Early-Life Nutrition and Tonsil Grading in Preschool Children from Yulin City

A cross-sectional dataset of 2,786 preschool children aged 2–7 years from 17 kindergartens in Yulin City, collected by Guangwei Guo. It includes physical examination data for palatine tonsil grading and parent questionnaire data on early-life nutrition, with 816 valid matches. The dataset was last updated on March 19, 2026.

Use Cases

• Analyze sex-stratified associations between feeding patterns and tonsil grading based on age-adjusted ordered logistic regression results
• Investigate the risk of tonsillar hypertrophy based on exclusive formula feeding during 0–6 months, as suggested in the description
• Compare the effects of formula introduction timing (0–6 months vs. 6–12 months) on tonsil grading outcomes
• Study the prevalence of palatine tonsillar hypertrophy (grades III–IV) in a preschool population

Strengths

• Dataset includes 2,786 children, providing a substantial sample size for a cross-sectional study
• 816 valid matches between physical examination records and parent questionnaire data ensure linked analysis
• Analysis is stratified by sex and uses age-adjusted ordered logistic regression, providing methodological detail

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count for the underlying data tables is unknown, which may limit suitability assessment
• Data is from a single city (Yulin City), which may reflect geographic bias
