Evaluation Of Nutrition For Lunch Of The Children Of Migrant Workers’ Private Schools In One District Of Shanghai

[Objective] To investigate the nutritional status of lunch and develope students’ physical in ten primary schools of migrant workers’children in one district of Shanghai, and evaluate them, to help to formulate the scientific and reasonable lunch meal plan which might improve the students’nutritional status.[Methods] By weighing method and accounting method to survey the lunch of ten primary schools of migrant workers’ children during the district five consecutive days in one week, and investigate the students’physical growth status. Use some self-designed questionnaires including the weight of food materials in each school canteen, the actual intake amount of meals every day. Two schools random sampled from the 10 schools were choosen for the pre-investigation.[Results] The average intake of energy (1051.1±246), protein (35.7±10.6g), carbohydrate (124.2±31.8g), iron (6.8±2.6mg) and Vitamin C (35.5±27.6mg) from the lunch meals of 10 primary schools for migrant workers’children, which were all more than the recommended intake. Calcium (173.4±134.5mg), zinc (5.2±1.5mg), Vitamin A (162.0±151.9μgRE) and Vitamin B2 (0.34±0.14mg) were less than the recommended intake. The ratio of three kinds of energy (carbohydrate, protein and lipid) nutrients was unreasonable. Ten school lunch meals could be divided into three models with clustering analysis,.The ratio of three kinds of energy (carbohydrate, protein and lipid) nutrients were 14.45%、 42.32% and 43.23% respectively in the first kind of dietary pattern,15.65%、21.96% and 62.39% in the second pattern, and 12.75%、31.13% and 56.12% in the last pattern respectively. The students’BMI distributions of percentage among three kinds of dietary pattern had statistical significance (P<0.05), excepting the boy group of 11 years old(the fifth grade).[Conclusion] In above primary schools the lunch dietary pattern was unreasonable, and ratio of nutrients intake was inadequate. The students’ BMI distributions of percentage were difference among three different kinds of dietary pattern’s schools.. The variety of foods for pupil’s lunch should be increased in these schools, to improve its nutritional quality, to promote students’ physical and mental health growth.
