Lack of sleep and sleep-related breathing problems in children may increases the risk of obesity as a teen.

Children whose SDB peaked later, around 5 to 6 years old, fared better but still had a 60 to 80 percent increased risk of becoming obese. Overall, one-fourth of children in this population-based cohort had an increased statistical risk of obesity that arose from SDB symptoms experienced earlier in life. Obesity was defined as BMI greater than the 95th percentile for age and gender, according to the International Obesity Task Force.
