The association of race/ethnicity,socioeconomic status,and physician recommendation for mammography: who gets the message about breast cancer screening?

OBJECTIVES: This study investigated the association between physician recommendation for mammography and race/ethnicity, socioeconomic status, and other characteristics in a rural population. METHODS: In 1993 through 1994, we surveyed 1933 Black women and White women 52 years and older in 10 rural counties. RESULTS: Fifty-three percent of the women reported a physician recommendation in the past year. White women reported recommendations significantly more often than did Black women (55% vs 45%; odds ratio = 1.49). Controlling for educational attainment and income eliminated the apparent racial/ethnic difference. After control for 5 personal, 4 health, and 3 access characteristics, recommendation for mammography was found to be more frequent among women who had access to the health care system (i.e., had a regular physician and health insurance). Recommendation was less frequent among women who were vulnerable (i.e., were older, had lower educational attainment, had lower annual family income). CONCLUSIONS: Socioeconomic status, age, and other characteristics--but not race/ethnicity--were related to reports of a physician recommendation, a precursor strongly associated with mammography use. Efforts to increase physician recommendation should include complementary efforts to help women address socioeconomic and other barriers to mammography use.     

Mammograms and healthcare access among US Hispanic and non-Hispanic women 40 years and older

Compared to non-Hispanic women, Hispanic women have disproportional mortality rates due to breast cancer. Mammographic screening detects breast cancer in its early stages and reduces mortality. We examined data obtained from the 2002 Behavioral Risk Factor Surveillance System questionnare using logistic regression analyses to study the relationships between demographic and healthcare factors and mammography use among Hispanic and non-Hispanic White women 40 years and older. Overall, the odds of ever having had a mammogram were similar among Hispanic and non-Hispanic White women (odds ratio = 1.2; 95% confidence interval = 0.9, 1.6), when adjusted for age, employment status, and other demographic variables. Having a personal physician and the type of healthcare facility typically used were associated with mammography use, regardless of Hispanic ethnicity. Although associations between mammography use and demographic factors were similar between ethnic groups, larger proportions of Hispanics had demographic characteristics that were negatively associated with mammography use. Establishing policies and mechanisms to provide all women with regular access to a personal physician or healthcare professional for their preventive and nonemergency healthcare needs may improve mammography use among both Hispanic and non-Hispanic White women. Similarly, reaching out to women who are uninsured and who use facilities other than physicians' offices for their healthcare needs may increase the use of mammography among both ethnic groups.     

Advancing social workers' responsiveness to health disparities: the case of breast cancer screening

This study provides the basis for customizing culturally responsive social work health promotion programs aimed at eliminating breast cancer screening and mortality disparities between white and African American women. Survey data collected from a random sample of 853 women in rural North Carolina were used to explore the impact of psychosocial factors, including cultural beliefs, on differences by race and age in behavioral intentions if a breast lump was found. Multivariate logistic regression analysis revealed that age and past mammography screening predicted the intention to get a mammogram, whereas physician communication about breast cancer risk, never having a mammogram, breast cancer worry, and religious beliefs about God's role in curing cancer influenced women's intentions to watch the lump for changes. Factors in both models did not account for racial differences. The findings can help social workers tailor more culturally respectful breast health interventions and have implications for the development of other efforts to eliminate health disparities.     

Breast cancer screening and health behaviors among African American and Caribbean Women in New York City

A telephone-based survey regarding breast cancer screening practices among 300 African American and Caribbean women age 40 and over in New York City revealed that while U.S.-born women had significantly different sociodemographic profiles (in terms of insurance status, marital status, educational attainment), they were no more likely to have had a mammogram than the foreign-born women. Adjusting for insurance status and source of care, women with a provider recommendation were 8 times more likely ever to have had a mammogram (AOR 8.01, 95%CI: 3.74-17.14). Among foreign-born Caribbean women in the U.S. for less than half their lives, only 52% ever had a provider recommend a mammogram, compared with 77% of U.S.-born women. The findings confirm previous reports of the importance of physician recommendation in increasing mammography screening among urban Black women, and suggest that efforts to reach Caribbean-born women with breast cancer screening messages should emphasize the important role of providers.     

Test-retest reliability of self-reported mammography in women veterans

BACKGROUND: Mammography self-report is used to monitor screening and evaluate intervention trends; however, few studies have examined reliability. METHODS: Reliability of self-reported lifetime number of mammograms, most recent mammogram date, and predictors of reliability were assessed using data from Project H.O.M.E. The study population was 2,494 women 52 years and over, listed in the U.S. National Registry of Women Veterans, with no history of breast cancer, who completed both baseline (2000-2002) and year 1 (2002-2003) surveys. RESULTS: Reliability of lifetime number of mammograms was 60.9% for exact consistency and 79.9% for consistency within one mammogram. Thirty-five percent was exactly consistent in reporting mammogram date; 55.6% was consistent within 3 months. Completing both surveys by mail and reporting fewer lifetime mammograms at baseline were positively associated with consistency of reporting lifetime number. White race/ethnicity, having a Bachelor's degree, reporting a health care provider's recommendation for a mammogram, having a screening mammogram, completing both surveys by mail, and being in the maintenance or action stages of change were associated with consistency in reporting date. CONCLUSIONS: Reliability varies with the measure of self-reported mammography. Likewise, predictors show different patterns of association with different definitions. Our findings call attention to the need for explicit definitions and measures of mammography use.     

Variation in mammographic breast density by race

PURPOSE: Because of the observed racial differences in risk of developing breast cancer, the authors conducted a study to determine the variation in breast density, a strong predictor of breast cancer risk, by race and age. METHODS: Study subjects were women enrolled in Group Health Cooperative of Puget Sound, Seattle, WA, aged 20-79 years, who had a screening mammogram between 6/1/96 and 8/1/97. Women with increased breast density (BI-RADS "heterogeneously dense" and "extremely dense") (n = 14,178) were compared to those with fatty breasts (BI-RADS "almost entirely fat" and "scattered fibroglandular tissue") (n = 14,323). Logistic regression was used with adjustment for age, parity, age at first birth, menopausal status, current use of hormone replacement therapy, and body mass index. RESULTS: The odds ratio (OR) for having dense breasts versus fatty breasts, comparing Asian to White women, increased from 1.2 [95% confidence interval (CI) 0.9-1.6] for women age <45 to 1.6 (95% CI 1.3-2.2) for women over 65. Conversely, the OR for Black compared to White women was highest for the women age 65 and younger (OR 1.7 (1.2-2.3), 1.3(1.0-1.7), and 1.7 (1.2-2.3) for women age <45, 46-55, and 56-65, respectively), whereas Black women over 65 had similar density as Whites. Hispanic women had similar density compared to Whites for all ages. CONCLUSIONS: These racial differences in breast density generally do not conform to differences in race and age-specific breast cancer incidence rates.     

Contextual analysis of breast and cervical cancer screening and factors associated with health care access among United States women, 2002

This research explored the relationships between race/ethnicity and area factors affecting access to health care in the United States. The study represents an advance on previous research in this field because, in addition to including data on rurality, it incorporates additional contextual covariates describing aspects of health care accessibility. Individual-level data were obtained from the 2002 Behavioral Risk Factor Surveillance System (BRFSS). The county of residence reported by BRFSS respondents was used to link BRFSS data with county-level measures of health care access from the 2004 Area Resource File (ARF). Analyses of mammography were limited to women aged 40 years with known county of residence (n=91,492). Analyses of Pap testing were limited to women aged 18 years with no history of hysterectomy and known county of residence (n=97,820). In addition to individual-level covariates such as race, Hispanic ethnicity, health insurance coverage and routine physical exam in the previous year. We examined county-level covariates (residence in health professional shortage area, urban/rural continuum, racial/ethnic composition, and number of health centers/clinics, mammography screening centers, primary care physicians, and obstetrician-gynecologists per 100,000 female population or per 1000 square miles) as predictors of cancer screening. Both individual-level and contextual covariates are associated with the use of breast and cervical cancer screening. In the current study, covariates associated with health care access, such as health insurance coverage, household income, Black race, and percentage of county female population who were non-Hispanic Black, were important determinants of screening use. In multivariate analysis, we found significant interactions between individual-level covariates and contextual covariates. Among women who reside in areas with lower primary care physician supply, rural women are less likely than urban women to have had a recent Pap test. Black women were more likely than White women to have had a recent Pap test. Women with a non-rural county of residence were more likely to have had a recent mammogram than rural women. A significant interaction was also found between individual-level race and number of health centers or clinics per 100,000 population (p-value=0.0187). In counties with 2 or more health centers or clinics per 100,000 female population, Black women were more likely than White women to have had a recent mammogram. A significant interaction was also observed between the percentage of county female population who were Hispanic and the percentage who were non-Hispanic Black.     

Mammography rates for 20 community-based family practices in Ontario: a full practice audit

BACKGROUND: Many Canadian women 50 to 69 years of age do not have a mammogram within the recommended screening interval of every two years. Recent data suggest that over 50% of Canadian women did not have a time-appropriate mammogram and that not having a family physician was a significant factor associated with suboptimal screening. This study reviewed medical charts of 20 family physicians' practices to examine their mammography screening patterns. METHODS: Medical charts of all women between 52 and 71 years of age in 20 family practices were examined for mammography reports between September 2003 and June 2004. RESULTS: Across the 20 practices, 3,430 charts of eligible women 52 to 71 years of age were reviewed (mean per practice = 173 women; ranging from 38 to 385). The two-year time-appropriate mammography rate was 58.8%. The screening rates ranged from 25% to 76% across 20 practices. Four practices attained a 70% or greater time-appropriate screening rate. When we extended the time-appropriate frame to 36 months, the overall mammography rate increased to 70.0%. Practice size, method of remuneration for patient care, use of an electronic medical record, gender or age of physician, practice setting, use of Ontario Breast Screening Program (OBSP) were not found to be significantly associated with mammography screening rates. INTERPRETATION: Mammography rates within the recommended two-year interval for women who have a regular family physician are suboptimal. The rates for women in this study, all of whom have a family physician, were only slightly higher than those reported elsewhere for women without one. Further studies are required to uncover and overcome barriers to optimal mammography screening rates.     

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.     

How Old are African American Women When they Receive their First Mammogram? Results from a Church-Based Study

African American women in the U.S. have the highest breast cancer mortality though not the highest breast cancer incidence. This high mortality rate has been attributed in part to discrepancies in screening between African American and White women. Although this gap in mammography utilization is closing, little is known about what has been and is driving the screening practices of African American women, in particular age at first mammogram. This study examined the rates of breast cancer screening in an African American community sample from eight churches in greater Baltimore, Maryland and investigated the association between various factors and age at first mammogram. Participants were 213 women ages 22-89 years. About 77% of women had ever had a mammogram. Over 40% had their first mammogram before age 40. Women who first screened before age 40 had greater odds than women who had never screened of being knowledgeable about screening guidelines, of having received a physician recommendation to screen, and of having three or more female relatives who had been screened. Women who first screened at or after age 40 were more likely to have stronger religious beliefs of health than women who never had screened. These findings suggest the importance of reinforcing factors in screening behavior for African American women and have implications for physician training and public health education about breast cancer screening. A better understanding of African American women's mammography practice including early screening is needed to reduce this population's disproportionate breast cancer mortality risk.     

Mammography screening and differences in stage of disease by race/ethnicity

OBJECTIVES: We examined the effect of routine screening on breast cancer staging by race/ethnicity. METHODS: We used a 1990 to 1998 mammography database (N = 5182) of metropolitan Denver, Colo, women to examine each racial/ethnic cohort's incident cancer cases (n = 1902) and tumor stage distribution given similar patterns of routine screening use. RESULTS: Regardless of race/ethnicity, women participating in routine screenings had earlier-stage disease by 5 to 13 percentage points. After control for possible confounding factors, White women were more likely to have early-stage disease compared with Black and Hispanic women. CONCLUSIONS: Lack of screening coverage in certain racial/ethnic populations has often been cited as a reason for tumor stage differences at detection. In this study, correcting for screening did not completely reduce stage differentials among Black and Hispanic women.     

Racial/Ethnic Differences in the Self-Reported Use of Screening Mammography

The efficacy of mammography in reducing breast cancer mortality among women 50–69 years of age has been demonstrated in randomized controlled studies, but many women, especially ethnic minorities, have not been receiving regular mammographic screening. The current study investigated racial/ethnic differences in mammography use and their association with demographic characteristics and other factors. The study population consisted of 4,444 women aged 40 years and older who participated in the1996 Medical Expenditure Panel Survey. Outcome measures studied included the self-reporting of mammography within the past two years and past year. Multivariate logistic regression modeling was used to examine the effect of race while controlling for other factors. In the univariate analysis, there was virtually no difference between white, black, and Hispanic women in mammography rates within either one or two years. However, multivariate logistic regression suggested that both blacks and Hispanics were more likely than whites to have received recent mammography, as black women were 31% and Hispanic women were 43% more likely than white women to have had a mammogram within the previous two years. Our results suggest that white women are no longer more likely to receive periodic screening mammography than black and Hispanic women, and in fact, might even be less likely to undergo the procedure. This reversal might indicate, at least in part, that programs and other activities to promote screening mammography among ethnic minority women have been successful and should now be expanded to include other women.     

Knowledge,perceptions, and mammography stage of adoption among older urban women

Introduction: Mammography is under-used among older minority women. Identifying differences in their attitudes and beliefs by stage of mammography adoption will guide interventions for these under-studied and under-served women.Methods: A total of 253 older urban women were interviewed, assessing breast cancer knowledge, perceived mammography benefits and barriers, stage of mammography adoption, personal experience with breast cancer, physical and cognitive functioning, smoking status, source and frequency of regular medical care, and demographics. Analyses compared scale scores and individual items by stage of mammography adoption. Multivariate analysis used linear and logistic regression with stepwise model selection.Results: Sample mean age was 72.5 years; 88% were African American. About half (52%) had had a mammogram within the past 2 years (i.e., action stage of mammography adoption). Of the rest, 16% were thinking about having a mammogram in the next 6 months (contemplators) and 32% were not thinking about having a mammogram within 6 months (precontemplators). Knowledge and benefit scores were lowest for precontemplators. Overall barrier scores were highest for precontemplators (P < .001), but contemplators were most likely to worry about finding a lump (P < .05). Lower perceived barriers, provider recommendation, regular medical care somewhere other than a private physician's office, and age <75 years were independently associated with more favorable mammography stage (R² = .47).Conclusion: Mammography interventions for older urban women should combine provider recommendations with barrier-reducing interventions. Knowledge is associated with mammography contemplation, but barriers may affect whether contemplation leads to action. Precontemplators may need explanation of the rationale for screening; contemplators may need intervention to assuage fears.     

Primary care physicians' assessments of older patients' health and psychological status and recommendation of mammography

BACKGROUND: Recommendation of mammography may be particularly important for older women; nevertheless, physicians are less likely to recommend mammography to older women. Our objective was to examine the characteristics of older patients for whom primary care physicians recommend mammography. METHODS: Two hundred sixteen women aged 65 to 80 years were screened for depressive symptoms in primary care offices and invited to participate. They then completed a baseline in-home assessment between 2001 and 2003. At the time of the baseline in-home assessment, mammogram use and psychological status were assessed with commonly used and validated standard questionnaires. At the time of the index visit, physicians were asked to provide assessments of the patients. RESULTS: Patient-reported physician recommendation of mammography was more likely among patients the physicians rated as anxious than among patients the physicians rated as not being anxious (unadjusted odds ratio, 2.08; 95% confidence interval, 1.10-3.94). In multivariate models that controlled for physician ratings of knowledge of the patient, the association between physician rating of anxiety with patient-reported physician recommendation of mammography remained significant. Patient-reported physician recommendation of mammography was not significantly more likely among patients the physicians rated as depressed than among patients the physicians rated as not being depressed (unadjusted odds ratio, 1.57; 95% confidence interval, 0.86-2.85). CONCLUSIONS: Identification of anxiety may influence the recommendation of mammography among primary care physicians. An understanding of factors that influence the recommendation of mammography by primary care physicians may have important implications for interventions to improve rates of mammography use among older women.     

Racial Differences in Physician Recommendation of Hormone Replacement Therapy

PURPOSE: Previous studies have suggested that black women may be less likely than white women to be offered and to take hormone replacement therapy (HRT). Thus, race and other factors associated with physician recommendation of HRT that may influence women's decisions about HRT were examined. METHODS: Data were from a baseline assessment of participants in a randomized controlled trial designed to evaluate the efficacy of a tailored decision-aid on HRT decision-making. We telephone interviewed 581 Durham women ages 45-54. The association of race and other factors with reported physician recommendation of HRT was tested using chi(2) and logistic regression analysis. RESULTS: Overall, 45% of women surveyed reported that their physician recommended HRT; black women were significantly less likely than white women to report being advised about HRT (35% vs. 48%, respectively, P < 0.005). Additional factors associated with being recommended HRT included older age, being postmenopausal, having had a hysterectomy, having thought about the benefits of HRT, and being satisfied with information about HRT. CONCLUSIONS: Black women are less likely than white women to receive physician recommendation of HRT. Racial differences in patient-provider communication about HRT exist and thus require greater diligence on the part of health care providers to minimize such a gap.     

Competing demands in the office visit: what influences mammography recommendations?

BACKGROUND: The multiple competing demands of the busy office visit have been shown to interfere with delivery of preventive services. In this study we used physician recommendations for screening mammography to examine the relative importance of physician, patient, and visit characteristics in determining on which patient visits this preventive service will be provided. METHODS: Physicians in the Ambulatory Sentinel Practice Network (ASPN) completed a questionnaire describing their knowledge, attitudes, and beliefs about screening mammography. They also described the content of a series of nonacute care visits with women aged 40 to 75 years with regard to making a recommendation when the patient was due for screening mammography. The data were linked, and univariate and multivariate logistic regression methods were used to examine the relative importance of physician, patient, and visit characteristics on making a recommendation for mammography. RESULTS: Ninety-three physicians reported making a recommendation for screening mammography on 53.1% of nonacute visits. When modeling physician, patient, and visit characteristics separately, 70% of the variability in the model is explained by physician characteristics only, 63% by patient characteristics only, and 73% by visit characteristics only. A combined model using all characteristics explained 85% of the variability. CONCLUSIONS: Although characteristics of physicians and patients can predict frequency of recommendations for mammography, the specific characteristics of the visit are equally important. Efforts to improve delivery of preventive services in primary care that emphasize physician education and performance feedback are unlikely to increase rates of mammography recommendation. Effective strategies must consider the multiple competing demands faced by patients and physicians during each office visit and seek ways for assisting them in setting rational priorities for services.     

Breast cancer screening utilization by Latina community health center clients

Studies have demonstrated the importance of cost constraintsand cultural differences on the receipt of health services.Characteristics of health services delivery systems have alsobeen shown to influence the use of services by the poor. Thisstudy reports on the status of breast cancer screening experienceand factors associated with utilization in women clients ofan urban community health center. The clients were predominantlyof Latina origin, had an eighth-grade education or less andreported an income of $5000 or less. Nevertheless, 75% had hada clinical breast exam (CBE) in the past year and 59% had everhad a mammogram. However, few women had received regular screeningby mammography. In addition to physician recommendation anddiscussion with a doctor or nurse, previous breast problemsand the belief that most women over 50 get mammograms were associatedwith ever having had a mammogram. Insurance and entitlementcoverage was very important to mammography experience. Findingsreinforce the importance of investigating delivery system factorswhen assessing utilization and underscore the important roleproviders play in initiating discussion of screening needs andencouraging regular screening.     

Repeat mammography among women over 50 years of age.

Mammography decreases mortality among women 50 years of age and older. Although recent surveys show that mammography use has increased since 1983, it continues to be underused by women at risk for breast cancer. The frequency of repeat screening at recommended intervals remains an important unanswered question. This record audit study included all visits from 1986 to 1988 for active female patients, 51-64 years of age, in a family medicine practice. The practice has a disproportionately black patient population, many of whom are on public assistance, characteristics associated with lower compliance with cancer screening guidelines. I reviewed medical records for a physician's recommendation for mammography and also for a radiology report documenting receipt of the mammogram. I also abstracted from the medical record the reason for mammography, a history of breast cancer risk factors, and sociodemographic information. In addition, I noted documentation of a clinical breast examination (CBE) and CBE results. Records for 150 patients were included in the analysis. The results indicate that repeat screening mammography is not common: 3% had three mammograms during the study period; 19% had two; 33% had one; and 44% had none. Physician recommendation for first-time mammography and clinical examination occurred with low frequency. As others report, mammography use is strongly associated with physician recommendation for a mammogram.     

Compliance with mammography guidelines: physician recommendation and patient adherence

BACKGROUND: Guidelines recommend that women ages 50-75 years receive screening mammography every 1-2 years. We related receipt of physician recommendations for mammography and patient adherence to such recommendations to several patient characteristics. METHODS: We retrospectively reviewed medical records of 1,111 women ages 50-75 attending three clinics in an urban university medical center. We ascertained overall compliance with mammography guidelines and two components of compliance: receipt of a physician recommendation and adherence to a recommendation. Outcome measures were the proportion of patients demonstrating each type of compliance and adjusted odds ratios, according to several patient-related characteristics. RESULTS: Overall, 66% of women received a recommendation. Of women receiving a documented recommendation, 75% adhered. Factors showing significant positive associations with receiving a recommendation included being a patient in the general internal medicine clinic, having private insurance, visiting the clinic more often, and having a recent Pap smear. Patient adherence was positively associated with private insurance and Pap smear history, negatively associated with internal medicine, and not associated with visit frequency. CONCLUSIONS: Patient factors influencing physician mammography recommendations may be different from those associated with patient adherence, except for having private health insurance, which was a predictor of both.     

Baseline predictors of initiation vs. maintenance of regular mammography use among rural women

BACKGROUND: Predictors of regular mammography screening over many years have not often been examined prospectively. We used data from baseline (1993-1994), first (1996-1997), and second follow-up (2000) interviews with 336 White and 314 African-American rural women in the North Carolina Breast Cancer Screening Program to evaluate baseline factors predictive of regular mammography use over 7 years. METHODS: We defined regular mammography use as a recent mammogram (past 2 years) at all three interviews. Using binomial and logistic regression models adjusted for age, we examined factors associated with initiation (for women without prior regular use) and maintenance (for women with prior regular use) of mammography. RESULTS: Younger age and White race were predictive of initiation of regular mammography use. Physician recommendation was the strongest predictor of both initiation and maintenance of regular mammography use. Positive mammography attitudes and fewer personal barriers were strongly associated with initiation but not with maintenance. CONCLUSIONS: Increased contact with providers and greater support for screening mammograms by providers could have an important impact on rural women initiating and maintaining regular mammography screening. Special efforts are needed to prompt rural African-American women and those over age 65 to initiate screening, since once they start they are likely to continue.
