Objective

2

To analyze the traditional Chinese medicine （TCM） constitution of 1-year-old children undergoing health examinations and provide theoretical support for pediatric TCM-based care and health preservation.

Methods

2

A retrospective analysis was conducted on the physical examinations and TCM healthcare data of children who underwent health examinations at Heqing Community Health Service Center in Pudong New Area， Shanghai. According to relevant standards， TCM constitution types were identified， and an analysis of TCM constitutions was performed. Logistic regression analysis was used to explore the influencing factors of biased constitutions.

Results

2

①A total of 649 children's data were included in the analysis. Among them， children with a single constitution were more common， while those with mixed constitutions were less frequent. The types in descending order of frequency were： balanced constitution （83.05%）， yin deficiency constitution （7.55%）， phlegm damp constitution

（2.93%）， qi deficiency constitution （2.62%）， damp heat constitution （0.92%）， yang deficiency constitution （0.77%）， special endowment constitution （0.00%）， yang excess constitution （0.00%）， and food stagnation constitution （0.00%）. ②There were no statistically significant differences between genders in the distribution of single and mixed constitutions （

Conclusions

2

The TCM constitution of 1-year-old children is predominantly characterized by a balanced constitution. The biased constitutions are influenced by factors such as anemia， past infection history， and appetite status， all of which contribute to the development of biased constitutions. Strengthening early dietary and health guidance for children can help reduce the occurrence of biased constitutions.
