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.

The influence of knowledge and attitudes about breast cancer on mammography use among Latinas and Anglo women.

We conducted a telephone survey of randomly selected Latinas (n = 208) and Anglo women (n = 222) to determine predictors of mammography use. The cooperation rate was 78.5%. Relatively high proportions of Latinas (61%) and Anglo women (79%) reported mammography use within the past 2 years. A logistic regression analysis revealed that knowledge and attitudes did not independently predict use. On the other hand, having health insurance, being married, and being Latino were consistent independent predictors. We conclude that mammography use among Latinas and Anglo women is increasing. However, further gains in use must address difficult barriers such as lack of health insurance.

Purity and passion: risk and morality in Latina immigrants' and physicians' beliefs about cervical cancer.

This paper examines how physicians' beliefs about risk factors for cervical cancer compare with Mexican and Salvadoran immigrant women's views (hereafter Latina immigrants). Between August 15, 1991 and August 15, 1992, we conducted ethnographic interviews with 39 Mexican immigrant women, 28 Salvadoran immigrant women, and 30 physicians in northern Orange County, California. Physicians and Latina immigrants converge on their beliefs that sexual behavior is a predominant risk factor for cervical cancer. They diverge, however, on their reasons. Latina immigrants' perceptions of health risks are embedded in a larger set of cultural values centering around gender relations, sexuality, and morality. Latina immigrants also emphasized men's behavior as risk factors. Physicians' views, on the other hand, are largely based on the epidemiology of cervical cancer risk factors. They emphasized beginning sexual relations at an early age, multiple sexual partners, and infection with sexually transmitted viruses. Some physicians, however, displayed moral interpretations of the sex-based risk factors for cervical cancer through the use of the culturally-loaded term "promiscuous" in place of "multiple sexual partners," through specific references to morality, and through characterizations of women at risk for cervical cancer. Both the physicians and the Latina immigrants in our study paid considerably less attention to socioeconomic factors. Our results have important implications for physicians who provide health care for Latina immigrants. Physicians should be clear to point out that women need not be "promiscuous" to get cervical cancer.

Undocumented Latina immigrants in Orange County, California: a comparative analysis.

"This article examines a unique data set randomly collected from Latinas (including 160 undocumented immigrants) and non-Hispanic white women in Orange County, California, including undocumented and documented Latina immigrants, Latina citizens, and non-Hispanic white women. Our survey suggests that undocumented Latinas are younger than documented Latinas, and immigrant Latinas are generally younger than U.S.-citizen Latinas and Anglo women. Undocumented and documented Latinas work in menial service sector jobs, often in domestic services. Most do not have job-related benefits such as medical insurance.... Despite their immigration status, undocumented Latina immigrants often viewed themselves as part of a community in the United States, which significantly influenced their intentions to stay in the United States. Contrary to much of the recent public policy debate over immigration, we did not find that social services influenced Latina immigrants' intentions to stay in the United States."

Beliefs about sexual behavior and other predictors of Papanicolaou smear screening among Latinas and Anglo women.

BACKGROUND: Latinas use cervical cancer prevention services less often than Anglo women. OBJECTIVE: To assess whether beliefs about cervical cancer influence the use of Papanicolaou (Pap) smears among Latinas and Anglo women in Orange County, California. METHODS: We conducted a telephone survey using the computer-assisted telephone interview system, randomdigit dialing, and an instrument adapted from national surveys and a previous ethnographic study. RESULTS: Participants included 1225 noninstitutionalized Spanish- or English-speaking respondents 18 years or older-803 Latinas (533 immigrants and 270 US born) and 422 Anglo women. Latina immigrants were more likely than US-born Latinas or Anglo women to believe that a variety of behaviors were risk factors for this disease. These behaviors included medically accepted risk factors such as early initiation of sexual intercourse (53% vs 41% vs 39%; P < .01) as well as unaccepted factors such as having sex during menstruation (56% vs 10% vs 3%; P < .01). Logistic regression analysis revealed that Latinas who held such beliefs were significantly less likely than others to report receiving a Pap smear within the past 3 years. Other independent predictors of Pap smear use included health insurance status, martial status, and acculturation. CONCLUSIONS: Latinas have culturally based beliefs about cervical cancer that reflect the moral framework within which they interpret diseases and that may influence their use of Pap smears. These beliefs are most prevalent among Latina immigrants. Because the known risk factors for cervical cancer are primarily related to sexual activities and because such activities are private and sensitive for many Latinas, physicians should be cautious when counseling these patients about the cause of this disease. Indeed, stressing the sexual transmission of cervical cancer could even discourage Latina immigrants from obtaining appropriate Pap smear screening.

Knowledge, power and experience: variation in physicians' perceptions of breast cancer risk factors.

Recent theory in anthropology has increasingly been concerned with issues of power. Anthropology also has a long history of interest in variation in cultural knowledge, which, we argue, benefits from attention to power relations. To show this, we examine perceptions of breast cancer risk factors among physicians. Although physicians share a general cultural model of breast cancer risk factors, variation exists, especially between university-based physicians and community-based physicians. The nature of the work performed in these two settings influences the acquisition of various sources of information and frames what is considered valid information. Similar to Foucault's argument, we find that physicians working in a university setting are more disciplined in discussing their perceptions of breast cancer risk factors, compared to community-based physicians, who move away from the centers of knowledge and power (universities).

Differing beliefs about breast cancer among Latinas and Anglo women.

To improve breast cancer control among Latinas, it is important to understand culturally based beliefs that many influence the way women view this disease. We did a telephone survey of randomly selected Latinas and non-Hispanic white (Anglo) women in Orange County, California, to explore such beliefs using questions from previous national surveys and an ethnographic study of breast cancer. Respondents included 803 Latinas and 422 Anglo women. Latinas were more likely than Anglo women to believe that factors such as breast trauma (71% versus 39%) and breast fondling (27% versus 6%) increased the risk of breast cancer, less likely to know that symptoms such as breast lumps (89% versus 98%) and bloody breast discharge (69% versus 88%) could indicate breast cancer, and more likely to believe that mammograms were necessary only to evaluate breast lumps (35% versus 11%) (P < .01 for each). After adjusting for age, education, employment status, insurance status, and income, logistic regression analysis confirmed that Latino ethnicity and acculturation levels were significant predictors of these beliefs. We conclude that Latinas' beliefs about cancer differ in important ways from those of Anglo women and that these beliefs may reflect the moral framework within which Latinas interpret diseases. These findings are important for the development of culturally sensitive breast cancer control programs and for practicing physicians.

Understanding knowledge and attitudes about breast cancer. A cultural analysis.

OBJECTIVE: To evaluate knowledge and attitudes about breast cancer risk factors among Latinas, Anglo-American women, and physicians. DESIGN: Ethnographic interviews employing systematic data collection methods. PARTICIPANTS: Twenty-eight Salvadoran immigrants, 39 Mexican immigrants, 27 Chicanas, and 27 Anglo-American women selected through an organization-based network sampling and a convenience sample of 30 primary care physicians in Orange County, Calif. MAIN OUTCOME MEASURES AND RESULTS: Data analysis using qualitative content analysis and quantitative cultural consensus analysis, a mathematical technique that determines the degree of shared knowledge within groups and estimates "culturally correct" answers (cultural models), was employed. The content analysis revealed different beliefs about breast cancer risk factors, particularly between the Latinas and the physicians. The cultural consensus analysis found two broad cultural models (defined as groups with ratios between the first and second eigenvalues of > or = 3 and no negative competency scores). A Latina model (ratio = 3.4), formed by the Salvadorans, Mexicans, and Chicanas, emphasized breast trauma and "bad" behaviors, including drinking alcohol and using illegal drugs as risk factors. A biomedical model (ratio = 3.0), embraced by physicians and Anglo-American women, emphasized risk factors described in the medical literature, such as family history and age. Within these broad models, each group of respondents also differed enough in their beliefs to form their own, often stronger, cultural models. CONCLUSIONS: Ethnography can provide important insights about culturally based knowledge and attitudes about disease. An understanding of the distinctive cultural models regarding breast cancer risk factors will aid future cancer control interventions.

Structure and meaning in models of breast and cervical cancer risk factors: a comparison of perceptions among Latinas, Anglo women, and physicians.

This article reports on a study of perceptions of breast and cervical cancer risk factors among 27 U.S.-born Chicanas, 39 Mexican and 28 Salvadoran immigrants, 27 Anglo women, and 30 physicians in northern Orange County, California. In open-ended responses explaining why women might be at risk for both cancers, Latinas expressed two general themes: physical stress and trauma to the body, and behavior and lifestyle choices. Interviewees ranked the specific risk factors that they themselves mentioned. Cultural consensus of ranked data revealed that Mexican and Salvadoran immigrants had a model of cancer risks that was different from those of Anglo women and physicians. U.S.-born Chicanas were bicultural in their views, which overlapped with both Mexican women's and Anglo women's views, but less so with physicians' views. Comparing views about the two cancers revealed that general themes apply across both cancers, that Latina immigrants agreed less on the risk factors for cervical cancer than for breast cancer, and that there is a consistent pattern in the different ways Latinas, Anglos, and physicians perceive risk factors for both cancers.

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.

Access to medical care for documented and undocumented Latinos in a southern California county.

To determine local access to medical care among Latinos, we conducted telephone interviews with residents of Orange County, California. The survey replicated on a local level the national access surveys sponsored by the Robert Wood Johnson Foundation. We compared access among Latino citizens of the United States (including permanent legal residents), undocumented Latinos, and Anglos, and analyzed predictors of access. Among the sample of 958 respondents were 137 Latino citizens, 54 undocumented Latinos, and 680 Anglos. Compared with Anglos, Latino citizens and undocumented immigrants had less access to medical care by all measures used in the survey. Although undocumented Latinos were less likely than Latino citizens to have health insurance, by most other measures their access did not differ significantly. By multivariate analysis, health insurance status and not ethnicity was the most important predictor of access. Because access to medical care is limited for both Latino citizens and undocumented immigrants, policy proposals to improve access for Latinos should consider current barriers faced by these groups and local differences in access to medical care.

Utilization of health services by Mexican immigrant women in San Diego.

The limited empirical data available on maternal health problems among Mexican immigrant women in the United States suggest that they underutilize health services, especially general preventive care. Research conducted among legal and undocumented women in the Mexican immigrant population in San Diego, California, support these findings. Among undocumented mothers, 11.5% of their births in the U.S. occurred with no prenatal care or care sought in the third trimester, which is much higher than Mexican women legally in the country (3.6%) and the general San Diego maternal population (3.8%). When we examine births which occurred within the last five years by immigration status, we find that women legally in the country have a much higher rate of cesarean delivery of both undocumented women and women in the general San Diego maternal population. Undocumented women in our sample were much less likely than their legal counterparts to return for postpartum examinations for themselves, to seek neonatal care for their infants, and to have had Pap examinations or carry out breast self-examinations.

Mexican immigration and health care: a political economy perspective.

This paper examines the case of Mexican immigrants in the United States and their access to medical services within a political economy of health framework. Such an approach stresses that the provision of health care is independent of health factors per se and that access to health care is not equally distributed throughout a population. The first section reviews the three major concepts influencing medical anthropologists working within a political economy framework: the social origins of illness; the allocation of health resources; and fieldwork in Third World countries. The analysis then focuses upon the reasons for limiting immigrants' access to health care, followed by an examination of the socioeconomic characteristics of Mexican immigrants, including an undocumented immigration status, which limit their access to health care. Finally, the consequences of limited access to health services are suggested, including a low utilization of preventive health services resulting from the high cost of care combined with the immigrants' generally low income, lack of medical insurance and fear of using U.S. health services.

Mexican immigrants and the utilization of U.S. health services: the case of San Diego.

This paper examines survey data gathered from 2103 Mexican immigrants living or working in San Diego County, California, in order to explore four fundamental questions concerning the utilization of health services: (a) What type of health services do Mexican immigrants use? (b) When hospitals are used, do they tend to be emergency room services? (c) Do Mexican immigrants use preventive services? (d) To what extent do the utilization patterns of undocumented immigrants differ from their legally-immigrated counterparts? The socioeconomic profile of the sample is characterized through analysis of variables such as sex, age, length of residence in the U.S., occupation and income. Mexican immigrants, particularly the undocumented, are relatively young compared to the non-immigrant population, of short duration in the U.S. and earn low income. In addition, undocumented and legally-immigrated respondents are covered by medical insurance at rates far below the general population. Mexican immigrants, including the undocumented, use a variety of health services. Hospital services are not the primary source of care. However, when undocumented respondents did use hospital services, they were more likely to use emergency room care than their legally-immigrated counterparts, who were more likely to use out-patient services. Finally, undocumented respondents tended to neglect preventive services as evidenced by examination of the use of pre-natal care, general check-ups and dental services.

Health care use among undocumented Latino immigrants.

Using data from a 1996/1997 survey of undocumented Latino immigrants in four sites, we examine reasons for coming to the United States, use of health care services, and participation in government programs. We find that undocumented Latinos come to this country primarily for jobs. Their ambulatory health care use is low compared with that of all Latinos and all persons nationally, and their rates of hospitalization are comparable except for hospitalization for childbirth. Almost half of married undocumented Latinos have a child who is a U.S. citizen. Excluding undocumented immigrants from receiving government-funded health care services is unlikely to reduce the level of immigration and likely to affect the well-being of children who are U.S. citizens living in immigrant households.

The influence of fatalism on self-reported use of Papanicolaou smears.

OBJECTIVE: Our objective was to examine the demographic and other predictors of fatalistic beliefs among Latinas (Hispanic women) and Anglo (non-Hispanic Caucasian) women and to assess the impact of these beliefs on the use of cervical cancer screening services. METHODS: We used ethnographic interviews and a cross-sectional telephone survey in Orange County, California. Our sample included 94 Latinas and 27 Anglo women selected through organization-based network sampling for the ethnographic interviews and 803 Latinas and 422 Anglo women randomly selected for the telephone survey. RESULTS: Latina immigrants (Latinas born outside the United States) were more likely than U.S.-born Latinas or Anglo women to have fatalistic beliefs. Immigration, education levels, and insurance status predicted fatalistic beliefs. Fatalistic beliefs were independent predictors of Pap smear use by Latinas but not Anglo women. For example, after adjusting for potentially confounding variables, Latinas who believed that fate was a risk factor for cervical cancer (odds ratio [OR] = .58), that they would rather not know if they had the disease (OR = .58), and that there is nothing one can do to prevent it (OR = .45) were less likely than others to report that they have had a Pap smear within the prior three years. Health insurance status, marital status, and immigration also predicted use of Pap smears. Insured Latinas were more likely than uninsured Latinas (OR = 2.89) to report having a Pap smear within the prior three years. In addition, married Latinas (OR = 2.32) and Anglo women (OR = 3.09) were more likely than unmarried women to report having appropriate cervical cancer screening. Finally, Latina immigrants were less likely than other Latinas to report having a Pap smear (OR = .26). CONCLUSIONS: We conclude that fatalistic beliefs are among the factors that negatively influence Latinas' use of Pap smears and that it is important for health care professionals to address those beliefs. Continued efforts are also necessary to decrease the economic and structural barriers to cervical cancer screening.
