Geriatric Nutritional Risk and ADL Disability in Rural China, 2016-2018

4,399 community-dwelling adults aged ≥60 years from Donglan County, Guangxi, China were surveyed in a cross-sectional study between 2016 and 2018. The dataset likely contains assessments of nutritional risk (GNRI), activities of daily living (BADL/IADL), and biomarkers for inflammation, metabolism, and body shape. The data was collected and analyzed by Wenjie Liang.

Use Cases

• Analyze associations between nutritional risk scores and functional disability based on GNRI and ADL assessments.
• Investigate mediating effects of body shape and metabolic biomarkers based on ABSI, METS-IR, and TyG indices.
• Perform subgroup analyses for specific health conditions based on the mention of anemia interaction.
• Model nonlinear relationships between nutritional indices and outcomes based on restricted cubic spline analyses.

Strengths

• Includes 4,399 participants from a specific rural population.
• Contains multiple validated assessment tools for nutrition (GNRI) and disability (PSMS, Lawton scale).
• Analyzes several biomarker indices (SIRI, AISI, METS-IR, ABSI, TyG).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects a specific geographic and temporal bias inherent to the single rural Chinese county study.
