OBJECTIVES
We examined the asthma-control benefit of moving into an asthma-friendly Breathe-Easy home (BEH).
METHODS
We used a quasi-experimental design to compare the asthma outcomes of 2 groups of low-income children and adolescents with asthma: 34 participants who moved into a BEH, and a local matched cohort of 68 participants who had received a previous asthma-control intervention. Both groups received in-home asthma education. BEHs were constructed with moisture-reduction features, enhanced ventilation systems, and materials that minimized dust and off-gassing.
RESULTS
BEH residents' asthma-symptom-free days increased from a mean of 8.6 per 2 weeks in their old home to 12.4 after 1 year in the BEH. The proportion of BEH residents with an urgent asthma-related clinical visit in the previous 3 months decreased from 62% to 21%. BEH caretakers' quality of life increased significantly. The BEH group improved more than did the comparison group, but most differences in improvements were not significant. Exposures to mold, rodents, and moisture were reduced significantly in BEHs.
CONCLUSIONS
Children and adolescents with asthma who moved into an asthma-friendly home experienced large decreases in asthma morbidity and trigger exposure.
目的
我们研究了搬入哮喘友好型宜居房屋（BEH）对哮喘控制的益处。
方法
我们采用准实验设计，比较了两组低收入哮喘儿童和青少年的哮喘结局：34 名搬进 BEH 的参与者，以及当地匹配的 68 名接受过先前哮喘控制干预的参与者。两组均接受了家庭哮喘教育。BEH 采用了减少潮气、增强通风系统以及最小化灰尘和排放的材料建造。
结果
BEH 居民在旧居时每两周哮喘无症状天数平均为 8.6 天，在 BEH 居住 1 年后增加到 12.4 天。在过去 3 个月内因紧急哮喘相关临床就诊的 BEH 居民比例从 62%下降到 21%。BEH 看护者的生活质量显著提高。BEH 组的改善程度大于对照组，但大多数改善程度的差异并不显著。BEH 中霉菌、啮齿动物和潮气的暴露显著减少。
结论
搬入哮喘友好型住宅的哮喘儿童和青少年的哮喘发病率和触发因素暴露显著降低。
