Nutritional Vulnerability Among Seoul's 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 dataset, shared by Misung Lee, was last updated in March 2026 and uses the Nutrition Quotient for the Elderly (NQ-E) to categorize respondents and analyze sociodemographic and dietary characteristics associated with nutritional vulnerability.

Use Cases

• Predicting nutritional vulnerability risk based on sociodemographic factors like gender and education level.
• Analyzing the association between food literacy scores and nutritional outcomes among the elderly.
• Comparing dietary and lifestyle characteristics between nutritionally vulnerable and non-vulnerable groups.
• Modeling the impact of living arrangements (e.g., living alone) on nutritional status for targeted intervention planning.

Strengths

• Dataset is based on a survey of 720 elderly individuals, providing a specific sample size.
• Analysis includes specific statistical results, such as an odds ratio of 2.88 for men being more vulnerable than women.
• Focus is on a defined population (Seoul, 2024) and a specific metric (NQ-E) for nutritional assessment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying raw data is unknown, which may limit suitability assessment.
• Data reflects a specific geographic (Seoul) and temporal (2024) context, limiting generalizability.
