OBJECTIVE: This study aimed at determining the mean total sleep time (TST) and the relationship between sleep duration and basic socio-demographic factors and BMI sleep problems in Chinese subjects. METHOD: A total of 5926 subjects were randomly selected and interviewed using standardized assessment tools. RESULTS: The reported mean TST was 7.76 h. Short sleepers were significantly older than medium and long sleepers. There were more urban residents who were short sleepers than medium and long sleepers. Short sleepers reported more sleep problems than medium and long sleepers. Short and long sleepers reported more psychiatric disorders than medium sleepers in both sexes, and short sleepers also had more major medical conditions in women. Short sleepers had a lower BMI than medium and long sleepers after controlling for the effects of age and psychiatric disorders in women. CONCLUSIONS: Nationwide epidemiologic surveys in China are needed to further explore the relationship between sleep duration and sleep problems.
