【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。更多还原

【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.更多还原
