Abstract:

Objective To conduct a scoping review of research on the relationship between 24-hour movement behaviours and cognitive function in the elderly，so as to provide references for future research. Methods Totally 8 Chinese and English databases were systematically searched. The search period spanned from the establishment of databases until November 30，2024. According to the scoping review framework，2 researchers independently screened the studies，extracted the data of the included studies，and collaborated on the final analysis. Results A total of 12 papers were included，and the distribution of 24-hour movement behaviors in the elderly was as follows：3.0-5.4 h/d for light physical activity，0.6-1.5 h/d for moderate vigorous physical activity，8.9-12.3 h/d for sedentary behaviour and 6.7-8.4 h/d for sleep. Measures included objective，subjective and subject-objective measures. There are complex interactions among physical activity，sedentary behavior，sleep and cognitive function，which jointly affect cognitive function in the elderly. Conclusion Despite current differences in the measurement of 24-hour movement behaviours，the decreased physical activity，the increased sedentary time，and insufficient or excessive sleep are common problems among the elderly. By increasing physical activity，reducing sedentary behavior and ensuring adequate sleep，the overall cognitive function，executive function of the elderly can be improved. In the future，we should pay attention to the time allocation of 24-hour movement behaviours of the elderly，develop accurate and standardized measurement methods，and promote research in this field.
