Activity Patterns and Cognitive Control in 121 Older Adults with Chronic Disease Status

A 2026 cross-sectional study of 121 community-dwelling older adults (mean age 71.4 ± 6.5 years) examines the relationship between 24-hour activity patterns, chronic disease status, and inhibitory control. Data includes accelerometer recordings, Stroop task scores for inhibitory control, and questionnaire-derived covariates. The dataset, authored by Li Zhan and shared under a CC-BY-4.0 license, is a 90.1 KB document containing the study's analysis and results.

Use Cases

• Modeling the association between moderate-to-vigorous physical activity (MVPA) duration and inhibitory control scores based on the proportional substitution analysis.
• Investigating the main effect of chronic disease status on cognitive performance using the reported group comparison metrics.
• Exploring the dose-response relationship between the number of chronic diseases and inhibitory control decline as indicated in the sensitivity analysis.
• Replicating the component data analysis methodology to explore multivariate relationships between daily activity patterns, health status, and cognitive outcomes.

Strengths

• Includes data from 121 participants with a mean age of 71.4 years and a breakdown of 75 females and 86 individuals with chronic diseases.
• Results provide specific effect sizes, such as a 0.243-unit increase in inhibitory control for a 30-minute shift to MVPA.
• Analysis adjusts for potential confounders and includes sensitivity analysis, as described in the methodology.

Limitations

• Row count and column-level documentation are unknown; field semantics must be inferred after download.
• The cross-sectional design limits causal inference, and the stratified results are noted as exploratory, requiring validation in larger studies.
• The dataset is a 90.1 KB document, indicating a limited scope focused on study results rather than raw participant-level data.
