The health of Latino children: urgent priorities, unanswered questions, and a research agenda.

Latinos recently became the largest racial/ethnic minority group of US children. The Latino Consortium of the American Academy of Pediatrics Center for Child Health Research, consisting of 13 expert panelists, identified the most important urgent priorities and unanswered questions in Latino child health. Conclusions were drawn when consensus was reached among members, with refinement through multiple iterations. A consensus statement with supporting references was drafted and revised. This article summarizes the key issues, including lack of validated research instruments, frequent unjustified exclusion from studies, and failure to analyze data by pertinent subgroups. Latino children are at high risk for behavioral and developmental disorders, and there are many unanswered questions about their mental health needs and use of services. The prevalence of dental caries is disproportionately higher for Latino children, but the reasons for this disparity are unclear. Culture and language can profoundly affect Latino children's health, but not enough cultural competency training of health care professionals and provision of linguistically appropriate care occur. Latinos are underrepresented at every level of the health care professions. Latino children are at high risk for school dropout, environmental hazards, obesity, diabetes mellitus, asthma, lack of health insurance, nonfinancial barriers to health care access, and impaired quality of care, but many key questions in these areas remain unanswered. This article suggests areas in which more research is needed and ways to improve research and care of Latino children.

Improving breast cancer control among Latinas: evaluation of a theory-based educational program.

The study evaluated a theory-based breast cancer control program specially developed for less acculturated Latinas. The authors used a quasi-experimental design with random assignment of Latinas into experimental (n = 51) or control (n = 37) groups that completed one pretest and two posttest surveys. The experimental group received the educational program, which was based on Bandura's self-efficacy theory and Freire's empowerment pedagogy. Outcome measures included knowledge, perceived self-efficacy, attitudes, breast self-examination (BSE) skills, and mammogram use. At posttest 1, controlling for pretest scores, the experimental group was significantly more likely than the control group to have more medically recognized knowledge (sum of square [SS] = 17.0, F = 6.58, p < .01), have less medically recognized knowledge (SS = 128.8, F = 39.24, p < .001), greater sense of perceived self-efficacy (SS = 316.5, F = 9.63, p < .01), and greater adeptness in the conduct of BSE (SS = 234.8, F = 153.33, p < .001). Cancer control programs designed for less acculturated women should use informal and interactive educational methods that incorporate skill-enhancing and empowering techniques.

From ethnography to intervention: developing a breast cancer control program for Latinas.

Latinas are less likely than Anglo women to have appropriate breast cancer screening for reasons that may include culturally based beliefs as well as socioeconomic factors. This study employed ethnographic methods to explore breast cancer-related knowledge, attitudes, and behaviors among Latinas, Anglo women, and physicians, tested the generalizability of the findings in a telephone survey of randomly selected women, and used the results to design a culturally sensitive breast cancer control intervention in Orange County, Calif. Respondents for the ethnographic interviews included 28 Salvadoran immigrants, 39 Mexican immigrants, 27 Chicanas (U.S.-born Latinas of Mexican heritage), 27 Anglo women, and 30 physicians selected through organization-based network sampling. Latinas had very different beliefs about risk factors for breast cancer and held more fatalistic attitudes about the disease. For example, they believed that trauma to the breast was among the most important risk factors. Results of a telephone survey of 1225 randomly selected women (269 U.S.-born Latinas, 425 Mexican immigrants, 109 other Latina immigrants, and 422 Anglo women) generally confirmed the dissimilar beliefs among Latinas and Anglo women. The findings influenced our decision to design and pilot-test a breast cancer control intervention based on Bandura's self-efficacy theory and Freire's empowerment pedagogy. The methodology and findings of this study have important implications for future cancer control research and interventions.

Epidemiology of cancer among Hispanics in the United States.

BACKGROUND: There are very limited data on cancer among U.S. Hispanics. The data that are available seldom appear outside individual registry reports. Without coalescing and assessing such information, the epidemiology of cancer among Hispanics cannot be understood. PURPOSE: This article presents an overall view of the epidemiology of cancer among Hispanic populations in the United States. METHODS: Major types of cancer were reviewed from geographic areas with 1) large Hispanic/Latino populations and 2) population-based cancer registries that cover 68% of the U.S. Hispanic population. Age-standardized rates, standardized rate ratios, and ranks of the top cancers are presented for Hispanics and non-Hispanics by sex. RESULTS: Hispanic men had consistently lower rates of cancers of the lung, prostate, colon, rectum, and oral cavity as well as of melanoma and non-Hodgkin's lymphoma than non-Hispanic men. Among Hispanic men, higher rates were observed for cancers of the stomach, liver, and gallbladder. Compared with the rates in non-Hispanic women, Hispanic women had consistently lower rates of cancers of the breast, colon, rectum, endometrium, lung, ovary, and oral cavity, non-Hodgkin's lymphoma, and melanoma and higher rates of cancers of the uterine cervix, stomach, liver, and gallbladder. Perhaps more importantly, however, was that, within U.S. Hispanic populations, the top five sites of cancer for women were breast, colon, lung, cervix, and uterine corpus. For men, the top sites were usually prostate, lung, colon, stomach, and rectum. Furthermore, some geographic areas showed differences in the order of importance within these five sites, while in other areas, the top five cancers for Hispanic men included kidney and bladder cancers, liver cancer, and non-Hodgkin's lymphomas. For women, other leading cancers mentioned were ovarian cancer, non-Hodgkin's lymphoma, and gallbladder cancer. CONCLUSIONS: Hispanics had consistently lower rates of breast, lung, prostate, and colon cancers than non-Hispanics. In some geographic regions, however, differences in cancer incidence rates with respect to specific sites existed between the heterogenous Hispanic populations. Furthermore, the rankings demonstrated that, even if Hispanics have lower rates of the most common cancers than non-Hispanics, such sites are still the most important cancers among Hispanic populations. IMPLICATIONS: Cancer is a major problem among U.S. Hispanic populations. The information given in this article can be used to develop etiologic studies and cancer control interventions. Data limitations and recommendations for improving data quality are presented.

A review of instruments assessing public health preparedness.

OBJECTIVES: The purpose of this study was to review instruments that assess the level of preparedness of state and local public health departments to respond to health threats such as bioterrorism. METHODS: The authors examined 27 published population-based instruments for planning or evaluating preparedness that were mostly unavailable in the peer-reviewed literature. Using the Essential Public Health Services framework, the instruments were evaluated for (1) clarity of measurement parameters, (2) balance between structural and process measures, (3) evidence of effectiveness, and (4) specification of an accountable entity. RESULTS: There was a great deal of overlap but little consistency in what constitutes "preparedness" or how it should be measured. Most instruments relied excessively on subjective or structural measures, lacked scientific evidence for measures assessed, and failed to clearly define what entity was accountable for accomplishing the task or function. CONCLUSION: Strategies for improvement include measure standardization, better interagency communication, and investment in public health practice research to develop the underlying evidence base required for developing quality measures and assessments.
