目标.这项研究测试了教练的有效性，以减少环境烟草烟雾（ETS）暴露在哮喘拉丁美洲儿童。在哮喘管理教育后，家庭被随机分配到没有额外的服务（对照条件）或指导减少ETS暴露（实验条件）。这项研究是在加利福尼亚州的圣地亚哥进行的。204名患有哮喘的拉丁裔儿童（3-17岁）参与了研究。提供了大约1.5小时的哮喘管理教育;实验家庭还获得了7次指导课程（每次45分钟）以减少ETS暴露。报告ETS暴露和儿童的尿可替宁进行了测量。在教练条件下的父母报告说，他们的孩子接触到的香烟显着减少比控制儿童的父母4个月（教练后）。报告的患病率暴露儿童下降到52%的辅导家庭，但只有69%的控制。到第4个月，平均可替宁水平下降教练和控制儿童中增加。可替宁患病率从54%下降到40%的教练的家庭，而它从43%上升到49%的控制。然而，在13个月的随访中，对照组中的可替宁水平下降到与指导家庭相同的水平。哮喘管理教育加辅导可以减少ETS暴露超过预期的教育，并在辅导条件下的减少可能会持续约一年。讨论了可替宁在对照组中的延迟降低。
Objectives. This study tested the efficacy of coaching to reduce environmental tobacco smoke (ETS) exposure among asthmatic Latino children.Design. After asthma management education, families were randomly assigned to no additional service (control condition) or to coaching for ETS exposure reduction (experimental condition).Setting. The study was conducted in San Diego, California.Participants. Two hundred four Latino children (ages 3-17 years) with asthma participated.Intervention. Approximately 1.5 hours of asthma management education was provided; experimental families also obtained 7 coaching sessions (similar to45 minutes each) to reduce ETS exposure.Outcome Measures. Reported ETS exposure and children's urine cotinine were measured.Results. Parents in the coached condition reported their children exposed to significantly fewer cigarettes than parents of control children by 4 months (postcoaching). Reported prevalence of exposed children decreased to 52% for the coached families, but only to 69% for controls. By month 4, mean cotinine levels decreased among coached and increased among control children. Cotinine prevalence decreased from 54% to 40% among coached families, while it increased from 43% to 49% among controls. However, cotinine levels decreased among controls to the same level achieved by coached families by the 13-month follow-up.Conclusions. Asthma management education plus coaching can reduce ETS exposure more than expected from education alone, and decreases in the coached condition may be sustained for about a year. The delayed decrease in cotinine among controls is discussed.
