Obesity has been linked to several lifestyle factors, including sleep. Studies have shown a connection between lack of sleep and higher body mass index in adults and children, but that relationship may hold true for teens as well.
A new study presented at the annual meeting of the Pediatric Academic Societies in Vancouver in early May showed an association between sleep deprivation and a higher BMI. Researchers looked at data on 723 adolescents, average age about 15, and gave each one an accelerometer, which measures movement. The study participants were also asked about their sleep habits on weekdays and weekends, how often they had problems sleeping, and calorie consumption.
