Colorectal cancer screening: low health literacy and limited English proficiency among Asians and Whites in California

Readability of online patient education materials for shoulder instability surgery in English and Spanish

BACKGROUND

Online patient education materials (OPEMs) exist to inform patient medical decisions, yet the average adult in the United States reads at an eighth-grade level and 50% of Medicaid patients read at or below a fifth-grade level. To appropriately meet US health literacy needs, the American Medical Association and National Institutes of Health recommend that patient education materials not exceed a sixth-grade level. The purpose of this study was to assess and compare the readability of English and Spanish online patient education materials pertaining to shoulder instability surgery.

METHODS

Google searches of the terms "shoulder instability surgery" and "cirugía de inestabilidad de hombro'' were conducted to include 25 eligible online patient education materials OPEMs per language. English OPEM readability was calculated using Flesch-Kincaid Grade Level, Flesch Reading Ease, Flesch Reading Ease Grade Level, Gunning-Fog Index, Coleman-Liau Index, and Simple Measure of Gobbledygook. Spanish OPEM readability was assessed using Fernandez-Huerta Index (FHI) (the Spanish equivalent of Flesch Reading Ease), FHI Grade Level, Gutiérrez de Polini's Fórmula de comprensibilidad, and INFLESZ.

RESULTS

Readability index analysis revealed that the mean Flesch Reading Ease of English online patient education materials was significantly lower than the mean FHI of Spanish online patient education materials. English materials were also found to be written at a significantly higher grade level than Spanish materials.

CONCLUSIONS

Shoulder instability surgery online patient education materials in both English and Spanish are written at higher reading levels than recommended by the American Medical Association and National Institutes of Health, though Spanish online patient education materials were more readable on average.

Associations of social vulnerability with truncal and extremity melanomas in the United States

BACKGROUND

Prior studies in social determinants (SDoH) of truncal-extremity melanomas (TEM) have analyzed race, income, and environmental factors relative to their effect on health disparities. However, they are limited by the narrow scopes of SDoH and study population, while lacking analyses of interrelational contribution of SDoH on TEM disparities.

METHODS

This retrospective cohort study of adult TEM patients (1975-2017) assessed linear regression trends in months of survival, as well as logistic regression trends in advanced presenting stage, surgery, and chemotherapy receipt across TEM subtypes with increasing overall social vulnerability and vulnerability in 15 SDoH variables grouped into socioeconomic status (SES), minority-language status (ML), household composition (HH), and housing-transportation (HT) themes measured by the SVI. SVI measures are ranked/compared across all US counties for relative vulnerability in a specific SDH and their total composite while accounting for sociodemographic-regional differences.

RESULTS

Across 325 760 TEM patients, increasing overall social vulnerability demonstrated significant decreases in the survival period for 7/13 TEM histology types (p < 0.001), with relative decreases in the survival period as high as 44.0% (67.0-37.5 months) for epithelioid cell. SES and HH were the highest-magnitude contributors to these overall trends. For many patients with TEM, increased odds of advanced presenting stage (highest with acral-lentiginous: odds ratio [OR], -1.18; 95% confidence interval [CI], 1.02-1.36), decreased odds of indicated surgery receipt (lowest with amelanotic, 0.79; 0.71-0.87), and increased odds of indicated chemotherapy (highest with melanoma in giant nevi: 1.50; 1.01-2.44) were observed; SES and ML followed by HH and HT contributed to these trends.

CONCLUSIONS

There were detriments in TEM care & prognosis in the United States with increasing social vulnerability. Identifying which SDH quantifiably are associated more with disparities in interrelational, real-world contexts is important to provide nuance to inform future research and initiatives to address TEM disparity.

Impact of English Proficiency on Health Literacy in Older Korean Immigrants: Mediating Effects of Social Support and Acculturation

Limited English proficiency (LEP) is one of the most influencing factors of personal health literacy (PHL) in the older immigrant population. Over the years, the proportion of older Korean immigrants with LEP has not improved and it is still noted as a major barrier to PHL. Therefore, organizational approaches are needed to enhance the PHL of older immigrants with LEP. This study aims to find the mediating effect of social support and acculturation between LEP and PHL by conceptualizing social support and acculturation as an organizational health literacy strategy. Data from 244 older Korean immigrants living in the states of Alabama and Georgia, USA, were used to conduct the study. Korean version of the Multidimensional Scale of Perceived Social Support (MSPSS), East Asian Acculturation Measure (EAAM), and Health Literacy Survey-12 Questionnaires (HLS-Q12) were used to measure the variables. The path analysis was conducted to find the serial mediation effects of social support and acculturation. The results showed that 77.5% of the participants reported not having fluent English proficiency. English proficiency (β =- 0.21, p = 0.007), social support (β = 0.17, p = 0.004), and acculturation (β = 0.18, p = 0.011) significantly predicted the PHL, and social support (β = 0.04, p = 0.028) and acculturation (β = 0.14, p < 0.001) mediated the relationship between LEP and PHL. Discussion: Health-related organizations and communities are encouraged to provide external social support and acculturation opportunities to enhance PHL in older Korean immigrants with LEP.

The Impact of Limited English Proficiency on Healthcare Access and Outcomes in the U.S.: A Scoping Review

A majority of individuals with limited English proficiency (LEP) in the U.S. are foreign-born, creating a complex intersection of language, socio-economic, and policy barriers to healthcare access and achieving good outcomes. Mapping the research literature is key to addressing how LEP intersects with healthcare. This scoping review followed PRISMA-ScR guidelines and included PubMed/MEDLINE, CINAHL, Sociological Abstracts, EconLit, and Academic Search Premier. Study selection included quantitative studies since 2000 with outcomes specified for adults with LEP residing in the U.S. related to healthcare service access or defined health outcomes, including healthcare costs. A total of 137 articles met the inclusion criteria. Major outcomes included ambulatory care, hospitalization, screening, specific conditions, and general health. Overall, the literature identified differential access to and utilization of healthcare across multiple modalities with poorer outcomes among LEP populations compared with English-proficient populations. Current research includes inconsistent definitions for LEP populations, primarily cross-sectional studies, small sample sizes, and homogeneous language and regional samples. Current regulations and practices are insufficient to address the barriers that LEP individuals face to healthcare access and outcomes. Changes to EMRs and other data collection to consistently include LEP status and more methodologically rigorous studies are needed to address healthcare disparities for LEP individuals.

Anxiety and Health Literacy Levels of Patients Undergoing Colonoscopy

This descriptive, correlational study was conducted to determine the anxiety and health literacy levels of patients undergoing colonoscopy and the variables affecting them. The study population consisted of individuals who presented for colonoscopy to the endoscopy department of a state hospital. The sample consisted of 160 individuals who met the inclusion criteria. Three data collection tools (Identifying Information Form, State-Trait Anxiety Inventory, and Health Literacy Scale) were used to determine anxiety and health literacy levels. Findings show that the state-trait anxiety of individuals who would undergo colonoscopy for the first time was moderate, and their health literacy scores were inadequate, problematic, and weak. There was a positive and significant relationship between patients' anxiety and health literacy levels. Variables such as age, gender, marital status, education level, employment status, disease-related symptoms, a family history of cancer, and fear of colonoscopy influenced anxiety and health literacy. Based on these findings, we recommend that individuals' anxiety and health literacy status be determined before a colonoscopy procedure to improve gastroenterology nurses' management of these patients.

Colon Cancer Disparities in Stage at Presentation and Time to Surgery for Asian Americans, Native Hawaiians, and Pacific Islanders: A Study with Disaggregated Ethnic Groups

BACKGROUND

Vast differences in barriers to care exist among Asian American, Native Hawaiian, and Pacific Islander (AANHPI) groups and may manifest as disparities in stage at presentation and access to treatment. Thus, we characterized AANHPI patients with stage 0-IV colon cancer and examined differences in (1) stage at presentation and (2) time to surgery relative to white patients.

PATIENTS AND METHODS

We assessed all patients in the National Cancer Database (NCDB) with stage 0-IV colon cancer from 2004 to 2016 who identified as white, Chinese, Japanese, Filipino, Native Hawaiian, Korean, Vietnamese, Laotian, Hmong, Kampuchean, Thai, Asian Indian or Pakistani, and Pacific Islander. Multivariable ordinal logistic regression defined adjusted odds ratios (AORs), with 95% confidence intervals (CI), of (1) patients presenting with advanced stage colon cancer and (2) patients with stage 0-III colon cancer receiving surgery at ≥ 60 days versus 30-59 days versus < 30 days postdiagnosis, adjusting for sociodemographic/clinical factors.

RESULTS

Among 694,876 patients, Japanese [AOR 1.08 (95% CI 1.01-1.15), p < 0.05], Filipino [AOR 1.17 (95% CI 1.09-1.25), p < 0.001], Korean [AOR 1.09 (95% CI 1.01-1.18), p < 0.05], Laotian [AOR 1.51 (95% CI 1.17-1.95), p < 0.01], Kampuchean [AOR 1.33 (95% CI 1.04-1.70), p < 0.01], Thai [AOR 1.60 (95% CI 1.22-2.10), p = 0.001], and Pacific Islander [AOR 1.41 (95% CI 1.20-1.67), p < 0.001] patients were more likely to present with more advanced colon cancer compared with white patients. Chinese [AOR 1.27 (95% CI 1.17-1.38), p < 0.001], Japanese [AOR 1.23 (95% CI 1.10-1.37], p < 0.001], Filipino [AOR 1.36 (95% CI 1.22-1.52), p < 0.001], Korean [AOR 1.16 (95% CI 1.02-1.32), p < 0.05], and Vietnamese [AOR 1.55 (95% CI 1.36-1.77), p < 0.001] patients were more likely to experience greater time to surgery than white patients. Disparities persisted when comparing among AANHPI subgroups.

CONCLUSIONS

Our findings reveal key disparities in stage at presentation and time to surgery by race/ethnicity among AANHPI subgroups. Heterogeneity upon disaggregation underscores the importance of examining and addressing access barriers and clinical disparities.

Development and psychometric validation of the Colorectal Cancer Literacy Scale-Uruguay Version

Colorectal cancer is a leading cause of cancer death in Uruguay, yet less than half of the eligible population is up to date with screenings. Research is hampered because no measures exist to assess psychosocial factors that influence screening decisions in this population. To address this gap, we report on the development and psychometric validation of the Colorectal Cancer Literacy Scale-Uruguay Version, a scale based on the health literacy model. We developed an item pool based on the extant literature, obtained feedback from experts, and conducted focus groups with community participants and health care providers. After revision, we conducted a psychometric validation with a national community sample of 405 participants. Through an exploratory factor analysis, we identified four factors that were collapsed into two for theoretical and pragmatic reasons, representing (a) disposition toward cancer prevention and (b) attitudes, beliefs, and emotions about cancer. A third factor, knowledge about colorectal cancer, was examined separately given its distinct focus. Subsequently, we conducted a confirmatory factor analysis with the remaining sample participants using Rasch measurement theory for validation purposes and to further assess the scales' psychometric properties. The resulting 44-item scale presented a good model fit with adequate EAP reliabilities and good initial discriminant validity. Further criterion-related validity analyses should be performed when additional measures are available. The Colorectal Cancer Literacy Scale-Uruguay Version is a theoretically based measure that can bring to light barriers and facilitative factors in an underscreened population at risk. Implications for theory, research, and practice are discussed.

The Influence of Social Determinants on Cancer Screening in a Medicaid Sample

INTRODUCTION

Little attention has been paid to the influence of individually measured social determinants of health on cancer screening tests in the Medicaid population.

METHODS

Analysis was conducted on 2015-2020 claims data from a subgroup of Medicaid enrollees from the District of Columbia Medicaid Cohort Study (N=8,943) who were eligible for colorectal (n=2,131), breast (n=1,156), and cervical cancer (n= 5,068) screening. Participants were grouped into four distinct social determinants of health groups on the basis of their responses to social determinants of health questionnaire. This study estimated the influence of the four social determinants of health groups on the receipt of each screening test using log-binomial regression adjusted for demographics, illness severity, and neighborhood-level deprivation.

RESULTS

The receipt of cancer screening tests was 42%, 58%, and 66% for colorectal, cervical, and breast cancer, respectively. Those in the most disadvantaged social determinants of health group were less likely to receive a colonoscopy/sigmoidoscopy than those in the least disadvantaged one (adjusted RR=0.70, 95% CI=0.54, 0.92). The pattern for mammograms and Pap smears was similar (adjusted RR=0.94, 95% CI=0.80, 1.11 and adjusted RR=0.90, 95% CI=0.81, 1.00, respectively). In contrast, participants in the most disadvantaged social determinants of health group were more likely to receive fecal occult blood test than those in the least disadvantaged one (adjusted RR=1.52, 95% CI=1.09, 2.12).

CONCLUSIONS

Severe social determinants of health measured at the individual level are associated with lower cancer preventive screening. A targeted approach that addresses the social and economic adversities that affect cancer screening could result in higher preventive screening rates in this Medicaid population.

Characteristics of Cancer Hospitals with Written Language Access Policies

Patients with limited English proficiency receive worse care due to communication barriers. Little is known about which cancer hospitals have written language access policies addressing bilingual clinicians. We conducted a cross-sectional survey of healthcare organizations, matching survey data to American Hospital Association Survey and American Community Survey data. We analyzed characteristics associated with hospitals having bilingual clinician policies. The response rate was 71% (127/178). Many hospitals (53 [42%]) did not have written policies on bilingual clinicians. Having bilingual clinicians available at the hospital was associated with having a written policy on bilingual clinicians, while being an NCORP site was associated with not having a written policy on bilingual clinicians. Patient demographic characteristics were not associated with hospitals having written policies on bilingual clinicians. A substantial proportion of cancer hospitals do not have policies that cover language use by bilingual clinicians, particularly at NCORP sites. Having written policies on bilingual clinicians has the potential to mitigate cancer disparities by facilitating accountability, improving communication, and reducing errors.

Colorectal cancer screening in a safety-net health system: The intersectional impact of race, ethnicity, language, and mental health

Though rates of colorectal cancer (CRC) screening continue to improve with increased advocacy and awareness, there are numerous disparities that continue to be defined within different health systems and populations. We aimed to define associations between patients' socio-demographic characteristics and CRC screening in a well-resourced safety-net health system. A retrospective review was performed from 2018 to 2019 of patients between 50 and 75-years-old who had a primary care visit within the last two years. Numerous patient characteristics were extracted from the medical record, including self-reported race, self-reported ethnicity, insurance, preferred language, severe mental health diagnoses (SMHD), and substance use disorder (SUD). Multivariate logistic regression assessed characteristics associated with CRC screening. Of 22,145 included patients, 16,065 (72.5%) underwent CRC screening. <40% of the population was White or of North American/European ethnicity and 38% had limited English proficiency. Hispanic patients had the highest screening rate while White patients had the lowest among races (78.1% vs 68.5%, respectively). White patients had higher rates of SMHD and SUD (p < 0.001). In multivariable analysis, most other races (Black, Asian, and Hispanic), ethnicities, and languages had significantly higher odds of screening, ranging from 20% to 55% higher, when White, North American/European, English-speakers are used as reference. In a well-resourced safety-net health system, patients who were non-White, non-North American/European, and non-English-speaking, had higher odds of CRC screening. This data from a unique health system may better guide screening outreach and implementation strategies in historically under-resourced communities, leading to strategies for equitable colorectal cancer screening.

Disparities in Screening for Colorectal Cancer Based on Limited Language Proficiency

BACKGROUND

This study analyzes the association between limited language proficiency and screening for colorectal cancer.

METHODS

This is a retrospective cohort study from the 2015 sample of the National Health Interview Survey database utilizing univariate and multivariate regression analysis. The study population includes subjects between 50 and 75 years of age. The main outcome analyzed was rates of screening colonoscopies between limited English-language proficiency (LEP) subjects and those fluent in English. Secondary outcomes included analysis of baseline, socioeconomic, access to health care variables, and other modalities for colorectal cancer screening between the groups.

RESULTS

Incidence of limited language proficiency was 4.8% (n = 1978, count = 4 453 599). They reported lower rates of screening colonoscopies (61% vs 34%, P < .001), less physician recommendation for a colonoscopy (87 vs 60%, P < .001), fewer polyps removed in the previous 3 years (24% vs 9.1%; P < .001), and fewer fecal occult blood samples overall (P < .001). Additionally, Hispanic non-LEP subjects have higher rates of colonoscopies compared to those with language barriers (50% vs 33%, P < .001). On multivariate analysis, LEP was associated with a lower likelihood to have a screening colonoscopy (OR .67 95% CI .49-.91). A second regression model with "Spanish language" and "other language" variables included, associated Spanish speakers with a lower likelihood for a screening colonoscopy (OR .71 95% CI .52-.97) when controlling for baseline, socioeconomic, and access to health care covariates.

DISCUSSION

Patients with limited English-language proficiency are associated with lower rates of screening for colorectal cancer, in particular the Spanish speaking subgroup.

The association between adherence to cancer screening programs and health literacy: A systematic review and meta-analysis

The effectiveness of a cancer screening program relies on its adherence rate. Health literacy (HL) has been investigated among the factors that could influence such participation, but the findings are not always consistent. The aim of this meta-analysis was to summarize the evidence between having an adequate level of HL (AHL) and adherence to cancer screening programs. PubMed, Scopus, and Web of Science were searched. Cross-sectional studies, conducted in any country, that provided raw data, unadjusted or adjusted odds ratio (OR) on the associations of interest were included. The quality of the studies was assessed with the Newcastle-Ottawa Scale. Inverse-variance random effects methods were used to produce pooled ORs and their associated confidence interval (CI) stratified by time interval (e.g., undergoing screening in the last period, or at least once during lifetime) for each cancer type, considering unadjusted and adjusted estimates separately. A sensitivity analysis was performed for those studies providing more estimates. Overall, 15 articles of average-to-good quality were pooled. We found a significant association between AHL and higher screening participation for breast, cervical and colorectal cancer, independently of other factors, both overall (N = 7, aOR = 1.73; 95% CI: 1.27-2.36; N = 3, aOR = 1.64; 95% CI: 1.30-2.09; and N = 5, aOR = 1.25, 95% CI: 1.12-1.39, respectively) and in most time-stratified analyses. The sensitivity analyses confirmed these results. Health literacy seems to be critical for an effective cancer prevention. Given the high prevalence of illiterate people across the world, a long-term action plan is needed.

Experience and lessons learned from multi-modal internet-based recruitment of U.S. Vietnamese into research

BACKGROUND

Asian-Americans are one of the most understudied racial/ethnic minority populations. To increase representation of Asian subgroups, researchers have traditionally relied on data collection at community venues and events. However, the COVID-19 pandemic has created serious challenges for in-person data collection. In this case study, we describe multi-modal strategies for online recruitment of U.S. Vietnamese parents, compare response rates and participant characteristics among strategies, and discuss lessons learned.

METHODS

We recruited 408 participants from community-based organizations (CBOs) (n = 68), Facebook groups (n = 97), listservs (n = 4), personal network (n = 42), and snowball sampling (n = 197). Using chi-square tests and one-way analyses of variance, we compared participants recruited through different strategies regarding sociodemographic characteristics, acculturation-related characteristics, and mobile health usage.

RESULTS

The overall response rate was 71.8% (range: 51.5% for Vietnamese CBOs to 86.6% for Facebook groups). Significant differences exist for all sociodemographic and almost all acculturation-related characteristics among recruitment strategies. Notably, CBO-recruited participants were the oldest, had lived in the U.S. for the longest duration, and had the lowest Vietnamese language ability. We found some similarities between Facebook-recruited participants and those referred by Facebook-recruited participants. Mobile health usage was high and did not vary based on recruitment strategies. Challenges included encountering fraudulent responses (e.g., non-Vietnamese). Perceived benefits and trust appeared to facilitate recruitment.

CONCLUSIONS

Facebook and snowball sampling may be feasible strategies to recruit U.S. Vietnamese. Findings suggest the potential for mobile-based research implementation. Perceived benefits and trust could encourage participation and may be related to cultural ties. Attention should be paid to recruitment with CBOs and handling fraudulent responses.

Social Determinants, Health Literacy, and Disparities: Intersections and Controversies

This article synthesizes what is known about the relationship between social disadvantage and measures of health literacy (HL), and reviews the research examining whether low HL is an explanatory factor connecting social disadvantage, health outcomes, and health disparities. Written from a United States perspective, this article offers a novel conceptual framework that presents how the social determinants of health might interact with HL to result in health disparities. The framework articulates relationships that reflect public health pathways and health care pathways, which include their related health literacies. The article continues with several cautionary statements based on the inherent limitations of current HL research, including problems and concerns specific to the attribution of HL as an explanatory factor for extant socioeconomic and racial/ethnic health disparities. The article closes with recommendations regarding future research directions. [HLRP: Health Literacy Research and Practice. 2021;5(3):e233–e243.]

Association between health literacy and colorectal cancer screening behaviors in adults in Northwestern Turkey

BACKGROUND

In this study, aimed to determine the frequency of participation in colorectal cancer (CRC) screenings, the factors affecting participation and the association between CRC screening behaviors and health literacy (HL).

METHODS

This community-based cross-sectional study was carried out with 408 people residing in Kirklareli, a province in Northwestern Turkey, between August and November 2019.

RESULTS

CRC screenings participation prevalence was 21.1%. Of them, 17.2% participated in fecal occult blood tests (FOBT) screenings, 7.6% participated in colonoscopy screenings, and 86.5% had inadequate or limited-problematic HL. According to the multivariate logistic regression analysis, the likelihood of not participating in CRC screenings was high in the participants who worked at a paid job (OR: 3.001, 95% CI: 1.018-8.850), who did not do any physical activity regularly (OR: 2.516, 95% CI: 1.251-5.060), who were not aware of the presence of an early diagnosis test for CRC (OR: 32.613, 95% CI: 13.338-79.742), who did not have a person having had CRC screening in their immediate environment (OR: 3.562, 95% CI: 1.752-7.240) and who had sufficient or excellent HL (OR: 3.324, 95% CI: 1.128-9.796). According to adjusted for some characteristics, there was no significant association between participation in CRC screenings and THLS-sub-dimensions and THLS-processes (P>0.05).

CONCLUSIONS

Participation in CRC screenings was low, and those with a high HL level were more likely not to participate in CRC screenings. Working status, knowledge and awareness levels affected the participation to CRC screenings. To encourage people to participate in screenings and to improve their HL, awareness-raising attempts for target groups should be increased.

Far from black and white: Role of race, health literacy, and socioeconomic factors in the presentation of acute diverticulitis

BACKGROUND

Racial discrepancies in treatment and outcomes of acute diverticulitis have been observed, yet underlying factors are poorly understood. We aimed to identify racial inequalities in health literacy among patients hospitalized with acute diverticulitis and characterize factors associated with more severe presentation.

METHODS

We performed retrospective cohort analysis of 947 Black or White patients admitted with acute diverticulitis at a quaternary referral center from January 2009 through September 2019. Health literacy was determined by the validated Brief Health Literacy Screening, and socioeconomic status was defined by area deprivation index, a composite of multiple neighborhood socioeconomic deprivation measures. The primary outcome was severity of disease presentation represented by systemic inflammatory response syndrome criteria; secondary outcomes included intensive care unit admission, length of stay, and invasive interventions.

RESULTS

Among all study participants, 121 (12.8%) self-identified as Black. Overall, 140 (14.8%) patients had inadequate health literacy, and 495 (52.3%) had area deprivation index greater than the national median. There was no association between race or area deprivation index and health literacy. A total of 340 (35.9%) patients met criteria for systemic inflammatory response syndrome, and 88 (9.3%) underwent an intervention; median length of stay was 3.5 days. Race, health literacy, and area deprivation index were not significantly associated with outcomes (P > .05).

CONCLUSION

Among patients with acute diverticulitis, no difference in severity of presentation by race, health literacy, or area deprivation index was observed. These findings suggest that differences in presentation of acute diverticulitis may not be driven by these social factors. Future studies should include considerations of clinical characteristics of acute diverticulitis, such as the role of access and underuse of healthcare resources.

Disparities Among Limited English Proficient Patients in Colon Cancer Screening with Multi-target DNA Stool Test

Racial and language minority groups in the U.S. are at a higher risk for morbidity and mortality from colorectal cancer (CRC), partially due to lower screening rates. This is a retrospective cohort study comparing successful multi-target stool DNA test (mt-sDNA) test completion among patients with limited English proficiency (LEP) and English proficient (EP) patients, from 2015 to 2018. Patients with LEP were frequency matched to EP patients by age at a 3:1 ratio. The percentage of mt-sDNA tests without useful results was 53% among patients with LEP compared to 29% among EP patients (p < 0.0001). The median number of days from order placement to test completion was 62.5 among patients with LEP compared to 33 for EP patients (p = 0.003). This study demonstrates a significant disparity in CRC screening completion using the mt-sDNA test among populations with LEP, which may widen existing disparities in CRC mortality.

Effects of health literacy interventions on health-related outcomes in socioeconomically disadvantaged adults living in the community: a systematic review

OBJECTIVES

The objectives of this review were: i) to identify and synthesize the best available evidence on the effectiveness on health-related outcomes of health literacy interventions for enabling socioeconomically disadvantaged people living in the community to access, understand, appraise and apply health information; and ii) to identify components of health literacy interventions associated with improved health-related outcomes.

INTRODUCTION

Health literacy is defined as a person's competence in accessing, understanding, appraising and applying health information in order to make sound health decisions. A high level of health literacy is positively related to better health outcomes. However, nearly half of the American and European populations have low health literacy levels. Socioeconomically disadvantaged groups in particular present with the weakest health literacy levels, suggesting that differences in health literacy levels contribute to health disparities. Therefore, there is a need to understand the conditions under which health literacy interventions aiming at improving health-related outcomes among socioeconomically disadvantaged people can be implemented.

INCLUSION CRITERIA

This review considered studies on socioeconomically disadvantaged adults living in the community identified using the socially stratifying PROGRESS factors (Place of residence, Race/ethnicity, Occupation, Gender, Religion, Education, Socioeconomic status, Social capital).This review considered studies evaluating the following interventions: i) targeting health literacy based on either a clinical and/or a public health approach, ii) delivered at the individual, interpersonal, community or societal level, iii) delivered by any healthcare/social work professional, and iv) using a single or multicomponent strategy. The comparator was no treatment, standard care or a variation of the intervention. All randomized and non-randomized controlled trials as well as quasi-experimental designs were included. Outcomes considered were: i) health-related quality of life and health-related outcomes, ii) health behavior outcomes, and iii) outcomes related to the access and use of healthcare services.

METHODS

A three-step strategy was conducted for primary research published up to May 2018 across seven databases without any language restriction. A search for gray literature was also conducted. Titles and abstracts were screened for assessment against the inclusion criteria. Studies that met the inclusion criteria were retrieved in full and then assessed in detail against the inclusion criteria. Critical appraisal was undertaken using the standardized critical appraisal instruments from JBI. Data were extracted from included studies using standardized data extraction tools from JBI. A meta-analysis was not possible; findings have been presented in a narrative form.

RESULTS

Twenty-one studies were included in the review. Three studies addressed the health literacy competency of understanding health information, and 18 addressed the competency of applying health information. Thirteen studies were found as effective based on a variety of health-related outcomes (mainly clinical outcomes), preventive health practices and behaviors, and health-promoting behaviors. Results enabled identification of some effective intervention operational components, including cultural appropriateness, tailoring, skills building, goal setting and active discussions. Multi-faceted interventions, combining both an information transfer medium and contact with an interventionist, appear to be more effective than single modality interventions. The use of an appropriate theoretical foundation is also an important factor for successful interventions.

CONCLUSION

To improve health-related outcomes among socioeconomically disadvantaged people, health literacy interventions are more likely to be successful if they are theory-based, are multi-faceted and use person-centered operational components such as cultural appropriateness, tailoring, skills building, goal setting and active discussions.

Electronic Tools to Bridge the Language Gap in Health Care for People Who Have Migrated: Systematic Review

BACKGROUND

People who have migrated or with a language barrier may face significant hurdles in accessing health care. Some apps have been specifically developed to facilitate the dialogue between health care professionals and people who have migrated who have low-level language proficiency or to promote health among people who have migrated.

OBJECTIVE

We conducted a systematic review to investigate development, acceptability, and effectiveness of these types of apps.

METHODS

We conducted a search of PubMed, Scopus, and Embase databases. We included all study designs (qualitative, quantitative, mixed) reporting development, evaluation of efficacy, or acceptability of apps facilitating dialogue with a health professional or promoting health for people who have migrated, minorities, or tourists with a language barrier, using any outcome. Two researchers selected the studies independently. We collected general information about the app, information about health literacy and cultural adaptation, information about the development of the app, evidence on acceptability or efficacy, and information on app use. Data were collected by 2 researchers independently and results were reviewed to verify agreement and reported according to PRISMA (Preferred Reporting Items for Systematic Review and Meta-analysis).

RESULTS

Positive results for translation apps included better communication, but with possible limitations, and reduced consultation time. Positive results for health promotion apps included improved quality of life and better management of chronic illnesses.

CONCLUSIONS

Overall, the apps had good levels of acceptability, though only half had their efficacy evaluated. In those evaluations, the endpoints were mostly related to reported behavior change and knowledge improvement, which is common for evaluations of health promotion programs. In the future, as more health apps are created, it is essential that apps that claim to have a public health objective undergo a rigorous evaluation of their acceptability, efficacy, and actual use. Indicators of outcomes beyond changes in behavior and knowledge should be reported; change in health status or access to care should also be reported. This systematic review has helped us note the characteristics associated with improved acceptability and efficacy, which can be helpful for the development of future apps.

An examination of socioeconomic and racial/ethnic disparities in the awareness, knowledge and utilization of three colorectal cancer screening modalities

While colorectal cancer (CRC) mortality rates have been decreasing, disparities by socioeconomic status (SES) and race/ethnicity persist. CRC screening rates remain suboptimal among low SES and racial/ethnic minority populations, despite the availability of multiple screening modalities. Understanding awareness, knowledge, and utilization of common screening modalities within different racial/ethnic and SES groups is critical to inform efforts to improve population screening uptake and reduce disparities in CRC-related health outcomes. Through the theoretical lenses of diffusion of innovation and fundamental cause theory, we examined the associations of race/ethnicity and SES with awareness, knowledge, and utilization of three guideline recommended CRC screening strategies among individuals at average risk for CRC. Data were obtained from a survey of a nationally representative panel of US adults conducted in November 2019. The survey was completed by 31.3% of invited panelists (1595 of 5097). Analyses were focused on individuals at average risk for CRC, aged 45–75 for awareness and knowledge outcomes (n = 1062) and aged 50–75 for utilization outcomes (n = 858). Analyses revealed racial/ethnic and SES disparities among the three CRC screening modalities, with more racial/ethnic and SES differences observed in the awareness, knowledge, and utilization of screening colonoscopy and mt-sDNA than FIT/gFOBT. Patterns of disparities are consistent with previous research showing that inequities in social and economic resources are associated with an imbalanced adoption of medical innovations. Our findings demonstrate a need to increase awareness, knowledge, and access of various CRC screening modalities in specific populations defined by race/ethnicity or SES indicators. Efforts to increase CRC screening should be tailored to the needs and social-cultural context of populations. Interventions addressing inequalities in social and economic resources are also needed to achieve more equitable adoption of CRC screening modalities and reduce disparities in CRC-related health outcomes.

•

Socioeconomic status linked to screening method awareness gap, notably mt-sDNA.

•

Screening modalities with low demand on patient resources more likely to be adopted.

•

Screening education needs to emphasize uniform starting age for all modalities.

•

Tailoring education to low resource communities may improve screening uptake.

The Intersections Between Social Determinants of Health, Health Literacy, and Health Disparities

This chapter synthesizes what is known about the relationship between social disadvantage and measures of low health literacy (LHL), and reviews the research examining whether LHL is an explanatory factor connecting social disadvantage, health outcomes, and health disparities. Written from a U.S. perspective, the chapter then offers a novel conceptual framework that presents how the social determinants of health might interact with LHL to result in health disparities. The framework articulates relationships that reflect public health pathways and healthcare pathways, which include their related health literacies. In addition, the chapter highlights as an exemplar one important potential causal mechanism in the healthcare pathway by exploring the communication model in outpatient care, as communication has been very well-studied with respect to both health disparities and HL. The chapter then, provides two examples of HL interventions aligned with the conceptual framework, one of which addresses the health care literacy pathway, and the other addresses the public health literacy pathway. The chapter continues with a number of cautionary statements based on the inherent limitations of current HL research, including problems and concerns specific to the attribution of HL as an explanatory factor for extant socioeconomic and racial/ethnic health disparities. The chapter closes with recommendations regarding future research directions.

Demographics Predict Stage III/IV Colorectal Cancer in Individuals Under Age 50

GOALS

The goal of this study was to quantify the association between demographic factors and advanced colorectal cancer (CRC) in patients under age 50.

BACKGROUND

CRC incidence in the United States has declined in older individuals but increased in those under age 50 (early-onset). More than 60% of early-onset CRC patients present with advanced disease (stage III/IV), but predictors of stage in this population are poorly defined.

STUDY

We analyzed CRC cases diagnosed between age 20 and 49 in the United States Surveillance, Epidemiology, and End Results (SEER) 18 database during 2004 to 2015. Logistic regression models were fit to assess the impact of age, sex, race, ethnicity, marital status, and cancer site on the probability of advanced disease.

RESULTS

The analysis included 37,044 cases. On multivariable regression, age was inversely associated with advanced disease. Relative to 45 to 49-year-olds, 40 to 44-year-olds had 8% greater odds of having advanced CRC, and 20 to 24-year-olds had 53% greater odds. Asians, blacks, and Pacific Islanders had 10%, 12%, and 45% greater odds of advanced disease compared with whites. Compared with nonpartnered individuals, those with partners had 11% lower odds of advanced CRC. Both right-sided and left-sided colon cancer were more likely to be diagnosed at stage IV compared with rectal cancer.

CONCLUSIONS

Among individuals with early-onset CRC, younger age, Asian, black, or Pacific Islander race, and being nonpartnered were predictors of advanced disease at presentation. Colon cancer was more likely to be diagnosed at stage IV than rectal cancer. Patient characteristics associated with advanced CRC may indicate both differences in tumor biology and disparities in health care access.

Health Literacy, Language, and Cancer-Related Needs in the First 6 Months After a Breast Cancer Diagnosis

PURPOSE

Low health literacy (HL) and language negatively affect cancer screening and prevention behaviors; less is known about how they affect the patient's experience during cancer treatment. This study explores associations among HL, spoken language, and dimensions of cancer-related needs within 6 months of receiving a breast cancer diagnosis.

METHODS

Women speaking English, Spanish, or Haitian Creole, enrolled in a patient navigation study at diagnosis, completed a survey in their primary spoken language at baseline and 6 months to characterize their cancer-related needs. HL was measured using the Brief Health Literacy Screening Tool. Outcomes included the Cancer Needs Distress Inventory (CaNDI; n = 38 items) and the Communication and Attitudinal Self-Efficacy scale (CASE-Cancer) for cancer (n = 12 items). Linear regressions measured the impact of HL and language on total CaNDI and CASE-Cancer scale for cancer scores and subscales, adjusted for demographics.

RESULTS

At baseline, 262 women participated and 228 (87%) followed up at 6 months. Of these, 38% had adequate HL, 33% had marginal HL, and 29% had inadequate HL. Women with inadequate or marginal HL had higher median baseline CaNDI scores (P = .02) and lower self-efficacy scores (P = .008), relative to those with adequate HL. Haitian-Creole speakers had significantly lower CANDI scores at baseline (P = .03). Adjusting for demographics, differences in CaNDI scores at baseline remained significant for those with lower HL and Haitian-Creole speakers. At 6 months, differences in self-efficacy persisted for Haitian-Creole speakers.

CONCLUSION

Findings suggest that interventions oriented to mitigating HL and language barriers might reduce distress at the time of diagnosis and improve self-efficacy over the course of treatment.

Association of Skin Cancer Risk and Protective Behaviors with Health Literacy Among Young Adults in the USA

BACKGROUND

The goal of this study was to investigate the association of health literacy with skin cancer risk and protective behaviors among young adults at moderate to high risk of skin cancer, the most common cancer.

METHOD

A US national sample of 958 adults, 18-25 years old, at moderate to high risk of developing skin cancer, completed a survey online. Behavioral outcomes were ultraviolet (UV) radiation exposure (e.g., indoor and outdoor tanning, sunburn) and protective (e.g., sunscreen use, sunless tanning) behaviors. Multivariable regression analyses were conducted to determine whether health literacy (a four-item self-report measure assessing health-related reading, understanding, and writing) was associated with behavioral outcomes while controlling for demographic factors.

RESULTS

Higher health literacy was independently associated with less sunbathing, odds ratio (OR) = 0.77, 95% confidence interval (CI) = 0.60-0.98; less indoor tanning, OR = 0.38, CI = 0.31-0.48; and less use of tanning oils, OR = 0.54, CI = 0.43-0.69. However, health literacy was also associated with a lower likelihood of wearing long pants, OR = 0.76, CI = 0.58-0.99, or a hat, OR = 0.68, CI = 0.53-0.87, when outdoors. On the other hand, higher health literacy was associated with higher incidental UV exposure, OR = 1.69, CI = 1.34-2.14, and a greater likelihood of ever having engaged in sunless tanning, OR = 1.50, CI = 1.17-1.92.

CONCLUSION

Interestingly, higher health literacy was associated with lower levels of intentional tanning yet also higher incidental UV exposure and lower skin protection among US young adults. These findings suggest that interventions may be needed for young adults at varying levels of health literacy as well as populations (e.g., outdoor workers, outdoor athletes/exercisers) who may be receiving large amounts of unprotected incidental UV.

Analyzing factors enabling colorectal cancer screening adherence in Korean Americans using the Andersen's Behavioral Model of Health Services Utilization

Purpose/objectives: Korean Americans (KAs) report suboptimal colorectal cancer (CRC) screening adherence. This study investigated factors that enable KAs to adhere to CRC screening guidelines using the Andersen's Behavioral Model of Health Services Utilization. Design: Cross-sectional survey using self-reported measures of CRC screening behaviors. Sample and methods: Purposive sampling was used to recruit 433 KAs aged 50-75 from the Atlanta metropolitan area who completed questionnaires measuring predisposing (i.e., gender, age, marital status, and educational attainment), enabling (income, health insurance, regular annual health checkups, doctor's recommendation English proficiency, CRC knowledge, self-efficacy for CRC screening, and decisional balance in CRC screening), and need (family cancer history and self-reported health status) factors associated with CRC screening. Findings: A multiple logistic regression model including all 14 predictor variables revealed that several enabling factors (i.e., income, regular annual health checkups, doctor's recommendation, self-efficacy, and decisional balance) independently predicted increased CRC screening adherence in KAs. No predisposing or need factors independently predicted CRC screening. Conclusions and implications for psychosocial providers or policy: To increase CRC screening adherence among KAs, psychosocial interventions should target on improving their self-efficacy and decisional balance regarding CRC screening, while policy interventions should focus on promoting health providers' CRC screening recommendations during routine health checkups.

Analyzing Factors of Breast Cancer Screening Adherence among Korean American Women Using Andersen's Behavioral Model of Healthcare Services Utilization

Objectives

Regular uptake of mammography screening reduces the risk of advanced stage diagnosis of breast cancer (BC). However, BC screening rates remain suboptimal among Korean American (KA) women. Using the Andersen's Behavioral Model of Healthcare Services Utilization, this study examined factors associated with mammography screening among KA women aged 50 to 80 years in the state of Georgia, USA.

Methods

We used purposive sampling to recruit study participants in the Atlanta metropolitan area from May 2015 to February 2016. A total of 303 KA women completed a cross-sectional, self-report survey about their sociodemographics, health care access information, knowledge, self-efficacy, decisional balance, and mammography history.

Results

Descriptive analyses confirmed low rates of mammography screening in the participants. Multiple logistic regression analyses showed that having a mammogram within the past year was associated with greater BC knowledge, higher scores of decisional balance and fewer annual health check-ups among KA women without any cancer history.

Conclusions

The findings offer implications for health policy aimed at increasing BC screening by leveraging enabling factors among medically underserved KA women at both structural and cultural levels.

Patient-Provider Language Concordance and Health Outcomes: A Systematic Review, Evidence Map, and Research Agenda

Although patient-provider language concordance has the potential to reduce health disparities for people with limited English proficiency, no previous work has synthesized this literature. Our systematic review sought to describe the characteristics of studies examining relationships between language concordance and health outcomes, summarize the nature of observed associations, and propose an evidence map and research agenda. A comprehensive search of published articles identified 38 quantitative studies for inclusion. Most studies were cross-sectional, conducted in primary care, concentrated in Western states, and focused on Spanish speakers and physician providers. Results were split between supporting a positive association versus no association of language concordance with patient behaviors, provider behaviors, interpersonal processes of care, and clinical outcomes. Several methodological limitations were identified. Based on these results, we developed an evidence map, identified knowledge gaps, and proposed a research agenda. There is a particular need for quasi-experimental longitudinal studies with well-characterized samples.

Factors Associated with Reported Colorectal Cancer Screening Among Lao-American Immigrants in Minnesota

Colorectal Cancer (CRC) is common in Lao Americans, but screening is suboptimal. To investigate CRC screening rates of Lao Americans in Minnesota, and how predisposing characteristics, enabling resources, and perceived need are associated with screening. We conducted a convenience-sample cross-sectional survey of 50-75-year-old Lao Americans, using step-wise multivariate logistic regression to identify factors associated with ever being screened. Of the 118 survey participants, 45% ever received CRC screening. In univariate regression, some enabling resources (having a primary care provider, higher self-efficacy in pursuing screening) and perceived needs (knowledge of who should be screened, higher number of chronic illnesses) were associated with screening. In multivariate logistic regression, the odds of ever being screened was 12.4 times higher for those with a primary care provider than for those without (p = 0.045). The findings reinforce a need for developing culturally tailored interventions focused on Lao-American immigrants to promote CRC screening.

Colorectal Cancer Screening Compliance among Asian and Pacific Islander Americans

Colorectal cancer (CRC) screening prevalence remains low among Asians and Pacific Islanders. This study examined disparities and predictors of CRC screening compliance in adults age 50-75 years in Asians and Pacific Islanders in Hawai'i. Hawai'i Behavioral Risk Factor Surveillance System (BRFSS) data for 2011-2014 were analyzed. CRC screening status was dichotomized. Logistic regression was used to examine ethnic differences in and predictors of CRC screening status. Filipinos (OR 0.56), Chinese (OR 0.70), and Hawaiians (OR 0.75) were significantly less likely than whites to be CRC compliant. Higher education and income, employment, regular health provider, and routine checkups were important predictors of CRC compliance. Findings confirm lower CRC screening compliance in three of the four largest Asian and Pacific Islander groups in Hawai'i and that CRC screening compliance is influenced by several factors. Culturally tailored education and navigation services may be effective in reducing these disparities.

Evidence of Differences and Discrimination in the Delivery of Care: Colorectal Screening in Healthy People and in the Care and Surveillance of Patients with Inflammatory Bowel Disease

Objectives: In this review the management of colorectal disease will be investigated as an exemplar of common practice in the UK in an attempt to identify factors responsible for the more general experiences of patients from ethnic minorities. Within this field such populations have a lower uptake of cancer screening programmes and their experience of day-to-day care for chronic gastrointestinal disorders is poor. Study design: PubMed and Google Scholar were reviewed in 2016 to identify publications concerning colorectal screening in patients with inflammatory bowel disease and healthy communities. Methods: Data were extracted from each paper and the references exploded to identify other potential reports. Results: It is reported that barriers exist both at individual and access levels but little has been done to overcome these. There have been a number of suggestions as to how to provide equitable access, but there is a clear need to ensure that these are evidence based and have been tested and shown to be effective in clinical trials. Conclusions: Clearly, current systems of surveillance and screening will only make a difference if they provide effective and acceptable services to all potential clients. Most programmes fail to address the specific risks and anxieties of minority groups, which are thought to be poorly compliant. This review considers those factors that may play a part and suggests approaches that could overcome these deficiencies. Some clues as to these factors may come from work with patients with chronic disorders.

Questionnaire Validation of Colorectal Cancer Literacy Scale among Thai People in Northeastern Thailand

Background: Colorectal cancer is an important public health problem worldwide. Although progress in screening and treatment has considerably improved the prognosis in the developed world, in developing countries colorectal cancer mortality rate remains relatively high. Colorectal cancer screening literacy is an important initial step in overcoming this problem. Development of a validated assessment instrument is therefore important for implementation of appropriate health education programs to facilitate early detection. Objectives: This study focused on generation and validation of a colorectal cancer screening literacy scale for Thai people in northeastern Thailand. Methods: This methodological study was carried out in two phases: (1) literature reviews and semi-structured interviews were used to select items, then the content and face validity were checked; and (2) a confirmatory factor analysis (CFA) was conducted to test construct validity and reliability. A self-administered questionnaire was used to collect data from Thai people aged 50- 65 in June 2017. Results: For the total of 400 participants who responded (response rate 100 %), the age ranged from 50 to 65 years old (mean = 57.3, SD = 4.616). The colorectal cancer screening literacy scale was designed to include 6 domains and it was shown to have good internal consistency, and CFA demonstrated the model to fit data adequately (Chi-squared/degree of freedom = 1.079, p = 0.061, CFI = 1.00, GFI = 0.93, AGFI = 0.91, RMSEA = 0.014 and SRMR = 0.036). The final version of its, consisting of 57 items across the 6 domains covering key aspects of colorectal cancer screening literacy, demonstrated good psychometric properties for this population. Conclusions: Use of the colorectal cancer screening literacy scale in Thai people could lead to improved educational programs for optimizing colorectal cancer screening.

Color-encoding visualizations as a tool to assist a nonliterate population in completing health survey responses

Visual representations of data have increasingly included color-encodings to help engage participants in health research. However, there is limited information on the way in which participants interpret color or on the influence of embedded cultural interpretations of color on survey responses. This study examines the interpretation of color-encodings used to indicate survey response options and their impact on participants' responses. Using a descriptive, cross-sectional design, interviews were conducted with 30 older Hmong adults from one Midwestern city in the United States. A survey data collection method was developed using: (a) an Audio-Computer-Assisted Self-Interviewing tool with (b) text-based and color-encoded response options and (c) assistance from a familiar helper. We analyzed the responses using directed content analysis. Findings reveal that some colors (red, black, and white) have strong cultural connotations; such colors were strongly correlated with specific emotions, while others (green, blue, purple, and pink) had no cultural meaning. Early in the survey, some older Hmong were distracted by response options indicated in red and black, influencing their response choices. However, with repeated instructions from the helpers, all participants overcame the color-related distractions and completed the survey. The findings highlight the importance of using colors cautiously and purposively in visualization development.

Analyzing Factors Associated With Decisional Stage of Adoption for Colorectal Cancer Screening Among Older Korean Americans Using Precaution Adoption Process Model

Introduction: For Korean Americans (KAs), colorectal cancer (CRC) screening rates remain lower than the national target. This study aimed to examine factors predicting decisional stage of CRC screening adoption among older KAs using the precaution adoption process model. Method: Convenience sampling was employed to recruit KAs aged 50 to 75 years from the Atlanta metropolitan area in the United States. A total of 433 KAs completed a cross-sectional survey that collects information on sociodemographics, CRC screening history, a physician's recommendation, knowledge, self-efficacy, and decisional balance pertaining CRC screening, and precaution adoption process model stage. Results: Higher scores of decisional balance (odds ratio [OR] = 1.34), having a physician's recommendation (OR = 8.61), and having regular annual medical checkups (OR = 4.44) were significantly associated with higher decisional stage compared with lower stage, controlling for other variables. Discussion: Intervention research should incorporate consideration of individuals' decisional stage to move KAs forward from not engaging the screening to maintaining regular participation in CRC screening.

Colorectal Cancer Screening Participation Among Asian Americans Overall and Subgroups in an Integrated Health Care Setting with Organized Screening

Background

Screening reduces colorectal cancer deaths, but <50% of Asian Americans are screening up-to-date according to surveys, with variability across Asian subgroups. We examined colorectal cancer screening participation among Asian Americans overall and Asian subgroups in a large integrated health care system with organized screening.

Methods

Data were electronically accessed to characterize screening in 2016 for Asians overall and subgroups relative to the National Colorectal Cancer Roundtable target of ≥80% screening and compared with non-Hispanic whites. Screening up-to-date was defined as a colonoscopy with 10 years, a sigmoidoscopy within 5 years, or a fecal immunochemical test (FIT) completed in 2016.

Results

Among 436,398 patients, 69,826 (16.0%) were Asian, of whom 79.8% were screening up-to-date vs. 77.6% of non-Hispanic whites (p < 0.001). Almost all subgroups met the 80% target: Chinese (83.3%), Vietnamese (82.4%), Korean (82.1%), other Asian (80.3%), Filipino (78.7%), Asian Indian (79.6%), and Japanese (79.0%). Among Asians overall and non-Hispanic whites, 50.6% and 48.4% of members were up-to-date with screening by colonoscopy, and 28.0% and 28.2% were up-to-date by FIT, respectively. Across Asian subgroups, colonoscopy most frequently accounting for being screening up-to-date (range: 47.4–59.7%), followed by FIT (range: 21.6–31.5%).

Conclusions

In an organized screening setting, there were minimal differences in screening participation among Asian subgroups and almost all met the 80% screening target, despite differences in language preference. Screening test type differences across subgroups suggest possible preferences in screening modality, which can inform future research into tailored education or outreach.

Insufficient evidence on health literacy amongst Indigenous people with cancer: a systematic literature review

Background

Indigenous people experience poorer cancer survival outcomes compared with non-Indigenous people. Currently, there is growing awareness of poor health literacy as a determinant of cancer outcomes. However, little attention has been given to researching cancer-related health literacy amongst Indigenous people.

Objectives

To systematically review empirical studies of cancer health literacy amongst Indigenous people worldwide.

Methods

Articles were identified in Medline (1946-2013); Pre-Medline; CINAHL; PsycINFO (1967-2013); PubMed; Current Contents/All Editions (1993-2013); Allied Health and Complimentary Medicine (1985-2013), and in the reference lists of retrieved articles and by expert consultation. 64 abstracts were screened for inclusion and 16 articles were retained.

Results

There is a paucity of high-quality research concerning of health literacy amongst Indigenous cancer patients. No articles used formal measures of health literacy and data on the prevalence of health literacy was not reported. Of the 7 articles describing interventions only one included a control group and the remainder employed quasi-experimental methods.

Conclusions

Research is needed to explore the cultural relevance of existing measures of health literacy and to document the prevalence of health literacy amongst Indigenous people with cancer. A better understanding of Indigenous cancer patients' health literacy is required before health literacy interventions can be designed to improve Indigenous cancer outcomes.

A Cross-Sectional Assessment of Literacy and Awareness, Attitudes, and Beliefs About Colorectal Cancer and Its Screening in Riyadh Region

This study aims to explore the association between functional health literacy and awareness for, beliefs, and attitudes of patients with colorectal cancer (CRC) and CRC screening test in Riyadh, Saudi Arabia. A total of 256 participants from two different tertiary level hospitals in Riyadh, Saudi Arabia were recruited in this study. The participants were interviewed by a trained researcher between October and December 2015. All respondents answered a three-part questionnaire which included demographic data, questions related to CRC awareness, attitude, behaviour, and short Test of Functional Health Literacy in Adults (STOFHLA). More than half of the participants had an inadequate awareness of functional health literacy skills (FHLS), 16.4 % had marginal of FHLS awareness and 17.6 % had adequate awareness about FHLS as assessed by the STOFHLA. Overall, the majority of the participants in both marginal and adequate aware groups showed a limited awareness about colorectal cancer screening and testing. A significant association was found on awareness of the patients about frequencies that they should have been tested for colorectal cancer and functional health literacy. No significant association was found between functional health literacy as assessed by STOFHLA and concerns of Faecal Occult Blood Test (FOBT) (p = 0.384) and sigmoidoscopy or colonoscopy might cause embarrassment (p = 0.089), harm (p = 0.917), and pain (p = 0.849). The present study revealed a low level of health literacy among Saudi adults in Riyadh region. Although the level of literacy was low, the bigger concern is that of the poor awareness and beliefs of Saudi adults about CRC and CRC screening.

Racial/ethnic disparities among Asian Americans in inpatient acute myocardial infarction mortality in the United States

Background

Acute myocardial infarction (AMI) is a common high-risk disease with inpatient mortality of 5% nationally. But little is known about this outcome among Asian Americans (Asians), a fast growing racial/ethnic minority in the country. The objectives of the study are to obtain near-national estimates of differences in AMI inpatient mortality between minorities (including Asians) and non-Hispanic Whites and identify comorbidities and sociodemographic characteristics associated with these differences.

Method

This is a retrospective analysis of 2010–2011 state inpatient discharge data from 10 states with the largest share of Asian population. We identified hospitalization with a primary diagnosis of AMI using the ICD-9 code and used self-reported race/ethnicity to identify White, Black, Hispanic, and Asian. We performed descriptive analysis of sociodemographic characteristics, medical comorbidities, type of AMI, and receipt of cardiac procedures. Next, we examined overall inpatient AMI mortality rate based on patients’ race/ethnicity. We also examined the types of AMI and a receipt of invasive cardiac procedures by race/ethnicity. Lastly, we used sequential multivariate logistic regression models to study inpatient mortality for each minority group compared to Whites, adjusting for covariates.

Results

Over 70% of the national Asian population resides in the 10 states. There were 496,472 hospitalizations with a primary diagnosis of AMI; 75% of all cases were Whites, 10% were Blacks, 12% were Hispanics, and 3% were Asians. Asians had a higher prevalence of cardiac comorbidities, including hypertension, diabetes, and kidney failure compared to Whites (p-value< 0.01). There were 158,623 STEMI (ST-elevation AMI), and the proportion of hospitalizations for STEMI was the highest for Asians (35.2% for Asians, 32.7% for Whites, 25.3% for Blacks, and 32.1% for Hispanics). Asians had the highest rates of inpatient AMI mortality: 7.2% for Asians, 6.3% for Whites, 5.4% for Blacks, and 5.9% for Hispanics (ANOVA p-value < 0.01). In adjusted analyses, Asians (OR = 1.11 [95% CI: 1.04–1.19]) and Hispanics (OR = 1.14 [1.09–1.19]) had a higher likelihood of inpatient mortality compared to Whites.

Conclusions

Asians had a higher risk-adjusted likelihood of inpatient AMI mortality compared to Whites. Further research is needed to identify the underlying reasons for this finding to improve AMI disparities for Asians.

Unraveling the Determinants to Colorectal Cancer Screening Among Asian Americans: a Systematic Literature Review

Colorectal cancer (CRC) is one of the top three cancers experienced among Asian American (AA) men and women. One effective way to decrease incidence and mortality from CRC is the adherence of regular CRC screening; however, AA continue to receive the lowest screening rates compared to other racial/ethnic groups. When disaggregating this heterogeneous population, further disparities exist between subgroups. Examination of facilitators and barriers to cancer screening among AA subgroups is fairly recent and the synthesis of this information is limited. As such, a systematic review was conducted examining the facilitators and the barriers among Chinese, Filipino, Korean, and Japanese Americans using a systematic literature review method. The Health Belief Model served as the primary theoretical framework for this study and used to organize and synthesize the facilitators and barriers to CRC screening. In total, 22 articles yielded 29 examinations of each of the AA subgroups. Different facilitators and barriers to screening uptake for each subgroup were revealed; however, consistent across all the subgroups was physician recommendation as a facilitator and participants' unawareness of screening tests and those stating having no problems/symptoms of CRC as a barrier across screening modalities. Tailored approach in outreach and intervention efforts are suggested when achieving to improve CRC screening in AA ethnic subgroups.

Predictors of Colorectal Cancer Knowledge and Screening Among Asian Americans Aged 50-75 years old

Colorectal cancer, the second leading cause of mortality in the USA, can be prevented with colorectal cancer screening. However, many people who should receive the screening do not get screened. To learn more, this study estimated the prevalence of up-to-date colorectal cancer (CRC) screening and examined the relationship between CRC knowledge and screening compliance among Asian Americans living in the Baltimore-Washington Metropolitan area. The study included a cross-sectional sample of 274 Chinese, Korean, and Vietnamese Americans aged 50-75 years old. Participants completed a questionnaire regarding CRC knowledge in either their preferred native language or in English, and data were collected in person. The percentage of total participants with up-to-date overall CRC screening was 52.9%. Up-to-date fecal occult blood test (FOBT) screening was 15.0% and colonoscopy was 50.7%. The average CRC knowledge score was 6.10 out of 9 (SD = 2.91). Those with high education, high English proficiency, married, health insurance, and good physical health ratings had higher CRC knowledge. In multivariate analysis, CRC knowledge was significantly correlated with increasing up-to-date colonoscopy (aOR = 2.74, 1.13-6.64). Having health insurance (aOR = 4.40, 2.33-8.32) was another predictor of up-to-date colonoscopy. These findings suggest that CRC knowledge is a strong predictor of CRC screening behavior in Asian American populations. Lack of CRC screening knowledge still remains an important barrier to screening, and increased public awareness is necessary to achieve greater screening compliance.

Does acculturation narrow the health literacy gap between immigrants and non-immigrants-An explorative study

OBJECTIVES

To compare functional health literacy (HL) levels in three immigrant groups to those of the German- and Italian-speaking non-immigrant population in Switzerland. Moreover, to investigate whether language-independent, respectively language-dependent, functional HL and variables of acculturation were associated with self-reported health status among immigrants.

METHODS

Language-independent HL was assessed with the Short Test of Functional Health Literacy (S-TOFHLA) in the respective native languages. Language-dependent HL was measured using Brief Health Literacy Screeners (BHLS) asking about participants' confidence in understanding medical information in the language of the host country. Measures of acculturation included length of stay and age when taking residency in Switzerland.

RESULTS

In particular Albanian- and Portuguese-speaking immigrants had lower levels of functional HL. In unadjusted analysis "age when taking residency in Switzerland" was associated with the BHLS. Adjusted analysis showed that the BHLS were significantly associated with self-reported health among all immigrant groups (p≤0.01).

CONCLUSIONS

Functional HL that is dependent on understanding of medical information in the language of the new host country is a better predictor for self-reported health status among immigrants than language-independent HL.

PRACTICE IMPLICATIONS

In the clinical setting limited functional HL might be a significant obstacle to successful disease treatment and prevention in immigrants.

Mental Illness Is Not Associated with Adherence to Colorectal Cancer Screening: Results from the California Health Interview Survey

BACKGROUND

Colorectal cancer is the second leading cause of cancer-specific death in the USA. Evidence suggests people with mental illness are less likely to receive preventive health services, including cancer screening. We hypothesized that mental illness is a risk factor for non-adherence to colorectal cancer-screening guidelines.

METHODS

We analyzed results of the 2007 California Health Interview Survey to test whether mental illness is a risk factor for non-adherence to colorectal cancer-screening recommendations among individuals age 50 or older (N = 15,535). This cross-sectional dataset is representative of California. Screening was defined as either fecal occult blood testing during the preceding year, sigmoidoscopy, or colonoscopy during the preceding 5 years. Mental illness was identified using the Kessler K6 screening tool. Associations were evaluated using weighted multivariate logistic regressions.

RESULTS

Mental illness was not associated with colorectal cancer-screening adherence (OR 0.89; 95% CI 0.63-1.25). Risk factors for non-adherence included being female (OR 1.25; 95% CI 1.09-1.44), delaying accessing health care during the previous year (OR 1.89; 95% CI 1.56-2.29).

CONCLUSION

Unlike previous studies, this study did not find a relationship between mental illness and colorectal cancer-screening adherence. This could be due to differences in study populations. State-specific healthcare policies involving care coordination for individuals with mental illness could also influence colorectal cancer-screening adherence in California.

Determinants of cancer screening in Asian-Americans

PURPOSE

Recent data suggest that Asian-Americans (AsAs) are more likely to present with advanced disease when diagnosed with cancer. We sought to determine whether AsAs are under-utilizing recommended cancer screening.

METHODS

Cross-sectional analysis of the 2012 Behavioral Risk Factor Surveillance System comprising of AsAs and non-Hispanic White (NHW) community-dwelling individuals (English and Spanish speaking) eligible for colorectal, breast, cervical, or prostate cancer screening according to the United States Preventive Services Task Force recommendations. Age, education and income level, residence location, marital status, health insurance, regular access to healthcare provider, and screening were extracted. Complex samples logistic regression models quantified the effect of race on odds of undergoing appropriate screening. Data were analyzed in 2015.

RESULTS

Weighted samples of 63.3, 33.3, 47.9, and 30.3 million individuals eligible for colorectal, breast, cervical, and prostate cancer screening identified, respectively. In general, AsAs were more educated, more often married, had higher levels of income, and lived in urban/suburban residencies as compared to NHWs (all p < 0.05). In multivariable analyses, AsAs had lower odds of undergoing colorectal (odds ratio [OR] 0.78, 95 % confidence interval [CI] 0.63-0.96), cervical (OR 0.45, 95 % CI 0.36-0.55), and prostate cancer (OR 0.55, 95 % CI 0.39-0.78) screening and similar odds of undergoing breast cancer (OR 1.29, 95 % CI 0.92-1.82) screening as compared to NHWs.

CONCLUSIONS

AsAs are less likely to undergo appropriate screening for colorectal, cervical, and prostate cancer. Contributing reasons include limitations in healthcare access, differing cultural beliefs on cancer screening and treatment, and potential physician biases. Interventions such as increasing healthcare access and literacy may improve screening rates.

Are cancer-related decision aids appropriate for socially disadvantaged patients? A systematic review of US randomized controlled trials

BACKGROUND

Shared decision-making (SDM) is considered a key component of high quality cancer care and may be supported by patient decision aids (PtDAs). Many patients, however, face multiple social disadvantages that may influence their ability to fully participate in SDM or to use PtDAs; additionally, these social disadvantages are among the determinants of health associated with greater cancer risk, unwarranted variations in care and worse outcomes. The purpose of this systematic review is to describe the extent to which disadvantaged social groups in the United States (US) have been included in trials of cancer-related PtDAs and to highlight strategies, lessons learned and future opportunities for developing and evaluating PtDAs that are appropriate for disadvantaged populations.

METHODS

We selected cancer-related US studies from the Cochrane 2014 review of PtDAs and added RCTs meeting Cochrane criteria from searches of PubMed, CINAHL, PsycINFO (January 2010 to December 2013); and reference lists. Two reviewers independently screened titles/abstracts; three reviewers independently screened full text articles, performed data extraction and assessed: 1) inclusion of participants based on seven indicators of social disadvantage (limited education; female gender; uninsured or Medicaid status; non-U.S. nativity; non-White race or Hispanic ethnicity; limited English proficiency; low-literacy), and 2) attention to social disadvantage in the development or evaluation of PtDAs.

RESULTS

Twenty-three of 39 eligible RCTs included participants from at least one disadvantaged subgroup, most frequently racial/ethnic minorities or individuals with limited education and/or low-literacy. Seventeen studies discussed strategies and lessons learned in attending to the needs of disadvantaged social groups in PtDA development; 14 studies targeted disadvantaged groups or addressed subgroup differences in PtDA evaluation.

CONCLUSIONS

The diversity of the US population is represented in a majority of cancer-related PtDA RCTs, but fewer studies have tailored PtDAs to address the multiple social disadvantages that may impact patients' participation in SDM. More detailed attention to the comprehensive range of social factors that determine cancer risk, variations in care and outcomes is needed in the development and evaluation of PtDAs for disadvantaged populations.

The Relationship between Health Literacy and Health Disparities: A Systematic Review

OBJECTIVES

Health literacy is commonly associated with many of the antecedents of health disparities. Yet the precise nature of the relationship between health literacy and disparities remains unclear. A systematic review was conducted to better understand in how far the relationship between health literacy and health disparities has been systematically studied and which potential relationships and pathways have been identified.

METHODS

Five databases, including PubMed/MEDLINE and CINAHL, were searched for peer-reviewed studies. Publications were included in the review when they (1) included a valid measure of health literacy, (2) explicitly conceived a health disparity as related to a social disparity, such as race/ethnicity or education and (3) when results were presented by comparing two or more groups afflicted by a social disparity investigating the effect of health literacy on health outcomes. Two reviewers evaluated each study for inclusion and abstracted relevant information. Findings were ordered according to the disparities identified and the role of health literacy in explaining them.

RESULTS

36 studies were included in the final synthesis. Most of the studies investigated racial/ethnic disparities, followed by some few studies that systematically investigated educational disparities. Some evidence was found on the mediating function of health literacy on self-rated health status across racial/ethnic and educational disparities, as well as on the potential effect of health literacy and numeracy on reducing racial/ethnic disparities in medication adherence and understanding of medication intake.

CONCLUSION

Overall the evidence on the relationship between health literacy and disparities is still mixed and fairly limited. Studies largely varied with regard to health(-related) outcomes under investigation and the health literacy assessments used. Further, many studies lacked a specific description of the nature of the disparity that was explored and a clear account of possible pathways tested.

Health literacy and meeting breast and cervical cancer screening guidelines among Asians and whites in California

Objectives

Empirical evidence regarding cancer screening and health literacy is mixed. Cancer is the leading cause of death in Asian Americans, yet screening rates are notably low. Using a population-based sample, we determined if health literacy: (1) was associated with breast and cervical cancer screening, and (2) helped to explain Asian cancer screening disparities.

Methods

We analyzed the 2007 California Health Interview Survey for Asian (Japanese, Chinese, Filipino, Korean, Vietnamese, other Asian) and white women within age groups relevant to US Preventive Services Task Force (USPSTF) screening guidelines: cervical: ages 21–65 (n = 15,210) and breast: ages 50–74 (n = 11,163). Multilevel logistic regression models predicted meeting USPSTF screening guidelines both with and without self-reported health literacy controlling for individual-level and contextual-level factors.

Results

Low health literacy significantly (p < 0.05) predicted lower cancer screening in final models for both cancer types. In unadjusted models, Asians were significantly less likely than whites to receive both screening types and significantly more likely to report low health literacy. However, in multivariable models, the addition of the low health literacy variable did not diminish Asian vs. white cancer screening disparities.

Conclusions

Self-reported health literacy predicted cervical and breast cancer screening, but was not able to explain Asian cancer screening disparities. We provide new evidence to support a relationship between health literacy and cancer screening. Health literacy is likely a useful focus for interventions to improve cancer screening and ultimately reduce the burden of cancer. To specifically reduce Asian cancer disparities, additional areas of focus should be considered.
