Comparison

Moderate-to-vigorous physical activity derived… vs Lower levels of MVPA

Design

Cross-sectional

Key result

Higher moderate-to-vigorous physical activity was positively associated with better global cognitive function among older Chinese adults (standardized β = 0.38; 95% CI 0.34-0.42).

Overview

MVPA associated with better global cognition longitudinally; leaves open whether increasing activity improves outcomes in trials.

Key Points

  • This research investigates how moderate-to-vigorous physical activity relates to cognitive function in older Chinese adults, focusing on the impact of depressive symptoms and age.
  • Cross-sectional survey of 5318 community-dwelling adults aged ≥60 from CHARLS 2020
  • Cognitive function assessed with education-adjusted z-scores from various cognitive tests
  • Survey-weighted regression analysis adjusted for sociodemographic, health, and behavioral factors.
  • Higher MVPA associated with better cognitive performance (standardized β = 0.38, 95% CI 0.34–0.42)
  • Depressive symptoms partially mediated the MVPA–cognition association (indirect effect = 0.08, 95% CI 0.06–0.10)
  • Age enhanced the positive MVPA–cognition link, with stronger effects in older individuals (β = 0.045 at ∼77 years).

Structured PICO

Is moderate-to-vigorous physical activity associated with better global cognitive function in community-dwelling older Chinese adults?

P
Population
5,318 community-dwelling Chinese adults aged ≥60 years participating in the 2020 wave of the China Health and Retirement Longitudinal Study.
E
Exposure
Moderate-to-vigorous physical activity (MVPA) derived from the International Physical Activity Questionnaire–Short Form
C
Comparator
Lower levels of MVPA
O
Outcome
Global cognitive function assessed using education-adjusted z-scores constructed from episodic memory, figure drawing, and mental status items

Main Result

Effect estimate: standardized β = 0.38 (95% CI 0.34-0.42)

Higher moderate-to-vigorous physical activity is associated with better global cognitive function in older Chinese adults, an effect partially mediated by lower depressive symptoms and strengthened at older ages.

Limitations

  • cross-sectional design precludes causal inference
  • Cross-sectional design precludes causal inference

Cite This Study

Song et al. (2026) conducted a cross-sectional in cognitive function (n=5,318). Moderate-to-vigorous physical activity (MVPA) was evaluated on global cognitive function (standardized β = 0.38, 95% CI 0.34-0.42). Higher moderate-to-vigorous physical activity was positively associated with better global cognitive function among older Chinese adults (standardized β = 0.38; 95% CI 0.34-0.42).
