Abstract :

Background and objectives: Recent studies on various populations indicate that sleep deprivation is one of the potential risk factors predisposing Adolescents to obesity. Since there is a significant rise in obesity among Indian Adolescents and because research indicating the role of sleep in development of obesity among Indian population is scant, the current study was undertaken with the objective to assess the effect of sleep duration on obesity among urban adolescents. Methods: A cross sectional study was conducted between July 2012 to December 2012 in Vadodara city. Total 1050 participants were randomly selected from 15 schools in the age group of 11 to 19 years after taking written informed consent from school authority. A pre-tested, semi structured, self administered questionnaire was used which includes demographic information, dietary information and physical activity questionnaire. Anthropometric measurements such as height, weight were done for each of the adolescents. BMI of each was calculated and Adolescents were classified as overweight and obese by the WHO Reference 2007 with respect to their age and sex. Results: 45% participants were taking less than seven hours sleep per day. Obese adolescents were observed to have less sleep than non-obese adolescents (P < 0.0002). Conclusion: Inadequate sleep duration may be one of the risk factor for obesity among adolescents but further research is required to find out the mechanisms through which sleep affects obesity in this population.
