Individuals experiencing homelessness smoke cigarettes at high rates, suffer a disproportionate incidence of lung cancer, but are unlikely to be screened to enhance early detection. Understanding correlates of lung cancer screening (LCS) interest within this vulnerable group may lend insight into prevention and treatment efforts and reduce their smoking-related morbidity and mortality. This study sought to understand how risk perception and interest in quitting smoking relate to LCS interest among homeless adults. Participants comprised a convenience sample of CO-verified current smokers ( = 310; 72.6% men, M = 43 + 11.7) from a homeless shelter in Dallas, TX. Participants self-reported risk perception, interest in quitting smoking, and interest in LCS. The average risk perception was 6.7 + 3.2 (range 0-10), 74.8% ( = 232) agreed or strongly agreed with interest in LCS, and 65.8% ( = 204) were interested in quitting smoking. Greater interest in quitting smoking, but not greater risk perception, was associated with greater interest in LCS (adjusted OR: 1.968, (95% CI: 1.213, 3.191), = 0.006). Risk perception and interest in quitting smoking did not interact in their association with interest in LCS. Results suggest that homeless smokers with an interest in quitting may be receptive to LCS: a diagnostic tool by which cancers can be caught at earlier stages and prior to metastasis. However, few in the current sample would be eligible for LCS based on current guidelines; results have implications for altered screening practices among chronic smokers experiencing homelessness.
无家可归者吸烟率很高，患肺癌的比例不成比例，但不太可能接受筛查以提高早期发现率。了解这一弱势群体中肺癌筛查（LCS）的相关性可能有助于预防和治疗，并降低他们与吸烟相关的发病率和死亡率。本研究旨在了解风险感知和戒烟意愿如何与无家可归的成年人的 LCS 意愿相关。参与者是来自德克萨斯州达拉斯市一个无家可归者收容所的 CO 验证的当前吸烟者（=310；72.6%为男性，M=43+11.7）的便利样本。参与者自我报告了风险感知、戒烟意愿和 LCS 意愿。平均风险感知为 6.7+3.2（范围 0-10），74.8%（=232）同意或强烈同意进行 LCS，65.8%（=204）对戒烟感兴趣。对戒烟更感兴趣，而不是对风险感知更感兴趣，与对 LCS 更感兴趣相关（调整后的 OR：1.968，（95% CI：1.213，3.191），=0.006）。风险感知和戒烟意愿在与 LCS 意愿的关联中没有相互作用。结果表明，有戒烟意愿的无家可归吸烟者可能会接受 LCS：这是一种诊断工具，可以在癌症转移之前更早地发现癌症。然而，根据目前的指南，当前样本中很少有人有资格进行 LCS；研究结果对改变无家可归的慢性吸烟者的筛查实践具有影响。
