Racial disparities in lung cancer have been described well in the literature; however, little is known about perceptions of lung cancer in the general population and whether these perceptions differ by race.
Data were obtained from the 2005 Health Information National Trends Survey (HINTS) survey. The authors used a sample design of random digit dialing of listed telephone exchanges in the United States. Complete interviews were conducted with 5491 adults, including 1872 respondents who were assigned to receive questions pertaining to lung cancer. All analyses were conducted on this subset of respondents. A statistical software program was used to calculate chi-square tests and to perform logistic regression analyses that would model racial differences in perceptions of lung cancer. All estimates were weighted to be nationally representative of the US population; a jack-knife weighting method was used for parameter estimation.
Black patients and white patients shared many of the same beliefs about lung cancer mortality, and etiology. African Americans were more likely than whites 1) to agree that it is hard to follow recommendations about preventing lung cancer (odds ratio [OR], 2.05; 95% confidence interval [CI], 1.19-3.53), 2) to avoid an evaluation for lung cancer for fear that they have the disease (OR, 3.32; 95% CI, 1.84-5.98), and 3) to believe that patients with lung cancer would have pain or other symptoms before diagnosis (OR, 2.20; 95% CI, 1.27-3.79).
African Americans were more likely to hold beliefs about lung cancer that could interfere with prevention and treatment.
肺癌的种族差异在文献中已有详细描述；然而，人们对普通人群中对肺癌的看法知之甚少，也不知道这些看法是否因种族而异。
数据来自 2005 年健康信息国家趋势调查（HINTS）调查。作者采用了美国列出的电话交换局随机数字拨号的样本设计。对 5491 名成年人进行了完整的访谈，其中包括 1872 名被分配接受与肺癌相关问题的受访者。所有分析均针对这部分受访者进行。使用统计软件程序计算卡方检验，并进行逻辑回归分析，以模拟对肺癌看法的种族差异。所有估计值均经过加权处理，以代表美国人口的全国代表性；使用刀叉加权法进行参数估计。
黑人和白人患者对肺癌死亡率和病因有许多相同的看法。与白人相比，非裔美国人更有可能：1）同意很难遵循预防肺癌的建议（优势比 [OR]，2.05；95%置信区间 [CI]，1.19-3.53），2）担心患有肺癌而避免进行肺癌评估（OR，3.32；95% CI，1.84-5.98），3）认为肺癌患者在诊断前会有疼痛或其他症状（OR，2.20；95% CI，1.27-3.79）。
非裔美国人更有可能持有可能妨碍预防和治疗的肺癌看法。
