Association between drinking behavior and sleep duration in Chinese adults: findings from the China Health and Nutrition Survey

Background:To examine the association between alcohol drinking and short sleep duration among Chinese adults.Methods:Based on inclusion and exclusion criteria,28,167 records of 15,074 adults longitudinal data were obtained from the China Health and Nutrition Survey for the period from 2004 to 2011.A multilevel logistic regression model was employed to explore the association between alcohol drinking and sleep duration.Results:Compared with nondrinking participants,a high drinking frequency was positively correlated with a short sleep duration in both the males(odds ratio(OR)=1.33,95%confidence interval(CI)=1.20–1.48,P<0.001)and females(OR=1.60,95%CI=1.18–2.18,P=0.003)before the covariates were adjusted.After adjusting for age,residence area,education level,marital status,smoking,coffee consumption,tea consumption,and activity level,this association remained significant in the males(OR=1.31,95%CI=1.17–1.46,P<0.001)but not in the females(OR=1.16,95%CI=0.85–1.59,P=0.340).Conclusion:The present results suggest that a high drinking frequency was positively correlated with a short sleep duration in male population.Comprehensive measures therefore need to be implemented to improve sleep duration,especially to increase awareness of the dangers of drinking alcohol.
