The prevalence of cigarette smoking is higher among African Americans than among whites. African Americans have higher rates of lung cancer than whites, although they smoke fewer cigarettes. To explore this black-white difference in lung cancer rates, I examine various aspects of tobacco use in African-American smokers, including the age of initiation of smoking, quantity of cigarettes smoked, quit rates, level of nicotine dependence, biochemical differences, and brand preferences, specifically menthol brand cigarettes. I also review briefly the sequelae of patterns of tobacco use, including rates of lung and other tobacco-related cancers. A preference for mentholated cigarettes by African Americans is well documented and is one of the most striking differences between African-American and white smokers. Menthol brand preference has been investigated in an attempt to explain the black-white differences in rates of cancers of the lungs and the upper respiratory and digestive tracts. Also, studies have evaluated smoking behavior both with and without menthol and have explicitly examined the question of whether menthol use helps explain the black-white difference in lung cancer rates. The results of these studies are so far inconclusive with regard to the use of menthol and the risk of lung cancer developing. I provide practical suggestions for clinicians in counseling African-American smokers to quit smoking and to maintain a nonsmoking status.
非裔美国人中吸烟的流行率高于白人。非裔美国人的肺癌发病率高于白人,尽管他们吸烟较少。为了探究肺癌发病率方面的这种黑白差异,我研究了非裔美国吸烟者烟草使用的各个方面,包括开始吸烟的年龄、吸烟量、戒烟率、尼古丁依赖程度、生化差异以及品牌偏好,特别是薄荷醇品牌香烟。我还简要回顾了烟草使用模式的后果,包括肺癌及其他与烟草相关癌症的发病率。非裔美国人对薄荷醇香烟的偏好有充分记录,这是他们与白人吸烟者最显著的差异之一。对薄荷醇品牌偏好进行了研究,试图解释肺癌以及上呼吸道和消化道癌症发病率方面的黑白差异。此外,研究评估了有薄荷醇和无薄荷醇情况下的吸烟行为,并明确研究了薄荷醇的使用是否有助于解释肺癌发病率的黑白差异这一问题。就薄荷醇的使用与患肺癌风险而言,这些研究结果目前尚无定论。我为临床医生在为非裔美国吸烟者提供戒烟咨询及维持不吸烟状态方面提供实用建议。
