Objective        To determine the effect of sleep duration and sleep quality on the prevalence of hypertension in Chinese male adults.        Methods        A cross-sectional survey was conducted in a total of 4 519 male adults (over 18 years old) living in Tangshan mining community from September to October 2013. All subjects received anthropometric test

blood test and structured questionnaire survey. Sleep quality were evaluated using the standard Pittsburgh Sleep Quality Index. The relationship of sleep duration or sleep quality with the prevalence of hypertension was analyzed by multivariate logistic regression analysis.        Results        In comparison to the normotensive population

the hypertensive population had shorter sleep duration and poorer sleep quality. Both too short sleep duration and very poor sleep quality significantly increased the prevalence of hypertension in Chinese male adults (OR=1.33

95%CI=1.13-1.56

P0.05；OR=1.81

95%CI=1.44-2.29

P0.05). But when taking the interaction between them into consideration

only those with moderate sleep quality combined with short sleep duration and those with poor sleep quality combined with too short or long sleep duration could significantly increase the risk for hypertension (OR=1.92

95%CI=1.65-2.23

P0.05; OR=2.18

95%CI=1.66-2.86

P0.05; OR=1.55

95%CI=1.25-1.92

P0.05

respectively).        Conclusion        Both short sleep duration and poor sleep quality increase the risk for hypertension in Chinese male adults

and what’s more

these effects can be superposed.
