摘　　要：目的 了解嘉兴市学龄期儿童血清维生素D营养状况,分析其可能的影响因素。方法 选取2022年在嘉兴市妇幼保健院儿童保健科就诊的6~11岁学龄期儿童888名,采集静脉血测定血清25-羟维生素D[25-hydroxy-vitamin D,25-(OH)D]含量,收集相关问卷信息并采用多因素Logistic回归分析影响维生素D水平的可能因素。结果 888名学龄期儿童中,25-(OH)D中位水平[55.11(43.08,68.79)]nmol/L,学龄期儿童维生素D缺乏率7.0%,不足率31.7%,总体异常率38.7%。学龄期儿童血清维生素D水平和异常率比较,性别、年龄、居住地、户外活动及不同季节,差异有统计学意义(P<0.05);有无挑食偏食、主要养育人文化水平,差异无统计学意义(P>0.05)。多因素Logistic回归分析提示性别、年龄和季节是维生素D缺乏与不足的显著影响因素。结论 嘉兴市6~11岁学龄期儿童普遍存在维生素D缺乏与不足,需定期检测,合理补充,以防止相关并发症的发生。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.
