Few studies have addressed the issue of whether delays in the interval between medical consultation and the diagnosis and treatment of breast carcinoma are greater for African American women than for white women. The authors examined differences with respect to these delays and analyzed the factors that may have contributed to such differences among women ages 20-54 years who had invasive breast carcinoma diagnosed between 1990 and 1992 and who lived in Atlanta, Georgia.
A total of 251 African American women and 580 white women were interviewed and had their medical records reviewed. The authors estimated racial differences in delay times and used polytomous logistic regression to determine the contributions of various factors (socioeconomic and other) to these differences.
Although most women in both groups were treated within 3 months of initial consultation, 22.4% of African American women and 14.3% of white women had clinical delays of > 3 months. Compared with white women, African American women were more likely to experience delays in diagnosis and treatment. Access to care (as represented by method of detection and insurance status) and poverty index partially accounted for these differences in delay time; however, racial differences in terms of delayed treatment and diagnosis remained even after adjustment for contributing factors.
The findings of the current study suggest that among women ages 20-54 years who have breast carcinoma, potentially clinically significant differences in terms of delayed diagnosis and treatment exist between African American women and white women. Improvements in access to care and in socioeconomic circumstances may address these differences to some degree, but additional research is needed to identify other contributing factors.
很少有研究探讨过非裔美国女性与白人女性相比,在乳腺癌医疗咨询与诊断及治疗之间的间隔时间延迟是否更长这一问题。作者对20 - 54岁、于1990年至1992年期间在佐治亚州亚特兰大被诊断为浸润性乳腺癌的女性中,这些延迟方面的差异进行了研究,并分析了可能导致此类差异的因素。
共对251名非裔美国女性和580名白人女性进行了访谈,并查阅了她们的病历。作者估计了延迟时间的种族差异,并使用多分类逻辑回归来确定各种因素(社会经济因素及其他因素)对这些差异的影响。
尽管两组中的大多数女性在初次咨询后的3个月内接受了治疗,但22.4%的非裔美国女性和14.3%的白人女性存在超过3个月的临床延迟。与白人女性相比,非裔美国女性在诊断和治疗方面更有可能出现延迟。获得医疗服务的情况(以检测方法和保险状况表示)以及贫困指数部分解释了延迟时间的这些差异;然而,即使在对影响因素进行调整之后,在延迟治疗和诊断方面的种族差异仍然存在。
当前研究的结果表明,在患有乳腺癌的20 - 54岁女性中,非裔美国女性与白人女性在延迟诊断和治疗方面可能存在具有潜在临床意义的差异。改善获得医疗服务的情况和社会经济状况可能在一定程度上解决这些差异,但还需要进一步研究以确定其他影响因素。
