Relationships of sleep duration with sleep disturbances, basic socio-demographic factors, and BMI in Chinese people

Association between sleep pattern and body mass index among undergraduate health colleges’ students at Qassim University, Saudi Arabia

“…An inverse association between BMI and sleep difficulty and sleep duration was reported in other study which performed among University students [48] also, among females rather than males from the general population of China. [49] Sleep difficulties may represent a risk factor for increasing in BMI. This study may improve the knowledge regarding this public health topic in non-clinical populations, stressing the need for health professionals to pursue strategies to promote adequate sleep and eating patterns to prevent disorders from both areas.The aim of the present study is to explore the associations between sleep patterns and BMI among undergraduate female students in health colleges, at Qassim University through hypothesizing that BMI is associated with sleep pattern and comparison of good sleepers and those with sleep problems will show increased BMI which is theoretically related to sleep disorders.…”

“…[55,56] Most previous studies have shown an inverse association between BMI and sleep difficulty and duration. [43,57,58] Even with the different age group as Soares et al, [48] who conducted his study among university students or specific gender as Xinag et al, [49] who targeted females rather than males from the general population in China. One study showed that short self-reported sleep duration is linked to elevated BMI and may change appetite hormones [47] and in addition, a very recent study by Peltzer and Pengpid [59] confirmed an association between short sleep duration and increased BMI.…”

“…[60] Report on the association of sleep and BMI in the clinical sample and in community samples are mixed and do not show a consistent association between sleep patterns and BMI. [61] However, the inverse association between sleep difficulties and BMI [49,62] is unexpected considering the findings of most studies on sleep restriction and weight/obesity which revealed that short/long sleep and weight increase/obesity are associated. [62,63] There are some proofs that sleep education programs and cognitive behavior interventions can improve sleep in college students.…”

Relationship of Sleep Duration with Sociodemographic Characteristics, Lifestyle, Mental Health, and Chronic Diseases in a Large Chinese Adult Population

“…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] weakening of family ties, and an increasing social and economic gap between the rich and poor. 16,17 All of these changes and problems may have a significant effect on health, including sleep duration.…”

“…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 poor health outcomes. The patterns of sleep duration and its correlates have been rarely examined in China.…”
