Special Populations

    Similar studies of Hispanic populations have been conducted. Breast cancer stage at diagnosis in San Diego County, California, was more advanced for Hispanic women than for white women, especially for those younger than 50 years. Low-income whites were more likely to have late-stage diagnosis than high-income whites. Among Hispanic women, there was no difference according to income, but all the Hispanic groups were at or below the lowest white income level.[11] In New Mexico, a population-based case-control study examined the reproductive histories of 719 Hispanic and 836 white breast cancer patients, with half of each group having breast cancer. The Hispanic women had higher body mass index, higher parity, and earlier pregnancies.[12] Whereas reproductive factors such as age at first full-term birth, parity, and duration of lactation accounted for some of the ethnic differences in breast cancer incidence for postmenopausal women, there was no evidence that these factors played a role in the differences for premenopausal patients. A study of mammography screening in an Albuquerque health maintenance organization found that Hispanic women had consistently lower rates of screening than did whites (50.6% vs. 65.5% in 1989, and 62.7% vs. 71.6% in 1996).[13] Predictors of more advanced stage at diagnosis included Hispanic race (odds ratio, 2.12) and younger age.
