Background: Sleep disturbance has been shown to cause metabolic and endocrine alternations. Sleep has been known to influence the physical and emotional well being of adolescents by causing substantial biological and psychosocial changes. According to recent estimates, the worldwide prevalence of obesity has doubled since 1980. Lack of adequate sleep predisposes overweight and obesity. Growing evidence suggests that short sleep duration is a risk factor for obesity and its complications.

Objective: The objective was to investigate the association between self-reported usual sleep duration and the prevalence of overweight and obesity among the adolescents of Rewa city, M.P.

Material and Methods: A cross-sectional community-based study was conducted among 744 adolescents aged 10-19 years from Rewa city M.P. India using modified questionnaire and standardized anthropometric measures through house-to-house visits. Data was entered in Microsoft Excel sheet, analysed and interpreted using descriptive statistics.

Results: In our study significantly higher prevalence of overweight/obesity was found among subjects sleeping < 6hours as compared to those sleeping 6 to 8 hours in night.

Conclusion: Short sleep duration would get exaggerated with increase in weight gain and incident overweight/obesity. Further research is needed to understand the mechanisms by which sleep duration may affect weight.
