Abstract:
To explore the relationship between physical activity and subjective life expectancy in an older population. Repeated-measures ANOVA, as well as construction of a cross-lagged model, was conducted with a sample of 4969 older adults from the China Health and Retirement Longitudinal Study data in 2018 and 2020. It was found that T1 subjective life expectancy significantly predicted T2 physical activity (β=0.03, P < 0.01) and T1 physical activity significantly predicted T2 subjective life expectancy (β=0.05, P < 0.05). There was a significant bidirectional predictive relationship between physical activity and subjective life expectancy in older adults, and physical activity is a causal variable for subjective life expectancy.
