Korean Infant Dietary Supplement Use from Birth to 24 Months

A Korean birth cohort study tracked 137 infants from birth to 24 months of age, with follow-ups at 2, 6, 12, and 24 months. The dataset, created by Jiyoung Jeong and shared on figshare, contains structured questionnaire data on supplement administration, feeding methods, and family history of allergies. It was last updated on 2026-05-26.

Use Cases

• Analyze longitudinal trends in probiotic and vitamin D administration based on infant age.
• Model the determinants of supplement use based on feeding method (breastfeeding, formula, mixed).
• Investigate the association between cesarean section birth and supplement administration likelihood based on reported odds ratios.
• Compare supplement administration patterns between infants with and without a family history of allergic diseases.

Strengths

• Longitudinal design with data collected at four specific time points (2, 6, 12, and 24 months).
• Includes data from 137 infants, with a reported 82% overall supplement administration rate.
• Contains specific findings, such as the 38.6% multivitamin administration rate after 12-24 months.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to a single Korean birth cohort.
