This research aims to assess the association between night sleep duration and cardiovascular risk by sex among young and middle-aged Chinese adults.Patients and Methods: We used the baseline data of a cohort of adults for physical examination by stratified cluster sampling. The Framingham risk score and the Pittsburgh Sleep Quality Index were used to measure CVD risk and sleep duration, respectively. Demographic characteristics, lifestyle ...
