目的：大多数关于乳腺癌风险与社会经济地位（SES）的研究是针对黑人和白人进行的。本研究评估了加利福尼亚州四个种族/族裔群体中社会经济地位与乳腺癌发病率之间的关系。
方法：利用主成分分析，根据1990年人口普查数据创建一个社会经济地位指数。未追踪到的病例被随机分配到其居住县内的人口普查街区组。对1988年至1992年期间在加利福尼亚州确诊的共97227例女性乳腺癌病例进行了评估。估算了发病率和率比（RRs），并对社会经济地位各水平间的趋势进行了卡方检验。
结果：社会经济地位与乳腺癌发病率呈正相关，这种影响在西班牙裔和亚裔/其他族裔中比在白人和黑人中更强。通过社会经济地位进行调整并没有消除种族/族裔群体之间乳腺癌发病率的差异。种族/族裔群体之间的率比差异在社会经济地位最低类别中最大，并随着社会经济地位的提高而减弱。在所有种族/族裔群体中，随着社会经济地位升高的趋势具有统计学意义。纳入随机分配的病例仅影响白人女性的率比估算。
结论：我们的结果与洛杉矶地区的类似发现一致，但与旧金山湾区先前的结果不同。
Objective: The majority of research on breast cancer risk and socioeconomic status (SES) has been conducted for blacks and whites. This study evaluates the relationship between SES and breast cancer incidence in California for four race/ethnic groups.Methods: Principal component analysis was used to create an SES index using 1990 Census data. Untracted cases were randomly allocated to census block groups within their county of residence. A total of 97,227 female breast cancer cases diagnosed in California between 1988 and 1992 were evaluated. Incidence rates and rate ratios (RRs) were estimated and a chi (2) test for trend across SES levels was performed.Results: SES was positively related to breast cancer incidence, and this effect was stronger for Hispanics and Asian/others than for whites and blacks. Adjusting by SES did not eliminate the differences in breast cancer rates among race/ethnic groups. RR differences between the race/ethnic groups were greatest in the lowest SES category and attenuated with increasing SES. An increasing trend over SES was statistically significant for all race/ethnic groups. Including randomly allocated cases affected RR estimates for white women only.Conclusions: Our results are consistent with similar findings for the Los Angeles area but differ from previous results for the San Francisco Bay area.
