【摘要】：目的了解上海民工小学自供营养午餐营养素供给状况,为改善民工子女膳食营养供给提供依据。方法随机抽取上海市2个区县约50%的民工小学作为研究对象,用食物称重记账法进行膳食调查。结果民工小学自供午餐的能量、钙、锌、维生素A、维生素B1和维生素B2的平均供给量均低于标准值,差异均有统计学意义(t值分别为5.91,47.68,5.42,5.35,6.48,21.15,P值均0.01)。所有学校钙供给量都低于标准的60%;维生素A和维生素B2供给量低于标准60%的学校比例分别为66.7%和87.5%。所有学校均未提供奶类;91.6%的学校大豆及豆制品的供给比例低于标准值的60%;动物性食品的供给量普遍偏多,91.6%的学校供给量超过了标准值。结论上海民工学校供给的午餐膳食结构不合理,矿物质和维生素缺乏严重。应增加奶类、大豆及豆制品和绿色蔬菜的供给量,适当减少肉类的供给,并加强针对学校和家长的健康教育。
[Abstract]:Objective to investigate the nutritional status of self-feeding lunch in Shanghai migrant workers' primary schools, and to provide the basis for improving the dietary nutrition supply of migrant workers' children. Methods 50% primary schools of migrant workers in two districts and counties of Shanghai were randomly selected as the study objects. Results the average supply of energy, calcium, zinc, vitamin A, vitamin B1 and vitamin B2 were lower than the standard value. The difference was statistically significant (5.91 / 47.68 / 5.42 / 6.486.48 / 21.15P), respectively. The calcium supply of all schools was below the standard level of 600.The proportion of schools with vitamin A and vitamin B2 below the standard 60% was 66.7% and 87.5.The milk was not provided in all schools. In 91.6% of schools, the supply ratio of soybean and soybean products was less than 60% of the standard value, and the supply of animal food was more than 91.6%. Conclusion the lunch meal structure provided by Shanghai migrant workers' school is unreasonable. The shortage of minerals and vitamins is serious. We should increase the supply of milk, soybean and soybean products and green vegetables, reduce the supply of meat properly, and strengthen the health education for schools and parents.
