目的 研究暴露于农村生活环境对预防儿童哮喘及致敏的保护作用.方法 向2986名在校儿童父母发放哮喘标准调查表,采用放射性变应原荧光酶免疫吸附实验(RAST-FEIA)检测儿童血清中特异性IgE(sIgE)含量.结果 与在城镇生活的儿童相比,暴露于农村生活环境儿童的过敏性哮喘与非过敏性哮喘、过敏性哮鸣及特应性哮呜危险度显著性降低(OR=0.45,95%CI:0.13～0.96:OR=0.41,95%CI:0.15～0.95;OR=0.32,95% CI:0.11～0.62;OR=0.44,95% CI:0.13～0.91).1周岁内暴露与农村生活环境的儿童过敏性哮喘及特应性致敏危险度较低(OR=0.23,95% CI:0.04～0.91;OR=0.32,95%CI:0.17～0.78);若暴露持续至6周岁,过敏性哮喘及特应性致敏危险度更低(OR=0.21,95%CI:0.03～0.87;OR=0.31,95%CI:0.15～0.78).结论 暴露于农村环境对预防儿童过敏性哮喘及致敏的发生可能有保护作用,持续的暴露能加强此作用.
