Cancer screening is important for health promotion and is a key element in reducing the disparities in cancer morbidity and mortality. Mortality rates for colorectal cancer are more than 40% higher among African Americans than among other ethnic populations in the United States. The primary objective of the present study is to determine correlates of colonoscopy utilization in the Black Women's Health Study. Our study sample comprised 10992 black women from the Black Women's Health Study whose ages ranged from 50 to 72 years at baseline in 1997; colonoscopy use in the subsequent 8 years was ascertained. The strongest correlate of colonoscopy use was mammography use: women who utilized mammography had 2.5 times the odds of having a colonoscopy, compared with those who never screened for breast cancer. Women who reported having health insurance had 2 times the odds of having a colonoscopy compared with women who did not have health insurance. Higher level of education was also associated with colonoscopy screening. Concurrent promotion of cancer screenings, ie, mammography and colonoscopy, may be a good approach to increasing colonoscopy utilization among women.
癌症筛查对促进健康很重要，也是降低癌症发病率和死亡率差异的关键因素。在美国，非裔美国人的结直肠癌死亡率比其他族裔高出 40%以上。本研究的主要目的是确定黑人妇女健康研究中结肠镜检查利用的相关因素。我们的研究样本包括来自黑人妇女健康研究的 10992 名黑人妇女，她们在 1997 年基线时的年龄在 50 至 72 岁之间；在随后的 8 年内确定了结肠镜检查的使用情况。结肠镜检查利用的最强相关因素是乳房 X 线照相术的使用：与从未进行过乳腺癌筛查的女性相比，使用乳房 X 线照相术的女性进行结肠镜检查的几率是其 2.5 倍。与没有医疗保险的女性相比，报告有医疗保险的女性进行结肠镜检查的几率是其 2 倍。受教育程度较高也与结肠镜检查筛查相关。同时促进癌症筛查，即乳房 X 线照相术和结肠镜检查，可能是增加女性结肠镜检查利用率的一种很好的方法。
