Objective To explore the standardized clinical screening process and comprehensive supplementary nursing intervention effect of vitamin D deficiency in children, and provide a basis for early identification and precise management of vitamin D deficiency in children. Methods 56 children diagnosed with vitamin D deficiency in our pediatric health department from January 2024 to January 2025 were selected and randomly divided into a control group and an experimental group, with 28 cases in each group, using a random number table method. The control group received routine health guidance and basic supplementation, while the experimental group underwent standardized screening and evaluation, personalized vitamin D supplementation, and systematic nursing intervention. Both groups were intervened for 3 months, and four indicators including serum 25- (OH) D levels, blood calcium levels, clinical symptom improvement rate, and growth and development indicators were observed and compared. Results After intervention, the serum 25- (OH) D and blood calcium levels in the experimental group were significantly higher than those in the control group (P<0.05); The overall improvement rate of clinical symptoms was 92.86%, which was higher than the 71.43% in the control group (P<0.05); The growth in height and body mass was better than that of the control group (P<0.05). Conclusion Standardized clinical screening combined with individualized supplementation and systematic nursing can significantly improve the corrective effect of vitamin D deficiency in children, improve nutritional status and growth and development, and is worthy of clinical promotion.
