FRESH: Dual Home Screening for Lung Cancer Prevention

描述(由申请人提供)： 这项随机对照试验的目的是测试在家中免受氡暴露和吸烟(FRESH)的有效性，FRESH是一种双重家庭筛查和量身定制的环境反馈干预措施，旨在降低肺癌的环境风险，并确定与减少氡排放的金钱激励相关的因素。第一手烟雾、二手烟(SHS)和氡暴露的组合使患肺癌的风险增加近十倍。长期目标是通过减少家庭对氡和SHS的暴露来促进环境正义，并通过提供税收抵免的政策变化来促进减少氡的公平。一项招募了550名初级保健患者的随机对照试验将检验四个假设，控制年龄、性别、家庭吸烟和社会经济地位(SES)的背景因素：1)与对照组相比，接受Fresh治疗的患者将更有可能采取行动测试和减少氡，并制定和执行无烟家庭政策；2)与对照组相比，接受Fresh治疗的患者在干预后15个月将有更低的氡和家庭SHS水平；3)在干预15个月后，与对照组相比，接受Fresh治疗的患者患肺癌的感知风险和协同风险知觉(SHS X Ron)、与健康相关的自我概念、准备改变和预防肺癌的自我效能更高，肺癌担忧的减少更大；以及4)家中至少有一名吸烟者将不太可能采取行动减少氡和SHS的暴露。治疗组(n=275)将在初级保健诊所接受免费检测试剂盒，以测量其家庭基线时的氡和SHS，接收他们的检测结果和量身定制的环境反馈干预，并参加基线和干预后15个月的三次跟踪在线调查和家庭测试。那些氡含量高的人将获得费用的30%的代金券，最高可达600美元。控制组(n=275)将收到关于如何索取氡和SHS检测试剂盒的信息以及关于氡和SHS的小册子，并参加所有研究调查。干预15个月后，两组的参与者都将被要求测试他们的房屋是否有氡和SHS。项目 这项建议与公众健康直接相关，因为它有可能通过减少家庭中的氡和二手烟暴露来预防肺癌。

DESCRIPTION (provided by applicant): The purposes of this randomized controlled trial are to test the effectiveness of Freedom from Radon Exposure and Smoking in the Home (FRESH), a dual home screening and tailored environmental feedback intervention designed to reduce environmental risks for lung cancer, and to identify factors associated with monetary incentives for radon mitigation. The combination of firsthand smoke, secondhand smoke (SHS), and radon exposure increases the risk of lung cancer nearly tenfold. The long-term goals are to foster environmental justice by reducing home exposure to radon and SHS and to promote equity in radon mitigation by policy change to provide tax credits. A randomized controlled trial enrolling 550 primary care patients will test four hypotheses, controlling for contextual factors of age, gender, home smoking, and socioeconomic status (SES): 1) Those who receive FRESH will be more likely to take action to test and mitigate for radon and institute and enforce a smoke-free home policy compared to the control group; 2) Those receiving FRESH will have lower radon and home SHS levels at 15 months post-intervention compared to the control group; 3) Those who receive FRESH will have greater increases in perceived risk of lung cancer and synergistic risk perception (SHS x radon), health-related self-concept, readiness to change, and self-efficacy to prevent lung cancer, and a greater decrease in lung cancer worry compared to controls at 15 months post-intervention; and 4) Those with at least one smoker in the home will be less likely to take action to reduce exposure to radon and SHS. The Treatment group (n = 275) will receive free test kits in the primary care clinic to measure their homes for radon and SHS at baseline, receive their test results and the tailored environmental feedback intervention, and take part in baseline and three follow up online surveys and home testing 15 months post-intervention. Those with high radon will receive a voucher for 30% of the cost up to $600 for radon mitigation. The Control group (n = 275) will receive information on how to request test kits for radon and SHS and a brochure on radon and SHS, and take part in all study surveys. Participants in both groups will be asked to test their homes for radon and SHS 15 months post-intervention. Project The proposal is directly relevant to public health in that it has the potential to prevent lung cancer by reducing exposure to radon and secondhand smoke in the home.
