Abstract
Purpose: To investigate the relationships of overall and domain-specific physical activities with sleep disorders among Chinese men and women.
Methods: The data of 452,024 Chinese adults aged 35-79 years from The China Kadoorie Biobank Study was analyzed. Sleep disorders were classified as having disorders in initiating and maintaining sleep (DIMS), early morning awakening (EMA), daytime dysfunction (DDF), and any sleep disorders (ASD). Self-reported physical activity was divided into domains of occupational, commuting-related, household and leisure time activities. Gender-specific multiple logistic regression analysis was conducted to identify effects of overall and domain-specific physical activities on risk of sleep disorders.
Results: The mean age at baseline was 50.5±10.4 years, with 40.2% male participants. In total, 12.9% of men and 17.8% of women participants reported having ASD. Moderate to high levels of overall activity were associated with lower risks of DIMS and DDF in both sexes (ORs range: 0.87-0.94). Beneficial effects of occupational, household and leisure time physical activities on sleep disorders were identified only in women (ORs range: 0.84-0.94). However, both moderate and high levels of commuting-related activity were associated with increased risks of DIMS and ASD in men and women (ORs range: 1.07-1.17).
Conclusion: This study confirmed that moderate to high level of physical activities have beneficial effects on sleep among Chinese adults. However, different domains of activity may have varied effects with gender differences, which needs to be taken into consideration in policy making.
