Although African-Americans (Blacks) smoke fewer cigarettes per day than European-Americans (Whites), there is ample evidence that Blacks are more susceptible to smoking-related health consequences. A variety of behavioural, social and biological factors have been linked to this increased risk. There has been little research, however, on racial differences in smoking-related knowledge and perceived risk of lung cancer. The primary goal of the current study was to evaluate beliefs and knowledge that contribute to race disparities in lung cancer risk among current smokers. Data from two separate nationally representative surveys (the Health Information National Trends surveys 2003 and 2005) were analysed. Logistic and hierarchical regressions were conducted; gender, age, education level, annual household income and amount of smoking were included as covariates. In both studies, Black smokers were significantly more likely to endorse inaccurate statements than were White smokers, and did not estimate their lung cancer risk to be significantly higher than Whites. Results highlight an important racial disparity in public health knowledge among current smokers.
尽管非裔美国人（黑人）每天吸烟的数量比欧裔美国人（白人）少，但有充分的证据表明，黑人更容易受到与吸烟有关的健康后果的影响。各种行为、社会和生物因素都与这种风险增加有关。然而，关于与吸烟有关的知识和肺癌风险感知方面的种族差异的研究很少。目前研究的主要目标是评估导致当前吸烟者肺癌风险种族差异的信念和知识。对来自两个独立的全国代表性调查（2003 年和 2005 年的国家健康信息趋势调查）的数据进行了分析。进行了逻辑和层次回归分析；性别、年龄、教育水平、家庭年收入和吸烟量作为协变量。在两项研究中，黑人吸烟者比白人吸烟者更有可能认可不准确的说法，而且他们并不认为自己的肺癌风险比白人高很多。研究结果突出了当前吸烟者在公共卫生知识方面存在重要的种族差异。
