Changes in colorectal cancer knowledge and screening intention among Ohio African American and Appalachian participants: The screen to save initiative

Educational interventions to improve bowel cancer awareness and screening in Organisation for Economic Co-operation and Development countries: A scoping review

Objectives

Summarise theory informed educational interventions for improving bowel cancer awareness and screening.

Methods

A search was conducted in PubMed, EMBASE, Web of Science and CINAHL. English studies from 2016 to 2022 which implemented community-based bowel cancer awareness and/or screening education interventions for adults in Organisation for Economic Co-operation and Development countries were included.

Results

Sixty-two studies were included, 32 measured both screening and awareness (24 measured screening only, 6 measured awareness only). Education interventions were grouped and summarised in five education types: lay community health education/counselling (n = 28), education material (n = 5), health professional education/counselling (n = 10), mass media (n = 5) and other (n = 19). Other included education interventions which did not fit into the four types previously mentioned. Six studies tested more than one education type. Each type within these studies were reported/summarised separately within the appropriate education type. Lay educators resulted in improved awareness and screening. Brochures were effective education materials for screening and combined with lay educators resulted in increased awareness. State-wide mass media campaigns significantly improved screening uptake for up to 2-months post-campaign. Fear and loss-framed messaging improved screening intentions compared to humour or gain-based messaging. Decision aids had limited improvements in awareness. Facebook campaign and telephone counselling had limited improvements in screening.

Conclusions

Lay community health educators, brochures, and mass media campaigns occurring multiple times a year may be effective interventions in improving screening and/or awareness. Such approaches should be considered when developing community education. Education interventions should include multiple components suggested above to maximise improvements of awareness and screening.

Structural enrichment attenuates colitis-associated colon cancer

Colorectal cancer (CRC) is a major public health concern and disproportionately impacts racial/ethnic minority populations in the US. Animal models are helpful in examining human health disparities because many stress-induced human health conditions can be recapitulated using mouse models. Azoxymethane (AOM)/ dextran sodium sulfate (DSS) treatment can be used to model colitis-associated cancers. While colitis-associated cancers account for only 2% of colon cancers, the AOM/DSS model is useful for examining links between inflammation, immunity, and colon cancer. Mice were housed in enriched and impoverished environments for 1-month prior to behavioral testing. Following behavioral testing the mice were subjected to the AOM/DSS model. While our analysis revealed no significant behavioral variances between the impoverished and enriched housing conditions, we found significant effects in tumorigenesis. Enriched mice had fewer tumors and smaller tumor volumes compared to impoverished mice. African Americans are at higher risk for early onset colorectal cancers in part due to social economic status. Furthermore, housing conditions and environment may reflect social economic status. Research aimed at understanding links between social economic status and colorectal cancer progression is important for eliminating disparities in health outcomes.

Assessing and Addressing the Determinants of Appalachian Population Health: A Scoping Review

Introduction

Residents of Appalachia experience elevated rates of morbidity and mortality compared to national averages, and these disparities are associated with inequitable exposures to various determinants of population health. Social and environmental determinants of health are a useful lens through which to develop and evaluate programs to mitigate regional health disparities.

Methods

This 2023 scoping review was conducted of studies linking determinants of Appalachian health with leading causes of regional mortality and morbidity. The search strategy employed a keyword search that included geographic terms for the Appalachian Region and the primary adverse health outcomes in that region. Studies meeting the following inclusion criteria were reviewed: original article, published in the last five years, involving an Appalachian population, and includes a rigorous assessment of an association between a population health determinant and one or more leading causes of Appalachian morbidity and mortality.

Results

The search returned 221 research articles, including 30 interventional studies. The top three health outcomes included cancer (43.59%), diseases of despair (23.08%), and diabetes (12.82). Access to care (27.3%), rurality (18.9%), and education (14.8%) were the most common population health determinants identified. Interventional studies were categorized by program types: education, technology, partnerships, and multilevel interventions. Due to the heterogeneity of study types, the studies were combined using a narrative synthesis.

Implications

The results of this work can inform the development and evaluation of additional programs to promote Appalachian population health. Our study team will use these results to inform community-based discussions that develop strategic plans to mitigate health disparities in Central and Southcentral Appalachian Virginia.

Barriers and facilitators of colorectal cancer screening using the 5As framework: A systematic review of US studies

Despite clear evidence that regular screening reduces colorectal cancer (CRC) mortality and the availability of multiple effective screening options, CRC screening continues to be underutilized in the US. A systematic literature search of four databases - Ovid, Medline, EBSCHOhost, and Web of Science - was conducted to identify US studies published after 2017 that reported on barriers and facilitators to CRC screening adherence. Articles were extracted to categorize relevant CRC screening barriers or facilitators that were assessed against CRC screening outcomes using the 5As dimensions: Access, Affordability, Acceptance, Awareness, Activation. Sixty-one studies were included. Fifty determinants of screening within the 5As framework and two additional dimensions including Sociodemographics and Health Status were identified. The Sociodemographics, Access, and Affordability dimensions had the greatest number of studies included. The most common factor in the Access dimension was contact with healthcare systems, within the Affordability dimension was insurance, within the Awareness dimension was knowledge CRC screening, within the Acceptance dimension was health beliefs, within the Activation dimension was prompts and reminders, within the Sociodemographics dimension was race/ethnicity, and among the Health Status dimension was chronic disease history. Among all studies, contact with healthcare systems, insurance, race/ethnicity, age, and education were the most common factors identified. CRC screening barriers and facilitators were identified across individual, clinical, and sociocontextual levels. Interventions that consider multilevel strategies will most effectively increase CRC screening adherence.

Colorectal Cancer and Its Screening Among Public in the Western Region of Saudi Arabia

Background: Colorectal cancer (CRC) is defined as a cancer that starts in the colon or the rectum. CRC is the most commonly diagnosed cancer among Saudi males and ranks third in female individuals. Awareness among the population about CRC symptoms, risk factors, and screening tests is essential for preventing further morbidity and mortality. This study aimed to assess CRC knowledge in the western region of Saudi Arabia, as well as awareness of CRC risk factors, symptoms, and screening based on various demographic data.

Methods: We conducted a cross-sectional study with a representative random sample of 358 Saudi residents in the western region. A self-administered questionnaire was distributed through social media sites starting from October 2021 till December 2021. Participants' awareness of CRC risk factors, symptoms, and screening was assessed using the questionnaire. For data analysis, we used SPSS Statistics, version 24 (IBM Corp., Armonk, NY).

Results: Of the 385 participants, 76.4% were females, and most participants had a university degree level of education. Study respondents reported fear of colonoscopy as the top reason why they avoided CRC screening. Most participants (63.4%) showed insufficient knowledge. Certain factors showed a significant association with the participants' knowledge about CRC, such as age (p<.001), higher education (p=.002), and having a career in health care (p=.002).

Conclusion: As the study resulted in overall insufficient knowledge about CRC among respondents, certain factors showed a significant association with the knowledge level. Raising awareness and health promotion programs should target older age groups and those with below university degree level of education to ultimately prevent morbidity and mortality related to colorectal cancer.

Knowledge and awareness of colorectal cancer risk factors, screening, and associated factors in advanced colorectal cancer patients: a multicenter cross-sectional study in China

Background

Colorectal cancer (CRC) is the 3rd most common malignancy globally, and its disease burden is increasing rapidly in China. But CRC patients' knowledge and awareness of CRC have not yet been examined, which could facilitate the identification of targeted population from public for intervention.

Methods

A nationwide multicenter cross-sectional survey was conducted in 19 tertiary hospitals (10 cancer hospitals and 9 general hospitals) from March 2020 to March 2021 in China. During study period, all Stage III and IV CRC patients were invited to complete a semi-structured survey that had been designed to collect information about their socio-demographic characteristics, and knowledge and awareness of CRC risk factors and screening. A multivariate logistic regression model was used to identify factors associated with their knowledge and awareness.

Results

In total, 4,589 advanced CRC patients were enrolled in this study, of whom, 46.2% were from tertiary cancer hospitals, and 59.5% were male. Patients had a mean age of 60.1±11.6 years. Before diagnosis, 65.1% of the patients had no related knowledge of the CRC risk factors, and 84.9% were unaware of the CRC screening-related information. Only 30.4% of patients had actively sought to acquire CRC-related knowledge before diagnosis. The 3 most common knowledge sources were relatives or friends who had been diagnosed with CRC (13.2%), popular science television/broadcast shows (12.9%), and community publicity and education (9.6%). Generally, knowledge and awareness were positively associated with better education level [odds ratios (ORs) ranged from 1.49 to 2.54, P<0.001], annual household income ranged from 50,000 Chinese Yuan (CNY) to 100,000 CNY (OR =1.32, P<0.001), being manual laborer (OR =1.25, P<0.001) and being white-collar worker (OR =1.47, P<0.001).

Conclusions

Advanced CRC patients' knowledge and awareness of CRC were severely limited before diagnosis. Thus, those who had limited knowledge and awareness should has a priority for intervention.

Assessing the effectiveness of a community health advisor plus screen to save educational intervention on stool-based testing adherence in an African American safety net clinic population: study protocol for a randomized pragmatic trial

Background

Colorectal cancer (CRC) is the second most deadly cancer affecting US adults and is also one of the most treatable cancers when detected at an earlier clinical stage of disease through screening. CRC health disparities experienced by African Americans are due in part to the later stage of diagnosis, suggesting the importance of improving African Americans’ CRC screening participation. The national Screen to Save (S2S) initiative employs a community health educator to deliver CRC screening education which can be tailored for specific populations, and such approaches have increased CRC screening rates in disadvantaged and racial/ethnic minority populations.

Methods/design

In this trial emphasizing stool-based CRC screening, focus groups informed the development of an adapted S2S video and brochure tailored for African Americans and identified preferred motivational text messages for a multicomponent community health advisor (CHA) intervention. A CHA hired from the community was trained to deliver a 6-week CRC educational intervention consisting of an initial face-to-face meeting followed by 5 weeks of calls and texts. Interested eligible persons are enrolled primarily through recruitment by two partnering community health centers (CHCs) and secondarily through various outreach channels and, after consenting and completing a baseline survey, are randomly assigned to one of two study arms. The CHCs are blinded to study arm assignment. Intervention arm participants receive the brochure and CHA intervention while participants assigned to the control group receive only the brochure. All participants receive a stool-based CRC screening test from their health center, and the primary outcome is the completion of the screening test at 12 months. Secondary objectives are to estimate the effect of the intervention on mediating factors, explore the effect of moderating factors, and perform a cost-effectiveness analysis of the CHA intervention.

Discussion

The TUNE-UP study will enhance understanding about CRC screening in African Americans obtaining primary health care through CHCs and is one of the very few studies to examine a CHA intervention in this context. A better understanding of the mechanisms by which the intervention affects patient beliefs and behaviors will help focus future research while the exploratory cost-effectiveness analysis will inform CHCs’ decision-making about implementing a CHA program to increase screening and reduce cancer health disparities.

Adaptation of a Community Health Advisor Intervention to Increase Colorectal Cancer Screening Among African Americans in the Southern United States

Community health advisor (CHA) interventions increase colorectal cancer (CRC) screening rates. African Americans experience CRC disparities in incidence and mortality rates compared to whites in the US. Focus groups and learner verification were used to adapt National Cancer Institute CRC screening educational materials for delivery by a CHA to African American community health center patients. Such academic-community collaboration improves adoption of evidence-based interventions. This short article describes the adaptation of an evidence-based cancer education intervention for implementation in an African American community.
