A good night’s sleep is one of the most important keys to good health—and may also be a key to maintaining a healthy weight. A growing body of research suggests that there’s a link between how much people sleep and how much they weigh. This study was aimed at studying the combined effect of sleep quality and sleep duration on obesity in the Taiwanese adult population. Methods: Data was derived from the MJ Health Screening Center (MJHSC) and was pooled together from the year 2001 to 2010 resulting in a total sample of 571 949 subjects aged between 20 years and a 100. Each examinee completed a self-administered questionnaire and also had their biomedical measures taken. Chi-squared cross tables were used to assess descriptive data whilst bivariate logistic regression analysis was conducted inoder to derive associations with obesity (p value = 0.5 and CI 95%). Results: The prevalence of obesity in the population was 3.8% and more males were obese than female (m=4.8% vs. f=2.8%). However, more males (32.2%) than females (26.2%) slept good and on average more males than females slept for the standard amount of time 7-8hours (m=35.2% vs. f=26.2%). On calculating likelihood of obesity, males were more likely to be obese than females with OR=1.593 and single unmarried participants were more likely to be obese than their married counterparts (OR=1.226). Those who slept poor and short hours and those who slept good and long hours had the highest likelihood of being obese with OR=1.209 and OR=1.213 respectively when compared to the standard (Good sleep quality x Standard sleep quantity). Conclusion: There was a U-shaped association between the combined sleep quality and quantity with obesity occurrence in the Taiwanese population. Those who slept both poor x short and good x long were more likely to be obese that those sleeping ideally. Further studies can help map public health interventions which are focused on weight reductions programs through management of sleep behaviors in adults.
