For young adults transitioning to life after school, sleep duration may be compromised to accommodate many lifestyle changes. Recent studies show that short sleep duration creates metabolic and hormonal changes that increase the risk of obesity. We examined whether sleep duration relates to BMI in 1799 20–22 yr old Filipino men and women from the 2005 Cebu Longitudinal Health and Nutrition Survey. Number of hours of sleep was based on reported usual wakeup and bed times. Multivariable regression models that adjusted for socioeconomic status, energy intake, activity levels, and other potential confounders showed that number of hours of sleep was negatively associated with BMI [β=−0.13, 95% CI(−0.21, −0.04)]. Compared to those who usually slept 6–10 hours, those with <6 hours sleep were at greater risk of being overweight or obese [Odds ratio: 1.75, 95% CI (1.07 to 2.88)]. About 55% of the sample were men and a likelihood‐ratio test showed no significant gender‐sleep interaction. Wake‐up time other than in morning hours (4–10AM) was not associated with any measure of obesity nor did it modify the BMI‐ sleep duration relationship. Findings from this community‐based study contribute to the increasing research on sleep deprivation as another possible pathway to obesity. NIH Grant No. 5R03TW008133‐03
