Factors associated with annual-interval mammography for women in their 40s

Design and pilot implementation of the Achieving Cancer Equity through Identification, Testing, and Screening (ACE-ITS) program in an urban underresourced population

INTRODUCTION

The Achieving Cancer Equity through Identification, Testing, and Screening (ACE-ITS) program is a community-engaged framework to improve mammography maintenance and rates of genetic risk assessment, counseling, and testing using a multilevel approach that enhances patient navigation through mobile health and community education.

METHODS

The ACE-ITS program is based on the National Institute of Minority Health and Health Disparities research framework focused on the individual (genetic testing, screening navigation) and community (community-based breast health education) levels and targeted to the biological- (genetic risk), behavioral- (mammography screening), sociocultural- (underserved Black and Hispanic women), and the health care system (patient navigation, automated text messages)-related domains. We further integrate the Practical Robust Implementation and Sustainability Model to describe our program implementation.

RESULTS

In collaboration with genetic counselors and community partners, we created educational modules on mammography maintenance and genetic counseling/testing that have been incorporated into the navigator-led community education sessions. We also implemented a universal genetic risk assessment tool and automated text message reminders for repeat mammograms into our mammography navigation workflow. Through the ACE-ITS program implementation, we have collaboratively conducted 22 educational sessions and navigated 585 women to mammography screening over the 2020-2021 calendar years. From January to December 2021, we have also conducted genetic risk assessment on 292 women, of whom 7 have received genetic counseling/testing.

CONCLUSIONS

We describe a multilevel, community-engaged quality improvement program designed to reduce screening-related disparities in Black and Hispanic women in our catchment area.

Factors Associated With Breast Cancer Screening Behaviors Among Women With Dense Breasts

OBJECTIVE

We sought to identify patient factors associated with patient-reported screening behaviors in women with dense breasts.

METHODS

An IRB-approved survey study of women with dense breasts presenting for annual screening mammography at an outpatient imaging center was previously conducted from March 2017 to February 2018. The survey included questions regarding mammographic screening frequency and recent participation in supplemental screening. These survey data were combined post hoc with clinical and demographic data and socioeconomic data imputed from census data. Logistic regression was used to identify patient factors associated with reported screening behaviors.

RESULTS

Surveys were completed by 508 women (median age, 59.0 years; range, 31.0-86.0 years) with dense breasts. Multivariable analysis demonstrated an independent association of undergoing mammographic screening annually with a history of discussing breast density with a doctor (adjusted odds ratio [AOR], 2.60; P = 0.019). Undergoing supplemental screening in the previous three years was independently associated with younger age (AOR, 1.59; P = 0.004), strong family history of breast cancer (AOR, 3.84; P = 0.027), higher perceived personal risk for breast cancer (AOR, 3.47; P = 0.004), and increased concern about radiation associated with screening examinations (AOR, 3.31; P = 0.006).

CONCLUSION

Women with dense breasts who had discussed breast density with a doctor were more likely to report undergoing annual screening mammography, while younger women and women with a strong family history of breast cancer, higher perceived personal risk for breast cancer, or greater concern about radiation were more likely to report recently undergoing supplemental screening.

Experiences of Women Who Refuse Recall for Further Investigation of Abnormal Screening Mammography: A Qualitative Study

Breast cancer has the highest incidence among all cancers for women in Taiwan. The current screening policy in Taiwan provides biennial mammogram tests for all women aged 45 to 69 years. A recommendation for further investigation is sent via post to women with a BI-RADS result of 0. The proportion of women who followed-up with a recall request for further investigation after an abnormal mammogram has been below 92.5% in recent years. Therefore, we aimed to explore the experiences of these women who refused recall for further investigation despite an abnormal mammogram. Purposive sampling was conducted on 13 women who refused recall for further examination of abnormal screening mammograms. Data collection included inductive, in-depth interviews or telephone interviews. A content analysis was applied. Three themes were identified: (1) negative screening experiences, (2) struggling with ’to go or not to go’, and (3) rationalizing without a follow-up examination. The first theme included three subthemes: (1) pain of examination, (2) the inconvenience of medical treatment; waiting, and (3) dissatisfaction with having to pay for further examination. The second major theme included three subthemes: (1) perceiving one’s susceptibility to breast cancer as very low, (2) questioning the accuracy of the results, and (3) procrastinating with a “head-in-the-sand” mentality. The third major theme included two subthemes: (1) fatalism and (2) paying attention to self-cultivation. In conclusion, the findings provide important information to healthcare providers involved in case management related to the actual living experiences of women with abnormal screening mammogram results and the additional education required to raise breast cancer awareness in the general public to achieve overall caring goals.

Breast cancer screening adherence rates and barriers of implementation in ethnic, cultural and religious minorities: A systematic review

Breast cancer is the most common cancer affecting women worldwide. Adherence to breast cancer screening guidelines is frequently lower in racial, ethnic and cultural minority populations and is affected by potential inequities or barriers to screening that these minorities face. Therefore, the aim of the present study was to collect information from different minority groups worldwide, assess adherence to breast cancer screening and evaluate barriers or limitations causing non-adherence, which should facilitate the development of effective interventions. A search was conducted through PubMed and Web of Science. Studies were considered as eligible if they met the following criteria: i) Female patients; ii) breast cancer screening program implemented in the country; iii) minority groups; iv) asymptomatic; v) report written in Portuguese or English; vi) study published from 2015 onwards. The Critical Appraisal Skills Programme checklist was used for qualitative studies and the Strengthening The Reporting of Observational Studies in Epidemiology checklist for cross-sectional studies. From the 348 initial articles, 86 were removed due to duplication and 19 were selected, analyzed and summarized, accordingly. Of the 19 studies included, 5.3% were classified as high quality, 52.6% as moderate to high and 42.1% as moderate. A total of 15 studies were cross-sectional and 4 were qualitative, collectively including 250,733 women. The rate of adherence to mammogram in different minorities was evaluated, obtaining a mean value of 49.7% in the last 2 years, and statistically significant barriers were selected and divided into sociodemographic; personal; ethnic, cultural and religious; and external factors. The characteristics of each population play a major role in the population's breast health practices. If the population, adherence rates, barriers and inequities are carefully studied, screening models may be customized and participation to breast cancer screening can be optimized, thereby reducing the high breast cancer-associated mortality.

Healthy lifestyle behaviors and the periodicity of mammography screening in Brazilian women

Introduction:

Certain behaviors have been associated with health promotion, including mammography screening, in women worldwide.

Objective:

The objective of this study was to determine whether there is an association between the periodicity of mammography screening and healthy lifestyle behaviors in Brazilian women employed at a public university in Bahia, Brazil.

Methods:

A total of 635 women of 50–69 years of age at the time of the interview, from the Brazilian Longitudinal Study of Adult Health cohort who were resident in Bahia, participated in the study. Data were collected using a multidimensional questionnaire that included questions on participants’ sociodemographic characteristics and health-related behaviors (smoking, alcohol consumption, leisure-time physical activity and diet) and another questionnaire that dealt with risk factors and breast cancer screening. Measures of association were calculated using simple and multivariate logistic regression.

Results:

The practice of physical activity, not smoking, moderate alcohol consumption and a healthy diet were the health behaviors most adopted by the women who had last had a mammogram ⩽2 years previously (which is in line with the interval recommended by the Brazilian Ministry of Health). A statistically significant association was found between a lapse of ⩾3 years since last undergoing mammography screening and excessive alcohol consumption, while a borderline association was found between the same screening interval and leisure-time physical inactivity.

Conclusion:

There was an association between lifestyle risk behaviors and a longer time interval between mammography screenings. The present results contribute to the debate on the use of mammography, lifestyle behaviors and health promotion among women.

Association of depression with adherence to breast cancer screening among women aged 50 to 74 years in the United States

RATIONALE, AIMS, AND OBJECTIVES

Previous research has shown inconsistent results regarding the association of depression and screening mammography use behaviours. This study aimed to assess the relationship between women's depression and mammography adherence.

METHODS

This cross-sectional study used data from the 2016 Behavioural Risk Factor Surveillance System and employed the Health Belief Model (HBM). The primary independent variable was the presence of depression. The dependent variable was adherence to biennial screening mammography based on the US Preventive Services Task Force guidelines. Demographic characteristics and HBM constructs were included as covariates. Univariate and multivariate logistic regressions were used.

RESULTS

A total of 139 550 women were included (weighted n = 48 712 531). Among them, 23.1% reported the presence of depression (n = 32 247). The unadjusted odds ratio (OR) for mammography use in women with depression was 0.85 (95% confidence interval [CI], 0.80-0.91, P < .001) compared with women without depression, and the probability of mammography use was significantly lower in women with depression (76.3%; 95% CI, 75.4-77.3) compared with women without depression (79.1%; 95% CI, 78.5-79.6). However, the adjusted OR was not statistically significant when controlling for demographic and HBM characteristics (1.02; 95% CI, 0.93-1.11, P = .698), and the probabilities of mammography use were similar between women with depression (80.1%; 95% CI, 79.0-81.3) and without depression (79.9%; 95% CI, 79.2-80.6).

CONCLUSIONS

Depression itself was related to nonadherence with mammography screening guidelines. However, after controlling for demographic and HBM characteristics, depression was not associated with adherence with mammography screening guidelines.

Factors associated with receipt of mammogram among caregivers: a comparison with non-caregivers

BACKGROUND

caregiving responsibilities significantly impact females' decisions on adhering to preventive mammography. The purpose of this study is to examine (1) the levels of mammogram receipt, (2) the role of caregiving factors on the receipt of mammogram in caregiving group, and (3) the role of cancer beliefs on mammogram screening in caregivers and non-caregivers.

METHODS

the 2017 Health Information National Trends Survey (HINTS) provides samples of 1228 women aged 40 to 75 years old for this secondary analysis. By using Andersen's Behavioral Model of Health Services Use, a binomial logistic regression model was used to analyze associations between mammography and socioeconomic factors, caregiving factors, and cancer belief factors.

RESULTS

caregivers who provided more caregiving hours per week (OR = 0.749, 95% CI = 0.564-0.94) and caregivers who had the belief of rather not knowing the likelihood of getting cancer (OR = 0.673, 95% CI = 0.496-0.914) were less likely to use mammogram. However, caregivers who believed cancer is more common than heart disease (OR = 1.490, 95% CI = 1.302-2.151) were more likely to use a mammogram. Non-caregivers who worried about getting cancer (OR = 1.158, 95% CI = 0.793-1.691) were more likely to use mammogram, but non-caregivers who had the belief of rather not know the likelihood of getting cancer (OR = 0.825, 95% CI = 0.713-0.955) were less likely to use mammogram.

CONCLUSIONS

to support caregivers' breast cancer prevention, caregiving-related policies based on caregiving hours should be developed. Particularly, effort to promote breast cancer screening education and care support among older primary caregivers will likely increase their adherence to preventive mammography uptake. The development of targeted cancer prevention interventions on specific cancer beliefs held by both groups are also urgently needed to promote mammography.

Monitoring and Developing a Volunteer Patient Navigation Intervention to Improve Mammography Compliance in a Safety Net Hospital

PURPOSE:

Although mammography screening is crucial for cancer detection, screening rates have been declining, particularly in patients of low socioeconomic status and minorities. We sought to evaluate and improve the compliance rates at our safety net hospital through a prospective randomized controlled trial of a volunteer-run patient navigation intervention.

METHODS:

Baseline 90-day institutional mammography compliance rates were evaluated for patients who received a physician order for screening mammograms over a 1-month period. This analysis aided in the creation of a prospective randomized controlled trial of a volunteer-run patient navigation intervention to improve compliance, with 49 total participants. The primary outcome was 14-day mammography compliance rates. Secondary analysis examined the efficacy of the intervention with respect to patient demographics, prior mammography compliance, family history of cancer, beliefs on mammography, and past medical history.

RESULTS:

Analysis of baseline institutional compliance revealed a 47.87% compliance rate, with the majority of compliance occurring within 14 days of order placement. The patient navigation intervention significantly improved compliance by 34% (42% in the control group, 76% in the intervention group). Additional findings included significantly improved compliance in patients who believed they had a low susceptibility to cancer, those who understood the benefits of mammography and early diagnosis, those who had a prior mammogram, those who were employed, and those with a family history of cancer.

CONCLUSION:

A system to monitor compliance and intervene using patient navigation significantly improved mammography compliance of patients in a safety net hospital. The relatively straightforward design of this volunteer-based intervention makes it affordable, easily replicable, and perhaps beneficial at other institutions.

Factors Associated with Adherence to Preventive Breast Cancer Screenings among Middle-aged African American Women

Medical and other health professionals recommend biyearly screening for breast cancer for women 40-74 years of age. However, the breast cancer screening rate of African American women aged 45 and up is lower than that of other ethnicities. The present study intended to identify factors impacting African American women's participation in breast cancer screening. This study is a longitudinal secondary data analysis of 3,911 African American participants of the Study of Women's Health Across the Nation. By using Systems Model of Clinical Preventive Care, multinomial logistic regression was applied to explore the likelihood of having breast cancer screenings (breast exam and/or mammogram) associating with predisposing factors, enabling factors, referencing factors, and situational factors. Participants with older age, with higher education, having a healthcare provider for female health, in far distance, and with a cancer(s) were significantly more likely to adhere to the recommendations of breast cancer screenings. However, participants who did not have time to visit doctors, did not trust the physicians, and who smoked regularly were significantly less likely to adhere to the recommendations of breast cancer screenings. Implications for policy and practice are discussed.

Experiences and perceptions about undergoing mammographic screening: a qualitative study involving women from a county in Sweden

PURPOSE

 An organized population-based mammographic screening programme aims for an early detection of potential breast abnormalities so that treatment can commence. Continuous participation and a high attendance rate are vital for an effective programme. It is important to understand the underlying reasons for participation in mammographic screening, should there be factors that are amendable within reason and could be adjusted. Therefore, the invited women are valuable sources of information. This study aimed at describing the experiences and perceptions about mammographic screening of women from three municipalities in a Swedish county.

METHOD

 Six semi-structured focus-group discussions, each with four to five participants, were held. Content analysis was then conducted.

RESULTS

 The screening procedure, such as staff professionalism, was covered. Other people's opinions and the woman's own understanding affected the women's decisions on whether or not to undergo the procedure. Structural conditions, such as travel time and financial issues, were sources of concern. However, the offer to perform mammographic screening was perceived with gratitude.

CONCLUSIONS

 Structural conditions, risk and time perceptions, the screening procedure, attitudes towards undergoing it and appreciation of its benefit may influence the women's continuous willingness to be screened, which in turn may affect public and individual health.

Prevalence of and factors associated with mammography and prostate-specific antigen screening among World Trade Center Health Registry enrollees, 2015-2016

To compare the prevalence of mammography and prostate-specific antigen (PSA) testing in 9/11-exposed persons with the prevalence among the US population, and examine the association between 9/11 exposures and these screening tests using data from the World Trade Center Health Registry (WTCHR) cohort. We studied 8190 female and 13,440 male enrollees aged ≥40 years at survey completion (2015–2016), who had a medical visit during the preceding year, had no self-reported breast or prostate cancer, and did not have screening for non-routine purposes. We computed age-specific prevalence of mammography (among women) and PSA testing (among men), and compared to the general population using 2015 National Health Interview Survey data (NHIS). We also computed the adjusted prevalence ratio (PR) and 95% confidence interval (95% CI) to examine the relationship between 9/11 exposures and screening uptakes using modified Poisson regression. Our enrollees had higher prevalences of mammogram and PSA testing than the US general population. 9/11 exposure was not associated with mammography uptake. Proximity to the WTC at the time of the attacks was associated with PSA testing in the age 60–74 group (PR = 1.06; 95% CI = 1.00–1.12). Among rescue/recovery workers and volunteers (RRW), being a firefighter was associated with higher PSA testing than other RRW across all age groups (40–49: PR = 1.45, 95% CI 1.16–1.81; 50–59: PR = 1.33, 95% CI 1.22–1.44; 60–74: PR = 1.14, 95% CI 1.06–1.23). Screening activities should be considered when studying cancer incidence and mortality in 9/11 exposed populations.

•

Prevalence of breast and prostate cancer screening was higher than the U.S. population.

•

World Trade Center exposure was not associated with breast cancer screening.

•

Firefighters had higher PSA testing than other type of rescue and recovery workers.

Routine colonoscopy, diabetic eye care, mammogram and pap smear screening in vascular surgery patients

Objective An increasing emphasis on preventive medicine has been supported by the recent reforms in United States health care system. Majority of the patients seen in vascular surgery clinics are elderly with more extensive medical comorbidities compared to the general population. Thus, these patients would be expected at higher risk for common malignant pathologies such as colon, breast and cervical cancer, and nonmalignant diseases such as diabetic retinopathy. This study looked at the screening compliance of vascular patients compared to data provided by Centers for Disease Control on the national and state levels. Methods The office records of 851 consecutive patients seen in Brooklyn and Staten Island vascular clinics were examined. We queried patients regarding their last colonoscopy, diabetic eye exams, recent mammograms, and Pap smears. Our patient screening compliance was compared between the two clinics as well as to the national and New York state data provided by Centers for Disease Control. Compliance with regard to patient's age was also examined. Results Patients referred to the Staten Island office have a better colonoscopy compliance compared to the Brooklyn office ( P = .0001) and the national Centers for Disease Control average ( P = .026). Compliance for mammography and cervical cancer screening was higher in Staten Island office compared to the Brooklyn office ( P = .0001, P < .0001), respectively. Compliance was lower for Pap smear ( P = .0273) in Brooklyn when compared to the national average. Compliance for colonoscopy increased with age for both clinics ( P = .001, P < .001), while Pap smear decreased ( P < .001, P = .004). Conclusion Patients in vascular clinics in an urban setting had better adherence to screening protocol than the national and state average, with the exception of female patients for colonoscopy in our Brooklyn vascular office. There exists variability in both patient populations based on sub-specific locality and demographics including socioeconomic status. Overall, however patients in Staten Island had better compliance and adherence to the screening protocol than Brooklyn vascular clinic.

Cultural Beliefs and Attitudes About Breast Cancer and Screening Practices Among Arabic Women in Australia

BACKGROUND

Arabic women have been consistently reported as having remarkably low participation rates in breast cancer screening measures in their home countries and after migration to Western countries. Little is known about the screening behaviors of Arabic women in Australia.

OBJECTIVES

This study aimed to report breast cancer screening practices among Arabic women in Australia and to examine the relationship between (1) demographic factors and (2) the Arabic version of the Breast Cancer Screening Beliefs Questionnaire (BCSBQ) score and women's breast screening behaviors.

METHODS

A descriptive cross-sectional method was used. Both English and Arabic versions of the BCSBQ were administered to the 251 Arabic Australian women 18 years or older who participated in the study.

RESULTS

The majority of participants (62.9%-92%) had heard of breast awareness, clinical breast examination, and mammography. However, only 7.6% practiced breast awareness monthly, 21.4% had undergone clinical breast examination annually, and 40.3% had biannual mammography. Length of stay in Australia, being retired, and being unemployed were positively associated with the recommended performance of breast awareness and mammography. In terms of BCSBQ scores, women who engaged in the 3 screening practices had significantly higher scores on the attitudes to health check-ups and barriers to mammography subscales.

CONCLUSION

Attitudes toward health check-ups and perceived barriers to mammography were important determinants of breast cancer screening practices among Arabic Australian women.

IMPLICATIONS FOR PRACTICE

To fully understand barriers discouraging Arabic Australian women from participating in breast cancer screening practices, efforts should be focused on specific subgroup (ie, working group) of Arabic Australian women.

Patient Knowledge of and Barriers to Breast, Colon, and Cervical Cancer Screenings: A Cross-Sectional Survey of TRICARE Beneficiaries

TRICARE Prime beneficiaries view cancer screening as important for overall health but may need more frequent scheduling reminders, education, and scheduling options to increase below-average screening rates.

Automated telephone communication systems for preventive healthcare and management of long-term conditions

BACKGROUND

Automated telephone communication systems (ATCS) can deliver voice messages and collect health-related information from patients using either their telephone's touch-tone keypad or voice recognition software. ATCS can supplement or replace telephone contact between health professionals and patients. There are four different types of ATCS: unidirectional (one-way, non-interactive voice communication), interactive voice response (IVR) systems, ATCS with additional functions such as access to an expert to request advice (ATCS Plus) and multimodal ATCS, where the calls are delivered as part of a multicomponent intervention.

OBJECTIVES

To assess the effects of ATCS for preventing disease and managing long-term conditions on behavioural change, clinical, process, cognitive, patient-centred and adverse outcomes.

SEARCH METHODS

We searched 10 electronic databases (the Cochrane Central Register of Controlled Trials; MEDLINE; Embase; PsycINFO; CINAHL; Global Health; WHOLIS; LILACS; Web of Science; and ASSIA); three grey literature sources (Dissertation Abstracts, Index to Theses, Australasian Digital Theses); and two trial registries (www.controlled-trials.com; www.clinicaltrials.gov) for papers published between 1980 and June 2015.

SELECTION CRITERIA

Randomised, cluster- and quasi-randomised trials, interrupted time series and controlled before-and-after studies comparing ATCS interventions, with any control or another ATCS type were eligible for inclusion. Studies in all settings, for all consumers/carers, in any preventive healthcare or long term condition management role were eligible.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods to select and extract data and to appraise eligible studies.

MAIN RESULTS

We included 132 trials (N = 4,669,689). Studies spanned across several clinical areas, assessing many comparisons based on evaluation of different ATCS types and variable comparison groups. Forty-one studies evaluated ATCS for delivering preventive healthcare, 84 for managing long-term conditions, and seven studies for appointment reminders. We downgraded our certainty in the evidence primarily because of the risk of bias for many outcomes. We judged the risk of bias arising from allocation processes to be low for just over half the studies and unclear for the remainder. We considered most studies to be at unclear risk of performance or detection bias due to blinding, while only 16% of studies were at low risk. We generally judged the risk of bias due to missing data and selective outcome reporting to be unclear.For preventive healthcare, ATCS (ATCS Plus, IVR, unidirectional) probably increase immunisation uptake in children (risk ratio (RR) 1.25, 95% confidence interval (CI) 1.18 to 1.32; 5 studies, N = 10,454; moderate certainty) and to a lesser extent in adolescents (RR 1.06, 95% CI 1.02 to 1.11; 2 studies, N = 5725; moderate certainty). The effects of ATCS in adults are unclear (RR 2.18, 95% CI 0.53 to 9.02; 2 studies, N = 1743; very low certainty).For screening, multimodal ATCS increase uptake of screening for breast cancer (RR 2.17, 95% CI 1.55 to 3.04; 2 studies, N = 462; high certainty) and colorectal cancer (CRC) (RR 2.19, 95% CI 1.88 to 2.55; 3 studies, N = 1013; high certainty) versus usual care. It may also increase osteoporosis screening. ATCS Plus interventions probably slightly increase cervical cancer screening (moderate certainty), but effects on osteoporosis screening are uncertain. IVR systems probably increase CRC screening at 6 months (RR 1.36, 95% CI 1.25 to 1.48; 2 studies, N = 16,915; moderate certainty) but not at 9 to 12 months, with probably little or no effect of IVR (RR 1.05, 95% CI 0.99, 1.11; 2 studies, 2599 participants; moderate certainty) or unidirectional ATCS on breast cancer screening.Appointment reminders delivered through IVR or unidirectional ATCS may improve attendance rates compared with no calls (low certainty). For long-term management, medication or laboratory test adherence provided the most general evidence across conditions (25 studies, data not combined). Multimodal ATCS versus usual care showed conflicting effects (positive and uncertain) on medication adherence. ATCS Plus probably slightly (versus control; moderate certainty) or probably (versus usual care; moderate certainty) improves medication adherence but may have little effect on adherence to tests (versus control). IVR probably slightly improves medication adherence versus control (moderate certainty). Compared with usual care, IVR probably improves test adherence and slightly increases medication adherence up to six months but has little or no effect at longer time points (moderate certainty). Unidirectional ATCS, compared with control, may have little effect or slightly improve medication adherence (low certainty). The evidence suggested little or no consistent effect of any ATCS type on clinical outcomes (blood pressure control, blood lipids, asthma control, therapeutic coverage) related to adherence, but only a small number of studies contributed clinical outcome data.The above results focus on areas with the most general findings across conditions. In condition-specific areas, the effects of ATCS varied, including by the type of ATCS intervention in use.Multimodal ATCS probably decrease both cancer pain and chronic pain as well as depression (moderate certainty), but other ATCS types were less effective. Depending on the type of intervention, ATCS may have small effects on outcomes for physical activity, weight management, alcohol consumption, and diabetes mellitus. ATCS have little or no effect on outcomes related to heart failure, hypertension, mental health or smoking cessation, and there is insufficient evidence to determine their effects for preventing alcohol/substance misuse or managing illicit drug addiction, asthma, chronic obstructive pulmonary disease, HIV/AIDS, hypercholesterolaemia, obstructive sleep apnoea, spinal cord dysfunction or psychological stress in carers.Only four trials (3%) reported adverse events, and it was unclear whether these were related to the interventions.

AUTHORS' CONCLUSIONS

ATCS interventions can change patients' health behaviours, improve clinical outcomes and increase healthcare uptake with positive effects in several important areas including immunisation, screening, appointment attendance, and adherence to medications or tests. The decision to integrate ATCS interventions in routine healthcare delivery should reflect variations in the certainty of the evidence available and the size of effects across different conditions, together with the varied nature of ATCS interventions assessed. Future research should investigate both the content of ATCS interventions and the mode of delivery; users' experiences, particularly with regard to acceptability; and clarify which ATCS types are most effective and cost-effective.

Validation of an Efficient Screening Tool to Identify Low-Income Women at High Risk for Hereditary Breast Cancer

BACKGROUND/AIMS

We compared the 6-Point Scale, a screening tool to identify low-income women for referral to genetic counseling, with genetic counselors' (GCs') recommendation and the Referral Screening Tool (RST).

METHODS

RST and 6-Point Scale scores were computed for 2 samples: (1) S1, public hospital mammography clinic patients in 2006-2010 (n = 744), classified by GCs as high risk (meriting referral to counseling) or not high risk, and (2) S2, primary care patients enrolled in an education intervention study in 2011-2012 (n = 1,425). Sensitivity, specificity, and area under the ROC curve (AUROC) were computed for the 6-Point Scale score versus GC and RST classification as high risk.

RESULTS

The 6-Point Scale had low sensitivity (0.27, 95% confidence interval [CI] 0.21-0.34) but high specificity (0.97, 95% CI 0.95-0.99) and AUROC (0.85, 95% CI 0.81-0.90) versus GC classification, and high sensitivity (S1: 0.90, 95% CI 0.79-1.00; S2: 0.94, 95% CI 0.87-0.97), specificity (S1: 0.95, 95% CI 0.93-0.97; S2: 0.94, 95% CI 0.93-0.96), and AUROC (S1: 0.98, 95% CI 0.96-0.99; S2: 0.98, 95% CI 0.98-0.99) versus the RST.

CONCLUSION

The 6-Point Scale compared favorably with the RST, a validated instrument, and is potentially useful as a simple tool for administration in a safety net setting, requiring minimal time investment by primary care physicians and their staff and no financial investment in tablet computers or software.

Predictors of Participation in Mammography Screening among Non-Hispanic Black, Non-Hispanic White, and Hispanic Women

INTRODUCTION

Many factors influence women's decisions to participate in guideline-recommended screening mammography. We evaluated the influence of women's socioeconomic characteristics, health-care access, and cultural and psychological health-care preferences on timely mammography screening participation.

MATERIALS AND METHODS

A random digit dial survey of United States non-Hispanic Black, non-Hispanic White, and Hispanic women aged 40-75, from January to August 2009, determined self-reported time of most recent mammogram. Screening rates were assessed based on receipt of a screening mammogram within the prior 12 months, the interval recommended at the time by the American Cancer Society.

RESULTS

Thirty-nine percent of women reported not having a mammogram within the last 12 months. The odds of not having had a screening mammography were higher for non-Hispanic White women than for non-Hispanic Black (OR = 2.16, 95% CI = 0.26, 0.82, p = 0.009) or Hispanic (OR = 4.17, 95% CI = 0.12, 0.48, p = 0.01) women. Lack of health insurance (OR = 3.22, 95% CI = 1.54, 6.73, p = 0.002) and lack of usual source of medical care (OR = 3.37, 95% CI = 1.43, 7.94, p = 0.01) were associated with not being screened as were lower self-efficacy to obtain screening (OR = 2.43, 95% CI = 1.26, 4.73, p = 0.01) and greater levels of religiosity and spirituality (OR = 1.42, 95% CI = 1.00, 2.00, p = 0.05). Neither perceived risk nor present temporal orientation was significant.

DISCUSSION

Odds of not having a mammogram increased if women were uninsured, without medical care, non-Hispanic White, older in age, not confident in their ability to obtain screening, or held passive or external religious/spiritual values. Results are encouraging given racial disparities in health-care participation and suggest that efforts to increase screening among minority women may be working.

Women with abnormal screening mammography lost to follow-up: An experience from Taiwan

Breast cancer has the highest incidence among all cancers for women in Taiwan. The current screening policy in Taiwan suggested a biennial mammography for all women 40 to 69 years of age. A recommendation for additional testing is recommended for women with a BI-RADS result of 0 or 4; a request made via postal mail. Approximately 20% of high-risk patients do not receive additional follow-up. Therefore, we aimed to explore the causes of these patients being lost to follow-up, despite an abnormal mammogram. Two questionnaires were designed separately according to the conceptual framework of the Health Belief Model. Study participants, women who received a screening mammography at the National Taiwan University Hospital in 2011 with a BI-RAD of 0 or 4, were interviewed via telephone. The dependent variable was receipt of follow-up or not. The analyses were performed by using χ tests and logistic regression models. In total, 528 women were enrolled in the study: 51.2% in BI-RADS 0 group and 56.6% in BI-RADS 4, respectively. In the BI-RADS 0 group, those patients who received a follow-up examination cited the most likely causes to be physician suggestion, health implications, and concerns regarding breast cancer. Patients who did not receive a follow-up examination cited a lack of time and a perception of good personal health as primary reasons. In the BI-RADS 4 group, those patients who received a follow-up examination cited the physician's recommendation and a recognition of the importance of follow-up examinations. Patients who did not receive a follow-up examination cited having received follow-up at another hospital and a desire for a second opinion. In the BI-RADS 0 group, multivariate analysis showed that patients with higher scores in the "perceived benefits" domain were statistically more likely to receive a follow-up examination. There was no significant difference in perceived threats, perceived barriers, action cues, or self-efficacy between groups. We conclude that additional education to raise breast cancer awareness in the general public and healthcare providers will be needed to improve the rate of follow-up examinations after an abnormal screening mammogram.

Cancer Screening Patterns and Concerns in Caregivers of Patients Undergoing Radiation Therapy

PURPOSE

Evolving cancer screening guidelines can confuse the public. Caregivers of patients undergoing radiation oncology may represent a promising outreach target for disseminating and clarifying screening information. We aimed to: (1) determine the incidence of cancer screening in this cohort, and (2) identify barriers to and deficiencies in screening.

METHODS

We distributed a 21-item survey on cancer screening history and related concerns to caregivers ≥ 18 years old at one urban and two suburban radiation oncology centers. Reported screening habits were compared with American Cancer Society/American Urological Association guidelines for breast, cervical, colon, and prostate cancer. Statistical analysis included Pearson χ(2) tests.

RESULTS

A total of 209 caregivers (median age, 55.5 years; 146 women) were surveyed. Although 92% had primary care physicians (PCPs), only 58% reported being informed about recommended screening intervals. Participants ≤ 49 years old were less likely to report PCP discussion of cancer screening than older participants (41% and 66%, respectively; P = .006). Ninety-eight respondents (47%) had one or more screening concern(s). Among screening-eligible caregivers, 23 (18%) reported not undergoing regular colonoscopies. Fourteen women (13%) did not have Papanicolaou smears at recommended intervals, and 21 (18%) did not have annual mammograms. Six men (21%) did not undergo annual prostate screening. Decreased recommended screening with colonoscopy and mammography correlated with younger age.

CONCLUSION

This survey of relatively unexplored caregivers identified cancer screening deficiencies and concerns that might be addressed by targeted interventions. With approximately 60% of patients with cancer receiving radiation therapy, advice in the radiation oncology setting could positively affect cancer screening behaviors in caregivers.

The relationship of social support concept and repeat mammography among Iranian women

BACKGROUND

Breast cancer ranks as the first most common cancer among the Iranian women. The regular repeat of mammography with 1-2 year intervals leads to the increased efficiency of early detection of breast cancer. The present study examined the predictors of repeat mammography. It was hypothesized that higher social support is connected with mammography repeat.

METHODS

A cross-sectional study was carried out among 400 women 50 years and older in Sanandaj, Iran. Data was collected by the questionnaire including information on socio demographical variables and measuring social support level. Data was analyzed by SPSS16 software. Multiple logistic regression was used to determine the predictive power of demographic variables and dimensions of social support for repeat mammography.

RESULTS

Women aged 50-55 years had three times odds of repeat mammography compared to women aged 56-60 years) OR, 3.02). Married women had greater odds of repeat mammography compared to single women (P < 0.006). The probability of repeat mammography in women with higher social support was 0.93 times greater than the women with lower social support (OR, 0.93; 95 % CI, 0.91-0.95; P < 0.0001).

CONCLUSIONS

Iranian women are less likely repeat mammography than other Asian women. Identifying the associations between perceived social support and repeat mammography may offer detailed information to allow for future study and guide the development of interventions not only for Iranian women but also for similar cultural that received pay too little attention to date in the breast cancer literature.

Knowledge about mammography and associated factors: population surveys with female adults and elderly

The purpose of this paper is to describe the knowledge about mammography and to identify associated factors in female adults and elderly. Data were obtained from two population surveys, one with female adults and another with elderly women from Florianópolis (SC) in 2009 - 2010. A descriptive analysis of the variables was carried out, the appropriate mean of responses about mammography was estimated and crude and adjusted Poisson regression was conducted to identify associated factors. Among adults, 23.1% answered all of the questions appropriately and the appropriate average responses was 7.2 (95%CI 7.1 - 7.3) in a total of 9. In the adjusted model, older age, higher education and income were associated with knowledge about mammography. For the elderly, 15.3% answered all questions appropriately and the average of appropriate responses was 6.4 (95%CI 5.2 - 6.5) and the factors associated with knowledge about mammography in the adjusted model were younger age groups, increased education and income, and identification of mammography as the main diagnostic method for breast cancer. Information about mammography can neither be transmitted in a clear way nor be easily understood; there are also demographic and socioeconomic differences concerning the knowledge about the exam.

Women's responses to changes in U.S. Preventive Task Force's mammography screening guidelines: results of focus groups with ethnically diverse women

BACKGROUND

The 2009 U.S. Preventive Services Task Force (USPSTF) changed mammography guidelines to recommend routine biennial screening starting at age 50. This study describes women's awareness of, attitudes toward, and intention to comply with these new guidelines.

METHODS

Women ages 40-50 years old were recruited from the Boston area to participate in focus groups (k = 8; n = 77). Groups were segmented by race/ethnicity (Caucasian = 39%; African American = 35%; Latina = 26%), audio-taped, and transcribed. Thematic content analysis was used.

RESULTS

Participants were largely unaware of the revised guidelines and suspicious that it was a cost-savings measure by insurers and/or providers. Most did not intend to comply with the change, viewing screening as obligatory. Few felt prepared to participate in shared decision-making or advocate for their preferences with respect to screening.

CONCLUSIONS

Communication about the rationale for mammography guideline changes has left many women unconvinced about potential disadvantages or limitations of screening. Since further guideline changes are likely to occur with advances in technology and science, it is important to help women become informed consumers of health information and active participants in shared decision-making with providers. Additional research is needed to determine the impact of the USPSTF change on women's screening behaviors and on breast cancer outcomes.

Adherence to cancer screening guidelines and predictors of improvement among participants in the Kansas State Employee Wellness Program

Introduction

Employee wellness programs (EWPs) have been used to implement worksite-based cancer prevention and control interventions. However, little is known about whether these programs result in improved adherence to cancer screening guidelines or how participants’ characteristics affect subsequent screening. This study was conducted to describe cancer screening behaviors among participants in a state EWP and identify factors associated with screening adherence among those who were initially nonadherent.

Methods

We identified employees and their dependents who completed health risk assessments (HRAs) as part of the Kansas state EWP in both 2008 and 2009. We examined baseline rates of adherence to cancer screening guidelines in 2008 and factors associated with adherence in 2009 among participants who were initially nonadherent.

Results

Of 53,095 eligible participants, 13,222 (25%) participated in the EWP in 2008 and 6,205 (12%) participated in both years. Among the multiyear participants, adherence was high at baseline to screening for breast (92.5%), cervical (91.8%), and colorectal cancer (72.7%). Of participants who were initially nonadherent in 2008, 52.4%, 41.3%, and 33.5%, respectively, became adherent in the following year to breast, cervical, and colorectal cancer screening. Suburban/urban residence and more frequent doctor visits predicted adherence to breast and colorectal cancer screening guidelines.

Conclusion

The effectiveness of EWPs for increasing cancer screening is limited by low HRA participation rates, high rates of adherence to screening at baseline, and failure of nonadherent participants to get screening. Improving overall adherence to cancer screening guidelines among employees will require efforts to increase HRA participation, stronger interventions for nonadherent participants, and better access to screening for rural employees.

Association between cancer screening behavior and family history among Japanese women

OBJECTIVE

To examine lifestyle habits and cancer screening behavior in relation to a family history of cancer among Japanese women.

METHODS

A cross-sectional study was conducted based on baseline data from the Japan Nurses' Health Study collected from June 2001 to March 2007. Participants were 47,347 female nurses aged 30-59 years residing in 47 prefectures in Japan. We compared lifestyle habits and the utilization of cancer screenings (cervical and breast) between women with and without a family history of the relevant cancer.

RESULTS

Although there were no differences in lifestyle habits with the exception of smoking status, women with a family history of uterine cancer were more likely to have undergone cervical cancer screenings (p<0.01). Women with a family history of breast cancer were also more likely to have undergone breast cancer screenings regardless of their age (p<0.01), but lifestyle behaviors did not differ. Among women with a family history of uterine cancer, those with a sister history were more likely to have undergone not only cervical (OR, 1.89; 95% CIs, 1.39-2.58), but also breast cancer screenings (OR, 1.54; 95% CIs 1.13-2.09).

CONCLUSION

Having a family history of cancer was associated with cancer screening behavior, but not health promotive behaviors.

Higher-status occupations and breast cancer: a life-course stress approach

Using the 1957-2011 data from 3682 White non-Hispanic women (297 incident breast cancer cases) in the Wisconsin Longitudinal Study, United States, we explore the effect of occupation in 1975 (at age 36) on breast cancer incidence up to age 72. Our study is motivated by the paradoxical association between higher-status occupations and elevated breast cancer risk, which presents a challenge to the consistent health advantage of higher social class. We found that women in professional occupations had 72122% and women in managerial occupations had 57-89% higher risk of a breast cancer diagnosis than housewives and women in lower-status occupations. We explored an estrogen-related pathway (reproductive history, health behaviors, and life-course estrogen cycle) as well as a social stress pathway (occupational experiences) as potential explanations for the effect of higher-status occupations. The elevated risk of breast cancer among professional women was partly explained by estrogen-related variables but remained large and statistically significant. The association between managerial occupations and breast cancer incidence was fully explained by job authority defined as control over others' work. Exercising job authority was related to higher breast cancer risk (HR = 1.57, 95% CI: 1.12, 2.18), especially with longer duration of holding the professional/managerial job. We suggest that the assertion of job authority by women in the 1970s involved stressful interpersonal experiences that may have promoted breast cancer development via prolonged dysregulation of the glucocorticoid system and exposure of the breast tissue to adverse effects of chronically elevated cortisol. Our study emphasizes complex biosocial pathways through which women's gendered occupational experiences become embodied and drive forward physiological repercussions.

Dampening enthusiasm for circulating microRNA in breast cancer

Genome-wide platforms for high-throughput profiling of circulating miRNA (oligoarray or miR-Seq) offer enormous promise for agnostic discovery of circulating miRNA biomarkers as a pathway for development in breast cancer detection. By harmonizing data from 15 previous reports, we found widespread inconsistencies across prior studies. Whether this arises from differences in study design, such as sample source or profiling platform, is unclear. As a reproducibility experiment, we generated a genome-wide plasma miRNA dataset using the Illumina oligoarray and compared this to a publically available dataset generated using an identical sample size, substrate and profiling platform. Samples from 20 breast cancer patients, 20 mammography-screened controls, as well as 20 breast cancer patients after surgical resection and 10 female lung or colorectal cancer patients were included. After filtering for miRNAs derived from blood cells, and for low abundance miRNAs (non-detectable in over 10% of samples), a set of 522 plasma miRNAs remained, of which 46 were found to be differentially expressed between breast cancer patients and healthy controls (p<0.05), of which only 3 normalized to baseline levels in post-resection cases and were unique to breast cancer vs. lung or colorectal cancer (miR-708*, miR-92b* and miR-568, none previously reported). We were unable to demonstrate reproducibility by various measures between the two datasets. This finding, along with widespread inconsistencies across prior studies, highlight the need for better understanding of factors influencing circulating miRNA levels as prerequisites to progress in this area of translational research.

Barriers to screening mammography

Breast cancer (BRCA) is the second most commonly diagnosed cancer among women in the USA, and mammography is an effective means for the early detection of BRCA. Identifying the barriers to screening mammography can inform research, policy and practice aiming to increase mammography adherence. A literature review was conducted to determine common barriers to screening mammography adherence. PsycINFO and PubMed databases were searched to identify studies published between 2000 and 2012 that examined barriers associated with reduced mammography adherence. Three thematic groups of barriers, based on social ecology, were identified from the literature: healthcare system-level, social and individual-level barriers. Researchers must consider screening behaviour in context and, therefore, should simultaneously consider each level of barriers when attempting to understand screening behaviour and create interventions to increase mammography adherence.

Relationship between colorectal cancer screening adherence and knowledge among vulnerable rural residents of Appalachian Kentucky

BACKGROUND

Colorectal cancer (CRC) is 1 of the leading causes of cancer-related deaths among residents of rural Appalachia. Rates of guideline-consistent CRC screening in Appalachian Kentucky are suboptimal.

OBJECTIVE

This study sought to determine the relationship between CRC screening knowledge, specifically regarding recommended screening intervals, and receipt of screening among residents of rural Appalachian Kentucky.

METHODS

Residents of Appalachian Kentucky (n = 1096) between the ages of 50 and 76 years completed a telephone survey including questions on demographics, health history, and knowledge about CRC screening between November 20, 2009, and April 22, 2010.

RESULTS

Although 67% of respondents indicated receiving screenings according to guidelines, respondents also demonstrated significant knowledge deficiencies about screening recommendations. Nearly half of respondents were unable to identify the recommended screening frequency for any of the CRC screening modalities. Accuracy about the recommended frequency of screening was positively associated with screening adherence.

CONCLUSIONS

Enhanced educational approaches have the potential to increase CRC screening adherence in this population and reduce cancer mortality in this underserved region.

IMPLICATIONS FOR PRACTICE

Nurses play a critical role in patient education, which ultimately may increase screening rates. To fulfill this role, nurses should incorporate current recommendation about CRC screening into educational sessions. Advanced practices nurses in rural settings should also be aware of the increased vulnerability of their patient population and develop strategies to enhance awareness about CRC and the accompanying screening tests.

Declining mammography screening in a state Medicaid Fee-for-Service program: 1999-2008

OBJECTIVE

To evaluate and compare annual and biennial mammography screening rates across age, race, and geographic location (rural-urban) and to determine mammography screening persistence over 10 years among women enrolled in the West Virginia (WV) Medicaid Fee-for-Service (FFS) program.

METHODS

The WV Medicaid FFS administrative claims data for women recipients aged 40-64 from 1999 to 2008 were used for study purposes. Annual and biennial screening rates and persistence with screening were determined for women who were continuously enrolled in the WV Medicaid FFS program for respective calendar years.

RESULTS

A steady decline in the annual and biennial screening rates over a 10-year period (1999-2008) was observed among women recipients aged 40-64 years in the WV Medicaid FFS program, and screening persistence was also lower. Both annual and biennial screening rates and persistence varied by different demographic characteristics.

CONCLUSIONS

Although mammography screening services are covered under Medicaid programs, underuse persists as a major concern. The results of this study emphasize the need to identify and address barriers to mammography screening in low-income rural populations.

The demographic, system, and psychosocial origins of mammographic screening disparities: prediction of initiation versus maintenance screening among immigrant and non-immigrant women

Disparities in breast screening are well documented. Less clear are differences within groups of immigrant and non-immigrant minority women or differences in adherence to mammography guidelines over time. A sample of 1,364 immigrant and non-immigrant women (African American, English Caribbean, Haitian, Dominican, Eastern European, and European American) were recruited using a stratified cluster-sampling plan. In addition to measuring established predictors of screening, women reported mammography frequency in the last 10 years and were (per ACS guidelines at the time) categorized as never, sub-optimal (<1 screen/year), or adherent (1+ screens/year) screeners. Multinomial logistic regression showed that while ethnicity infrequently predicted the never versus sub-optimal comparison, English Caribbean, Haitian, and Eastern European women were less likely to screen systematically over time. Demographics did not predict the never versus sub-optimal distinction; only regular physician, annual exam, physician recommendation, and cancer worry showed effects. However, the adherent categorization was predicted by demographics, was less likely among women without insurance, a regular physician, or an annual exam, and more likely among women reporting certain patterns of emotion (low embarrassment and greater worry). Because regular screening is crucial to breast health, there is a clear need to consider patterns of screening among immigrant and non-immigrant women as well as whether the variables predicting the initiation of screening are distinct from those predicting systematic screening over time.

It's the amount of thought that counts: when ambivalence contributes to mammography screening delay

PURPOSE

This study examines whether ambivalence toward mammography screening, as moderated by total amount of thought given to the reasons for and against getting mammograms at recommended intervals, predicts greater delay in obtaining subsequent screening mammograms.

METHODS

A sample of 3,430 insured women with recent (within the last 8-9 months) screening mammograms completed telephone interviews as part of a 5-year intervention study to achieve sustained adherence to annual-interval mammography. Delay was assessed by the number of days between mammograms.

RESULTS

Controlling for demographic factors and perceived screening barriers, days between mammograms increased as ambivalence and thought increased. Thought moderated ambivalence: Among women who were most ambivalent, women obtained mammograms 1 month earlier for each unit increase in thought.

CONCLUSION

Future studies should test innovative ways to resolve ambivalence and increase thought about consequences of getting mammograms as a strategy to promote mammography screening adherence.

Telephone counseling and attendance in a national mammography-screening program a randomized controlled trial

BACKGROUND

In Germany, a mammography-screening program (MSP) was implemented on a national level. It complies with all criteria of the European guidelines for quality assurance in screening mammography; however, the attendance rate is 54%, falling short of the target attendance rate of 70%. The aim of this study was to investigate whether additional telephone counseling improves attendance among nonresponders and the level of satisfaction with telephone counseling.

DESIGN

In a prospective RCT, women identified as nonresponders in the MSP were randomized to a control group that received written reminders or to an intervention group that additionally received telephone counseling. In a follow-up, a subset of the intervention group was contacted by telephone regarding their satisfaction with telephone counseling.

SETTING/PARTICIPANTS

In 2008, a total of 5477 women aged 50-69 years who were eligible for the German MSP but had not participated up to 6 weeks after the first invitation were included in the study.

INTERVENTIONS

Individual telephone counseling consisted of scripted calls from a trained counselor who provided information on MSP and answered the woman's questions.

MAIN OUTCOME MEASURES

Report of mammography use provided by the screening unit 3 months after the reminder was sent.

RESULTS

Analysis was conducted in 2009. Comparison of screening attendance revealed a significantly higher attendance rate in the intervention group compared with controls (29.7% vs 26.1%, p=0.0035). When only women for whom telephone numbers were available were analyzed, attendance was even better (35.5% vs 29.7%, p=0.0004). In the follow-up, 278 of 404 women were actually surveyed. Of those, 33% stated that telephone counseling had influenced their decision, 56% stated that they had undergone screening mammography, and 77% agreed that personal telephone counseling should be used routinely to encourage nonresponders to go for screening.

CONCLUSIONS

Individual telephone counseling for nonresponders to a national program for breast cancer screening was well accepted by participants and effective.

TRIAL REGISTRATION

This study is registered at the Australian New Zealand Clinical Trials Registry ACTRN12611000645954.

A prospective assessment of racial/ethnic differences in future mammography behavior among women who had early mammography

BACKGROUND

Twenty-nine percent of women, aged 30 to 39, report having had a mammogram, though sensitivity and specificity are low. We investigate racial/ethnic differences in future mammography behavior among women who had a baseline screening mammogram prior to age 40.

METHODS

Using 1994-2008 data from the Breast Cancer Surveillance Consortium (BCSC), we identified 29,390 women aged 35 to 39 with a baseline screening mammogram. We followed this cohort for 2 outcomes: (i) future BCSC mammography between ages 40 and 45; and (2) among those, delay in screening mammography until ages 43 to 45 compared with ages 40 to 42. Using adjusted log-linear models, we estimated the relative risk (RR) of these outcomes by race/ethnicity, while also considering the impact of false-positive/true-negative (FP/TN) baseline mammography results on these outcomes.

RESULTS

Relative to non-Hispanic white women, Hispanic women had an increased risk of no future BCSC mammography (RR: 1.21, 95% CI: 1.13-1.30); Asian women had a decreased risk (RR: 0.67, 95% CI: 0.61-0.74). Women with a FP result, compared with a TN result, had a decreased risk of no future BCSC mammography (RR: 0.89, 95% CI: 0.85-0.95). Among those with future BCSC screening mammography, African American women were more likely to delay the timing (RR: 1.26, 95% CI: 1.09-1.45). The interaction between race/ethnicity and FP/TN baseline results was not significant.

CONCLUSIONS

Race/ethnicity is differentially associated with future BCSC mammography and the timing of screening mammography after age 40.

IMPACT

These findings introduce the need for research that examines disparities in lifetime mammography use patterns from the initiation of mammography screening.

Does participation to screening unintentionally influence lifestyle behaviour and thus lifestyle-related morbidity?

Cancer is a leading cause of death worldwide and the burden could be reduced by evidence-based strategies for the primary prevention of cancer, the early detection of malignancies and more adequate treatment of cancer patients. Previous research has shown that lifestyle factors are associated with common cancers and that several cancer screening programmes are cost-effective in reducing cancer-specific mortality. But, some recent studies reported that participants of screening programs might unintentionally change their lifestyle. Cancer screening might be a teachable moment or, on the other hand, have a false health certificate effect. Despite that the evidence is scarce, cancer screening might have opportunities for lifestyle improvements, although a possible health certificate effect still remains. Integrated approaches to combine primary and secondary prevention have the potential to optimise the efforts to improve cancer prevention and survival. More research is warranted to investigate evidence-based approaches.
