Objective To explore the longitudinal correlation between cognitive function (CF) and activities of daily living (ADL) of the rural elderly in Guizhou province, and to provide theoretical basis for preventing and controlling health problems of the elderly. Methods The multi stage cluster random sampling method was used to select the elderly aged 60 years and above from 12 villages in 2 counties (districts) of Guizhou Province as the research objects. In this study, 792 elderly people who participated in two surveys in 2019 (T₁) and 2022 (T₂) and were ≥60 years old at baseline with complete variable values were selected as survey subjects. The cross lagged model was used to investigate the longitudinal relationship between cognitive function and ADL. Results The cross - lagged model showed that T₁ ADL could predict T₂ cognitive function after controlling T₁ cognitive function (β = -0.120, P<0.001). After controlling for T₁ ADL, T₁ cognitive function predicted T₂ ADL (β = -0.099, P=0.005). In the study of the association between two dimensions of ADL and cognitive function, it was found that T₁ IADL could predict T₂ cognitive function after controlling for T₁ cognitive function (β = 0.138, P<0.001). Similarly, after controlling T₁ IADL, T₁ cognitive function could predict T₂ IADL (β = 0. 124, P<0.001). But there was no predictive effect between BADL and cognitive function. Conclusion There is a longitudinal bidirectional correlation between cognitive function and activities of daily living of the rural elderly in Guizhou, only between IADL and cognitive function, suggesting that strengthening the monitoring and intervention of cognitive function of the elderly can help reducing the risk of the decline of IADL in the elderly, and strengthening the training of IADL plays an important role in delaying cognitive decline.
