Nutritional Vulnerability Among Seoul Elderly: Analysis of 2024 Food Survey Data

720 elderly individuals aged 65 years or older from the raw data of the Seoul Food Survey 2024. The data was analyzed to identify nutritionally vulnerable individuals using the Nutrition Quotient for the Elderly (NQ-E) and examine associated sociodemographic and dietary characteristics. The dataset was published by Misung Lee on figshare in March 2026.

Use Cases

• Predicting nutritional vulnerability risk based on sociodemographic factors like gender and education level mentioned in the description.
• Analyzing the association between food literacy scores and nutritional outcomes as described in the logistic regression results.
• Comparing dietary and living situation characteristics between nutritionally vulnerable and non-vulnerable elderly groups.
• Training models to identify high-risk subgroups, such as elderly men living alone, for targeted intervention planning.

Strengths

• Dataset includes 720 survey respondents, a specific sample size.
• Analysis provides specific odds ratios (e.g., OR=2.88 for men) linking characteristics to nutritional vulnerability.
• Data is focused on a defined population and time: elderly in Seoul from the 2024 survey.

Limitations

• Row count for the underlying raw data is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a 181.3 KB PDF, which is a small file; the underlying structured data may not be directly accessible.
