Children and adolescents who are considered short sleepers are twice as likely to develop overweight or obesity vs. those who sleep for a longer duration, according to a recent meta-analysis.
“Some epidemiologic studies have observed associations of either short or long sleep duration with obesity, and the relationship between duration of sleep and obesity is U-shaped among adults,” Yanhui Wu, of Yinzhou Hospital and the Medical School of Ningbo University in China, and colleagues wrote. “However, the results of longitudinal associations between sleep duration and obesity were conflicting. Meta-analysis might help to resolve this inconsistency.”
