ABSTRACT The diversity among Hispanics/Latinos, defined by geographic origin (e.g., Mexico, Puerto Rico, Cuba), has been neglected when assessing cancer morbidity. For the first time in the United States, we estimated cancer rates for Cubans, Mexicans, Puerto Ricans, and other Latinos, and analyzed changes in cancer risk between Hispanics in their countries of origin, U.S. Hispanics in Florida, and non-Hispanic Whites in Florida.
Florida cancer registry (1999-2001) and the 2000 U.S. Census population data were used. The Hispanic Origin Identification Algorithm was applied to establish Hispanic ethnicity and subpopulation.
The cancer rate of 537/100,000 person-years (95% confidence interval, 522.5-552.5) for Hispanic males in Florida was lower than Whites (601; 595.4-606.9). Among women, these rates were 376 (365.6-387.1) and 460 (455.6-465.4), respectively. Among Florida Hispanics, Puerto Ricans had the highest rates, followed by Cubans. Mexicans had the lowest rates. Rates for Hispanics in Florida were at least 40% higher than Hispanics in their countries of origin, as reported by the IARC.
Substantial variability in cancer rates occurs among Hispanic subpopulations. Cubans, unlike other Hispanics, were comparable with Whites, especially for low rates of cervical and stomach cancers. Despite being overwhelmingly first generation in the U.S. mainland, Puerto Ricans and Cubans in Florida showed rates of colorectal, endometrial, and prostate cancers similar to Whites in Florida. Because rates are markedly lower in their countries of origin, the increased risk for cancer among Cubans, Mexicans, and Puerto Ricans who move to the United States should be further studied.

    ABSTRACT: Guided by the theory of planned behavior, this study utilized data from the 2008 wave of the Health and Retirement Study to investigate psychosocial factors associated with older Hispanic women's participation in breast cancer screening services. Hierarchical logistic regression models were used to assess the odds of breast cancer screening participation. Findings indicate that satisfaction with aging and constraints were associated with a reduced likelihood of participating in breast cancer screening. These findings suggest the continued importance to assess older women's attitudes when discussing preventive services.

    ABSTRACT: Interpersonal violence research on Latinos has largely ignored the ethnic group variations that are included under the pan-ethnic term Latino. The current study adds to the literature by utilizing a national sample of Latino women to examine the interpersonal victimization experiences and help-seeking responses to victimization by ethnic group. The sample was drawn from the Sexual Assault Among Latinas Study (SALAS; Cuevas & Sabina, 2010) that surveyed 2,000 self-identified adult Latino women. For the purpose of this study, victimization in the United States was examined among Mexican ethnics (73.3% of sample), Cuban ethnics (14%), and other ethnics (12.8%). Mexican ethnicity was found to be significantly associated with increased odds of experiencing any, physical, sexual, threat, and stalking victimization. Findings also show that higher levels of Latino orientation and being an immigrant were associated with decreased odds of experiencing any victimization, whereas Anglo orientation, as measured by the Brief ARSMA-II (Cuéllar, Arnold, & Maldonado, 1995), was associated with greater odds of experiencing any victimization. Anglo orientation was significantly associated with formal help seeking. Taken as a whole, these findings emphasize the importance of bilingual and culturally competent services and also reveal that culturally competent services includes developing an understanding of the cultural differences between Latino ethnic groups. Specifically, service providers should be aware that Latinos of Mexican ethnicity may face unique risks for victimization. (PsycINFO Database Record (c) 2014 APA, all rights reserved).
