Obesity leads to many health outcomes such as type 2 diabetics, cardiovascular disease, and stroke. Finding cause of obesity is vital for managing weight status. Sleep plays one of the key roles for obesity management. This study aims to investigate the association of sleep deprivation or sleep quality with obesity. A cross sectional study was conducted between 225 Iranian adults (109 male and 116 female) aged 20-55 years old. Anthropometrics were measured followed by assessment of dietary intake, physical activity and sleep habit were performed via interviewed validated questionnaires. Subjects were divided in two groups of normal weight (36.3%) or overweight/obese (64%) based on WHO standards (2000) for comparing of sleep duration. However, Sleep quality was analyzed based on two groups of shorter sleeper and longer sleeper (less than 6h 48% or more than 6 h/day 52%). Overweight/obese subjects showed more trouble in sleeping including falling asleep (50% vs. 32.1%, p<0.01), waking up during the night (59.7% vs. 38.3%; p<0.01), and did not get enough sleep (86.1% vs. 70.4%; p< 0.01) compared to normal weight subjects. Shorter sleep duration had higher body weight and BMI (77.4±13.3 vs. 70.7±14.5, 27.7±3.4 vs. 25.9±3.9 p<0.01 respectively) compare to longer sleeper. Poor sleeper had significantly higher risk for being overweight or obese (OR: 2.0, 95% CI: 1.18-3.37, p<0.05) compared to less problem and longer sleeper. Thus, less sleep quality and sleep duration increase the risk of being overweight and obese. Hence, strategies may consider on sleep pattern for the management of obesity.
