Objective To determine the relationship of sleep duration and efficiency with obesity in Tehran city children’s.

Methods This study was conducted in Tehran city with 270 children aged 6 to 9 years. Heights, Weight, were measured and Body mass index (BMI), was calculated. Directly measured height and weight data were used to define overweight and obesity according to the centers for disease Control and Prevention’s (CDC) 2000 Growth Charts. Nocturnal sleep duration and sleep efficiency were recorded by the Actigraphy method.

Results Sleep duration showed a significant inverse association with weight (p<0.05) and height (p<0.005) during 7 day and weekdays. A significant relationship was found between Sleep efficiency and weight, BMI, weight for age (p<0.05) during weekdays and weekend days.

Conclusion In the current study, we found Sleep pattern may be an important environmental factor for obesity in school age children’s. These findings are important because sleep duration is a potentially modifiable risk factor that could be important to consider in the prevention and treatment of childhood obesity.
