What does this research mean for the field?

Physical activity has a U-shaped, non-linear association with the risk of intrinsic capacity impairment in older adults, with moderate levels providing the greatest protective benefit, though these effects vary significantly across specific functional domains. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

This study aims to evaluate the relationship between physical activity levels and intrinsic capacity impairment in older adults.

Implication

Cross-sectional study examines physical activity's impact on intrinsic capacity in older adults, indicating tailored interventions are essential.

Key Points

This study aims to evaluate the relationship between physical activity levels and intrinsic capacity impairment in older adults.
Data from the 2015 China Health and Retirement Longitudinal Study (CHARLS) with 2307 participants aged ≥60 years was analyzed.
Multivariable logistic regression and restricted cubic spline models were utilized to assess associations and dose-response relationships.
Subgroup analyses were conducted to explore variations across different intrinsic capacity domains.
Physical activity levels were significantly associated with intrinsic capacity impairment after adjusting for confounders.
A U-shaped association was noted, with a risk decrease followed by an increase at activity levels over 2633 MET-min/week.
Domain-specific effects showed cognitive function benefits primarily in moderate activity groups, while locomotion improvements were noted only in the highest activity group.
