An intervention study on screening for breast cancer among single African-American women aged 65 and older

BACKGROUND: Older African-American women with single marital status are least likely to use screening procedures. This study aimed to evaluate a breast screening intervention program conducted in this population. METHODS: Ten public housing complexes were randomly assigned to either the intervention or the control group. African-American women aged 65 and over were recruited into the study if they were widowed, divorced, separated, or never married and did not have a history of breast cancer (n = 325). The intervention program was delivered by lay health educators at the participant's apartment and was designed to increase knowledge about breast screening, reduce psychological problems, and increase support from significant others. Breast-screening-related cognition and behavior were measured at baseline and at 1 and 2 years postintervention. RESULTS: Comparisons of the preintervention and postintervention measurements showed that while the proportion of women who had a clinical breast examination or mammogram in the preceding year was decreased at 1 year postintervention in the control group, it was increased in the intervention group. However, the differences did not reach a significant level. No consistent patterns could be found in changes of breast self-examination and variables in knowledge, attitudes, and beliefs. When analyses were restricted to women whose significant others had provided information or help on breast screening, results were better, but the differences between the intervention and control groups still did not reach statistical significance. CONCLUSIONS: These results did not suggest significant effects of an intervention program that used lay health educators to promote breast cancer screening in older single African-American women.     

Breast cancer screening in older African-American women: qualitative research findings

PURPOSE. The purpose of this study was to gain a better understanding of the cultural meanings that shape the breast cancer screening behavior of older African-American women. DESIGN. Qualitative research methods elicited social and cultural themes related to breast cancer screening. SETTING. Focus group interviews were conducted in the natural settings (churches, etc.) of older African-American women. SUBJECTS. Interviews were conducted with 132 members from 14 social networks of older African-American women. MEASURES. A focus group guide asked about 1) perceived risk of breast cancer, 2) behavioral intentions about breast cancer screening, 3) health seeking behavior, and 4) social support. RESULTS. For older African-American women: other health concerns are of more concern than breast cancer; age is generally not recognized as a risk factor for breast cancer; fear of finding breast cancer and its social consequences are salient barriers to mammography; they tend to rely on breast self-exam rather than mammography to detect a breast problem; cost may be more an issue of competing priorities than cost per se; the tradition is to go to doctors for a problem, not prevention; and women in their own social networks are important sources of social support for health concerns. CONCLUSIONS. These data offer explanations for mammography screening in older African-American women and emphasize the strength of naturally existing sources of social support for designing interventions to increase breast cancer screening.     

Correlates of cervical cancer screening among underserved Hispanic and African-American women

BACKGROUND: Substantial subgroups of American women, specifically those of ethnic minorities, have not been screened for cervical cancer or are not screened at regular intervals. The rates for receipt of female-related cancer screening tests remain far below the goals set forth in Healthy People 2010. OBJECTIVE: This study applied a well-known, recently revised theoretical model of health care access and utilization, the Behavioral Model for Vulnerable Populations, to examine the correlates of the adherence to cervical cancer screening guidelines among publicly housed Hispanic and African-American women, two of the most vulnerable segments of our population. METHODS: This study conducted a cross-sectional survey of a community-based random sample of 230 African-American and Latino female heads of household, from a geographically defined area, the three urban public housing communities in Los Angeles County, CA. RESULTS: Only 62% of our sample had received a screening for cervical cancer within the past year. Yet, 29% of the sample claimed that no health care provider had ever told them that they needed a screening test for cervical cancer. Hispanic and older women are by far less likely to adhere to screening guidelines; in this study, 51% of Hispanics and 22% of African-Americans reported no screening within the last year. Multivariate analysis shows that affordability, continuity of care, and receiving advice from health care providers regarding a Papanicolaou (Pap) smear were significant predictors of up-to-date to cervical cancer screening. CONCLUSION: This study documents a significant disparity in screening for cervical cancer among underserved minorities, particularly Hispanic, uninsured, and older women. The continuity of obtaining medical services and receiving recommendations from physicians remain the core factors that are significantly associated with obtaining cervical cancer screening. These results underscore the need for continued efforts to ensure that medically underserved minority women have access to cancer screening services.     

Psychosocial correlates of cervical cancer screening among older Hispanic women

Early detection through screening can reduce mortality rates of cervical cancer, and yet Hispanic women who have incidence rates higher than their non-Hispanic White counterparts are least likely to participate in cancer screening initiatives. This study utilized data from the 2008 wave of the Health and Retirement Study to investigate the psychosocial correlates associated with older Hispanic women’s participation in cervical cancer screening services. Logistic regression models were used. Findings indicated that greater life satisfaction and religiosity were associated with a greater likelihood of participating in cervical cancer screening. Despite ongoing national conversations, evidence indicates there is agreement that underserved women need to be screened, particularly the older Hispanic population.     

Understanding the barriers to cervical cancer screening among older women

Despite the fact that 90% of cervical cancers can be prevented by regular Pap screening, many women are not screened regularly, particularly older women. To understand better the barriers to screening, the authors held five focus groups during April 2000 in Prince Edward Island (PEI), Canada. Of the 32% of women aged 45 to 70 who had not been screened over a 5-year period (1995-2000), 60 randomly selected women participated in this research. The authors analyzed discussions for themes using an inductive approach, with interpretation guided by the population health model. Women who have avoided a Pap test are falling between the cracks created by a complex interaction between personal experiences and the health system's approach to Pap screening.     

Cervical human papillomavirus screening among older women

Rates of acquisition and clearance of cervical human papillomavirus (HPV) during a 3-year period in women 51 years of age were compared with rates in younger women to provide data on cervical screening for women >50 years of age. Paired, cytologically negative, archived cervical smears taken 3 years apart from 710 women in Nottingham, United Kingdom, were retrieved and tested for HPV infection with polymerase chain reaction (PCR) with GP5+/6+ primers. Seventy-one (21.3%) of 333 women 51 years of age who were HPV negative at baseline were positive 3 years later. This percentage was higher than the corresponding acquisition rates among women 21 (15.2%), 31 (14.1%), and 41 (13.3%) years of age, although these differences were not significant. This retrospective study shows that HPV-negative women >50 years of age can acquire HPV and, therefore, require cervical screening.     

Mammography use among older Mexican-American women: correcting for over-reports of breast cancer screening

OBJECTIVES: To determine the accuracy of self-reported mammography use and generate a correction factor that adjusts for reporting errors among Mexican-American women. DESIGN: Self-reported mammography use was compared with a medical chart review. PARTICIPANTS: A random sample of 199 Mexican-American women aged 50-74 in southeast Texas. MAIN OUTCOME MEASURES: Self-reported mammography use for the preceding 2 years and mammography use determined by medical chart review. RESULTS: Positive and negative predictive values of mammography self-reports in the previous 2 years were 73.9 and 86.0%, respectively. The correction factor was 79.6%, or approximately 80% of the self-reported mammograms within the preceding 2 years could be verified through medical chart reviews. CONCLUSIONS: Mammography use rates among Mexican-American women were not as high as self-reports indicated. Estimates need to be adjusted downward by approximately 20%.     

Cultural and emotional determinants of cervical cancer screening among older Hispanic women

Older adults are at highest risk of cancer and yet have the lowest rates of cancer screening participation. Older minority adults bear the burden of cancer screening disparities leading to late stage cancer diagnoses. This investigation, utilization data from the 2008 wave of the Health and Retirement study examined the cultural and emotional factors thought to influence cervical cancer screening among older Hispanic women. We utilized logistic regression models to conduct the analyses. Findings indicate that the emotional factors were not significant but the cultural factor, time orientation was a significant predictor for older Hispanics' cervical cancer screening behaviors.     

Colorectal cancer screening among African-American and white male veterans

BACKGROUND: Population-based studies from Medicare and privately insured individuals have consistently identified lower rates of colorectal cancer-screening tests among African-American versus white individuals. The purpose of this study was to evaluate whether, at a Veterans Affairs (VA) medical center, similar racial/ethnic differences in colorectal cancer screening could be identified. METHODS: Study participants were male veterans, aged > or =50, attending a general medicine clinic in a VA hospital, who had not had either a fecal occult blood test (FOBT) within the past year or a flexible sigmoidoscopy/colonoscopy within the past 5 years. Based on review of electronic medical records, rates of physician recommendation for FOBT, flexible sigmoidoscopy, or colonoscopy, and patient completion of these tests were obtained and compared by race/ethnicity. RESULTS: Sixty percent of 1599 veterans had not undergone recent colorectal cancer screening. Physicians recommended colorectal screening tests equally among African-American and white patients (71.0% vs 68.2%, p=0.44). African-American patients were 1.3 times more likely than white patients to receive colorectal screening procedures (36.3% vs 28.9%, p=0.03). CONCLUSIONS: In contrast to other settings, in a general medicine clinic at a VA hospital, rates of colorectal cancer-screening tests were not lower for African-American patients compared to white patients.     

Colorectal cancer screening participation by older women

OBJECTIVE: Although recent screening guidelines recommend annual fecal occult blood testing (FOBT) for adults aged > or = 50, a number of studies report that these tests are underused. Systematic efforts to increase awareness of colorectal cancer (CRC) and to promote screening participation are needed to meet national objectives for CRC control. METHODS: This study examined CRC-screening practices and evaluated factors related to recent participation in screening by FOBT in a sample of women aged 50 to 80 who were surveyed about their use of clinical preventive services at Group Health Cooperative, a managed care organization in western Washington State. RESULTS: Of the 931 women eligible for analysis, 75% reported ever having been screened by FOBT and 48% reported having been screened within 2 years before the survey. Participation in screening did not vary by demographic characteristics or by perceived or actual risk of CRC. Women with a positive attitudes toward CRC screening had sevenfold greater odds of recent screening by FOBT (odds ratio=7.1; 95% confidence interval, 4.4 to 11.6). Only 58% of study women reported that their physicians encouraged CRC screening, but this factor was strongly related to participation (odds ratio=12.7; 95% confidence interval, 6.6 to 24.4). CONCLUSIONS: We identified several areas in which understanding of CRC risk may be low. As a whole, these findings suggest that effective strategies to control CRC may include efforts to improve knowledge of risk and prevention, but must also appeal directly to primary care physicians to identify and address their barriers to screening recommendations.     

Cervical cancer screening among Lebanese women

Background

Cervical cancer is a very common malignancy amongst women worldwide. Pap smear is an effective and inexpensive screening test in asymptomatic women. The aim of this paper was to assess the prevalence of Pap smear screening for cervical cancer among Lebanese women and to determine associated sociodemographic and psychosocial characteristics.

An intervention study on screening for breast cancer among single african-american women aged 65 and older

PURPOSE: Older single African-American women are the population that is least likely to use screening procedures because of cognition-related, income-related, social-support-related and medical care-related barriers. This study aims to evaluate a breast screening intervention program developed according to socioeconomic, cultural, psychological and behavioral characteristics of older single African-American women.METHODS: Ten public housing complexes were randomly assigned to either intervention or control group. African-American women aged 65 and over were recruited into the study if they were widowed, divorced, separated or never-married in the preceding year, and did not have a history of breast cancer (n = 325). Delivered by lay health educators, the intervention program targeted increasing knowledge on breast health and breast screening, reducing emotional or psychological problems, and increasing support from the significant others of study women. Breast screening-related cognition and behavior were measured at pre-intervention and post-intervention.RESULTS: Comparisons of the pre-intervention and post-intervention measurements showed that while the proportion of women who had a clinical breast examination or mammogram in the preceding year was decreased at the post-intervention in the control group, it was increased in the intervention group. However, the differences did not reach a significant level. No consistent patterns could be found in changes of variables in knowledge, attitudes and beliefs. These results remained similar when potential confounding factors were adjusted using mixed model regression analyses.CONCLUSIONS: These results did not suggest significant effects of an intervention program which used lay health educators to promote breast cancer screening in older single African-American women.     

BMI and cervical cancer screening among white, African-American, and Hispanic women in the United States

OBJECTIVES: We examined cervical cancer screening by BMI in white, African-American, and Hispanic women and explored women's reasons for not undergoing screening. RESEARCH METHODS AND PROCEDURES: We used logistic regression to examine Pap testing in the preceding 3 years across BMI groups for white (n = 6419), African-American (n = 1715), and Hispanic women (n = 1859) age 18 to 75 years who responded to the 2000 National Health Interview Survey. We used bivariable analyses to describe women's reasons for not undergoing testing and examined whether unscreened women received physician recommendations for screening. RESULTS: Of 12,170 women, 50% were normal weight, 26% were overweight, and 21% were obese. The proportion who reported Pap testing in the last 3 years was 86% in whites, 88% in African Americans, and 78% in Hispanics. After adjustment for sociodemographics, health care access, and illness burden, severely obese white women (BMI = 40+ kg/m2) were significantly less likely to undergo Pap testing (relative risk, 0.92; 95% CI, 0.83 to 0.99) compared with normal weight women. BMI was not associated with screening in African Americans or Hispanics. A higher proportion of obese white women than normal weight women cited putting off the test or embarrassment or discomfort as the primary reason for not undergoing screening. Among the unscreened, obese women were as likely as normal weight women to receive a physician recommendation to undergo screening. DISCUSSION: Disparities in cervical cancer screening by body weight persist for white women with severe obesity. Disparities were not explained by differences in the rate of physician recommendations for screening, but obese white women may be more likely to delay screening or to find screening painful, uncomfortable, or embarrassing than normal weight white women. Efforts to increase screening among obese women should address women's reservations about screening.     

Worry regarding major diseases among older African-American,Native-American,and Caucasian women

This study examined worry regarding seven major diseases and their correlates in a sample of African-American (n = 57), Native-American (n = 50), and Caucasian (n = 53) women ages 36 to 91 years. African-American and Native-American women were most worried about developing cancer (44% and 50%, respectively) while Caucasian women were most worried about osteoporosis (37%) and cancer (33%). Women from each ethnic group were more worried about developing cancer than cardiovascular diseases and conditions. African-American and Native-American women were more worried than Caucasian women about developing diabetes and high cholesterol. Body mass index (BMI) was a consistent correlate of worry: heavier women were more worried about developing diseases than were leaner women. Other risk factors (e.g., physical activity, blood pressure), however, were generally not associated with disease worry. In fact, age was inversely associated with worry regarding diabetes, cancer, and osteoporosis. Although women who were more worried about developing cancer were more likely to perform monthly breast self-exams, worry regarding other diseases was not associated with preventive actions. These results are generally consistent with other studies that indicate women are more concerned about cancer than cardiovascular diseases.     

Comparative analysis of breast cancer risk factors among African-American women and White women

The authors assessed risk factor profiles among 1,505 African-American and 1,809 White women in the 1993-2001 Carolina Breast Cancer Study. Multiple logistic regression models for case-control data were used to estimate odds ratios for several factors. Racial differences were observed in the prevalence of many breast cancer risk factors among both younger (aged 20-49 years) and older (aged 50-74 years) women. For older women, the magnitude and direction of associations were generally similar for African-American and White women, but important racial differences were observed among younger women. In particular, multiparity was associated with increased risk of breast cancer among younger African-American women (for three or four pregnancies: adjusted odds ratio (OR) = 1.5, 95% confidence interval (CI): 0.9, 2.6; for five or more pregnancies: OR = 1.4, 95% CI: 0.6, 3.1) but not among younger White women (for three or four pregnancies: OR = 0.7, 95% CI: 0.4, 1.2; for five or more pregnancies: OR = 0.8, 95% CI: 0.2, 3.0). The relations with age at first full-term pregnancy and nulliparity also varied by race. Case-only analyses before and after further adjustment for tumor stage and hormone receptor status revealed little effect on results. Hence, racial variations in both prevalences of and risks associated with particular factors may contribute to the higher incidence of breast cancer among younger African-American women.     

Breast cancer screening among American Samoan women

BACKGROUND: Little is known about breast cancer screening practices or predictors of age-specific screening for Samoan women. METHODS: Through systematic, random sampling procedures, we identified and interviewed 720 adult (> or =30 years) Samoan women residing in American Samoa, Hawaii, and Los Angeles. Multivariate logistic regressions were performed to determine independent predictors for recent age-specific screening. RESULTS: Only 55.6% of women (> or =30 years) had ever had a CBE and 32.9% of women (> or =40 years) had ever had a mammogram. Furthermore, only 24.4 and 22.4% of Samoan women (> or =40 years) residing in Hawaii and Los Angeles, respectively, had an age-specific mammogram within the prior year. Independent predictors of age-specific CBE screening included age, education, health insurance, ambulatory visit, and being a resident of Hawaii or Los Angeles; those for mammography included ambulatory visit and awareness of screening guidelines. CONCLUSION: Population-based estimates of age-specific breast cancer screening among Samoan women are lower than the national objectives and those reported for other minorities. Targeted efforts that address doctor-patient communication on preventive behavior, improved access to health care services (especially in American Samoa), and focused educational awareness programs are needed to improve the dismal screening rates observed in this indigenous population.     

A community capacity-enhancement approach to breast and cervical cancer screening among older women of color

In the Screening Older Minority Women project, the authors applied a community capacity-enhancement approach to promoting breast and cervical cancer screening among older women of color. Members of informal support networks were recruited for this health promotion intervention to empower Latina and African American women to engage in positive health behaviors. The authors describe the phases of the intervention and the experiences from the community. Guidelines are identified to help researchers and practitioners in planning and implementing community health promotion intervention with women of color.
