Little is known about the acceptability and use of remote biochemical verification of self-reported cessation among low-income and racially diverse smokers. We compared responses to an in-person carbon monoxide breath test and in-home urine cotinine test among 270 adults who reported 7-day continuous abstinence at 6-month follow-up in a community-based randomized cessation trial. Half of participants (50%) reported annual household income below $10,000, one in four (28%) had not completed high school, and 69% were Black or African American. Regardless of whether the two tests were offered separately, sequentially, or as a head-to-head choice, participants were more likely to accept an offer to take the urine test than the breath test (89% vs. 32%), and complete it (46% vs. 13%). The proportion of participants completing the urine test and returning a digital photo of the test result is comparable to several studies completed with less disadvantaged samples. Self-report was confirmed by urine test for 74% of participants with a conclusive test result, although a high percentage (39%) of test results were inconclusive. In-home urine testing appears both acceptable and feasible for many low-income smokers, but challenges with testing technology and response rates currently limit its value to increase confidence in self-reports.
对于低收入和种族多样的吸烟者自我报告戒烟的远程生化验证的可接受性和使用情况，人们了解甚少。在一项基于社区的随机戒烟试验中，我们比较了270名在6个月随访时报告连续7天戒烟的成年人对现场一氧化碳呼气测试和家庭尿液可替宁测试的反应。一半的参与者（50%）报告家庭年收入低于1万美元，四分之一（28%）未完成高中学业，69%为黑人或非裔美国人。无论这两种测试是单独提供、依次提供还是作为直接选择提供，参与者接受尿液测试的可能性都高于呼气测试（89%对32%），并且完成测试的可能性也更高（46%对13%）。完成尿液测试并返回测试结果数码照片的参与者比例与几项针对条件较好样本进行的研究相当。74%测试结果确凿的参与者通过尿液测试证实了自我报告，尽管有很高比例（39%）的测试结果不确定。对于许多低收入吸烟者来说，家庭尿液检测似乎是可接受且可行的，但测试技术和回复率方面的挑战目前限制了其在增强对自我报告信心方面的价值。
