摘要:
目的了解不同供餐模式下中小学生血清维生素D 水平，为科学供餐预防学生维生素D 缺乏提供依据。 方法采用分层整群随机抽样法，抽取北京市朝阳区8所走读学校，形式为学校供餐、企业送餐和无供餐。每个 学校各年级选取1 个班学生为研究对象，采用电化学发光法检测其血清25 羟基维生素D[25-(OH)D]水平。 结果共检测564 例中小学生的血清25-(OH)D， 平均水平为（19.10±6.79） mg/L， 处于缺乏状态。 25-(OH)D 水平随年级升高有逐渐下降趋势，差异有统计学意义（P<0.05）。进食学校供餐和企业送餐的学生血 清25-(OH)D 水平分别为（20.19±7.12） mg/L 和（19.24±6.40） mg/L，显著高于无供餐的学生水平（16.63± 5.80） mg/L。结论北京市朝阳区中小学学生维生素D 轻度缺乏。进食学校供餐和企业送餐的小学生维生素D 水平高于无供餐学生。
Abstract:
Objective To assess the vitamin D level among the primary and secondary school students with different catering models， and to provide bases for preventing vitamin D deficiency disease and serving food scientifically. Methods Eight Day schools were selected using stratified cluster sampling methods from Chaoyang District in Beijing. Their meal catering models were provided by school or company or no meal. Students in a class were chosen from every grade in all enrolled schools. Serum 25-hydroxyvitamin D[25-(OH)D] concentrations were measured using electrochemiluminescence detection method. Results The mean serum 25-(OH)D concentration of 564 students was （19.10±6.79） mg/L, and they were all in deficiency conditions. Serum 25-(OH)D levels were declined with the grade rising （P<0.05). 25-(OH)D level of students received meals from school and company were （20.19±7.12） mg/L and （19.24 ± 6.40） mg/L, respectively, and all higher than that of the students without food supply （16.63 ± 5.80） mg/L. Conclusion Primary and secondary school students in Chaoyang District have mild vitamin D deficiency. The students’ serum 25- (OH)D Levels with school meals and company meals are higher than those students without any food supply.
