ABSTRACT

Background

Numerous studies have confirmed that sleep duration affects physical and mental health. However, limited evidence has been explored regarding the influences associated with nap time and night sleep time among Chinese older adults.

Methods

Based on the data from the China Longitudinal Study on Health and Retirement (CHARLS), we collected information included basic demographic characteristics, psychosocial and health factors. And we used SPSS 25.0 for statistical description and regression analysis.

Results

A total of 1,737 samples were included for statistical analysis. Logistic regression found that age, residential address, pension, life satisfaction, depression degree, ADL score, sleep quality and nap time had significant influences on older adult’s night sleep time, while gender, age, sleep quality and night sleep time will effect nap time.

Conclusion

These findings have important significance for relevant departments to promote healthy living habits and active aging for older adults, and improve the occurrence of adverse health outcomes among older adults.
