Late Bedtimes May Be Linked To Weight Gain Over Time.

On its website, CBS News (10/3, Welch) reported that research published in Sleep suggests that “going to bed later during the workweek is associated with weight gain over time.” Investigators looked at “data on more than 3,300 teens and young adults recorded at different intervals over the course of about 15 years.”

HealthDay (10/3, Preidt) reported that the investigators “found that each extra hour of late bedtime was associated with a more than two-point increase in body mass index (BMI).” The data indicated that the association “between late bedtimes and BMI increase was not significantly affected by total sleep time, amount of exercise, or time spent in front of computers or televisions.”
