Association between sleep and obesity in adults / 预防医学

ABSTRACT

Objective@#To examine the associations of sleep with overweight/obesity and central obesity in adults, so as to provide insights into improving sleep quality and preventing obesity in adults.@*Methods@#Demographics, height, body weight, waist circumstance and sleep status were collected from the Hubei Provincial Surveillance Program for Adult Chronic Diseases and Their Risk Factors in 2020. Subjects' sleep condiction, overweight/obesity and central obesity were descriptively analyzed. The associations of sleep with overweight/obesity and central obesity were examined using a multivariable logistic regression model.@*Results@#A total of 17 789 participants were recruited, with an average age of (56.21±13.05) years, 61.50% women, and mean duration of (7.18±1.56) h/d. There were 7 019 participants with snoring/asphyxia/suffocation (39.46%), 6 108 participants with sleep difficulty (34.34%), 8 064 participants with night waking at least twice (45.33%), 268 participants taking hypnotics (1.51%), and 6 267 participants with early morning awakening and difficulty in sleep again (35.23%), and there were 8 960 participants with overweight/obesity (50.37%) and 6 148 participants with central obesity (34.56%). Multivariable logistic regression analysis showed that sleep duration of <7 h/d (OR=1.081, 95%CI 1.007-1.159), snoring/asphyxia/suffocation (OR=2.367, 95%CI 2.222-2.521), and night waking at least twice (OR=1.106, 95%CI 1.028-1.191) significantly correlated with overweight/obesity, and sleep duration of >8 h/d (OR=0.834, 95%CI 0.761-0.913), snoring/asphyxia/suffocation (OR=2.153, 95%CI 2.019-2.297), and night waking at least twice (OR=1.193, 95%CI 1.105-1.288) were statistically associated with central obesity.@*Conclusion@#Sleep duration, snoring/asphyxia/suffocation and night waking are associated with overweight/obesity and central obesity.
