摘要： 目的　比较上海市杨浦区两个社区儿童过敏性疾病的患病情况，分析发病因素和疾病控制水平，提高临床医师对儿童过敏性疾病的认识和诊疗水平。方法　于2019年12月至2020年1月对杨浦区两个社区（较新社区为新江湾城社区；老旧社区为五角场社区）0～5岁的儿童家长进行过敏性疾病问卷调查，问卷包括国际儿童哮喘和过敏研究（ISAAC）问卷哮喘、鼻炎、湿疹的核心问题并添加儿童家庭背景信息、室内外环境、生活习惯等问题。对收集到的儿童过敏性疾病相关数据进行分析研究。结果　本次问卷调查共收到新江湾城社区及五角场社区有效问卷1247份（新江湾城社区590名，男298名，女292名；五角场社区657名，男346名，女311名）。喘息发生率分别为：新江湾城社区20.4%，五角场社区12.6%，P＜0.001；鼻炎发生率分别为：新江湾城社区40.0%，五角场社区28.0%，P＜0.001；湿疹发生率分别为：新江湾城社区17.5%，五角场社区8.5%，P＜0.001；食物过敏发生率分别为：新江湾城社区23.3%，五角场社区16.6%，P＝0.004；过敏性疾病家族史阳性率分别为：新江湾城社区34.2%，五角场社区23.0%，P＜0.001。结论　上海市杨浦区新江湾城社区儿童过敏性疾病的发生率明显高于五角场社区；外界环境因素和生活方式的改变在儿童过敏性疾病发生发展中起到越来越重要的作用。
