Objective This study evaluates the application effect of vitamin D in childrens height promotion treatment. Methods 80 children aged 0-6 years who were treated in the health care department from January 2024 to December 2024 were selected and randomly divided into two groups: treatment group (40 cases) and control group (40 cases). The treatment group was given an appropriate amount of vitamin D supplementation every day, and the control group maintained a regular diet and exercise intervention. All children were tested for height, weight and vitamin D levels before treatment, 3 months and 6 months after treatment, and the differences in height increase and vitamin D level changes between different groups were analyzed. Results The height increase of children in the treatment group was significantly higher than that in the control group 6 months after treatment, and the vitamin D level was significantly increased. The average increase in height increase in the vitamin D treatment group was 10.5±0.8 cm, while that in the control group was 7.2±0.6 cm (P<0.05). The vitamin D level in the treatment group increased by an average of 15.2 ng/ml, while that in the control group was only 4.3 ng/ml (P<0.05). The proportion of children with vitamin D deficiency in the treatment group decreased significantly. Conclusion Vitamin D supplementation can significantly promote childrens height growth and improve vitamin D levels, which has a positive effect on childrens growth status.
