Breast and cervical cancer screening among low-income women in Nebraska: findings from the Every Woman Matters program, 1993-2004

OBJECTIVE: To examine the likelihood of enrollees in the Nebraska Every Woman Matters program being screened for breast and cervical cancer. METHODS: We explored the relationship between sociodemographic characteristics and receiving cancer screening services. RESULTS: Older and Native American women were more likely than younger and White women to have mammograms ordered [adjusted odds ratio (OR)=1.41, 95% confidence interval (CI) 1.08, 1.85]. African American [OR=0.54, 95% CI 0.46, 0.64] and Native American women [OR=0.47, 95% CI 0.39, 0.55] were less likely than White women to have clinical breast exams performed. Native American [OR=0.19, 95% CI 0.16, 0.23] and African American women [OR=0.56, 95% CI 0.46, 0.68] were less likely than White women to have a Pap test performed. CONCLUSION: Receiving cancer screening services was related to race; thus, understanding barriers for screening for minority women is warranted.     

Racial and ethnic differences in adjuvant hormonal therapy use

Abstract Background: In the United States, 5-year breast cancer survival is highest among Asian American women, followed by non-Hispanic white, Hispanic, and African American women. Breast cancer treatment disparities may play a role. We examined racial/ethnic differences in adjuvant hormonal therapy use among women aged 18-64 years, diagnosed with hormone receptor-positive breast cancer, using data collected by the Northern California Breast Cancer Family Registry (NC-BCFR), and explored changes in use over time. Methods: Odds ratios (OR) comparing self-reported ever-use by race/ethnicity (African American, Hispanic, non-Hispanic white vs. Asian American) were estimated using multivariable adjusted logistic regression. Analyses were stratified by recruitment phase (phase I, diagnosed January 1995-September 1998, phase II, diagnosed October 1998-April 2003) and genetic susceptibility, as cases with increased genetic susceptibility were oversampled. Results: Among 1385 women (731 phase I, 654 phase II), no significant racial/ethnic differences in use were observed among phase I or phase II cases. However, among phase I cases with no susceptibility indicators, African American and non-Hispanic white women were less likely than Asian American women to use hormonal therapy (OR 0.20, 95% confidence interval [CI]0.06-0.60; OR 0.40, CI 0.17-0.94, respectively). No racial/ethnic differences in use were observed among women with 1+ susceptibility indicators from either recruitment phase. Conclusions: Racial/ethnic differences in adjuvant hormonal therapy use were limited to earlier diagnosis years (phase I) and were attenuated over time. Findings should be confirmed in other populations but indicate that in this population, treatment disparities between African American and Asian American women narrowed over time as adjuvant hormonal treatments became more commonly prescribed.     

Cigarette smoking, alcohol consumption, and screening mammography among women ages 50 and older

BACKGROUND: The associations among cigarette smoking and alcohol consumption with recent screening mammograms were evaluated among women ages 50 years and older. METHODS: The sample included 946 white and African-American women ages 50 years and older from the 1995 Maryland Behavioral Risk Factor Survey. Bivariate and logistic regression analyses were performed to evaluate the associations between current cigarette smoking and alcohol consumption in the past month (none, 1-7 drinks, >7 drinks) with obtaining a screening mammogram in the past 2 years (recent mammogram), controlling for sociodemographic and health variables. RESULTS: Seventy-eight percent of respondents had recent mammograms, 15% smoked cigarettes, 18% reported 1-7 drinks, and 12% reported >7 drinks in the past month. Smokers had lower mammography rates than nonsmokers (odds ratio (OR) = 0.47, 95% confidence interval (CI) = 0.30-0.75). Women who drank alcoholic beverages had higher mammography rates than nondrinkers (OR = 1.37, 95% CI = 1.03-1.83). Smokers had the lowest mammography rates, regardless of their consumption of alcohol. An interaction was observed among white but not African-American women: nonsmokers who consumed moderate amounts of alcohol (1-7 drinks) had the highest mammography rates in this subgroup. CONCLUSIONS: To reduce breast cancer mortality, it is important to increase screening mammography among all women over age 50 and especially among smokers and the oldest women.     

Predisposing and Enabling Factors Associated with Mammography Use Among Hispanic and Non-Hispanic White Women Living in a Rural Area

ABSTRACT:  Context: Women who do not receive regular mammograms are more likely than others to have breast cancer diagnosed at an advanced stage. Purpose: To examine predisposing and enabling factors associated with mammography use among Hispanic and non-Hispanic White women. Methods: Baseline data were used from a larger study on cancer prevention in rural Washington state. In a sample of 20 communities, 537 women formed the sample for this study. The main outcomes were ever having had a mammogram and having had a mammogram within the past 2 years. Findings: Reporting ever having had a mammogram was inversely associated with lack of health insurance (OR = 0.37, 95% CI: 0.16-0.84), ages under 50 years (OR = 0.23, 95% CI: 0.12-0.45), high cost of exams (OR = 0.48, 95% CI: 0.27-0.87), and lack of mammography knowledge (OR = 0.16, 95% CI: 0.07-0.37), while increasing education levels were positively associated (OR = 1.72, 95% CI: 1.09-2.70). Reporting mammography use within the past 2 years was inversely associated with ages under 50 years (OR = 0.49, 95% CI: 0.27-0.88) and over 70 years (OR = 0.47, 95% CI: 0.24-0.94), lack of health insurance (OR = 0.23, 95% CI: 0.10-0.50), and high cost of exams (OR = 0.55, 95% CI: 0.35-0.87). Conclusions: Continued resources and programs for cancer screening are needed to improve mammography participation among women without health insurance or low levels of education.     

Receipt of mammography among women with intellectual disabilities: Medical record data indicate substantial disparities for African American women

BackgroundLittle information exists on the receipt of mammography by African American women with intellectual disabilities. Given the high rates of mortality from breast cancer among African American women and low screening rates among women with intellectual disabilities, it is important to understand the health screening behavior of this population.ObjectiveWe compared rates of mammography receipt among African American and White women with intellectual disabilities (n = 92) living in community settings in one Southeastern state in the United States.MethodData were collected from women's medical records or abstraction forms obtained from medical practices. Multivariate logistic regressions were modeled for receipt of mammography in one year, one of two years, or both study years (2008– 2009). Covariates included the women's age, living arrangement, severity of impairment, and urban/rural residence location.ResultsIn 2009, 29% of African American women and 59% of White women in the sample received mammograms. Similar disparities were found for receipt of mammography in either 2008 or 2009 and both 2008 and 2009. These disparities persisted after inclusion of model covariates. White women with intellectual disabilities received mammograms at adjusted rates that were nearly three to five times higher than African American women.ConclusionAfrican American women with intellectual disabilities receive mammography at significantly lower rates than White women with intellectual disabilities. Assertive measures to improve the screening rates for African American women with intellectual disabilities are urgently needed.     

The influence of breast self-examination on subsequent mammography participation

OBJECTIVES: We evaluated whether breast self-examination (BSE) influences subsequent mammography participation. METHODS: We evaluated associations between BSE and subsequent mammography participation, adjusting for baseline screening behaviors and sociodemographic, health, and lifestyle characteristics, among women aged 40 years and older using data from the longitudinal Canadian National Population Health Survey. RESULTS: Regular performance of BSE at baseline was not associated with receipt of a recent mammogram at follow-up among all women (adjusted odds ratio [OR]=1.01; 95% confidence interval [CI]= 0.75, 1.35) or with mammography uptake among the subgroup of women reporting never use at baseline (adjusted OR=0.78; 95% CI=0.50, 1.22). CONCLUSIONS: The lack of association between performance of BSE and subsequent mammography participation suggests that not recommending BSE is unlikely to influence mammography participation.     

Breast cancer screening behaviors among African American women with a strong family history of breast cancer

BACKGROUND: Despite the importance of breast cancer screening to reduce morbidity and mortality, limited information is available on screening practices among African American women with a family history that is suggestive of hereditary breast cancer. OBJECTIVES: To describe adherence to breast cancer screening recommendations among African American women with a family history that is suggestive of hereditary disease. METHODS: Participants were unaffected African American women (n=65) who had a family history of cancer that was suggestive of hereditary breast cancer. Breast cancer screening practices were evaluated by self-report. The study was conducted at the University of Pennsylvania in Philadelphia, PA. Women were recruited to participate in the study from February 2003-December 2005. RESULTS: Most women were adherent to recommendations for mammography (75%) and CBE (93%). A sizeable minority of women (41%) also performed excessive BSE. Being older than age 50 was associated significantly with mammography adherence (FET<0.05). Employment had a significant independent association with BSE; unemployed women were most likely to perform excessive BSE (OR=3.28, 95% CI: 1.05, 10.21, p<0.05). CONCLUSIONS: The results of this study suggest a complex pattern of breast cancer screening practices among African American women at increased risk for hereditary breast cancer.     

Prevalence and Determinants of Repeat Mammography Among Women from a Developing Country

Failures in repeat mammography decrease the potential benefits of screening; however, it is notable that the recent use of mammography is more frequently studied than repeat use. We estimated the prevalence and analyzed determinants for repeat mammography among women from Mexico, a developing country of Latin America. It was a two-stage study with an initial cross-sectional design (n?=?1045) and a final case-control design that involved women of at least 45 years of age with no history of breast, ovarian, or uterine cancer. Case subjects were those with three or more mammograms in the last 5 years, with the last one carried out within the last two years (n?=?444); control subjects included those who underwent ≥3 mammograms throughout their life with the most recent carried out >2 years ago (n?=?444). Through interviews, we evaluated context-dependency, fulfillment of expected outcomes, self-efficacy, and risk perception, among other factors. We estimated the prevalence with 95?% confidence intervals (CI), and odds ratios (OR) using multivariate binary logistic regression. The prevalence of repeat mammography was 40.4?% (95?% CI 37.4–43.4). Self-efficacy demonstrated the highest effect on repeat use (OR 7.7, 95?% CI 4.7–12.6), followed by awareness context-dependency (OR 4.9, 95?% CI 3.3–7.2), the use of Papanicolaou testing (OR 3.5, 95?% CI 2.3–5.2), the fulfillment of expected waiting time outcome (OR 2.4, 95?% CI 1.2–4.7), and context-dependency related to self-referral/health provider referral (OR 2.4, 95?% CI 1.7–3.4), independent of risk perception, age, education, and positive emotional state of mind. The study showed a need for increasing the prevalence of promoting awareness of the determining factors of repeat mammography, which is a necessary component in the early detection of breast cancer.     

Rate of breast cancer diagnoses among postmenopausal women with self-reported breast symptoms

BACKGROUND: Breast cancer rates in women with multiple breast symptoms have not been well described. METHODS: We examined the association between self-reported symptoms (lump, nipple discharge, pain, other) and breast cancer risk for screening and diagnostic mammograms in 57,681 women. Subanalyses evaluated risk among women with no prior mammograms, new symptoms, and repeated symptoms. One thousand, three hundred and eighty-nine women were diagnosed with cancer within 12 months of their mammograms. We calculated the breast cancer rate for each symptom and odds ratios (OR) with 95% confidence intervals (CI) for breast cancer among symptomatic women compared with asymptomatic women. RESULTS: Women reporting a lump had an increased odds of breast cancer compared with asymptomatic women (OR for diagnostic examination = 2.8, 95% CI = 2.3 to 3.4; OR for screening examination = 3.6, 95% CI = 2.6 to 5.0). No other symptoms were associated with breast cancer after controlling for a reported lump. A new lump at a diagnostic examination was significantly predictive of cancer among women with no prior mammograms (OR = 12.2, 95% CI = 2.8 to 53.5); reporting symptoms at 2 successive exams had little effect on breast cancer risk (OR for lump = 1.2, 95% CI = 0.6 to 2.5). CONCLUSIONS: Having a lump is the most predictive symptom of breast cancer whether it is reported at a screening or diagnostic examination or in conjunction with other symptoms.     

Lower adherence to screening mammography guidelines among ethnic minority women in America: a meta-analytic review

OBJECTIVE: This study investigates the association between ethnic minority status and receiving a screening mammogram within the past 2 years among American women over 50. METHOD: The findings from 33 studies identified from interdisciplinary research databases (1980 to 2006) were synthesized. Separate pooled analyses compared white non-Hispanics to African Americans (28 outcomes), Hispanics (18 outcomes), and Asian/Pacific Islanders (10 outcomes). RESULTS: Using the random effects model, results showed that African Americans were screened less than white non-Hispanics at a marginal level (OR 0.87, 95% CI 0.75, 1.00). Larger and significant discrepancies were observed for Hispanics (OR 0.65, 95% CI 0.50, 0.85) and Asian/Pacific Islanders (OR 0.63, 95% CI 0.39, 0.99) compared to white non-Hispanics. However, among studies controlling for socioeconomic status, ethnic differences in mammography screening were no longer significant for African Americans (OR 1.05, 95% CI 0.71, 1.76), Hispanics (OR 1.08, 95% CI 0.64, 1.93), or Asian/Pacific Islanders (OR 1.08, 95% CI 0.64, 1.93). Subgroup analyses further showed that geographical region, sampling method, and data collection strategy significantly impacted results. CONCLUSIONS: This study found evidence that ethnic minority-screening mammography differences exist but were impacted by socioeconomic status. Implications for interpreting existing knowledge and future research needs are discussed.     

Breast Cancer Treatment among African American Women in North St. Louis,Missouri

Similar to disparities seen at the national and state levels, African American women in St. Louis, Missouri have higher breast cancer mortality rates than their Caucasian counterparts. We examined breast cancer treatment (regimens and timing) in a sample of African American breast cancer patients diagnosed between 2000 and 2008 while residing in a North St. Louis cluster (eight zip codes) of late stage at diagnosis. Data were obtained from medical record extractions of women participating in a mixed-method study of breast cancer treatment experiences. The median time between diagnosis and initiation of treatment was 27 days; 12.2 % of the women had treatment delay over 60 days. These findings suggest that treatment delay and regimens are unlikely contributors to excess mortality rates for African American women diagnosed in early stages. Conflicting research findings on treatment delay may result from the inconsistent definitions of treatment delay and variations among study populations. Breast cancer treatment delay may reduce breast cancer survival; additional research is needed to better understand the points at which delays are most likely to occur and develop policies, programs, and interventions to address disparities in treatment delay. There may also be differences in treatment-related survivorship quality of life; approximately 54 % of the women in this sample treated with mastectomies received breast reconstruction surgery. Despite the high reconstruction rates, most women did not receive definitive completion. African American women have higher reconstruction complication rates than Caucasian women; these data provide additional evidence to suggest a disparity in breast reconstruction outcomes by race.     

Geographic clustering of adequate diagnostic follow-up after abnormal screening results for breast cancer among low-income women in Missouri

PURPOSE: In an effort to examine a cluster of late-stage breast cancer, this study reports (1) the extent of geographic variation in adequacy of diagnostic follow-up (ADFU) after abnormal breast cancer screening results across Missouri's counties and census tracts, (2) whether various personal characteristics or area poverty account for any geographic clustering observed, and (3) the association between area poverty rate and ADFU. METHODS: We used 1998-2002 Missouri Show Me Healthy Women breast and cervical cancer program data from 2580 low-income women aged 50-64 who had abnormal breast cancer screening results. ADFU was based on established guidelines. Poverty rate was from the 2000 census data. We used 3 complementary statistical approaches. RESULTS: Overall, 26.9% of screening results were inadequately followed up. County-level geographic variation accounted for 6.7% of the total variance in ADFU, while the census-tract-level variation was negligible. Women's sociodemographic characteristics, symptoms reported at time of screening, and screening results accounted for 25% of the county-level variation in ADFU. Statistically significant geographic variation in ADFU remained that could not be explained. Beyond 70 miles from the women's residence, the likelihood of receiving ADFU was geographically uncorrelated. We identified one large geographic cluster extending beyond the borders of counties and census tracts where women were less likely to receive ADFU (relative risk = 0.64; p = 0.01). CONCLUSIONS: Efforts to improve the likelihood of ADFU should be directed at examining the relative contributions of the healthcare and social environments and characteristics of the women in the area where women were less likely to receive ADFU especially in the cluster area of late-stage breast cancer rather than targeting efforts at the county or census-tract level.     

The Role of Poverty Rate and Racial Distribution in the Geographic Clustering of Breast Cancer Survival Among Older Women: A Geographic and Multilevel Analysis

The authors examined disparities in survival among women aged66 years or older in association with census-tract-level povertyrate, racial distribution, and individual-level factors, includingpatient-, treatment-, and tumor-related factors, utilizationof medical care, and mammography use. They used linked datafrom the 1992–1999 Surveillance, Epidemiology, and EndResults (SEER) programs, 1991–1999 Medicare claims, andthe 1990 US Census. A geographic information system and advancedstatistics identified areas of increased or reduced breast cancersurvival and possible reasons for geographic variation in survivalin 2 of the 5 SEER areas studied. In the Detroit, Michigan,area, one geographic cluster of shorter-than-expected breastcancer survival was identified (hazard ratio (HR) = 1.60). Anadditional area where survival was longer than expected approachedstatistical significance (HR = 0.4; P = 0.056). In the Atlanta,Georgia, area, one cluster of shorter- (HR = 1.81) and one clusterof longer-than-expected (HR = 0.72) breast cancer survival wereidentified. Stage at diagnosis and census-tract poverty (andpatient's race in Atlanta) explained the geographic variationin breast cancer survival. No geographic clusters were identifiedin the 3 other SEER programs. Interventions to reduce late-stagebreast cancer, focusing on areas of high poverty and targetingAfrican Americans, may reduce disparities in breast cancer survivalin the Detroit and Atlanta areas. breast neoplasms; cluster analysis; geography; population groups; poverty; survival     

Loss-framed minimal intervention increases mammography use

INTRODUCTION: Although mammography is the most effective early detection breast cancer screening technology available, it is underutilized. This study was conducted to test the effectiveness of a loss-framed minimal intervention to increase mammography use. Loss-frame refers to a communication strategy in which messages are framed from the perspective of what a person has to lose by not taking a particular behavioral action. METHODS: Participants were medically un- and underinsured women 50-64 years old who called one of two urban clinics randomly selected based on demographic statistical equivalency. The women who participated telephoned to inquire about a mammogram during the 6-month study period. The group randomly designated as the experimental group received a loss-framed message conveyed by trained staff telephonically. Members of the comparison group received the "usual" communication, also conveyed telephonically. In the experimental group, 31 of 112 (27%) women who inquired received mammograms, whereas 157 of the 992 (16%) comparison group women who inquired received mammograms. RESULTS: The odds of a mammogram, adjusted for race and breast cancer symptoms, significantly increased for the experimental (odds ratio [OR] = 1.914, chi2 = 7.48, p = .0063, 95% confidence interval [CI] 1.20-3.05) versus comparison group. CONCLUSIONS: A loss-framed, in-reach, minimal intervention approach holds promise as a mammography promotion strategy.     

Validation of recall of breast and cervical cancer screening by women in an ethnically diverse population

BACKGROUND: Screening mammogram and Pap smear rates are lower for women in underserved racial and ethnic groups, yet may be overestimated due to reliance on patients' self-reports. The purpose of this study was to determine accuracy of self-reports of mammograms and Pap smears in a multiethnic, multilingual population of African American, Latina, Chinese, Filipina, and White women residing in low-income census tracts of Alameda County, California. METHODS: Following a baseline telephone survey of 1,464 women regarding receipt of mammograms and Pap smears, we examined computerized and written medical records to validate the dates and locations of tests reported by women. RESULTS: Of 1,464 subjects, 94.9% reported having had a Pap smear, and 87% reported having had a mammogram. For Pap smears, in a subsample of 448 cases, we validated only 69.4% of the women's self-reports, and for mammography, in a subsample of 846 women, we validated only 75.4% of the self-reports. Validation rates differed significantly by ethnicity and site of care for both Pap smears and mammograms. CONCLUSIONS: Population estimates of breast and cervical cancer screening rates based upon patient self-reports need to be adjusted downward, by as much as one-quarter to one-third, for low-income, ethnic women.     

Community-based breast cancer intervention program for older African American women in beauty salons.

African American women are at high risk for morbidity and mortality from breast cancer. African American women ages 50 and older have been a difficult group to reach through conventional breast cancer intervention programs. Cultural and health beliefs that differ from mainstream society are reported to be factors contributing to the low rates of breast screening among this group. In addition to these attitudinal factors, older African American women are disproportionately represented among uninsured and under-insured Americans. As a result, cost becomes a barrier to mammography screening for many of these women. This project proposes to increase breast cancer screening awareness and provide a referral or free breast screening, or both, for African American women ages 50 and older. This information will be offered in the culturally familiar setting of local beauty salons. The culturally sensitive educational pamphlets developed by the National Cancer Institute (NCI) and video developed by the NCI-funded project, Cancer Prevention Research Unit, will be used to promote mammography, clinical breast examinations, and breast self-examination. Providers staffing a mobile mammography van provided by Dr. Anitha Mitchell of the Association of Black Women Physicians through a grant from the Breast and Cervical Cancer Control Program, funded by the Centers for Disease Control and Prevention, will perform mammograms for women on site during scheduled intervals. A followup telephone survey will be conducted.     

Use of computer kiosks for breast cancer education in five community settings.

Finding ways to bring effective computer-based behavioral interventions to those with limited access to technology is a continuing challenge for health educators. Computer kiosks placed in community settings may help reach such populations. The Reflections of You kiosk generates individually tailored magazines on breast cancer and mammography and was adapted from an evidence-based intervention that increased mammography use in African American women. This usage study tracked patterns of use and characteristics of kiosk users in beauty salons, churches, neighborhood health centers, Laundromats, and social service agencies in St. Louis. Kiosks were used 4,527 times in 470 kiosk days at 40 different host sites. Highly significant differences among community settings were found in rates and patterns of kiosk use as well as user characteristics, breast cancer knowledge, and use of mammography. Findings inform strategic decision making about technology dissemination and community outreach to women needing information about breast cancer and mammography.     

Correlates of consistent condom use among HIV-positive African American women.

INTRODUCTION: African American women are the fastest growing group at risk of contracting HIV, as over 68% of women diagnosed with HIV are African American. The present study used social-cognitive theory and the theory of gender and power to identify correlates of consistent condom use among African American women living with HIV. METHODS: We recruited 366 women, 18-50 years of age and living with HIV from several HIV/AIDS clinics in the southeastern United States. The majority of women, 84.2% (N = 308), were African American. Women completed a baseline interview assessing sociodemographic, psychosocial, and partner-related factors potentially associated with consistent condom use, defined as reported use of condoms during every vaginal sex episode with a male sexual partner in the past 30 days. RESULTS: Among those HIV-positive African American women reporting use of a condom in the past 30 days (n = 234, 70%), consistent condom use was reported by 67.1% of women. This rate was lower (51.6%) among women having an HIV-positive male sexual partner; the rate was higher (74.1%) among women having an HIV-negative male sexual partner. Compared to women who were inconsistent condom users, women with HIV were more likely to use condoms if they: had high partner communication self-efficacy (OR = 7.77, 95% CI = 3.3-18.6, p = .001), had a HIV-negative male sex partner (OR = 4.62, 95% CI = 1.9-11.5, p = 0.001), had low partner-related barriers to condom use (OR = 4.68, 95% CI = 1.8-12.2, p = 0.001), and had perceived peer norms supportive of condom use (OR = 2.38, 95% CI = 1.0-5.7, p = 0.03). CONCLUSION: These findings suggest that HIV interventions may enhance consistent condom use among African American women living with HIV by targeting women's self-efficacy to communicate with their partners and women's perception of personal and partner-related barriers to condom use.     

Screening mammography in the American elderly

BACKGROUND: Substantial differences exist in estimates of the proportion of elderly women who undergo screening mammography and the impact of race and ethnicity on mammography usage. METHODS: A representative 5% sample of elderly women living in 11 Surveillance, Epidemiology, and End Results areas from 1991 to 2001 was constructed using Medicare data. Biennial rates of screening mammography (at least one mammogram within each 2-year period) were calculated for overlapping 2-year periods, adjusting to a 2000-2001 age and race distribution. Multivariate repeated-measures logistic regression was used to examine predictors of screening usage. RESULTS: The sample included 146,669 women. Between 1991 and 2001 the age- and race-adjusted proportion of women aged 65 years and older who underwent at least biennial screening mammography increased from 35.8% to 47.9%. Mammography screening increased for all racial and ethnic groups, but remained significantly higher for non-Hispanic white women as compared with all other groups. The biennial screening rate in 2000-2001 was 50.6% for non-Hispanic white, 40.5% for African-American, 34.7% for Asian-American, 36.3% for Hispanic, and 12.5% for Native-American women. After controlling for age, site, physician access, comorbidities, education, and income, African Americans (odds ratio [OR] = 0.80, 95% confidence interval [CI] = 0.78-0.83), Asian Americans (OR=0.53, CI = 0.51-0.55), Hispanics (OR = 0.70, CI = 0.67-0.74), and Native Americans (OR=0.37, CI=0.29-0.46) were still all less likely than non-Hispanic white women to undergo screening. CONCLUSIONS: Elderly women undergo significantly less mammography screening than is suggested by self-reported surveys. All groups of non-white women undergo less screening than do white women. The magnitude of the difference in screening rates comparing Asian-American and Hispanic women with white women is especially large; however, other studies have questioned the sensitivity of Medicare data for identifying people of Asian and Hispanic ethnicity. For African-American women, the magnitude of the gap is smaller, but it is of concern that the gap in screening as compared with white women has grown over time.     

The effect of Medicare reimbursement for screening mammography on utilization and payment. National Cancer Institute Breast Cancer Screening Consortium.

OBJECTIVE: In January 1991, Medicare extended its mammography benefit to reimburse for breast cancer screening mammograms. In 1991 and again in 1993, the National Cancer Institute Breast Cancer Screening Consortium (BCSC) conducted a survey to test the hypothesis that this benefit would increase mammography use among women over the age of 65. METHODS: The authors analyzed data on non-Hispanic white women ages 65 to 74 living in 11 geographic areas targeted by the BCSC for an earlier study--six that had received cancer screening educational interventions and five control subsites--to measure the impact of the newly adopted Medicare benefit on the use of mammography and use of Medicare to reimburse mammography costs. RESULTS: The data show little overall increase between 1991 and 1993 in reported mammography use among respondents to the survey. However, in six intervention and five control subsites there was an increase in the percentage of women who reported using public payment sources to at least partially reimburse the cost of mammograms. In three intervention subsites, the increase from 1991 to 1993 in the percentage of women using public sources of payment was greater than in the corresponding control subsites. CONCLUSIONS: These findings suggest that public health interventions are more likely to succeed when educational promotion accompanies a financial benefit.
