Breast cancer screening behaviors and attitudes in three racial/ethnic groups

Young Black Women May be More Likely to Have First Mammogram Cancers: A New Perspective in Breast Cancer Disparities

INTRODUCTION

Black women are diagnosed with breast cancer at earlier ages and are 42% more likely to die from the disease than White women. Recommendations for commencement of screening mammography remain discordant. This study sought to determine the frequency of first mammogram cancers among Black women versus other self-reported racial groups.

METHODS

In this retrospective cohort study, clinical and mammographic data were obtained from 738 women aged 40-45 years who underwent treatment for breast cancer between 2010 and 2019 within a single hospital system. First mammogram cancers were defined as those with tissue diagnoses within 3 months of baseline mammogram. Multivariate logistic regression was applied to assess variables associated with first mammogram cancer detection.

RESULTS

Black women were significantly more likely to have first mammogram cancer diagnoses (39/82, 47.6%) compared with White women (162/610, 26.6%) and other groups (16/46, 34.8%) [p < 0.001]. Black women were also more likely to have a body mass index > 30 (p < 0.001), higher clinical T categories (p = 0.02), and present with more advanced clinical stages (p = 0.03). Every month delay in mammographic screening beyond age 40 years (odds ratio [OR] 1.06, 95% confidence interval [CI] 1.05-1.07; p < 0.0001), Black race (OR 2.24, 95% CI 1.10-4.53; p = 0.03), and lack of private insurance (OR 2.41, 95% CI 1.22-4.73; p = 0.01) were associated with an increased likelihood of cancer detection on first mammogram.

CONCLUSION

Our findings suggests that Black women aged 40-45 years may be more likely to have cancer detected on their first mammogram and would benefit from starting screening mammography no later than age 40 years, and for those with elevated lifetime risk, even sooner.

Racial and socioeconomic disparities in lung cancer screening in the United States: A systematic review

Nonsmall cell lung cancer (NSCLC) is the leading cause of cancer deaths. Lung cancer screening (LCS) reduces NSCLC mortality; however, a lack of diversity in LCS studies may limit the generalizability of the results to marginalized groups who face higher risk for and worse outcomes from NSCLC. Identifying sources of inequity in the LCS pipeline is essential to reduce disparities in NSCLC outcomes. The authors searched 3 major databases for studies published from January 1, 2010 to February 27, 2020 that met the following criteria: 1) included screenees between ages 45 and 80 years who were current or former smokers, 2) written in English, 3) conducted in the United States, and 4) discussed socioeconomic and race-based LCS outcomes. Eligible studies were assessed for risk of bias. Of 3721 studies screened, 21 were eligible. Eligible studies were evaluated, and their findings were categorized into 3 themes related to LCS disparities faced by Black and socioeconomically disadvantaged individuals: 1) eligibility; 2) utilization, perception, and utility; and 3) postscreening behavior and care. Disparities in LCS exist along racial and socioeconomic lines. There are several steps along the LCS pipeline in which Black and socioeconomically disadvantaged individuals miss the potential benefits of LCS, resulting in increased mortality. This study identified potential sources of inequity that require further investigation. The authors recommend the implementation of prospective trials that evaluate eligibility criteria for underserved groups and the creation of interventions focused on improving utilization and follow-up care to decrease LCS disparities.

Who does not get screened? A simple model of the complex relationships in mammogram non-attendance

With increasing mammogram rates, identifying attributes of non-attending women entails going beyond differences in demographic groups to reveal complex interactions among personality attributes. In this study, we analyzed survey data from 474 women aged 41 years and older using decision trees. By incorporating personality, religiousness, and age, we were able to correctly classify 42.9 percent of non-attenders compared to 4.4 percent with logistic regression analysis. Our findings suggest that incorporating personality and religiousness attributes may increase non-attender identification. Furthermore, the simple profile generated by decision trees provides a clear map useful for intervention planning.

Disparities in breast cancer treatment and outcomes: biological, social, and health system determinants and opportunities for research

Racial disparities in breast cancer mortality have been widely documented for several decades and persist despite advances in receipt of mammography across racial groups. This persistence leads to questions about the roles of biological, social, and health system determinants of poor outcomes. Cancer outcomes are a function not only of innate biological factors but also of modifiable characteristics of individual behavior and decision making as well as characteristics of patient-health system interaction and the health system itself. Attempts to explain persistent racial disparities have mostly been limited to discussion of differences in insurance coverage, socioeconomic status, tumor stage at diagnosis, comorbidity, and molecular subtype of the tumor. This article summarizes existing literature exploring reasons for racial disparities in breast cancer mortality, with an emphasis on treatment disparities and opportunities for future research. Because breast cancer care requires a high degree of multidisciplinary team collaboration, ensuring that guideline recommended treatment (such as endocrine therapy for hormone receptor positive patients) is received by all racial/ethnic groups is critical and requires coordination across multiple providers and health care settings. Recognition that variation in cancer care quality may be correlated with race (and socioeconomic and health system factors) may assist policy makers in identifying strategies to more equally distribute clinical expertise and health infrastructure across multiple user populations.

Predictors of screening mammography among Asian Indian American women: a cross-sectional study in the Baltimore-Washington metropolitan area

OBJECTIVE

To assess adherence to screening mammography guidelines and examine predictors of having a mammogram in the past 2 years among immigrant Asian Indian women (AIW) aged > or = 40 years.

METHODS

Face-to-face surveys of 418 AIW in the Baltimore-Washington metropolitan area were conducted. Subjects were recruited through Asian Indian (AI) religious and other community-based organizations.

RESULTS

Of the 418 AIW surveyed, 83% had ever had a mammogram, and 70% had obtained a mammogram within the past 2 years. AIW who had lived in the United States for > 10 years had a higher rate of obtaining a mammogram (75.4%) within the past 2 years than did those who had lived in the United States for < or = 10 years (24.6%). In multiple logistic regression analysis, length of stay in the United States, marital status, knowledge of mammogram guidelines, age, having health insurance, physician recommendations, and number of relatives who had a mammogram were positively associated with having a mammogram within the past 2 years. Physician ethnicity and not having a healthcare provider were negatively associated with having a mammogram within the past 2 years.

CONCLUSIONS

This study lays a foundation for designing guidelines for interventions to improve mammography screening behaviors among AIW women. Increasing the use of mammogram to the levels recommended by guidelines will require a two-pronged approach directed at both AIW and AI physicians.

Beliefs and attitudes about lung cancer screening among smokers

The National Lung Screening Trial (NLST) recently reported that annual computed tomography (CT) screening is associated with decreased lung cancer mortality in high-risk smokers. Beliefs about lung cancer and screening, particularly across race and ethnicity, and their influence on CT screening utilization are largely unexamined. Our study recruited asymptomatic, high-risk smokers, 55-74 years of age from primary care clinics in an academic urban hospital. Guided by the self-regulation theory, we evaluated cognitive and affective beliefs about lung cancer. Intention to screen for lung cancer with a CT scan was assessed by self-report. We used univariate and logistic regression analyses to compare beliefs about screening and intention to screen among minority (Blacks and Hispanics) and non-minority participants. Overall, we enrolled 108 participants, of which 40% were Black and 34% were Hispanic; the mean age was 62.3 years, and median pack-years of smoking was 26. We found that intention to screen was similar among minorities and non-minorities (p=0.19); however, Hispanics were less likely to report intention to screen if they had to pay for the test (p=0.02). Fatalistic beliefs, fear of radiation exposure, and anxiety related to CT scans were significantly associated with decreased intention to screen (p<0.05). Several differences were observed in minority versus non-minority participants' beliefs toward lung cancer and screening. In conclusion, we found that concerns about cost, which were particularly prominent among Hispanics, as well as fatalism and radiation exposure fears may constitute barriers to lung cancer screening. Lung cancer screening programs should address these factors to ensure broad participation, particularly among minorities.

Consistency in attitudes across cancer screenings in medically underserved minority populations

While a wide range of behavioral and psychosocial literature explores attitudes and beliefs towards cancer screenings, fewer studies examine attitudes across cancer screening types. We draw on quantitative and qualitative findings from a 4-year prospective study based at a community health center serving diverse, low-income patients. Methods included self-report surveys (n = 297), medical chart abstraction, and several qualitative methods with a subsample of participants. Participants included white, African-American, Vietnamese, and Latino patients who were diagnosed with diabetes, hypertension, or both. Patients' attitudes (both positive and negative) towards cancer screening types were remarkably consistent across cancer screening types. These effects were stronger among men than women. Never having had a cancer screening was generally associated with more unfavorable attitudes towards all screenings. Qualitative interviews indicate the importance of information circulated through social networks in shaping attitudes towards cancer screenings.

CONDENSED ABSTRACT

In a multi-method study of attitudes towards cancer screening among medically underserved patients in a primary care setting, we found that attitudes (both positive and negative) were remarkably consistent across cancer screening types.

An assessment of American Indian women's mammography experiences

BACKGROUND

Mortality from breast cancer has increased among American Indian/Alaskan Native (AI/AN) women. Despite this alarming reality, AI/AN women have some of the lowest breast cancer screening rates. Only 37% of eligible AI/AN women report a mammogram within the last year and 52% report a mammogram within the last two years compared to 57% and 72% for White women. The experiences and satisfaction surrounding mammography for AI/AN women likely are different from that of women of other racial/ethnic groups, due to cultural differences and limited access to Indian Health Service sponsored mammography units. The overall goals of this study are to identify and understand the mammography experiences and experiential elements that relate to satisfaction or dissatisfaction with mammography services in an AI/AN population and to develop a culturally-tailored AI/AN mammography satisfaction survey.

METHODS AND DESIGN

The three project aims that will be used to guide this work are: 1) To compare the mammography experiences and satisfaction with mammography services of Native American/Alaska Native women with that of Non-Hispanic White, Hispanic, and Black women, 2) To develop and validate the psychometric properties of an American Indian Mammography Survey, and 3) To assess variation among AI/AN women's assessments of their mammography experiences and mammography service satisfaction. Evaluations of racial/ethnic differences in mammography patient satisfaction have received little study, particularly among AI/AN women. As such, qualitative study is uniquely suited for an initial examination of their experiences because it will allow for a rich and in-depth identification and exploration of satisfaction elements.

DISCUSSION

This formative research is an essential step in the development of a validated and culturally tailored AI/AN mammography satisfaction assessment. Results from this project will provide a springboard from which a maximally effective breast cancer screening program to benefit AI/AN population will be developed and tested in an effort to alter the current breast cancer-related morbidity and mortality trajectory among AI/AN women.

A two-center study of Muslim women's views of breast cancer and breast health practices in Pakistan and the UK

Breast health awareness practices of Pakistani Muslim women in the UK and Pakistan is unknown. Focus group interviews were used to investigate the impact of culture and psychosocial issues on breast health awareness involving 44 women in Lahore and London. Women based in Lahore were more inquisitive about breast cancer and held more developed views compared with British Pakistani Muslim women. Women concurred that concise and relevant breast health education is needed irrespective of faith to improve cultural sensitivity and awareness in both Pakistani communities (both men and women).

Effect of a multimodal reminder program on repeat mammogram screening

BACKGROUND

Patient mammogram reminders are effective but have not been fully implemented in practice to improve routine screening. The effectiveness of implementation and maintenance phases of a multimodal reminder program that incorporated automated calls capable of efficiently reaching large numbers of women was evaluated to improve repeat mammography screening.

DESIGN

A quasi-experimental study was conducted in 2008 using electronic medical record data during three time periods: pre-reminder phase (2004), post-reminder implementation phase (2006), and post-reminder maintenance phase (January 1-July 1, 2007).

SETTING/PARTICIPANTS

Participants were female Kaiser Permanente Northwest HMO members aged 42 years or more who were 20 months past their last mammogram (index date) (N=35,104). The intervention program targeted women aged 50-69 years. Women aged 42-49 years (for whom clinical guidelines also recommend mammography) not targeted by the program constituted the primary comparison group (CG1).

INTERVENTION

A "mammogram due soon" postcard was mailed to participants 20 months after their last mammogram, followed by up to two automated phone calls and one live call for nonresponders.

MAIN OUTCOME MEASURES

The outcome measure was the time until participants received a mammogram in the 10 months following the index date.

RESULTS

Pre-reminder, 63.4% of targeted women completed a mammogram; this number increased to 75.4% in the post-reminder implementation phase; 80.6% completed a mammogram in the maintenance phases. After controlling for demographics and clinic visits, intervention women were 1.51 times more likely to complete a mammogram (CI=1.40, 1.62) post-reminder implementation, compared to CG1. The effect was maintained in 2007 (hazard ratio 1.81, CI=1.65, 1.99).

CONCLUSIONS

The study found that this multimodal reminder system could be effectively implemented and maintained in a large health system. If widely implemented, this intervention could substantially improve community mammography screening.

African-American and low-socioeconomic status patients have a worse prognosis for invasive ductal and lobular breast carcinoma: do screening criteria need to change?

BACKGROUND

Determine the effect of race, socioeconomic status (SES) and other demographic variables on outcomes of patients with invasive ductal and lobular breast cancer.

STUDY DESIGN

Florida cancer registry and inpatient hospital data were queried for patients diagnosed with invasive breast cancer from 1998 to 2002.

RESULTS

A total of 63,472 patients with breast cancer were identified. Overall, 90.5% of patients were Caucasian, 7.6% African American, and 8.7% Hispanic. African-American patients presented at a younger age and with more-advanced disease, 10.5% presented with breast cancer before the age of 40 years, and 22.4% before 45 years of age. African-American patients were less likely to undergo operations. Similarly, low-SES patients were less likely to have operations and presented more often with larger tumors. Stepwise multivariate analysis revealed a substantial drop in the hazard ratio for African-American patients once correction for stage of presentation was made, suggesting that disparities in breast cancer outcomes are, in part, a result of advanced stage at presentation. Race and low SES were independent predictors of worse prognosis when controlling for patient comorbidities and treatment.

CONCLUSIONS

Dramatic disparities by patient race and SES exist in breast cancer. Our study integrates previous smaller studies, providing comprehensive insight into African-American patients and their outcomes for breast cancer. Earlier screening programs and greater access to cancer care for the poor and African Americans are needed. Successful institution of such programs will not completely erase disparities in outcomes for breast cancer in African-American patients.

Social workers as patient navigators for breast cancer survivors: what do African-American medically underserved women think of this idea?

Patient navigation (PN) is a new initiative in health care aimed at reducing disparities by assisting patients in overcoming barriers within the health care system. As PN programs grow around the country, it is important to consult the key stakeholders in the development of these programs. The purpose of this qualitative study was to discuss the needs of medically underserved cancer patients and allow them the opportunity to provide input on models of care to meet their needs. Four focus groups were conducted in three major cities across Tennessee. Research participants (n = 36) were recruited by the staff in area cancer support programs and treatment programs across the state and through recruitment flyers at various treatment centers and community organizations. Findings revealed four key themes in the development of PN programs: (1) the PN needs to address access to quality care issues; (2) the PN needs to address the emotional and practical concerns of the cancer survivor, (3) the PN needs to address family concerns; (4) the PN needs to be involved across the continuum of care from time of diagnosis into long-term survivorship. Oncology social workers have a unique opportunity to meet the needs of medically underserved cancer patients through the PN movement. Our profession is a key stakeholder in this movement. We need to advocate for trained oncology social workers to actively pursue the role of patient navigators to ensure that the needs of medically underserved cancer survivors and their families are met.

Ethnic experience of cancer: a qualitative study of Chinese-Australians in Brisbane, Queensland

This article reports on the findings of a recent study of cancer experiences of members in the Chinese community in Brisbane, the state capital of Queensland. Results of the study have shown that the belief in fate and luck, as well as stoicism about cancer, is very common among cancer patients and their family members. Their general strategy for coping with cancer is often passive. Families play the most important role in determining the strategy for helping the cancer patients in coping with the illness. Most prefer to keep the illness secret and private within the family. Implications of the findings from this study will be discussed for the development of culturally appropriate programs for cancer prevention and treatment for the Chinese community.

Are Patterns of Health Behavior Associated with Cancer Screening?

Purpose.

This study investigates the relationship between patterns of health behaviors and the use of cancer-screening tests while controlling for sociodemographic and health system factors.

Design.

Cross-sectional analysis of the 2000 National Health Interview (NHIS).

Setting.

Nationally representative sample.

Subjects.

Adults 50 years and older.

Measures.

Use of cancer-screening tests, health behaviors, sociodemographic factors, and health system factors from self-reported responses from the NHIS. Sixteen health behavior patterns were identified based on lifestyle recommendations for physical activity, tobacco use, alcohol consumption, and fruit and vegetable consumption.

Results.

Health behavior patterns, age, educational attainment, usual source of care, and health insurance were significantly associated with the use of breast, cervical, and colorectal cancer screening (p < .05). Approximate B2 for the four models ranged from .067 for colorectal cancer screening in women to .122 for cervical cancer screening. Having a usual source of care was the strongest correlate of screening; the magnitude of associations for health behavior patterns and demographic variables and screening was similar and much smaller than those for usual source of care.

Conclusion.

These findings demonstrate relationships between patterns of multiple health behaviors and use of recommended cancer-screening tests, even when accounting for factors known to influence test use. This suggests potential for addressing cancer screening in the context of multiple behavior change interventions once barriers to health care access are removed.

Which women aren’t getting mammograms and why? (United States)

OBJECTIVE

This study investigates why women who reported no recent mammogram did not get the test.

METHODS

Using data from the 2000 National Health Interview Survey (NHIS), we examine correlates of mammography use among women 40 years and older (n = 10,212), with particular focus on the 30% (n = 3,188) who reported no recent mammogram. Non-screening is examined in the context of two important correlates of mammography use-access to health care and a physician's recommendation to get a mammogram.

RESULTS

In total, 80% of non-screeners who reported having access to healthcare did not receive a recommendation for a mammogram. Women age 65 years and older were more likely than younger women to report not receiving a recommendation (OR 1.77, 95% CI 1.25-2.50). For women who reported having access, non-screening was significantly more likely among younger women (40-49), those with less education, incomes less than 20,000 dollars, residence outside Metropolitan Statistical Areas (MSAs) and no family history of breast cancer. Among women with access problems, those who had not visited a primary care provider in the past year were much more likely to be non-screeners (80%) compared with those who had seen a provider (46%). Among women with access, those who reported put it off as the main reason for non-screening were significantly more likely to be younger and to be born in the U.S. than women who said that they didn't know they needed a mammogram.

CONCLUSIONS

Most non-screeners report not receiving a physician recommendation for mammography. Although a minority reported access problems, the effect of lacking access on utilization was strong and is accentuated when women without access do not see a doctor. These findings confirm the importance of a mammography recommendation and raise questions concerning whether this information is being conveyed by physicians or heard by patients.

Factors associated with the incompliance with mammogram screening among individuals with a family history of breast cancer or ovarian cancer

OBJECTIVE

The national guidelines recommend more intensive screening for breast cancer for women with a family history of breast or ovarian cancer. Using the data from the 2000 National Health Interview Survey (NHIS), we examined factors related to the underuse of mammogram in this population.

METHOD

The study subjects were 1,215 women aged 30-79 who had a family history of breast or ovarian cancer in their first-degree relatives. According to the American Cancer Society's guidelines for breast cancer screening, having no mammogram in last year was used as an outcome for this study. Socio-demographic characteristics, health-related conditions, lifestyle factors, health behaviors, menstrual/reproductive information and health care access and utilization were analyzed to assess their relations to mammogram underuse using unconditional logistic regression method.

RESULTS

The results showed that younger age, having no place to go when sick (OR = 2.2, 95% CI, 1.2-4.0), having no visits to a general doctor (OR = 1.7, 95% CI, 1.2-2.4) or medical specialist (OR = 2.2, 95% CI, 1.6-3.1) and having no influenza shot in last year (OR = 1.7, 95% CI, 1.2-2.3) increased the risk of underusing mammography screening among women who had a family history of breast or ovarian cancer. Women who had no home care from health professionals in the last year were less likely to underuse mammogram with an OR of 0.3 (95% CI, 0.1-0.6), compared with women who had.

CONCLUSION

Medical care-related factors may affect the use of mammography screening in women with a family history of breast or ovarian cancer.

Racial and ethnic disparities in breast cancer mortality: are we doing enough to address the root causes?

Breast cancer is the most common noncutaneous malignancy and the second most lethal form of cancer among women in the United States. Mortality from breast cancer has declined since the late 1980s, but this decline has been steeper among white women compared with black women. As a result, the black:white mortality rate ratio has increased over the last two decades. Other ethnic minorities also suffer from disproportionately high breast cancer mortality rates. This review discusses the causes of racial and ethnic disparities in breast cancer mortality and describes the most common approaches to reducing these disparities. The literature suggests that outcome disparities are related to patient-, provider-, and health system-level factors. Lack of insurance, fear of testing, delay in seeking care, and unfavorable tumor characteristics all contribute to disparities at the patient level. At the provider level, insufficient screening, poor follow-up of abnormal screening tests, and nonadherence to guideline-based treatments add to outcome disparities. High copayment requirements, lack of a usual source of care, fragmentation of care, and uneven distribution of screening and treatment resources exacerbate disparities at the health system level. Although pilot programs have increased breast cancer screening among select populations, persistent disparities in mortality suggest that changes are needed at the policy level to address the root causes of these disparities.

Presence of epithelial cells in nipple aspirate fluid is associated with subsequent breast cancer: a 25-year prospective study

Fluid and epithelial cells obtained from the breasts of non-pregnant, non-lactating women by nipple aspiration, can be used for early diagnosis of breast neoplasms. However, since nipple aspirate fluid (NAF) with cells is obtainable from less than half of women sampled, the question arises: Is this method capable of targeting the women most likely to develop breast cancer? We approached this question with a 25-year prospective study to determine if subjects yielding NAF with or without epithelial cells were more likely to develop breast cancer during the follow-up period than subjects from whom no NAF or epithelial cells were obtained. Logistic regression analysis was used to determine relative risk (RR) with 95% confidence intervals (CI). The follow-up cohort of 972 was representative of the eligible cohort of 1605 for factors related to breast cancer risk and nipple aspiration outcome, and representative of the general population for breast cancer risk. After a mean follow-up period of 25 years, women with epithelial cells in NAF were significantly more likely to develop breast cancer (RR=1.92; CI=1.22-3.01; p<or=0.005), especially invasive breast cancer (RR=2.27; CI=1.27-4.03; p<or=0.005), than women with no NAF, or NAF without epithelial cells. These risks were higher for women<55 years of age at the time of sampling (RR=2.1 for any breast cancer, 2.5 for invasive breast cancer). We conclude that presence of NAF with epithelial cells is associated with subsequent breast cancer risk and may be a useful marker for women at higher risk.

Literacy and knowledge, attitudes, and behavior about colorectal cancer screening

This cross-sectional survey explored the association between functional health literacy and knowledge of, beliefs and attitudes about, and reported usage of colorectal cancer screening tests. The results indicate that functional health literacy, as assessed by the Short Test of Functional Health Literacy in Adults (STOFHLA), is not an independent predictor of colorectal cancer screening knowledge, beliefs, attitudes, or behavior. Latino ethnicity and education, however, often predicted screening responses, suggesting that efforts to improve communication about colorectal cancer screening with Latino patients and patients with low education clearly are needed to reduce the disparities in awareness and utilization of colorectal cancer screening tests. This study also explored influences on intended screening behavior. Physician recommendation was found to be a powerful motivator of intention to undergo colorectal cancer screening regardless of literacy level, indicating that interventions aimed at increasing physician recommendation of colorectal cancer screening may be an effective way of increasing screening rates.

Breast self-examination practices among women from six ethnic groups and the influence of cancer worry

Diverse samples of women (N = 1364) from Brooklyn, New York, were interviewed regarding their breast cancer screening practices. Of interest here is the relation between cancer worry and adherence to breast self-examination (BSE) guidelines among the six ethnic groups identified--European American, African American, Haitian, Dominican and English-speaking Caribbean women. There was a significant difference in cancer worry by ethnicity. Logistic regression analysis indicated that education, cancer worry, and perceived efficacy of BSE significantly predicted adherence. Furthermore, there were significant differences among women of African descent in BSE adherence and cancer worry. These differences reflect the emerging need for researchers to empirically and methodically investigate ethnic and cultural factors, as well as emotions and affect in preventive health behaviors.

Toward a system of cancer screening in the United States: trends and opportunities

The hard work of public health officials, physicians, and disease advocacy groups to educate Americans about the importance of early detection has resulted in uptake of screening tests at levels equivalent to or higher than in countries with organized cancer screening programs. However, the societal costs of high screening rates are larger in the United States than in other countries, including higher prices for screening, more unnecessary testing, and inefficiencies in delivery, especially in small practices. Further, screening rates are not evenly distributed across population groups, and the national expenditure on clinical and community research to promote cancer screening among individuals has not been matched by research efforts that focus on policy or clinical systems to increase screening widely throughout the population. We identify opportunities for organizational change that improve access to use, improve quality, and promote cost effectiveness in cancer screening delivery.

Incorporating cultural constructs and demographic diversity in the research and development of a Latina breast and cervical cancer education program

BACKGROUND

Latino immigrants are at higher risk of death from breast and cervical cancer, necessitating effective cancer education interventions.

METHODS

Qualitative and quantitative information was obtained from Latinos from Arkansas and New York City through focus groups and questionnaires. Findings were analyzed using the PEN-3 model.

RESULTS

The results demonstrate a mechanism for creating a culturally competent program, Esperanza y Vida, through progressively analyzing the findings to define the key perceptions, enablers, and nurturers, then applying this information to construct program components to address appropriate health behavior and cultural components that address the specific needs of a diverse Latino population.

CONCLUSION

Finding a systematic approach to incorporating and embracing sociocultural perspectives and constructs may effectively appeal to diverse Latino immigrants in the development of a cancer education intervention.

Ethnic differences in predictors of hearing protection behavior between Black and White workers

The purpose of the study is to determine whether there are ethnic differences in predictors of hearing protection behavior between Black and White workers. The Predictors of Use of Hearing Protection Model (PUHPM) derived from Pender's Health Promotion Model (Pender, 1987) was used as a conceptual model. A total of 2,119 (297 Blacks, 1,822 Whites) were included in the analysis. Internal consistency of instrument items was assessed using theta reliability estimates. Significant predictors of the use of hearing protective devices (HPDs) for Black and White workers and differences in predictors between the two groups were examined using multiple regression with interaction terms. Ethnic differences in scale or individual item scores were assessed using chi-square and t-test analyses. Different factors influenced hearing protection behavior among Black and White workers. The model was much less predictive of Blacks' hearing protection behavior than Whites' (R2 = .12 vs. .36). Since the PUHPM was not as effective in predicting hearing protection behavior for Blacks as for Whites, future studies are needed to expand the PUHPM through qualitative study and to develop culturally appropriate models to identify factors that better predict hearing protection behavior as a basis for developing effective interventions.

Health beliefs, salience of breast cancer family history, and involvement with breast cancer issues: adherence to annual mammography screening recommendations

Involvement in breast cancer (BC) issues, and the degree to which family history of BC influences perceived risk (salience of family history), have been proposed as additions to the Health Belief Model as applied to mammography adherence. Barriers and benefits of mammography, perceived susceptibility, severity, cues to action, salience of family history, and issue involvement with respect to BC were examined in adherent (n=97) and non-adherent (n=213) women. Adherent women with positive family histories reported greater benefits of mammography, greater response to cues to action, and higher salience of family history than women with negative family histories. Non-adherent women with positive family histories reported fewer benefits of mammography and greater issue involvement, and perceived BC as less severe than those with negative family histories. Benefits (OR=1.51), susceptibility (OR=1.41), issue involvement (OR=1.59), severity (OR=0.66), and cues to action (OR=0.75) were significantly associated with adherence. Results have implications for evidence-based interventions.

Understanding the factors underlying disparities in cancer screening rates using the Peters-Belson approach: results from the 1998 National Health Interview Survey

BACKGROUND

Cancer screening rates vary substantially by race and ethnicity. We applied the Peters-Belson approach, often used in wage discrimination studies, to analyze disparities in cancer screening rates between different groups using the 1998 National Health Interview Survey.

METHODS

A regression model predicting the probability of getting screened is fit to the majority group and then used to estimate the expected values for minority group members had they been members of the majority group. The average difference between the observed and expected values for a minority group is the part of the disparity that is not explained by the covariates.

RESULTS

The observed disparities in colorectal cancer screening (5.88%) and digital rectal screening (8.54%) between white and black men were explained fully by the difference in their covariate distributions. Only half of the disparity in the observed screening rates (13.54% for colorectal and 17.47% for digital rectal) between white and Hispanic men was explained by the difference in covariates between the groups. The entire disparity observed in mammography screening rates for black and Hispanic women (2.71% and 6.53%, respectively) compared with white women was explained by the difference in covariate distributions.

CONCLUSIONS

We found that the covariates that explain the disparity in screening rates between the white and the black population do not explain the disparity between the white and the Hispanic population. Knowing how much of a health disparity is explained by measured covariates can be used to develop more effective interventions and policies to eliminate disparity.

Implications for breast and cervical cancer control for Latinas in the rural South: a review of the literature

The Latino population has more than tripled in six southern US states. Little research exists describing the Latino population in the rural South and the unique cancer control needs of this group. This article reviews existing literature on Latinas with a focus on rural southern settlement processes and applicable breast and cervical cancer control research. Recommendations for effective cancer control programs include developing special outreach efforts conducted with monolingual Latinas, incorporating important cultural components and values related to family, spirituality, and community, and designing programs that incorporate low-literacy materials and messages or that do not require literacy to participate. Understanding the social, cultural, and economic issues that Latinas face is an important first step in designing culturally relevant breast and cervical cancer control.

Rational choice(s)? Rethinking decision-making on breast cancer risk and screening mammography

Women who refrain from undergoing breast cancer screening are believed to be uninformed about risks and usually labeled as irrational. Our purpose in writing this paper is to challenge the traditional notion of rational behaviour, illustrating with qualitative data that people's rationality is influenced by their socio-cultural and political identities. We explore three major themes: (1) cultural explanations regarding intention to use screening mammography (2) (dis)trust in science and expert opinion, and (3) self-responsibility and self-surveillance in caring for one's body. Understanding that women rely on different risk discourses to make decisions about their health should aide researchers, health professionals, and the community in better understanding alternative ways of conceptualizing people's health-related behaviours when they do not coincide with health authorities recommendations.

Whatever happened to clinical breast examinations?

BACKGROUND

The purpose of this study was to examine trends in the use of clinical breast examinations (CBE), mammography, and both tests between the years 1990 and 2000.

METHODS

Receipt of breast cancer screening tests (CBE, mammography, and both tests combined) for white, black, and Hispanic women in 1990, 1994, 1998, and 2000 were examined by sociodemographic, access, and health risk indicators using data from the National Health Interview Survey.

RESULTS

The use of mammography increased from 1990 to 2000, but the proportion of women reporting a recent CBE decreased for almost all groups of women. Differential use of CBE by sociodemographic characteristics is consistent with what has been documented for mammography.

CONCLUSIONS

Although the use of mammography has increased since 1990, there has been a downward trend in the use of CBE. Healthcare providers should be aware of the lower rates of CBE, particularly among women with compromised access to health care, and should not assume that women who get mammograms have received comprehensive screening for breast cancer.

Development of cultural belief scales for mammography screening

PURPOSE/OBJECTIVES

To develop instruments to measure culturally related variables that may influence mammography screening behaviors in African American women.

DESIGN

Instrumentation methodology.

SETTING

Community organizations and public housing in the Indianapolis, IN, area.

SAMPLE

111 African American women with a mean age of 60.2 years and 64 Caucasian women with a mean age of 60 years.

METHODS

After item development, scales were administered. Data were analyzed by factor analysis, item analysis via internal consistency reliability using Cronbach's alpha, and independent t tests and logistic regression analysis to test theoretical relationships.

MAIN RESEARCH VARIABLES

Personal space preferences, health temporal orientation, and perceived personal control.

FINDINGS

Space items were factored into interpersonal and physical scales. Temporal orientation items were loaded on one factor, creating a one-dimensional scale. Control items were factored into internal and external control scales. Cronbach's alpha coefficients for the scales ranged from 0.76-0.88. Interpersonal space preference, health temporal orientation, and perceived internal control scales each were predictive of mammography screening adherence.

CONCLUSIONS

The three tested scales were reliable and valid. Scales, on average, did not differ between African American and Caucasian populations.

IMPLICATIONS FOR NURSING

These scales may be useful in future investigations aimed at increasing mammography screening in African American and Caucasian women.

The Delta project: increasing breast cancer screening among rural minority and older women by targeting rural healthcare providers

PURPOSE/OBJECTIVES

To test a multimethod approach designed for rural healthcare providers to increase breast cancer screening among low-income, African American, and older women.

DESIGN

Two-year experimental pretest/post-test with random assignment by group.

SETTING

Primary healthcare providers' offices.

SAMPLE

224 nurses, physicians, and mammography technicians.

METHODS

Standardized patients to observe and record healthcare providers' performances, followed by direct feedback, newsletters, posters, pocket reminder cards, and lay literature about screening to use in clinics.

MAIN RESEARCH VARIABLES

Healthcare providers' knowledge and attitudes as measured by survey responses, skills as measured by a checklist, and the provision of breast cancer screening as measured by mammography facilities' data.

FINDINGS

Healthcare providers significantly improved in demonstration of breast cancer screening practice after the intervention. Nurses performed significantly better than physicians on the breast examination during the post-test. More women older than 50 received mammograms in the experimental counties than in the comparison counties. Culturally sensitive lay literature is needed for African American women with low literacy.

CONCLUSIONS

Successful interventions included use of standardized patients to teach healthcare providers in their office settings, prompts such as posters and pocket reminder cards, and easy-to-read newsletters.

IMPLICATIONS FOR NURSING

Physicians and nurses play a powerful role in motivating women to have mammograms and clinical breast examinations and to practice breast self-examination. Interventions that help these providers fulfill that role should be implemented.

Comparison of mammography use by older black and white women

OBJECTIVES

To identify differences in the prevalence of ever having had a mammogram and having had a recent mammogram between older black and white women and to compare factors associated with mammography use in older black and white women.

DESIGN

Data analysis and comparative study using nationally representative multistage sampling survey.

SETTING

Data were obtained from the 1998 National Health Interview Survey.

PARTICIPANTS

Four hundred forty-nine black and 3,328 white older women were examined.

MEASUREMENTS

The outcome variables included never having had a mammogram (yes/no) and not having had a mammogram in the past 3 years (yes/no).

RESULTS

The results of chi-square tests showed that older blacks were less likely to have ever had a mammogram than older whites, but there was no difference in having had a recent mammogram between older blacks and whites. After adjusting for other related factors, race was not related to mammography use in older blacks and whites. Health insurance was related to mammography use in older whites but not in older blacks. Family income was associated with never having had a mammogram in older whites but not in older blacks. Older blacks with less than 12 years of education were less likely to have had a mammogram (recently or ever) than older whites with less than 12 years of education.

CONCLUSIONS

Even though race, per se, was not associated with mammography use in older black and white women, many barriers to mammography use between older black and white women were different or did not have similar effects. To promote mammography use in older black and white women, barriers need to be specifically targeted for each group to enhance the effectiveness of breast cancer screening programs.

Recruiting older African American men to a cancer screening trial (the AAMEN Project)

PURPOSE

This article describes the demographic characteristics of participants in a randomized trial (the AAMEN Project) designed to recruit older (aged 55+ years) African American men to a cancer screening trial.

DESIGN AND METHODS

The AAMEN Project is a recruitment trial developed for African American men aged 55+ years living in southeastern Michigan.

RESULTS

Of the 34,376 African American men in the study, 37.6% had low incomes and 62.4% had moderate-to-high incomes. The average age of the men was 63.3 years (SD = 5.9 years). Among men who were eligible and interested in participating, the proportion of men with low incomes was significantly greater than the proportion of men with moderate-to-high incomes (p <.001).

IMPLICATIONS

The AAMEN Project demonstrated success in recruiting a substantial proportion of men with low incomes as well as men with moderate-to-high incomes. These findings may facilitate the development of future recruitment efforts involving older African American men.

Mammography screening in African American women: evaluating the research

BACKGROUND

Notwithstanding some controversy regarding the benefits of screening mammography, it is generally assumed that the effects are the same for women of all race/ethnic groups. Yet evidence for its efficacy from clinical trial studies comes primarily from the study of white women. It is likely that mammography is equally efficacious in white and African American women when applied under relatively optimal clinical trial conditions, but in actual practice African Americans may not be receiving equal benefit, as reflected in their later stage at diagnosis and greater mortality.

METHODS

Initial searches of Medline using search terms related to screening mammography, race, and other selected topics were supplemented with national data that are routinely published for cancer surveillance. Factors that potentially compromise the benefits of mammography as it is delivered in the current health care system to African American women were examined.

RESULTS

While there have been significant improvements in mammography screening utilization, observational data suggest that African American women may still not be receiving the full benefit. Potential explanatory factors include low use of repeat screening, inadequate followup for abnormal exams, higher prevalence of obesity and, possibly, breast density, and other biologic factors that contribute to younger age at diagnosis.

CONCLUSIONS

Further study of biologic factors that may contribute to limited mammography efficacy and poorer breast cancer outcomes in African American women is needed. In addition, strategies to increase repeat mammography screening and to ensure that women obtain needed followup of abnormal mammograms may increase early detection and improve survival among African Americans. Notwithstanding earlier age at diagnosis for African American women, mammography screening before age 40 years is not recommended, but screening of women aged 40-49 years is particularly critical.

Strategies for increasing physicians', nurses', and mammography technicians' participation in research

BACKGROUND

Breast cancer screening in physicians' daily practices needs greater emphasis. Increasing provider participation in research in this area can be a challenge as demonstrated in our study to test interventions targeting rural health care providers.

METHOD

Recruitment methods for the randomized controlled trial involving 27 counties in the Mississippi River Delta region of Arkansas included the following: introductory letters and return postcards, mailed questionnaires, telephone calls, attendance at local medical staff meetings, and telephoning the primary care offices to set a time to meet the providers at their practice sites. This final recruitment strategy of telephoning the primary care offices and arranging with the office manager to bring a CME/CEU credit program included an on-site demonstration of a CBE technique and a free lunch.

RESULTS

Only the final strategy yielded provider participation for the study and was more successful in the experimental than the control counties. Providers in the control group could not receive the education program until after their post-test.

CONCLUSION

Successful approaches to enrolling physicians and nurses in a study involve careful use of their time and providing benefits.

Breast and cervical cancer screening among migrant and seasonal farmworkers: a review

Women constitute about one in five hired farmworkers in the US. Their health may be affected by exposure to unhealthy living and working conditions, by increased exposure to health hazards, by poverty, and by poor utilization of health care and preventive services. About 69% of migrant and seasonal farmworkers were born outside the US, mostly in Mexico and central America, and many speak little English. The health concerns of women who are migrant and seasonal farmworkers include breast and cervical cancer, which can be prevented or controlled through routine screening, but cancer incidence and mortality data for migrant workers are sparse. We reviewed published studies that examined breast and cervical cancer screening in this population. These studies include cross-sectional surveys, health needs assessments, and randomized and non-randomized intervention trials. A review of published studies of cancer screening among women who are migrant and seasonal farmworkers indicates that underutilization of mammograms and Papanicolau (Pap) tests among this population may stem from their limited awareness of the importance of cancer screening and cultural beliefs. Other barriers include cost, lack of health insurance, lack of transportation and child care difficulties. The extent to which results obtained in selected localities are generalizable to other settings is uncertain, but results to date provide important information about possible approaches for increasing cancer screening among women migrant farmworkers.

Breast and cervical cancer screening practices among Hispanic women in the United States and Puerto Rico, 1998-1999

BACKGROUND

Results from recent studies suggest that Hispanic women in the United States may underuse cancer screening tests and face important barriers to screening.

METHODS

We examined the breast and cervical cancer screening practices of Hispanic women in 50 states, the District of Columbia, and Puerto Rico from 1998 through 1999 by using data from the Behavioral Risk Factor Surveillance System.

RESULTS

About 68.2% (95% confidence interval [CI] = 66.3 to 70.1%) of 7,253 women in this sample aged 40 years or older had received a mammogram in the past 2 years. About 81.4% (95% CI = 80.3 to 82.5%) of 12,350 women aged 18 years or older who had not undergone a hysterectomy had received a Papanicolaou test in the past 3 years. Women with lower incomes and those with less education were less likely to be screened. Women who had seen a physician in the past year and those with health insurance coverage were much more likely to have been screened. For example, among those Hispanic women aged 40 years or older who had any health insurance coverage (n = 6,063), 72.7% (95% CI 70.7-74.6%) had had a mammogram in the past 2 years compared with only 54.8% (95% CI 48.7-61.0%) of women without health insurance coverage (n = 1,184).

CONCLUSIONS

These results underscore the need for continued efforts to ensure that Hispanic women who are medically underserved have access to cancer screening services.

Racial differences in breast cancer screening among women from 65 to 74 years of age: trends from 1987-1993 and barriers to screening

Breast cancer mortality is decreasing for elderly white women but increasing for elderly black women. National surveys were used to study racial differences in breast cancer screening and effects of Medicare funding for mammography and to examine explanatory fac- tors. A total of 13,545 women, aged 65-74, from the Health Care Finance Administration's Master Beneficiary File participated. After Medicare funding for screening mammography, the percent reporting a mammogram increased for white women, but not for black women. Clinical breast examination and breast self-examination decreased. Physician's recommendation, geographic area, education level and health status were the variables significantly affecting mammography usage for both races. Physicians recommended mammography more often if women were white, married, educated beyond high school and had an annual income greater than $20,000. These results support the need to design and test strategies specifically for black women and interventions to emphasize physician recommendations for breast cancer screening.

Factors related to cancer screening in Hispanics: a comparison of the perceptions of Hispanic community members, health care providers, and representatives of organizations that serve Hispanics

Hispanics have lower rates of screening for cervical, breast, and colon cancer than non-Hispanics. Activities to increase cancer screening in this population may not be informed by Hispanics, which may have implications for success rates of interventions. In this study, the perceptions about cancer screening behaviors in Hispanics are compared among three groups: a random sample of respondents (75% Hispanic) to a population-based survey, health care providers (primarily non-Hispanic), and representatives of organizations that serve Hispanics (36% Hispanic). While there was agreement that socioeconomic factors were important for cancer screening, differing views were expressed regarding the importance of cultural factors for cancer screening among Hispanics. Interventions developed by those who serve the Hispanic population may be based on inaccurate perceptions about the beliefs and practices of the population served. For effective interventions, it will be necessary to understand the factors important to Hispanics for cancer screening.

How the health care system can improve mammography-screening rates for underserved women: a closer look at the health care delivery system

The way care is delivered has dramatic impact on the patient-provider interaction and the outcomes experienced by the patient. This article explores a deceptively simple but very powerful method for evaluating and improving care delivery. Mammography is a routine screening procedure. However, many factors can influence how frequently women seek and obtain mammograms. Twenty-five low-income women identified empowering factors and barriers they experienced when trying to obtain a mammogram.

The role of inadequate health literacy skills in colorectal cancer screening

Colorectal cancer is ideally suited for early detection strategies that are likely to improve survival rates. Screening with either a fecal occult blood test (FOBT) or flexible sigmoidoscopy has been shown to identify precancerous polyps or cancers in early stages. However, persons with limited education and of lower socioeconomic status infrequently participate in screening programs in general and have very low rates of colorectal screening. Low literacy, which is common among persons with limited education and low income, may be an overlooked factor in understanding patients' decision making about colorectal cancer screening. This article provides information from focus groups about colorectal cancer screening, which we examine in the context of relevant literature on cancer screening and literacy. Using the health belief model, we examine the association between inadequate health literacy skills and low rates of colorectal cancer screening. The theoretical model also provides insights into strategies for improving knowledge, attitudes, and beliefs and screening rates for this challenging patient population.

Promoting breast and cervical cancer screening at the workplace: results from the Woman to Woman Study

OBJECTIVES

This article reports findings from a peer-delivered intervention designed to increase use of breast and cervical cancer screening.

METHODS

Twenty-six worksites were randomly assigned to the intervention or comparison group. The 16-month intervention consisted of group discussions, outreach, and educational campaigns. Data were collected from a random sample of women employees stratified by age (baseline n = 2943; final n = 2747). Cross-sectional analyses were conducted to evaluate the impact of the intervention on screening behaviors.

RESULTS

Relative to comparison worksites, the intervention group experienced greater increases in the percentage of women who reported a recent mammogram (7.2% vs 5.6%), clinical breast examination (5.8% vs 2.1%), and Papanicolaou (Pap) test (4.7% vs 1.9%). After worksite cluster and age strata were controlled for, the observed increase in Pap tests was significantly greater in the intervention group (odds ratio [OR] = 1.28; 95% confidence interval [CI] = 1.01, 1.62); however, differences in mammography screening rates (OR = 1.14; 95% CI = 0.90, 1.44) and clinical breast examination (OR = 1.19; 95% CI = 0.96, 1.49) were not statistically significant.

CONCLUSIONS

Intervention activities produced a modest increase in cervical cancer screening, but they did not accelerate breast cancer screening rates above the observed secular trend.

Breast cancer size and stage in Hispanic American women, by birthplace: 1992-1995

OBJECTIVES

This study examined whether Hispanic women with breast cancer have tumor characteristics associated with delayed detection and whether these characteristics vary by birthplace.

METHODS

Surveillance, Epidemiology, and End Results program data were used in examining breast cancer size and stage by racial/ethnic group and birthplace.

RESULTS

Hispanic women with breast cancer had a higher percentage of tumors larger than 1 cm (77.7%) than--non-Hispanic Whites (70.3%), as well as a higher percentage of tumors larger than 2 cm (45.9% vs 33.0%). Furthermore, in comparison with Hispanic women born in the United States, Hispanic American women born in Latin America had higher percentages of tumors larger than 1 cm (82.2% vs 75.2%) and larger than 2 cm (54.1% vs 41.7%).

CONCLUSIONS

These findings suggest that Hispanic women with breast cancer, especially first-generation Hispanic Americans, have a relative delay in the timeliness of their cancer diagnosis. First-generation Hispanic American women should be targeted in interventions designed to increase the use of breast cancer screening.

Participation of minorities in cancer research: the influence of structural, cultural, and linguistic factors

Overall, participation rates in cancer clinical trials are very low, ranging from 3 to 20% of eligible participants. However, participation rates are especially low among the socially disadvantaged and racial/ethnic minority groups that have been historically underrepresented in clinical research. Structural factors such as study duration, treatment or intervention schedule, cost, time, followup visits, and side effects represent more of a barrier to participation among these groups compared with white, non-Hispanics. Attitudes, beliefs, perceptions, and knowledge regarding clinical research, and cultural characteristics of underrepresented minorities pose additional barriers to participation. This article focuses on the structural, cultural, and linguistic factors that affect participation in clinical cancer research for each major U.S. racial/ethnic group. Low socioeconomic status, speaking a primary language other than English, differences in communication styles, mistrust of research and the medical system, fear, embarrassment, and lack of knowledge about the origin of cancer appear to have a negative impact on clinical cancer research participation rates. Much of the information about these factors comes from studies of cancer screening because little data is available on the factors that prevent and facilitate participation of minorities in clinical cancer trials specifically. Such research is needed, and, given the heterogeneity within and between minority populations, should occur in several different geographic settings and with as many different minority subpopulations as possible.

Socioeconomic Factors, not Ethnicity, Predict Breast Self-Examination

The American Cancer Society has recommended monthly breast self-examinations (BSEs) to aid in the early detection of breast cancer. Compliance with BSE recommendations has been shown to be decreased in certain ethnic groups. This investigation evaluates relevant variables involved in BSE compliance in an urban breast cancer screening center. A survey over a 1-year period (June 1996-June 1997) was given to all patients on their initial visit to the Breast Health Center at Tulane University Medical Center. Demographic and socioeconomic factors associated with the compliance of BSE were explored. The overall rate of BSE was relatively high at 80%. There was no difference between ethnic groups in rates of BSE (Caucasians 21% versus African Americans 20%). Statistically significant variables associated with BSE noncompliance were high school education (did not complete high school 16% versus completed high school 33%; p < 0.0004), employment status (employed 16% versus unemployed 31%; p < 0.0004), and marital status (married 15% versus single/divorced 22%; p < 0.05). While the majority of women in our study practiced BSE and ethnicity did not predict BSE, several socioeconomic factors were predictive of BSE compliance. Efforts to increase community outreach to lower socioeconomic patients as well as efforts to ensure proficient BSE techniques by patients may help detect early breast cancer.

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.
