简介烟草烟雾和氡气是肺癌的主要原因。 FRESH 干预是一项针对 515 名房主的随机对照试验，旨在促进降低氡气和空气尼古丁水平的行动阶段。方法我们研究了 515 名参与者，其中治疗组 257 名，对照组 258 名。治疗参与者获得了免费的氡气和空气尼古丁测试套件、报告和电话支持，而那些家中氡气水平较高的参与者则获得了 600 美元的缓解券。两组均被要求在干预后 15 个月重新进行测试。我们检查了测试和减轻氡气、采取无烟家庭政策的行动阶段以及各研究组观察到的氡气和空气尼古丁值随时间变化的差异。结果治疗组的房主在随访期间测试氡气和空气尼古丁和减轻氡气的行动阶段得分高于对照组，在第3个月和第9个月时，但干预效果在9个月后减弱。我们发现观察到的氡气或空气尼古丁值在各组之间或随着时间的推移没有差异。在基线时氡气水平较高的治疗组中，17% 的房主得到了缓解，其中 80% 使用了我们提供的代金券。 结论 从基线到 15 个月，观察到的氡气或空气尼古丁值没有显着变化这一无效发现可能反映了安装的氡气缓解系统比例较低以及采用无烟家庭政策的行动阶段的下降。在干预后 9 个月进行强化治疗可能会提高补救率。
IntroductionTobacco smoke and radon are the leading causes of lung cancer. The FRESH intervention was a randomized controlled trial of 515 homeowners to promote stage of action to reduce radon and air nicotine levels.MethodsWe studied 515 participants, 257 in a treatment group and 258 in a control group. Treatment participants received free radon and air nicotine test kits, report back, and telephone support, and those participants whose homes had high radon levels received a voucher for $600 toward mitigation. Both groups were asked to retest 15 months post intervention. We examined differences in stage of action to test for and mitigate radon and adopt a smoke-free-home policy and in observed radon and air nicotine values by study group over time.ResultsHomeowners in the treatment group scored higher on stage of action to test for radon and air nicotine and to mitigate for radon during follow-up than those in the control group at 3 months and 9 months, but the effect of the intervention diminished after 9 months. We saw no difference between groups or over time in observed radon or air nicotine values. Of homeowners in the treatment group with high radon levels at baseline, 17% mitigated, and 80% of them used the voucher we provided.ConclusionThe null finding of no significant change in observed radon or air nicotine values from baseline to 15 months may reflect the low proportion of radon mitigation systems installed and the decline in stage of action to adopt a smoke-free home policy. Including a booster session at 9 months post intervention may improve the remediation rate.
