【摘要】：目的探讨寄宿制学校学生膳食营养及贫血状况,为制定有针对性的营养干预措施提供参考。方法采用分层整群抽样法,首先按经济发展水平将我国分为一类、二类、三类地区,3类地区共随机抽取16省,每省抽取1个县的初一年级住校生100人的1所学校,每所学校组织至少100名住校生参与调查,共1 929名,进行基本信息、膳食调查与血红蛋白测定。结果学生每天的能量摄入量为2 151.41 kcal(1 kcal=4.18 kJ),蛋白质摄入量为61.27 g,碳水化物摄入量为303.16 g,脂肪摄入量为78.10 g,铁摄入量为19.79 g,平均贫血率为6.30%。除鱼虾贝类外,不同地区间学生膳食摄入种类差异均有统计学意义(P值均0.05),各类地区能量、蛋白质、碳水化合物、脂肪与铁摄入量差异均有统计学意义(F值分别为96.18,87.02,232.09,132.13,77.04,P值均0.05)。结论寄宿制学校学生的膳食结构有待调整,贫血状况有待改善。
[Abstract]:Objective to explore the status of dietary nutrition and anemia in boarding school students, and to provide reference for the formulation of nutritional intervention measures. Methods the stratified cluster sampling method was adopted. Firstly, according to the level of economic development, China was divided into one class, two and three types of areas randomly selected from 16 provinces, one county in each province, a school with 100 students in grade one. Each school organized at least 100 resident students to participate in the survey, a total of 1,929, for basic information, dietary survey and hemoglobin determination. Results the daily energy intake was 2 151.41 kcal (1 kcal=4.18 kJ), protein intake was 61.27 g, carbohydrate intake was 303.16 g, fat intake was 78.10 g, iron intake was 19.79 g, the average anemia rate was 6.30g). With the exception of shellfish and shellfish, there were significant differences in the types of dietary intake among students from different regions (P < 0.05), and there were significant differences in energy, protein, carbohydrate, fat and iron intake between different regions (F = 96.187.02232.09132.132.1377.04, P = 0.05). Conclusion the dietary structure of boarding school students should be adjusted and anemia should be improved.
