INTRODUCTION
American Indian and Alaska Native (AI/AN) women have among the lowest rates of colorectal cancer (CRC) screening. Whether screening disparities persist with equal access to health care is unknown.
METHODS
Using administrative data from 1996-2007, we compared CRC screening events for 286 AI/AN and 14,042 White women aged 50 years and older from a health maintenance organization in the Pacific Northwest of the U.S.
RESULTS
The proportion of AI/AN and White women screened for CRC at age 50 was similar (13.3% vs. 14.0%, p =.74). No differences were seen in the type of screening test. Time elapsed to first screening among AI/AN women who were not screened at age 50 did not differ from White women (hazard ratio 1.0, 95% confidence interval 0.8-1.3).
CONCLUSIONS
Uptake for CRC screening was similar among insured AI/AN and White women, suggesting that when access to care is equal, racial disparities in screening diminish.
引言
美国印第安人和阿拉斯加原住民（AI/AN）女性的结直肠癌（CRC）筛查率是最低的。在获得同等医疗保健服务的情况下，筛查差异是否依然存在尚不清楚。
方法
利用1996年至2007年的管理数据，我们比较了美国太平洋西北部一家健康维护组织中286名年龄在50岁及以上的AI/AN女性和14,042名白人女性的CRC筛查情况。
结果
50岁时接受CRC筛查的AI/AN女性和白人女性比例相似（13.3%对14.0%，p = 0.74）。筛查测试类型没有差异。50岁时未接受筛查的AI/AN女性首次筛查的时间与白人女性没有差异（风险比1.0，95%置信区间0.8 - 1.3）。
结论
参保的AI/AN女性和白人女性的CRC筛查接受率相似，这表明在获得同等医疗服务的情况下，筛查中的种族差异会减小。
