台灣地區成人睡眠時數與肥胖的相關性研究
The Association between Sleep Duration and Obesity in Taiwanese Adults
摘要
Purpose: Over the past half century, the prevalence of obesity has increased dramatically, while sleep duration has diminished. Several studies conducted in the West have suggested that short sleep duration is associated with increased body weight; in Asia, however, there have been few studies, and their results have been inconsistent. Therefore, the aim of this study was to investigate the relationship between sleep duration and obesity in Taiwanese adults. Methods: This cross-sectional study enrolled 2,929 subjects (1,870 men and 1,059 women) with mean age of 50.5±12.8 years, who received health examination in National Cheng Kung University Hospital during 2001 and 2007. Obesity was defined as body mass index (BMI) ＞25 kg/m2. Subjects were classified by sleep duration into one of three categories (＜6 hours, 6 to 8 hours, ＞8 hours). We applied linear regression to explore the relationship between sleep duration and obesity by gender, adjusting for age, marital status, education level, systolic blood pressure, exercise, smoking, alcohol consumption, and coffee consumption. Results: The sleep duration of obese women was significantly shorter than that of nonobese women (6.2±1.3 vs. 6.5±1.1 hours, p=0.001), but there was no difference in men (6.5±1.1 vs. 6.5±1.1 hours, p=0.581). Multiple linear regression analysis showed that being married, systolic blood pressure, habitual coffee drinking, habitual alcohol drinking, and sleep duration ＜6 hours were independently associated with BMI in men; age, being married, systolic blood pressure, and sleep duration ＜6 hours were independently associated with BMI in women. Conclusion: Our study revealed that short sleep duration was associated with elevated BMI in Taiwanese men and women; furthermore, sleep duration ＜6 hours was associated with increased risk for obesity in women. Therefore, in addition to diet and exercise, sleep duration should be considered when evaluating risk factors for obesity.
