Abstract

To provide precise prevention strategies for Parkinson's disease (PD), this study used data from the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2020 and employed a combination of cross-sectional and cohort analyses to systematically investigate the association between sleep patterns and PD risk. The study revealed, for the first time in a Chinese community-based population, significant age and gender associations between sleep patterns and PD risk. Cross-sectional analysis indicated a significant negative correlation between sleep duration and PD risk in individuals aged ≤60 years, while a U-shaped trend was observed in those >60 years, with the highest risk occurring at approximately 5.2 h of sleep. Cohort analysis further revealed that among individuals with sleep disorders, the incidence of PD was higher in those aged ≤60 years than in those aged >60 years; in contrast, whereas among those without sleep disorders, the incidence was generally higher in women than in men, with this difference being more pronounced in individuals with longer sleep duration. In summary, this study provides a basis for differentiated sleep interventions tailored to specific demographic groups and underscores the public health importance of sleep management in the prevention of PD.
