“…11,25 The proportion of short and long sleepers were 30.9% and 6.9%, respectively, in this study, which is inconsistent with the figures of 13.9% and 21.4%, respectively, in Beijing. 11 The inconsistency may be partly due to the differences in sampling and assessment methods, the study period, sample characteristics, and the lack of consistency in definitions of short and long sleep.…”

“…38 Social inequality leads to unhealthy choices in poorer population which, in turn, could affect sleep duration. 39 Some studies found that shorter sleep was associated with higher BMI, 24,25,40 but this was not replicated in the multivariable analysis of this study. Perhaps an unhealthy lifestyle might have a moderating effect on the association between sleep duration and BMI.…”

Study Objectives: Pattern of sleep duration and its correlates have rarely been reported in China. This study examined the sleep duration and its relationship with sociodemographic variables, lifestyle, mental health, and chronic diseases in a large Chinese adult population. Methods: This cross-sectional study used multistage stratified cluster sampling. A total of 17,320 participants from Jilin province were selected and interviewed using standardized assessment tools. Basic socio-demographic and clinical data were collected. Sleep duration was classified as short (< 7 h per day), long (> 9 h per day) and medium sleep (7-9 h per day). Results: The mean age of the sample was 42.60 ± 10.60 y, with 51.4% being female. The mean sleep duration was 7.31 ± 1.44 h. Short and long sleepers accounted for 30.9% and 6.9% of the sample, respectively. Multinomial logistic regression analysis revealed that older age, current smoking, irregular meal pattern, lack of physical exercise, poor mental health, and chronic diseases or multimorbidity were positively associated with short sleep. Being married and living in rural areas were, however, negatively associated with short sleep. In addition, living in rural area, current smoking, current alcohol use and lack of physical exercise were positively associated with long sleep, while older age and lower education were negatively associated with long sleep. Conclusion: Given the high frequency of short sleep and its negative effect on health, health professionals should pay more attention to sleep patterns in general health care. Nationwide epidemiologic surveys in China are needed to further explore the relationship between sleep duration and health. I NTRO DUCTI O NTo maintain optimal health, sleep duration of 7-9 h is generally needed for adults.1 There is compelling evidence that both habitual short and long sleep durations are associated with poor health outcomes.2-4 A U-shaped relationship between sleep duration and mortality was found in some but not all studies, 5,6 although the explanation for this association is unknown.7 It is assumed that short sleep could be due to voluntary sleep restriction or certain chronic diseases, whereas long sleep is commonly associated with sleep disturbances, chronic diseases, and psychiatric disorders. 8 Identifying the relationship between sleep duration and other clinical variables may help understand the pathomechanism of increased mortality associated with short and long sleep duration. 9Most studies on sleep duration and its correlates have been conducted in the West. Evidence is accumulating that socioeconomic and cultural factors play an important role in sleep-related disturbances including short and long sleep duration. [10][11][12][13][14] Over the past two decades, China has experienced rapid socioeconomic changes leading to a number of social problems including increased divorce rates, smoking and alcohol use, BRIEF SUMMARY Current Knowledge/Study Rationale: Habitual short and long sleep durations are usually associated with po...

“…20,21 Sleep is also critically involved in systemic physiology, including metabolism, [22][23][24][25][26] appetite regulation, 27,28 immune and hormone function, [29][30][31][32][33] and cardiovascular systems. [34][35][36][37] Sleep duration is associated with mortality risk [38][39][40] and with illnesses ranging from cardiovascular 41 and cerebrovascular 42 disease to obesity, 43 diabetes, 44 cancer, 45,46 and depression. In 2013, the American Academy of Sleep Medicine and Sleep Research Society received a one year grant, renewable annually for up to five years, from the CDC entitled the "National Healthy Sleep Awareness Project."…”
