The lifetime risk of prostate cancer among African-American men is two times higher than that of white men. Mortality from the disease is almost three times greater in African-Americans than in whites. This study assesses the receptivity of older (fifty to seventy-four years of age) African-American men (n = 86) in Chicago to periodic (annual and semiannual) prostate cancer screening.
A telephone survey conducted in January and February 1993, was used to collect data on subject sociodemographic background and medical history and to gather information on knowledge, attitudes, and beliefs about prostate cancer and screening. Univariate and multivariate analyses were carried out to identify factors associated with subject receptivity to annual and semiannual screening.
Logistic regression analyses revealed that receptivity to annual and semiannual (every six months) examination is strongly associated with the degree to which screening is perceived as a salient and coherent (i.e., important, effective, and convenient) preventive health behavior. An additional factor independently associated with willingness to go through semiannual screening was subjects' awareness that African-American men are at increased risk for prostate cancer compared to white men.
Findings from this study suggest that African-American men are willing to undergo prostate screening and are more receptive to annual than semiannual screening. Participation in screening may be facilitated by the provision of health education messages that emphasize the salience and coherence of early detection and elevated population risk.
非裔美国男性患前列腺癌的终生风险是白人男性的两倍。该疾病导致的非裔美国人死亡率几乎是白人的三倍。本研究评估了芝加哥年龄较大（50至74岁）的非裔美国男性（n = 86）对定期（每年和每半年）前列腺癌筛查的接受程度。
1993年1月和2月进行了一项电话调查，用于收集受试者的社会人口背景和病史数据，并收集有关前列腺癌及筛查的知识、态度和信念方面的信息。进行单变量和多变量分析以确定与受试者接受每年和每半年筛查相关的因素。
逻辑回归分析显示，对每年和每半年检查的接受程度与筛查被视为一种突出且连贯（即重要、有效且方便）的预防性健康行为的程度密切相关。与愿意接受每半年筛查独立相关的另一个因素是受试者意识到与白人男性相比，非裔美国男性患前列腺癌的风险更高。
本研究结果表明，非裔美国男性愿意接受前列腺筛查，且对每年筛查的接受度高于每半年筛查。提供强调早期检测的突出性和连贯性以及人群风险升高的健康教育信息可能会促进筛查的参与。
