Psychosocial determinants of socioeconomic inequalities in cancer screening participation: a conceptual framework

Disparity in cognitive factors related to cancer screening uptake based on the theory of planned behavior

INTRODUCTION

Early detection of cancer is a highly effective way to decrease cancer-related deaths. The purpose of this study was to determine the disparity in cognitive factors related to cancer screening uptake based on the theory of planned behavior (TPB).

METHODS

In this cross-sectional study, conducted in Kermanshah County, the west of Iran, during 2019, a total of 1760 people aged 30 to 75 years old, were randomly selected to participate voluntarily in the study. Participants filled out a questionnaire including the socio demographic variables, socioeconomic status (SES), TPB variables, and cancer screening uptake behaviors.

RESULTS

The mean age of respondents was 45.28. 44.96% of the participants had undergone cancer screening at least once. Socioeconomic status (SES) and gender had the most significant impact on the disparity in cancer screening uptake, with contributions of 74.64% and 22.25% respectively. Women were 8.63 times more likely to be screened than men. Participants with a family history of cancer had a 2.84 times higher chance of being screened. Single individuals were significantly less likely to be screened compared to married individuals. The concentration index for attitude, subjective norms (SN), perceived behavior control (PBC), behavior intention, and cancer screening uptake was 0.0735, 0.113, 0.333, 0.067, and 0.132 respectively. Intention (Beta = 0.225 and P: < 0.001) is a significant predictor of cancer screening behaviors.

CONCLUSION

The findings of this study are highly valuable for health policymakers in Iran. They emphasize the significance of creating, executing, and assessing campaigns that promote intention, PBC and SN, particularly among disadvantaged individuals. By doing so, we can effectively decrease the disparity in cancer screening rates. It is crucial to prioritize men, single individuals, and disadvantaged groups in cancer screening promotion programs. This knowledge can be utilized to develop an intervention that is guided by theory and supported by evidence, with the aim of increasing cancer screening rates and minimizing disparities.

Lack of social support, gender and colorectal cancer screening participation across Europe: How do screening programmes mitigate the effect of social support for men and women?

This study investigates how a lack of social support differentially affects men and women's colorectal cancer (CRC) screening participation, considering different screening strategies implemented across European countries. Although health sociology has stressed gender differences in social support and its effects on health behaviours, this was overlooked by cancer screening research. Using a data set of 65,961 women and 55,602 men in 31 European countries, we analysed the effect of social support variables on CRC screening uptake. We found that living alone and lower perceived social support were associated with lower screening uptake for both men and women. These effects were, however, stronger among men. Population-based screening programmes mitigated these effects, particularly for women, but not for men living alone. In countries with opportunistic screening programmes, social support variables remained associated with screening uptake. We conclude that cancer screening interventions should pay attention to social support and its gender-differentiated effects.

Impact of screening participation on modelled mortality benefits of a multi-cancer early detection test by socioeconomic group in England

BACKGROUND

Cancer burden is higher and cancer screening participation is lower among individuals living in more socioeconomically deprived areas of England, contributing to worse health outcomes and shorter life expectancy. Owing to higher multi-cancer early detection (MCED) test sensitivity for poor-prognosis cancers and greater cancer burden in groups experiencing greater deprivation, MCED screening programmes may have greater relative benefits in these groups. We modelled potential differential benefits of MCED screening between deprivation groups in England at different levels of screening participation.

METHODS

We applied the interception multi-cancer screening model to cancer incidence and survival data made available by the National Cancer Registration and Analysis Service in England to estimate reductions in late-stage diagnoses and cancer mortality from an MCED screening programme by deprivation group across 24 cancer types. We assessed the impact of varying the proportion of people who participated in annual screening in each deprivation group on these estimates.

RESULTS

The modelled benefits of an MCED screening programme were substantial: reductions in late-stage diagnoses were 160 and 274 per 100 000 persons in the least and most deprived groups, respectively. Reductions in cancer mortality were 60 and 99 per 100 000 persons in the least and most deprived groups, respectively. Benefits were greatest in the most deprived group at every participation level and were attenuated with lower screening participation.

CONCLUSIONS

For the greatest possible population benefit and to decrease health inequalities, an MCED implementation strategy should focus on enhancing equitable, informed participation, enabling equal participation across all socioeconomic deprivation groups.

Didactic and narrative persuasion: An experiment to promote colorectal cancer screening

We tested whether a didactic and a narrative video (i.e. educational content and personal stories versus irrelevant information) could boost colorectal cancer (CRC) screening intention directly and through cognitive predictors of CRC screening behavior. We also tested whether exposure to a story changed participants' affective forecasting, reducing the perception of negative emotions associated with CRC screening (disgust, embarrassment, and fear). The study was conducted online with a between-participants design and recruiting a convenience sample (N = 375). We found that, compared with watching the control video, being exposed to the narrative video about CRC screening was indirectly associated with greater screening intention via vicarious experience and positive attitudes, whereas watching the didactic video was positively associated with CRC screening intention only among participants who had received an invitation letter but did not get screened, and among those yet to receive an invitation to screen. In the latter group, screening intention was boosted through positive attitudes. Our findings do not confirm that stories change affective forecasting, but narration likely fosters messages acceptance through vicarious experience. We also found support for the effectiveness of physicians' recommendations in promoting CRC screening, an intervention that might be effectively administered through a generalized, cost-effective video.

Knowledge of cancer symptoms and risk factors: A cross-sectional study from a developing country

The delayed presentation of cancer patients to healthcare facilities for diagnosis is a pressing issue, as late-stage cancer cases are often more challenging to treat effectively. In low-resource settings, such as those with limited access to healthcare facilities, the impact of inadequate awareness of cancer signs and symptoms can be particularly severe. Therefore, this study aimed to evaluate public knowledge of cancer signs and symptoms and risk factors in the context of Jordan. This cross-sectional study was conducted among participants from all settings. Data was obtained from an Arabic version of the cancer awareness measure (CAM), which was answered online. It described demographic data and knowledge of cancer prevalence, age-related risk, signs, symptoms, and risk factors in recall and recognition-type questions. Participants (n = 1998) completed the questionnaire with a Median age of 35 and an interquartile range of 24. About half (n = 1070) thought that cancer is unrelated to age. Most participants identified breast cancer as the most common cancer among women (81%). Awareness of cancer signs/symptoms significantly differed in the level of knowledge in favor of females. The symptom "unexplained weight loss" was most commonly recognized (66.3%) and "persistent difficulty swallowing" the least (42.6%). As for risk factors, "smoking" was the most identified (76.9%) and "eating less than 5 portions of fruits and vegetables a day" was the least (19%), and "doing <30 minutes of moderate physical activity 5 times a week" as a close second least (19.95%). Females identified "smoking," "passive smoking," "HPV infection," and "having a close relative with cancer" as risk factors significantly more than males. Those with good economic status were more aware that smoking is a cancer risk factor by 1.51 times compared to those with poor economic status. To enhance early diagnosis and presentation in Jordan, there is a need for increased public awareness of the signs, symptoms, and risk factors of cancer. One effective strategy to achieve this goal is to conduct targeted public campaigns that cater to different population groups, such as the youth, to improve their understanding and ensure that the message resonates.

Determinants of routine cervical screening participation in underserved women: a qualitative systematic review

OBJECTIVE

Routine, population-wide cervical screening programmes reduce cervical cancer incidence and mortality. However, socioeconomically deprived communities and ethnic minority groups typically have lower uptake in comparison to the general population and thus are described as 'underserved.' A systematic qualitative literature review was conducted to identify relevant determinants of participation for these groups.

METHODS

Online databases were searched for relevant literature from countries with well-established, call-recall screening programmes. Overall, 24 articles were eligible for inclusion. Data was synthesized via Framework synthesis. Dahlgren & Whitehead's social model of health was used as a broad a priori coding framework.

RESULTS

Participation was influenced by determinants at multiple levels. Overall, patient-provider relationships and peer support facilitated engagement. Cultural disparities, past healthcare experience and practical barriers hindered service access and exacerbated negative thoughts, feelings and attitudes towards participation. Complex interrelationships between determinants suggest barriers have a cumulative effect on screening participation.

CONCLUSIONS

These findings present a framework of psychosocial determinants of cervical screening uptake in underserved women and emphasise the role of policy makers and practitioners in reducing structural barriers to screening services. Additional work, exploring the experience of those living within socioeconomically disadvantaged areas, is needed to strengthen understanding in this area.

Trends in Participation in Rubella Antibody Testing among Working-Aged Men during Annual Health Check-Ups from 2019 to 2022 in Japan

In 2019, the Japanese government established a scheme for rubella antibody testing of men born between 1962 and 1978 during workplace health check-ups. However, the use of vouchers for rubella antibody testing was limited. Health check-up data analyses are needed to determine the reason why rubella antibody testing is not widely used. In this study, we aimed to describe changes in rubella antibody test-taking behavior during health check-ups during the first 3 years of the rubella catch-up campaign in Japan. In 2019, 2020, and 2021 (2020 in some areas) vouchers were sent to men born during the fiscal years 1972-1978, 1966-1971, and 1962-1965, respectively. We calculated the prevalence in men born between 1962 and 1978 who underwent rubella antibody testing during mandatory health check-ups under the Industrial Health and Safety Act. Rubella antibody testing uptake was relatively high (approximately 15%) in all three age groups soon after the distribution of the vouchers and then declined to below 2% during the second and third years. Further population-based approaches with continuous public engagement are required in workplaces to effectively promote and expand the rubella vaccination program in Japan.

What do women think about having received their breast cancer risk as part of a risk-stratified NHS Breast Screening Programme? A qualitative study

BACKGROUND

Risk-stratified screening is being considered for national breast screening programmes. It is unclear how women experience risk-stratified screening and receipt of breast cancer risk information in real time. This study aimed to explore the psychological impact of undergoing risk-stratified screening within England's NHS Breast Screening Programme.

METHODS

Individual telephone interviews were conducted with 40 women who participated in the BC-Predict study and received a letter indicating their estimated breast cancer risk as one of four risk categories: low (<2% 10-year risk), average (2-4.99%), above average (moderate; 5-7.99%) or high (≥8%). Audio-recorded interview transcriptions were analysed using reflexive thematic analysis.

RESULTS

Two themes were produced: 'From risk expectations to what's my future health story?' highlights that women overall valued the opportunity to receive risk estimates; however, when these were discordant with perceived risk, this causes temporary distress or rejection of the information. 'Being a good (woman) citizen' where women felt positive contributing to society but may feel judged if they then cannot exert agency over the management of their risk or access follow-up support CONCLUSIONS: Risk-stratified breast screening was generally accepted without causing long-lasting distress; however, issues related to risk communication and access to care pathways need to be considered for implementation.

Understanding Cancer Screening Intention Among Physically Active Adults Ages 18-49

Ideal efforts for cancer prevention would include lifestyle modifications along with routine, age-eligible cancer screening. Employing an asset-based approach within vulnerable populations already engaging in at least one healthy behavior (i.e., physical activity) may be an ideal way to further reduce cancer risk across peer groups with low cancer screening rates. Guided by the theory of planned behavior (TPB), the aim of this study was to identify constructs associated with cancer screening intentions among young to middle aged adults for influencing educational and behavioral interventions designed to promote cancer prevention. A cross-sectional, web-based survey was utilized to assess attitudes, subjective norms, perceived behavioral control, and intention to screen for cancer among physically active adults aged 18-49 years. Descriptive and bivariate analyses were conducted to characterize the sample, and hierarchical linear regression analyses were conducted to assess the influence of sociodemographic variables and TPB constructs on cancer screening intentions. Age, female sex, reporting a routine doctor's visit, reported knowledge of physical activity as a lifestyle behavior to reduce cancer risk, and an increased number of motivating factors for engaging in physical activity were significantly associated with higher cancer screening intention (P < 0.001). With the addition of TPB constructs (i.e., subjective norms and perceived behavioral control), the final analytic model accounted for 31% of the variance in intention to screen for cancer. Findings suggest that the TPB could be used to tailor or design asset-based, cancer education interventions to effectively promote age-eligible cancer screenings among physically active adults. Educational content to increase social support for cancer screening and enhance perceived behavioral control to complete screening is essential in this population.

Improving colorectal cancer screening - consumer-centred technological interventions to enhance engagement and participation amongst diverse cohorts

The current "Gold Standard" colorectal cancer (CRC) screening approach of faecal occult blood test (FOBT) with follow-up colonoscopy has been shown to significantly improve morbidity and mortality, by enabling the early detection of disease. However, its efficacy is predicated on high levels of population participation in screening. Several international studies have shown continued low rates of screening participation, especially amongst highly vulnerable lower socio-economic cohorts, with minimal improvement using current recruitment strategies. Research suggests that a complex of dynamic factors (patient, clinician, and the broader health system) contribute to low citizen engagement. This paper argues that the challenges of screening participation can be better addressed by (1) developing dynamic multifaceted technological interventions collaboratively across stakeholders using human-centered design; (2) integrating consumer-centred artificial intelligence (AI) technologies to maximise ease of use for CRC screening; and (3) tailored strategies that maximise population screening engagement, especially amongst the most vulnerable.

Understanding patient barriers and facilitators to uptake of lung screening using low dose computed tomography: a mixed methods scoping review of the current literature

BACKGROUND

Targeted lung cancer screening is effective in reducing mortality by upwards of twenty percent. However, screening is not universally available and uptake is variable and socially patterned. Understanding screening behaviour is integral to designing a service that serves its population and promotes equitable uptake. We sought to review the literature to identify barriers and facilitators to screening to inform the development of a pilot lung screening study in Scotland.

METHODS

We used Arksey and O'Malley's scoping review methodology and PRISMA-ScR framework to identify relevant literature to meet the study aims. Qualitative, quantitative and mixed methods primary studies published between January 2000 and May 2021 were identified and reviewed by two reviewers for inclusion, using a list of search terms developed by the study team and adapted for chosen databases.

RESULTS

Twenty-one articles met the final inclusion criteria. Articles were published between 2003 and 2021 and came from high income countries. Following data extraction and synthesis, findings were organised into four categories: Awareness of lung screening, Enthusiasm for lung screening, Barriers to lung screening, and Facilitators or ways of promoting uptake of lung screening. Awareness of lung screening was low while enthusiasm was high. Barriers to screening included fear of a cancer diagnosis, low perceived risk of lung cancer as well as practical barriers of cost, travel and time off work. Being health conscious, provider endorsement and seeking reassurance were all identified as facilitators of screening participation.

CONCLUSIONS

Understanding patient reported barriers and facilitators to lung screening can help inform the implementation of future lung screening pilots and national lung screening programmes.

The Effects of Cancer Beliefs and Sociodemographic Factors on Colorectal Cancer Screening Behaviours in Newfoundland and Labrador

Objectives: This study investigated the beliefs about cancer treatment, outcomes, and screening among adults aged 50−74 in Newfoundland and Labrador and whether these beliefs or sociodemographic factors were associated with differences in colorectal cancer (CRC) screening behaviours. Methods: This analysis uses data collected from an online survey of adults on cancer awareness and prevention in NL. Chi-square tests were used to assess differences in distributions of beliefs based on CRC screening behaviour. Logistic regression was used to identify sociodemographic factors independently associated with CRC screening behaviour. Results: A total of 724 participants were included in the analysis, 57.4% of which had ever had CRC screening. Most held positive beliefs about cancer outcomes and treatment. Only beliefs about screening affected CRC screening behaviour. People who never had CRC screening were more likely to believe their worries about what might be found would prevent them from screening (χ2 = 9.380, p = 0.009); screening is only necessary if they have symptoms (χ2 = 15.680, p < 0.001); and screening has a high risk of leading to unnecessary surgery (χ2 = 6.824, p = 0.032). Regression identified that men had higher likelihood of having had CRC screening than women in our study (OR = 1.689, 95%CI = 1.135−2.515), as did all age groups compared to ages 50−54. No associations were found with the other sociodemographic factors studied. Conclusion: Beliefs about cancer screening appear to play some role in CRC screening behaviour, but the absolute effect was small. The relatively few sociodemographic associations with screening behaviour suggest that NL’s CRC screening program is equitably reaching people from different socioeconomic backgrounds.

Optimizing the implementation of lung cancer screening in Scotland: Focus group participant perspectives in the LUNGSCOT study

INTRODUCTION

Targeted lung cancer screening is effective in reducing lung cancer and all-cause mortality according to major trials in the United Kingdom and Europe. However, the best ways of implementing screening in local communities requires an understanding of the population the programme will serve. We undertook a study to explore the views of those potentially eligible for, and to identify potential barriers and facilitators to taking part in, lung screening, to inform the development of a feasibility study.

METHODS

Men and women aged 45-70, living in urban and rural Scotland, and either self-reported people who smoke or who recently quit, were invited to take part in the study via research agency Taylor McKenzie. Eleven men and 14 women took part in three virtual focus groups exploring their views on lung screening. Focus group transcripts were transcribed and analysed using thematic analysis, assisted by QSR NVivo.

FINDINGS

Three overarching themes were identified: (1) Knowledge, awareness and acceptability of lung screening, (2) Barriers and facilitators to screening and (3) Promoting screening and implementation ideas. Participants were largely supportive of lung screening in principle and described the importance of the early detection of cancer. Emotional and psychological concerns as well as system-level and practical issues were discussed as posing barriers and facilitators to lung screening.

CONCLUSIONS

Understanding the views of people potentially eligible for a lung health check can usefully inform the development of a further study to test the feasibility and acceptability of lung screening in Scotland.

PATIENT OR PUBLIC CONTRIBUTION

The LUNGSCOT study has convened a patient advisory group to advise on all aspects of study development and implementation. Patient representatives commented on the focus group study design, study materials and ethics application, and two representatives read the focus group transcripts.

The distillation method: A novel approach for analyzing randomized trials when exposure to the intervention is diluted

OBJECTIVE

To introduce a novel analytical approach for randomized controlled trials that are underpowered because of low participant enrollment or engagement.

DATA SOURCES

Reanalysis of data for 805 patients randomized as part of a pilot complex care intervention in 2015-2016 in a large delivery system. In the pilot randomized trial, only 64.6% of patients assigned to the intervention group participated.

STUDY DESIGN

A case study and simulation. The "Distillation Method" capitalizes on the frequently observed correlation between the probability of subjects' participation or engagement in the intervention and the magnitude of benefit they experience. The novel method involves three stages: first, it uses baseline covariates to generate predicted probabilities of participation. Next, these are used to produce nested subsamples of the randomized intervention and control groups that are more concentrated with subjects who were likely to participate/engage. Finally, for the outcomes of interest, standard statistical methods are used to re-evaluate intervention effectiveness in these concentrated subsets.

DATA EXTRACTION METHODS

We assembled secondary data on patients who were randomized to the pilot intervention for one year prior to randomization and two follow-up years. Data included program enrollment status, membership data, demographics, utilization, costs, and clinical data.

PRINCIPAL FINDINGS

Using baseline covariates only, Generalized Boosted Regression Models predicting program enrollment performed well (AUC 0.884). We then distilled the full randomized sample to increasing levels of concentration and reanalyzed program outcomes. We found statistically significant differences in outpatient utilization and emergency department utilization (both follow-up years), and in total costs (follow-up year two only) at select levels of population concentration.

CONCLUSIONS

By offering an internally valid analytic framework, the Distillation Method can increase the power to detect effects by redefining the estimand to subpopulations with higher enrollment probabilities and stronger average treatment effects while maintaining the original randomization.

Protocol for a feasibility study of a cancer symptom awareness campaign to support the rapid diagnostic centre referral pathway in a socioeconomically deprived area: Targeted Intensive Community-based campaign To Optimise Cancer awareness (TIC-TOC)

INTRODUCTION

Rapid diagnostic centres (RDCs) are being implemented across the UK to accelerate the assessment of vague suspected cancer symptoms. Targeted behavioural interventions are needed to augment RDCs that serve socioeconomically deprived populations who are disproportionately affected by cancer, have lower cancer symptom awareness and are less likely to seek help for cancer symptoms. The aim of this study is to assess the feasibility and acceptability of delivering and evaluating a community-based vague cancer symptom awareness intervention in an area of high socioeconomic deprivation.

METHODS AND ANALYSIS

Intervention materials and messages were coproduced with local stakeholders in Cwm Taf Morgannwg, Wales. Cancer champions will be trained to deliver intervention messages and distribute intervention materials using broadcast media (eg, local radio), printed media (eg, branded pharmacy bags, posters, leaflets), social media (eg, Facebook) and attending local community events. A cross-sectional questionnaire will include self-reported patient interval (time between noticing symptoms to contacting the general practitioner), cancer symptom recognition, cancer beliefs and barriers to presentation, awareness of campaign messages, healthcare resource use, generic quality of life and individual and area-level deprivation indicators. Consent rates and proportion of missing data for patient questionnaires (n=189) attending RDCs will be measured. Qualitative interviews and focus groups will assess intervention acceptability and barriers/facilitators to delivery.

ETHICS AND DISSEMINATION

Ethical approval for this study was given by the London-West London & GTAC Research Ethics (21/LO/0402). This project will inform a potential future controlled study to assess intervention effectiveness in reducing the patient interval for vague cancer symptoms. The results will be critical to informing national policy and practice regarding behavioural interventions to support RDCs in highly deprived populations.

Cancer as a death sentence: developing an initial program theory for an IVR intervention

To address current trends in poor health-seeking behaviour and late cancer diagnosis in many low- and middle-income countries, like Uganda, it is important to explore innovative awareness building interventions. One possible intervention is a common digital format, an interactive voice response (IVR) system, which is suitable for individuals with low technological and reading literacy. It is increasingly acknowledged that developing digital interventions requires co-creation with relevant stakeholders and explication of program developers’ assumptions, to make them effective, sustainable, and scalable. To this end, we sought to develop an initial program theory for a co-created IVR system for cancer awareness in Uganda. Utilising principles of the realist approach, a qualitative exploratory study was conducted through seven focus group discussions (FGDs) with people living with cancer (PLWC), health workers, and policy makers. Thematic analysis of the transcripts resulted in the emergence of four major themes. Through all themes the most consistent finding was that myths, misconceptions, and misinformation about cancer were related to every aspect of the cancer journey and influenced the experiences and lives of PLWC and their caregivers. Participants were positive about the potential of an IVR system but also had reservations about the design and reach of the system. The resulting initial program theory proposes that a context-specific IVR system has the potential to improve awareness on cancer, provided attention is given to aspects such as language, message framing, and accuracy.

Socio-economic inequalities in cancer survival: how do they translate into Number of Life-Years Lost?

BACKGROUND

We aimed to investigate the impact of socio-economic inequalities in cancer survival in England on the Number of Life-Years Lost (NLYL) due to cancer.

METHODS

We analysed 1.2 million patients diagnosed with one of the 23 most common cancers (92.3% of all incident cancers in England) between 2010 and 2014. Socio-economic deprivation of patients was based on the income domain of the English Index of Deprivation. We estimated the NLYL due to cancer within 3 years since diagnosis for each cancer and stratified by sex, age and deprivation, using a non-parametric approach. The relative survival framework enables us to disentangle death from cancer and death from other causes without the information on the cause of death.

RESULTS

The largest socio-economic inequalities were seen mostly in adults <45 years with poor-prognosis cancers. In this age group, the most deprived patients with lung, pancreatic and oesophageal cancer lost up to 6 additional months within 3 years since diagnosis than the least deprived. For most moderate/good prognosis cancers, the socio-economic inequalities widened with age.

CONCLUSIONS

More deprived patients and particularly the young with more lethal cancers, lose systematically more life-years than the less deprived. To reduce these inequalities, cancer policies should systematically encompass the inequities component.

The impact of COVID ‐19 on cancer care of outpatients with low socioeconomic status

Patients with low socioeconomic status (SES) are among the most underserved groups of people regarding cancer care. Analyzing the impact of the coronavirus‐induced disease 2019 (COVID‐19) pandemic on health care disparities and calling attention to inequalities in cancer care is crucial to justify and initiate adequate countermeasures. We aimed to determine whether the COVID‐19 pandemic aggravated health care disparities of cancer outpatients related to their SES and analyzed patient data of the largest university center providing services for patients with hematologic and oncologic disorders in Austria from 2018 to 2021. SES was assessed using three indicators: monthly net household income, level of education and occupational prestige. In total, 1217 cancer outpatients (51.1% female) with a mean age of 59.4 years (SD = 14.2) participated. In the first year of the pandemic, the relative proportion of individuals with low income, low education level and low occupational prestige seeking cancer care at our outpatient center decreased significantly (P ≤ .015). The strongest indicator was income, with a consistent effect throughout the first pandemic year. Countermeasures and specific interventions to support cancer patients with low SES in their access to health care should be initiated and prioritized.

Self-efficacy and importance of participation reasons as predictors for prostate cancer screening intention in African American men

Objective: African American men have higher lifetime risk of developing prostate cancer (PCa), and face more health burdens from this disease due in part to limited participation in cancer screening. Therefore, it is important to study psychosocial factors associated with screening intention in African American men. Guided by social cognitive theory, the current study aims to examine the role of self-efficacy and importance of participation reasons as predictors of PCa screening intention in African American men.Design: This is a primary analysis using data collected from African American men in northeast Ohio and the Southeastern United States. PCa screening intention and self-efficacy were measured by single-item questions. Importance of participation reasons was measured in four domains: psychological, convenience, awareness, and medical. Hierarchical binary logistic regression was used to predict PCa screening intention in African American men.Results: The sample size was 174. The average age was 46.52. Adding self-efficacy and reasons for participation significantly improved prediction for PCa screening intention in African American men (Δχ² = 55.28, p < .001). The final model had χ² = 69.63 (p < .001). Higher self-efficacy (OR = 2.56, p < .05), more perceived importance of psychological reasons (OR = 2.42, p < .001) and medical reasons (OR = 1.10, p < .05) were significant predictors. Also, the perceived chance of developing PCa predicted higher odds of PCa screening intention.Conclusions: Enhancing self-efficacy might be an important intervention focus for African American men to improve PCa screening intention. In addition, the findings suggest that African American men intend to have PCa screening because they experience worries or physical symptoms, and unlikely because it is convenient to get screening or recommended by family members and friends. Thus, intervention efforts could focus on enhancing PCa knowledge and informed decision-making about PCa screening among African American men.

Barriers and facilitators to participate in the colorectal cancer screening programme in Flanders (Belgium): a focus group study

OBJECTIVE

In Flanders (Belgium), a population-based colorectal cancer (CRC) screening programme offers a faecal immunochemical test (FIT) biennially to Flemish citizens aged 50-74 years. A FIT uptake of only 51,5% in 2018 is significantly lower among men, lower income groups and among people with other than the Belgian nationality.The objective of this study was to identify attitudes, barriers and facilitators to participate in the Flemish CRC screening programme.

METHODS

Qualitative study using focus group discussions (FGDs) with non-participants in the Flemish CRC screening programme. Four FGDs were held with non-migrant Flemish population groups, and four were held with Turkish migrants (41 participants).

RESULTS

Feeling healthy, fear of cancer and embarrassment to talk about CRC screening emerged as common barriers in all FGDs. Having other priorities (non-migrant group) and a lack of understanding mainly due to a language barrier (Turkish migrants) differed between the two groups. Providing face-to-face information, information in group and GP recommendation were perceived as important facilitators to CRC screening in both groups. More publicity and making CRC screening more of a routine (non-migrant group) and offering translated information (Turkish migrants) were the suggested facilitators that differed between the groups.

CONCLUSIONS

Several common and some group-specific barriers and facilitators appeared to play a role in the decision to participate in the CRC screening programme. In order to improve informed decision making and participation in the CRC screening programme in Flanders, the options of more GP involvement, targeted information events, and adapted reminder letters are currently being explored.

Socio-economic Inequality of Utilization of Cancer Testing in Europe: A Cross-Sectional Study

There are currently screening programmes for breast, cervical and colorectal cancer in many European countries. However, the uptake of cancer screening in general may vary within and between countries. The aim of this study is to assess the inequalities in testing utilization by socio-economic status and whether the amount of inequality varies across European regions. We conducted an analysis based on cross-sectional data from the second wave of the European Health Interview Survey from 2013 to 2015. We analysed the use of breast, cervical, and colorectal cancer testing by socio-economic position (household income, educational level and employment status), socio-demographic factors, self-perceived health and smoking behaviour, by using multinomial logistic models, and inequality measurement based on the Slope index of inequality (SII) and Relative index of inequality (RII). The results show that the utilization of mammography (Odds Ratio (OR) = 0.55, 95% confidence interval (95%CI):0.50–0.61), cervical smear tests (OR = 0.60, 95%CI:0.56–0.65) and colorectal testing (OR = 0.82, 95%CI:0.78–0.86) was overall less likely among individuals within a low household income compared to a high household income. Also, individuals with a non-EU country of birth, low educational level and being unemployed (or retired) were overall less likely to be tested. The income-based inequality in breast (SII = 0.191;RII = 1.260) and colorectal testing utilization (SII = 0.161;RII = 1.487) was the greatest in Southern Europe. For cervical smears, this inequality was greatest in Eastern Europe (SII = 0.122;RII = 1.195). We concluded that there is considerable inequality in the use of cancer tests in Europe, with inequalities associated with household income, educational level, employment status, and country of birth.

Development and psychometric testing of the self-regulatory questionnaire for lung cancer screening (SRQ-LCS)

BACKGROUND

Research implicates psychological factors in low uptake of lung cancer screening. We developed and psychometrically tested a standardised measure of these psychological determinants in preparation for a prospective, longitudinal cohort study of screening uptake.

METHODS

Leventhal's Common-Sense Model of Self-Regulation of Health and Illness provided the theoretical framework to generate the initial item pool. Items were refined during expert review and cognitive interviews which tested for face validity, redundancy, acceptability and comprehensibility. An online survey piloted the refined pool with 1500 current and former (quit ≤ 15 years) smokers aged 55-80. The response distributions, internal reliability and factor structure determined the final retained constructs. Regression analyses examined these constructs' associations with screening intention, smoking status and demographics.

RESULTS

The final measure included seven factor-derived subscales (consequences, personal control, treatment control, illness coherence, emotional representation, behavioural response and appraisal, risk perception) with Cronbach's alphas ranging from 0.59 to 0.91 and four single-item questions (response efficacy for smoking cessation, treatment intention, perceived stigma and lung cancer survival). Most constructs were associated with smoking status and screening intention (p's < .05).

CONCLUSIONS

The Self-Regulatory Questionnaire for Lung Cancer Screening (SRQ-LCS) is an acceptable, reliable and valid measure for investigating the psychological determinants of screening uptake.

Effects of workplace skin cancer screenings on preventive and risk behaviour

Aim

Skin cancer is the most prevalent cancer in western countries and is associated with a high burden of disease. Skin cancer screenings can help detect cancer at an early stage and thus allow for better treatment. We aimed to analyse the impact of workplace skin cancer screenings on prevention behaviour and potential spillover effects on non-participants.

Subject and methods

Participants of workplace skin cancer screenings completed questionnaires at 0, 3 and 12 months on knowledge about and attitudes toward skin cancer and prevention behaviours. Effects over time were compared using McNemar tests. For additional analyses we performed logistic regression analyses.

Results

Of the 998 participants (44.7% women, mean age 43.3 years), 26.7% had never attended a skin cancer screening. The proportion of participants seeking shade for UV protection and the number of visits to dermatologists and general practitioners increased significantly in the year following workplace screening (p < 0.05). Two thirds (66.4%) recommended skin cancer screenings to others and at least 39.2% of them were sure that this recommendation was followed. Characteristics associated with participants’ recommendation for screening included female gender (odds ratio: 1.62), older age (odds ratio: 1.02), and lower education (odds ratio: 1.40).

Conclusion

Workplace screenings can complement routine skin cancer screenings. They inform participants about the existence and benefits of screenings and may have spillover effects for peers. They can also serve as another source of information on prevention and risk behaviours.

"Why We Keep Coming Back": Family and Provider Perspectives on Factors Influencing Long-term Follow-up for Pediatric Cancer Survivorship Care

PURPOSE

The majority of childhood cancer survivors do not follow-up for long-term risk-based screening for recurrent illness and treatment late effects, despite a high prevalence of secondary morbidities. The primary aim of this study was to investigate factors that influence long-term follow-up for survivorship care, from the perspectives of providers, patients, and caregivers.

MATERIALS AND METHODS

A semistructured interview was designed to elicit stakeholder perspectives on factors that facilitate or impede routine clinic visits after completion of cancer therapy. Results were analyzed using a qualitative framework method.

RESULTS

Providers, patients, and caregivers identified a wide range of factors that might influence long-term follow-up for care. All respondents noted the importance of efficient clinical operations, resources such as parking, provider behaviors, rapport/attachment, and patient/family logistics. Compared with patients/caregivers, providers more frequently mentioned institutional operations, their own education and skills, patient/family understanding and motivation, and interpersonal processes such as communication style. Families more frequently mentioned clinic environment, and patients more frequently noted the importance of having a family member present, something neither providers nor caregivers reported.

CONCLUSIONS

Providers, patients, and patient caregivers have different perspectives regarding factors that may influence follow-up for long-term survivorship care. Understanding these differences can help inform efforts to improve follow-up.

Association Between Dense Breast Legislation and Cancer Stage at Diagnosis

INTRODUCTION

Many states have mandated breast density notification and insurance coverage for additional screening; yet, the association between such legislation and stage of diagnosis for breast cancer is unclear. This study investigates this association and examines the differential impacts among different age and race/ethnicity subgroups.

METHODS

The Surveillance, Epidemiology, and End Results database was queried to identify patients with breast cancer aged 40-74 years diagnosed between 2005 and 2016. Using a difference-in-differences multinomial logistic model, the odds of being diagnosed at different stages of cancer relative to the localized stage depending on legislation and individual characteristics were examined. Analyses were conducted in 2020-2021.

RESULTS

The study included 689,641 cases. Overall, the impact of notification legislation was not significant, whereas insurance coverage legislation was associated with 6% lower odds (OR=0.94, 95% CI=0.91, 0.96) of being diagnosed at the regional stage. The association between insurance coverage legislation and stage of diagnosis was even stronger among women aged 40-49 years, with 11% lower odds (OR=0.89, 95% CI=0.82, 0.96) of being diagnosed at the regional stage and 12% lower odds (OR=0.88, 95% CI=0.81, 0.96) of being diagnosed at the distant stage. Hispanic women benefited from notification laws, with 11% lower odds (OR=0.89, 95% CI=0.82, 0.97) of being diagnosed at distant stage. Neither notification nor supplemental screening insurance coverage legislation showed a substantial impact on Black women.

CONCLUSIONS

The findings imply that improving insurance coverage is more important than being notified overall. Raising awareness is important among Hispanic women; improving communication about dense breasts and access to screening might be more important than legislation among Black women.

Residential Area Sociodemographic and Breast Cancer Screening Venue Location Built Environmental Features Associated with Women's Use of Closest Venue in Greater Sydney, Australia

Understanding environmental predictors of women’s use of closest breast screening venue versus other site(s) may assist optimal venue placement. This study assessed relationships between residential-area sociodemographic measures, venue location features, and women’s use of closest versus other venues. Data of 320,672 Greater Sydney screening attendees were spatially joined to residential state suburbs (SSCs) (n = 799). SSC-level sociodemographic measures included proportions of: women speaking English at home; university-educated; full-time employed; and dwellings with motor-vehicles. A geographic information system identified each woman’s closest venue to home, and venue co-location with bus-stop, train-station, hospital, general practitioner, and shop(s). Multilevel logistic models estimated associations between environmental measures and closest venue attendance. Attendance at closest venue was 59.4%. Closest venue attendance was positively associated with SSC-level women speaking English but inversely associated with SSC-level women university-educated, full-time employed, and dwellings with motor-vehicles. Mobile venue co-location with general practitioner and shop was positively, but co-location with bus-stop and hospital was inversely associated with attendance. Attendance was positively associated with fixed venue co-location with train-station and hospital but inversely associated with venue co-location with bus-stop, general practitioner, and shop. Program planners should consider these features when optimising service locations to enhance utilisation. Some counterintuitive results necessitate additional investigation.

Understanding patient factors to increase uptake of cancer screening: a review

Early detection of cancer through organized screening is a central component of population-level strategies to reduce cancer mortality. For screening programs to be effective, it is important that those invited to screening participate. However, uptake rates are suboptimal in many populations and vary between screening programs, indicating a complex combination of patient factors that require elucidation to develop evidence-based strategies to increase participation. In this review, the authors summarize individual-level (sociodemographic and psychosocial) factors associated with cancer screening uptake and evidence for the effectiveness of behavioral interventions to increase uptake. The authors reflect on current trends and future directions for behavioral cancer screening research to overcome challenges and address unmet needs in reducing cancer mortality.

The integrated screening action model (I-SAM): A theory-based approach to inform intervention development

Screening can reduce deaths if the people invited participate. However, good uptake is hard to achieve, and our current approaches are failing to engage the most vulnerable. A coherent model of screening behaviour to guide our understanding and intervention development is yet to be established. The present aim was to propose an Integrated Screening Action Model (I-SAM) to improve screening access. The I-SAM synthesises existing models of health behaviour and empirical evidence. The I-SAM was developed following: i) an appraisal of the predominant models used within the screening literature; ii) the integration of the latest knowledge on behaviour change; with iii) the empirical literature, to inform the development of a theory-based approach to intervention development. There are three key aspects to the I-SAM: i) a sequence of stages that people pass through in engaging in screening behaviour (based on the Precaution Adoption Process Model); ii) screening behaviour is shaped by the interaction between participant and environmental influences (drawing from the Access Framework); and iii) targets for intervention should focus on the sources of behaviour - 'capability', 'opportunity', and 'motivation' (based on the COM-B Model). The I-SAM proposes an integrated model to support our understanding of screening behaviour and to identify targets for intervention. It will be an iterative process to test and refine the I-SAM and establish its value in supporting effective interventions to improve screening for all.

Personalising lung cancer screening: An overview of risk-stratification opportunities and challenges

Randomised clinical trials have shown the efficacy of computed tomography lung cancer screening, initiating discussions on whether and how to implement population‐based screening programs. Due to smoking behaviour being the primary risk‐factor for lung cancer and part of the criteria for determining screening eligibility, lung cancer screening is inherently risk‐based. In fact, the selection of high‐risk individuals has been shown to be essential in implementing lung cancer screening in a cost‐effective manner. Furthermore, studies have shown that further risk‐stratification may improve screening efficiency, allow personalisation of the screening interval and reduce health disparities. However, implementing risk‐based lung cancer screening programs also requires overcoming a number of challenges. There are indications that risk‐based approaches can negatively influence the trade‐off between individual benefits and harms if not applied thoughtfully. Large‐scale implementation of targeted, risk‐based screening programs has been limited thus far. Consequently, questions remain on how to efficiently identify and invite high‐risk individuals from the general population. Finally, while risk‐based approaches may increase screening program efficiency, efficiency should be balanced with the overall impact of the screening program. In this review, we will address the opportunities and challenges in applying risk‐stratification in different aspects of lung cancer screening programs, as well as the balance between screening program efficiency and impact.

Factors Explaining Socio-Economic Inequalities in Cancer Survival: A Systematic Review

BACKGROUND

There is strong and well-documented evidence that socio-economic inequality in cancer survival exists within and between countries, but the underlying causes of these differences are not well understood.

METHODS

We systematically searched the Ovid Medline, EMBASE, and CINAHL databases up to 31 May 2020. Observational studies exploring pathways by which socio-economic position (SEP) might causally influence cancer survival were included.

RESULTS

We found 74 eligible articles published between 2005 and 2020. Cancer stage, other tumor characteristics, health-related lifestyle behaviors, co-morbidities and treatment were reported as key contributing factors, although the potential mediating effect of these factors varied across cancer sites. For common cancers such as breast and prostate cancer, stage of disease was generally cited as the primary explanatory factor, while co-morbid conditions and treatment were also reported to contribute to lower survival for more disadvantaged cases. In contrast, for colorectal cancer, most studies found that stage did not explain the observed differences in survival by SEP. For lung cancer, inequalities in survival appear to be partly explained by receipt of treatment and co-morbidities.

CONCLUSIONS

Most studies compared regression models with and without adjusting for potential mediators; this method has several limitations in the presence of multiple mediators that could result in biased estimates of mediating effects and invalid conclusions. It is therefore essential that future studies apply modern methods of causal mediation analysis to accurately estimate the contribution of potential explanatory factors for these inequalities, which may translate into effective interventions to improve survival for disadvantaged cancer patients.

The role of residential history in cancer research: A scoping review

The role of residential history in cancer prevention, diagnosis, treatment, and survivorship is garnering increasing attention in cancer research. To our knowledge, there is no comprehensive synthesis of the current state of knowledge in the field. We reviewed the extant literature on this topic and conducted a scoping analysis to examine two main research questions: (a) To what degree, and how, have researchers accounted for residential history/mobility in cancer research? and (b) What are the gaps in the literature based on a knowledge synthesis using scoping review and concept mapping? To answer these questions, this scoping analysis focuses on how researchers compile, analyze and discuss residential history/mobility in studies on cancer. The study is focused on peer-reviewed articles from 6 different datasets (PubMed, Cinahl, Scopus, Web of Science and JSTOR, ERIC) from 1990 to August 2020. The review captured 1951 results in total, which was scoped to 281 relevant peer-reviewed journal articles. First, we examined these articles based on cancer continuum, cancer type and the main theme. Second, we identified 21 main themes and an additional 16 sub-themes in the pool of the selected articles. We utilized concept mapping to provide a conceptual framework and to highlight the underlying socioecological assumptions and paradigms. Results show that cancer research incorporating residential histories is primarily focused on incidence and estimating cumulative exposure, with little consideration across the cancer continuum. Additionally, our review suggests that although the social environment plays an important role across the cancer continuum, a small number of articles were focused on such factors and this area remains relatively unexplored. Additionally, the expansion of interdisciplinary research on residential mobility before and after cancer diagnosis will enhance understanding of the role of environmental and socioeconomic characteristics and exposures on cancer continuum.

An Urban Center Experience Exploring Barriers to Adherence to Endoscopic Surveillance for Non-Dysplastic Barrett's Esophagus

Background

Data regarding barriers to Barrett’s esophagus (BE) surveillance is limited. Studying an urban center population, we aimed to characterize non-dysplastic BE surveillance rates and identify health, racial, and socioeconomic disparities affecting surveillance.

Methods

Patients with biopsy-confirmed BE were retrospectively identified between January 2002 and December 2012. Non-dysplastic BE patients were analyzed for adherence to established surveillance guidelines. Demographic, racial, comorbidities, and socioeconomic variables were extracted. Annual gross income (AGI) was utilized as a marker of socioeconomic status (SES). Univariate and multivariate analyses compared adherent vs. non-adherent patients to surveillance guidelines.

Results

A total of 217 patients with non-dysplastic BE were analyzed. The majority were male (67.3%) and Caucasian (75.6%), with only 47.5% adherent with the first surveillance endoscopy. Patients with a high average AGI were more likely to be adherent with the initial surveillance endoscopy than those with low AGI (p=0.032). Initial compliance with first surveillance was associated with better surveillance at regular intervals (p=0.001). No significant differences in age, primary language, insurance type, marital status, or Charlson Comorbidity Index (CCI) between adherent and non-adherent patients were found.

Conclusions

Although overall adherence to guidelines was suboptimal, this study identifies important socioeconomic disparities in the endoscopic surveillance for non-dysplastic BE. Identifying and understanding the barriers to care among these lower socioeconomic groups may ultimately lead to improved screening compliance and early BE detection.

Smartphone education improves embarrassment, bowel preparation, and satisfaction with care in patients receiving colonoscopy: A randomized controlled trail

BACKGROUND

Colonoscopy is considered a safe and effective tool for detecting colorectal cancer. Nevertheless, the proportion of patients are hesitating to receive colonoscopy. Smartphone education may decrease the barrier of colonoscopy. The aim of this study is to examine the effectiveness of smartphone education in colonoscopy.

METHODS

We conducted a prospective, double-blinded, randomized, controlled study to examine the effectiveness of smartphone education on embarrassment, bowel preparation, and satisfaction in colonoscopy. The patients' embarrassment was measured by the colonoscopy embarrassment scale. The quality of the bowel preparation was evaluated by gastroenterologists according to the Aronchik Scale. The satisfaction of colonoscopy care was assessed by a satisfaction scale developed by the authors.

RESULTS

A total of 150 patients were analyzed in the smartphone education and control groups (n = 75 in each group). The smartphone education group reported fewer embarrassment (B = -2.78, P = .02) than those of the control group, the patients who were older (B = .15, P = .001) and who were male (B = 2.91, P = .003) showed higher embarrassment. Additionally, smartphone education group were likely to have better colon preparation (odds ratio = 2.46, 95% confidence interval: 1.20-5.02) than that of the control group. Smartphone education also improved the satisfaction with care (β = 4.60, P < .001), and above normal body mass index decreased the satisfaction with care (β = -0.19, P < .05).

CONCLUSION

Smartphone education improves embarrassment, bowel preparation, and satisfaction with care in patients receiving colonoscopy.

Does the Flemish colorectal cancer screening programme reach equity in FIT uptake?

BACKGROUND

To investigate colorectal cancer (CRC) screening rates by the faecal immunochemical test (FIT) according to sociodemographic characteristics and nationality.

METHODS

Men and women, aged 56-74, invited to participate in the Flemish CRC screening programme in 2013 and 2014 were included in this study. We analysed the association between CRC screening uptake and sex, age, (first and current) nationality and several proxies for socio-economic status (SES). The statistical analysis was based on descriptive analyses and logistic regression models.

RESULTS

A total of 1 184 426 persons were included in our analysis. The overall screening uptake was 52.3%, uptake varied by sex, age, nationality and SES. Lower participation rates were associated with the youngest and oldest age categories (56-60 and 70-74) and being male. All nationalities other than Belgian or Dutch were significantly less screened. Lower uptake of screening was also associated with several proxy's for low SES, such as having an allowance for being disabled, not being able to work, being an extended minor and having a social allowance/minimum wage. The descriptive analysis showed a 27% difference in CRC screening uptake between the (early) retired and the people entitled to a minimum wage.

CONCLUSIONS

There is a significant difference between screening uptake and demographic and socio-economic variables in the first 2 years of the population-based screening programme in Flanders. Based on the study results, implementing strategies to improve participation in those subgroups is needed.

Negative cancer beliefs: Socioeconomic differences from the awareness and beliefs about cancer survey

OBJECTIVE

Socioeconomic gaps in cancer mortality may be driven partially by poorer uptake of early detection behaviors among lower socioeconomic status (SES) groups. Lower SES groups may hold both fewer positive and more negative cancer beliefs that discourage these behaviors. We examined SES differences in positive and negative cancer beliefs in US adults.

METHODS

We conducted telephone interviews with a population-representative sample, aged 50+, using the Awareness and Beliefs about Cancer instrument (N = 1425). Cancer beliefs were measured using three positively and three negatively framed items. We used multivariable logistic regression models to examine associations between beliefs and education, which served as a marker of individual-level SES.

RESULTS

Agreement with positive statements was high (>80%) and did not vary with education, while agreement with negative statements varied. Relative to adults with a bachelor's degree, adults with a high school degree or less were more likely to agree that "treatment is worse than cancer" (45.2% vs. 68.2%; adjusted odds ratio (aOR) = 2.43, 99% CI = 1.50-3.94), cancer is "a death sentence" (17.4% vs. 33.2%; aOR = 2.51, 99% CI = 1.45-4.37), and they "would not want to know if I have cancer" (15.7% vs. 31.6%; aOR = 2.88, 99% CI = 1.54-5.36).

CONCLUSIONS

Positive cancer statements were generally endorsed, but negative statements were more frequently endorsed by lower SES groups. Additional work is needed to understand how negative beliefs develop and coexist alongside positive beliefs. Interventions to improve detection behaviors targeting lower SES groups may benefit from focusing on reducing negative beliefs, rather than increasing positive beliefs.

Awareness of alcohol as a risk factor for cancer: A population-based cross-sectional study among 3000 Danish men and women

Alcohol increases the risk of several cancer types. However, awareness of the link between alcohol and cancer is estimated to be low in Denmark. The objective of this study was to examine awareness of alcohol as a risk factor for cancer in the Danish population. 3000 Danish men and women aged 18–74 years, who are nationally representative participated in a cross-sectional study. Open and closed-ended questions were used to assess unprompted and prompted cancer awareness in relation to the respondents’ demographic profile, alcohol consumption and use of tobacco.

Unprompted, 22.2% of respondents were aware of the link between alcohol and cancer, whereas prompted 44.8% were aware of this. When prompted about specific cancer types, 39.5% were aware of the fact that alcohol increases the risk of liver cancer and only 9.6% were aware of the link between alcohol and breast cancer. Being aware of the link between alcohol and cancer was associated with being female, having a higher level of education, living in the Capital Region of Denmark, as well as being a non-smoker. There were no statistical significant associations between awareness of alcohol as a risk factor for cancer and the respondents’ age, marital status and alcohol consumption.

Conclusively, the study confirms a rather low public awareness of the link between alcohol and cancer in the Danish population, especially regarding certain cancer types such as breast cancer. There is a continued need to inform the public about the relationship between alcohol and cancer.

The impact of socioeconomic deprivation on the uptake of colorectal cancer screening in London

OBJECTIVE

Screening programmes based on the faecal occult blood test (FOBT) can reduce mortality from colorectal cancer (CRC). However, a significant variation exists in uptake of the test within the UK. Disproportionate uptake risks increasing inequity during staging at diagnosis and survival from CRC. This study aims to evaluate the impact of socioeconomic deprivation on the uptake of CRC screening (FOBT) in London.

METHODS

A retrospective review of the "Vanguard RM Informatics" database was performed to identify eligible individuals for CRC screening across all general practices across London over 30 months (2014-2017). The postcodes of the general practices were used to obtain the deprivation data via the "Indices of Deprivation" database. A Spearman's rho correlation was performed to quantify the impact of the deprivation variables on FOBT uptake.

RESULTS

Overall, 697,402 individuals were eligible for screening across 1359 London general practices, within 5 Clinical Commissioning Groups (CCGs); 48.4% (range: 13%-74%) participated in CRC screening with the lowest participation rates in North West (46%) and North East (47%) London CCGs. All indices of deprivation had a significant correlation with the uptake of FOBT (p < 0.01).

CONCLUSION

This is the largest study across London to date demonstrating a significant positive correlation between deprivation indices and FOBT uptake, highlighting areas of particular risk. Further studies are imperative to quantify the impact of deprivation on CRC morbidity and mortality, together with focused strategies to reduce socioeconomic inequalities in screening in these high risk areas.

Physical Activity in Peri-Urban Communities: Testing Intentional and Implicit Processes within an Ecological Framework

BACKGROUND

Given the substantive health inequalities in peri-urban communities and the potential for physical activity to promote health in these communities, identifying modifiable physical activity determinants in this population is important. This study explored effects of the peri-urban environment and psychological constructs on physical activity intentions and behavioural automaticity guided by an integrated theoretical framework.

METHODS

Peri-urban Australians (N = 271) completed self-report measures of environmental (i.e. physical/social environment, and neighbourhood selection), motivational (i.e. autonomous motivation), and social cognition (i.e. attitudes, norms, and perceived behavioural control [PBC]) constructs, past behaviour, intentions, and automaticity.

RESULTS

A well-fitting path analytic model revealed that: autonomous motivation predicted all social cognition constructs; subjective norms and PBC, but not attitudes; autonomous motivation predicted intentions and automaticity; and subjective norms and PBC mediated effects of autonomous motivation on intentions. Of the environmental constructs, only neighbourhood selection was related to intentions, mediated by PBC.

CONCLUSIONS

Autonomous motivation is an important correlate of physical activity intentions and automaticity, and subjective norms and PBC also related to intentions. Individuals perceiving a supportive environment were more likely to report positive PBC and intentions. Targeting change in autonomous motivation, and normative and control beliefs may help enhance physical activity intentions and automaticity in peri-urban communities.

Assessing Physical Activity Behavior of Cancer Survivors by Race and Social Determinants of Health

Introduction:

Black cancer survivors remain at a higher risk for secondary cancers, cancer recurrence, and comorbid conditions than non-Hispanic White survivors. Physical activity may help improve health outcomes and overall quality of life. We assessed cancer survivors’ physical activity by race/ethnicity and the effect of social determinants of health (SDH) constructs (i.e., economic stability, education, and access to health care) on physical activity.

Methods:

This was a cross-sectional analysis of data from the 2016 Behavioral Risk Factor Surveillance System. The outcome variable was physical activity after cancer diagnosis and the predictor variables were SDH and race. Multivariable logistic regressions were used to examine associations between race and physical activity and the effect of SDH on physical activity.

Results:

Among 3,787 cancer survivors, 91.6% self-identified as White and 8.4% as Black. Blacks were more likely than Whites to report low economic stability, low access to health care, and low health literacy (all p s < .01). Blacks were less likely than Whites to engage in physical activity after controlling for demographic and clinical factors (adjusted odds ratio [ORAdj] = 0.71; 95% confidence interval [CI] = 0.56–0.91; p = .01) and after additional adjustment of SDH (ORAdj = 0.77; 95% CI = 0.60–0.99; p = .04).

Conclusions:

The findings suggest that though Black cancer survivors are less than White to engage in physical activity, and SDH partially explained the racial difference in physical activity behaviors. These findings highlight the need to address barriers to health-care access, economic stability, and educational attainment.

Link between prostate cancer diagnosis and stroke in the United States during 2007-2017

Introduction

The main purpose of this work is to study prostate cancer and stroke in the United States during the years 2007-2017 and to find not only statistically significant predictors for cancer, but also a possible association between prostate cancer and stroke.

Material and methods

The statistical methods used to derive the results of this work are χ² test and one-way analysis of variance (ANOVA), in order to check the statistical significance of prostate cancer in relation to socio-economic factors of patients. In addition, a multivariate logistic regression analysis was used with the odds ratio (OR) to find statistically significant prognostic factors for both prostate cancer and stroke.

Results

According to multiple logistic regression analysis, males who are unemployed but have worked previously have 16 times higher risk of developing prostate cancer, while widowed men have five times higher risk for the occurrence of this type of cancer. In addition, marital status and employment proved to be also prognostic risk factors for stroke.

Conclusions

Our results describe for the first time the importance of deprivation (of work and partner) as a primary prognostic risk factor for cancer. Moreover, the same factor proved to be the primary prognostic risk factor for stroke as well as for prostate cancer, a fact that implies a possible link between cancer and stroke.

Perceived Neighborhood Environment and Its Association with Health Screening and Exercise Participation amongst Low-Income Public Rental Flat Residents in Singapore

Background: In Singapore, an Asian city-state, more than 80% live in public housing. While the majority (90%) own their homes, a needy minority lives in rental flats. Public rental flats are built in the same location as owner-occupied blocks. We evaluated factors associated with perceptions of the neighborhood environment and its association with exercise and health screening participation. Methods: Logistic regression was used to identify associations between perceptions of the neighborhood environment (overall perceived neighborhood disadvantage, safety, and convenience) and sociodemographic factors, as well as exercise and screening participation, amongst residents aged ≥60 years in two Singaporean public housing precincts in 2016. Results: Our response rate was 62.1% (528/800). Staying in a rental flat independently was associated with increased neighborhood disadvantage (adjusted odds ratio, aOR = 1.58, 95%CI = 1.06⁻2.35). Staying in a stand-alone block (as opposed to staying in a mixed block comprised of both rental and owner-occupied units) was associated with perceptions of a poorer physical environment (aOR = 1.81, 95%CI = 1.22⁻2.68) and lower perceived proximity to recreational areas (aOR = 1.14, 95%CI = 1.04⁻1.25). Perceptions of neighborhood disadvantage were independently associated with reduced exercise participation (aOR = 0.67, 95%CI = 0.45⁻0.98) and reduced participation in diabetes screening (aOR = 0.63, 95%CI = 0.41⁻0.95). Conclusion: Despite sharing the same built environment, differences in the perception of the neighborhood environment between low-socioeconomic status (SES) and high-SES communities persist. Perceived neighborhood disadvantage is associated with lower participation in regular exercise and diabetes screening.

Are smokers less likely to seek preventive healthcare measures in Italy?

Smoking cessation is the key cancer and cardiovascular disease (CVD) prevention action for smokers; however, smokers can still benefit from earlier diagnosis. This study aims to investigate behaviours towards cancer and CVD prevention by smoking habits in Italy. The study relies on data from a large Italian population-based survey carried out in 2013 on a sample of 119 073 individuals. We studied the relationship between smoking habits and the participation in cancer (cervical, breast and colorectal) screening programmes, or CVD prevention (performing cholesterol, blood pressure and glycaemia exams) using a multilevel logistic regression model. Only 11.4, 40.1 and 8.0% of the subsamples attended cervical, breast and colorectal cancer screening, respectively, whereas CVD prevention registered higher attendance: 83.3, 66.4 and 58.1%, respectively, for cholesterol, blood pressure and glycaemia. Smokers were less likely to undergo Pap smear compared with nonsmokers [odds ratio (OR): 0.70; 95% confidence interval (CI): 0.57-0.87], whereas former smokers showed a higher attendance for breast and colorectal cancer screening (OR: 1.25; 95% CI: 1.14-1.37 for breast, OR: 1.21; 95% CI: 1.07-1.38 for colorectal cancer). Former smokers were also more likely to perform CVD prevention. Moreover, CVD prevention was inversely related to smoking (OR: 0.84; 95% CI: 0.74-0.96 for cholesterol; OR: 0.86; 95% CI: 0.79-0.93 for blood pressure; OR: 0.61; 95% CI: 0.54-0.69 for glycaemia). Particular attention should be paid to involve smokers in prevention checks. Research aimed at understanding smokers' pessimistic attitudes, which may determine smokers' prevention avoidance, and at improving smokers' engagement with prevention is needed and may help increase the reach of supported smoking-cessation programmes.

Two-month follow-up evaluation of a cancer awareness training workshop ("Talk Cancer") on cancer awareness, beliefs and confidence of front-line public health staff and volunteers

People working across the health service, local government, community and voluntary sectors are appropriately placed to have discussions about cancer prevention and early diagnosis with members of the public. Cancer Research UK's training workshop ("Talk Cancer") aims to increase awareness of cancer screening programmes and risk factors, promote more positive beliefs about cancer and increase confidence to discuss cancer with members of the public, among people working in these roles. This study evaluated "Talk Cancer" by surveying 178 trainees immediately before, immediately after, and two months after training in the United Kingdom. Results showed that "Talk Cancer" was effective at promoting and maintaining more positive beliefs about cancer and confidence to discuss cancer. While there was an improvement in awareness of risk factors immediately after the workshop, there was less evidence that this was maintained at two-months, but awareness was improved relative to baseline in most cases. Increased awareness of the national bowel screening programme was maintained at two-months. While awareness that screening programmes do not exist for oral, skin and prostate cancers was not maintained, awareness was higher than baseline. The majority of trainees (86%) indicated they had applied their learning in their role and 59% reported having had more conversations about cancer prevention and early diagnosis since training. The impact of "Talk Cancer" on trainees' beliefs and confidence persists beyond the workshop, however, ongoing support is required to maintain improvements in awareness of cancer risk factors and which cancer types do not have national screening programmes.

Direct notification of cervical cytology results to women improves follow-up in cervical cancer screening - A cluster-randomised trial

Up to half of all women do not receive follow-up as recommended after cervical cytology testing and are thus at increased risk of dysplasia progression. Women from lower social positions are at increased risk of not receiving follow-up. Sample takers, often general practitioners, convey results to women, but communication problems constitute a challenge. We aimed to investigate the effect of direct notification of cervical cytology results on follow-up rates. In a 1:1 cluster-randomised controlled trial, we assessed if having the pathology department convey cervical cytology results directly to the investigated women improved timely follow-up, compared with conveying the results via the general practitioner as usual. All women with a cervical cytology performed in a general practice in the Central Denmark Region (2013-2014) and receiving follow-up recommendation were included (n = 11,833). The proportion of women without timely follow-up was lower in the group with direct notifications than in the control group of women receiving usual care, regardless of age, educational status, cohabitation status and ethnicity. Among the women with the most severe cervical cytology diagnoses who are recommended gynaecological follow-up within 3 months, the percentage without timely follow-up was 15.1% in the intervention group and 19.5% in the control group (prevalence difference: -0.04 (95%CI: -0.07; -0.02)). Improved timely follow-up was also observed for women with a recommendation to have follow-up performed at 3 and 12 months. Cervical cytology results conveyed directly by letter to women increased the proportion of women with timely follow-up without raising inequality in follow-up measured by social position. Trial registration: ClinicalTrials.gov (TRN: NCT02002468) 29 November 2013.

Organised population-based programmes and change in socioeconomic inequalities in mammography screening: A 1992-2012 nationwide quasi-experimental study

Organised mammography screening programmes may reduce socioeconomic inequalities in breast cancer screening, but evidence is contradictory. Switzerland has no national organised mammography screening programme, but regional programmes were progressively introduced since 1999, giving the opportunity to conduct a nationwide quasi-experimental study. We examined the evolution of socioeconomic inequalities in mammography screening in Switzerland and if exposure to regional organised programmes reduced socioeconomic inequalities. Data of 10,927 women aged 50 to 70 years old were collected from the Swiss Health Interview Survey, a nationally representative cross-sectional survey repeated 5 times (1992-2012). Socioeconomic characteristics were assessed using education, income, employment status, and occupational class. Adjusted prevalence ratios of up-to-date mammography screening were estimated with Poisson regressions and weighted for sampling strategy and non-participation bias. In the absence of organised screening programmes (1992-1997), prevalence of mammography screening increased by 23% and was associated with tertiary education and working part time. During the period of progressive introduction of regionally organised programmes (2002-2012), prevalence of mammography screening increased by 19% every 5 years and was associated with exposure to regional programmes and with independent/artisan occupations. Tertiary education and working part time were no longer associated. Exposure to organised programmes did not modify socioeconomic inequalities except for employment status: not employed women benefitted more from organised programmes compared to women working full time. In conclusion, socioeconomic inequalities in mammography screening decreased over time but organised programmes did not greatly modify them, except women not employed whose prevalence passed employed women.

Towards Health Equity: Deaf Adults' Engagement in Social e-Health Activities and e-Communication with Health Care Providers

Deaf people face significant barriers with accessing health information, health care services, and communication with their health care provider and as a result, show poorer health outcomes compared to the general population. Studies on the general population found that those who use social network sites (SNS) for health-related activities were more likely to communicate with their health care provider via the Internet or email. For deaf individuals who use American Sign Language (ASL), using eHealth platforms to communicate with health care providers has the potential to navigate around communication barriers and create greater opportunity to discuss screening and treatment plans. Using national data from the HINTS-ASL survey, we explored whether engagement in social eHealth activities on SNS is linked to electronic communication with health care providers after controlling for deaf patient characteristics. Our sample for this study consisted of 515 deaf participants who reported using (social media/SNS) to read and share health information. Controlling for sociodemographic variables, participants who engaged in social eHealth activity were threefold more likely to communicate with their healthcare provider electronically. Using eHealth platforms for social health engagement demonstrates potential to reduce health inequality among deaf people.

Emotional predictors of bowel screening: the avoidance-promoting role of fear, embarrassment, and disgust

Background

Despite considerable efforts to address practical barriers, colorectal cancer screening numbers are often low. People do not always act rationally, and investigating emotions may offer insight into the avoidance of screening. The current work assessed whether fear, embarrassment, and disgust predicted colorectal cancer screening avoidance.

Methods

A community sample (N = 306) aged 45+ completed a questionnaire assessing colorectal cancer screening history and the extent that perceptions of cancer risk, colorectal cancer knowledge, doctor discussions, and a specifically developed scale, the Emotional Barriers to Bowel Screening (EBBS), were associated with previous screening behaviours and anticipated bowel health decision-making.

Results

Step-wise logistic regression models revealed that a decision to delay seeking healthcare in the hypothetical presence of bowel symptoms was less likely in people who had discussed risk with their doctor, whereas greater colorectal cancer knowledge and greater fear of a negative outcome predicted greater likelihood of delay. Having previously provided a faecal sample was predicted by discussions about risk with a doctor, older age, and greater embarrassment, whereas perceptions of lower risk predicted a lower likelihood. Likewise, greater insertion disgust predicted a lower likelihood of having had an invasive bowel screening test in the previous 5 years.

Conclusions

Alongside medical and demographic factors, fear, embarrassment and disgust are worthy of consideration in colorectal cancer screening. Understanding how specific emotions impact screening decisions and behaviour is an important direction for future work and has potential to inform screening development and communications in bowel health.

Decision-making and socioeconomic disparities in colonoscopy screening in African Americans

BACKGROUND

Socioeconomic status (SES) disparities in colorectal cancer screening are persistent. Lower education and income are both associated with lower screening rates. Both cognitive (e.g., perceived barriers) and affective (e.g., disgust, fear) decision-making constructs are known determinants of colorectal cancer screening behavior. This study tests the hypotheses that SES may be related to decision-making constructs and that this SES-decision-making construct relation may contribute to explaining the SES-screening behavior disparity.

METHOD

Surveys assessing perceived benefits and barriers to screening, self-efficacy, positive and negative affective associations with colonoscopy, fear of colonoscopy, colorectal cancer knowledge, past screening behavior, and demographics including education and income were completed by 2,015 African American participants ages 50 and older. Both univariable and multivariable relations of SES to decision-making constructs were examined, as were univariable and multivariable models of the indirect effect of SES on screening via decision-making constructs.

RESULTS

Socioeconomic status was related to both screening compliance and the decision-making constructs. Bootstrap modeling of the indirect effect showed that the total effect of the SES-screening behavior relation included an indirect effect via social cognitive decision-making constructs.

CONCLUSION

These findings suggest that cognitive and affective decision-making constructs account for at least some of the SES disparities in colorectal cancer screening behavior. As such, more research is needed to explore the intra individual-level influences of disparities in colorectal cancer screening. In addition, work is needed to develop effective intervention approaches to address the relation of SES to decision-making constructs. (PsycINFO Database Record
