Abstract
We examined the factors associated with screening mammography adherence behaviors and influencing factors on women's attitudes toward mammography in non-adherent women. Design-based logistic regression models were developed to characterize the influencing factors, including socio-demographic, health related, behavioral characteristics, and knowledge of breast cancer/mammography, on women's compliance with and attitudes toward mammography using the 2003 Health Information National Trends Survey data. Findings indicate significant associations among adherence to mammography and marital status, income, health coverage, being advised by a doctor to have a mammogram, having had Pap smear before, perception of chance of getting breast cancer, and knowledge of mammography (frequency of doing mammogram) in both women younger than 65 and women aged 65 and older. However, number of visits to a healthcare provider per year and lifetime number of smoked cigarettes are only significant for women younger than 65. Factors significantly associated with attitudes toward mammography in non-adherent women are age, being advised by a doctor to have a mammogram, and seeking cancer information. To enhance adherence to mammography programs, physicians need to continue to advise their patients to obtain mammograms. In addition, increasing women's knowledge about the frequency and starting age for screening mammography may improve women's adherence. Financially related factors such as income and insurance are also shown to be significant factors. Hence, healthcare policies aimed at providing breast cancer screening services to underserved women will likely enhance mammography participation.

Abstract
BACKGROUND The rates of breast cancer have increased over the past two decades, and this raises concern about physical, psychological and social well-being of women with breast cancer. Further, few women really want to do breast cancer screening. We here investigated the socio-demographic correlates of mammography participation among 400 asymptomatic Iranian women aged between 35 and 69. METHODS A cross-sectional survey was conducted at the four outpatient clinics of general hospitals in Tehran during the period from July through October, 2009. Bi-variate analyses and multi-variate binary logistic regression were employed to find the socio- demographic predictors of mammography utilization among participants. RESULTS The rate of mammography participation was 21.5% and relatively high because of access to general hospital services. More women who had undergone mammography were graduates from university or college, had full-time or part-time employment, were insured whether public or private, reported a positive family history of breast cancer, and were in the middle income level (P <0.01).The largest number of participating women was in the age range of 41 to 50 years. The results of multivariate logistic regression further showed that education (95%CI: 0.131-0.622), monthly income (95%CI: 0.038-0.945), and family history of breast cancer (95%CI: 1.97-9.28) were significantly associated (all P <0.05)with mammography participation. CONCLUSIONS The most important issue for a successful screening program is participation. Using a random sample, this study found that the potential predictor variables of mammography participation included a higher education level, a middle income level, and a positive family history of breast cancer for Iranian women after adjusting for all other demographic variables in the model.

Abstract
BACKGROUND Breast cancer is the most common malignancy among women, and its timely diagnosis and treatment are of paramount importance, especially for vulnerable groups, such as low-income and uninsured women. Recent literature confirms that the method of breast cancer detection may be an important prognostic factor, but there are no studies that examine the method of breast cancer detection in low-income populations. We sought to analyze the determinants of method of detection (medical vs. self) in a cohort of low-income women with breast cancer receiving care through California's Breast and Cervical Cancer Treatment Program. METHODS This is a cross-sectional survey analysis of 921 low-income women interviewed within 6 months of definitive surgical treatment. The outcome analyzed was self vs. medical detection of breast cancer. RESULTS The mean age of the women was 53 years, with nearly 88% reporting an income of <$30,000 per year; 64% of women self-detected their breast cancer. Logistic regression analyses revealed that older women, Latinas, and women having any health insurance before diagnosis had lower odds of self-detecting their lesions. CONCLUSIONS Patient age, ethnicity, and regular source of care were associated with method of breast cancer detection in a low-income underserved population. The rate of self-detection in our population correlates with the literature, but we need to improve efforts to increase mammography screening to ensure early detection of disease in this vulnerable group.

Abstract
OBJECTIVE We analyzed information surveyed from a community-based sample of Korean women older than 40 years of age to understand the relationships between health status and screening behavior. METHODS In a cross-sectional population-based study, a two-stage, geographically stratified household-based sampling design was used for assembly of a probability sample of women aged 40-69 years living in Gunpo in Korea, resulting in a total sample size of 503 women. The primary outcome variable for this analysis was the respondent's intention to obtain a mammogram. Predictor variables included health status and other factors known to influence the use of cancer screening, such as age, education, income, marital status and the presence of co-morbid illnesses. Health status was assessed by using the EuroQol (EQ-5D). RESULTS The median EQ visual analogue scale score was 75.0, ranging from 20 to 100. In bivariate analyses, the percentage of women reporting to have intention toward mammography use decreased with worsening health status. Women who had problems with mobility or anxiety/depression showed lower intention to undergo future screening mammography. Multivariate logistic regression confirmed that health status was significantly associated with intention toward mammography use. Anxiety or depression was an independent predictor of future screening mammography use. CONCLUSIONS Health status is significantly associated with intention regarding screening mammography use. Physicians or other health professionals should be aware that health status is an important component for health promotion, and should pay more attention to clients' possible vulnerability in screening mammography use due to their poor health status.

Abstract
OBJECTIVE The objective of this study was to assess rural-urban differences in mammography and Papanicolaou (Pap) smear screening. METHODS Data from the Behavioral Risk Factor Surveillance System (1994-2000, 2002, 2004) were used to examine trends in these two tests by rural-urban residence location. RESULTS In 2004, 70.8 percent of rural and 75.7 percent of urban respondents had received timely mammography; this difference remained significant in adjusted analyses and was greatest for women in remote rural locations. Although overall participation in mammography increased over time, a persistent rural-urban gap was identified. In contrast, in 2004, while 83.1 percent of rural and 86.1 percent of urban respondents had received a timely Pap test, the adjusted difference was not significant and Pap testing did not improve over time. Advanced age and low socioeconomic status were associated with a lack of screening. CONCLUSIONS Over an 11-year interval, mammography screening improved nationally, but women living in rural locations remained less likely than their urban counterparts to receive this test. However, no secular improvement in Pap testing was found, and no significant rural-urban differences were observed. POLICY IMPLICATIONS Interventions to improve breast cancer screening are needed for rural women. Such efforts should target older women and those with low socioeconomic status.

Abstract
BACKGROUND Few studies have related stages of mammography screening nonadherence with the rationale used by overdue women. METHODS We used a grounded theory approach to obtain and analyze data from focus groups, telephone interviews, and surveys. Emergent specific themes were compared with emerging decision levels of nonadherence. Each decision level was then compared with the Precaution Adoption Process Model and the Transtheoretical Model. RESULTS A total of 6 key themes influencing mammogram nonadherence emerged as did 6 decision levels. Variability within themes was associated with specific decision levels. The decision levels were not adequately classified by either stage model. CONCLUSIONS Stage-based educational strategies may benefit by tailoring interventions to these 6 decision levels.

Abstract
Women with inadequate health insurance have lower mammography rates than the general population. Finding successful strategies to enroll eligible women is an ongoing challenge for the National Breast and Cervical Cancer Early Detection Program. To test the effectiveness of a population-based strategy to increase mammography utilization among low-income underinsured women ages 40 to 64 years, a randomized trial was conducted to assess the effect of two mailed interventions on mammography utilization through Sage, the National Breast and Cervical Cancer Early Detection Program in Minnesota. Women (N = 145,467) ages 40 to 63 years [mean (SD), 49.7 (6.8)] with estimated household incomes below 50,000 US dollars (47.9% were < 35,000 US dollars) from a commercial database were randomized to three groups: Mail, Mail Plus Incentive, or Control. Both the Mail and the Mail Plus Incentive groups received two simple mailings prompting them to call a toll-free number to access free mammography services. The Mail Plus Incentive intervention offered a small monetary incentive for a completed mammogram. After 1 year, both intervention groups had significantly higher Sage mammography rates than the Controls, and the Mail Plus Incentive group had a significantly higher rate than the Mail group. The Mail and Mail Plus Incentive interventions were estimated to produce increases in Sage screening rates of 0.23% and 0.75%, respectively, beyond the composite Control rate of 0.83%. Direct mail is an effective strategy for increasing mammography use through Sage. Coupling direct mail with an incentive significantly enhances the intervention's effectiveness. Direct mail should be considered as a strategy to increase mammography use among low-income, medically underserved women.

Abstract
INTRODUCTION Identifying communities with lower rates of mammography screening is a critical step to providing targeted screening programs; however, population-based data necessary for identifying these geographic areas are limited. This study presents methods to identify geographic disparities in the early detection of breast cancer. METHODS Data for all women residing in Dane County, Wisconsin, at the time of their breast cancer diagnosis from 1981 through 2000 (N = 4769) were obtained from the Wisconsin Cancer Reporting System (Wisconsin's tumor registry) by ZIP code of residence. Hierarchical logistic regression models for disease mapping were used to identify geographic differences in the early detection of breast cancer. RESULTS The percentage of breast cancer cases diagnosed in situ (excluding lobular carcinoma in situ) increased from 1.3% in 1981 to 11.9% in 2000. This increase, reflecting increasing mammography use, occurred sooner in Dane County than in Wisconsin as a whole. From 1981 through 1985, the proportion of breast cancer diagnosed in situ in Dane county was universally low (2%-3%). From 1986 through 1990, urban and suburban ZIP codes had significantly higher rates (10%) compared with rural ZIP codes (5%). From 1991 through 1995, mammography screening had increased in rural ZIP codes (7% of breast cancer diagnosed in situ). From 1996 through 2000, mammography use was fairly homogeneous across the entire county (13%-14% of breast cancer diagnosed in situ). CONCLUSION The percentage of breast cancer cases diagnosed in situ increased in the state and in all areas of Dane County from 1981 through 2000. Visual display of the geographic differences in the early detection of breast cancer demonstrates the diffusion of mammography use across the county over the 20-year period.

Abstract
Purpose The purpose of this study is to describe the factors associated with the decisions of older African American women to join the PLCO (Prostate, Lung, Colorectal and Ovarian) Cancer Screening Trial when recruited. Methods African American women between ages 55 and 74 years who were never diagnosed with a PLCO cancer were eligible for our study. Two methods of recruitment were used. First, mailings were sent to a random sample of women describing the PLCO followed by a telephone call to determine interest in the PLCO. If women were not interested in PLCO but consented to participate in our study, they were interviewed immediately. Second, we followed up with African American women who responded to mass mailings sent out before the start of our study by the Pittsburgh PLCO office. Women completed an interview about their cancer and clinical trial knowledge, attitudes, beliefs, and behaviors. The responses of women who joined the PLCO Trial are contrasted with the responses of women who did not join. Results Numerous factors were associated with the decision of older African American women to join the PLCO, including perceptions of cancer prevention and detection, the experience of having a loved one with cancer, knowledge of and experience with clinical trials, and beliefs regarding the benefits and risks of clinical trial participation. Conclusion Minority recruitment to cancer clinical trials could be increased by designing interventions focused on individual, organizational, and community needs.

Abstract
BACKGROUND Health care delivery varies with the level of managed care activity (MCA) in an area, potentially affecting health care for those not participating in managed care programs. However, the extent to which MCA is associated with the use of cancer screening by fee-for-service beneficiaries (FFS) is unclear. OBJECTIVE We sought to study colorectal cancer screening among Medicare FFS beneficiaries in relation to levels of Medicare MCA. RESEARCH DESIGN This study linked 1999 Medicare denominator and Part B claims data with the 1998 Area Resource File. After categorizing MCA as low (<10%), moderate (10-29.99%), or high (> or =30%), we assessed the association between colorectal cancer screening among FFS beneficiaries and MCA, controlling for individual demographic variables and county-level attributes of socioeconomic status and physician resources. SUBJECTS We included Medicare FFS beneficiaries 65 years of age or older with both Part A and Part B coverage for the entire calendar year from large counties in the study. MEASURES We measured the likelihood of undergoing fecal occult blood testing (FOBT), flexible sigmoidoscopy (FLEX), or colonoscopy (COL). RESULTS Compared with Medicare FFS beneficiaries residing in counties with low MCA, those in high MCA counties were significantly more likely to undergo FOBT (adjusted odds ratio [AOR] 1.10, 95% confidence interval [CI] 1.04-1.16), FLEX (AOR 1.11, 95% CI 1.04-1.18), or colonoscopy, after receiving FOBT/FLEX (AOR 1.07, 95% CI 1.02-1.13). CONCLUSIONS From a public health perspective, an association between higher levels of MCA and colorectal cancer screening among those not enrolled in managed care may translate into modest increases in use of colorectal cancer screening and possibly earlier detection.

Abstract
OBJECTIVE: To examine theory-based selected factors associated with adherence to mammography screening guidelines in a surveillance database. METHODS: Data from Colorado Mammography Project (CMAP) from 1994-1998 was extracted and analyzed by using SAS statistical software. Based on the Health Belief Model and Behavioral Model of Health Services Utilization a prediction model was developed to examine the mammography utilization patterns and factors influencing the adherence to screening guidelines. RESULTS: Out of 27,778 women, 41.4% were adherent with mammography screening guidelines. According to the model tested in this study, race/ethnicity (Black vs White, OR=0.76, 95% CI=0.64-0.91); educational attainment (high school vs < high school, OR= 1.10, 95% CI= 1.04-1.18), college graduate vs < high school (OR=1.33, 95% CI=1.25-1.42); insurance status, (any coverage vs no coverage (OR=1.62, 95% CI=1.25-2.12); and community economic status as defined by median income by zip code of residence ($15,000-$24,999 vs <$15,000, OR=0.84, 95% CI=0.76-0.94; >$55,000 vs <$15,000, OR 1.14, 95% CI=1.03-1.26) were statistically significant predictors of adherence to guidelines. Interaction between age and family history of breast cancer was statically significant. Younger females with a family history of breast cancer were less likely to be adherent than their counterparts without a family history (OR=0.93, 95% CI=0.90-0.96). Inclusion or exclusion of women aged 70 years and older did not change the outcome of the analysis. CONCLUSION: The prediction model variables such as race/ethnicity, age and family history of breast cancer, educational level and community economic status, are associated with adherence status. Family history of breast cancer needs to be examined very carefully in future studies as it may play negative role in adherence to screening mammography.

Abstract
INTRODUCTION In Spain, the degree and characteristics of primary care services utilization have been the subject of analysis since at least the 1980s. One of the main reasons for this interest is to assess the extent to which utilization matches primary care needs. In fact, the provision of an adequate health service for those who most need it is a generally accepted priority. FACTORS CONDITIONING USE The evidence shows that individual characteristics, mainly health status, are the factors most closely related to primary care utilization. Other personal characteristics, such as gender and age, could act as modulators of health care need. Some family and/or cultural variables, as well as factors related to the health care professional and institutions, could explain some of the observed variability in primary care services utilization. Socioeconomic variables, such as income, reveal a paradox. From an aggregate perspective, income is the main determinant of utilization as well as of health care expenditure. When data are analyzed for individuals, however, income is not related to primary health utilization. METHODOLOGICAL INCONSISTENCIES The situation is controversial, with methodological implications and, above all, consequences for the assessment of the efficiency in primary care utilization. Review of the literature reveals certain methodological inconsistencies that could at least partly explain the disparity of the empirical results. Among others, the following flaws can be highlighted: design problems, measurement errors, misspecification, and misleading statistical methods.Some solutions, among others, are quasi-experiments, the use of large administrative databases and of primary data sources (design problems); differentiation between types of utilization and between units of analysis other than consultations, and correction of measurement errors in the explanatory variables (measurement errors); consideration of relevant explanatory variables (misspecification); and the use of multilevel models (statistical methods).

Abstract
Despite recent controversies in mammography efficacy, encouraging women to obtain regular screenings is still an important public health priority. Published articles about repeat or regular screening were reviewed to determine trends in rates of mammography adherence. A search of MEDLINE and PsycINFO from January 1990 to December 2001 identified 45 empirical articles of U.S. samples that reported, or provided sufficient data to calculate, the percentage of women 50 years of age and older who obtained 2 or more consecutive, on-schedule mammograms. Keywords used in the searches included pairing mammography with regular, repeat, adherence, compliance, annual, rescreen, and maintenance. The weighted average repeat mammography percentage across all eventually included studies (N = 37) was 46.1% (confidence interval: 39.4%, 52.8%). There was no substantial difference in the average repeat screening percentages comparing studies that collected data from 1995 to 2001 versus 1991 to 1994. Within each of 3 time periods of data collection (pre-1991, 1991-1994, 1995-2001), there was substantial variation in repeat rates. This variation appears to be due to several characteristics of study design and sampling, including the definition/methods of collecting data about the adherence measure, prior mammography status, and use of an upper age limit at recruitment. Consensus is needed regarding the definition of repeat mammography. National surveys must include items to assess repeat mammography in order to have estimates that accurately represent population-level rates. Although this study involved mammography, similar challenges in assessing prevalence rates can occur with other screening behaviors.

Abstract
BACKGROUND In this article we estimate the variations in receipt of age-appropriate preventive services among adult women between 21 and 64 years of age, by race and ethnic group, socioeconomic status, and access to health care. We also assess whether differences in access to care and socioeconomic status may explain racial and ethnic differences in the use of preventive services. METHOD Nationally representative data on adult women from the Medical Expenditure Panel Survey were used to estimate the effect of socioeconomic characteristics on the receipt of each preventive service. Receipt of each of four preventive services-cholesterol test, blood pressure reading, and two cancer screening tests (Papanicolaou smear, mammogram)-according to the 1996 recommendations of the U.S. Preventive Services Task Force were examined. RESULTS An overwhelming majority of adult women (93%) had had a blood pressure reading within the last 2 years. Eighty-four percent of women had had their cholesterol checked within the last 5 years. Seventy-five percent of women had received a mammogram and 80% received Pap tests. College education, high income, usual source of care, and health insurance consistently predicted use of preventive services. These factors also explained ethnic disparities in the receipt of preventive services between Latinas and white women. CONCLUSIONS The results from our study are encouraging because only a minority of women do not receive age-appropriate preventive services. However, low socioeconomic status, lack of insurance, and lack of a usual source of care represent significant barriers to preventive care for adult women.

Abstract
The effect on women's breast cancer screening utilization of a barrier-specific telephone counseling (BSTC) intervention, with and without a concurrent continuing medical education (CME) activity for their physicians, was evaluated. All participants (50-80 years of age) were not regular mammography users at baseline. A 4-arm quasi-experimental design was employed. Women were randomized to the BSTC or no BSTC group and assigned (with their physicians) to the CME or no CME group based on place of residence. Pre- and postintervention data were obtained for 1,601 women using telephone interviews conducted during 1995 and 1998, respectively. Among women who had ever used mammography at baseline, those who received BSTC were more likely than the control group to become regular mammography users at follow-up (OR = 1.4, p = .033). Greater reductions in perceived barriers to mammography, from baseline to follow-up, were significantly associated with receiving BSTC compared with the control group (p = .001), among women with previous mammography experience. Findings suggest that CME may have potential for initiating mammography use among women who never had a previous mammogram. However, because of the small sample available for analyses of the CME intervention and differential attrition among women who never had a previous mammogram, further study is needed to confirm this hypothesis.

Abstract
OBJECTIVE To explore patterns of adherence to guidelines for screening mammography among participants in the Colorado Mammography Project (CMAP) surveillance database. METHODS An algorithm was developed to assess factors associated with adherence to mammography screening guidelines. RESULTS Of the 27,778 women ranging from 40-90 years of age included in the analysis, 41.4% were adherent with mammography screening guidelines. According to the model tested in this study, race/ethnicity (Black vs White, OR=0.76, 95% CI=0.64-0.91); educational attainment (high school vs <high school, OR=1.10, 95% CI=1.04-1.18, college graduate vs <high school OR=1.33, 95% CI=1.25-1.42); insurance status, (any coverage vs no coverage, OR=1.62, 95% CI=1.25-2.12); and community economic status as defined by median income by zip code of residence (15,000 dollars-24,999 dollars vs <15,000 dollars, OR=0.84, 95% CI=0.76-0.94, >55,000 dollars vs <15,000 dollars, OR 1.14, 95% CI=1.03-1.26) were statistically significant predictors of adherence to guidelines. A significant interaction between age and family history of breast cancer (BC) was also found. Younger females with a family history of BC were less likely to be adherent than their counterparts without a family history (OR=0.93, 95% CI=0.90-0.96). In general, elderly women were more likely to be adherent compared with the youngest group in this cohort (OR=1.21, 95% CI=1.11-1.33). Inclusion or exclusion of women aged 70 years and older did not change the outcome of the analysis. CONCLUSION Adherence with screening mammography guidelines was found to be associated with women's personal characteristics including race/ethnicity, age, and family history of BC. In addition, socioeconomic status, as measured by educational level and community economic status, are important predictors of adherence. Efforts to increase adherence may need to be specific to race/ethnic group and age, but the effect of age is mediated by family history of BC and vice versa.

Abstract
STUDY OBJECTIVE There is an increasing body of evidence about socioeconomic inequality in preventive use, mostly for cancer screening. But as far as needs of prevention are unequally distributed, even equal use may not be fair. Moreover, prevention might be unequally used in the same way as health care in general. The objective of the paper is to assess inequity in prevention and to compare socioeconomic inequity in preventive medicine with that in health care. DESIGN A cross sectional Health Interview Survey was carried out in 1997 by face to face interview and self administered questionnaire. Two types of health care utilisation were considered (contacts with GPs and with specialists) and four preventive care mostly delivered in a GP setting (flu vaccination, cholesterol screening) or in a specialty setting (mammography and pap smear). SETTING Belgium. PARTICIPANTS A representative sample of 7378 residents aged 25 years and over (participation rate: 61%). OUTCOME MEASURE Socioeconomic inequity was measured by the HI(wvp) index, which is the difference between use inequality and needs inequality. Needs was computed as the expected use by the risk factors or target groups. MAIN RESULTS There was significant inequity for all medical contacts and preventive medicine. Medical contacts showed inequity favouring the rich for specialist visits and inequity favouring the poor for contacts with GPs. Regarding preventive medicine, inequity was high and favoured the rich for mammography and cervical screening; inequity was lower for flu immunisation and cholesterol screening but still favoured the higher socioeconomic groups. In the general practice setting, inequity in prevention was higher than inequity in health care; in the specialty setting, inequity in prevention was not statistically different from inequity in health care, although it was higher than in the general practice setting. CONCLUSIONS If inequity in preventive medicine is to be lowered, the role of the GP must be fostered and access to specialty medicine increased, especially for cancer screening.

Abstract
BACKGROUND Underutilization of breast and cervical cancer screening has been observed in many ethnic groups and underserved populations. Effective community-based interventions are needed to eliminate disparities in screening rates and thus to improve prospects for survival. METHODS The Breast and Cervical Cancer Intervention Study was a controlled trial of three interventions in the San Francisco Bay Area from 1993 to 1996: (1) community-based lay health worker outreach; (2) clinic-based provider training and reminder system; and (3) patient navigator for follow-up of abnormal screening results. Study design and a description of the interventions are reported along with baseline results of a household survey conducted in four languages among 1599 women, aged 40-75. RESULTS Seventy-six percent of women ages 40 and over had had at least one mammogram, and most had had a clinical breast examination (88%) and Pap smear (89%). Rates were significantly lower for non-English-speaking Latinas and Chinese women (56 and 32%, respectively, for mammography), and maintenance screening (three mammograms in the past 5 years) varied from 7% (non-English-speaking Chinese) to 53% (Blacks). Pap smear screening in the past 3 years was low among non-English-speaking Latinas (72%) and markedly lower among non-English-speaking Chinese women (24%). The strongest predictors of screening behavior were having private health insurance and frequent use of medical services. Having a regular clinic and speaking English were also important. Race/ethnicity, education, household income, and employment status were, overall, not significant predictors of screening behavior. CONCLUSIONS These baseline results support the importance of cancer screening interventions targeted to persons of foreign origin, particularly those less acculturated.

Abstract
This study sought to explore the contribution of the self-concept to older women's adherence to regular mammography screening behavior. The PRECEDE and health belief model concepts were incorporated with a measure of the women's future selves to determine whether the self-concept adds to our ability to predict screening. A self-administered questionnaire was completed by 210 community-dwelling women ages 50 to 75 years, recruited from urban and rural women's groups. Logistic regression analyses revealed that predictors of adherence were clinical breast examination, physician recommendation, age, barriers, benefits, feared health-related possible self, and self-efficacy in the feared domain. The addition of the self measures significantly improved the overall fit of the model. Implications for theory development, practice, and future research are discussed.

Abstract
Using concepts from the Precaution Adoption Process Model, we identified behavioral factors, sociodemographic and psychosocial variables, and beliefs about breast cancer that discriminated among women at different stages with regard to their intention to obtain mammography screening. An independent survey company conducted telephone interviews with 2,507 women aged 50 to 80 who were identified as underutilizers of mammography screening. Each underutilizer was assigned to one of three stages with regard to intention to get a mammogram: (a) definitely planning, (b) thinking about, and (c) not planning. Estimated actual risk of breast cancer, perceived risk to breast cancer, worry about breast cancer, and fear of learning from a mammogram that one has breast cancer were variables found to be significantly associated with intention to obtain a mammogram for several subgroups of underutilizing women. There are significant behavioral and psychosocial variables, beliefs and feelings about breast cancer, and demographic characteristics that distinguish underutilizing women at various stages with regard to intention to obtain mammography screening. Our findings provide new information that could help the health care professional motivate women who are not planning to utilize this preventive health measure to become regular utilizers.

Abstract
Factors associated with the level of utilization of screening mammography as a preventive practice were analyzed prior to initiating a population-based breast cancer screening program. A questionnaire was used to collect information about screening mammography utilization during the last 4 years among women invited to enroll in the program. Sociodemographic and health factors, and health services utilization were studied. A screening mammography in the last 4 years had been performed on 59.3% of the 8867 women interviewed. The utilization of mammography was higher among women who were younger, had a higher education level, or had previous visits to a physician (P < 0.001). The variables more strongly associated with use of screening mammography were: visit to a gynecologist and performance of a pap smear. Also associated with the utilization of screening mammography were: personal history of breast pathology, family history of breast cancer, breast self-examination, and recent visit to a general practitioner. Self-perceived health presented an inverse relation with screening mammography use (P < 0.001). The use of screening mammography appears to have increased in recent years, although inequalities persist which the breast cancer screening programs help to modulate. Mammographic frequency only would be deemed appropriate by the European guidelines in fewer than one-half of the cases.

Abstract
The purpose of this research was to revise scales measuring perceived susceptibility to breast cancer and perceived benefits and barriers to mammography utilization. A total of 618 women age 50 and over who were enrolled in a large intervention study participated in data collection. Scales were revised beginning with focus group input. Analyses included internal consistency reliability, test-retest reliability, factor analysis, confirmatory analysis, and known groups techniques to test construct validity. Internal consistency ranged from .75 to .88, and test reliabilities from .59 to .72. Construct validity was confirmed with exploratory and confirmatory factor analyses, as well as known group techniques. Overall these scales represent an improvement in those previously reported.

Abstract
BACKGROUND Implicit in "any willing provider" and "freedom of choice" legislation is the assumption that ongoing provider relationships lead to better patient outcomes on average. Although previous studies have identified associations of usual source of care with medical utilization, its relationship to patient lifestyle has not been examined. OBJECTIVE To determine the effect of having a usual physician on health behaviors. METHODS Data on 3,140 adults from the 1995 Mid-Life in the US study were used to estimate logistic regressions of the effect of having a usual physician on exercise, obesity, vitamin-taking, smoking quits, substance abuse behaviors, preventive medical visits, and respondent assessments of the ability to affect one's own health and risk of heart attacks and cancer. RESULTS Respondents with a usual physician were 3 times as likely to have had a preventive medical visit during the past year. Among lower-income respondents, those with usual physicians were one-half as likely to report substance abuse behaviors. Instrumenting reduced the magnitude of the former but not latter effect. No other significant differences were found. CONCLUSIONS Strategies designed to foster regular patient-provider relationships may affect certain health behaviors, such as preventive care visits and substance abuse. Yet in the absence of interventions to improve the effectiveness of these relationships, they are unlikely to be a powerful policy instrument for achieving widespread improvements in patient lifestyle choices.

Abstract
This study examines the relationship between family history of breast cancer and current compliance with mammography screening guidelines. A random telephone survey of women age 40 or older living in rural Wisconsin (N = 2398) was conducted to determine mammography screening knowledge, family history of breast cancer, attitudes, intentions, physician recommendation, and compliance with screening guidelines. Compared with women without a family history of breast cancer, women with a family history were significantly more likely to demonstrate correct knowledge (p = 0. 01); express intentions in compliance with recommended screening guidelines (p < 0.001); report having been advised by a physician to obtain a mammogram (p < 0.001); and be in current compliance with mammography screening guidelines (p < 0.001). Results of simultaneous and individual logistic regression suggest that the effects of family history on compliance with screening guidelines are directly mediated through the combination of women's knowledge, women's intentions, and physician recommendation. Thus, programs to increase compliance with mammography screening guidelines should address both women and providers.

Abstract
INTRODUCTION Uneven increases in mammography utilization rates call for methods to efficiently target educational interventions to women who do not regularly use mammography and physicians who do not adhere to national guidelines for breast cancer screening. This paper discusses a method for identifying physicians who are nonadherers to breast cancer screening guidelines or in need of continuing medical education (CME) in this area. METHODS A 1995 community-based telephone survey of randomly selected women aged 50-80, residing in four Long Island, NY, townships was used to identify women who underuse mammography and their regular physicians. Community-based surveys of physicians permitted identification of nonadherent providers. Nonadherence to breast cancer screening recommendations was the primary criterion, but because of anticipated physician reluctance to self report nonadherence with screening guidelines, additional criteria were developed to identify physicians with educational needs relating to breast cancer screening. These criteria included lack of office reminder systems and knowledge relating to breast cancer screening, and lack of confidence in patient counseling and clinical breast examination skills. RESULTS Overall response rates were 77% for women's survey, and 66% for the physician survey. 3427 women were classified as underusers (38.5%) and 87% of underusers provided the name and address of their regular physicians. By physician self report, 45% of physicians were classified as nonadherers and 42% were identified as having related educational needs. CONCLUSION A feasible method for identifying physicians who are nonadherers to breast cancer screening recommendations or in need of CME about this is described, permitting efficient targeting of educational interventions to those with patients who underuse mammography. The method is not dependent on access to a specific provider or patient population.

Abstract
The study explores knowledge, attitudes and behavior regarding screening for breast and cervical cancers. All female teachers in primary and secondary schools in Crotone and in Cassino (Italy) received a questionnaire on demographic and socioeconomic characteristics, clinical history, knowledge, behavior and attitudes about breast and cervical cancer and related screening procedures. A response rate of 65% was achieved. Knowledge on effectiveness of mammography and pap test in finding related cancers was widely spread in the sample. Only about 30% and 50% had respectively undergone their last mammogram and pap test according to the recommended time interval. Having been examined by a physician in the previous year and having had a screening CBE or a screening pap smear in the past three years were significantly more likely in women who underwent mammography for screening purposes in the past two years. Pap smear in the previous three years was significantly more likely in women in their forties, with a higher family income and in those who had been examined by a physician in the previous year. The results strongly recommend continued emphasis of physicians on education of women regarding mammography and pap smear.

Abstract
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.

Abstract
BACKGROUND In this paper two large nationwide trials are described, both of which will test a comparable telephone-based counseling intervention to promote cancer screening among the first-degree relatives (FDRs) of breast and colorectal cancer patients. The unit of randomization will be the family unit of eligible FDRs. Access to FDRs will be obtained from their relatives with cancer. Selected intervention and design issues are reviewed, including how both projects will respond to FDRs who exhibit significant levels of cancer-specific anxiety or distress and how potential high-risk cancer families will be accommodated. METHODS Pursuant to the development of both studies, two feasibility surveys were conducted to determine whether patients would grant access to their FDRs and whether the FDRS identified by these patients would be receptive to the telephone intervention. RESULTS Approximately 80% (106 of 132) of breast cancer patients agreed to provide access to their eligible FDRs when contacted on-site at participating hospitals and clinics. Of those subsequently selected for telephone follow-up (n = 95 or 90%), 80% (n = 76) were successfully contacted by telephone, and of these 97% (n = 74) provided the names and telephone numbers of their FDRs. Among colorectal cancer patients contacted on-site (n = 46), 96% (n = 44) agreed to provide access to their FDRs, and of those contacted by telephone (n = 33 or 75%), 91% (n = 30) provided the requested information about their FDRs. Once contacted, 95% of breast cancer FDRs (55 of 58) and 91% of colorectal cancer patients (51 of 56) endorsed the intervention strategy. CONCLUSIONS It is argued that this intervention, if proven effective, could provide an exportable strategy for reaching large numbers of high-risk individuals to promote cancer screening.

Abstract
Crosslinked hydrophilic copolymers have the potential to be used as breast phantom materials because they can be made to have similar elemental composition to that of body soft tissues. The copolymer, which consists of a combination of hydrophobic monomers (methyl methacrylate [MMA]) and hydrophilic monomers (vinylpyrolidone [VP]), have all the required major elements, such as hydrogen, carbon, nitrogen, and oxygen, found in tissues. Photon attenuation measurements were performed on the crosslinked hydrophilic copolymers in order to ascertain whether they are good representatives of breast tissues in the photon energy range of interest. The results of the measurements of transmission of photons by the hydrophilic copolymers at different discrete energies between 10 and 60 keV are presented.

Abstract
Little is known about the health behaviors of church attendees. This article reviewed telephone interview data of 1,517 women who were church members from 45 churches located in Los Angeles County to determine their breast cancer screening status and to identify the key predictors of screening. Almost all of this sample (96%) reported attending church at least once a month. Key predictors of screening included physician-patient communication, ethnic background, and having medical insurance. Although church-related predictors were not significantly related to screening adherence, the authors compared community-based screening rates from another sample to their sample rates and found that, when controlling for income and education, church members fared better on mammography screening than women who were community residents. This finding suggests that frequent church attendance contributes to better mammography screening status and that the relationship between religious involvement and health behaviors needs further explanation.

Abstract
BACKGROUND This study prospectively examined rates of adherence to mammography, clinical breast examination (CBE), and breast self-examination (BSE) in a cohort of women over 3 years to determine whether participation in BSE influenced participation in the other two screening modalities. METHODS Women ages 51 and older (n = 450) who attended a small group educational session to learn BSE and to hear about CBE and mammography guidelines were assessed annually by telephone for 3 consecutive years to determine their subsequent breast cancer screening behavior. RESULTS Annual CBE and mammography screening are highly positively associated. Regular performance of BSE has a modest positive association with both CBE and mammography adherence over time. CONCLUSIONS Women who perform BSE regularly over time may be more likely to adhere to the other breast cancer screening guidelines.

Abstract
BACKGROUND The Mammography Quality Standards Act (MQSA) became effective October 1, 1994, and requires all mammography facilities to meet quality standards as promulgated by the Food and Drug Administration (FDA). The FDA undertook an assessment of the MQSA federal certification requirements on the availability of mammography facilities. METHODS A survey of states on mammography facility closures between October 1, 1993, and October 1, 1994, was conducted. MapInfo software was used to link zip codes to demographic databases. The characteristics of closed facilities were compared to certified facilities as of December 15, 1994. RESULTS A total of 369 facilities (3.5%) had closed. This closure rate was comparable to previous years' rates (2.5-10%). As of December 15, 1994, 10,142 certified facilities were operating. Relative to their distribution in the United States, closures in rural areas were proportional, but there were more facility closures in the minority areas and in poverty areas. However, the relative distributions of facilities to these areas' populations were unchanged. CONCLUSIONS Impact on facility availability has been minimal.

Abstract
We undertook this study to test whether progressive intervention would increase the use of mammography. In 1995, we randomly assigned into 2 groups 717 underserved women veterans in the Veterans Affairs Palo Alto (California) Health Care System (VAPAHCS) who earned less than $22,000 a year. The women were sent an informational letter and brochure explaining why mammography is needed and how often. The letter further requested that if the woman was due for a screening mammogram or if a lump or other recent change in her breast had occurred, that she call for scheduling of a free mammogram and a visit to the breast clinic. Women in group I (n = 351) received no further intervention. Women in group II (n = 366) received a follow-up phone call by a breast care nurse if they had not responded within 45 days of the informational mailing. The nurse talked to each woman about her particular needs, explained to her that the screening mammogram would be provided free of charge, and discussed transportation arrangements to the mammography facility. A total of 17 women in group I had mammograms versus 100 in group II during the same time period. We conclude that the additional intervention of a phone call by a breast care nurse increased use by more than 5-fold, which reached significance (P < .01).

Abstract
BACKGROUND This study evaluated the impact of a telephone outcall intervention (based on the Transtheoretical Model) on screening mammography behavior among lower income, older women. METHODS A geodemographic database, INFORUM, was used to identify low-income and minority neighborhoods throughout the state of Colorado. Residences were assigned randomly to three study groups: (1) control, (2) outcall only, and (3) advance "invitation" + outcall. Information Specialists of the Cancer Information Service implemented the protocol. Mammography adherence was assessed in telephone interviews conducted 6 months and 2 years after the initial call. RESULTS Neither intervention had a significant effect on the main outcome, receipt of mammography in the 6-month follow-up period. At 6 months, intentions to have a mammogram were significantly stronger in the intervention groups compared with the control group, particularly among those who were precontemplators at baseline. The 2-year follow-up indicated a small increase in mammography adherence attributable to the advance invitation + outcall, but this effect was restricted to those adherent at baseline. Mammography behavior during the 6-month follow-up period was predicted strongly by decisional balance, intentions, receipt of a physical and clinical breast exam, and previous mammography behavior. CONCLUSIONS The intervention promoted minimal movement in the stages of change for mammography. Outcall interventions may have promise for encouraging repeat mammography behavior, but more intensive interventions are likely to be necessary to promote behavior change among nonadherent women.

Abstract
BACKGROUND The telephone information service of the Cancer Information Service (CIS) historically is most effective in eliciting calls from higher income, white women. This article describes the design and feasibility of a project that tested the use of telephone outcalls to extend the reach of the telephone information service to underserved women. METHODS Neighborhoods throughout Colorado were identified using a geodemographic database (INFORUM) that allowed selection of census block groups according to demographic characteristics. Households were assigned randomly to: (1) a control group; (2) an outcall-only group, which received "cold" telephone outcalls promoting screening mammography; and (3) an advance card plus outcall group, which received a card introducing the program prior to the outcall. RESULTS The use of INFORUM to target low-income, less educated, and black women was largely successful. While quality of intervention delivery was high, the protocol was labor intensive, requiring an average of 40 min to identify and counsel each eligible woman. The advance card did not increase acceptance of the outcalls. CONCLUSIONS This approach successfully extended the CIS's audience; however, its labor intensity may limit its applicability. Strategies for increasing the efficiency of outcall efforts are suggested.

Abstract
OBJECTIVE To examine individual and environmental factors associated with adherence to mammography screening guidelines. DATA SOURCES A unique data set that combines a national probability sample (1992 National Health Interview Survey); a national probability sample of mammography facility characteristics (1992 National Survey of Mammography Facilities); county-level data on 1990 HMO market share; and county-level data on the supply of primary care providers (1991 Area Resource File). STUDY DESIGN The design was cross-sectional. DATA EXTRACTION/ANALYSIS: Data sets were linked to create an individual-level sample of women ages 50-74 (weighted n = 2,026). We used multipart, sequential logistic regression models to examine the predictors of having ever had mammography, having had recent mammography, and adherence to guidelines. We categorized women as adherent if they reported a lifetime number of exams appropriate for their age (based on screening every two years) and they reported having had an exam in the past two years. PRINCIPAL FINDINGS Only 27 percent of women had the age-appropriate number of screening exams (range 16 percent-37 percent), while 59 percent of women had been screened within two years. Women were significantly more likely to adhere to screening guidelines if they reported participating with their doctor in the decision to be screened; were younger; had smaller families, higher education and income, and a recent Pap smear; reported breast problems; and lived in an area with a higher percentage of mammography facilities with reminder systems, no shortage of primary care providers, higher HMO market share, and higher screening charges. CONCLUSIONS A small percentage of women adhere to screening guidelines, suggesting that adherence needs to become a focus of clinical, programmatic, and policy efforts.

Abstract
Despite the effectiveness of mammography as a method to detect breast cancer in women ages 50 and older, many women do not obtain screening mammograms. This study used the self-reported mammography history and demographic information obtained during the screening of 2453 post-menopausal women ages 50 to 79 at the San Diego Women's Health Initiative (WHI) center. We used this data to examine individual and social factors that predict mammography use. The WHI center comprised two clinics, one of which focused on Hispanic recruitment and thus provided the opportunity to examine the roles of ethnicity, income, education, marital status, age, and access to medical services on mammography use. Bivariate analysis indicated that the following factors were all strongly associated with women having had a mammogram in the previous two years: having health insurance, a regular medical provider, an annual household income greater than $20,000, and a high-school diploma, as well as being 65 years or older or white (P < 0.001). Multiple logistic regression analysis demonstrated that, when adjusting for all of these factors, having a medical provider (P < 0.001) was significant. Having insurance (P = 0.04) was suggestive, but did not meet the multiple-comparisons significance cutoff of P = 0.006. After adjusting for the above factors, it was found that ethnicity was not significant. The results suggest that improved access to a regular provider could increase the use of screening mammography in underserved populations.

Abstract
The age-adjusted incidence of breast cancer among U.S. women rose by over 30% during the 1980s. Several population-based studies have concluded that most or all of this observed increase is an artifact of the lead time afforded by mammography screening rather than an indication of a true increase in the rate at which women develop the disease. We conducted a study of the social construction of breast cancer trends as a public health problem in popular U.S. magazines. We documented trends in popular magazine article coverage of breast cancer between 1980 and 1995. In addition, we analyzed the content of a convenience sample of 228 popular magazine articles published between 1987 and 1995, focusing on a subsample of articles (n = 91) that mention the increase in breast cancer incidence. Our results show that the increase in incidence is commonly portrayed as a mysterious, unexplained epidemic occurring primarily among young, professional women in their prime years. Many articles suggest that recent changes in women's behavior such as increases in delayed childbearing, nulliparity, the use of oral contraceptives, induced abortion, and the use of tobacco and alcohol are related to the recent upsurge in the disease. The portrayal of the breast cancer epidemic in the U.S. popular press reflects a strong social desire to create order and control over a frightening disease. In the process, a common message is that the behaviors and choices of young, nontraditional women especially those related to fertility control-have led to pathological repercussions within their bodies, which in turn may be responsible for great disorder and pathology at the societal level in the epidemic of breast cancer.

Abstract
We examined mammography use patterns of women veterans and explored Veterans Administration (VA) health care use and military experience as predictors of mammography use by this population. We conducted a national telephone survey of women veterans. A sample of 397 women veterans was selected from all military discharges from 1971 through 1994. A 3 x 2 stratification scheme was used: three age groups (35-49, 50-64, > or = 65 years old) and two VA user groups indicating whether (VA user) or not (VA nonuser) they received any health care from a VA Medical Center in the last 5 years. The response rate was 75% (297 of 397). Analyses included bivariate techniques and weighted logistic regression. We found that women veterans told to have a mammogram by a health care professional were more than five times more likely to have ever had a mammogram (OR 5.41, CI 4.63-6.32) and nearly twice as likely to have had a mammogram within the past 2 years (OR 1.81, CI 1.57-2.09) as those who were not told to do so, controlling for age, race, VA user status, and length of military service. Regular VA users were more likely to have had a mammogram ever and within the past 2 years, controlling for other factors. Mammography use was not necessarily at a VA medical center. Interventions that promote better provider-patient communication and target older women veterans may have the most potential benefit. Whether VA health care is filling an important gap in access to mammography for older women veterans is an important policy question and warrants further research.

Abstract
OBJECTIVES The authors investigated whether utilization of six different cancer screening tests (mammography, clinical breast exam, Pap smear, Fecal Occult Blood Test, and Digital rectal exam) varied according to type of health care coverage. METHODS Data on the use of cancer screening tests and coverage in two age groups from a 1992 nationally representative cross-sectional survey of approximately 9,400 adults were analyzed. Multiple logistic regression analysis was used to estimate proportions of persons screened according to type and extent of coverage, adjusted for socioeconomic, demographic, and health status characteristics. RESULTS Persons aged 40 to 64 years with Medicaid coverage were equally as likely to receive five of six cancer screening tests as those with private fee-for-service coverage, and both groups were much more likely to be screened (70% higher for all six tests) than those who had no coverage. In contrast, persons aged 65 years and older who had supplemental private fee-for-service insurance in addition to Medicare were more likely to receive five of six tests than those with Medicare and Medicaid or those with Medicare only. For all six screening tests, managed care enrollees at all ages were approximately 10% more likely to be screened than persons enrolled in private fee-for-service plans. Fecal Occult Blood Test (25% versus 20%) and digital rectal exams (44% versus 38%) in persons aged 40 to 64 years and mammography (59% versus 48%) and Fecal Occult Blood Test screening (38% versus 30%) in the elderly were significantly more frequent for persons in managed care plans. CONCLUSIONS The extent of fee-for-service insurance coverage in the traditional indemnity US health care system was positively associated with the use of cancer screening tests. The authors found less difference in use of cancer screening between managed care and fee-for-service care in 1992 than we expected based on earlier research comparing use of preventive services in health maintenance organizations with fee-for-service care.

Abstract
Despite controversy about prostate cancer screening, administrative data show that the use of prostate specific antigen (PSA) testing in Canada has increased. This study sought to determine awareness and knowledge of prostate cancer and screening, use to date, and future intentions to have a digital rectal examination (DRE) and PSA test among Canadian men aged 40 and over. Data were collected through a Canada-wide cross-sectional random digit dial telephone survey of 629 men. Awareness of DRE and PSA, use to date, and future intended use varied with age and education. Although only 9% of respondents had had PSA testing for screening, future intentions to undergo this test were higher than use to date. Knowledge of prostate cancer and screening controversies was low, and men received more information about PSA from the media than from doctors. Men would, therefore, benefit from age- and education-specific information regarding the factors to consider in making an informed choice about prostate cancer screening.

Abstract
Physician counseling of patients on health related activities is an essential component of chronic disease prevention, however this requires patients to have ready access to health care providers. Previous studies have explored access to health care in terms of health plans and cost without accounting for the lack of preventive coverage inherent in many insurance policies. This study compares two measures of health care access, one using an assessment of cost and health plan availability, and a new coverage measure including preventive services. Data was collected from 2574 adult respondents to the 1991-92 Missouri Behavioral Risk Factor Surveillance System Surveys. Odds ratios were generated for demographic variables, health related behaviors and preventive screening and the two coverage measures. Using health plan and cost 22% lacked full coverage, however including availability of preventive coverage almost 60% lacked full coverage for preventive care. For both coverage measures significant associations were found with age, exercise, marital status, routine checkup and mammography screening. Using the measure of coverage of preventive services, rural residents and those who had never had cholesterol screening were more likely to lack coverage. Inclusion of preventive care in measures of health care coverage may alter previously reported associations with socio-demographic and health related factors. Policy makers should realize that including preventive services in health care coverage greatly increases the number of individuals lacking adequate coverage, and that those lacking adequate coverage are the least likely to undergo preventive screening.
