Self-assessed health, perceived stress and non-participation in breast cancer screening: A Danish cohort study

Factors affecting women's participation in mammography screening in Nordic countries: A systematic review

INTRODUCTION

Mammography screening programs have been implemented in European countries as prevention tools aimed at reducing breast cancer mortality through early detection in asymptomatic women. Nordic countries (Denmark, Finland, Iceland, Norway, Sweden, the Faroe Islands, and Greenland) demonstrated high participation rates; however, breast cancer mortality could be limited by further optimizing screening. This review aimed to explore factors that affect women's participation in mammography screening in Nordic countries.

METHOD

A systematic review of segregated mixed research synthesis using a deductive approach was conducted. The following databases and platforms were searched to identify relevant studies: CINAHL with Full Text (EBSCOHost), MEDLINE (EBSCOHost), PsycInfo (ProQuest), Scopus (Elsevier) and Web of Science Core Collection (SCI-EXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, and ESCI). The Critical Appraisal Skills Program was used for quality assessment. The Health Promotion Model was applied to integrate findings from qualitative and qualitative research. All methodological steps followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

The final selection (16 articles) included studies from three Nordic countries: Denmark (four quantitative studies), Norway (one qualitative and four quantitative studies), and Sweden (three qualitative and seven quantitative studies). Sixty-three factors were identified as barriers, facilitators, or factors with no influence.

CONCLUSION

A substantial number of obtained factors, spread across a wide spectrum, describe (non-)participation in mammography screening as a versatile phenomenon.

IMPLICATIONS FOR PRACTICE

The findings of this review could benefit the mammography staff and providers regarding possible interventions aimed at improving screening participation rates.

Analytic Hierarchy Process Analysis of Patient Preferences for Contrast-Enhanced Mammography Versus MRI as Supplemental Screening Options for Breast Cancer

OBJECTIVE

To guide implementation of supplemental breast screening by assessing patient preferences for contrast-enhanced mammography (CEM) versus MRI using analytic hierarchy process (AHP) methodology.

METHODS

In an institutional review board-approved, HIPAA-compliant protocol, from March 23 to June 3, 2022, we contacted 579 women who had both CEM screening and MRI. Women were e-mailed an invitation to complete an online survey developed using an AHP-based model to elicit preferences for CEM or MRI. Methods for categorical data analysis were used to evaluate factors affecting preferences, under the Bonferroni correction for multiplicity.

RESULTS

Complete responses were received from 222 (38.3%) women; the 189 women with a personal history of breast cancer had a mean age 61.8 years, and the 34 women without a personal history of breast cancer had a mean age of 53.6 years. Of 222 respondents, 157 (70.7%, confidence interval [CI]: 64.7-76.7) were determined to prefer CEM to MRI. Breast positioning was the most important criterion for 74 of 222 (33.3%) respondents, with claustrophobia, intravenous line placement, and overall stress most important for 38, 37, and 39 women (17.1%, 16.7%, and 17.6%), respectively, and noise level, contrast injection, and indifference being emphasized least frequently (by 10 [4.5%], 11 [5.0%], and 13 [5.9%] women, respectively). CEM preference was most prevalent (MRI least prevalent) for respondents emphasizing claustrophobia (37 of 38 [97%], CI: 86.2-99.9); CEM preference was least prevalent (MRI most prevalent) for respondents emphasizing breast positioning (40 of 74 [54%], CI: 42.1-65.7).

CONCLUSIONS

AHP-based modeling reveals strong patient preferences for CEM over MRI, with claustrophobia favoring preference for CEM and breast positioning relatively favoring preference for MRI. Our results should help guide implementation of screening CEM and MRI.

Participation and adherence to mammography screening in the Capital Region of Denmark: The importance of age over time

Mammography screening's effectiveness depends on high participation levels. Understanding adherence patterns over time is important for more accurately predicting future effectiveness. This study analyzed longitudinal adherence to the biennial invitations in the Capital Region of Denmark from 2008-2017. We analyzed participation rates for five-year age groups along with their percent changes in each invitation round using linear regressions. Participation in the mammography screening program increased from 73.1% to 83.1% from 2008-2017. The participation rate among all age groups increased from the first to the fifth round, with the oldest age group having the largest increase (average percent change = 3.66; p-value = 0.03).

Determinants of Non-Participation in Population-Based Breast Cancer Screening: A Systematic Review and Meta-Analysis

Background

Breast cancer (BC) screening can be performed in a screening program (BCSP) or in opportunistic screening. The existing reviews on the determinants of non-participation depend on self-reported data which may be biased. Furthermore, no distinction was made between the probably different determinants of both screening strategies.

Objective

To find the determinants of non-participation in BCSP by means of a meta-analysis.

Methods

PubMed, Embase, and Web of Science were searched for observational studies which quantified factors associated with non-participation in BCSP in a general population. Studies on opportunistic screening and studies using self-reported data were excluded. A random-effect model was used to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs). Potential sources of heterogeneity were explored by stratification of the results.

Results

Twenty-nine studies with in a total of 20,361,756 women were included. Low income (OR: 1.20, 95% CI: 1.10–1.30), low education (OR: 1.18, 95% CI: 1.05–1.32), living far from an assigned screening unit (OR: 1.15, 95% CI: 1.07–1.24), being immigrant (OR: 2.64, 95% CI: 2.48–2.82), and having a male family doctor (OR: 1.43, 95% CI: 1.20–1.61) was associated with higher non-participation in screening. Reminders sent to non-attenders and estimations of ORs (adjusted or not) partly explained substantial heterogeneity.

Conclusion

In this meta-analysis excluding studies on the non-participation in opportunistic screening, or with self-reported data on non-participation, the well-known determinants for non-participation are still significant, but less strong. This analysis only supports the relevance of meta-analysis of studies with registered non-participation in a BCSP.

Does retirement affect secondary preventive care use? Evidence from breast cancer screening

This paper examines the causal impact of retirement on preventive care use by focusing on breast cancer screening. It contributes to a better understanding of the puzzling results in the literature reporting mixed effects on health care consumption at retirement. We use five waves of data from the Eurobarometer surveys conducted between 1996 and 2006, covering 25 different European countries. We address the endogeneity of retirement by using age thresholds for pension eligibility as instrumental variables in a bivariate probit model. We find that retirement reduces mammography use and other secondary preventive care use. Our results suggest that health status, income, and knowledge on cancer prevention and treatment contribute little to our understanding of the effects of retirement. Instead, our evidence suggests important effect heterogeneity based on the generosity of the social health insurance system and organized screening programs.

Impact of Risk-Stratified Therapy on Health Status in Survivors of Childhood Acute Lymphoblastic Leukemia: A Report from the Childhood Cancer Survivor Study

BACKGROUND

Prior studies have identified that survivors of childhood acute lymphoblastic leukemia (ALL) report poor health status. It is unknown how risk-stratified therapy impacts the health status of ALL survivors.

METHODS

We estimated and compared the prevalence of self-reported poor health status among adult (≥18 years) survivors of childhood ALL diagnosed at age <21 years from 1970 to 1999 and sibling controls, excluding proxy reports. Therapy combinations defined treatment groups representative of 1970s therapy (70s), standard- and high-risk 1980s and 1990s therapy (80sSR, 80sHR, 90sSR, 90sHR), and relapse/bone marrow transplant (R/BMT). Log-binomial models, adjusted for clinical and demographic factors, compared outcomes between groups using prevalence ratios (PR) with 95% confidence intervals (CI).

RESULTS

Among 5,119 survivors and 4,693 siblings, survivors were more likely to report poor health status in each domain including poor general health (13.5% vs. 7.4%; PR = 1.92; 95% CI, 1.69-2.19). Compared with 70s, 90sSR and 90sHR were less likely to report poor general health (90sSR: PR = 0.75; 95% CI, 0.57-0.98; 90sHR: PR = 0.58; 95% CI, 0.39-0.87), functional impairment (90sSR: PR = 0.56; 95% CI, 0.42-0.76; 90sHR: PR = 0.63; 95% CI, 0.42-0.95), and activity limitations (90sSR: 0.61; 95% CI, 0.45-0.83; 90sHR: PR = 0.59; 95% CI, 0.38-0.91). An added adjustment for chronic conditions in multivariable models partially attenuated 90sSR risk estimates.

CONCLUSIONS

Risk-stratified ALL therapy has succeeded in reducing risk for poor general health, functional impairment, and activity limitations among more recent survivors of standard- and high-risk therapy.

IMPACT

Future research into the relationship between risk-stratified therapy, health status, and late health outcomes may provide new opportunities to further improve late morbidity among survivors.

Biological correlates before esophageal cancer screening and after diagnosis

Almost 50% of the world's esophageal cancer (EC) cases occur in China, and the impact of cancer screening has long been a controversial topic. The study was designed to evaluate the biological correlates of EC screening and subsequent diagnosis in China. Based on the national cohort of esophageal cancer program, a prospective multicenter study in high-risk regions was conducted from 2017 to 2019. 61 participants received twice esophageal endoscopy screening and pathological biopsy successively (with a mean follow-up of 14.03 months). Box-Cox-power transformation and two-way repeated measures ANOVA were used to evaluate hormone cortisol and immunoglobulin (IgA, IgG, IgM) levels in plasma, reflecting their stress, immune function, and biological correlates before screening and after knowing the diagnosis. The median of cortisol, IgA, IgG, and IgM in pre-screening was 15.46 ug/dL, 1.86 g/L, 12.14 g/L, and 0.91 g/L, corresponding value at post-diagnosis was 15.30 ug/dL, 2.00 g/L, 12.79 g/L, and 0.94 g/L, respectively. No significant differences in biological indicators were found between normal and esophagitis and low-grade intraepithelial neoplasia before screening and after diagnosis. After normality transformation, cortisol, IgA, IgG and IgM levels were (0.25 ± 0.04) U/mL, (0.72 ± 0.13) (g/L), (2.44 ± 0.22) (g/L) and (0.98 ± 0.25) (g/L) before screening, (0.25 ± 0.05) U/mL, (0.70 ± 0.13) (g/L), (2.48 ± 0.21) (g/L) and (1.00 ± 0.25) (g/L) after diagnosis, respectively. Repeated Measures ANOVA showed that the main effects were significant on IgA levels between pre-screening and post-diagnosis (P = 0.019). No interaction effects on biological levels between pre-post screening and esophageal pathology, anxiety states (all P > 0.05). Little biological correlates were found both before screening and after diagnosis. Cortisol and IgA dropped less significantly, while IgM and IgA were increased slightly after diagnosis. Further multi-round longitudinal studies are needed to validate these results.

Combined Effect of Health Status and Primary Care Use on Participation in Cancer Screening: The CONSTANCES Cohort

Background:

The combined association between primary care utilization and health status with breast cancer screening (BCS) and cervical cancer screening (CCS) remains unclear. Our aim was to identify women's profiles based on their health status and primary care utilization and study their associated adherence to BCS and CCS recommendations.

Methods:

Using data from the cohort of people visiting health screening centers (CONSTANCES) in France (2012–2015), we first identified women's profiles based on their health status (self-perceived health, physical, and mental health) and primary care utilization (visit to the General Practitioner [GP], uptake of blood tests) using a multiple correspondence analysis and a hierarchical cluster analysis. We then investigated the association of these profiles to BCS and CCS using logistic regression models adjusted for age, smoking status, sociodemographic and socioeconomic characteristics, and the regularity of gynecologist consultation.

Results:

We identified five distinct profiles of women with contrasted participation in BCS (n = 14,122) and CCS (n = 27,120). In multivariate analyses, cancer screening participation increased from women with very good health and poor primary care utilization, to those with poor health and frequent visits to the GP, and those with very good health and average primary care utilization. The most favorable profiles regarding cancer screening rates were women with average-to-poor health and regular visits to the GP and uptake of blood tests.

Conclusions:

Our results suggest that policies aiming at increasing cancer screening participation should simultaneously account for women's use of primary care and health and consider more specific subgroups than what is usually done. Further research should investigate factors motivating cancer screening practice, such as women's beliefs regarding cancer screening and women's psychological characteristics.

Non-participation in mammographic screening - experiences of women from a region in Sweden

Background

Understanding women’s life conditions regarding their non-participation in different health-promoting and disease-preventing activities is important as it may draw attention to potential areas for improvement in the healthcare sector. Mammographic screening, a disease-preventing service, facilitates early detection of any potential malignancies and consequently prompts initiation of treatment. The reasons for non-participation in mammographic screening can be understood from different perspectives, such as socioeconomic and lifestyle-related determinants of health. This study aims to gain a deeper understanding of women’s experiences and perceptions about non-participation in mammographic screening in a Swedish region with a single mammographic facility.

Methods

Data from individual semi-structured interviews, conducted in 2018 with eleven women between the ages of 48 and 73, were analysed by a qualitative content analysis.

Results

The findings reveal three main categories: 1) doubts regarding mammographic screening and its organisation, 2) sense and sensibility in the decision to refrain from mammographic screening, and 3) dependency and options. These three categories indicate aspects, such as the individual’s life situation, accessibility to the offered service, and the flexibility of the healthcare system, that need to be considered to improve the organisation of mammographic screening.

Conclusion

Listening to the women’s voices regarding their experiences and perceptions about mammographic screening is important as individual characteristics and social circumstances interact with healthcare and affect the degree of participation.

New Educational Model to Promote Breast Cancer-Preventive Behaviors (ASSISTS): Development and First Evaluation

BACKGROUND

The prevalence of breast cancer in Iran has increased. An effective approach to decrease the burden of breast cancer is prevention.

OBJECTIVE

The aim of this study was to develop and evaluate an educational model, called the ASSISTS, for promoting breast cancer-preventive behaviors in women.

METHODS

A multiphase method was used to develop the model designed to promote breast cancer prevention behaviors. A conceptual model was generated based on a secondary analysis of qualitative data. Then, a structural equation model technique was used to test the relationships among the model constructs.

RESULTS

The analysis revealed that 7 constructs could be extracted, namely, perceived social support, attitude, motivation, self-efficacy, information seeking, stress management, and self-care. Based on these constructs, a conceptual model was built and tested using structural equation modeling. The model fit was good, and the model confirmed significant relationships among the 7 constructs of breast cancer prevention.

CONCLUSION

Findings revealed that self-care behavior and stress management are influenced directly by attitude, motivation, self-efficacy, information seeking, and social support. In addition, women seek more information when they are motivated, have more self-efficacy, have a more positive attitude toward breast cancer prevention, and experience more social support.

IMPLICATION FOR PRACTICE

Cancer nurses can be at the forefront of breast cancer prevention. Because they can play a pivotal role in providing information, they can reduce women's stress and increase their self-care behavior. In addition, their social support can positively influence Iranian women's attitude, motivation, and self-care behavior. Furthermore, implementing educational programs based on this model might encourage women to practice preventive behaviors.

Health and health belief factors associated with screening and help-seeking behaviours for breast cancer: A systematic review and meta-analysis of the European evidence

PURPOSE

The aim of this systematic review was to identify health or health belief factors associated with mammography attendance or with self-initiated medical help-seeking for breast cancer symptoms among women in Europe.

METHODS

Five databases were searched for articles published between 2005 and 2018. Meta-analyses were conducted for 13 factors related to screening attendance and two factors associated with help-seeking behaviour. Where there were too few studies to include in the meta-analysis, a narrative synthesis was undertaken.

RESULTS

Sixty-five studies were included. Never having had cervical screening (d = -.72, p < .001) and higher perceived barriers to mammography (d = -.40, p < .001) were associated with lower levels of screening attendance. Possessing health insurance (d = .49, p < .001), greater perceived benefits (d = .31, p < .001) and motivation (d = .36, p = .003) towards screening, and higher perceived seriousness (d = .24, p = .019) and susceptibility (d = .20, p = .024) towards breast cancer were associated with a higher level of screening attendance. Presenting with a non-lump symptom was associated with a longer time to presentation (d = .32, p < .001). The narrative synthesis revealed that previous benign breast disease was associated with a higher level of screening attendance but with a longer time to presentation.

CONCLUSIONS

The review identified key similarities in factors associated with screening and help-seeking behaviours which offer scope for combined interventions aimed at women that target both behaviours. Furthermore, the review highlighted that fewer studies have focused on help-seeking behaviour, despite two thirds of breast cancer cases being self-detected. Future research should further examine predictors of help-seeking behaviour including a focus on modifiable factors, such as BMI, and physical activity.

Depressive symptoms, neuroticism, and participation in breast and cervical cancer screening: Cross-sectional and prospective evidence from UK Biobank

Objective

To assess the cross‐sectional and prospective associations between depressive symptoms, neuroticism, and participation in breast and cervical screening in the UK.

Methods

Women in the UK Biobank cohort with complete data who were eligible for breast cancer screening (aged 50‐70 years, N = 143 461) and/or cervical screening (<65 years, N = 141 753) at baseline recruitment (2006‐2010) and those with follow‐up data (2014‐2019) were identified (N = 11 050 and N = 9780 for breast and cervical screening). Depressive symptoms and neuroticism were self‐reported at baseline (range 0‐12 with higher scores reflecting greater severity). Primary outcomes were reporting being up to date with breast and cervical screening. For prospective analyses, patterns of screening participation from baseline to follow‐up were identified. Logistic regression was used to analyse associations, adjusted for potential confounding factors.

Results

More severe depressive symptoms were associated with reduced likelihood of breast (OR = 0.960, 95% CI: 0.950,0.970) and cervical (OR = 0.958, 95% CI: 0.950,0.966) screening participation, in cross‐sectional analyses. Higher neuroticism scores were associated with reduced cervical screening participation, but the opposite was found for breast cancer screening. Examination of individual neuroticism items revealed that anxiety and worry were associated with increased breast screening. At follow‐up, higher baseline depressive symptoms were related to decreased cervical screening (OR = 0.955, 95% CI: 0.913,0.999), but not with breast screening.

Conclusions

More severe depressive symptoms may be a barrier for breast and cervical screening and could be an indicator for more proactive strategies to improve uptake.
