Predictors of Breast Cancer Screening in a Panel Study of African American Women

ABSTRACT

Purpose: This study examines the predictors of breast cancer screening participation in a panel study of African American women over age 40. We examine the effect of depression, age, beliefs and concerns about breast cancer and its risk, communication with social networks regarding screening, marital status, participation in religious organizations, breast cancer family history, and participation in a breast cancer education program.

Methods: Participants were recruited from 30 African American churches, two low-income housing projects, and from a health fair at a historically African American University (N = 364). Participants were interviewed upon recruitment, and three months later. Multinomial logistic regression models are estimated to assess the relative impact of covariates on the odds of getting a mammogram while controlling for other factors. We also assess predicted probabilities of screening at specific levels of covariates.

Results: We find that age, marriage, an educational intervention, talking with friends, and believing that early detection can lead to cure had a positive impact on getting a mammogram between T1 and T2. In contrast, depression significantly reduces the odds of getting a mammogram. Family histories of breast cancer and church participation have no effect on rates of mammography net of other factors.     

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.     

Breast cancer screening among African American women: adherence to current recommendations

Breast cancer remains one of the leading causes of cancer death among African American women, and rates of mammography screening for African American women remain lower than rates for their Caucasian counterparts. The purpose of the current study was to explore the reasons for nonadherence to American Cancer Society breast screening guidelines among African American women who had not received a mammogram within the past year. Participants included 91 African American women between 40 and 84 years of age recruited from churches, housing projects, and a health fair at a historically African American university who had not received a mammogram within the past 12 months. Findings revealed that 36% of participants had never received a mammogram, 43% did not have their breasts examined by their doctor once a year, 55% did not perform monthly self-examination, and 23% did not know how to examine their breasts for breast cancer. The most frequently reported reason for not getting a mammogram was because the participant's doctor had not suggested it.     

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

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

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.     

Women's Behaviors Toward Mammogram and Pap Test: Opportunities to Increase Cervical Cancer Screening Participation Rates among Older Women

Objectives

Screening rates for cervical cancer remain moderate among women over 50 years of age. Because cervical and breast screening interventions can be linked, evaluating screening factors relating to both is important. This study evaluates factors associated with breast and cervical screening participation in women aged 52 to 69.

The contribution of emotional characteristics to breast cancer screening among women from six ethnic groups

BACKGROUND: This study was designed to determine which of several emotional propensities were associated with the frequency of mammograms and clinical breast exams among six groups of minority women. Three emotion-related variables that have been identified in the previous literature as influencing screening were examined: Repression, cancer worry, and embarrassment. However, these variables have never been examined within the same study, nor where relevant background variables are controlled. METHODS: 1364 African American, US-born white, English-speaking Caribbean, Haitian, Dominican, and Eastern European women were recruited via stratified-cluster sampling. Participants provided demographics and measures of beliefs and knowledge. RESULTS: As expected, self-regulation and cancer worry were both positively associated with mammogram and clinical breast exam frequency, while embarrassment regarding having a mammogram was negatively associated with screening. These results held even after controlling for demographic variables and the presence or absence of physician recommendation. Screening rates for African American women equaled or exceeded the rates for European Americans. Other minority subpopulations had even lower screening rates, including women from the English-speaking Caribbean and Haitians. CONCLUSIONS: Results are discussed in terms of their implications for screening intervention, models of health behavior, and the need for more precise operationalizations of ethnicity in screening research.     

Peer Reviewed: Differences in Knowledge of Breast Cancer Screening Among African American,Arab American,and Latina Women

Introduction

We examined differences in knowledge and socioeconomic factors associated with 3 types of breast cancer screening (breast self-examination, clinical breast examination, and mammogram) among African American, Arab, and Latina women.

Methods

Community health workers used a community-based intervention to recruit 341 women (112 Arab, 113 Latina, and 116 African American) in southeastern Michigan to participate in a breast cancer prevention intervention from August through October 2006. Before and after the intervention, women responded to a previously validated 5-item multiple-choice test on breast cancer screening (possible score range: 0 to 5) in their language of preference (English, Spanish, or Arabic). We used generalized estimating equations to analyze data and to account for family-level and individual correlations.

Results

Although African American women knew more about breast cancer screening at the baseline (pretest median scores were 4 for African American, 3 for Arab and 3 for Latina women), all groups significantly increased their knowledge after participating in the breast cancer prevention intervention (posttest median scores were 5 for African American and 4 for Arab and Latina women). Generalized estimating equations models show that Arab and Latina women made the most significant gains in posttest scores (P < .001).

Conclusion

Racial/ethnic differences in knowledge of breast cancer screening highlight the need for tailored information on breast cancer screening for African American, Arab, and Latina women to promote adherence to breast cancer screening guidelines.     

Correlates of breast cancer screening among low-income, low-education Latinas.

INTRODUCTION: This paper discusses the factors associated with breast cancer screening among low-education, low-income Latinas. BACKGROUND: These data were collected as part of a breast cancer educational intervention study aimed at this population. The objective of the larger study was to evaluate multimedia methods as an appropriate medium for educating this population of Latinas about breast cancer. METHODS: The study was designed as a field experiment with a pre and posttest design. A total of 1,197 individuals participated in the study, and these were all self-identified Latinas above the age of 40 years who fit the screening criteria of low income and education levels. Of these, 583 individuals provided the baseline (pretest) data on mammogram attitudes, knowledge, and intentions analyzed in this paper. RESULTS: Our results indicate that breast cancer screening knowledge and having a regular doctor were significant factors in ever having had a mammogram and having had a recent mammogram in this sample of low-income, low-education Latinas. Age affected the odds of ever having had a mammogram, but not a recent mammogram. CONCLUSION: Attitudes toward mammography, insurance status, and demographic factors such as foreign birth were not significant predictors of mammography screening in this study.     

Caregiving associated with selected cancer risk behaviors and screening utilization among women: cross-sectional results of the 2009 BRFSS

ABSTRACT: BACKGROUND: Informal caregiving is increasingly common as the U.S. population ages, and there is concern that caregivers are less likely than non-caregivers to practice health-promoting behaviors, including cancer screening. We examined caregiving effects on cancer risk behaviors and breast and cervical cancer screening in the 2009 Behavioral Risk Factor Surveillance System. METHODS: Women age [GREATER-THAN OR EQUAL TO]41 with data on breast and cervical cancer screening were included (weighted frequency 3,478,000 women). Cancer screening was classified according to American Cancer Society guidelines. We evaluated the association of caregiving with cancer risk behaviors (obesity, physical activity, alcohol intake, smoking status, and fruit/vegetable consumption) and cancer screening (mammography, clinical breast exam [CBE], and Pap test) using logistic regression overall and with stratification on age (<65, [GREATER-THAN OR EQUAL TO]65) or race (white, non-white). RESULTS: Caregivers had greater odds of being obese, physically active, and current smokers. Subgroup analyses revealed that caregiving was associated with obesity in younger women and whites, and with less obesity in older women. Also, caregiving was associated with smoking only among younger women and non-whites. Caregivers had greater odds of ever having had a mammogram or CBE, yet there was no association with mammogram, CBE, or Pap test within guidelines. CONCLUSIONS: Caregiving was associated with some health behaviors that increase cancer risk, yet not with cancer screening within guidelines. Effects of caregiving by age and race require confirmation by additional studies.     

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.     

Communicating breast cancer risk: patient perceptions of provider discussions

This study investigated the relationship between breast cancer risk communication delivered by providers and patient knowledge, perceptions, and screening practices. Telephone interviews were conducted with 141 African American (n = 71) and white (n = 70) first-degree relatives of breast cancer patients who received medical services at 2 university medical centers in North Carolina during 1994-95. Multiple items assessed subjects' reports of discussions with providers about family history and personal risk, knowledge of breast cancer risk factors, risk perceptions, breast cancer concerns, and screening practices. African American (AA) women were less likely than white women to report being informed of their increased personal risk of breast cancer because of family history. After controlling for education level, AA women aged > or = 50 years were less likely than white women to have ever had a mammogram. Both AA and white women who discussed family history and risk with their providers were significantly more likely to have had a mammogram within the past 2 years. Although these discussions seemed to increase participants' perceived risk of developing breast cancer, they did not promote knowledge of risk factors or increase levels of cancer concern. Study results indicate that provider discussions about family history and personal risk, accompanied by increases in risk perception, promote patient compliance with screening goals. Findings suggest that accurate knowledge about specific breast cancer risk factors may not be necessary to achieve screening compliance. However, additional studies are needed to investigate the relationship between knowledge of breast cancer risk factors and the adoption of behaviors associated with reducing breast cancer risk.     

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.     

Breast cancer risk perception, benefits of and barriers to mammography adherence among a group of Iranian women

The study aimed to assess associations between Health Belief Model variables, stages of change, and participation in mammography for early detection of breast cancer in a sample of Iranian women. A total of 414 women, aged 40 to 73 years, were recruited by random sampling. The study took place in the winter of 2007, using a self-report questionnaire and structured interviews, designed to measure the five Health Belief Model constructs and stages of adoption for mammography. The study indicated that 45.8% of the women were in the pre-contemplation and contemplation stages of a mammogram, and 29% of participants reported having had at least one mammogram. Screening behavior was associated with older age, familial history of breast cancer, history of breast disease, health insurance coverage, and living in an urban area. Furthermore, the perceived susceptibility to breast cancer, perceived benefits and barriers for mammography, and cues to action variables defined by the Health Belief Model were four factors related to having a mammogram. The study concludes that health care professionals must provide women with more fear appeals that outline vulnerability to developing breast cancer, remove cognitive barriers to seeking mammography, and apply effective guidance on the participation of women in breast cancer screening programs.

Receipt of cancer screening services: surprising results for some rural minorities

Background: Evidence suggests that rural minority populations experience disparities in cancer screening, treatment, and outcomes. It is unknown how race/ethnicity and rurality intersect in these disparities. The purpose of this analysis is to examine the cancer screening rates among minorities in rural areas. Methods: We utilized the 2008 Behavioral Risk Factor Surveillance System (BRFSS) to examine rates of screening for breast, cervical, and colorectal cancer. Bivariate analysis estimated screening rates by rurality and sociodemographics. Multivariate analysis estimated the factors that contributed to the odds of screening. Results: Rural residents were less likely to obtain screenings than urban residents. African Americans were more likely to be screened than whites or Hispanics. Race/ethnicity and rurality interacted, showing that African American women continued to be more likely than whites to be screened for breast or cervical cancer, but the odds decreased with rurality. Conclusions: This analysis confirmed previous research which found that rural residents were less likely to obtain cancer screenings than other residents. We further found that the pattern of disparity differed according to race/ethnicity, with African Americans having favorable odds of receipt of service regardless of rurality. These results have the potential to create better targeted interventions to those groups that continue to be underserved.     

Promotion of breast cancer screening in a work site population

We investigated whether attitudes, intentions, and practices regarding breast cancer screening by mammography and clinical breast examination could be positively influenced through a brief educational intervention administered to women employees at diverse work sites. The educational intervention involved the mailing of American Cancer Society brochures that discussed breast cancer screening and contained guidelines on the recommended frequency for each screening modality according to age. Effects of the intervention were measured through pre/post questionnaires. The results were positive for the entire group of women who participated, as evidenced by their increased perception of the importance of mammography and clinical breast examination and of the priority of getting a mammogram regularly, their decreased perception of mammography as an uncomfortable procedure, and the increased frequency of discussions of breast cancer screening at work. Employers, particularly large corporations and agencies, must realize that by introducing effective work site cancer screening programs they not only fulfill their social responsibility to contribute to their employees’ health, but also achieve reductions in health care costs.     

Participation in annual skin cancer screening among women seeking routine mammography

BACKGROUND: Early detection of skin cancer is associated with improved prognosis. The American Cancer Society's current skin cancer screening (SCS) recommendation states that adults over the age of 40 should receive an annual skin examination conducted by a health professional. However, little is known about the psychosocial factors related to participation in annual SCS, which remains relatively low among the general public. METHODS: Data were collected from women, aged 50 and older, seeking routine mammography at a large, urban, breast diagnostic facility. RESULTS: A total of 253 eligible women completed the survey. Overall, 20.2% of women reported receiving annual clinical SCS. Physician recommendation, self-efficacy, perceived susceptibility, and age were significantly associated with participation in annual skin screening. CONCLUSIONS: Similar to previously reported findings in the literature, our rates of participation in annual clinical skin screening were lower than reported rates for other types of cancer screening. Among older women, multiple covariates for participation in annual skin cancer screening were determined and may serve to guide future health education interventions to promote screening. Our findings suggest that participation could improve through increasing physician recommendation, screening self-efficacy, and individuals' sense of perceived susceptibility to skin cancer.     

Self‐Reported Cancer Screening Among Elderly Medicare Beneficiaries: A Rural‐Urban Comparison

Purpose: We examined the rural‐urban disparity of screening for breast cancer and colorectal cancer (CRC) among the elder Medicare beneficiaries and assessed rurality's independent impact on receipt of screening. Methods: Using 2005 Medicare Current Beneficiary Survey, we applied weighted logistic regression to estimate the overall rural‐urban disparity and rurality's independent impact on cancer screening, controlling for patient, and area factors. Results: From urban, large rural, small rural, and isolated rural areas, the rates for mammogram last year were 53%, 52%, 45%, and 44%, respectively. They were 56%, 50%, 48%, and 43% for CRC screening, respectively. After controlling for patient and area level characteristics, rurality is significantly associated with CRC screening, but not mammogram. Conclusions: We found rural‐urban disparities for both mammogram and CRC screenings. Patient and area factors totally eliminated the rural‐urban disparity for mammogram but not CRC screening. Health promotions to improve cancer screening should focus more on small and isolated rural areas.
