Overview

Cross-sectional study finds distinct links between sleep, physical activity, digital use, and depressive symptoms in older adults, highlighting targets for behavioral mental health interventions.

Key Points

  • To examine the associations between sleep duration, physical activity, digital and social participation, depressive symptoms, and life satisfaction among middle-aged and older adults.
  • Cross-sectional analysis of 13,576 middle-aged and older individuals from the 2020 China Health and Retirement Longitudinal Survey (CHARLS).
  • Depressive symptoms were defined as CES-D-10 scores ≥10, and analyses used modified Poisson regression to estimate adjusted prevalence ratios (aPRs) and ordinal logistic regression for life satisfaction while controlling for demographics, socioeconomic status, and health.
  • The weighted prevalence of depressive symptoms was 44.5%, with higher risk observed for sleep deprivation (<7 h/day; aPR = 1.49, 95% CI: 1.33–1.68) and adequate physical activity (aPR = 1.17, 95% CI: 1.04–1.32).
  • Reduced depressive symptoms were linked to recreational activities (aPR = 0.86, 95% CI: 0.77–0.96), watching videos (aPR = 0.87, 95% CI: 0.76–0.99), and playing online games (aPR = 0.65, 95% CI: 0.50–0.83).
  • Overall internet use was correlated with lower life satisfaction (OR = 0.90, 95% CI: 0.81–1.00), and higher depressive symptom rates occurred in women, rural residents, and low-income groups.
