目的探讨以IMFeD策略为主的综合干预对孤独症儿童营养素摄人、饮食行为问题以及对孤独症儿童家长营养及饮食相关知识知晓的干预效果。方法随机选择孤独症儿童49例，采用24h膳食回顾法评估患儿营养素摄人情况，自拟问卷完成儿童饮食及相关行为问题调查。通过对基线调查、3个月随访以及6个月终期调查结果的统计分析，评价IMFeD对孤独症儿童营养素摄入、饮食行为问题以及家长饮食知识知晓的干预效果。结果干预完成后，孤独症儿童饮食行为问题中胃口差、食物偏好、不良进食习惯和家长的不良喂养行为均减少（均为P〈0．05）；家长营养及饮食知识知晓率由61．3％提升至77．5％；孤独症儿童能量、维生素C、钠、蛋白质、维生素B6、磷、钾、硫胺素和叶酸的摄入水平有显著改善（P均〈0．05）。结论以IMFeD干预策略为主的综合干预手段对改善孤独症儿童的膳食营养素摄人、减少其饮食行为问题、提高家长正确营养及饮食知识知晓率均有明显作用。
