The short-term and long-term effects of falls on depression: evidence from the CHARLS
摘要
To investigate the short-term and long-term association between falls and depression risk in middle-aged and older adults.
MethodsData from the China Health and Retirement Longitudinal Study (CHARLS, 2011–2020) were used. Cross-sectional analysis included 14,919 participants aged ≥ 45 at baseline, employing weighted logistic regression to assess the association between falls in the past 2 years and depressive symptoms. Longitudinal analysis included 7543 participants, using generalized estimating equations (GEE) to evaluate the long-term impact of baseline fall history on depression risk.
ResultsCross-sectional analysis revealed a significant association between falls and depressive symptoms (adjusted odds ratio [aOR] 1.96, 95% confidence interval [CI] 1.75–2.19). Among fallers, multiple injurious falls increased depression risk by 1.37-fold compared to falls not requiring medical treatment (aOR 1.37, 95% CI 1.03–1.84). Longitudinal analysis confirmed that individuals with a fall history had a 1.27-fold higher depression risk than those without (aOR 1.27, 95% CI 1.13–1.42).
ConclusionRecent falls, particularly multiple injurious falls, increase depression risk in both the short and long term. Targeted prevention strategies should be implemented to reduce fall-related injuries, with enhanced mental health screening for those experiencing injurious falls.
