sleep duration increases risk of obesity in Mexican American children.

ABSTRACT:

Objective

Cross-sectional studies show that sleep is related to childhood obesity. We aimed to examine the longitudinal impact of sleep on the risk of obesity in Mexican American children.

Design and methods

Using linear regressions, we examined wheth
