    ABSTRACT: Hispanics are affected by many health care disparities. The National Cancer Institute (NCI), through its Special Populations Branch, is supporting networking and capacity-building activities designed to increase Hispanic participation and leadership in cancer research. Redes En Acción established a national network of cancer research centers, community-based organizations, and federal partners to facilitate opportunities for junior Hispanic scientists to participate in training and research projects on cancer control. Since 2000, Redes En Acción has established a network of more than 1800 Hispanic leaders involved in cancer research and education. The project has sustained 131 training positions and submitted 29 pilot projects to NCI for review, with 16 awards for a total of $800,000, plus an additional $8.8 million in competing grant funding based on pilot study results to date. Independent research has leveraged an additional $32 million in non-Redes funding, and together the national and regional network sites have participated in more than 1400 community and professional awareness events. In addition, the program conducted extensive national survey research that provided the basis for the Redes En Acción Latino Cancer Report, a national agenda on Hispanic cancer issues. Redes En Acción has increased participation in cancer control research, training, and awareness among Hispanic scientists and within Hispanic communities. Cancer 2006.

    ABSTRACT: Although cancer is a leading cause of morbidity and premature death among Latinos, there is limited knowledge of cancer-related issues and priorities of greatest significance to the Latino population, the largest minority group in the nation. This information is vital in helping to guide Latino cancer research, training, and awareness efforts at national, regional, and local levels. To help identify cancer issues of greatest relevance to Latinos, Redes En Accion, The National Hispanic/Latino Cancer Network, a major network among the National Cancer Institute's Special Populations Networks, conducted a survey of 624 key opinion leaders from around the country. Respondents were asked to rank the three cancer sites most important to Latinos in their region and the five issues of greatest significance for this population's cancer prevention and control. Recommendations were prioritized for three specific areas: 1) research, 2) training and/or professional education, and 3) awareness and/or public education. Among cancers, breast carcinoma was ranked number one, followed in order by cervical and lung carcinomas. The issues of greatest significance to Latinos were 1) access to cancer screening and care, 2) tobacco use, 3) patient-doctor communication, 4) nutrition, and 5) risk communication. This survey solicited information from scientists, health care professionals, leaders of government agencies, professional and community-based organizations, and other stakeholders in Latino health. The results laid the foundation for a national Redes En Accion Latino cancer agenda, thus providing a useful tool for individuals and organizations engaged in cancer prevention and control efforts among the Hispanic-Latino population.

    ABSTRACT: Personal health behaviors play a fundamental role in premature cancer morbidity and mortality. However, routine risk factor data on Latino groups are lacking. Knowledge of cancer risk prevalence by ethnoregional groups is particularly important for development of effective prevention and control strategies. Using the diverse populations and sites involved in the National Hispanic Leadership Initiative on Cancer (NHLIC): En Acción, this paper examines prevalence of six cancer risk factors among Mexican, Puerto Rican, Cuban, and Central American adult males in eight U.S. cities. Data were collected through two telephone surveys. The 1993-1994 sample consisted of 4170 males (2041 <40 years and 2120 > or =40 years). The 1997-1998 sample consisted of 4486 males (2286 <40 years and 2200 > or =40 years). Clear differences exist in risk factor prevalence among Latino subgroups. Overall, riskiest behaviors were found among Mexican American men in Texas, more of whom smoked, engaged in acute alcohol drinking, and had poorer diets and higher obesity levels than other Latino men. Root causes of these ethnoregional differences are likely due to both economic and cultural factors. Cancer prevention and control strategies and programs should be tailored to address specific needs of each population group.

    ABSTRACT: Little is known about prostate and colorectal cancer knowledge, attitudes, and screening practices among U.S. Latino men. Even less is known about the population's subgroup variations. This study assessed predictors of having obtained digital rectal examinations (DREs) among four Latino subgroups. Findings in this report are based on a cross-sectional telephone survey conducted between October 1993 and June 1994 as part of a multisite demonstration project for cancer prevention and control. The survey was conducted in eight U.S. cities identified via census data as having relatively high concentrations of targeted Latino subgroups. The analysis included 1499 Latino men aged > or = 40 who self-identified as Central American, Cuban American, Mexican American, or Puerto Rican. Overall, 53% of the sample reported ever having had a DRE and 68% reported ever having heard of the procedure. For all subgroups, the only significant predictor for obtaining a DRE was "ever heard of DRE." "Having your doctor discuss DRE" was a significant factor for Mexican Americans and Puerto Ricans. The lack of a universal DRE cancer-screening model among Latino groups highlights the need to address barriers in the context of the population's diversity. Ecologic approaches and clinician communication with Latinos need to be tailored to accommodate subgroup differences in knowledge, attitude, and practices related to DRE.

    ABSTRACT: This study sought to compare smoking behavior among Latino men and women from different countries of origin. A telephone-administered survey was conducted in 8 cities with Latino men and women of different national origin living in census tracts with at least 70% Latino individuals. A total of 8882 participants completed the survey; 53% were women. The average age of respondents was 44 years; 63% were foreign-born, and 59% preferred Spanish for the interview. Current smoking was more prevalent among men (25.0%, 95% confidence interval [CI] = 23.7, 26.3) than among women (12.1%, 95% CI = 11.1, 13.0). Smoking rates were not significantly different by national origin among men, but Puerto Rican women had higher rates of smoking than other women. Central American men and women had the lowest smoking rates. Foreign-born respondents were less likely to be smokers (odds ratio [OR] = 0.77, 95% CI = 0.66, 0.90) than US-born respondents, and respondents with 12 years or less of education had an increased odds of smoking (OR = 1.17, 95% CI = 1.01, 1.35). High ac culturation was associated with more smoking in women (OR = 1.12, 95% CI = 1.00-1.25) and less smoking in men (OR = 0.86, 95% CI = 0.78-0.95). Puerto Rican and Cuban respondents were more likely to be current smokers and to smoke more than 20 cigarettes per day. Older, US-born, and more-educated respondents were less likely to be current smokers. Respondents of Puerto Rican and Cuban origin were more likely to smoke. Acculturation has divergent effects on smoking behavior by sex.

    ABSTRACT: Although Hispanics' use of breast cancer screening services has been investigated, to date there have been no published studies of distinct Hispanic populations in different areas of the country. Using the diverse populations and sites involved in the National Hispanic Leadership Initiative on Cancer 'En Acción', this study examines ethno-regional differences in breast cancer screening rates among these groups and explores the correlates of screening participation. Data collected through telephone surveys were analyzed for women 40 years of age and older (n = 2082). After controlling for demographic variables traditionally related to breast cancer screening rates, it was found that ethno-regional differences in breast cancer screening practices clearly persisted. In addition to traditional demographic factors, other variables evidently underlie differences in Hispanics' utilization of breast cancer screening services. These variables may be cultural and should be investigated in future research. Meanwhile, researchers should not refer to the 'Hispanic' population at large without identifying, addressing and clarifying the ethno-regional characteristics of their samples.

    ABSTRACT: Evidence shows that social relationships play an important role in health and health behavior. We examined the relationship between social networks and cancer screening among four U.S. Hispanic groups. We used telephone surveys to collect data in eight U.S. regions that have concentrations of diverse Hispanic-origin populations. We interviewed 8903 Hispanic adults, for a response rate of 83%; analysis was restricted to the 2383 women aged > or =40. As a measure of social integration, we formed a social network index from items on the number of close relatives and friends, frequency of contact, and church membership. We used logistic regression to estimate the effects of social integration on screening, adjusting for sociodemographic factors. Among Mexican, Cuban, and Central-American women, the effect of social integration on mammography screening was slight. The odds ratios (OR) per unit change in social integration category ranged from 1.16 to 1.22 with confidence intervals (CI) that overlapped with the null. For Pap smear screening, the effect was strongest among Mexican-American women (OR=1.44, 95% CI=1.21 to 1.72), but also evident among Central-American women (OR=1.22, 95% CI=0.72 to 2.06) and Cuban women (OR = 1.25, 95% CI = 0.81 to 1.93). Among Puerto Rican women, social integration had no effect on either mammography (OR=1.03) or Pap smear screening (OR=1.08). Independent of socioeconomic factors, social integration appears to influence cancer screening participation of Hispanic women. The modest effect is not universal across Hispanic groups and was stronger for Pap smear than for mammography screening behavior. Researchers should recognize Hispanic group differences in social network characteristics and the potential of social networks to change screening behavior.
