Background: Worldwide, at least 2.8 million people die each year due to overweight and obesity, and an estimated 35.8 million (2.3%) of global Disability Adjusted Life Years (DALYs) are caused by overweight and obesity. Many studies in Ethiopia showed that overweight and obesity is caused due to increased intake of energy-dense food, physical inactivity, changing modes of transportation and increasing urbanization. However, there is no published article showing that short sleep duration is an independent risk factor to cause overweight and obesity for adolescents in the country. Objective of the study: To measure the magnitude of overweight/obesity and its association with short sleep duration among high school adolescents’ in Addis Ababa, Ethiopia. Methods: School based cross-sectional study was conducted with a sample size of 405. Data was collected by self-administered questionnaire, entered and cleaned using EPI INFO version 7, and was exported to SPSS version 20 for analysis. Body mass index (BMI) was computed using weight and height (Kg/m2). Descriptive statistics using frequencies, proportion and table were used to present the study results. Binary logistic regression analysis was employed to see association between short sleep duration and overweight/obesity. To evaluate the association between short sleep duration and overweight/obesity, both crude odds ratio and adjusted odds ratio with 95% confidence interval were computed. Results: The combined prevalence of adolescents’ overweight and obesity was 18.2%, the specific prevalence for overweight and obesity were 14.4% and 3.8%, respectively. Adolescents with short sleep duration (<8 hours/day) were significantly at risk for being overweight/obese as compared to adolescents with normal sleep duration (8-10 hours/day) [AOR = 3.7 (95% CI: 1.9- 7.0)]. Conclusions and recommendations: The findings of this study showed that higher prevalence rates of overweight and obesity were observed among adolescents in the study area. Short sleep duration was strongly associated with overweight/obesity during adolescence. Hence, results of this study suggest that adolescents should receive educational intervention on adequate duration of sleep at night to reduce the risk of being overweight or obese.
