Sleep quality was assessed using the Pittsburgh Sleep Quality Index. <Results> The distribution of the subjects was 56.9% for Taeumin and 43.1% for non-Taeeumin., Poor sleep quality increased both BMI and waist circumference in Taeeumin. In men Taeeumin, sleep duration was correlated with BMI, and sleep quality was correlated with waist circumference. The prevalence of obesity was significant difference according to sleeping duration in men Taeeumin, it was the highest at 6 hours of sleeping time. <Conclusions> Sleep duration and sleep quality was associated with obesity in Taeeumin.
