摘要:
了解西安市“义务教育学生营养改善计划”(以下简称“营养改善计划”)学校食堂的食物供应情况,为学生营养监测及“营养改善计划”的实施提供参考.方法 抽取西安市实施“营养改善计划”区县中6个农村区县,每个区县抽取10%~ 20%食堂供餐的学校,采用记账法对2015年学校食堂的食物供应情况进行调查.结果 共调查58所学校,将学校上报的各种食物分为粮谷类、畜禽肉、蔬菜、鸡蛋、豆制品、植物油六大类.各学校上报的食物种数8~41种不等.粮谷类、鸡蛋、豆制品供应量偏低的学校比例分别为47.6%,74.1%,74.1%.试点地区农村学校6类食物供应量分布差异有统计学意义(x2=251.746,P<0.05).不同季节6类食物供应情况分布差异均无统计学意义(P值均>0.05).结论 西安市“营养改善计划”学校食堂食物供应情况的调查需进一步完善.食堂供餐的学校学生膳食结构不合理.
