Abstract

Aim: To determine the relationship between sleep duration and obesity in Turkish children and adolescents.

Methods: This study was conducted in Turkey with 5358 children aged 6 to 17 years. Height, weight, waist circumference (WC), mid-upper arm circumference (MUAC), triceps skinfold thickness were measured. Body mass index (BMI), arm fat area were calculated. Self-reported sleep duration by parents were obtained.

Results: As sleep duration increased, BMI, which was significantly higher in girls sleeping ≤8 h, decreased (p < 0.05). WC, MUAC, BMI were significantly higher in boys sleeping ≤8 h versus males sleeping ≥10 h. Boys sleeping ≤10 h in 6.0–17.0-years had significantly higher risk of overweight/obesity. In 6.0 to 17.0 years, the risk of overweight/obesity in boys sleeping 9–10 h, 8–9 h and ≤8 h were 1.86-, 1.74- and 2.06-times higher respectively, versus children sleeping ≥10 h (p < 0.05).

Conclusion: Sleep duration may be an important factor for obesity and providing ≥10 h of sleep is recommended as a prevention strategy for obesity.
