社区卫生工作者(CHW)帮助家庭减少暴露于室内哮喘诱因的有效性尚未被研究。总共有274名低收入哮喘儿童被随机分配到高强度或低强度组。社区卫生工作者走访了所有家庭，以评估暴露情况，制定行动计划，并提供床罩。高强度组还接受了清洁设备和一年内五到九次的检查，重点是减少哮喘的触发因素。哮喘触发综合评分在高强度组从1.5 6降至1.19(Δ=−0.37，95%CI 0.13，0.61)，低强度组从1.6 3降至1.4 3(Δ=−0.2 0，95%CI 0.004，0.4)。这一指标因干预而产生的差异在P=0.096水平上显著。在干预年中，高强度组在凝结、蟑螂、水分、清洁行为、粉尘重量、尘螨抗原和切点以上总抗原的测量方面也有改善，低强度组没有表现出影响。CHW能有效减少低收入儿童的哮喘暴露量。需要进一步研究，以确定特定干预措施和结构改进对哮喘触发暴露和健康的有效性。
The effectiveness of community health workers (CHWs) assisting families in reducing exposure to indoor asthma triggers has not been studied. In all, 274 low-income asthmatic children were randomly assigned to high-or low-intensity groups. CHWs visited all homes to assess exposures, develop action plans and provide bedding encasements. The higher-intensity group also received cleaning equipment and five to nine visits over a year focusing on asthma trigger reduction. The asthma trigger composite score decreased from 1.56 to 1.19 (Δ=− 0.37, 95% CI 0.13, 0.61) in the higher-intensity group and from 1.63 to 1.43 in the low-intensity group (Δ=− 0.20, 95% CI 0.004, 0.4). The difference in this measure due to the intervention was significant at the P= 0.096 level. The higher-intensity group also showed improvement during the intervention year in measurements of condensation, roaches, moisture, cleaning behavior, dust weight, dust mite antigen, and total antigens above a cut point, effects not demonstrated in the low-intensity group. CHWs are effective in reducing asthma trigger exposure in low-income children. Further research is needed to determine the effectiveness of specific interventions and structural improvements on asthma trigger exposure and health.
