学生营养改善计划地区2012和2013年试点学校膳食供应改善情况

Improvement of food supply in pilot schools attending Nutrition Improvement Program for Rural Compulsory Education Students

目的了解我国"农村义务教育学生营养改善计划"实施1 a后试点学校的膳食供应改善情况,为制定和修正学生营养干预策略提供参考依据。方法采用记账法,对全国2012年3 910所和2013年5 523所实施"农村义务教育学生营养改善计划"学校食堂食物供应情况进行分析。结果实施1 a后,学生粮谷、鸡蛋、豆制品和牛奶的供应情况均有改善(Z值分别为-3.94,-6.80,-8.26,-4.45,P值均<0.01),但蔬菜、禽畜肉和植物油的供应量与干预前差异均无统计学意义(Z值分别为-0.19,1.28,-0.65,P值均>0.05);膳食能量、蛋白质、维生素A、钙、铁和锌的供应情况也有显著改善(Z值分别为-3.84,-3.86,-5.26,-5.83,-2.77,-6.66,P值均<0.01),而维生素C供应量与干预前差异无统计学意义(Z=-1.03,P>0.05)。结论实施"农村义务教育学生营养改善计划"后,试点学校学生膳食供应情况有显著改善,但与参考量比较仍处于偏低水平。

Objective To evaluate and compare the food supply in different catering modes in pilot schools attending National Nutrition Improvement Program for Rural Compulsory Education Students（ NNIPRCES）. Methods Information on food supply of 3 910 NIPRCES schools in 2012 and 5 523 NIPRCES schools in 2013 were collected and compared. Weighed food records were used in the survey. Results After one-year implementation of NIPRCES, the supplies of grain, egg, bean products and milk were significantly improved（ Z =-3.94,-6.80,-8.26,-4.45, P〈0.01）. The dietary supplies of energy, protein, vitamin A, calcium, iron and zinc significantly improved（ Z =-3.84,- 3.86,- 5.26,- 5.83,- 2.77,- 6.66,P 0. 01）. Conclusion After one-year implementation of NIPRCES, food supply shows significant improvement in pilot schools. However, there is still a desire to keep a sustained and healthy school food supply strategy among rural areas in China.
