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

Promoting Health Literacy in the Workplace Among Civil Servants: Cross-Sectional Study

Background

In 2022, the World Health Organization highlighted the alarming state of oral health (OH) worldwide and urged action to include OH in initiatives on noncommunicable diseases. The population needs improved OH skills and attitudes and an adequate level of OH literacy (OHL) and general health literacy (HL). The implementation of health promotion actions in the workplace, which is a part of most people's lives, appears to be an opportunity. In France, civil servants have several socioprofessional levels and represent an excellent model with results transposable to the population.

Objective

This study aimed at determining the OHL and HL level of civil servants in France in order to implement specific prevention actions in their workplaces.

Methods

A cross-sectional study of French civil servants was conducted in France from October 2023 to February 2024. Participants completed three validated questionnaires in French: (1) a questionnaire on OH knowledge, (2) the Oral Health Literacy Instrument, French version (OHLI-F; this is composed of reading comprehension and numeracy sections) to assess the OHL level, and (3) the Short Test of Functional Health Literacy in Adults, French version (s-TOFHLA-F) to assess the HL level. The scores for OH knowledge, the OHLI-F, and the s-TOFHLA-F were reported as means (SD) and the 95% CI. These scores were classified into 3 categories: adequate (75-100), marginal (60-74) and inadequate (0-59). ANOVA and binary logistic regression were performed. The OHLI-F reading comprehension and OHLI-F numeracy scores were compared using the Welch 2-sample t test and a paired t test (both 2-tailed). For the correlation matrix, the Pearson correlation and related tests were computed.

Results

A total of 1917 persons completed the 3 questionnaires, with adequate levels of OHL (n=1610, 84%), OH knowledge (n=1736, 90.6%), and HL (n=1915, 99.9%). The scores on the s-TOFHLA-F (mean 98.2, SD 2.8) were higher than the OHLI-F (mean 80.9, SD 7.9) and OH knowledge (mean 87.6, SD 10.5). The OHLI-F was highly correlated with OH knowledge (P<.001), but the OHLI-F and OH knowledge had a low correlation with s-TOFHLA-F (P=.43). The OHLI-F reading comprehension score was significantly higher than the OHLI-F numeracy score (P<.001). Age, education level, and professional category impacted the 3 scores (P<.001). The professional category was a determinant of adequate OHLI-F and OH knowledge scores.

Conclusions

Some French civil servants had inadequate or marginal levels of OH knowledge (n=181, 9.5%) and OHL (n=307, 16%) but none had an inadequate level of HL. Results highlighted the relevance of implementing OH promotion programs in the workplace. They should be nonstandardized, adapted to the literacy level of professional categories of workers, and focused on numeracy skills. Thus, appropriate preventive communication and improved literacy levels are the means to achieve greater disease equity and combat the burden of noncommunicable diseases.

Empirical analysis of health-related behaviors among older Hakka adults: a latent class analysis

Background

Little is known about health-related behaviors of the older Hakka population in China. We aimed to explore the characteristics and correlates of health-related behaviors among older Hakka adults.

Methods

We used data from the China's Health-Related Quality of Life Survey for Older Adults 2018. Latent class analysis (LCA) defined latent classes of health-related behaviors for 1,262 older Hakka adults aged 60 and above. Generalized linear regression and multinomial logistic regression analysis were used to identify factors influencing the number and the latent classes of health-related behaviors, respectively.

Results

The LCA showed that the latent classes could be stratified as the risk group (14.82%), healthy group (55.71%), and inactive group (29.48%). Sex, age, years of education, current residence, living arrangement, average annual household income, and currently employed were associated with the number of healthy behaviors. Compared with the participants in the healthy group, widowed/others (OR = 5.85, 95% CI = 3.27, 10.48), had 15,001-30,000 (OR = 2.05, 95% CI = 1.21, 3.47) and 60,001 or higher (OR = 3.78, 95% CI = 1.26, 11.36) average annual household income, and currently employed (OR = 3.40, 95% CI = 1.99, 5.81) were highly associated with risk group. Additionally, the participants who are widowed/others (OR = 4.30, 95% CI = 2.70, 6.85) and currently employed (OR = 1.95, 95% CI = 1.27, 2.98) were highly associated with the inactive group.

Conclusion

This study identified factors specifically associated with older Hakka adults' health-related behaviors from an LCA perspective. The findings indicate that policymakers should give more attention to older adults living alone and implement practical interventions to promote health-related behaviors among them.

Racial Composition of Social Environments Over the Life Course Using the Pictorial Racial Composition Measure: Development and Validation Study

BACKGROUND

Studies investigating the impact of racial segregation on health have reported mixed findings and tended to focus on the racial composition of neighborhoods. These studies use varying racial composition measures, such as census data or investigator-adapted questions, which are currently limited to assessing one dimension of neighborhood racial composition.

OBJECTIVE

This study aims to develop and validate a novel racial segregation measure, the Pictorial Racial Composition Measure (PRCM).

METHODS

The PRCM is a 10-item questionnaire of pictures representing social environments across adolescence and adulthood: neighborhoods and blocks (adolescent and current), schools and classrooms (junior high and high school), workplace, and place of worship. Cognitive interviews (n=13) and surveys (N=549) were administered to medically underserved patients at a primary care clinic at the Barnes-Jewish Hospital. Development of the PRCM occurred across pilot and main phases. For each social environment and survey phase (pilot and main), we computed positive versus negative pairwise comparisons: mostly Black versus all other categories, half Black versus all other categories, and mostly White versus all other categories. We calculated the following validity metrics for each pairwise comparison: sensitivity, specificity, correct classification rate, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, false positive rate, and false negative rate.

RESULTS

For each social environment, the mostly Black and mostly White dichotomizations generated better validity metrics relative to the half Black dichotomization. Across all 10 social environments in the pilot and main phases, mostly Black and mostly White dichotomizations exhibited a moderate-to-high sensitivity, specificity, correct classification rate, positive predictive value, and negative predictive value. The positive likelihood ratio values were >1, and the negative likelihood ratio values were close to 0. The false positive and negative rates were low to moderate.

CONCLUSIONS

These findings support that using either the mostly Black versus other categories or the mostly White versus other categories dichotomizations may provide accurate and reliable measures of racial composition across the 10 social environments. The PRCM can serve as a uniform measure across disciplines, capture multiple social environments over the life course, and be administered during one study visit. The PRCM also provides an added window into understanding how structural racism has impacted minoritized communities and may inform equitable intervention and prevention efforts to improve lives.

Racial Composition of Past and Current Social Environments and Health Literacy

BACKGROUND

Research is needed to understand the impact of social determinants of health on health literacy throughout the life course. This study examined how racial composition of multiple past and current social environments was related to adults' health literacy.

METHODS

In this study, 546 adult patients at a primary care clinic in St. Louis, Missouri, completed a self-administered written questionnaire that assessed demographic characteristics and a verbally administered component that assessed health literacy with the Rapid Estimate of Adult Literacy in Medicine - Revised (REALM-R) and Newest Vital Sign (NVS), and self-reported racial composition of six past and four current social environments. Multilevel logistic regression models were built to examine the relationships between racial composition of past and current social environments and health literacy.

RESULTS

Most participants identified as Black or multiracial (61%), had a high school diploma or less (54%), and household income <$20,000 (72%). About 56% had adequate health literacy based on REALM-R and 38% based on NVS. In regression models, participants with multiple past white environments (e.g., locations/conditions in which most of the people who live, go to school, work, and have leisure time are White) and (vs. 0 or 1) were more likely to have adequate health literacy based on REALM-R (adjusted odds ratio [aOR] = 1.79; 95% confidence interval [CI]: 1.04-3.07). Similarly, participants who had multiple past white social environments were more likely (aOR = 1.94, 95% CI: 1.15-3.27) to have adequate health literacy based on NVS than those who had not. The racial composition of current social environments was not significantly associated with health literacy in either model.

CONCLUSIONS

Racial composition of past, but not current, educational and residential social environments was significantly associated with adult health literacy. The results highlight the importance of examining the impact of social determinants over the life course on health literacy. The findings suggest that policies ensuring equitable access to educational resources in school and community contexts is critical to improving equitable health literacy.

Feasibility of a 2-Part Substance Use Screener Self-Administered by Patients on Paper: Observational Study

BACKGROUND

Measurement-based care in behavioral health uses patient-reported outcome measures (PROMs) to screen for mental health symptoms and substance use and to assess symptom change over time. While PROMs are increasingly being integrated into electronic health record systems and administered electronically, paper-based PROMs continue to be used. It is unclear if it is feasible to administer a PROM on paper when the PROM was initially developed for electronic administration.

OBJECTIVE

This study aimed to examine the feasibility of patient self-administration of a 2-part substance use screener-the Tobacco, Alcohol, Prescription medications, and other Substances (TAPS)-on paper. This screener was originally developed for electronic administration. It begins with a limited number of questions and branches to either skip or reflex to additional questions based on an individual's responses. In this study, the TAPS was adapted for paper use due to barriers to electronic administration within an urgent care behavioral health clinic at an urban health safety net hospital.

METHODS

From August 2021 to March 2022, research staff collected deidentified paper TAPS responses and tracked TAPS completion rates and adherence to questionnaire instructions. A retrospective chart review was subsequently conducted to obtain demographic information for the patients who presented to the clinic between August 2021 and March 2022. Since the initial information collected from TAPS responses was deidentified, demographic information was not linked to the individual TAPS screeners that were tracked by research staff.

RESULTS

A total of 507 new patients were seen in the clinic with a mean age of 38.7 (SD 16.6) years. In all, 258 (50.9%) patients were male. They were predominantly Black (n=212, 41.8%), White (n=152, 30%), and non-Hispanic or non-Latino (n=403, 79.5%). Most of the patients were publicly insured (n=411, 81.1%). Among these 507 patients, 313 (61.7%) completed the TAPS screener. Of these 313 patients, 76 (24.3%) adhered to the instructions and 237 (75.7%) did not follow the instructions correctly. Of the 237 respondents who did not follow the instructions correctly, 166 (70%) answered more questions and 71 (30%) answered fewer questions than required in TAPS part 2. Among the 237 patients who did not adhere to questionnaire instructions, 44 (18.6%) responded in a way that contradicted their response in part 1 of the screener and ultimately affected their overall TAPS score.

CONCLUSIONS

It was challenging for patients to adhere to questionnaire instructions when completing a substance use screener on paper that was originally developed for electronic use. When selecting PROMs for measurement-based care, it is important to consider the structure of the questionnaire and how the PROM will be administered to determine if additional support for PROM self-administration needs to be implemented.

The low health literacy in Latin America and the Caribbean: a systematic review and meta-analysis

BACKGROUND

Health literacy (HL) impacts people's health and well-being. In Latin America and the Caribbean (LAC), there are no general estimates of the prevalence of low HL. This study aimed to estimate the prevalence of low HL among citizens of LAC and identify the tools used to measure it.

METHODS

We included observational studies quantifying the prevalence of low HL in people living in LAC. We searched PubMed, CINAHL, EMBASE, ERIC, LILACS, PsycINFO, Redalyc, SciELO, Web of Science, PQDT, and the reference lists of the included studies in June 2023. Two reviewers independently conducted the selection, extraction, and risk of bias assessment using the JBI Critical Appraisal Tools. Meta-analysis of proportions using random effects models was used to summarize the prevalence of low HL estimated. This prevalence was measured in each study using different classification methods: word recognition items, reading and numeracy comprehension items, and self-reported comprehension items.

RESULTS

Eighty four studies involving 23,914 participants from 15 countries were included. We identified 23 tools to assess HL, and most of the studies were carried out in health services. The pooled prevalence of low HL were 44.02% (95%CI: 36.12-52.24) for reading and numeracy comprehension items, 50.62% (95%CI: 41.82-59.39) for word recognition items, and 41.73% (95%CI: 31.76-52.43) for self-reported comprehension items.

CONCLUSION

Despite the variability in the prevalence of low HL and a diversity of tools, the average of low HL is of concern. Almost half of the participants in the included studies have low HL. Most of the studies targeted users of healthcare services. Further research investigating the prevalence of low HL in the general population and actions focused on health education, communication, and information are necessary.

Improving health and scientific literacy in disadvantaged groups: A scoping review of interventions

OBJECTIVE

To explore approaches for developing and implementing interventions aimed at improving health literacy and health-related scientific literacy in disadvantaged groups.

METHODS

A scoping review of literature published in 2012-2022 was conducted, followed by quality appraisal of eligible studies.

RESULTS

Interventions were conducted mainly in community settings, where the most popular venues were adult education facilities. The primary target groups were those with limited income or education, ethnic minorities, or immigrants. Programs were often held in-person using interactive and culturally appropriate methods. They were predominantly focused on functional and interactive health literacy dimensions rather than on critical and scientific ones. Evaluations measured knowledge, health literacy, behavioral and psychological outcomes using various quantitative and qualitative instruments.

CONCLUSIONS

The findings offer a comprehensive overview of the ways to design and evaluate health and scientific literacy interventions tailored to disadvantaged groups.

PRACTICE IMPLICATIONS

Future interventions should prioritize participatory designs, culturally appropriate materials, and shift focus to critical and scientific health literacy, as well as to program scalability in less controlled conditions.

Does health literacy mediate the relationship between socioeconomic status and health related outcomes in the Belgian adult population?

BACKGROUND

Health literacy (HL) has been put forward as a potential mediator through which socioeconomic status (SES) affects health. This study explores whether HL mediates the relation between SES and a selection of health or health-related outcomes.

METHODS

Data from the participants of the Belgian health interview survey 2018 aged 18 years or older were individually linked with data from the Belgian compulsory health insurance (n = 8080). HL was assessed with the HLS-EU-Q6. Mediation analyses were performed with health behaviour (physical activity, diet, alcohol and tobacco consumption), health status (perceived health status, mental health status), use of medicine (purchase of antibiotics), and use of preventive care (preventive dental care, influenza vaccination, breast cancer screening) as dependent outcome variables, educational attainment and income as independent variables of interest, age and sex as potential confounders and HL as mediating variable.

RESULTS

The study showed that unhealthy behaviours (except alcohol consumption), poorer health status, higher use of medicine and lower use of preventive care (except flu vaccination) were associated with low SES (i.e., low education and low income) and with insufficient HL. HL partially mediated the relationship between education and health behaviour, perceived health status and mental health status, accounting for 3.8-16.0% of the total effect. HL also constituted a pathway by which income influences health behaviour, perceived health status, mental health status and preventive dental care, with the mediation effects accounting for 2.1-10.8% of the total effect.

CONCLUSIONS

Although the influence of HL in the pathway is limited, our findings suggest that strategies for improving various health-related outcomes among low SES groups should include initiatives to enhance HL in these population groups. Further research is needed to confirm our results and to better explore the mediating effects of HL.

Assessment of health literacy in a French emergency department

BACKGROUND

Health literacy (HL) has become a subject of major interest in public health worldwide. It is known to be linked to self-efficacy in care use and to global health status, and a non-negligible frequency of problematic or inadequate levels of HL in populations worldwide is reported. As this has yet to be evaluated in France, the present study aimed to evaluate the HL level of patients in a French emergency department (ED).

METHODS

We conducted a descriptive, cross-sectional observational, single center study in the ED of the Lyon Sud hospital (Hospices civils de Lyon, Lyon, France). The primary endpoint was the HL level of the patients determined according to the score obtained using the 16-item European Health Literacy Survey Questionnaire. The secondary endpoint was the identification of sociodemographic factors associated with the HL level.

RESULTS

A total of 189 patients were included for analysis. 10% (95% CI [3%; 17%]) of the patients had an inadequate HL, 38% (95% CI [31%; 45%]) had a problematic HL, and 53% (95% CI [46%; 61%] had an adequate HL. In multivariate analysis, age and perceived health status were independent predictors of the HL level; OR =0.82 (95% CI [0.69; 0.97]; p=0.026) for a 10-year increase in age, and OR =1.84 (95% CI [1.22; 2.82]; p=0.004]).

CONCLUSIONS

The HL level of the patients in the ED studied herein was similar to that found in the population of France and other European countries and was influenced by age and perceived health status, which are both associated with care needs. It may be therefore interesting to explore in future studies how taking into consideration HL in the general population may lead to a better self-efficacy in care and optimize the use of the healthcare system.

Arts Engagement as a Health Behavior: An Opportunity to Address Mental Health Inequities

The significance of mental health inequities globally is illustrated by higher rates of anxiety and depression amongst racial and ethnic minority populations as well as individuals of lower socioeconomic status. The COVID-19 pandemic has further exacerbated these pre-existing mental health inequities. With rising mental health concerns, arts engagement offers an accessible, equitable opportunity to combat mental health inequities and impact upstream determinants of health. As the field of public health continues to shift its focus toward social ecological strategies, the social ecological model of health offers an approach that prioritizes social and structural determinants of health. To capture the impacts of arts engagement, this paper creates an applied social ecological model of health while aiming to advocate that engaging in the arts is a protective and rehabilitative behavior for mental health.

Readability analysis and concept mapping of PROMs used for headache disorders

OBJECTIVE

To assess the readability and the comprehensiveness of patient-reported outcome measures (PROMs) utilized in primary headache disorders literature.

BACKGROUND

As the health-care landscape has evolved toward a patient-centric model, numerous PROMs have been developed to capture treatment outcomes in patients with headache disorders. For these PROMs to advance our understanding of headache disorders and their treatment impact, they must be easy to understand (i.e., reading grade level 6 or less) and comprehensively capture what matters to patients with headache. The aim of this study was to (a) assess the readability of PROMs utilized in headache disorders literature, and (b) assess the comprehensiveness of PROMs by mapping their content to a health-related quality of life framework.

METHODS

In this scoping review, recently published systematic reviews were used to identify PROMs used in primary headache disorders literature. Readability analysis was performed at the level of individual items and full PROM using established readability metrics. The content of the PROMs was mapped against a health-related quality-of-life framework by two independent reviewers.

RESULTS

In total, 22 PROMs (15 headache disorders related, 7 generic) were included. The median reading grade level varied between 7.1 (interquartile range [IQR] 6.3-7.8) and 12.7 (IQR 11.8-13.2). None of the PROMs were below the recommended reading grade level for patient-facing material (grade 6). Three PROMs, the Migraine-Treatment Assessment Questionnaire, the Eurolight, and the European Quality of Life 5 Dimensions 3 Level Version, were between reading grade levels 7 and 8; the remaining 19 PROMs were above reading grade level 8. In total, the PROMs included 425 items. Most items (n = 134, 32%) assessed physical function (e.g., work, activities of daily living). The remaining items assessed physical symptoms (n = 127, 30%; e.g., pain, nausea), treatment effects on symptoms (n = 65, 15%; e.g., accompanying symptoms relief, headache relief), treatment impact (n = 56, 13%; e.g., function, side effects), psychological well-being (n = 41, 10%; e.g., anger, frustration), social well-being (n = 29, 7%; e.g., missing out on social activities, relationships), psychological impact (n = 14, 3%; e.g., feeling [not] in control, feeling like a burden), and sexual well-being (n = 3, 1%; e.g., sexual activity, sexual interest). Some of the items pertained to treatment (n = 27, 6%), of which most were about treatment type and use (n = 12, 3%; e.g., medication, botulinum toxin), treatment access (n = 10, 2%; e.g., health-care utilization, cost of medication), and treatment experience (n = 9, 2%; e.g., treatment satisfaction, confidence in treatment).

CONCLUSION

The PROMs used in studies of headache disorders may be challenging for some patients to understand, leading to inaccurate or missing data. Furthermore, no available PROM comprehensively measures the health-related quality-of-life impact of headache disorders or their treatment, resulting in a limited understanding of patient-reported outcomes. The development of an easy-to-understand, comprehensive, and validated headache disorders-specific PROM is warranted.

Characterizing Health Literacy and Its Correlates Among Individuals With Traumatic Brain Injury (TBI): A TBI Model Systems Study

OBJECTIVE

To characterize health literacy among individuals with traumatic brain injury (TBI) at least a year postinjury and to explore its relationship to sociodemographic variables, injury severity, and cognition.

SETTING

Community following discharge from inpatient rehabilitation.

PARTICIPANTS

In total, 205 individuals with complicated mild to severe TBI who completed follow-up as part of a national longitudinal study of TBI and completed a web-based health literacy measure.

DESIGN

Multicenter, cross-sectional, observational study.

MAIN MEASURES

Health Literacy Assessment Using Talking Touchscreen Technology.

RESULTS

Thirty-one percent of the sample demonstrated marginal/inadequate health literacy; 69% demonstrated adequate health literacy. A higher proportion of non-Hispanic White adults had adequate health literacy than non-Hispanic Black and Hispanic adults. Individuals with greater than a high school education were more likely to have adequate health literacy than those with a high school education or less. Better executive functioning performance was related to adequate health literacy. Better episodic memory performance was related to adequate health literacy, but only for those with complicated mild to moderate injury.

CONCLUSIONS

A substantial proportion of individuals with TBI have marginal/inadequate health literacy, which may impact their understanding, appreciation, and use of health-related information and recommendations. While low health literacy may be preexisting, directly related to TBI, or a combination of both, it should be screened and considered by professionals when communicating with persons with TBI. Healthcare providers should tailor their communication approaches and presentation of health information, particularly for those with low health literacy.

Relative predictive value of sociodemographic factors for chronic diseases among All of Us participants: a descriptive analysis

BACKGROUND

Although sociodemographic characteristics are associated with health disparities, the relative predictive value of different social and demographic factors remains largely unknown. This study aimed to describe the sociodemographic characteristics of All of Us participants and evaluate the predictive value of each factor for chronic diseases associated with high morbidity and mortality.

METHODS

We performed a cross-sectional analysis using de-identified survey data from the All of Us Research Program, which has collected social, demographic, and health information from adults living in the United States since May 2018. Sociodemographic data included self-reported age, sex, gender, sexual orientation, race/ethnicity, income, education, health insurance, primary care provider (PCP) status, and health literacy scores. We analyzed the self-reported prevalence of hypertension, coronary artery disease, any cancer, skin cancer, lung disease, diabetes, obesity, and chronic kidney disease. Finally, we assessed the relative importance of each sociodemographic factor for predicting each chronic disease using the adequacy index for each predictor from logistic regression.

RESULTS

Among the 372,050 participants in this analysis, the median age was 53 years, 59.8% reported female sex, and the most common racial/ethnic categories were White (54.0%), Black (19.9%), and Hispanic/Latino (16.7%). Participants who identified as Asian, Middle Eastern/North African, and White were the most likely to report annual incomes greater than $200,000, advanced degrees, and employer or union insurance, while participants who identified as Black, Hispanic, and Native Hawaiian/Pacific Islander were the most likely to report annual incomes less than $10,000, less than a high school education, and Medicaid insurance. We found that age was most predictive of hypertension, coronary artery disease, any cancer, skin cancer, diabetes, obesity, and chronic kidney disease. Insurance type was most predictive of lung disease. Notably, no two health conditions had the same order of importance for sociodemographic factors.

CONCLUSIONS

Age was the best predictor for the assessed chronic diseases, but the relative predictive value of income, education, health insurance, PCP status, race/ethnicity, and sexual orientation was highly variable across health conditions. Identifying the sociodemographic groups with the largest disparities in a specific disease can guide future interventions to promote health equity.

Factors affecting hesitancy toward COVID-19 vaccine booster doses in Canada: a cross-national survey

OBJECTIVE

COVID-19 transmission, emergence of variants of concern, and weakened immunity have led to recommended vaccine booster doses for COVID-19. Vaccine hesitancy challenges broad immunization coverage. We deployed a cross-national survey to investigate knowledge, beliefs, and behaviours toward continued COVID-19 vaccination.

METHODS

We administered a national, cross-sectional online survey among adults in Canada between March 16 and March 26, 2022. We utilized descriptive statistics to summarize our sample, and tested for demographic differences, perceptions of vaccine effectiveness, recommended doses, and trust in decisions, using the Rao-Scott correction for weighted chi-squared tests. Multivariable logistic regression was adjusted for relevant covariates to identify sociodemographic factors and beliefs associated with vaccine hesitancy.

RESULTS

We collected 2202 completed questionnaires. Lower education status (high school: odds ratio (OR) 1.90, 95% confidence interval (CI) 1.29, 2.81) and having children (OR 1.89, CI 1.39, 2.57) were associated with increased odds of experiencing hesitancy toward a booster dose, while higher income ($100,000-$149,999: OR 0.60, CI 0.39, 0.91; $150,000 or more: OR 0.49, CI 0.29, 0.82) was associated with decreased odds. Disbelief in vaccine effectiveness (against infection: OR 3.69, CI 1.98, 6.90; serious illness: OR 3.15, CI 1.69, 5.86), disagreeing with government decision-making (somewhat disagree: OR 2.70, CI 1.38, 5.29; strongly disagree: OR 4.62, CI 2.20, 9.7), and beliefs in over-vaccinating (OR 2.07, CI 1.53, 2.80) were found associated with booster dose hesitancy.

CONCLUSION

COVID-19 vaccine hesitancy may develop or increase regarding subsequent vaccines. Our findings indicate factors to consider when targeting vaccine-hesitant populations.

Introduction to the Special Issue: International Responses to Prevention Intervention Research During Human Ecosystem Disruptions

For decades, human ecosystem disruptions (HEDs), including pandemics, natural disasters, and socio-economic crises, have shaped national and international responses affecting everyday life. These disruptions present challenges and opportunities for prevention science to address emerging behavioral and mental health research questions, intervention strategies, methodologies, analyses, and research collaboration. This paper introduces a special issue that aims to document examples of how prevention science research teams had (1) globally improved health and well-being through swift, scientifically based responses during HED events and (2) advanced our understanding of the conduct and outcomes of prevention intervention research during crises such as pandemics, natural disasters, and socio-economic crises. The issue presents six research studies conducted in over ten different countries (e.g., Australia, Mexico, China). This issue includes original empirical and descriptive work that addressed HED implications for preventive interventions at within-country and cross-national levels. The findings hold potential applications for responses during current and future pandemics and natural disasters. Participants reflected on methodological and contextual considerations during HEDs, such as navigating travel restrictions, adapting ongoing research efforts to accommodate scientific learning during disruptions, and assessing the impact of policies redistributing preventive resources during and after a HED.

Supporting health education policies: translation, cross-cultural adaptation and validation of a health literacy instrument, in French

Background

Oral health is a fundamental human right and is inseparable and indivisible from overall health and well-being. Oral Health Literacy (OHL) has been proved to be fundamental to promoting oral health and reducing oral health inequalities. To our knowledge, no OHL instrument to evaluate OHL level is currently validated in French language despite the fact it is the fifth most widely spoken languages on the planet. The Oral health literacy Instrument (OHLI) appears to be the most interesting OHL instrument to adapt into French because it is already available in English, Spanish, Russian, Malaysian, and it contains both reading comprehension and numeracy sections. Its psychometric properties have been rated as adequate.

Objective

The aim of this study was to translate and adapt cross-culturally the OHLI into French, to evaluate its psychometric properties and to compare its results to oral health knowledge.

Method

This study followed and applied well-established processes of translation, cross-cultural adaptation and validation, based on the recommendations of the World Health Organization guidelines and on the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) study design checklist for patient-reported outcomes. Two psychometric assessments were planned, the comparison of OHLI-F scores according to education level and frequency of dental visits, and the test-retest reliability of the OHLI-F.

Results

A total of 284 participants answered the OHLI-F. The OHLI-F scores were significantly different between participants with different levels of education and frequency of dental visits (p < 0.001). Participants with an education level lower than the baccalaureate, and those who never visit the dentist or only in case of pain, had significantly lower OHLI-F scores. Internal consistency was excellent (Cronbach's alpha = 0.881-0.914). Test-retest reliability was very high (intraclass correlation = 0.985 to 0.996).

Conclusion

The OHLI-F has demonstrated adequate psychometric properties and can therefore be used to measure oral health literacy in French-speaking populations.

Evaluating health claim assessment skills of parents with preschool children: A cross-sectional study using Informed Health Choices Claim Evaluation Tool

Background

Health literacy is a global problem and is particularly relevant when making health care decisions about small children. We analysed how parents of preschool children assess health claims and explored the predictors of their assessment skill.

Methods

We conducted a survey with questions from the Claim Evaluation Tools (CET) database, part of the Informed Health Choices (IHC) project, in ten paediatric primary care practices of the Split-Dalmatia County Health Center, Split, Croatia, from 1 February to 31 March 2023. Eligible participants were parents accompanying preschool-aged children for check-ups. We also collected data on parents' and children's demographic and health characteristics (including the presence of any chronic illness in the child), visits to paediatric emergency service, hospitalisations, vaccination status, the presence of chronic illness of parents or relatives, and whether parents had to made treatment decisions for themselves and/or their family member.

Results

Overall, 402 parents of preschool children (median age 35 years (interquartile range (IQR) = 31.0-38.3)) had a median IHC CET test score of 10.0 (IQR = 8.0-11.0) out of 12 questions. The multiple regression analysis showed that female gender, higher level of education, being employed, and having a history of a visit to paediatric emergency service were significant predictors of the test score, explaining 21.9% of the variance.

Conclusions

Parents of preschool children have a very good ability for critical assessment of health-related statements in a complex health care system and an environment of generally unsatisfactory health literacy. Further studies should explore how parents understand health claims in different geographical, socio-economic and cultural setting, and explore educational interventions to increase critical thinking abilities and informed decision-making, especially among fathers, unemployed parents and those with lower levels of education.

Trusted Sources of Information and COVID-19 Vaccine Uptake in a Sample of Latinx Sexual and Gender Minorities in South Florida

OBJECTIVE

To examine factors associated with COVID-19 vaccine uptake in a sample of Latino/a/x sexual and/or gender minority (SGM) individuals in South Florida.

DESIGN

Data were collected via an online survey from March 2021 to August 2022, as part of the Community Engagement Alliance Against COVID-19 Disparities. A multivariate regression analysis was fit using completion of a COVID-19 vaccine regimen as the outcome. Key covariates included trusted sources of information (eg, doctor, media), COVID-19-related challenges (eg, accessing medication, transportation), and dominant wave of SARS-CoV-2 at the time of data collection.

SETTING

Miami-Dade and Broward counties, Florida.

RESULTS

White Latino/a/x, bachelor's educated respondents, and those with high levels of trust in community organizations had significantly greater odds of vaccination.

CONCLUSION

Community organizations may be key to improving vaccine uptake among marginalized Latino/a/x SGM for COVID-19 and other emerging communicable diseases, such as meningitis and Mpox (monkeypox). The results of this study suggest that tailored public health messaging and additional funding for vaccine distribution are needed to better equip community organizations with the resources they need to serve this population.

Are Mobile Applications in Laryngology Designed for All Patients?

OBJECTIVES

Mobile applications (apps) are multiplying in laryngology, with little standardization of content, functionality, or accessibility. The purpose of this study is to evaluate the quality, functionality, health literacy, readability, accessibility, and inclusivity of laryngology mobile applications.

METHODS

Of the 3230 apps identified from the Apple and Google Play stores, 28 patient-facing apps met inclusion criteria. Apps were evaluated using validated scales assessing quality and functionality: the Mobile App Rating Scale (MARS) and the Institute for Healthcare Informatics App Functionality Scale. The Clear Communication Index (CDC) Institute of Medicine Strategies for Creating Health Literate Mobile Applications, and Patient Education Materials Assessment Tool (PEMAT) were used to evaluate apps health literacy level. Readability was assessed using established readability formulas. Apps were evaluated for language, accessibility features, and representation of a diverse population.

RESULTS

Twenty-six apps (92%) had adequate quality (MARS score > 3). The mean PEMAT score was 89% for actionability and 86% for understandability. On average, apps utilized 25/33 health literate strategies. Twenty-two apps (79%) did not pass the CDC index threshold of 90% for health literacy. Twenty-four app descriptions (86%) were above an 8th grade reading level. Only 4 apps (14%) showed diverse representation, 3 (11%) had non-English language functions, and 2 (7%) offered subtitles. Inter-rater reliability for MARS was adequate (CA-ICC = 0.715).

CONCLUSION

While most apps scored well in quality and functionality, many laryngology apps did not meet standards for health literacy. Most apps were written at a reading level above the national average, lacked accessibility features, and did not represent diverse populations. Laryngoscope, 133:1540-1549, 2023.

The Death Literacy Index: translation, cultural adaptation, and validation of the Chinese version

Objective

Applying public health approaches to address palliative care allows for a broader perspective. The Death Literacy Index (DLI) is a novel instrument designed to assess the knowledge and skills required to access, comprehend, and make informed decisions regarding end-of-life care. Translation of the DLI could strengthen the capacity to build desirable services and policies regarding dying and death. It could also help to identify the barriers to services and future advocacy efforts.

Methods

The DLI was forward translated into Chinese and backward translated through two panels. Two rounds of cognitive interviews and a pilot test were conducted before the survey. A sample of 3,221 participants was recruited via an online survey in five cities in southern China (Guangzhou, Zhuhai, Jiangmen, Hong Kong and Macao) to evaluate the factor structure, validity and reliability of the translated DLI. Additionally, multi-group confirmatory factor analyses (MGCFA) were performed to examine measurement invariance across genders and the experiences of parental death.

Results

Exploratory factor analysis showed a six-factor structure for the translated DLI, and confirmatory factor analysis confirmed the structure. The overall scale and subscales had high internal consistency and satisfactory validity. The results from MGCFA showed that death literacy was adequately invariant for different genders and experiences of parental death.

Conclusion

The Chinese DLI is a reliable and valid instrument for measuring death literacy among people in southern China, and therefore can be used for both research and community practice.

Community Health Worker-led Implementation of the Stanford Youth Diabetes Coaching Program in Underserved Latinx Communities

BACKGROUND

The Stanford Youth Diabetes Coaching Program (SYDCP) is an evidence-based program led by health care professionals to teach healthy youth who then coach family members with diabetes or other chronic conditions. This purpose of this study is to evaluate a Community Health Worker (CHW)-led implementation of the SYDCP for low-income Latinx students from underserved agricultural communities.

METHOD

CHWs were trained and virtually led 10 training sessions virtually during the COVID-19 for Latinx students who were recruited from high schools in agricultural regions of Washington state. Feasibility measures include recruitment, retention, class attendance, and successful coaching of a family member or friend. Acceptability was measured by responses on the post-training survey. Effectiveness was evaluated by pre-post changes in measures used in prior studies of the SYDCP such as level of activation and diabetes knowledge.

RESULTS

Thirty-four students were recruited, 28 completed the training and 23 returned both pre- and post-surveys. Over 80% of students attended 7 or more classes. All met with a family or friend and 74% met with them weekly. Approximately 80% of the students rated the program's usefulness as "very good" or "excellent." Pre-post increases in diabetes knowledge, nutrition-related behaviors, resilience, and activation were significant and similar to those observed in prior published studies of the SYDCP.

CONCLUSIONS

Findings support the feasibility, acceptability, and effectiveness of a CHW-led implementation of the SYDCP in underserved Latinx communities using a virtual remote model.

Your Tweets Matter: How Social Media Sentiments Associate with COVID-19 Vaccination Rates in the US

Objective

The aims of the study were to examine the association between social media sentiments surrounding COVID-19 vaccination and the effects on vaccination rates in the United States (US), as well as other contributing factors to the COVID-19 vaccine hesitancy.

Method

The dataset used in this study consists of vaccine-related English tweets collected in real-time from January 4 - May 11, 2021, posted within the US, as well as health literacy (HL), social vulnerability index (SVI), and vaccination rates at the state level.

Results

The findings presented in this study demonstrate a significant correlation between the sentiments of the tweets and the vaccination rate in the US. The results also suggest a significant negative association between HL and SVI and that the state demographics correlate with both HL and SVI.

Discussion

Social media activity provides insights into public opinion about vaccinations and helps determine the required public health interventions to increase the vaccination rate in the US.

Conclusion

Health literacy, social vulnerability index and monitoring of social media sentiments need to be considered in public health interventions as part of vaccination campaigns.

Health Literacy, Equity, and Communication in the COVID-19 Era of Misinformation: Emergence of Health Information Professionals in Infodemic Management

The health information management (HIM) field’s contribution to health care delivery is invaluable in a pandemic context where the need for accurate diagnoses will hasten responsive, evidence-based decision-making. The COVID-19 pandemic offers a unique opportunity to transform the practice of HIM and bring more awareness to the role that frontline workers play behind the scenes in safeguarding reliable, comprehensive, accurate, and timely health information. This transformation will support future research, utilization management, public health surveillance, and forecasting and enable key stakeholders to plan and ensure equitable health care resource allocation, especially for the most vulnerable populations. In this paper, we juxtapose critical health literacy, public policy, and HIM perspectives to understand the COVID-19 infodemic and new opportunities for HIM in infodemic management.

Precision communication: Physicians' linguistic adaptation to patients' health literacy

Little quantitative research has explored which clinician skills and behaviors facilitate communication. Mutual understanding is especially challenging when patients have limited health literacy (HL). Two strategies hypothesized to improve communication include matching the complexity of language to patients’ HL (“universal tailoring”); or always using simple language (“universal precautions”). Through computational linguistic analysis of 237,126 email exchanges between dyads of 1094 physicians and 4331 English-speaking patients, we assessed matching (concordance/discordance) between physicians’ linguistic complexity and patients’ HL, and classified physicians’ communication strategies. Among low HL patients, discordance was associated with poor understanding (P = 0.046). Physicians’ “universal tailoring” strategy was associated with better understanding for all patients (P = 0.01), while “universal precautions” was not. There was an interaction between concordance and communication strategy (P = 0.021): The combination of dyadic concordance and “universal tailoring” eliminated HL-related disparities. Physicians’ ability to adapt communication to match their patients’ HL promotes shared understanding and equity. The ‘Precision Medicine’ construct should be expanded to include the domain of ‘Precision Communication.’

Influence of Gender, Age and Field of Study on Hand Hygiene in Young Adults: A Cross-Sectional Study in the COVID-19 Pandemic Context

The effectiveness of hand hygiene (HH) on reducing the transmission of contagious diseases is widely known, although its use has been commonly associated with the area of healthcare. During the COVID-19 pandemic, HH was one of the main measures established to contain the transmission of this virus. The identification of the main barriers and facilitators of HH in young adults (aged 18-29 years old) will contribute to the better planning of HH training and its posterior success. A total of 716 young adults participated in the study by completing the ad hoc online questionnaire (#YesWeHand), which analyzed, among other aspects, the age range, gender and field of study that they belonged to. From the total participants, 81.3% indicated knowing how to perform HH correctly, while 49.4% affirmed having received training. The main reason for performing HH was concern for their own safety and that of others (75.8%), while forgetfulness (36.5%) was the main reason for not performing HH. In the group of young adults, being female, aged between 22 and 25 years old, and having studied in the area of Health Sciences, had a positive influence on correct HH. It is deemed necessary to maintain HH beyond the primary education stages, and to adapt it to different fields of education, ages, and genders, in order to maximize its success. Given the overrepresentation of participants from the healthcare field, it would be desirable to conduct more studies to ensure a better representation of the different educational levels and fields of study of the participants, in order to identify, in a more reliable way, the variables that influence HH.
