Abstract:
Objective To understand the nutritional status of serum vitamin D among school-age children in Jiaxing and analyze its possible influencing factors.Methods A total of 888 school-age children aged 6-11 who were treated in the Department of Child Health,Jiaxing Maternal and Child Health Hospital in 2022 were selected,and their venous blood was collected to determine the serum 25-hydroxy-vitamin D[25-(OH)D]content.Relevant questionnaire information was collected and the possible factors affecting vitamin D level were analyzed by multivariate Logistic regression.Results Among 888 school-age children,the median level of 25-(OH)D is[55.11(43.08,68.79)]nmol/L,and the vitamin D lack rate of school-age children is 7.0%,the deficiency rate is 31.7%,and the overall abnormality rate is 38.7%.There were significant differences in serum vitamin D level and abnormal rate among school-age children in gender,age,place of residence,outdoor activities and different seasons(P<0.05).There was no significant difference in whether they were picky eaters and partial eaters,and the educational level of the main caregivers(P>0.05).The multivariate Logistic regression analysis indicated that sex,age and season were the significant influencing factors of vitamin D lack and deficiency.Conclusion Vitamin D deficiency is common among school-age children aged 6-11 in Jiaxing,which requires regular testing and reasonable supplementation to prevent related complications.
