[Association between sleep status and prevalence of major chronic diseases].

Sleep is an important physiological activity. With the changing life style in this modern world, the average duration of sleep in human beings is decreasing, and the prevalence of sleep disorder or insomnia is increasing. Short duration and disorders of sleep or insomnia may often lead to increased prevalence/incidence of major chronic diseases such as hypertension, diabetes, obesity and dyslipidemia. Currently, chronic diseases have become the main causes of death and with high disease burden among the Chinese. In the Healthy China Initiative (2019-2030), prevention and control of chronic diseases including "moving forward" , "slowing down the upward trend of the prevalence of insomnia" as the expected indices and "extending the sleep duration of adults to 7-8 hours a day" as the advocacy index, were all called for. In this group of articles, basic data for sleep status of adults in different regions of the country was provided to help understand the relations between sleep and major chronic diseases, and strategies related to prevention and control of chronic diseases.
