A recent study which involved 442 children who were evaluated for sleep duration , body Mass index(BMI) and waist circumference revealed that sleep duration was significantly associated with waist circumference and that the association remained even after the adjustment of BMI and other factors such as parent income /education, duration of TV viewing and playing sports out side of school. The results suggest that insufficient sleep may lead to weight gain in children.
