OBJECTIVE: The majority of research on @entity0 risk and @entity159 ( @entity159 ) has been conducted for blacks and whites. This study evaluates the relationship between @entity159 and @entity0 incidence in @entity7452 for four race/ethnic groups. METHODS: Principal component analysis was used to create an @entity159 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 @entity0 cases diagnosed in @entity7452 between 1988 and 1992 were evaluated. Incidence rates and rate ratios (RRs) were estimated and a chi2 test for trend across @entity159 levels was performed. RESULTS: @entity159 was positively related to @entity0 incidence, and this effect was stronger for Hispanics and Asian/others than for whites and blacks. Adjusting by @entity159 did not eliminate the differences in @entity0 rates among race/ethnic groups. RR differences between the race/ethnic groups were greatest in the lowest @entity159 category and attenuated with increasing @entity159 . An increasing trend over @entity159 was statistically significant for all race/ethnic groups. Including randomly allocated cases affected RR estimates for white @entity1 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.
