Colorectal cancer (CRC) screening has been found to be an effective tool for the control and prevention of this type of cancer, yet it is underutilized by African Americans. Consequently, African Americans with CRC are diagnosed at late stages and suffer disproportionately higher mortality rates for CRC.
To understand factors that influence the decision to participate in CRC screening, in-depth personal interviews were conducted with 36 African Americans in the Washington, DC, metropolitan area. Predisposing factors, enabling factors, and reinforcing factors were identified and categorized using the Predisposing, Reinforcing, and Enabling Constructs in Educational/Environmental Diagnosis and Evaluation (PRECEDE) framework.
Findings suggest that distinct differences exist between individuals who are adherent to screening guidelines and those who have not undergone screening. Adherent individuals were more knowledgeable about CRC and held positive beliefs about the benefits of screening. Nonadherent individuals placed little importance on prevention and early detection. Physician recommendation and insurance coverage/cost also differentiated the two groups.
Study findings suggest that efforts to increase awareness and promote the benefits of CRC screening are needed among African Americans. Also, efforts by healthcare providers to recommend CRC screening are important in promoting adherence. Further, low- or no-cost CRC screening is needed to increase participation by individuals who are economically disadvantaged.
结直肠癌(CRC)筛查已被证明是控制和预防这类癌症的有效工具,但非裔美国人对其利用不足。因此,患有结直肠癌的非裔美国人在晚期才被诊断出来,并且因结直肠癌导致的死亡率高得不成比例。
为了解影响参与结直肠癌筛查决策的因素,对华盛顿特区都会区的36名非裔美国人进行了深入的个人访谈。使用教育/环境诊断与评估中的诱发因素、强化因素和促成因素(PRECEDE)框架来识别和分类诱发因素、促成因素和强化因素。
研究结果表明,坚持筛查指南的个体与未接受筛查的个体之间存在明显差异。坚持筛查的个体对结直肠癌了解更多,并且对筛查的益处持有积极的信念。不坚持筛查的个体对预防和早期检测不太重视。医生的建议以及保险覆盖范围/费用也使两组有所区别。
研究结果表明,需要在非裔美国人中提高对结直肠癌筛查的认识并宣传其益处。此外,医疗保健提供者推荐结直肠癌筛查的努力对于促进坚持筛查很重要。此外,需要提供低成本或免费的结直肠癌筛查,以提高经济上处于不利地位的个体的参与度。
