Table 1_Dental prosthesis use and subsequent functional capacity decline among older adult

The Japan Gerontological Evaluation Study (JAGES) provides a 3-year prospective cohort dataset of 22,632 older adults aged 65 and over. It contains self-reported data on dental prosthesis use, functional capacity measured by the TMIG-IC index, and sociodemographic factors. The dataset was created by Mari Nakagawa and published on figshare in 2026.

Use Cases

• Analyze the association between dental prosthesis use and functional decline based on TMIG-IC total scores.
• Investigate protective effects on specific functional domains like intellectual activity based on TMIG-IC subdomain scores.
• Model risk factors for functional capacity decline based on sociodemographic variables, health behaviors, and comorbidities.
• Conduct longitudinal analysis of aging trajectories based on the three-year follow-up period.

Strengths

• Large cohort of 22,632 participants provides substantial statistical power.
• Longitudinal design with a three-year follow-up period from 2016 to 2019.
• Includes detailed self-reported measures of functional capacity across multiple domains via the TMIG-IC index.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and cultural bias inherent to the JAGES study, which focuses on Japanese older adults.
• Row count is unknown, which may limit suitability assessment.
