Mounting research has shown that short sleep duration is associated with obesity in young adults, according to a study reported in Sleep (June 15, 2004). For the study, the researchers tracked 496 young adults for a 13-year period to determine if there was a connection between sleep duration, obesity, and body mass index (BMI). Data was derived from 4 interviews when the participants were ages 27, 29, 34, and 40 years. The interviews focused on psychiatric and medical conditions and health habits.
"?this study shows an association between short sleep duration and obesity that diminished above age 34 years and an association between sleep duration and BMI in young adults. Because sleep duration is a potentially modifiable risk factor, these findings might have important clinical implications for the prevention and treatment of obesity," concluded the authors.
