目的 探讨农村母亲和儿童土源性线虫感染对学龄前儿童喘息、哮喘和皮肤点刺试验(SPT)阳性的影响。方法 收集2020年4月—2021年3月在运城市中心医院门诊进行健康体检的居住在农村地区的学龄前儿童及其母亲。通过问卷收集母亲与儿童基本资料,及关于喘息/哮喘的情况。收集研究对象粪样,采用改良加藤厚涂片法检测土源性线虫感染情况,并进行SPT试验,收集研究对象过敏特应性数据。应用多因素非条件logistic回归分析探讨影响儿童哮喘、喘息、SPT阳性的相关因素。结果 本研究中儿童及其母亲各2 014人,母亲的土源性线虫感染率为14.40%(290/2 014),学龄前儿童的土源性线虫感染率为7.99%(161/2 014)。有喘息症状的儿童117例,发生率为5.81%(117/2 014);哮喘149例,发生率为7.40%(149/2 014);SPT阳性304例,阳性率为15.09%(304/2 014)。早产儿、母亲有过敏史、家中有人吸烟是儿童喘息的危险因素(P < 0.05,OR > 1);儿童性别为女、完全母乳喂养是儿童喘息的保护因素(P < 0.05,OR < 1)。母亲有过敏史、家中有人吸烟、家中种植花草是儿童哮喘的危险因素(P < 0.05,OR > 1);儿童性别为女、完全母乳喂养是儿童哮喘的保护因素(P < 0.05,OR < 1)。母亲有过敏史是儿童SPT阳性的危险因素(P < 0.05,OR > 1),儿童性别为女、儿童有土源性线虫感染、母亲有土源性线虫感染是儿童SPT阳性的保护因素(P < 0.05,OR < 1)。结论 母亲和儿童土源性线虫感染可能会降低儿童过敏性疾病的发生。
