Waist-to-Height Ratio Changes and Mortality Risk in Chinese Older Adults, 2011-2018

A 2011-2018 longitudinal study of 4,065 Chinese adults aged 60+ investigates the link between changes in waist-to-height ratio and all-cause mortality. The research, authored by Juanxia Miao and based on the Chinese Longitudinal Healthy Longevity Survey, documented 1,449 deaths among participants. Cox proportional hazards models were used to analyze associations, adjusted for demographic, behavioral, and health covariates.

Use Cases

• Modeling mortality risk based on changes in waist-to-height ratio.
• Studying longitudinal health trajectories in an older adult population.
• Investigating the predictive power of anthropometric indicators for all-cause mortality.
• Analyzing survival curves for different categories of body composition change.

Strengths

• Based on a national longitudinal survey with 4,065 participants.
• Analysis includes 1,449 documented mortality events over a 7-year period.
• Uses established statistical methods (Cox proportional hazards models, Kaplan-Meier curves).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (30.5 KB), suggesting limited scope or summary-level data.
