Concurrent Associations between Sleep Duration and Screen Time with Childhood Obesity
Abstract
Objectives: Obesity is a multifactorial condition showing a rapid rise worldwide, especially in children and adolescents. The present study aims to investigate the impact of sleep duration, TV watching, and dietary intake on the risk of childhood obesity.
Subjects and methods: A cross-sectional study was undertaken among 270 primary school children in Tehran, Iran. Sleep duration was measured using an ActiGraph device worn on the wrist. Using a questionnaire completed by parents, screen time (TV, video games, etc.) was estimated. Also, weight, height, and body mass index (BMI) were obtained. Data were analyzed with SPSS software (version 18, IBM Corporation).
Conclusion: Screen time is significantly associated with BMI, diet, and sleepin Iranian school children. Further studies are required to elaborate these associations.
Results: Lower BMI and longer sleep duration were associated with less screen time (p < 0.01). Higher daily energy (1673.4 ± 405.3 kcal), total fat (55.3 ± 19.3 g),carbohydrate (238.5 ± 67.1 g), sugars (114.3 ± 34.9 g), and snack (37.4 ± 19.3 g)consumption as well as lower daily fiber (7.9 ± 3.7 g) and vegetable and fruit (2.6 ±1.3 servings) intakes were significantly correlated with longer screen time in children (p < 0.05). Lower fiber (8.1 ± 4.2 g) as well as fruit and vegetable (2.6 ±1.4 servings) consumption were related to longer sleep duration (≥ 540 min/day) (p< 0.01
