Abstract Objective To understand the status of pediatricians' understanding of vitamin A deficiency and the application status of vitamin A supplements, and analyze the influencing factors. Methods A self-made questionnaire was used to survey on pediatricians (pediatric specialists and child health care doctors) in the “children health care WeChat group”. Univariate and multivariate disordered multi-classification Logistic regression analyses were used to analyze the influencing factors of vitamin A supplement application. Results A total of 1 900 pediatricians completed the questionnaire survey. Among them, 72.9% would recommend parents to use vitamin A supplementation in clinical practice. Pediatricians who had received vitamin A-related training were more likely to recommend parents to use vitamin A supplements. Among them, the OR values (95%CI) of training within 1 year and within 1-3 years were 6.434 (1.954-21.178) and 9.287 (2.207-39.080). In addition, compared with tertiary hospitals, pediatricians in secondary hospitals would recommend parents to use vitamin A supplements according to the situation in a lower proportion, with an OR value (95%CI) of 0.437 (0.222-0.862). More than 99.0% of pediatricians knew at least one kind of vitamin A source, high risk factors of deficiency and related diseases. About 50.0% of pediatricians knew the diagnostic criteria of vitamin A deficiency and marginal vitamin A deficiency. And 85.2% of pediatricians believed that continuous supplementation of vitamin A was needed, but they had different understanding of the start time, end time, and dosage. Conclusion Most pediatricians know a lot about vitamin A. The application rate of vitamin A supplements is high. However, there are still many unreasonable aspects of vitamin A supplementation due to the lack of uniform guidelines. The related training and education should be carried out for pediatricians.
