【摘要】：【目的】对陕西省两县农村寄宿制学生营养干预进行效果评价,为探索农村学生营养改善的适宜措施提供依据。【方法】在陕西省淳化县和榆林县,各抽取经济状况相似的2个乡镇为干预组、1个乡镇为对照组,每个乡镇选取小学、中学各1所,干预校学生给予一学年的以补充鸡蛋为主的综合营养干预。【结果】干预组、对照组学生能量、蛋白质、脂肪和碳水化合物摄入量差异无统计学意义。干预组蛋白质供能比为12.4%,显著高于对照组(11.8%)。干预组维生素A、钙、钾、锌摄入量显著高于对照组。除了男性7～9岁组和女性12～15岁组,其他年龄组学生的年龄别身高Z评分(HAZ)和年龄别体质指数Z评分(BAZ)在干预组和对照组中差异均无统计学意义。干预组重度、中度低体重率均显著低于对照组。干预组学生血清维生素B12水平为778.5ng/L,显著高于对照组(654.4ng/L)。【结论】营养干预改善了农村寄宿制学校学生的膳食营养素状况,降低了中、重度低体重率,在一定程度上改善了学生血液微量营养素的营养状况。
[Abstract]:[objective] to evaluate the effect of nutritional intervention on rural boarding students in two counties of Shaanxi Province, and to provide a basis for exploring the appropriate measures to improve the nutrition of rural students. [methods] in Chunhua County and Yulin County of Shaanxi Province, Two villages and towns with similar economic status were selected as intervention group, one township as control group, one primary school and one middle school in each township. The students of the intervention school were given a comprehensive nutritional intervention with egg supplementation for one school year. [results] the intervention group, There was no significant difference in energy, protein, fat and carbohydrate intake among the students in the control group. The ratio of protein to energy in the intervention group was 12.4, which was significantly higher than that in the control group 11.80.Vitamin A, calcium, potassium in the intervention group were significantly higher than those in the control group. Zinc intake was significantly higher than that in the control group. There was no significant difference in age specific height Z score and age specific body mass index Z score between the intervention group and the control group. The level of serum vitamin B12 in the intervention group was 778.5 ng / L, which was significantly higher than that in the control group (654.4 ng / L). [conclusion] nutritional intervention improved the dietary nutrition status of the students in rural boarding schools and decreased the level of vitamin B12. Severe low body weight rate improves the nutritional status of blood micronutrients in students to some extent.
