Association of overweight, obesity and insufficient sleep duration and related lifestyle factors among school children and adolescents

Abstract

Abstract Objectives To assess the prevalence of overweight, obesity and Insufficient Sleep Duration (ISD) and to investigate their relationship with related lifestyle factors among school-aged students. Obesity in childhood and adolescence is a serious health concern as it may have long term risk for overweight and obesity in adulthood. Methods This is a cross-sectional study of 1,611 students aged between 10 and 18 years from Al Ain city, United Arab Emirates. Data were collected using a multistage stratified random sampling method using a validated questionnaire and the level of significance was set at p<0.05. Results The prevalence of overweight and obesity was 42.4%. ISD was 36.6% among students. Higher BMI was significantly related to being a male and inactive (95% CI=0.03–0.23), daily coffee consumption (95% CI=0.03–0.1), older age (95% CI=0.01–0.02), less average sleep duration (95% CI=−0.02 to −0.003) and spending more time on TV/videogames (95% CI=0.01–0.07). The likelihood of ISD was significantly lower among students who consumed breakfast daily (OR=0.58, 95% CI=0.41–0.83), spent less time on smart devices (OR=0.63, 95% CI=0.47–0.84), and never consumed energy drinks or soft drinks (OR=2.64, 95% CI=1.13–6.16, OR=2.02, 95% CI=1.24–3.29, respectively). Conclusions The prevalence of overweight and obesity among school-aged students is high. ISD and related lifestyle factors are significantly associated with overweight and obesity. Study findings emphasize the need to address and implement successful strategies for a healthy lifestyle starting from early childhood to combat the increasing rates of overweight and obesity in adulthood.
