Low-dose computed tomography lung cancer (LDCT) screening is an effective way to decrease lung cancer mortality. Both Medicare and private insurers offer coverage of LDCT screening to beneficiaries who are at high risk of developing lung cancer. In this study, we examined rates and predictors of chronic smoking behavior and eligibility for coverage of LDCT screening among older Chinese men living in the greater Chicago area.
Data were obtained from the Population Study of Chinese Elderly in Chicago, a population-based survey of community-dwelling, older Chinese adults in the Chicago metropolitan area. Eligibility criteria according to Centers of Medicare and Medicaid Services (CMS) and U.S. Preventive Services Task Force (USPSTF) for LDCT screening were used. Multivariate logistic regression was conducted to determine predictors of chronic smoking behavior which was operationalized as meeting criteria for LDCT screening.
A quarter of the sample were current smokers and 42.5% reported a prior history of smoking. Eighteen percent and 22% of older Chinese men met the eligibility criteria for appropriateness for CMS and USPSTF LDCT screening, respectively. Furthermore, education, marital status, and number of children were significantly associated with chronic smoking behavior.
Older Chinese men with chronic smoking behavior are at high risk of developing lung cancer and nearly one in five meet eligibility for LDCT screening. Increased outreach and education regarding early detection of lung cancer and smoking cessation are needed for this vulnerable and high-risk population.
低剂量计算机断层扫描肺癌(LDCT)筛查是降低肺癌死亡率的有效方法。医疗保险和私人保险公司都为罹患肺癌风险高的受益人提供LDCT筛查服务。在本研究中,我们调查了居住在大芝加哥地区的老年中国男性的慢性吸烟行为发生率和预测因素,以及LDCT筛查的覆盖资格。
数据来自芝加哥华人老年人队列研究,这是一项对芝加哥大都市地区居住在社区的老年华人成年人进行的基于人群的调查。采用了医疗保险和医疗补助服务中心(CMS)及美国预防服务工作组(USPSTF)关于LDCT筛查的资格标准。进行多因素逻辑回归以确定慢性吸烟行为的预测因素,慢性吸烟行为定义为符合LDCT筛查标准。
四分之一的样本为当前吸烟者,42.5%报告有吸烟史。分别有18%和22%的老年中国男性符合CMS和USPSTF的LDCT筛查适宜性资格标准。此外,教育程度、婚姻状况和子女数量与慢性吸烟行为显著相关。
有慢性吸烟行为的老年中国男性罹患肺癌的风险很高,近五分之一符合LDCT筛查资格。对于这个脆弱的高危人群,需要加强关于肺癌早期检测和戒烟的宣传及教育。
