Dental Prosthesis Use and Functional Capacity Decline Among Older Japanese Adults

Japan Gerontological Evaluation Study (JAGES) data from a 3-year prospective cohort study of 22,632 older adults aged 65 and over. The dataset supports analysis of the association between dental prosthesis use and functional capacity decline, measured by the Tokyo Metropolitan Institute of Gerontology Index of Competence. Authored by Mari Nakagawa and published under a CC-BY-4.0 license.

Use Cases

• Analyze longitudinal associations between dental prosthesis use and functional capacity decline based on self-reported survey data.
• Investigate protective effects of prostheses on specific functional domains like intellectual activity and social roles.
• Model risk factors for functional decline in older adults with tooth loss using sociodemographic and health behavior covariates.

Strengths

• Large-scale cohort of 22,632 participants provides substantial statistical power.
• Longitudinal design with a 3-year follow-up period allows for analysis of change over time.
• Uses a validated instrument (TMIG-IC) to measure functional capacity across multiple domains.

Limitations

• All data, including prosthesis use and functional capacity, are self-reported, which may introduce bias.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
