中文摘要:
      了解中国农村留守儿童膳食营养状况,为农村留守儿童营养干预提供科学依据。方法采用多阶段分层整群随机抽样方法,随机选择农村2~7岁留守儿童1278名和对照儿童1273名作为调查对象。采用3日膳食称重法和食物摄人频率法进行膳食调查,并以中国营养学会推荐的膳食营养素参考摄入量(DRIs)为依据,评价农村留守儿童膳食能量和各种营养素的摄人状况。结果农村留守儿童膳食以粮谷类和蔬菜类为主,留守儿童肉禽水产类、水果类及零食类等食物的摄入量低于对照儿童,差异有统计学意义。农村留守儿童能量、三大产热营养素及部分矿物质(钙、锌、硒、钾)和维生素(维生素A、维生素B1、维生素B2)的摄入量均低于推荐摄入量。农村留守儿童能量及主要营养素普遍摄入不足,能量摄入不足率在50%以上,蛋白质摄人不足率达80%以上,而钙、锌等矿物质和维生素B1、维生素B1等维生素的摄入不足率达90%以上。蛋白质来源中,优质蛋白质摄入量仅占总蛋白质摄入量的35%,而植物蛋白质占65%。此外植物性铁的摄入比例明显偏高,达到87%。结论中国农村留守儿童的膳食结构不尽合理,能量和多种营养素摄入不足,能量、蛋白质及铁的来源不合理,膳食营养状况有待改善。
英文摘要:
      understand the dietary nutrients among rural stranded children.Methods 2551 children aged 2 to 7,including 1278 stranded children in the rural areas and another 1273 children served as controls were selected,using multistage stratified cluster random sampling.Dietary survey was performed with three-day weighing dietary method and questionnaire on food intake.Data on diet were analyzed and evaluated by the Dietary Reference Intakes (DRIs) recommend by Chinese Nutrition Society,to evaluate the levels on energy and nutrient intake among stranded children in the rural areas.Results The dietary pattern among rural stranded children mainly consisted of grains and vegetables,but the intakes of animal products,fruits,and snacks were significantly less than in the control group.The intakes of three major energy-producing nutrients were below the recommend nutrient intake.Minerals as calcium,zinc,selenium,kalium and vitamins as vitamin A,B1,B2were insufficient.Most of the rural stranded children took nutrients insufficiently,with 50% lack of adequate energy and 80% of protein,90% of minerals (calcium,zinc etc.) and vitamins (vitamin B1 and vitamin B2 etc.).Sources from high quality protein was insufficient,only consisting 35% of the total protein,but overabundant (over 64 % ) from the plants.The intake of plant-sourced iron was overabundant,accounted for 87%.Conclusion The dietary pattern was unsatisfactory with insufficient intake of energy-sourced proteins and some nutrients.The sources of energy,protein,and iron were mostly obtained from underbalaneed foods.It is necessary to improve the dietary nutrients status among rural stranded children aged 2-7 years.
