Cardiovascular disease risk and secondary prevention of cardiovascular disease among patients with low health literacy

Changes in disease-related knowledge and educational needs of patients with coronary heart disease over a six-month period between hospital discharge and follow-up

OBJECTIVE

To describe changes in the disease-related knowledge and educational needs of individuals with coronary heart disease (CHD).

METHODS

Patients hospitalized for CHD answered questionnaires about disease-related knowledge (Coronary Artery Disease Education Questionnaire-short version (CADE-Q-SV), score 0-20), educational needs (investigator-designed questions), health literacy (Short version of the European Health Literacy Survey Questionnaire (HLS-EU-Q16)), self-care (Self-Care of Coronary Heart Disease Inventory version (SC-CHDI)), and physical activity (Leisure-time Physical Activity Questionnaire) at discharge (T1) and six months later (T2).

RESULTS

Participants' (N = 308; mean [M] age=65.5 years [SD=8.7]; 81.5% male) knowledge scores increased from M= 13.8 (SD=3.2) to M= 14.8 (SD=2.8) (p < 0.001). At T1, educational level, age, health literacy, smoking, and self-care maintenance explained 14.5% of knowledge variability. At T2, these variables plus lack of awareness of CHD diagnosis explained 20.3% of the variability. Substantial educational needs were reported at both time points, although 89% received predischarge education.

CONCLUSION

The patients' educational needs were unfulfilled despite an increase in disease-related knowledge over time. Improved evidence-based patient education and follow-ups that address diagnosis, treatment, and self-care are needed.

PRACTICE IMPLICATIONS

Healthcare professionals can improve care of patients with CHD by providing focused patient education, prioritizing "need-to-know" topics and considering patients' health literacy.

Heart Disease Knowledge and Awareness in African American and Hispanic Women

OBJECTIVES

Coronary heart disease (CHD) is the leading cause of morbidity and mortality among US women. Minority women have higher rates of CHD and are more likely to experience adverse outcomes. Because of racial disparities in CHD outcomes, the purpose of this study was to assess CHD knowledge and awareness in African American and Hispanic women.

METHODS

Using a survey research design, a convenience sample of African American and Hispanic women was surveyed in their local communities. CHD knowledge, awareness, and demographic data were collected using an online survey. The survey was administered in English and Spanish using an iPad. CHD knowledge was assessed using a 7-item survey based on the American Heart Association's Life's Simple 7 brochure. CHD awareness was assessed using a 7-item survey adapted from the American Heart Association's Survey of Women's Cardiovascular Disease Awareness. CHD knowledge was scored on a scale of 0 to 7, and awareness was assessed based on responses to each question. The data analysis consisted of cross-tabulations and multivariable repeated measures analysis. We assessed differences in CHD knowledge and awareness based on race/ethnicity. We hypothesized that there would be statistically significant differences in CHD knowledge and awareness based on specific demographic factors (eg, age, income, education, health literacy).

RESULTS

A total of 100 African American (n=50) and Hispanic (n = 50) women participated in the study. Results revealed that CHD knowledge and awareness were limited for both groups. Seventy-three percent of participants (African American 66%; Hispanic 80%) did not know that CHD is the leading cause of death in women and 75% (African American 60%; Hispanic 90%) were moderately or not at all informed about CHD.

CONCLUSIONS

These findings support the need for more research on innovative strategies to improve CHD knowledge and awareness, particularly in African American and Hispanic women who are at highest risk, thereby addressing racial/ethnic and gender disparities in CHD morbidity and mortality.

Comparison of Newest Vital Sign and Brief Health Literacy Screen scores in a large, urban Hispanic cohort

OBJECTIVE

Prior studies comparing subjective and objective health literacy measures have yielded inconsistent results. Our aim was to examine the concordance between Newest Vital Sign (NVS) and Brief Health Literacy Screen (BHLS) scores in a large cohort of English- and Spanish-speaking urban Hispanic adults.

METHODS

Item means, standard deviations, corrected-item total correlations, Cronbach's alpha, and Spearman correlations and area under receiver operating characteristic (AUROC) curve analysis were used to compare NVS and BHLS items and total scores.

RESULTS

N = 2988 (n = 1259 English; n = 1729 Spanish). Scores on both measures demonstrated good internal consistency (NVS: α = .843 English, .846 Spanish; BHLS: α = .797 English, .846 Spanish) but NVS items had high difficulty; more than half of respondents scored 0. Measures were only weakly correlated (rs = .21, p < .001, English; rs = .19, p < .001, Spanish). The AUROC curves were .606 (English) and .605 (Spanish) for discriminating the lowest NVS scoring category.

CONCLUSION

Subjective health literacy scores were poor predictors of objective scores. Objective scores demonstrated floor effects, precluding discrimination at low levels of the trait continuum.

PRACTICE IMPLICATIONS

Subjective health literacy scores may fail to identify individuals with limited health literacy.

How to optimize the adherence to a guideline-directed medical therapy in the secondary prevention of cardiovascular diseases: a clinical consensus statement from the European Association of Preventive Cardiology

A key factor to successful secondary prevention of cardiovascular disease (CVD) is optimal patient adherence to treatment. However, unsatisfactory rates of adherence to treatment for CVD risk factors and CVD have been observed consistently over the last few decades. Hence, achieving optimal adherence to lifestyle measures and guideline-directed medical therapy in secondary prevention and rehabilitation is a great challenge to many healthcare professionals. Therefore, in this European Association of Preventive Cardiology clinical consensus document, a modern reappraisal of the adherence to optimal treatment is provided, together with simple, practical, and feasible suggestions to achieve this goal in the clinical setting, focusing on evidence-based concepts.

Engaging Female Community Health Volunteers (FCHVs) for cardiovascular diseases risk screening in Nepal

Introduction

Non-Communicable Diseases (NCDs) have become the leading public health problems worldwide and the cardiovascular diseases (CVDs) is one of the major NCDs. Female Community Health Volunteers (FCHVs) in Nepal are the key drivers to implementing frontline health services. We explored the potential for engaging FCHVs for CVD risk screening at the community level in Nepal.

Methods

We used multiple approaches (quantitative and qualitative) for data collection. The trained FCHVs administered CVD risk screening questionnaire among 491 adults in rural and urban areas and calculated the CVD risk scores. To maintain consistency and quality, a registered medical doctor also, using the same risk scoring chart, independently calculated the CVD risk scores. Kappa statistics and concordance coefficient were used to compare these two sets of risk screening results. Sensitivity and specificity analyses were conducted. Two focus group discussions among the FCHVs were conducted to determine their experiences with CVD risk screening and willingness to engage with CVD prevention and control efforts.

Results

The mean level of agreement between two sets of risk screening results was 94.5% (Kappa = 0.77, P<0.05). Sensitivity of FCHV screening was 90.3% (95% CI: 0.801–0.964); and the specificity was 97% (95% CI: 0.948, 0.984). FCHVs who participated in the FGDs expressed a strong enthusiasm and readiness to using the CVD risk screening tools. Despite their busy workload, all FCHVs showed high level of motivation and willingness in using CVD risk screening tools and contribute to the prevention and control efforts of NCDs. The FCHVs recommended needs for providing additional training and capacity building opportunities.

Conclusion

We conclude that there is a potential for engaging FCHVs to use simple CVD risk screening tools at the community level. The findings are promising, however, further studies engaging larger number of FCHVs and larger population would warrant feasibility of such tools within the existing healthcare systems in Nepal.

Assessment of electrocardiogram abnormality and associated factors among apparently healthy adult type 2 diabetic patients on follow-up at Jimma Medical Center, Southwest Ethiopia: Cross-sectional study

Background

Diabetes mellitus is a group of metabolic disorders causing long-term damage to the cardiovascular system which remains asymptomatic among diabetic patients. An electrocardiograph is a simple and first-line tool in the screening of cardiovascular diseases.

Objective

To assess electrocardiogram abnormality and associated factors among apparently healthy adult type 2 diabetes patients on follow-up at Jimma Medical Center, 2019.

Materials and methods

Institutional based cross-sectional study was conducted from April 1 to May 30, 2019, at Jimma Medical Center among selected type 2 diabetes patients. Systematic random sampling was employed to select the study participants. The World Health Organization stepwise approach and interviewer-administered semi-structured questionnaires were employed to collect basic data. Resting Electrocardiography was done using a standard 12-lead electrocardiograph machine. The collected data were checked for completeness, coded, entered into the Epi-data Version 4.0.2. and exported to SPSS Version 21. Descriptive statistics like frequencies, percentages, mean and standard deviations were carried out. Binary and multiple logistic regression was done and a p value of less than 0.05 was used as a level of significance.

Results

A total of 344 type 2 diabetes patients were interviewed and underwent electrocardiography making a 100% response rate. Electrocardiographic abnormality was identified among 209 (61%) of the respondents. Not attending formal education [AOR = 3.07, 95%, CI = 1.37–6.87], solid oil use, [AOR = 1.79, 95%, CI = 1.07–2.98], body mass index ≥ 25 kg/m² [AOR = 2.74, 95%, CI = 1.67–4.50] and long duration of diabetes ≥ 10 years [AOR = 3.36, 95%, CI = 1.46–7.71] were associated with electrocardiogram abnormality.

Conclusions

and recommendation

In this study, the majority (3/5th) of the participant had electrocardiogram abnormality. Not attending formal education, longer duration of diabetes ≥ 10 years, solid oil use, and increased body mass index ≥ 25 kg/m² were independent predictors of electrocardiographic abnormality. Integrating electrocardiogram screening in routine diabetic management can pick cardiac complications of diabetes.

Health Literacy Among Patients With Chronic Lung Disease Entering Pulmonary Rehabilitation and Their Resident Loved Ones

PURPOSE

The objective of this study was determine the prevalence of low health literacy (HL) and low reading ability among patients with chronic lung disease referred for pulmonary rehabilitation (PR) in the Netherlands and their loved ones; and to understand whether low HL or low reading ability influence PR outcomes.

METHODS

Health literacy was measured using the Health Literacy Survey-Europe Q16 (HLS-EU-Q16). Reading ability and cognitive functioning were measured using the Rapid Estimate of Adult Literacy in Medicine-Dutch (REALM-D) and the Montreal Cognitive Assessment. Exercise capacity, health status, and symptoms of anxiety and depression were assessed.

RESULTS

Patients (n = 120) entering PR and loved ones (n = 41) participated. Of all patients, 51% had low HL and 29% had low reading ability. Also, 39% of all loved ones had low HL. PR outcomes were comparable between patients with low or adequate HL. Patients with adequate reading ability showed greater improvement in symptoms of depression than patients with low reading ability (P = .047).

CONCLUSION

Low HL and low reading ability are common among patients entering PR and their loved ones. For patients with low or adequate HL, PR is an effective treatment. Whether considering low HL and low reading ability by offering tailored education during treatment could augment the benefits of PR warrants further study.

What is the Prevalence of Low Health Literacy in European Union Member States? A Systematic Review and Meta-analysis

BACKGROUND

Many studies have shown that low health literacy (HL) is associated with several adverse outcomes. In this study, we systematically reviewed the prevalence of low HL in Europe.

METHODS

PubMed, Embase, and Scopus were searched. Cross-sectional studies conducted in the European Union (EU), published from 2000, investigating the prevalence of low HL in adults using a reliable tool, were included. Quality was assessed with the Newcastle-Ottawa Scale. Inverse-variance random effects methods were used to produce pooled prevalence estimates. A meta-regression analysis was performed to assess the association between low HL and the characteristics of the studies.

RESULTS

The pooled prevalence of low HL ranged from of 27% (95% CI: 18-38%) to 48% (95% CI: 41-55%), depending on the literacy assessment method applied. Southern, Western, and Eastern EU countries had lower HL compared to northern Europe (β: 0.87, 95% CI: 0.40-1.35; β: 0.59, 95% CI: 0.25-0.93; and β: 0.72, 95% CI: 0.06-1.37, respectively). The assessment method significantly influenced the pooled estimate: compared to word recognition items, using self-reported comprehensions items (β: 0.61, 95% CI: 0.15-1.08), reading or numeracy comprehensions items (β: 0.77, 95% CI: 0.24-1.31), or a mixed method (β: 0.66, 95% CI: 0.01-1.33) found higher rates of low HL. Refugees had the lowest HL (β: 1.59, 95% CI: 0.26-2.92). Finally, lower quality studies reported higher rates of low HL (β: 0.56, 95% CI: 0.06-1.07).

DISCUSSION

We found that low HL is a public health challenge throughout Europe, where one in every three to almost one in every two Europeans may not be able to understand essential health-related material. Additional research is needed to investigate the underlying causes and to develop remedies.

Cardiovascular Diseases Health Literacy among Patients, Health Professionals, and Community-Based Stakeholders in a Predominantly Medically Underserved Rural Environment

OBJECTIVE

The central Appalachian region of the United States is disproportionately burdened with cardiovascular disease (CVD); however, the level of literacy about CVD among residents has not been well studied. This study aimed to examine the prevalence and factors of CVD health literacy (HL) among a sample of patients/caregivers, providers/professionals, and community stakeholders.

METHODS

In 2018, data were collected from central Appalachian residents in six states: Kentucky, North Carolina, Ohio, Tennessee, Virginia, and West Virginia. CVD HL status was determined by assessing correct responses to five interrelated questions about basic knowledge of CVD. Multiple logistic regression analyses were used to examine the associations between potential factors and CVD HL status.

RESULTS

Of the total respondents (N = 82), <50% correctly answered all 5 CVD HL questions. Multiple logistic regression analyses showed that compared with respondents with advanced college degrees, those with a college degree or less were more likely to have low HL for "typical symptom of CVD," "physical exercise and CVD," "blood pressure and CVD," and "stress and CVD." In addition, compared with respondents younger than 50 years, those 50 years and older were 3.79 times more likely to have low HL for "physical exercise and CVD."

CONCLUSIONS

These results suggest the incorporation of CVD HL into CVD care and that educational attainments should be part of CVD policies and programs in the region.

Cardiovascular Health, Adiposity, and Food Insecurity in an Underserved Population

This study investigated associations between cardiovascular health (CVH), adiposity, and food insecurity by race, sex, and health literacy in a sample of 800 underserved patients with obesity (body mass index [BMI] ≥ 30 kg/m²). CVH was assessed using American Heart Association Life’s Simple 7 (LS7) and adiposity was estimated using BMI and waist circumference (WC). Mixed models including interaction terms between food insecurity and sex, race, and health literacy were analyzed for LS7, BMI, and WC. Stratified models were analyzed as indicated by significant interactions. Mean BMI and WC were 37.3 kg/m² (4.6 SD) and 113.5 cm (12.4 SD), respectively. Among patients, 31% were food insecure and 31% had low health literacy. There were significant positive associations between food insecurity and BMI (p = 0.03) and WC (p = 0.03) in the overall sample. In sex-stratified models, women who were food insecure had higher BMI (p = 0.02) and WC (p = 0.007) than their food secure counterparts. Further, food insecure patients with better health literacy had greater BMI (p = 0.004) and WC (p = 0.007) than their food secure counterparts. Results suggest that adiposity is a greater burden in food insecure patients, which may be an important consideration for obesity treatment in underserved populations.

Cardiovascular health literacy and patient-physician communication intervention in women from disadvantaged communities

BACKGROUND

For many women in low socioeconomic status communities, limited health literacy is an obstacle to following medical guidance and engaging in health-promoting behaviours. Low health literacy skills are also associated with an increased risk of cardiovascular disease.

DESIGN

A health literacy intervention was designed through focus groups with women in low socioeconomic status communities. The primary health literacy issue identified was communication challenges at doctors' visits. A unique intervention tailored to the participants' preferences was designed consisting of three workshops conducted in community women's groups in low socioeconomic status Jerusalem communities. The intervention aimed to increase patient-physician communication skills through doctor visit preparation and better visit management, improve perceived efficacy in patient-physician interaction and expand cardiovascular disease knowledge.

METHODS

Questionnaires were completed before and 3 months after the intervention, assessing knowledge of cardiovascular disease risk factors and symptoms, self-report of behaviours in preparations for a doctor's visit, and perceived efficacy in patient-physician interaction.

RESULTS

A total of 407 women from low socioeconomic status communities completed questionnaires. Post-intervention, the percentage of women that reported preparing for doctors' visits increased significantly. Women with initially low levels of perceived efficacy in patient-physician interaction showed a significant increase in perceived efficacy, while initially higher perceived efficacy in patient-physician interaction participants showed a decrease. Participants also demonstrated an increase in knowledge of several risk factors for cardiovascular disease and heart attack symptoms.

CONCLUSIONS

A community-based cardiovascular health literacy intervention improved cardiovascular knowledge and reported doctor visit preparation in low socioeconomic status women as well as increased perceived efficacy in patient-physician interaction among participants with low baseline perceived efficacy in patient-physician interaction. This may lead to improved health care utilisation, preventing chronic illness. Registered at ClinicalTrials.gov, https://www.clinicaltrials.gov , registration number: NCT03203018.

Patient factors driving overuse of cardiac catheterisation: a qualitative study with 25 participants from two German teaching practices

OBJECTIVES

Percutaneous coronary interventions do not provide a benefit over medical therapy for stable patients. However, an overuse of cardiac catheterisation (CC) for stable coronary artery disease (CAD) is documented in Germany and other countries. In this study, we aim to understand patient factors that foster this overuse.

DESIGN

Our study is an exploratory qualitative interview study with narrative, structured interviews. The interviews were analysed using qualitative content analysis by Mayring.

SETTING

The interviews were conducted in two German teaching practices.

PARTICIPANTS

24 interviews with 25 patients were conducted; 17 (68%) patients were male, the average age was 73.9 years (range 53-88 years). All patients suffered from CAD and had undergone at least one CC. Patients with known anxiety disorders were excluded from the study.

RESULTS

The analysis identified six patient factors which contributed to or prevented the overuse of CC: (1) unquestioned acceptance of prescheduled appointments for procedures/convenience; (2) disinterest in and/or lack of disease-specific knowledge; (3) helplessness in situations with varying opinions on the required care; (4) fear of another cardiac event, (5) patient-physician relationship and (6) the patient's experience that repeat interventions did not result in a change of health status or care.

CONCLUSIONS

Conducted in a country with documented overuse of CC, we showed that most patients trusted their physicians' recommendations for repeat coronary angiographies even if they were asymptomatic. Strategies to align physician adherence with guidelines and corresponding patient information are needed to prevent overuse.

A Readability Analysis of Online Cardiovascular Disease-Related Health Education Materials

Background:

Online cardiovascular health materials are easily accessible with an Internet connection, but the readability of its content may limit practical use by patients.

Objective:

The goal of our study was to assess the readability of the most commonly searched Internet health education materials for cardiovascular diseases accessed via Google.

Methods:

We selected 20 commonly searched cardiovascular disease terms: aneurysm, angina, atherosclerosis, cardiomyopathy, congenital heart disease, coronary artery disease, deep vein thrombosis, heart attack, heart failure, high blood pressure, pericardial disease, peripheral arterial disease, rheumatic heart disease, stroke, sudden death, valvular heart disease, mini-stroke, lower extremity edema, pulmonary embolism, and exertional dyspnea. Terms were selected on Google and selected up to 10 results in order of presentation in the search results by reviewing a maximum of 15 pages of Google search results specifically providing education toward patients to yield 196 total patient education articles.

Key Results:

All readability measures assessing grade level measures found the 196 articles were written at a mean 10.9 (SD = 1.8) grade reading level. Moreover, 99.5% of the articles were written beyond the 5th- to 6th-grade level recommended by the American Medical Association.

Conclusions:

Given the prominent use of online patient education material, we consider readability as a quality metric that should be evaluated prior to online publication of any health education materials. Further study of how to improve the readability of online materials may enhance patient education, engagement, and health outcomes. [HLRP: Health Literacy Research and Practice. 2019;3(2):e74–e80.]

Plain Language Summary:

Patients often use Google as a tool for understanding their medical conditions. This study examined the readability of articles accessed via Google for commonly searched cardiovascular diseases and found all articles were written above reading grade levels appropriate for patients. We hope this study will promote the importance of ensuring that online patient education articles are written at appropriate reading levels.

Association between education and major adverse cardiac events among patients with acute coronary syndrome in the Arabian Gulf

Introduction

The objective of this study was to evaluate the association between education and major adverse cardiac events in patients with acute coronary syndrome (ACS) in the Arabian Gulf.

Methods

Data were analysed from 3874 consecutive patients diagnosed with ACS admitted to 29 hospitals in four Arabian Gulf countries from January 2012 to January 2013. Education was defined as any type of formal training from primary school and above. MACE included stroke/transient ischaemic attack (TIA), myocardial infarction (MI), all-cause mortality and readmissions for cardiac reasons.

Results

The overall mean age was 60±13 years and 67% (n=2579) were men. A total of 53% (n=2039) of the patients had some form of school education. Adjusting for demographic and clinical characteristics as well as socioeconomic measures (insurance type and employment), at 12-month follow-up, educated patients were significantly less likely to have had MACE (adjusted OR (aOR): 0.55; 95% CI 0.44 to 0.68; p<0.001) than those with no formal education. The lower rate of events was also consistent across all MACE components: stroke/TIA (aOR: 0.56; 95% CI 0.33 to 0.94; p=0.030), MI (aOR: 0.58; 95% CI 0.38 to 0.86; p=0.008), all-cause mortality (aOR: 0.58; 95% CI 0.39 to 0.87; p=0.009) and readmissions for cardiac reasons (aOR: 0.61; 95% CI 0.48 to 0.77; p<0.001). MACE outcomes were consistent across men and women and across countries.

Conclusions

Education was associated with lower MACE events in patients with ACS in the Arabian Gulf. Interventions promoting healthy lifestyles and management of clinical risk factors for patients with low health literacy are urgently required.

Health literacy in men and women with cardiovascular diseases and its association with the use of health care services - Results from the population-based GEDA2014/2015-EHIS survey in Germany

BACKGROUND

Health literacy (HL), defined as the ability to access, understand, appraise and apply health information, offers a promising approach to reduce the development of cardiovascular diseases (CVD) and to improve the management of CVD in populations.

DESIGN

We used data from nationwide cross-sectional German Health Update (GEDA2014/2015-EHIS) survey. 13,577 adults ≥ 40 years completed a comprehensive standardized paper or online questionnaire including the short form of the European Health Literacy Survey Questionnaire (HLS-EU-Q16).

METHODS

We compared participants with and without CVD with regard to their HL. We also analyzed the association between HL level and health care outcomes among individuals with CVD, i.e. frequency of general practitioner or specialist consultations, hospitalization and treatment delay.

RESULTS

The percentage of "problematic" or "inadequate" HL, defined as "not sufficient" HL, was significantly higher in individuals with CVD compared to without CVD (men 41.8% vs. 33.6%, women 46.7% vs. 33.4%). Having CVD was independently associated with "not sufficient" HL after adjusting for age, education, income, health consciousness and social support (adjusted OR: men 1.36, women 1.64). Among participants with CVD, individuals with "inadequate" HL were more likely to have more than 6 general practitioner consultations (49.3% vs. 28.7%), hospitalization (46.6% vs. 36.0%) in the last 12 months and to experience delay in getting health care because of long waiting lists for an appointment (30.7% vs. 18.5%) compared to participants with "sufficient" HL.

CONCLUSION

"Problematic" or "inadequate" HL is independently associated with CVD and health care use. This is a challenge and an opportunity for both CVD prevention and treatment.

A randomized controlled trial to evaluate utilization of physical activity recommendations among patients of cardiovascular healthcare centres in Eastern Slovakia: study design and rationale of the AWATAR study

Background

Guidelines on modifiable risk factors regarding cardiological patients are poorly implemented in clinical practice perhaps due to low health literacy. Several digital tools for improving lifestyle and behavioural intervention were developed. Our primary aim is to evaluate the effectiveness of a digital exercise prescription tool on the adherence to physical activity recommendations among patients with cardiovascular diseases.

Methods

A randomized controlled trial will be realized in cooperation with Cardiovascular Health Centres in Eastern Slovakia. Patients recruited through their cardiologists, will be randomised at 1:1 ratio to the three-months’ experimental condition or control condition. The experimental group will receive standard lifestyle consultation leading to individually optimized prescription of physical activity. The control group will receive standard, usual-cardio-care lifestyle counselling, also in the domain of physical activity. The digital system will be used for optimized exercise prescription. The primary outcome is a change in the patient’s adherence to exercise recommendations. Data will be collected in both groups prior to consultation and after 3 months.

Discussion

This study protocol presents background and design of a randomized control trial to investigate the effectiveness of a digital system-provide exercise prescription tool on the adherence to physical activity recommendations. An optimized exercise prescription that better reflects patient’s diagnosis, comorbidities and medication can have a significant impact on secondary prevention of cardiovascular disease. This trial can provide important evidence about the effectiveness of digital exercise guidance in everyday practice of cardiovascular healthcare.

Trial registration

The study was registered on 1st November, 2017 and is available online at ClinicalTrials.gov (ID:NCT03329053).

Health literacy in familial hypercholesterolemia: A cross-national study

Background

High rates of inadequate health literacy are associated with maladaptive health outcomes in chronic disease including increased mortality and morbidity rates, poor treatment adherence and poor health. Adequate health literacy may be an important factor in the effective treatment and management of familial hypercholesterolemia, and may also be implicated in genetic screening for familial hypercholesterolemia among index cases. The present study examined the prevalence and predictors of health literacy in familial hypercholesterolemia patients attending clinics in seven countries.

Design

Cross-sectional survey.

Methods

Consecutive FH patients attending clinics in Australia, Brazil, China, Hong Kong, Malaysia, Taiwan and the UK completed measures of demographic variables (age, gender, household income and highest education level) and a brief three-item health literacy scale.

Results

Rates of inadequate health literacy were lowest in the UK (7.0%), Australia (10.0%), Hong Kong (15.7%) and Taiwan (18.0%) samples, with higher rates in the Brazil (22.0%), Malaysia (25.0%) and China (37.0%) samples. Income was an independent predictor of health literacy levels, accounting for effects of age. Health literacy was also independently related to China national group membership.

Conclusions

Findings indicate non-trivial levels of inadequate health literacy in samples of familial hypercholesterolemia patients. Consistent with previous research in chronic illness, inadequate health literacy is related to income as an index of health disparities. Chinese familial hypercholesterolemia patients are more likely to have high rates of inadequate health literacy independent of income. Current findings highlight the imperative of education interventions targeting familial hypercholesterolemia patients with inadequate health literacy.

Health literacy in Italy: a cross-sectional study protocol to assess the health literacy level in a population-based sample, and to validate health literacy measures in the Italian language

INTRODUCTION

Health literacy (HL) concerns the knowledge and competences necessary for people to meet complex health demands. The aims of this study are to assess the level of HL in a sample using the Italian version of the Newest Vital Sign and the association of HL and selected antecedents with health outcomes, and to develop and validate the Italian version of the three Brief Health Literacy Screeners, two subjective numeracy items and the short form and the short-short form of the European Health Literacy Survey Questionnaire.

METHODS AND ANALYSIS

The study adopts a cross-sectional design and is being conducted in Florence, with information collected through telephone interviews. The population-based sample has been randomly selected using the registries of eight general practitioners (GPs). Based on a power calculation, 480 subjects will be included. Participants have been randomly offered two different questionnaires, each containing different HL measures. Data on sociodemographics and important antecedents and consequences of HL will be collected and the distribution of HL levels calculated. The mediating role of HL will be assessed using Preacher and Hayes' model. To assess the concurrent validity of the HL scales, correlation and receiver operating characteristic analyses will be performed.

ETHICS AND DISSEMINATION

The study protocol has been approved by the Ethics Committee of the Area Vasta Centro. Results will be disseminated via scientific journals and conference presentations, and individual data made available to the GPs.
