Cancer screening in women: body mass index and adherence to physician recommendations

BACKGROUND: The reasons that obese women are less likely to obtain mammograms and Papanicolaou tests (Pap smears) are poorly understood. This study evaluated associations between body mass index (BMI) and receipt of and adherence to physician recommendations for mammography and Pap smear. METHODS: Data from the 2000 National Health Interview Survey (8289 women aged 40 to 74 years) were analyzed in 2006 using logistic regression. Women with previous hysterectomy were excluded from Pap smear analyses (n=5521). Outcome measures were being up-to-date with screening, receipt of physician recommendations, and women's adherence to physician recommendations for mammography and Pap smear. RESULTS: After adjusting for sociodemographic variables, healthcare access, health behaviors, and comorbidity, severely obese women (BMI > 40 kg/m(2)) were less likely to have had mammography within 2 years (odds ratio [OR]=0.50, 95% confidence interval [CI]=0.37-0.68) and a Pap smear within 3 years (OR=0.43, 95% CI=0.27-0.70). Obese women were as likely as normal-weight women to receive physician recommendations for mammography and Pap smear. Severely obese women were less likely to adhere to physician recommendations for mammography (OR=0.49, 95% CI=0.32-0.76). Women in all obese categories (BMI > 30 kg/m(2)) were less likely to adhere to physician recommendations for Pap smear (ORs ranged from 0.17 to 0.28, p<0.001). CONCLUSIONS: Obese women are less likely to adhere to physician recommendations for breast and cervical cancer screening. Interventions focusing solely on increasing physician recommendations for mammography and Pap smears will probably be insufficient for obese women. Additional strategies are needed to make cancer screening more acceptable for this high-risk group.     

Utilization of screening mammography as a preventive practice prior to initiating a population-based breast cancer screening program

Factors associated with the level of utilization of screening mammography as a preventive practice were analyzed prior to initiating a population-based breast cancer screening program. A questionnaire was used to collect information about screening mammography utilization during the last 4 years among women invited to enroll in the program. Sociodemographic and health factors, and health services utilization were studied. A screening mammography in the last 4 years had been performed on 59.3% of the 8867 women interviewed. The utilization of mammography was higher among women who were younger, had a higher education level, or had previous visits to a physician (P < 0.001). The variables more strongly associated with use of screening mammography were: visit to a gynecologist and performance of a pap smear. Also associated with the utilization of screening mammography were: personal history of breast pathology, family history of breast cancer, breast self-examination, and recent visit to a general practitioner. Self-perceived health presented an inverse relation with screening mammography use (P < 0.001). The use of screening mammography appears to have increased in recent years, although inequalities persist which the breast cancer screening programs help to modulate. Mammographic frequency only would be deemed appropriate by the European guidelines in fewer than one-half of the cases.     

Use of mammography and Pap smear in Estonia,a country without organized cancer screening

Summary Objectives: To analyze mammography and Pap smear status in Estonia where no organized population-based cancer screening is available. Methods: 5000 individuals (aged 16–64) were randomly chosen from the national population register; among them, 1755 women filled out postal questionnaires. Results: 50% of respondents aged 45–64 reported having taken a mammogram, 51% of women aged 25–64 had the Pap smear at least once in their lifetime. Corresponding figures for the past two years were 37% and 30%. Irrespective of age, women taking fewer tests over the past two years were rural workers, unemployed, and health behavior recommendations ignorers. In most cases, initiative for mammogram came from women, and from the physician in the case of Pap smear. Moderate increase in mammography use occurred after a project for early detection of breast cancer was launched. Conclusion: Women must continuously be informed that early detection of breast and cervical cancer is possible. Young women should be encouraged to ask for Pap testing. Knowledge of family physicians should be improved. Submitted: 13 February 2006; Revised: 4 October 2006; Accepted: 8 November 2006     

Cancer screening behaviors among U.S. women: breast cancer, 1987-1989, and cervical cancer, 1988-1989.

Data from the Behavioral Risk Factor Surveillance System (BRFSS) were used to examine trends in breast and cervical cancer screening behaviors among U.S. women in selected states. Data reported are from the 1987, 1988, and 1989 BRFSS for breast cancer screening (mammography) and from the 1988 and 1989 BRFSS for cervical cancer screening (Papanicolaou [Pap] smear). Results are presented as either state-specific or state-aggregate data for the years noted above. State-specific analyses indicated that self-reported mammography utilization increased between 1987 and 1989. Although whites and blacks reported similar mammography utilization rates both for screening and for a current or previous breast problem, disparities were evident among women of different ages and incomes. The proportion of women who reported ever having had a Pap smear and having heard of a Pap smear were extremely high and remained fairly consistent across the 2 survey years. State-aggregate analyses, however, showed that the percentage of women who had had a Pap smear within the previous year was negatively associated with age and positively associated with income. A higher proportion of blacks than whites obtained Pap smears. These results indicate that certain segments of the population are not taking full advantage of available breast and cervical cancer screening technologies. Public health strategies, such as those outlined in the Breast and Cervical Cancer Mortality Prevention Act of 1990 (Public Law 101-354), should enhance screening opportunities for these women.     

Race and mammography use in two North Carolina counties.

OBJECTIVES: This study investigated racial differences in mammography use and their association with physicians' recommendations and other factors. METHODS: The study used 1988 survey data for 948 women 50 years of age and older from the New Hanover Breast Cancer Screening Program. Racial differences in terms of physician recommendation, personal characteristics, health characteristics, and attitudes toward breast cancer and mammography were examined. Factors at least minimally associated with race and use were included in multivariate logistic regression analyses to examine the effect of race while controlling for other factors. RESULTS: In comparison with White women. Black women were half as likely to report ever having had a mammogram (27% vs 52%) and having a mammogram in the past year (17% vs 36%). Black women also significantly less often reported physician recommendation (25% vs 52%). Although Black and White women differed significantly in other characteristics, multivariate logistic regression analyses indicated that physician recommendation accounted for 60% to 75% of the initial racial differences in mammography use. CONCLUSIONS: Understanding physicians' recommendations for breast cancer screening is a critical first step to increasing mammography use in disadvantaged populations.     

Health Care Access and Breast Cancer Screening Among Latinas Along the California–Mexican Border

Latinas are more likely to exhibit late stage breast cancers at the time of diagnosis and have lower survival rates compared to white women. A contributing factor may be that Latinas have lower rates of mammography screening. This study was guided by the Behavioral Model of Health Services Use to examine factors associated with mammography screening utilization among middle-aged Latinas. An academic–community health center partnership collected data from community-based sample of 208 Latinas 40 years and older in the San Diego County who completed measures assessing psychosocial factors, health care access, and recent mammography screening. Results showed that 84.6 % had ever had a mammogram and 76.2 % of women had received a mammogram in the past 2 years. Characteristics associated with mammography screening adherence included a lower acculturation (OR 3.663) a recent physician visit in the past year (OR 6.304), and a greater confidence in filling out medical forms (OR 1.743), adjusting for covariates. Results demonstrate that an annual physical examination was the strongest predictor of recent breast cancer screening. Findings suggest that in this community, improving access to care among English-speaking Latinas and addressing health literacy issues are essential for promoting breast cancer screening utilization.     

The importance of physician encouragement in breast cancer screening of older women.

METHODS. The relationship between physician encouragement and breast cancer screening is examined with a population-based survey of 630 women between the ages of 45 and 75. Although the women interviewed were selected on the basis of their noncompliance with mammography guidelines, nearly half had previously had at least one mammogram. RESULTS. Women reported having received more physician encouragement of breast self-examination than of mammography. Older women reported less encouragement of both screening modalities than younger women. Multivariate analyses revealed physician encouragement to be more strongly associated with screening mammography than with health status, health care utilization, attitudes, and sociodemographic characteristics: those who reported having received physician encouragement were nearly four times more likely to have ever had screening mammography. CONCLUSIONS. These and related findings are used to highlight the critical importance of physician behavior in the secondary prevention of breast cancer in older women and to identify types of patients whose needs for screening are most likely to be overlooked by physicians.     

Knowledge, Attitudes, and Patterns of Cancer Screening: A Self-report Among Foreign Born Hispanic Women Utilizing Rural Migrant Health Clinics

Hispanics are the fastest growing minority in the United States and are currently Washington state's largest minority, with the highest growth rates found in the rural agricultural areas of eastern Washington state. Because breast and cervical cancer mortality rates are higher in Hispanics than other U.S. women, subgroups of Hispanic women with the lowest cancer screening utilization rates need to be identified and targeted for cancer control intervention to most effectively reduce late-stage cancer diagnoses and mortality. A study was conducted at six migrant health clinics located throughout eastern Washington state to discern age-specific proportions for utilization of mammography, breast self-examination, and Pap smears among Hispanic migrants to the United States. Knowledge and attitudes regarding these procedures also were assessed and face-to-face interviews were completed with 512 women. Among women 20 years or older, 15 percent had never heard of a Pap smear, only 78 percent had ever received a Pap smear, and only 44 percent had received a Pap smear within the prior year. In all, 73 percent of the women had been taught breast self-examination, 62 percent performed breast self-examination, and 41 percent had performed a breast self-examination in the prior month. Among women 40 years or older, only 38 percent had never heard of a mammogram, 38 percent had ever received a mammogram, and only 30 percent had received a mammogram in the prior two years. Cost was reported as a major barrier for screening in this population. Additionally, a substantial proportion of the women perceived Pap smears and mammography as unnecessary or diagnostic procedures, rather than preventive health measures.     

Breast cancer screening attitudes and behaviors of rural and urban women.

This study was carried out to assess the breast cancer knowledge, attitudes, and awareness of women age 40 to 74 in Alberta, a Canadian province of 2.4 million people. This analysis compares the attributes of 538 rural women, defined as those living between 1 and 3 hr drive from the major cities in Alberta, and 735 urban women who lived in one of these two cities. Rural women were found to have the same basic knowledge of breast cancer or perceptions of barriers to mammography, but had more negative attitudes about breast cancer itself. Despite their similar access to physician care, they were less likely to have had a recent clinical breast examination or mammogram (P less than 0.001). These differences remained when adjustment was made for demographic background variables; the adjusted prevalence rate ratio for a screening mammogram in the past 2 years was 0.52 (95% C.I., 0.43, 0.64), and for intention to have a mammogram in the next 2 years, 0.75 (0.63, 0.90). The results suggest particular program delivery strategies when planning for provision of breast screening information and service to the large subgroup of rural women.     

Questionnaire survey of women aged 56-59 years: consultations in general practice, use of hormone replacement therapy (HRT) and participation in screening programmes

OBJECTIVES: To ascertain attitudes to consultations in general practice and the gender of the doctor. To determine whether women participate in the National Health Service (NHS) screening programmes available to them and their use of hormone replacement therapy (HRT). DESIGN: Postal questionnaire survey to women aged 56-59 years. SETTING: The Honiton Group Practice, East Devon, UK. PARTICIPANTS: Two hundred and ninety-four of the 334 eligible women returned the questionnaire (response rate 88%). MAIN OUTCOME MEASURES: Women's embarrassment on consulting general practitioners (GPs) and preference for a female doctor. Up-to-date cervical smears and mammography screening in eligible women and use of HRT. RESULTS: A large majority of women (248/294; 84.4%) were not embarrassed when consulting a GP and did not express a preference to see a woman GP for any problem (240/294; 81.6%). However 123/294 (41.8%) did express a preference to see a woman doctor for 'women's problems'. Sixty-five women had had a hysterectomy, and 218 of the remaining 229 (95.2%) had had a smear in the past 5 years. For breast screening, 267/294 (90.8%) had undergone mammography in the previous 3 years. Ninety-three women (32%) were currently on HRT, and on record searching a total of 146 (49.7%) had at some time been HRT users. CONCLUSIONS: Embarrassment does not appear to be a major problem for consultations related to female health. A well-organised general practice with motivated patients can achieve very high uptakes of both cervical and breast screening programmes. Interest in HRT has also risen, with half the women aged 56-59 years having used systemic HRT.     

The influence of previous breast cancer upon mammography utilization.

Women with a previous history of breast cancer are at increased risk for developing cancer in the opposite breast. However, the literature is inconsistent regarding whether a previous history of breast cancer is associated positively with mammography utilization. Some studies indicate that women with a previous history of breast cancer are less likely to utilize mammography, although behavioral models of health care theorize that women with a history of breast cancer may be more vigilant regarding the disease. We analyzed responses from 830 women > or =50 years who participated in the 1998 National Health Interview Survey. A significantly greater proportion of women with breast cancer reported had a mammogram in the previous year (73.13%) as compared with women who did not have breast cancer (56.69%). Although a previous history of breast cancer was found to be associated positively with mammography use, women with public sources of health insurance are less likely to report mammography use. Results indicate that women with a previous history of breast cancer appear aware of the necessity for continued screening. However, enabling factors such as type of health insurance continue to exert an influence upon the utilization of mammography.     

Peer Reviewed: Nonadherence to Breast and Cervical Cancer Screening: What Are the Linkages to Chronic Disease Risk?

Background

Several preventive practices that reduce chronic disease risk have been associated with breast and cervical cancer screening, including maintenance of normal weight and avoidance of cigarette smoking. A history of certain chronic illnesses such as diabetes and cardiovascular disease has also been related to cancer screening. Nevertheless, studies that have attempted to identify women who are less likely to have had a recent breast or cervical cancer screening test have infrequently examined the associations of breast and cervical cancer screening with multiple health factors that influence chronic disease risk.

Methods

To clarify relationships between cancer screening and health behaviors and other factors that influence chronic disease risk, we examined the self-reported breast and cervical cancer screening practices of women in the United States by using data from the 1999 Behavioral Risk Factor Surveillance System. The women were described according to their recent use of mammography and the Papanicolaou test, physician visits within the past year, health insurance coverage, and preventive practices that reduce chronic disease risk.

Results

Overall, 74.5% (95% CI, 73.9%-75.1%) of the women in this sample aged 40 years or older (n = 56,528) had received a mammogram within the past 2 years. The percentage of women who had been screened for breast cancer, however, varied widely by factors associated with reducing the risk of chronic disease (e.g., cholesterol check in the past 2 years, blood pressure check in the past 2 years, normal weight, avoidance of cigarette smoking) and having access to health care (e.g., health insurance coverage, recent physician visit). Similarly, 84.4% (95% CI, 83.9%-84.9%) of all women aged 18 years or older who had not undergone a hysterectomy (n = 69,113) had received a Papanicolaou test in the past 3 years, and factors associated with reduced chronic disease risk and health care access were related to having had a recent Papanicolaou test.

Conclusion

The results of this study suggest that underscreened women who are at risk for breast and cervical cancer are likely to benefit from programs that identify and address coexisting prevention needs. The identification of coexisting prevention needs might assist in developing interventions that address multiple risks for chronic disease among women and might subsequently help improve the efficiency and effectiveness of prevention programs.     

The Group-Based Medical Mistrust Scale: psychometric properties and association with breast cancer screening

BACKGROUND: There is little research on medical mistrust as a barrier to breast cancer screening. This study investigated the psychometric properties of a new scale, the Group-Based Medical Mistrust Scale (GBMMS), and its association with cancer screening attitudes and breast cancer screening practices among African American and Latina women. METHODS: Participants were 168 African American and Latina urban women who completed the GBMMS and measures of sociodemographics, cancer screening pros and cons, acculturation, breast cancer screening practices and physician recommendation of such screening. RESULTS: A principal components analysis of GBMMS items revealed three factors that were analyzed as subscales: (1) suspicion, (2) group disparities in health care, and (3) lack of support from health care providers. Convergent validity of the GBMMS was supported by its negative association with perceived benefits of cancer screening and acculturation and positive association with perceived disadvantages of cancer screening. Results further showed that women who reported no previous mammogram or a long-term lapse in mammography participation (>5 years) had significantly higher total GBMMS scores (P < 0.04) compared to women who were either adherent to mammography guidelines or nonadherent but reported a mammogram within the past 5 years. This analysis controlled for physician recommendation. CONCLUSIONS: Results support the validity of the GBMMS and its association with breast cancer screening adherence. The GBMMS may be used to further investigate medical mistrust as a barrier to screening for cancers for which ethnic group disparities have been observed.     

Initial and Repeat Mammography Screening: Different Behaviors/Different Predictors

Despite evidence of the efficacy of mammography in early detection of breast cancer, many women choose not to have a mammogram. Some women who have an initial mammogram do not return for a second one. Many others, especially minority women, and those who live in rural areas or in a low socioeconomic class, are not being screened according to recommended guidelines. The full benefits of early detection are available only if women receive regular screening. This study of 830 randomly selected women over age 50 from rural, eastern North Carolina included women who had never had a mammogram (213), women who had had a mammogram but not in the prior 2 years (89), and women who reported having had a mammogram in the previous 2 years (528). Logistic regression was used to identify significant mammography predictor variables. The results support the robust role that provider recommendation plays in encouraging mammography behavior; they also demonstrate that past behavior is also a strong predictor of future screening participation. Only 13% of the women who had never had a mammogram reported obtaining a referral from their provider compared with 79% of the women who had a mammogram in the previous 2 years. Likewise, 75% of the women who had engaged in mammography behavior in the prior 2 years expressed a positive intention to be screened in the next year compared with only 14% of those women who had never had a mammogram. Initial and repeat mammography screenings are different behaviors and are influenced by different factors. For provider counseling to be effective, the strategies employed need to consider past behavior as well as current recommendations, and they must incorporate a discussion of beliefs as well as reinforcement of regular screening behavior.     

Hispanic acculturation and utilization of cervical cancer screening in the US

BACKGROUND: Hispanic women have an incidence rate of invasive cervical cancer that is twice as high as that of non-Hispanic White women. Previous investigations have reported that Hispanics are less likely to utilize cancer screening services. Using data from the 2000 National Health Interview Survey, this study examined whether acculturation of Hispanic women was associated with cervical cancer screening. METHODS: The subjects included 2307 Hispanic women aged 21-70 who did not have a history of cervical cancer or a hysterectomy. Women were analyzed by acculturation level according to whether or not they ever had a Pap smear and had one in the previous year and previous 3 years. RESULTS: Acculturation levels tended to be inversely correlated with no Pap smear. Compared to lower acculturated women, women who were more acculturated were less likely to never had a Pap smear (OR = 0.86; 95% CI = 0.58-1.27 for moderate acculturated women and OR = 0.51; 95% CI = 0.29-0.89 for higher acculturated women). Similar results were found for having no Pap smear within the past 3 years (OR = 0.83; 95% CI = 0.61-1.13 for moderate acculturated women and OR = 0.73; 95% CI = 0.49-1.08 for higher acculturated women). CONCLUSION: The findings show that lower acculturation was associated with the under use of cervical cancer screening and suggest that these women might have barriers in accessing and utilizing Pap smears.     

Relationship between Pap smear performance and physician ordering a mammogram.

BACKGROUND. Although Pap smear screening for cervical cancer in general has been successfully implemented, mammography screening for breast cancer remains relatively underused. Patients having one screening test are more likely to have other screening tests performed. The objective of this study was to determine whether visits by women for Pap smears serve as opportunities for physicians to order a screening mammogram. METHODS. A matched case-control design was used for this retrospective study. Eligible women included those over 50 years of age who had no history of breast cancer or mastectomy and who had made at least one visit to a family practice residency program during the 2-year study period. Cases were randomly selected from women who had mammograms performed. For each case, one control subject who did not have a mammogram was matched by age and number of visits. A chart audit was performed to collect data on the characteristics of these women and whether they completed their screening tests. RESULTS. The adjusted odds ratio (controlling for the patient's age and number of physician visits) for mammogram completion among women who had a Pap smear compared with those who did not was 6.67. This effect persisted after controlling for other confounding factors using logistic regression. CONCLUSIONS. Performing a Pap smear appears to serve as a prompt for the physician to order a screening mammogram. That physicians appear to provide screening tests, particularly Pap smears and mammograms, as a package of services should be considered when future efforts to improve implementation are made.     

Misconceptions about efficacy of mammography screening: a public health dilemma

OBJECTIVE: This study assessed accuracy of women's opinions about reduction in mortality from breast cancer attributable to mammography screening. DESIGN: Cross sectional survey. SETTING: General population of Geneva, Switzerland. PARTICIPANTS: 895 randomly selected women aged 40 to 80 years, free of breast cancer. RESULTS: Women estimated the proportion of deaths from breast cancer that regular mammography screening prevents in women over age 50. Only 19.3% of the respondents assessed screening efficacy realistically (that is, reduction by about one fourth); 52.0% overestimated efficacy; 26.0% "didn't know", and 2.6% stated that screening prevents no death. Women who believed mammography screening to be effective had more positive attitudes toward screening (higher scores of pros and lower scores of cons) and were more likely to plan to have a mammogram (both p<0.001). Lack of opinion about the benefit of mammography screening was more common among women who had not consulted a gynaecologist recently (p=0.02) nor had had a mammogram during the past two years (p=0.009), who had no opinion about their risk of breast cancer (p<0.001), and who were 70 to 80 years old (p=0.04). Compared with women who provided realistic estimates of screening efficacy, those who overestimated efficacy believed to be at higher risk of breast cancer than other women (p=0.04) and were more likely to be Swiss nationals (p=0.001). CONCLUSIONS: Most women overestimated and many were uninformed about the efficacy of mammography screening. Therefore, few women were able to take truly informed decisions about screening mammography.     

Factors associated with cervical cancer screening behavior among Vietnamese women

The purpose of this study was to gather information on the prevalence of pap smear testing among Vietnamese women and to identify predictive factors that influence women to engage in early cervical cancer detection behavior. One hundred and forty-one (141) Vietnamese women ages 18 years and older and living in Western Massachusetts were surveyed by telephone. The overall socioeconomic status of these women was low. Survey results showed that among these women, the use of pap tests was lower than for the U.S. female population in general. Approximately one-half of the respondents reported having had a pap smear. Bivariate and multivariate methods, including logistic regression, were used to analyze the differences between users and nonusers. Bivariate analysis revealed that age, marital status, number of children, religion, regular physician care, and income were significantly related to a prior pap smear experience. The multivariate model for pap test included: age, income, length of residence in the U.S., and marital status. Compared to women who had never had a pap test, women who had were older, married, had higher incomes, and lived in the U.S. longer. It was concluded that this model is useful for screening cancer behavior in Vietnamese women 18 years and older and living in Western Massachusetts, but, in general, should not be used as a cancer screening tool in other populations, at least until similar assessments have been done for these populations.     

Beliefs and behaviors about Pap and breast self-examination among Thai immigrant women in Brisbane, Australia.

Regular screening is an important preventive method in reducing morbidity and mortality from cervical and breast cancer. In 1998, a cross-sectional study was conducted in Brisbane, Australia, among 145 Thai immigrant women, to explore cultural and social factors related to their use of Pap smear tests and breast self-examination (BSE). The study aimed at describing women's beliefs and perceptions about the body, breast and cervical cancer, and their perceptions of the causes of the diseases. It explored the women's perception of the severity and the effects of both cancers on aspects of patients' lives, and their chance of developing both cancers. The Thai immigrant women explained the causes of breast and cervical cancer using both traditional beliefs and medical knowledge. They perceived that both cancers affect a patient's health and her daily activities. Some women believed that they would develop cervical cancer if their perineum or vulva was "dirty." Some believed that they would have breast cancer because they had a history of benign tumor or cyst of a breast. Forty-four percent of the women had biennial Pap smears in the past five years and only 25% conducted BSE monthly in the past two years. Information relating to perceived barriers to undertake regular cervical cancer and breast cancer screenings and other health beliefs can be applied by health care personnel to increase Thai immigrant women's preventive health behaviors.     

Hispanic women's breast and cervical cancer knowledge, attitudes, and screening behaviors

PURPOSE: This study examined breast and cervical cancer knowledge, attitudes, and screening behaviors among different Hispanic populations in the United States. DESIGN: Data were collected from a random digit dial telephone survey of 8903 Hispanic adults from eight U.S. sites. Across sites, the average response rate was 83%. SETTING: Data were collected as part of the baseline assessment in a national Hispanic cancer control and prevention intervention study. SUBJECTS: Analysis was restricted to 2239 Hispanic women age 40 and older who were self-identified as either Central American (n = 174), Cuban (n = 279), Mexican American (n = 1550), or Puerto Rican (n = 236). MEASURES: A bilingual survey instrument was used to solicit information on age, education, income, health insurance coverage, language use, U.S.-born status, knowledge of screening guidelines, attitudes toward cancer, and screening participation. Differences in knowledge and attitudes across Hispanic groups were assessed by either chi-square tests or analysis of variance. Logistic regression models assessed the influence of knowledge and attitudes on screening participation. RESULTS: The level of knowledge of guidelines ranged from 58.3% (Mexican Americans) to 71.8% (Cubans) for mammography, and from 41.1% (Puerto Ricans) to 55.6% (Cubans) for Pap smear among the different Hispanic populations. Attitudes also varied, with Mexican Americans and Puerto Ricans having more negative or fatalistic views of cancer than Cuban or Central Americans. Knowledge was significantly related to age, education, income, language preference, and recent screening history. Overall, attitudes were not predictive of mammography and Pap smear behavior. CONCLUSIONS: Factors related to mammography and Pap smear screening vary among the different Hispanic populations. Limitations include the cross-sectional nature of the study, self-reported measures of screening, and the limited assessment of attitudes. The data and diversity of Hispanic groups reinforce the position that ethno-regional characteristics should be clarified and addressed in cancer screening promotion efforts. The practical relationships among knowledge, attitudes, and cancer screening are not altogether clear and require further research.
