Determinants of Cancer Screening Disparities Among Asian Americans: A Systematic Review of Public Health Surveys

Equity and Opportunities in Lung Cancer Care-Addressing Disparities, Challenges, and Pathways Forward

BACKGROUND

Lung cancer is the leading cause of cancer-related mortality in the United States, which disproportionately affect racial and ethnic minorities. Disparities in lung cancer screening, diagnosis, treatment, and survival outcomes are due to a complex interplay of socioeconomic factors, structural racism, and limited access to high-quality care. This review aims to examine the underlying causes of these disparities and explore potential mitigation strategies to improve lung cancer care equity.

METHODS

A review of the literature was conducted, evaluating racial and ethnic disparities in lung cancer care. Disparities in lung cancer screening, genomic testing, surgical and systemic treatment, and survival were explored. Additionally, interventional strategies such as risk-based screening, patient navigation programs, and policy reforms were examined.

RESULTS

Racial and ethnic minority patients are diagnosed at younger ages with fewer pack-years yet are less likely to qualify for screening under current guidelines. They receive lower rates of guideline-concordant treatment, including surgery, radiation, chemotherapy, and biomarker testing, and have reduced access to specialty care. Socioeconomic barriers, medical mistrust, and geographic disparities further contribute to these inequities. Targeted interventions, including mobile screening programs, financial assistance initiatives, and culturally competent care, have shown promise in improving lung cancer outcomes.

CONCLUSION

A multi-level approach, incorporating healthcare policy changes, improved screening criteria, and an enhanced community engagement strategy, is essential for achieving equitable lung cancer care, ultimately improving outcomes for racial minority populations.

Using Culturally Adapted Theater Outreach to Promote Cancer Screening Among Medically Underserved Minority Communities

Black, Hispanic, and Asian individuals, the three largest US racial/ethnic minorities, continue to suffer disproportionately from breast, cervical, and colon cancers largely because cancer screening continues to be underutilized even after decades of availability. This study examined the utility of theoretically grounded and culturally adapted in-person theater monologues aimed at promoting early detection screening among the three highest population racial/ethnic groups in Harris County, Houston, TX. Nine monologues were created to promote cancer screening and early detection for breast, cervical, and colorectal cancers in three different languages (English, Spanish, Vietnamese) and targeting underserved Black, Hispanic, and Vietnamese adult Harris County residents. From January 2014 to March 2020, 265 live monologue outreach events were held with 110 focused on prevention and screening for breast cancer, 75 for colorectal cancer, and 80 for cervical cancer. A total of 5989 individuals attended these outreach events and 86.3% completed the post-performance evaluation survey. Overall for all monologues, 6.6% of participants reported a positive change in their intent to screen from 75.7 to 82.3% after intervention (p < 0.001) and audience member scores on knowledge questions for all three cancers were mostly positive. Importantly, early detection questions for all three cancers were over 90% correct for all respondents, and well over 70% for the various groups. The findings revealed opportunities for improving monologue content to cultivate cancer early detection and screening knowledge. Results suggest that a theater-based approach may be an effective strategy to disseminate cancer screening education, improve knowledge, and increase intent to obtain screening among medically underserved communities.

Real-World Adherence to Multi-Target Stool DNA Testing for Colorectal Cancer Among Asian Americans

Introduction: Asian Americans have lower colorectal cancer (CRC) screening rates compared to other racial/ethnic groups. Given the importance of early detection and subsequent treatment in improving survival, this study examines adherence to first-time multitarget stool DNA (mt-sDNA) testing among Asian American patients.Methods: This retrospective study linked two data sources: Komodo Research Data + MapEnhance Komodo Lab database and the Exact Sciences Laboratories database. Asian American's 45 years and older who were first-time users of mt-sDNA testing between 2017 and 2023, with continuous insurance enrollment for two years, were included. Adherence to mt-sDNA testing was analyzed using descriptive statistics and logistic regression to identify factors associated with adherence.Results: The final sample included 336 288 Asian American patients, primarily covered by commercial insurance (70.3%), aged 50-75 years (80.7%), female (56.5%), living in metropolitan areas (95.4%), and under the care of a primary care physician (74.9%). Overall adherence to mt-sDNA testing was 70.9%, with significant variation by payer type ranging from 60.7% for Medicaid to 72.2% for Medicare (P < 0.0001). Overall adherence rates were approximately 70% across all age groups, sexes, and geographic regions but were notably high among gastroenterology (GI) provider patients (81.6%) and those receiving full digital outreach (via both SMS and email) (72.8%). Logistic regression identified several significant predictors of adherence: older age, males, coverage by commercial insurance, residing outside metropolitan areas, seeing GI providers, receiving digital outreach via SMS or both SMS and email, and preferring English.Conclusion: This study found that Asian American patients that were first-time users of mt-sDNA testing had high adherence rates. However, significant disparities existed within this population based on payer type and sociodemographic factors. Targeted outreach strategies are essential to reduce barriers and improve CRC screening uptake, ultimately reducing the burden of CRC in the Asian American population.

Cultural and Linguistic Adaptation of an Evidence-Based Tailored Navigation Intervention to Increase Cancer Screening Uptake Among Southeast Asian Women

BackgroundSoutheast Asian immigrant women in the U.S. have high rates of breast and cervical cancer, yet they are the least likely of all racial/ethnic groups to get screened. To address this disparity, we adapted the evidence-based Tailored Intervention Messaging System© (TIMS©), which uses tailored messages and navigation by culturally and linguistically matched community health advisors to overcome barriers to cancer screening.ObjectivesThis study describes the cultural and linguistic adaptation of TIMS© to improve breast and cervical cancer screening among Southeast Asian immigrant women in the U.S.MethodsGuided by Stirman et al.'s adaptation framework, we conducted focus groups and in-depth interviews to identify key constructs related to cancer screening (knowledge, perceived barriers, perceived risk, benefits, self-efficacy). Using the TIMS© and the thematic content from qualitative data, we modified messages for content and context. Messages were divided into three categories: 1) existing messages identified in thematic analyses, 2) existing messages not identified in thematic analyses, and 3) new messages that emerged from thematic analyses.ResultsContextual and content modifications were made to the TIMS© message library. Messages were translated into Lao, Khmer, and Vietnamese. Through an iterative process, the investigator, community health advisors, and cultural community advisory board members reviewed and revised the messages for translation accuracy, relevance, and clarity.ConclusionUsing relatable language and context is critical to engaging women from Southeast Asian communities in improving breast and cervical cancer screening uptake. This adaptation approach can be applied to tailor interventions for other languages, cultures, and underrepresented groups.

Cancer Screening, Knowledge, and Fatalism among Chinese, Korean, and South Asian Residents of New York City

BACKGROUND

Asian New York City residents have the lowest cancer screening uptake across race and ethnicity. Few studies have examined screening differences across Asian ethnic subgroups in New York City.

METHODS

Cross-sectional survey data were analyzed using multivariable logistic and multinomial regression analyses. Differences among Chinese, Korean, and South Asian adults in breast, cervical, and colorectal cancer screening uptake; breast and colorectal cancer screening knowledge; and cancer fatalism were examined. Associations between breast and colorectal cancer screening knowledge and their uptake were also assessed along with associations between cancer fatalism and breast, cervical, and colorectal cancer screening uptake.

RESULTS

Korean women reported 0.52 times [95% confidence interval (CI), 0.31-0.89] lower odds of Pap test uptake compared with Chinese women; South Asian adults had 0.43 times (95% CI, 0.24-0.79) lower odds of colorectal cancer screening uptake compared with Chinese adults. Korean adults reported 1.80 times (95% CI, 1.26-2.58) higher odds of knowing the correct age to begin having mammograms compared with Chinese adults; South Asian adults had 0.67 times (95% CI, 0.47-0.96) lower odds of knowing the correct age to begin colorectal cancer screening compared with Chinese adults. Korean adults had 0.37 times (95% CI, 0.27-0.53) lower odds of reporting cancer fatalism compared with Chinese adults.

CONCLUSIONS

Low cancer screening uptake among Asian American adults, low screening knowledge, and high cancer fatalism were found. Cancer screening uptake, knowledge, and fatalism varied by ethnic subgroup.

IMPACT

Findings indicate the need for ethnicity-specific cultural and linguistic tailoring for future cancer screening interventions.

Surgical Outcomes and Utilization of Laparoscopic Versus Robotic Techniques for Elective Colectomy in Asian American and Native Hawaiian-Pacific Islanders (AAPI) Diagnosed With Colon Cancer

INTRODUCTION

Asian American and Native Hawaiian-Pacific Islanders (AAPI) are the fastest growing racial-ethnic group, with 18.9 million people in 2019, and is predicted to rise to 46 million by 2060. Colorectal cancer (CRC) is the most common cancer in AAPI men and the third most common in women. Treatment techniques like laparoscopic colectomy (LC) emerged as the standard of care for CRC resections; however, new robotic technologies can be advantageous. Few studies have compared clinical outcomes across minimally invasive approaches for AAPI patients with CRC. This study compares utilization and clinical outcomes of LC versus robotic colectomies (RCs) in AAPI patients.

METHODS

We queried the American College of Surgeons National Surgical Quality Improvement Program database for elective RC and LC in AAPI patients from 2012 to 2020. Outcomes included unplanned conversion to open, operative time, complications, 30-d mortality, and length of stay. Multivariable logistic regression analyses assessed the association between outcomes and the operative approach.

RESULTS

Between 2012 and 2020, 83,841 patients underwent elective LC or RC. Four thousand six hundred fifty-eight AAPI patients underwent 3817 (82%) LCs and 841 (18%) RCs. In 2012, all procedures were performed laparoscopically; by 2020, 27% were robotic. Mean operative time was shorter in LC (192 versus 249 min, P < 0.001). On multivariable logistic regression, there was no difference in infection (odds ratio [OR] 0.8, 95% confidence interval [CI] 0.59-1.12), anastomotic leak (OR 0.97, 95% CI 0.59-1.61), or death (OR 0.9, 95% CI 0.31-2.61). Length of stay was shorter for RC (-0.44 d, 95% CI -0.71 to -0.18 d).

CONCLUSIONS

Overall, AAPI postoperative outcomes are similar between LC and RC. Future studies that evaluate costs and resource utilization can assist hospitals in determining whether implementing robotic-assisted technologies in their hospitals and communities will be appropriate.

Video Interventions for Reducing Health Inequity in Cancer Screening Programmes: a Systematic Review

BACKGROUND

Health equity can lead to disparities in cancer screening, treatment, and mortality. This systematic review aims to identify and describe interventions that used video or DVD formats to reduce health inequity in cancer screening and review the effectiveness of such interventions in increasing screening rates compared to usual care conditions.

METHODS

We searched PubMed, Web of Science, Embase, and Cochrane databases for randomized control trials (RCTs) published until 18/01/2023 that compared intervention versus usual care control groups, with the percentage of cancer screening uptake during follow-up as an outcome. The risk of Bias was assessed with the Cochrane Collaboration tool.

RESULTS

After screening 4201 abstracts, 192 full texts were assessed for eligibility and 18 were included that focused on colorectal (n = 9), cervical (n = 5), breast (n = 5), and prostate (n = 1) cancer screening. All were based in the USA except one and most focused on ethnicity/race, while some included low-income populations. Most of the video interventions used to increase cervical cancer screening reported positive results. Studies aimed at increasing mammography uptake were mostly effective only in specific groups of participants, such as low-income or less-educated African American women. Results for colorectal cancer screening were conflicting. Videos that were culturally tailored or used emotive format were generally more effective than information-only videos.

CONCLUSIONS

Video interventions to increase cancer screening among populations with low screening uptake show some positive effects, though results are mixed. Interventions that use individual and cultural tailoring of the educational material should be further developed and investigated outside of the USA.

Predictors of Colonoscopy Use Among Asian Indians in New York City, 2003 to 2016

BACKGROUND

Asian Americans have the lowest colorectal cancer screening uptake of any racial and ethnic group in the United States. Asian Indians are among the most under-screened Asian American subgroups, but there is limited data for this population. We sought to characterize predictors of colonoscopy use among Asian Indians in New York City.

METHODS

Using 2003 to 2016 data from the New York City Community Health Survey, we identified all Asian Indian participants aged 50 years or older. We examined the association between sociodemographic and medical factors and up-to-date colonoscopy use (defined as colonoscopy within the last 10 y) using logistic regression over 4 time periods: 2003 to 2008, 2009 to 2012, 2013 to 2014, 2015 to 2016.

RESULTS

On multivariable analysis, language, age, income, recent exercise, body mass index, and influenza vaccination were associated with colonoscopy uptake in 1 time period. Compared with participants who preferred English, those who preferred an Indian language were less likely to have been up-to-date in 2013 to 2014 (odds ratio 0.12, 95% CI 0.02-0.66). Individuals older than 65 years were more likely than those aged 50 to 64 years to have received a colonoscopy in 2009 to 2012 (odds ratio 3.91, 95% CI 1.49-10.24), although the risk estimates were also consistently positive in the other 3 time periods.

CONCLUSIONS

Among Asian Indians living in New York City, several demographic, socioeconomic, and health-related characteristics predict colonoscopy use. These findings highlight the importance of examining determinants of colonoscopy uptake in this understudied population to inform future public health interventions.

Association between the social vulnerability index and breast, cervical, and colorectal cancer screening rates in Rhode Island

BACKGROUND

Cancer screening is effective in reducing the burden of breast, cervical, and colorectal cancers, but not all communities have appropriate access to these services. In this study, we aimed to identify under-resourced communities by assessing the association between the Social Vulnerability Index (SVI) with screening rates for breast, cervical, and colorectal cancers in ZIP-code tabulation areas (ZCTAs) in Rhode Island.

METHODS

This study leveraged deidentified health insurance claims data from HealthFacts RI, the state's all-payer claims database, to calculate screening rates for breast, cervical, and colorectal cancers using Healthcare Effectiveness Data and Information Set measures. We used spatial autoregressive Tobit models to assess the association between the SVI, its four domains, and its 15 component variables with screening rates in 2019, accounting for spatial dependencies.

RESULTS

In 2019, 73.2, 65.0, and 66.1% of eligible individuals were screened for breast, cervical, and colorectal cancer, respectively. For every 1-unit increase in the SVI, screening rates for breast and colorectal cancer were lower by 0.07% (95% CI 0.01-0.08%) and 0.08% (95% CI 0.02-0.15%), respectively. With higher scores on the SVI's socioeconomic domain, screening rates for all three types of cancers were lower.

CONCLUSION

The SVI, especially its socioeconomic domain, is a useful tool for identifying areas that are under-served by current efforts to expand access to screening for breast, cervical, and colorectal cancer. These areas should be prioritized for new place-based partnerships that address barriers to screening at the individual and community level.

What factors influence the uptake of bowel, breast and cervical cancer screening? An overview of international research

BACKGROUND

For cancer screening programmes to be effective in early detection it is important that those invited can access screening services and understand the benefits of participation. A better understanding of the factors that matter to potential participants of cancer screening programmes can assist in developing strategies to increase current uptake.

METHODS

We conducted an overview of systematic reviews to answer the question: What factors influence the uptake of cancer screening services (breast, bowel and cervical) in high-income countries? A thematic approach supported by tabular summaries and qualitative heat maps was used to categorize factors, described as 'barriers' or 'facilitators'.

RESULTS

A total of 41 systematic reviews met the criteria for inclusion. The barrier with the greatest number of 'hot spots' across all three screening programmes was a fear of the unknown regarding a possible diagnosis of cancer or abnormal screening results, followed closely by a general lack of knowledge surrounding cancer screening programmes. The greatest collective facilitator to uptake was recommendation by a healthcare provider to attend screening.

CONCLUSION

Across all factors 'trust' and 'building trusted relationships' can be seen as integral to the success of cancer screening programmes and must be reflective of collaborative efforts to mitigate barriers and enhance facilitators to uptake. There is future scope to consider interventions that (i) increase demand for screening services, (ii) reduce barriers to uptake of services and/or (iii) are relevant to the healthcare system and those providing services.

Health Literacy among Korean American Immigrant Women in the USA: Role of Social Support

Health literacy is associated with health behaviors and outcomes. Using Andersen's Behavioral Model of Health Services Use, this study examined the role of limited English proficiency (LEP) and social support for the health literacy of Korean American immigrant women, one of the most affected groups by LEP. Researchers surveyed 232 Korean American immigrant women in a metro area in a Southeastern state, U.S. Health literacy was measured by the CDC Behavioral Risk Factor Surveillance System Questionnaire and the California Health Interview Survey. Participants with better English proficiency and larger social support had higher health literacy. LEP and social support interaction was significantly associated with health literacy, illustrating social support as a buffer that mitigates the negative impact of LEP on health literacy. Community programs that enhance social support through community health advocates or peer educators may increase health literacy and reduce health disparities among Korean American immigrant women with LEP.

Turning the Health Equity Lens to Diversity in Asian American Health Profiles

The monolithic misrepresentation of Asian American (AsAm) populations has maintained assumptions that AsAm people are not burdened by health disparities and social and economic inequities. However, the story is more nuanced. We critically review AsAm health research to present knowledge of AsAm health profiles from the past two decades and present findings and opportunities across three topical domains: (a) general descriptive knowledge, (b) factors affecting health care uptake, and (c) effective interventions. Much of the literature emphasized underutilization of health care services; low knowledge and awareness among AsAms about health-related risk factors, prevention, diagnosis, and treatment; inadequate efforts by health systems to improve language access, provider-patient communication, and trust; and the critical roles of community- and faith-based organizations and leaders in health promotion initiatives. Future opportunities for AsAm health research will require adoption of and significant investment in community-engaged research infrastructure to increase representation, funding, and research innovation for AsAm communities.

Exploring patterns of alcohol use and alcohol use disorder among Asian Americans with a finer lens

BACKGROUND

National survey data suggest Asian Americans (AA) are less likely to consume alcohol and develop AUD than Americans in other groups. However, it is common for AA to be born outside of the US and carry gene variants that alter alcohol metabolism, both of which can lead to lower levels of alcohol involvement. The current study examined differences in alcohol use and AUD between AA and other groups before and after controlling for birth location and gene variants.

DESIGN

Past year alcohol measures were examined from adults 18+ (N=22,848) in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions III before and after controlling for birth location (inside or outside of the US) and gene variants (ALDH2*2 and ADH1B*2/ADH1B*3). Gender gaps in alcohol measures also were assessed.

RESULTS

Before adjustments, AA were less likely than White Americans to drink in the previous year (OR=0.50, 95% CI 0.41-0.62), binge (OR=0.68, 95% CI 0.52-0.88), engage in frequent heavy drinking (OR=0.55, 95% CI 0.42-0.73), and reach criteria for AUD (OR=0.71, 95% CI 0.53-0.94). After controlling for birth location and gene variants, AA remained less likely to drink in the past year (OR=0.54, 95% CI 0.41-0.70) but all other differences disappeared. Gender gaps were only observed for AA born outside of the US, highlighting the importance of experience rather than racial category per se.

CONCLUSIONS

Findings indicate that heterogeneity among AA leads to spurious generalizations regarding alcohol use and AUD and challenge the model minority myth.

Unique Breast Cancer Screening Disparities in a Safety-Net Health System

INTRODUCTION

Breast cancer screening (BCS) disparities leave historically underserved groups more vulnerable to adverse outcomes. This study explores granular associations between BCS and patient sociodemographic factors in a large urban safety-net health system.

METHODS

A retrospective review among female patients ages 50-74 within an urban safety-net health system was conducted in 2019. All patients had a primary care visit in the past 2 years. Multiple patient health and sociodemographic characteristics were reviewed, as well as provider gender and specialty. Bivariate analyses and multivariable logistic regression were performed in 2022.

RESULTS

The BCS rate among 11,962 women was 69.7%. Over half of patients were non-White (63.6%) and had public insurance (72.3%). Patients with limited English proficiency made up 44.3% of the cohort. Compared to their sociodemographic counterparts, patients with White race, English proficiency, and Medicare insurance had the lowest rates of BCS. Serious mental illness and substance use disorder were associated with lower odds of BCS. In multivariable analysis, when using White race and English speakers as a reference, most other races (Black, Hispanic, and Other) and languages (Spanish, Portuguese, and Other) had significantly higher odds of screening ranging from 8% to 63% higher, except Asian race and Haitian Creole language. Female (versus male) and internal medicine-trained providers were associated with higher screening odds.

CONCLUSIONS

Multiple unique variables contribute to BCS disparities, influenced by patient and health system factors. Defining and understanding the interplay of these variables can guide policymaking and identify avenues to improve BCS for vulnerable or traditionally under-resourced populations.

Examining cancer screening disparities by race/ethnicity and insurance groups: A comparison of 2008 and 2018 National Health Interview Survey (NHIS) data in the United States

BACKGROUND

Pervasive differences in cancer screening among race/ethnicity and insurance groups presents a challenge to achieving equitable healthcare access and health outcomes. However, the change in the magnitude of cancer screening disparities over time has not been thoroughly examined using recent public health survey data.

METHODS

A retrospective cross-sectional analysis of the 2008 and 2018 National Health Interview Survey (NHIS) database focused on breast, cervical, and colorectal cancer screening rates among race/ethnicity and insurance groups. Multivariable logistic regression models were used to assess the relationship between cancer screening rates, race/ethnicity, and insurance coverage, and to quantify the changes in disparities in 2008 and 2018, adjusting for potential confounders.

RESULTS

Colorectal cancer screening rates increased for all groups, but cervical and mammogram rates remained stagnant for specific groups. Non-Hispanic Asians continued to report consistently lower odds of receiving cervical tests (OR: 0.42, 95% CI: 0.32-0.55, p<0.001) and colorectal cancer screening (OR: 0.55, 95% CI: 0.42-0.72, p<0.001) compared to non-Hispanic Whites in 2018, despite significant improvements since 2008. Non-Hispanic Blacks continued to report higher odds of recent cervical cancer screening (OR: 1.98, 95% CI: 1.47-2.68, p<0.001) and mammograms (OR: 1.32, 95% CI: 1.02-1.71, p<0.05) than non-Hispanic Whites in 2018, consistent with higher odds observed in 2008. Hispanic individuals reported improved colorectal cancer screening over time, with no significant difference compared to non-Hispanics Whites in 2018, despite reporting lower odds in 2008. The uninsured status was associated with significantly lower odds of cancer screening than private insurance for all three cancers in 2008 and 2018.

CONCLUSION

Despite an overall increase in breast and colorectal cancer screening rates between 2008 and 2018, persistent racial/ethnic and insurance disparities exist among race/ethnicity and insurance groups. These findings highlight the importance of addressing underlying factors contributing to disparities among underserved populations and developing corresponding interventions.

Interactive or tailored digital interventions to increase uptake in cervical, breast, and colorectal cancer screening to reduce health inequity: a systematic review

BACKGROUND AND OBJECTIVES

Significant health inequities exist in screening uptake for certain types of cancer. The review question was to identify and describe interactive, tailored digital, computer, and web-based interventions to reduce health inequity in cancer screening and review the effectiveness of such interventions in increasing screening rates versus usual care.

METHODS

We searched four medical literature databases for randomized control trials (RCTs) published until 12 January 2023 that evaluated interventions aimed at increasing the percentage of breast, prostate, cervical, or colorectal cancer screening uptake. Meta-analysis was not conducted due to heterogeneity among studies.

RESULTS

After screening 4200 titles and abstracts, 17 studies were included. Studies focused on colorectal ( n  = 10), breast ( n  = 4), cervical ( n  = 2), and prostate ( n  = 1) cancer screening. All were based in the USA except two. Most studies focused on ethnicity/race, while some included low-income populations. Intervention types were heterogeneous and used computer programs, apps, or web-based methods to provide tailored or interactive information to participants about screening risks and options. Some studies found positive effects for increasing cancer screening uptake in the intervention groups compared to usual care, but results were heterogeneous.

CONCLUSION

Interventions that use individual and cultural tailoring of cancer screening educational material should be further developed and investigated outside of the USA. Designing effective digital intervention strategies, with components that can be adapted to remote delivery may be an important strategy for reducing health inequities in cancer screening during the coronavirus disease 2019 pandemic.

The effectiveness of patient navigation services in reducing cancer screening disparities among Asian Americans

OBJECTIVES

Patient navigation has served as a useful intervention to reduce cancer disparities among diverse ethnic groups. Previous studies have consistently shown the effectiveness of patient navigation in reducing cancer disparities for ethnic minorities; however, few studies have been conducted for cancer screening behaviors focusing on the Asian population. This study aims to identify the overall effectiveness of patient navigation in cancer screening behaviors among Asian Americans through meta-analyses. In addition, this study examines the moderating effects of the type of cancers on cancer screening behaviors.

DESIGN

For data analyses, we selected 15 studies through a systematic review and meta-analyses, searching the databases of PubMed, Web of Science, Embase, Scopus, and Cochrane Library. Random-effects models were used for meta-analyses.

RESULTS

The results showed that Asian Americans who received patient navigation were more likely to participate in cancer screening behaviors than those who did not receive patient navigation regardless of the type of cancer. Publication bias was tested using a funnel plot, meta-regression, and Failsafe-N. No notable publication bias was found.

CONCLUSION

This study can provide comprehensive evidence regarding the overall effectiveness of patient navigation in cancer screening behaviors of Asian Americans.

Disparate Utilization of Breast Conservation Therapy in the Surgical Management of Early-Stage Breast Cancer

BACKGROUND

Despite evidence suggesting oncologic equipoise of breast conservation therapy (BCT) for early-stage (stages I and II) breast cancer, mastectomy is still widely utilized.

PATIENTS AND METHODS

The 2004-2015 National Cancer Database was used to tabulate all adult women receiving mastectomy or BCT for early-stage breast cancer. Multivariable regression was used to evaluate factors associated with utilization of BCT, relative to mastectomy.

RESULTS

Of 1,079,057 women meeting study criteria, 57.4% underwent BCT. BCT patients were older and more commonly White, compared to mastectomy. They were more commonly privately insured, in the highest income quartile, and treated at metropolitan, nonacademic institutions. After adjustment, increasing age (AOR 1.01/year), Black race (AOR 1.21, Ref: White), and care at a community hospital (AOR 1.08, Ref: Academic; all P< .05) were associated with increased odds of undergoing BCT. Conversely, Asian or Pacific Islander (AAPI) race (AOR 0.74), Medicare (AOR 0.89) or Medicaid (AOR 0.95) coverage, and being in the lowest (AOR 0.95) and second lowest (AOR 0.98, all P< .05) income quartiles were associated with reduced odds of undergoing BCT. Finally, increasing tumor size (AOR 0.97, P< .05) was associated with decreased adjusted odds of undergoing BCT.

CONCLUSION

Our results suggest persistent socioeconomic and racial disparities in BCT utilization for early-stage breast cancer. Directed strategies should be implemented in order to reduce treatment inequality in this patient population.

Exploring the complexity and spectrum of racial/ethnic disparities in colon cancer management

BACKGROUND

Colorectal cancer is a leading cause of morbidity and mortality across U.S. racial/ethnic groups. Existing studies often focus on a particular race/ethnicity or single domain within the care continuum. Granular exploration of disparities among different racial/ethnic groups across the entire colon cancer care continuum is needed. We aimed to characterize differences in colon cancer outcomes by race/ethnicity across each stage of the care continuum.

METHODS

We used the 2010-2017 National Cancer Database to examine differences in outcomes by race/ethnicity across six domains: clinical stage at presentation; timing of surgery; access to minimally invasive surgery; post-operative outcomes; utilization of chemotherapy; and cumulative incidence of death. Analysis was via multivariable logistic or median regression, with select demographics, hospital factors, and treatment details as covariates.

RESULTS

326,003 patients (49.6% female, 24.0% non-White, including 12.7% Black, 6.1% Hispanic/Spanish, 1.3% East Asian, 0.9% Southeast Asian, 0.4% South Asian, 0.3% AIAE, and 0.2% NHOPI) met inclusion criteria. Relative to non-Hispanic White patients: Southeast Asian (OR 1.39, p < 0.01), Hispanic/Spanish (OR 1.11 p < 0.01), and Black (OR 1.09, p < 0.01) patients had increased odds of presenting with advanced clinical stage. Southeast Asian (OR 1.37, p < 0.01), East Asian (OR 1.27, p = 0.05), Hispanic/Spanish (OR 1.05 p = 0.02), and Black (OR 1.05, p < 0.01) patients had increased odds of advanced pathologic stage. Black patients had increased odds of experiencing a surgical delay (OR 1.33, p < 0.01); receiving non-robotic surgery (OR 1.12, p < 0.01); having post-surgical complications (OR 1.29, p < 0.01); initiating chemotherapy more than 90 days post-surgery (OR 1.24, p < 0.01); and omitting chemotherapy altogether (OR 1.12, p = 0.05). Black patients had significantly higher cumulative incidence of death at every pathologic stage relative to non-Hispanic White patients when adjusting for non-modifiable patient factors (p < 0.05, all stages), but these differences were no longer statistically significant when also adjusting for modifiable factors such as insurance status and income.

CONCLUSIONS

Non-White patients disproportionately experience advanced stage at presentation. Disparities for Black patients are seen across the entire colon cancer care continuum. Targeted interventions may be appropriate for some groups; however, major system-level transformation is needed to address disparities experienced by Black patients.

Interventions to reduce cancer screening inequities: the perspective and role of patients, advocacy groups, and empowerment organizations

BACKGROUND

Health inequities lead to low rates of cancer screening in certain populations, such as low-income and ethnic minority groups. Different interventions to address this have been developed with mixed results. However, interventions are not always developed in collaboration with the people they target. The aim of our article is to present the viewpoint of patients, survivors, advocates, and lay persons on interventions to increase cancer screening from a health inequity perspective.

METHODS

We prepared talking points to guide discussions between coauthors, who included representatives from nine patient and survivor advocacy groups, organizations working for citizen/patient empowerment, and health equity experts. Perspectives and opinions were first collected through video conferencing meetings and a first draft of the paper was prepared. All authors, read through, revised, and discussed the contents to reach an agreement on the final perspectives to be presented.

RESULTS

Several themes were identified: it is important to not view screening as a discrete event; barriers underlying an individual's access and willingness to undergo screening span across a continuum; individually tailored interventions are likely to be more effective than a one-size fits-all approach because they may better accommodate the person's personal beliefs, knowledge, behaviors, and preferences; targeting people who are unknown to medical services and largely unreachable is a major challenge; including professional patient advocacy groups and relevant lay persons in the cocreation of interventions at all stages of design, implementation, and evaluation is essential along with relevant stakeholders (healthcare professionals, researchers, local government and community organizations etc).

CONCLUSIONS

Interventions to address cancer screening inequity currently do not adequately solve the issue, especially from the viewpoint of patients, survivors, and lay persons. Several core pathways should be focused on when designing and implementing interventions: advancing individually tailored interventions; digital tools and social media; peer-based approaches; empowerment; addressing policy and system barriers; better design of interventions; and collaboration, including the involvement of patients and patient advocacy organizations.

Cancer beliefs and screening behaviors: The impact of neighborhood and other social determinants of health

Background

Beliefs about cancer influence breast and colorectal cancer (CRC) screening behavior. Screening rates for these cancers differ in the contiguous neighborhoods of East Harlem (EH), Central Harlem (CH), and the Upper East Side (UES), which have distinct socio-demographic compositions. We assessed the belief-screening behavior relationship in these neighborhoods.

Methods

The 2019 Community Cancer Needs Survey included adults eligible for breast and/or colorectal cancer screening. Raking was used to generate neighborhood-specific distribution estimates. Categorical variables were compared using Chi-square tests. Stepwise logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI) for the association between cancer beliefs and screening.

Results

Our weighted sample included 147,726 respondents. Screening was 75% in CH, 81% in EH, and 90% in the UES for breast cancer, and 71%, 76%, and 92% for CRC, respectively. The fatalistic belief "There's not much you can do to lower your chances of getting cancer" differed by neighborhood with screening more likely in CH respondents (breast OR =1.45 and colorectal OR =1.11), but less likely in EH (OR= 0.77 and 0.37, respectively). UES ORs were not generated due to too few unscreened respondents.

Conclusions

Cancer beliefs were inconsistently associated with breast and CRC screening across three NYC neighborhoods. This suggests that a given belief may either motivate or deter screening, depending upon context or interpretation. Once access is addressed, efforts seeking to enhance screening rates should consider implications of communities' varying beliefs.

Understanding responses to different types of conflicting information about cancer prevention

BACKGROUND

Individuals are regularly exposed to conflicting information about health; however, understanding of how individuals respond to different types of conflicting information is limited.

METHODS

In total, 1027 US adults were randomly assigned to 1 of 8 conflicting information messages about nutrition and cancer risk, depicting 1/4 conflicting information types (conflict in evidence - sources A and B agree the evidence is mixed; conflict between two expert sources - sources A and B present conflicting evidence about nutrition and cancer risk; conflict within the same expert source - source A changes its own recommendation about the evidence; no conflict control) crossed by 1/2 baseline recommendations with which new information conflicted (limit vs. do not limit red meat intake to reduce cancer risk).

RESULTS

Compared to the control, each conflicting information type led to lower perceived scientific consensus about how much red meat one should eat (p < .001); conflict in evidence (p = .004) and between sources (p = .006) led to lower trust in scientists. Intentions to consume red meat more frequently were higher in the conflicting information conditions than control in the group initially told to "limit red meat" and lower in the "do not limit red meat" group (p = .022). Conflict within the same source led to higher perceived scientific consensus compared to conflict in evidence (p = .007) and between sources (p = .013); it also lowered intentions to consume red meat more frequently compared to conflict in evidence, but only in the "do not limit red meat" condition (p = .033). Conflict in evidence (p = .007) and within the same source (p = .013) increased cancer fatalism compared to conflict between sources.

CONCLUSIONS

Conflict in scientific evidence and conflict arising from the same expert source (e.g., a changing public health guideline) may have pernicious effects. Future efforts could investigate how best to publicly communicate these instances of scientific conflict to minimize negative impact.

Pathologic characteristics, patterns of care, and outcomes of Asian-Americans and Pacific islanders with uterine cancer

OBJECTIVES

To compare the patterns of care and outcomes of Asian-Americans/Pacific Islanders (AAPI) to non-Hispanic White (NHW) women with uterine cancer, and examine differences across Asian country of origin.

METHODS

National Cancer Database was used to identify AAPI and NHW women with uterine cancer diagnosed from 2004 to 2017. Marginal multivariable log-linear regression models and Cox proportional-hazards models were developed to estimate differences in quality-of-care and all-cause mortality between AAPI and NHW women and across AAPI ethnic groups.

RESULTS

We identified 13,454 AAPI and 354,693 NHW women. Compared to NHW women, AAPI patients were younger at diagnosis (median age 57 vs. 62 years), had fewer comorbidities, more often had serous or sarcoma histologic subtypes and stage III/IV cancer. AAPI women had a slightly higher rate of receiving pelvic lymphadenectomy for deeply invasive or high-grade tumors (77.6% vs. 74.3%), and a lower rate of undergoing minimally invasive surgery (70.4% vs. 74.8%) for stage I-IIIC tumors. Among patients undergoing hysterectomy, AAPI women had a lower mortality compared with NHW women for cancer stage I/II/III, and a 28% reduction for type I (grade 1 or 2 endometrioid cancers) disease (aHR = 0.72; 95% CI, 0.64-0.81). Among AAPI subgroups, Pacific Islanders had the worst survival across different cancer stage and disease type.

CONCLUSION

AAPI women are diagnosed with uterine cancer at a younger age and have more aggressive histologic subtypes and advanced stage than their White counterparts. They have a similar level of quality-of-care as NHW women, and an improved survival for early stage and type I disease.

Examining multilevel neighborhood socioeconomic characteristics associated with colorectal cancer screening in Vietnamese Americans residing in Philadelphia County

Colorectal cancer (CRC) is one of the most predominant cancers in the USA and ranks third among all cancers in incidence and mortality. Vietnamese Americans exhibit persistently lower screening rates compared to the general U.S. population, due to cultural, economic, and environmental barriers. The impact of environmental factors in particular is not well known, and lack of geographical access may be a significant barrier to accessing screening. This study aims to elucidate build and neighborhood environmental factors affecting CRC screening rates among Vietnamese Americans. A total of 517 Vietnamese Americans 50 years and older residing in Philadelphia County were included in the study. Surveys were collected to determine CRC screening behavior and sociodemographic characteristics. Individual neighborhood characteristics, which included the Walk Score, was obtained based on the participant's address. Neighborhood characteristics were calculated using census-tract level data for the social deprivation index, ethnic composition, and presence of hospitals or federally qualified health centers (FQHC). The generalized linear mixed model revealed that residing in an ethnically dense neighborhood was negatively associated with CRC screening (β = -0.67, SE = 0.29, p = .01), while social deprivation (β = 0.30, SE = 0.27, p = .27) and presence of FQHCs or hospitals (β = 0.16, SE = 0.30, p = .58) were not. Individual neighborhood characteristics including the Walk Score (β = 0.21, SE = 0.26, p = .43) was not associated with CRC screening behavior. Neighborhood characteristics, specifically ethnic density is associated with lower uptake of screening in this population. Future interventions should aim to target specific Vietnamese American and other Asian ethnic neighborhoods that may experience disparities in screening.

What are the effects of colorectal cancer screening interventions among Asian Americans? A meta-analysis

Objective: Great strides have been made to conduct intervention studies aimed at increasing colorectal cancer (CRC) screening rates that are informed by sound theoretical frameworks and conducted using rigorous methodologies; however, efforts are still gaining wave to understand the efficacy of theory-based interventions among Asian American (AA) population. The purpose of this study was to report the results of a meta-analysis conducted on the effects of CRC screening interventions.Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to evaluate the CRC screening interventions. Literature search was performed on October 2018, and studies published in English and conducted in the United States were eligible for inclusion if they (1) conducted interventions with aims to increase CRC screening rates among AA and (2) utilized a randomized control trial or quasi-experimental study design, (3) reported quantitative screening rates following the intervention, and (4) included a comparison or control group for comparison. No publication year restriction was applied.Result: In total, 14 Odds Ratio (OR) from 16 studies were included in the meta-analysis. Overall, results indicated that AA participants who received the screening interventions aimed at improving screening were 1.78 times more likely to obtain a CRC screening at post-intervention compared to those in the control or comparison group, OR = 1.78 (1.44, 2.11).Conclusion: Understanding the efficacy of interventions designed to promote CRC screening among AA population is imperative to decrease CRC burden and mortality. Although research in this area is limited, this review sheds light on important socio-cultural strategies to developing a CRC screening intervention aimed at increasing screening rates among AA. Findings in this review demonstrate that improvement in screening can be achieved through a variety of ways, but the common feature across all the studies was the culturally responsive foundation of their respective interventions.

Asian Ethnic Subgroup Disparities in Delays of Surgical Treatment for Breast Cancer

Background

As Asian American breast cancer incidence rises, it is necessary to investigate the origins of differential breast cancer outcomes among Asian ethnic subgroups. This study aimed to examine disparities in delays of breast cancer surgery among Asian ethnic subgroups.

Methods

We obtained California Cancer Registry data on female breast cancer diagnoses and treatment from 2012 to 2017. Our main independent variable was patient race and ethnicity, including 6 Asian ethnic subgroups. Dependent variables included time to surgical treatment for breast cancer and receipt of surgical treatment within 30 and 90 days of diagnosis. We conducted multivariable logistic regression to determine the odds of receiving surgery within 30 and 90 days of diagnosis and multivariable Cox proportional hazards regression to determine the risk of prolonged time to surgery.

Results

In our cohort of 93 168 breast cancer patients, Hispanic (odds ratio [OR] = 0.86, 95% confidence interval [CI] = 0.82 to 0.89) and non-Hispanic Black (OR = 0.83, 95% CI = 0.78 to 0.88) patients were statistically significantly less likely than non-Hispanic White patients to receive surgery within 30 days of breast cancer diagnosis, whereas Asian Indian or Pakistani (OR = 1.23, 95% CI = 1.09 to 1.40) and Chinese (OR = 1.30, 95% CI = 1.20 to 1.40) patients were statistically significantly more likely to receive surgery within 30 days of diagnosis.

Conclusions

This large, population-based retrospective cohort study of female breast cancer patients is the first, to our knowledge, to demonstrate that time to surgical treatment is not equal for all Asians. Distinct differences among Asian ethnic subgroups suggest the necessity of further investigating breast cancer treatment patterns to fully understand and target disparities in breast cancer treatment.

The Role of Education in Breast Cancer Beliefs and Screening Practices Among Korean Women - A quantitative study

INTRODUCTION

Cultural beliefs are influential factors that affect breast cancer screening practices among Korean women. The aim of this study was to examine the role of educational levels and compare the cultural beliefs associated with breast cancer screening practices among immigrant Korean women in Australia with those of their counterparts in Korea.

METHODS

A secondary analysis based on data from convenience samples of 245 and 249 Korean women living in Australia and Korea, respectively. Data were collected by the Korean version of Breast Cancer Screening Beliefs Questionnaire.

RESULTS

Educational level has a significant association with Korean women's cultural beliefs about breast cancer and breast cancer screening practices regardless of country of residence.

DISCUSSION

Nurses working in multicultural societies should take cultural beliefs and the role of education into account while designing strategies to promote breast cancer screening practices among immigrant Korean women.

Mammography Screening Disparities in Asian American Women: Findings From the California Health Interview Survey 2015-2016

PURPOSE

To identify mammography screening prevalence and predictors in Asian American women, focusing on the potential disparities in race and its influence on screening behaviors.

DESIGN

A secondary analysis utilized the California Health Interview Survey (CHIS) 2015-2016.

SETTING

California, U.S.

SAMPLE

Cisgender women who were non-Hispanic (NH) White, Chinese, Filipino, Vietnamese, Japanese, Korean, or "other Asian", aged 40 or above (unweighted N=13 451).

MEASURES

Socioeconomics, chronic health conditions, and preventive care utilization were mesuared as potential risk factors, where up-to-date mammography screening as the outcome variable.

ANALYSIS

Multivariable adjusted logistic regressions were generalized to identify the up-to-date mammography screening behaviors in relation to potential factors, stratified by race and ethnicity.

RESULTS

The prevalence for up-to-date mammography screening in NH-White and Asian American women were 68.06% and 65.97%, respectively. In NH-White women, receiving an up-to-date mammogram was associated with age, birthplace, smoking status, diabetes, hypertension, health insurance coverage, and a preventive care visit in the past 12 months, whereas only age and a preventive care visit were significant predictors in Asian women.

CONCLUSIONS

The findings indicate that utilization disparities exist in mammogram in relation to socioeconomics, chronic health conditions, preventive care utilization, when comparing between race and ethnicity. Asian American women with borderline hypertension and no preventive care visits may require more public health outreach and cancer education.

Effects of Neighborhood Ethnic Density and Psychosocial Factors on Colorectal Cancer Screening Behavior Among Asian American Adults, Greater Philadelphia and New Jersey, United States, 2014-2019

INTRODUCTION

We examined how neighborhood ethnic composition influences colorectal cancer (CRC) screening behavior in Asian American adults and explored whether associations between psychosocial predictors, including knowledge, self-efficacy, and barriers affecting CRC screening behavior, varied by level of neighborhood ethnic composition.

METHODS

Filipino, Korean, and Vietnamese Americans (N = 1,158) aged 50 years or older were included in the study. Psychosocial factors associated with CRC screening, CRC screening behavior, and sociodemographic characteristics were extracted from participants' data. Neighborhood ethnic composition was characterized as the census-tract-level percentage of Asian residents. Participants' addresses were geocoded to the census tract level to determine whether they resided in an ethnically dense neighborhood. Multilevel logistic regression models were run with and without interaction terms.

RESULTS

In mixed-effects logistic regression model 1, residing in an ethnically dense neighborhood was associated with lower odds of CRC screening (odds ratio [OR] = 0.65; 95% CI, 0.45-0.93; P = .02) after controlling for age, sex, education, ethnic group, and neighborhood socioeconomic status. Greater perceived barriers to CRC screening (OR = 0.62; 95% CI, 0.50-0.77; P < .001) resulted in significantly lower odds of obtaining a CRC screening, while higher self-efficacy (OR = 1.17, 95% CI, 1.11-1.23, P < .001) was associated with higher odds. In model 2, among those residing in a high ethnic density neighborhood, greater barriers to screening were associated with lower odds of having obtained a CRC screening (OR = 0.53; 95% CI, 0.30-0.96; P = .04).

CONCLUSION

We found that residing in an ethnically dense neighborhood indicated higher disparities in obtaining CRC screenings. Future studies should examine socioeconomic and cultural disparities, as well as disparities in the built environment, that are characteristic of ethnically dense neighborhoods and assess the impact of these disparities on CRC screening behaviors.

Racial and Ethnic Disparities in Lung Cancer Screening Eligibility

Background To address disparities in lung cancer screening (LCS) that may exclude large numbers of high-risk African American smokers, revised U.S. Preventive Services Task Force (USPSTF) recommendations lowered LCS eligibility thresholds. However, there are limited recent data about the impact of newly revised guidelines on disparities in LCS eligibility. Purpose To evaluate the impact of revised USPSTF guidelines on racial and ethnic disparities in LCS eligibility. Materials and Methods Cross-sectional survey data from 20 states were retrospectively evaluated from the 2019 Behavioral Risk Factor Surveillance System survey (median response rate, 49.4%). Respondents without a history of lung cancer aged 55-79 years (ie, under the previous guidelines) or aged 50-79 years (ie, under the revised guidelines) were included. Multivariable logistic regression analyses were performed to evaluate the association between race and ethnicity and LCS eligibility. All analyses were performed accounting for complex survey design features (ie, weighting, stratification, and clustering). Results Under previous guidelines, 11% of 67 567 weighted survey respondents were eligible for LCS (White [12%], Hispanic [4%], African American [7%], American Indian [17%], Asian or Pacific Islander [4%], and other [12%]). Under revised USPSTF guidelines, 14% of 77 689 weighted survey respondents were eligible for LCS (White [15%], Hispanic [5%], African American [9%], American Indian [21%), Asian or Pacific Islander [5%], and other [18%]). Compared with White respondents, African American respondents (adjusted odds ratio [OR] = 0.36; 95% CI: 0.27, 0.47; P < .001) and Hispanic respondents (adjusted OR = 0.15; 95% CI: 0.09, 0.24; P < .001) were less likely to be eligible for LCS under previous guidelines. African American respondents (adjusted OR = 0.39; 95% CI: 0.32, 0.47; P < .001) and Hispanic respondents (adjusted OR = 0.15; 95% CI: 0.10, 0.23; P < .001) were less likely to be eligible under the revised guidelines. The Wald test showed no evidence of differences in the degree to which racial and ethnic minority groups were less likely to be eligible for LCS when comparing previous versus revised USPSTF guidelines (P = .76). Conclusion The revised U.S. Preventive Services Task Force guidelines (version 2.0) may perpetuate lung cancer disparities, as racial and ethnic minority groups are still less likely to be eligible for lung cancer screening. © RSNA, 2021 Online supplemental material is available for this article.

Current Gaps in Breast Cancer Screening Among Asian and Asian American Women in the United States

Over the past two decades, the US Asian population has increased 72%, representing the fastest growth rate of any major racial group. Currently, there are over 20 million Asian and Asian American women in the United States, who identify with at least 1 of 19 different origin groups. Although women of Asian ancestry have traditionally been considered low risk for experiencing adverse breast cancer-specific outcomes, aggregated data may mask health disparities seen among subgroups. In the United States, recent data demonstrate that the burden of breast cancer among Asian women has increased each year over the past decade. We aim to characterize challenges faced by Asian and Asian American women in the United States related to cultural stigma, socioeconomic status, and overall access to breast cancer care. An increased understanding of barriers to breast cancer prevention and treatment efforts is needed to develop more effective strategies aimed at reducing disparities in care among segments of this heterogenous population.

Few changes shown in cancer information-seeking behaviour among young adults in China between 2012 and 2017

BACKGROUND

The increasing incidence of cancer among young adults (18-40 years old) is of concern in China.

OBJECTIVES

This study aims to examine the influence of cancer information-seeking behaviours (CISB) on young adults' worries about cancer and participation in screening.

METHODS

This study analysed data from two probability sample surveys conducted in 2012 and 2017 in China. The questions in the questionnaire remained the same for better comparison. The sample size was 1212 in the 2012 survey, and 2178 in the 2017 survey.

RESULTS

From 2012 to 2017, among young adults, there was a decline in cancer information seeking, diversity of cancer information sought and cancer worry, while an improvement in cancer information-seeking experience was found. Also, CISB had significant associations with cancer worry and health screening over the 5 years.

DISCUSSION

The level of young adults' cancer information seeking remains low in China, and this group is not fully aware of their potential risks of getting cancer.

CONCLUSION

Although young adults find the experience of looking for cancer information easier in 2017, health campaigns may be necessary to encourage young adults to find out more about their cancer risks, and to participate more in health screening.

Negative emotions and cancer fatalism are independently associated with uptake of Faecal Immunochemical Test-based colorectal cancer screening: Results from a population-based study

Although systematic colorectal cancer screening is efficacious, many programmes suffer from low uptake. Few behavioural or attitudinal factors have been identified as being associated with participation in colorectal cancer screening. We explored knowledge, beliefs about cancer, subjective health literacy, emotional attitudes to screening, and social influences among individuals invited to a population-based screening programme. Regression modelling of a cross-sectional survey of 2299 individuals (users and non-users) of a population-based Faecal Immunochemical Test (FIT) screening programme in Dublin was conducted. Questions were derived from previous theoretically-informed qualitative work and assessed using previously used and validated measures. The primary outcome variable was uptake status (User/Participation or Non-User/Non-participation); multivariable logistic regression was used to estimate the odds ratios (OR) for screening participation. Stronger fatalistic beliefs independently predicted lower uptake (OR = 0.94; 95% CI 0.90-0.98; P = 0.003). Those aged <65 who disagreed that "cancer can often be cured" also had lower uptake (OR = 0.43; 95% CI 0.22-0.82: P = 0.017). Agreement that the test was disgusting and tempting fate predicted lower uptake (OR = 0.16: 95% CI 0.10-0.27: p < 0.001), while the influence of a partner on decision to be screened was associated with higher uptake (OR = 1.32; 95% CI 1.15-1.50: P < 0.001). Negative cancer-related and screening-related beliefs and emotions are associated with non-participation in FIT (-based screening). Research is warranted to explore if these negative beliefs and emotions are modifiable and, if so, whether this would improve screening uptake. The association between the influence of a partner and screening participation present a challenge around improving uptake among those not in co-habiting relationships.

Associations between Fatalistic Cancer Beliefs and Cancer-Screening Behaviors in Chinese American Immigrant Women

Chinese Americans have among the lowest rates of up-to-date cancer screening in the United States. Fatalistic health beliefs are also common in this population and can lead to decreased healthcare utilization. We sought to understand how these fatalistic beliefs are associated with cancer screening behaviors in this underserved population. A cross-sectional survey was conducted with 732 Chinese women from the greater Chinatown area of Chicago, Illinois. Surveyed questions included sociodemographic information, self-reported healthcare utilization and cancer screening behaviors. The majority of respondents were older than 50, spoke Chinese, had less than a college education, public or no medical insurance, and an annual income  < $20,000. Approximately 20% had never received Papanicolaou or mammogram screening. Fatalistic beliefs were common and associated with increased health-seeking behaviors and appropriate Pap and mammogram screening. In this cohort of Chinese American immigrant women in an urban Chinatown community, fatalistic cancer beliefs were prevalent and associated with increased health-seeking and positive cancer screening behaviors. This previously unreported relationship could be leveraged in improving health outcomes of an underserved population.

Trends and Predictors for the Uptake of Colon Cancer Screening Using the Fecal Occult Blood Test in Spain from 2011 to 2017

Background: In Spain, colorectal cancer screening using the fecal occult blood test, targeted towards the 50–69 age bracket, was implemented on different dates. We aim to assess the temporal trend of colorectal cancer (CRC) screening uptake according to the year of screening implementation in each region and to identify predictors for the uptake of CRC screening. Methods: A cross-sectional study with 12,657 participants from the Spanish National Health Surveys 2011 and 2017 was used. Uptake rates were analyzed according to the date that the screening program was implemented. Results: For regions with programs implemented before 2011, the uptake rate increased 3.34-fold from 2011 to 2017 (9.8% vs. 32.7%; p < 0.001). For regions that implemented screening within the 2011–2016 period, the uptake rose from 4.3% to 13.2% (3.07-fold; p < 0.001), and for regions that implemented screening after 2016, the uptake increased from 3.4% to 8.8% (2.59-fold; p < 0.001). For the entire Spanish population, the uptake increased 3.21-fold (6.8% vs. 21.8%; p < 0.001). Positive predictors for uptake were older age, Spanish nationality, middle-to-high educational level, suffering chronic diseases, non-smoking and living in regions where screening programs were implemented earlier. Conclusions: The different periods for the implementation of CRC screening as well as sociodemographic and health inequalities may have limited the improvement in the screening uptake from 2011 to 2017 in Spain.

The Importance of Health Insurance in Addressing Asian American Disparities in Utilization of Clinical Preventive Services: 12-Year Pooled Data from California

Purpose: Previous research has shown that Asian Americans are less likely to receive recommended clinical preventive services especially for cancer compared with non-Hispanic whites. Health insurance expansion has been recommended as a way to increase use of these preventive services. This study examines the extent to which utilization of preventive services by Asians overall and by ethnicity compared with non-Hispanic whites is moderated by health insurance. Methods: Data from the California Health Interview Survey (CHIS) was used to examine preventive service utilization among non-Hispanic whites, Asians, and Asian subgroups 50-64 years of age by insurance status. Six waves of CHIS data from 2001 to 2011 were combined to allow analysis of Asian subgroups. Logistic regression models were run to predict the effect of insurance on receipt of mammography, colorectal cancer (CRC) screening, and flu shots among Asians overall and by ethnicity compared with whites. Results: Privately insured Asians reported significantly lower adjusted rates of mammography (83.1% vs. 87.6%) and CRC screening (54.7% vs. 59.4%), and higher rates of influenza vaccination (48.7% vs. 38.5%) than privately insured non-Hispanic whites. Adjusted rates of cancer screening were lower among Koreans and Chinese for mammography, and lower among Filipinos for CRC screening. Conclusion: This study highlights the limitations of providing insurance coverage as a strategy to eliminate disparities for cancer screening among Asians without addressing cultural factors.

Cancer Control Continuum in Korean American Community Newspapers: What Is the Association with Source Nationality-US vs. Korea?

Prior research suggests that cancer information obtained from Korean American community media, which are the primary health information sources among the population, does not connect to Korean Americans' increased cancer knowledge or cancer protective/detective behavior. We aim to identify the reason by analyzing cancer type, cancer control continuum, and cancer topic presented in Korean American community newspapers. The nationality of news source, US and Korea, and its association with the cancer coverage were examined. We found that among articles that cited any source, nearly one third used a source from Korea. The source nationality was associated with cancer coverage. In particular, cancer risk factors and screening were more likely to be discussed when a US source was cited as compared to when no source was cited. Korean sources were never or rarely observed in articles focusing on a few cancer sites (e.g., breast and prostate, which Korean Americans have higher risks compared to native Koreans), cancer preventive behaviors (diet, physical activity, no smoking), and specific cancer detection methods (mammogram, pap-smear). We suggest Korean American media to reflect the cancer priority and information needs among Korean Americans, which are varied from native Koreans, and to acknowledge the differences in cancer prevention and detection guidelines between the U.S. and Korean healthcare system. Also, the U.S. government should disseminate cancer screening and prevention guidelines, customized to racial/ethnic groups' cancer prevalence and communication preference.

The impact of cancer information online on cancer fatalism: education and eHealth literacy as moderators

One critical yet understudied concept associated with cancer information is cancer fatalism, i.e. deterministic thoughts about the cause of cancer, the inability to prevent it and the unavoidability of death upon diagnosis. The aim of this study is to understand how information seeking about cancer online influences cancer fatalism and whether and to what extent education and eHealth literacy moderate the relationship between them. Findings from an online survey of a nationally representative sample in the United States (N = 578) showed differential impacts of using the internet to search for information about cancer among the more and the less educated. For the less educated, more exposure to information about cancer via medical and health websites led to an increased level of cancer fatalism, whereas among the more educated, greater exposure lowered cancer fatalism. These differences were explained by the fact that the more educated were equipped with a higher level of eHealth literacy skills than the less educated. Findings show that only when one has necessary skills to apply digital resources can those resources help mitigate cancer fatalism. We suggest the need to enhance eHealth literacy skills among the less educated to reduce cancer fatalism.

Familiarity, Navigation, and Comprehension: Key Dimensions of Health Literacy in Pap Test Use among Korean American Women

Health literacy consists of multiple dimensions such as print and oral literacy or numeracy. Different dimensions of health literacy may have more salient impact on certain health behaviors and outcomes. Yet, evidence is limited regarding which dimensions particularly affect cervical cancer screening. The objective of this study was to examine the role of different dimensions of health literacy in cervical cancer screening among Korean American women. We used baseline data obtained from 560 Korean American women in a community-based health literacy-focused intervention study. Backward stepwise logistic regression analysis revealed that familiarity (adjusted odds ratio [AOR] = 1.20, 95% confidence interval [CI] = 1.11-1.31) and navigational health literacy (AOR = 1.10, 95% CI = 1.04-1.16) were associated with lifetime Pap test use and comprehension (AOR = 1.08, 95% CI = 1.02-1.14) with triennial Pap test screening. Prior exposure to healthcare settings and knowing how to navigate the healthcare system were more important than other health literacy dimensions for lifetime Pap test use. Understanding cancer screening-related words was most relevant to triennial Pap test use. In addition to addressing system factors such as insurance and physicians' recommendations, interventions to increase Pap test screening targeted at Korean American women are needed to address certain dimensions of health literacy such as familiarity, navigation, and comprehension.

Factors Associated with Breast Cancer Screening among Korean American Women in California: Results from the California Health Interview Survey 2015–2016

Background: Few studies have examined preventive lifestyle behaviors and breast cancer (BC) screening behaviors simultaneously to determine whether BC screening behaviors are associated with preventive lifestyle behaviors. The purposes of this study are to (a) describe BC screening utilization and preventive lifestyle behaviors and (b) examine factors associated with BC utilization among Korean American (KA) women. Methods: Data from the 2015–2016 California Health Interview Survey were analyzed. Survey-weighted adjusted logistic regressions were used to determine whether preventive lifestyle behaviors and characteristics of KA women 50 years of age and older at the time of the survey were associated with obtaining mammograms. Results: Most participants were born outside of the US and had lived in the US for 15 years or more at the time of the survey. This study found that KA women who were 50–64 years old had 38 times greater odds of having ever had a mammogram and a 13 times greater odds of having a recent mammogram than those 65 and older. KA women who walked at least 10 minutes per week for transportation and leisure purposed were 61 times more likely to have ever had a mammogram than those who did not walk. Conclusion: This study provides important perspectives on associations of BC screening behaviors and preventive life-style behaviors, especially walking. Future research should be conducted to better understand the association between BC screening and preventive life-style behaviors and to develop feasible interventions to improve BC screening behaviors among KA women, particularly elderly and physically inactive ones.

Association Between Neighborhood Cohesion and Cancer Screening Utilization in Chinese American Older Adults

This study aims to examine the association between neighborhood cohesion and cancer screening utilization in a community-dwelling Chinese American older population. Data were drawn from the Population Study of Chinese Elderly including 3159 Chinese American older adults aged 60 and above in the greater Chicago area. Cancer screening utilization was assessed by asking whether participants had undergone colon, breast, cervical, or prostate cancer screening. Neighborhood cohesion was measured through six questions. Logistic regression analysis showed that greater neighborhood cohesion was associated with higher likelihood of utilizing a mammogram (OR 1.32, 95% CI 1.14-1.52), a Pap test (OR 1.22, 95% CI 1.06-1.41), but not of a blood stool test (OR 1.10, 95% CI 0.98-1.23), a colonoscopy (OR 1.05, 95% CI 0.94-1.17), and a PSA test (OR 1.13, 95% CI 0.95-1.34). This study suggests positive associations between neighborhood cohesion and breast and cervical cancer screening utilization among a Chinese American older population.

Ethnic density and cancer: A review of the evidence

Accumulating data suggest that factors in the social environment may be associated with cancer-related outcomes. Ethnic density, defined as the proportion of racial/ethnic minority individuals residing in a given geographic area, is 1 of the most frequently studied social environment factors, but studies on ethnic density and cancer have yielded inconsistent findings. Thus, the objective of the current review was to summarize the extant data on ethnic density and cancer-related outcomes (cancer risk, stage at diagnosis, and mortality) with the aim of identifying pathways by which ethnic density may contribute to outcomes across populations. In general, the findings indicated an association between ethnic density and increased risk for cancers of infectious origin (eg, liver, cervical) but lower risk for breast and colorectal cancers, particularly among Hispanic and Asian Americans. Hispanic ethnic density was associated with greater odds of late-stage cancer diagnosis, whereas black ethnic density was associated with greater mortality. In addition, this review highlights several methodological and conceptual issues surrounding the measurement of ethnic neighborhoods and their available resources. Clarifying the role of neighborhood ethnic density is critical to developing a greater understanding of the health risks and benefits accompanying these environments and how they may affect racial and ethnic disparities in cancer-related outcomes.

Patterns and correlates of cervical cancer screening initiation in a large integrated health care system

BACKGROUND

The latest 2012 US Preventive Services Task Force cervical cancer screening guidelines recommended screening initiation at age 21 years. Little is known about the cervical cancer screening initiation practices in the community and whether there are critical gaps with respect to adherence to current clinical guidelines. Despite an overall decline in cervical cancer incidence across women of all ages, the incidence rate has not declined among 24-25 year olds between 2000 (2.79 per 100,000) and 2013 (2.93 per 100,000). Thus, it is important to understand cervical cancer screening initiation in young women and how woman- and provider-level factors affect the timing of screening initiation to identify areas for improving cervical cancer prevention.

OBJECTIVE

We examined patterns and correlates of cervical cancer screening initiation among women turning age 21 years in a large community-based practice.

STUDY DESIGN

Female members of Kaiser Permanente Southern California who turned age 21 years (baseline) during 2013-2015 and had not previously received a Papanicolaou test were included. Cervical cancer screening initiation through October 2016 was captured using electronic health records. Incidence rate and cumulative incidence of screening initiation was calculated. Associations between patient and provider characteristics and screening initiation were evaluated using multivariable Cox models.

RESULTS

A total of 38,257 women were included and the Papanicolaou screening initiation rate was 44 per 100 person-years during the study period. Approximately 40% initiated screening within 1 year after turning age 21 years. In multivariable analyses, Asian/Pacific Islanders (hazard ratio, 0.91; confidence interval, 0.86-0.96 compared with non-Hispanic whites); Medicaid enrollees (hazard ratio, 0.90; confidence interval, 0.83, 0.97); those whose primary language is not English (hazard ratio, 0.71; confidence interval, 0.67, 0.75); those who have a historical inpatient visit, primary care physician in pediatrics, internal medicine, or another specialty compared with family practice; and have a male rather than female primary care physician (hazard ratio, 0.46; confidence interval, 0.36, 0.57) less often initiated screening. On the other hand, those who used other preventive services such as getting a human papilloma virus and influenza vaccination and those with a history of pregnancy, contraception use, and sexually transmitted infections more often had timely screening initiation.

CONCLUSION

Less than half of the women insured for preventative services initiated screening at age 21 years. Strategies to improve adherence to screening initiation guidelines should consider a tailored approach for at-risk subgroups and addressing initiation challenges associated with male physicians.
