Effect of media coverage and physician advice on utilization of breast cancer screening by women 40 years and older

The purpose of this study is to examine the relative importance of media coverage and physician advice on the decision of women 40 years and older to obtain a mammogram. Five theoretical models, by which media coverage and physician advice may interact to affect individual health behavior, are presented. These models are tested with time-series regression analysis based on national-level data on mammography utilization and physician advice from the Behavioral Risk Factor Surveillance System (BRFSS) and content analysis of mammography-related national news coverage. Results suggest that although physician advice plays a key role in women's decisions to have mammograms, media coverage of mammography screening also contributes to mammography utilization by women. In particular, media coverage seems to be important for women who do not have regular contact with a physician or access to physicians. A possible conclusion is that mass media and physician advice complement one another in persuading individuals to adopt preventive health behavior.

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.     

Management of operable breast cancer in older women

Older women are not being given the opportunity to benefit from the improvements in both local and systemic treatment for breast cancer. Mammographic screening call/recall system ceases at age 72, making access more difficult. Knowledge about breast cancer in those aged >75 is significantly reduced in terms of understanding symptoms and personal risk but studies have shown that intervention can improve this, at least in the short term. Although older women are more likely to have estrogen receptor positive tumours, nevertheless, more than one-third of women aged over 70 have grade III, aggressive breast cancers. Whenever possible, older women should be offered breast conserving therapy rather than mastectomy since this not only improves their quality of life but also reduces risk of subsequent mental health problems. Endocrine treatment alone should not be used other than in patients with severe co-morbidity and a life-expectancy of less than a year. As adjuvant treatment in those with estrogen receptor positive cancers, the choice between tamoxifen and an aromatase inhibitor will depend upon co-morbidity, side-effects and patient choice.     

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%.     

Breast cancer screening among relatives of women with breast cancer.

BACKGROUND. National surveys indicate that only 15% to 30% of all women in the general population 50 years of age or older have an annual mammogram. METHODS. We studied first-degree female relatives of women with breast cancer, who are at elevated risk of disease, to describe the breast cancer screening practices of these relatives and to improve their practices through a program of intensive education. We report here the screening behaviors of 2471 relatives of women with breast cancer. RESULTS. Self-reported behaviors were as follows: 49% performed monthly breast self-examination and 70% had annual breast examinations by a medical professional. Of 983 women 50 years of age or older, 49% had had a mammogram, but only 14% have a mammogram annually. Of women 50 years of age or older who had never had a mammogram, 92% reported never having had one recommended by a medical professional. CONCLUSIONS. Our findings indicate that screening behaviors in relatives of breast cancer patients are not substantially different from those of women in the general population. Enhanced efforts both to educate medical professionals and to encourage women to demand screening mammography are necessary to reduce breast cancer mortality.     

To screen or not to screen: the issue of breast cancer screening in older women

INTRODUCTION: The United States Preventive Services Task Force (USPSTF) recommends that women aged 50-69 receive timely breast cancer screening, but does not make a recommendation for women aged 70 and older. Our purpose is to assess the relationship between age and breast cancer screening trends, and to consider the issue of breast cancer screening of women 70 years of age and older in light of demographics, disease burden, life expectancy, and activity level. METHODS: Data were analyzed from the state-based Behvioral Risk Factor Surveillance System (BRFSS) and the National Health Interview Survey (NHIS) on breast cancer screening practices and activity limitation status of women 50 and older. RESULTS: The percentage of women who reported receiving mammography and clinical breast examination within two years was lower among older women compared with younger women, and the gap has widened over time. In 1991-92, 61.4% of women 50-69 received screening within two years, compared to 49.5% of women 70 and above, while in 1997-98, the percentages were 71.1 and 56.7, respectively. Among both age groups and in both time periods, those unable to perform a major activity of daily living were less likely to report receiving mammography within two years than those with no limitation, and the gap was much wider in the elderly. Most (62.7%) women 70 and older reported having no activity limitation; only 5.5% reported being unable to perform a major activity. DISCUSSION: These results suggest that elderly women are less likely than younger women to receive timely breast cancer screening. The USPSTF does not recommend continued screening in elderly women because most studies of breast cancer efficacy included inadequate numbers of these women. Few, if any, studies have yielded evidence that screening is ineffective in women 70 and over. Given the higher breast cancer incidence and mortality seen in elderly women, as well as the increased life expectancy with little or no activity limitation seen among today's elderly, consideration should be given to including elderly women in the recommendation to receive timely breast cancer screening. Since surgical and adjuvant therapy for breast cancer in older women has less complications than therapy for other cancers of the elderly, the cost-benefit ratio for breast cancer screening in this age group may prove to be more promising.     

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.     

Opportunities for oral cancer screening among older African-American women

BACKGROUND: Older persons with smoking histories are important targets for oral cancer screening. Although older persons in low-income communities often lack regular dental care, little is known about the characteristics of groups at greatest risk for poor screening. METHODS: Survey data from 576 African-American women aged 45-93 were used to identify predictors of smoking and recency and type of dental care. RESULTS: Fifty-nine percent of respondents were current or former smokers, and 62% reported dental care within the past 3 years. Among smokers, no recent dental care was associated with older age, worse health, not working, no regular medical provider, and no recent mammography. CONCLUSIONS: These results suggest that episodic visits to non dentist providers offer opportunities for oral screening in high-risk populations.     

Reattendance of women for breast cancer screening programs. A review

BACKGROUND: In France, breast cancer is the most frequently occurring cancer and the leading cause of cancer deaths in women. Breast cancer screening has been shown to reduce breast cancer mortality by 30% provided attendance rate is 70% and re-screening interval is two to three years. Maintaining a high rate of reattendance is also important. The decline with time of completion rates of re-screening will lessen the benefits of a breast cancer screening program. METHODS: A review of published studies examining factors associated with attendance and reattendance to breast cancer screening. RESULTS: Positive views about initial screening are determining factors in reattendance: mammography should not be painful and embarrassing, appointments should be punctual and clinic staff courteous and supportive. Psychological factors influencing attendance also influence reattendance as does intention to participate, a major predictor of repeat participation and as do perceived susceptibility of breast cancer, perceived benefits of mammography, absence of emotional barriers. These factors can be modified by experience of previous screening. Other predicting factors of attendance continue to influence reattendance: practice of other preventive health behaviors, outside support from physicians, knowledge of breast cancer and screening. CONCLUSION: A better understanding of factors influencing attendance is necessary to increase the impact of breast cancer screening. Field studies are necessary to support the elaboration of publicity campaigns aimed at increasing participation.     

Asian-Islamic women and breast cancer screening: a socio-cultural analysis.

This article explores religious and socio-cultural issues relevant to breast cancer screening practices among older immigrant Asian-Islamic women in the U.S. Some of the Islamic tenets that facilitate breast cancer screening include cleanliness, prevention and individual responsibility in health promotion, diet and eating habits, and exercise, and those that hinder screening practice include gender and modesty considerations and patriarchal marital beliefs. Socio-cultural barriers include patient-physician communication and beliefs about cancer and cancer prevention. Recommendations to increase knowledge and practice of breast cancer screening within a religious and socio-cultural context are provided.     

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.     

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.     

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.     

Determinants of breast cancer screening among inner-city Hispanic women in comparison with other inner-city women.

A telephone survey of a random sample of Rhode Island women ages 40 and older residing in minority low-income census tracts--census tracts in the lowest quartile of a variety of socioeconomic indicators in which at least 5 percent of the population was classified as Hispanic or non-Hispanic black--was conducted in 1991, focusing on breast cancer screening. Hispanic women were found to have about half the breast cancer screening rate (20 percent, according to current screening guidelines) of other respondents (37 percent). Determinants of screening were explored to suggest reasons for this difference. The Health Belief Model was used to identify and compare determinants of breast cancer screening (sociodemographics, health care utilization, perceived susceptibility to breast cancer, perceived seriousness of breast cancer, cues to screening such as a provider''s recommendation, and the perceived benefits and costs of screening) among Hispanics, non-Hispanic whites, and non-Hispanic blacks. Hispanics were younger, less educated, and had lower family incomes than other women residing in minority low-income census tracts, were less likely to receive medical care, to perceive themselves as susceptible to breast cancer, and to perceive breast cancer as curable. Logistic regression analyses revealed the importance of use of health care, cues for screening, and perceptions of mammography to explain the screening behavior of Hispanics and non-Hispanics alike. Access to medical care is a significant problem in the Rhode Island Hispanic community, related to recent immigration, undocumented immigration, and low income characteristics of its members.(ABSTRACT TRUNCATED AT 250 WORDS)
