Functional health literacy and glycaemic control in older adults with type 2 diabetes: a cross-sectional study

Concept analysis of "Insufficient health literacy" in older adults and refinement of a diagnosis proposal

PURPOSE

This study aims to conduct a thorough analysis of the concept of insufficient health literacy (IHL) in older adults and to refine a nursing diagnosis proposal while considering the specific characteristics of this demographic.

METHODS

A comprehensive concept analysis was undertaken using Walker & Avant's method as a framework.

FINDINGS

A systematic search across seventeen databases yielded 29 relevant studies for inclusion. Through analysis, we identified 15 antecedents, 3 attributes, and 7 consequents associated with IHL in older adults.

CONCLUSIONS

The concept analysis brought clarity to the understanding of IHL within older adults, facilitating the refinement of a diagnosis proposal. This process was instrumental in establishing a diagnostic structure that accounts for the unique needs and challenges faced by older adults.

IMPLICATIONS FOR NURSING PRACTICE

The structured diagnosis derived from the concept analysis provides a solid theoretical foundation for nurses specializing in Gerontology. By tailoring care interventions to address the specific requirements of older adults, this framework enhances the quality of nursing practice and contributes to improved patient outcomes in geriatric care settings.

Role of diabetes health literacy, psychological status, self-care behaviors, and life satisfaction in predicting quality of life in type 2 diabetes

One of the factors that can affect the quality of life is the psychological status of people. Also, the psychological status of individuals can be affected by other variables. Therefore, this study was aimed to determine the role of diabetes health literacy, psychological status, self-care behaviors, and life satisfaction in predicting the quality of life in Iranian patients with type 2 diabetes. This cross-sectional study was conducted in Iran in 2021 among 300 patients with type 2 diabetes. The method of selecting the participants in this study was the proportional stratified sampling method. Data collection instruments included six questionnaires of demographic questionnaire and diabetes status, DASS-21 questionnaire (depression, anxiety, and stress), diabetes health literacy scale, self-care behavior questionnaire, satisfaction with life scale (SWLS), and quality of life questionnaire. Statistical methods such as independent sample t test, one-way analysis of variance, linear regression test, and Pearson correlation were used to analyze the data. Based on the results of Pearson correlation test, there was a positive and significant correlation between diabetes health literacy (r = 0.438, p < 0.001), depression (r = - 0.380, p < 0.001), anxiety (r = - 0.355, p < 0.001), stress (r = - 0.423, p < 0.001), and SWLS (r = 0.265, p < 0.001) with quality of life. Based on the results of linear regression, variables of diabetes health literacy, life satisfaction, self -care behaviors, depression, stress, anxiety, age of onset of diabetes and diabetes duration were able to predict 31% of the quality of life (p < 0.001). The results of this study indicated that diabetes health literacy, life satisfaction, stress and the duration of diabetes are able to predict the quality of life of patients with diabetes. Therefore, it is necessary to pay more attention to these effective variables training programs, especially health literacy, the effect of which is very obvious in this study.

Factors associated with poor health literacy in older adults: A systematic review

OBJECTIVES

To identify factors associated with poor health literacy in older adults.

METHODS

A systematic literature review was conducted, employing the descriptors "Aged" and "Health Literacy".

PROSPERO - CRD

42022350140.

RESULTS

Out of 23,500 articles screened, 176 were selected. Several factors associated with poor health literacy in older adults were identified, such as sociodemographic (e.g., advanced age, low educational level, non-white population, and others), social (e.g., poor family/social support, loneliness, social isolation, few social activities, and others), economic (e.g., lower income and/or lower socioeconomic status) and health aspects (e.g., poor health, chronic conditions, mental health challenges, hospitalizations, frailty, physical inactivity, cognitive impairment, and others).

CONCLUSIONS

The factors associated with poor health literacy in older adults identified in this review could contribute to future research, support interventions to improve health literacy, and assist professionals in planning educational activities and public policies.

Pathway analysis of the impact of health literacy, social support and self-efficacy on self-management behaviors in pregnant women with gestational diabetes mellitus

Objective

The purpose of this study was to investigate the pathways by which health literacy (HL), social support, and self-efficacy influence self-management behaviors of pregnant women with Gestational diabetes mellitus (GDM) and the interrelationships between the variables.

Methods

A total of 565 pregnant women with GDM was recruited. The Demographic Characteristics Form, Health Literacy Scale, Perceived Social Support Scale, General Self-efficacy Scale and GDM Self-management Behavior Scale were used for data collection. Descriptive statistics, zero-ordered correlation analysis, and multiple linear regression analysis were performed on the variables; Structural Equation Model (SEM) were constructed for pathway analysis.

Results

A positive correlation was found between health literacy, social support, self-efficacy, and self-management behaviors among pregnant women with GDM after adjusting for age, education level, income level, work status, parity, and family history of diabetes (r ranging from 0.203 to 0.533). A further multiple linear regression analysis showed that functional HL, communicative HL, critical HL, social support, and self-efficacy were all independent influences on self-management behaviors and accounted for 36.3% of the variance. Communicative HL and critical HL explained the strongest self-management behaviors (β = 0.316 and 0.255, respectively, p < 0.001). The SEM model was suitable for χ2/DF = 2.860, RMSEA = 0.060, IFI = 0.953, TLI = 0.943, and CFI = 0.952. The results showed direct positive effects of health literacy on self-management behaviors and self-efficacy, direct positive effects of social support on health literacy and self-efficacy. Social support and self-efficacy have had no significant direct impact on self-management behaviors, but social support may indirectly influence self-management behaviors through the health literacy mediation role.

Conclusion

Healthcare providers should pay attention to the positive impacts of health literacy and social support on self-management behaviors of pregnant women with GDM. Improving the health literacy level of pregnant women with GDM should be the key point of intervention in practice, and the social support system should be fully mobilized to enhance emotional support and life support to promote the improvement of self-management behaviors.

Health literacy and self-efficacy of the elderly with diabetes

Aim

This study aimed to investigate the relationship between health literacy and self-efficacy in the elderly with diabetes.

Method

This cross-sectional study was conducted on 375 diabetic elderly members from a diabetes association, in Iran. Self-efficacy and health literacy questionnaires were used. The Pearson test was used to determine the relationship between self-efficacy and health literacy and linear regression was used to predict self-efficacy by health literacy.

Results

Elderly men and women with diabetes showed a significant difference in terms of health literacy (P = 0.003). People over the age of 70 had a lower level of literacy (P < 0.05). The highest and lowest self-efficacy in the elderly patients were related to taking medications (89.75 ± 17.56) and physical activity (71.38 ± 24.40), respectively. The results of stepwise linear regression showed that health literacy is a predictor of self-efficacy in the diabetic elderly (r2 = 0.55, P < 0.001).

Conclusion

Health literacy is directly related to self-efficacy in older people with diabetes.

Health literacy, self-efficacy, self-care behaviors, and glycemic control among older adults with type 2 diabetes mellitus: a cross-sectional study in Thai communities

BACKGROUND

Properly understanding the health information of people with type 2 diabetes mellitus (T2DM) is the basis for better risk factor management, which also positively affects their quality of life. The aim of this study was to investigate diabetes health literacy (HL), self-efficacy, and self-care behaviors associated with glycemic control among older adults with T2DM in northern Thai communities.

METHODS

A cross-sectional study was conducted among 414 older adults over the age of 60 diagnosed with T2DM. The study was conducted in Phayao Province from January to May 2022. Simple random sampling of the patient list for the Java Health Center Information System program was used. Questionnaires were used to collect data on diabetes HL, self-efficacy, and self-care behaviors. Blood samples were tested for estimated glomerular filtration rate (eGFR) and glycemic controls, such as fasting blood sugar (FBS) and glycated hemoglobin (HbA1c).

RESULTS

The mean age of participants was 67.1 years. FBS (mean ± SD = 108.5 ± 29.5 mg/dL) and HbA1c (mean ± SD = 6.6 ± 1.2%) levels were found to be abnormal in 50.5% (≥ 126 mg/dL) and 17.4% (≥ 6.5%) of the subjects, respectively. There was a strong correlation between HL and self-efficacy (r = 0.78), HL and self-care behaviors (r = 0.76), and self-efficacy and self-care behaviors (r = 0.84). The eGFR was significantly correlated with diabetes HL (r = 0.23), self-efficacy (r = 0.14), self-care behaviors (r = 0.16), and HbA1c (r = -0.16) scores. Linear regression after adjusting for sex, age, education, DM duration, smoking, and drinking alcohol showed that FBS level was inversely associated with diabetes HL (Beta = -0.21, R² = 11.0%), self-efficacy (Beta = -0.43, R² = 22.2%), and self-care behavior (Beta = -0.35, R² = 17.8%), whereas HbA1C level was negatively associated with diabetes HL (Beta = -0.52, R² = 23.8%), self-efficacy (Beta = -0.39, R² = 19.1%), and self-care behavior (Beta = -0.42, R² = 20.7%).

CONCLUSION

Diabetes HL was related to self-efficacy and self-care behaviors in elderly T2DM patients and was shown to influence their health, including glycemic control. These findings suggest that implementing HL programs to build competence in self-efficacy expectations is important for contributing to improvements in diabetes preventive care behaviors and HbA1c control.

Does Health Literacy Have an Impact on Adherence to Diabetes Mellitus Treatment?

(1) Background: Health literacy is the intersection of general literacy, health, and healthcare, but it can also incorporate elements of other types of literacies to varying degrees. The notion of literacy surfaced from the fear that individuals would require more than general literacy skills to manage the complexities of health and health system issues. There is a substantial overlap between general literacy and health literacy. Diabetes patients frequently misinterpret medication instructions, resulting in non-adherence and poor health outcomes. (2) Aim: This study sought to review the literature on the impacts of health literacy on adherence and compliance to diabetes mellitus treatment. (3) Methods: A Narrative Literature Review method was used to identify, analyze, assess, and interpret the available information on health literacy regarding prescribed medication instructions. The following databases and search engines were used to locate the literature: electronic databases, search engines, and hand searches. Fifty-three (53) quantitative and qualitative studies and two books were reviewed. (4) Result: The review pointed out the following: the importance of health literacy, the implications of health illiteracy versus medication non-adherence, factors influencing health literacy versus medication adherence, and the interventions to improve medication non-adherence. (5) Conclusion: Relatively few studies have been conducted on how people living with diabetes should carry out their treatment. Therefore, more research on how people living with diabetes carry out their treatment daily is required. (6) Contributions: This study has identified that health literacy plays a role in adherence to treatment and contributes to improved health outcomes.

The Multidimensionality of Low Health Literacy in Older Adults: A Scoping Review of International Studies

This scoping review aims to map the dimensions encompassing the low health literacy (HL) of older adults, describing their respective causes and consequences. A three-step search strategy was conducted using 16 databases from nine portals and reference lists. Of the 4,259 identified studies, 2,845 were screened and 29 (1%) were included. Studies were published between 1999 and 2021, most of them in English (86.2%), from the American continent (48.3%) and with observational design (86.2%). Four dimensions encompassing the low HL of older adults were mapped: (1) patient dimension, (2) healthcare system dimension, (3) social/economic dimension, and (4) health condition dimension. This review highlights specific dimensions encompassing the low literacy in older adults with evidence about its causes and consequences. These results can guide future research and evidence-based practice involving HL of older adults.

Health literacy and health outcomes among older patients suffering from chronic diseases: A moderated mediation model

Introduction

Aging brings with an increased risk of chronic diseases among older adults, which could affect health outcomes. Evidence has showed that health literacy is associated with health outcomes. However, limited studies explore the underlying mechanism between health literacy and health outcomes. Hence, this study aimed to determine whether self-efficacy for managing chronic disease mediates the relationship between health literacy and health outcomes among older patients with chronic diseases, and to explore whether disease duration moderates the relationship between health literacy, self-efficacy for managing chronic disease, and health outcomes.

Methods

Participants were recruited from tertiary hospitals in Zhejiang Province, China from May 2019 to June 2020 using a convenience sampling method. A total of 471 older patients with chronic diseases completed questionnaires measuring demographics, disease-related information, health literacy, self-efficacy for managing chronic disease, and health outcomes. The mediation effect was examined using the structural equation model method, based on the bias-corrected bootstrapping method. The moderation effect was tested by the multiple-group analysis.

Results

A good fit model suggested that self-efficacy for managing chronic disease partially mediated the relationships between health literacy and health outcomes. In addition, disease duration moderated the relationships between health literacy, self-efficacy for managing chronic disease, and health outcomes.

Discussion

The findings highlight that adequate health literacy improved health outcomes among older patients with chronic diseases, which was further promoted by self-efficacy for managing chronic diseases. Moreover, a long disease duration could enhance the effect.

Low health literacy and quality of life in patients with systemic arterial hypertension

Purpose

Evaluate the level of health literacy and quality of life of patients with hypertension.

Methods

A cross-sectional, observational study was carried out in the Northeast region of Brazil with 105 patients with hypertension through the SAHLPA-18, S-TOFHLA and MINICHAL tests.

Results

For both literacy tests applied, it can be observed that about 60% of the interviewed patients did not present adequate health literacy. It was found that factors such as increasing age, lower economic class and lower education were associated with a lower level of health literacy. In the evaluation of the quality of life by the MINICHAL, 46.7% of the patients reported that hypertension interferes with quality of life. It was also possible to show that the time of diagnosis (p = 0.04) and the economic class (p = 0.008) influence the quality of life.

Conclusion

Hypertension is a chronic condition that requires continuous treatment and has potential risks of evolving with fatal and non-fatal complications that can affect the patients' quality of life. The data presented reflect the difficulty in understanding and processing health information, which may directly impact on the therapeutic management of hypertension.

Associations of functional health literacy with socioeconomic and demographic status among Filipinos

BACKGROUND

Health literacy determines an individual's decision-making process in providing judgment concerning appropriate healthcare. Considering the various purposes of literacy for people, functional health literacy (FHL) was identified as a type of literacy that is measured by the application of literacy skills to health-related materials as a result of health education. The objective of this study was to identify the possible socio-demographic correlates of FHL of Filipinos.

METHODS

A cross-sectional survey was conducted among 2,303 Filipinos aged 15 to 70 years old in 2018-2019 utilizing the National Health Literacy Survey. Functional health literacy was determined using the FHL-5 Test which measured prose, document, and numeracy skills. Descriptive analysis presented socio-demographic characteristics and level of FHL. Log-binomial regression was used to estimate associations of FHL adequacy with socio-demographic characteristics.

RESULTS

Overall, the study involved 1,997 (86.7%) qualified participants. Most of them demonstrated prose literacy skills and had adequate FHL. Adjusted regression analyses showed that participants with a college-level education (Adjusted prevalence ratio [APR]: 1.43, 95% confidence interval [95% CI] 1.27-1.60), categorized under domestic service occupation (APR 1.19, 95% CI: 1.03-1.37), and those residing in urban areas (APR: 1.14, 95% CI 1.06-1.24) were significantly more prevalent in exhibiting FHL adequacy. In contrast, male participants and individuals aged 60 years or above were less likely to demonstrate FHL adequacy.

CONCLUSIONS

The study presents a baseline assessment of the functional health literacy level, measured using the FHL-5 Test, of adults in the Philippines. Majority of the participants demonstrated FHL adequacy, with relatively higher scores in prose than numeracy literacy. The measurement of FHL adequacy can inform policies on methods of health education and communication, emphasizing the need to stratify the audience based on socio-demographic characteristics and adapt the content and design of informational materials for population-based health educational programs.

Factors affecting the health literacy status of patients with type 2 diabetes through demographic variables: A cross-sectional study

BACKGROUND

Health literacy (HL) is the ability of a person to acquire the process, understand the necessary health information, and make the health services needed for conscious health decisions. Besides, diabetes is the most common metabolic disorder that affects patients' quantity and quality of life. This study focused on determining the factors that affect the HL status of patients with type 2 diabetes (T2D) through the role of the demographic variables.

MATERIALS AND METHODS

This descriptive-analytical research survey recruited a sample based on 280 patients with T2D at the Diabetes Research Center of Ayatollah Taleghani Hospital in Kermanshah in 2020. This study selected patients with T2D using a simple random sampling technique. The study applied the demographic information questionnaire and the Functional, Communicative, and Critical HL Scale to collect data from patients with T2D. This study used the SPSS version 23 on the received data sets to perform statistical analysis, including t-test, analysis of the variance, and multiple regression, to predict the factors affecting HL among diabetes patients.

RESULTS

The study results showed that the mean age of the participating patients with T2D was 55.80 ± 13.04. The results indicated the mean score and standard deviation of total HL score in patients with T2D 2.70 ± 0.44. The findings specified a statistically significant relationship between HL, gender, education, occupation, income, and place of residence. Results indicated that β-coefficients of the multiple regression analysis and the income variable (β = 0.170), age (β = 0.176), and employment variable (β = 0.157). These are the most predictive of the HL of patients with T2D.

CONCLUSION

The results of this study specified that the HL rate of individuals with diabetes type 2 is average. The potential communicative and critical HL influence is essential for communication and education for diabetes patients in the primary health-care system settings. The findings indicate that communicative and critical HL related to patients' management and functional HL looks passable in this study.

The Relationships Among Health Literacy, Illness Perception, and Diabetes Self-Care in Korean-Speaking Immigrants With Diabetes

Diabetes self-care is explained as an illness-related coping behavior. Health literacy is an important predictor in self-care behaviors. However, little is known about their association with illness perception in Korean immigrants with diabetes. This study aimed to examine the relationships among health literacy, illness perception, and diabetes self-care in Korean-speaking immigrants with diabetes. This cross-sectional study was conducted in 2020. A convenience sample of 52 Korean adults with diabetes in Dallas-Fort Worth areas completed a survey. Data were analyzed using SPSS (version 25) with statistical significance at α < .05. The mean of health literacy was high (11.1, SD = 1.1, ranges 0-12) although risk of type II error with the small sample size. There were no statistically significant associations between health literacy, illness perception, and diabetes self-care. Language barriers are considered a literacy issue, but health literacy and limited English proficiency must be approached differently by health care providers.

Letramento funcional em saúde de usuários da atenção primária de Altamira, Pará

Introdução: O Letramento Funcional em Saúde (LFS) está associado à capacidade dos pacientes em compreender e utilizar seus conhecimentos em saúde no âmbito do autocuidado e na promoção a saúde. Por isso, torna-se essencial reconhecer o nível de LFS e identificar os fatores que o influenciam. Objetivo: Analisar o nível de letramento funcional em saúde (LFS) de usuários de Unidades de Saúde da Família (USF) na área urbana de Altamira (PA). Métodos: Estudo transversal no qual a coleta de dados ocorreu entre agosto de 2018 e dezembro de 2019 em 12 USF da área urbana. O cálculo amostral foi realizado com base na população urbana de Altamira registrada pelo Censo de 2010. Utilizou-se intervalo de confiança de 95% com margem de erro de 5% e prevalência de achados de 50% em uma população semelhante, encontrando-se assim o valor de 382. Os participantes foram entrevistados a fim de se coletarem informações sobre dados sociodemográficos, e posteriormente foi aplicado um questionário baseado na versão brasileira do Short Test of Functional Health Literacy (S-TOFHLA), instrumento utilizado para a mensuração do LFS. O coeficiente de correlação de Pearson, o teste qui-quadrado, o teste G e a odds ratio foram utilizados para verificar a relação entre a pontuação do S-TOFHLA e os dados sociodemográficos. Além disso, uma análise de regressão múltipla foi realizada para predizer os fatores que interferem no LFS. Por fim, o teste ANOVA buscou diferenças entre os níveis de LFS dos usuários nas USF analisadas. Resultados: Foram incluídos no estudo 400 participantes, dos quais 59% apresentaram LFS adequado, 16,5% limítrofe e 24,5% inadequado. As variáveis, grau de escolaridade, idade e renda foram associadas ao LFS na população estudada, predizendo, respectivamente, em 46, 26 e 17% o desempenho no teste S-TOFHLA. Baixa escolaridade e baixa renda aumentam o risco de indivíduos possuírem LFS insatisfatório em cinco e quatro vezes, nessa ordem. Por fim, foram encontradas diferenças entre os níveis de LFS dos usuários das USF analisadas. Conclusões: A população da área urbana de Altamira apresentou alta prevalência de LFS insatisfatório. Sendo assim, no intuito de aumentar os resultados satisfatórios em saúde, os profissionais da região devem adequar as suas formas de comunicação e linguagem às necessidades dos usuários das USF, observando que a adequação da equipe pode trazer melhorias para o entendimento das informações e oportunizar melhores condições de recuperação e autocuidado em saúde.

Effects of the Alpha-Health intervention on elderly’s health literacy in primary health care

ABSTRACT Objective: to assess the effects of the Alpha-Health intervention on health literacy and health habits of elderly people linked to primary care, when compared to usual health care. Methods: a quasi-experimental investigation, with mixed methods, with 21 elderly individuals in each group. Alpha-Health was performed by a nurse for five months. The Short Assessment of Health Literacy for Portuguese Speaking Adults, Health Literacy and questions about health habits were used. In the quantitative analysis, the GEE Model was used, and in the qualitative, thematic analysis. Results: there was an interaction effect on health literacy scores. Health habits such as vaccination, three meals a day and meat consumption had a statistically significant interaction effect. In the qualitative stage, development in skills of accessing, communicating and assessing information was observed as well as stability in the ability to understand. Conclusions: Alpha-Health is an important device for developing elderly’s health literacy.

Improving health literacy among older people through primary health care units in Brazil: feasibility study

There are only a small number of reported intervention studies to improve health literacy among older populations. This paper reports on a study designed to investigate the feasibility and potential impact on health literacy and health practices of embedding an intervention programme to improve health literacy with older people through established primary health care units (PHCUs) in a disadvantaged urban community in Brazil. This investigation utilized a quasi-experimental design, with 42 participants recruited for the intervention group and comparison group. The Alfa-Health Program was offered by a nurse in a PHCU as part of the public universal health system over a period of 5 months, and was compared for its impact on a range of health literacy and self-reported health outcomes with routine health care available for older people. The intervention achieved relatively high levels of participation, and positive feedback from participants. Some improvements in vaccination rates, health literacy and reported health behaviours related to food choices and physical activity were observed. The intervention made good use of existing facilities; the content and methods were well received by the participants. However, there were some difficulties in recruitment and in retention of participants. The study has demonstrated the practical feasibility of delivering a comprehensive health education programme designed to improve health literacy in a PHCU in Brazil.

Association of health literacy and other risk factors with glycemic control among patients with type 2 diabetes in Kuwait: A cross-sectional study

BACKGROUND

Poor health literacy (HL) has received much attention recently as a risk factor for poor health outcomes especially among patients with chronic diseases. The degree to which HL affects health outcomes is unknown among patients with type 2 diabetes mellitus (T2DM) in Kuwait. This study aimed to investigate the association between HL and glycated hemoglobin (HbA1c) among patients with T2DM.

METHODS

356 patients with T2DM were selected from 27 primary care clinics covering the state of Kuwait. HL was measured by the Short Test of Functional Health Literacy in Adults (STOFHLA). Prevalence of uncontrolled HbA1c was estimated and its association with HL was modeled and tested using Poisson regression with log-link function and robust variance-covariance matrix, while adjusting for several confounders.

RESULTS

The prevalence of uncontrolled HbA1c was 77.8%. Among those with inadequate or marginal HL, about 50.7% have uncontrolled HbA1c. The prevalence of uncontrolled HbA1c among those on diet alone was 36.3% lower compared to those on mixed treatment regimen (APR = 0.637, 95% CI: 0.455-0.891, PV = 0.008). The prevalence of uncontrolled HbA1c among patients on oral hypoglycemic (OH) drugs alone was 22.3% lower compared to those on mixed treatment (OH plus Insulin) regimen (APR = 0.777, 95% CI: 0.697-0.865, PV < 0.001). For every one-year increase in age, there is 1.4% reduction in the prevalence of uncontrolled HbA1c (APR = 0.986, 95% CI: 0.978-0.994, PV < 0.001). For one STOFHLA score increase, there is 0.3% reduction in the prevalence of uncontrolled HbA1c (APR = 0.997, 95% CI: 0.994-1.00, PV = 0.055). Finally, for every year increase since T2DM onset, there is 1.1% increase in the prevalence of uncontrolled HbA1c (APR = 1.011, 95% CI: 1.003-1.019, PV = 0.008).

CONCLUSIONS

The prevalence of uncontrolled HbA1c among patients with T2DM in Kuwait is high. Half of T2DM with inadequate or marginal HL have uncontrolled HbA1c. Patients on diet alone or OH alone have lower prevalence of uncontrolled HbA1c compared to those on mixed treatment regimen. Older T2DM patients or those with higher STOFHLA score have lower prevalence of uncontrolled HbA1c, while those with longer T2DM onset have higher prevalence of uncontrolled HbA1c. Future interventions should focus on younger patients, improve HL, and establish better communications between physicians and patients with T2DM for better glycemic control.

Effects of Health Literacy Intervention on Health Literacy Level and Glucolipid Metabolism of Diabetic Patients in Mainland China: A Systematic Review and Meta-Analysis

OBJECTIVE

To systematically evaluate the effects of health literacy intervention on health literacy level and glycolipid metabolism of people with diabetes in mainland China.

METHODS

A systematic review of journal articles discussing diabetes and health literacy was performed by searching PubMed, Embase, the Science Citation Index Expanded (SCIE) database of Web of Science, the China National Knowledge Infrastructure (CNKI) database, the Chinese Scientific and Technical Journals database (CQVIP), and the Wanfang database. Cochrane Effective Practice and Organization of Care Review Group (EPOC) standards were applied for quality assessment. A meta-analysis was performed using Stata 12.0 software.

RESULTS

A total of 44 articles, including seven controlled before-and-after trials (CBAs), 27 randomized controlled trials (RCTs), and 10 nonrandomized controlled trials (non-RCTs), were included. The results showed that (1) health literacy level in the intervention group was improved compared with the preintervention and the control group; (2) fasting plasma glucose (FPG) (standardized mean difference (SMD) = -1.85, 95% CI: -2.28, -1.42), 2-hour plasma glucose (2hPG) (SMD = -2.18, 95% CI: -2.68, -1.68), and HbA1c (weighted mean difference (WMD) = -1.21, 95% CI: -1.48, -0.94) were significantly reduced in the intervention group; (3) total cholesterol (TC) (WMD = -0.43, 95% CI: -0.64, -0.23) was significantly reduced in the intervention group, although there were no statistically significant differences for triglycerides (TG) (WMD = -0.34, 95% CI: -0.73, 0.05), low-density lipoprotein cholesterol (LDL-C) (WMD = -0.20, 95% CI: -0.46, 0.07), or high-density lipoprotein cholesterol (HDL-C) (WMD = -0.06, 95% CI: -0.29, 0.17).

CONCLUSION

Intervention based on health literacy can effectively improve health literacy levels and reduce glucose metabolism and TC level among people with diabetes mellitus, although it has no significant effect on TG, LDL-C, or HDL-C.

Conclusão e implicações para a prática o letramento funcional em saúde inadequado em idosos portadores de doenças crônicas, muitas vezes responsáveis pelo seu autocuidado, pode contribuir para agravos na condição de saúde e doença dessa população, sendo relevante seu reconhecimento para o estabelecimento de estratégias e ações que visem melhores resultados na produção do cuidado.

Adequacy of health literacy and its effect on diabetes self-management: a meta-analysis

This study evaluated the role of health literacy (HL) in the self-management of diabetes. A literature search was conducted in electronic databases and studies were selected using precise eligibility criteria. A meta-analysis was conducted to estimate the HL adequacy rate, factors affecting the adequacy of HL and correlations between HL and diabetes self-management variables. Thirty-three studies were included in the analysis. The HL adequacy rate was 67% (95% confidence interval (CI) 57, 76). Compared with patients with inadequate HL, patients with adequate HL were younger (mean difference -5.2 years; 95% CI -7.2, -3.2; P<0.00001), more likely to have a high school or higher level of education (odds ratio (OR) 8.39; 95% CI 5.03, 13.99]; P<0.00001) and were less likely to belong to a low-income group (OR 0.36; 95% CI 0.23, 0.56; P<0.00001). HL was positively correlated with self-monitoring (r=0.19; 95% CI 0.11, 0.27; P<0.00001), dietary and physical care (r=0.12; 95% CI 0.07, 0.18; P=0.009), diabetes knowledge (r=0.29; 95% CI 0.09, 0.45; P<0.001), self-efficacy (r=0.28; 95% CI 0.15, 0.41; P<0.00001), self-care (0.24; 95% CI 0.16, 0.31; P<0.00001), formal education (r=0.35; 95% CI 0.18, 0.53; P<0.00001) and social support (r=0.2; 95% CI 0.07, 0.33; P<0.00001). Patient age (r=-0.28; 95% CI -0.39, -0.17; P<0.00001) was inversely correlated with HL. In conclusion, 67% of diabetes patients had adequate HL, with a higher rate among better educated and higher income groups. HL had a statistically significant but weak positive correlation with diabetes self-management variables.

Association between health literacy and glycemic control in elderly patients with type 2 diabetes and modifying effect of social support

OBJECTIVE

To investigate the association between inadequate functional health literacy, considering the Short Assessment of Health Literacy for Portuguese-speaking Adults, and glycemic control in elderly patients with type 2 diabetes, and to examine this association in low social support settings, according to Medical Outcomes Study .

METHODS

Cross-sectional study conducted at the diabetes referral center of a university hospital. Participants were recruited among type 2 diabetes patients aged 60 years or older, between May 2013 and November 2014. The primary outcome was the most recent glycated hemoglobin value measured within the last 6 months.

RESULTS

A total of 398 elderly patients with type 2 diabetes were evaluated. Of these, 232 were not eligible to participate. The final sample comprised 166 participants. Hierarchical multiple linear regression was performed. The following variables were entered in three blocks: sociodemographic characteristics, clinical variables and health literacy scores. Regression analysis of the interaction between health literacy and social support as a determinant of glycemic control was also performed. Mean age of subjects was 68.0 years (standard deviation of 5.9). Mean glycated hemoglobin value was 8.5% (standard deviation of 1.4). Short assessment of health literacy for Portuguese speaking adults score was independently associated with glycated hemoglobin (B=-0.059; p=0.043). The interaction between social support and health literacy score (p=0.003) was a determinant of glycemic control.

CONCLUSION

Health literacy is associated with glycemic control. Social support may modify the relation between health literacy and glycemic control.

Association of Health Literacy and Nutritional Status Assessment with Glycemic Control in Adults with Type 2 Diabetes Mellitus

While the role of medical and nutrition factors on glycemic control among adults with type 2 diabetes mellitus (T2DM) has been well-established, the association between health literacy (H.L.) and glycemic control is inconsistent. This study aims to determine the association of H.L. and nutritional status assessments with glycemic control in adults with type 2 diabetes mellitus. A total of 280 T2DM respondents (mean (SD) age = 49.7 (10.3) years, Glycated hemoglobin (HbA1c) = 9.9 (2.6) %, and Body Mass Index = 32.7 (15.1) kg/m²) were included in this study. A short-form Test of Functional Health Literacy in Adults (S-TOFHLA) assessed the H.L. levels. Nutritional status assessments included client history, glycemic control, anthropometric, and biochemical data. The mean (S.D.) H.L. score was 45.7 (24.6), with 56% of the respondents had inadequate H.L. Inadequate H.L. was more common among those females; housewives, low education, received oral antidiabetic therapy, and shorter diabetes duration. Respondents with inadequate H.L. were significantly older and had higher HbA1c than those with marginal and adequate H.L. Meanwhile, respondents with inadequate and marginal H.L. levels had significantly higher total cholesterol, LDL-cholesterol, and systolic blood pressure than the respondents with adequate H.L. Low H.L. scores, self-employment status, received dual antidiabetic therapy (insulin with oral agents), received insulin alone, and had higher fasting blood glucose explained about 21% of the total variation in HbA1c (adjusted R² = 0.21; p < 0.001). Respondents with inadequate H.L. had poor glycemic control. The H.L. scores, together with nutritional status assessments, were the factors that predicted poor glycemic control among adults with T2DM.

Health literacy assessment: Translation and cultural adaptation to the Portuguese population

RATIONALE, AIMS, AND OBJECTIVES

Health literacy (HL) has been widely referenced as a determinant of health outcomes, making the assessment of low HL a fundamental step to plan educational interventions. This study aimed to translate and adapt the Short Assessment of Health Literacy-Spanish and English (SAHL-S&E) questionnaire into European Portuguese.

METHODS

The SAHL-S&E questionnaire was translated using the recommendations of the International Society for Pharmacoeconomics and Outcomes Research. One hundred fifty-three Portuguese native speakers aged over 18 years old were included in this study, enrolled among users of community pharmacies in the Algarve region (Portugal).

RESULTS

The translation of the questionnaire used showed a good internal consistency (Cronbach α: .812), and a statistically significant (F = 5.05 P < .001) interrater reliability. Over a third of subjects (37.9%) achieved a score less than or equal to 14, which is indicative of low HL.

CONCLUSION

This tool, intended to be used in the European Portuguese population, can be used for low HL screening.

Exploring the Influencing Factors of Health Literacy among Older Adults: A Cross-Sectional Survey

Background and Objectives: To investigate the health literacy (HL) among older adults in Taiwan, we referenced an existing integrated model of HL to confirm the influencing factors of HL in older adults. We propose this study to examine the personal, situational, and socioenvironmental factors influencing HL among older adults. Materials and Methods: A cross-sectional survey was conducted at a district hospital and affiliated community center in northern Taiwan from August 2016 to May 2017. This study used the Mandarin Chinese version of the European Health Literacy Survey Questionnaire (EU-Q47). We designed three models based on the three domains of HL. Model 1 assesses personal factors. Model 2 incorporates situational factors. Model 3 adds the socioenvironmental factor. Results: We recruited 161 participants aged over 65 years. Most adults in this study had limited overall HL. The final regression model revealed that age >85 years, unknown insurance status, and dominant spoken dialect of Hakka or Taiwanese were significantly associated with higher scores of HL. Conclusions: Our study results may help clinicians with early identification of older adults at high risk for poor HL and help health administrators establish geriatric policies and health education plans.

Distal Symmetric and Cardiovascular Autonomic Neuropathies in Brazilian Individuals with Type 2 Diabetes Followed in a Primary Health Care Unit: A Cross-Sectional Study

The paucity of epidemiological data regarding diabetes complications in Brazil motivated us to evaluate the prevalence rates of distal symmetric polyneuropathy (DSP) and of cardiovascular autonomic neuropathy (CAN) in individuals with type 2 diabetes (T2D) followed in a primary care unit. A total of 551 individuals (59.3% women, 65 years old; diabetes duration of 10 years; HbA1c of 7.2%, medians) were included in this cross-sectional study. DSP was diagnosed by sum of the Neuropathy Symptoms Score (NSS) and Modified Neuropathy Disability Score (NDS) and by the Semmes-Weinstein monofilament. CAN was diagnosed by cardiovascular autonomic reflex tests combined with spectral analysis of heart rate variability. The prevalence rates of DSP were 6.3% and 14.3%, as evaluated by the sum of NSS and NDS and by the Semmes-Weinstein monofilament, respectively. Those with DSP diagnosed by monofilament presented longer diabetes duration, worse glycemic control and a higher stature. The prevalence rates of incipient and definitive CAN were 12.5% and 10%, respectively. Individuals with definitive CAN presented a higher frequency of hypercholesterolemia and of arterial hypertension. The higher prevalence rate of DSP with the use of the monofilament suggests that it may be a more appropriate tool to diagnose DSP in the primary care setting in Brazil.

Health literacy and glycemic control in patients with diabetes: a tertiary care center study in Brazil

BACKGROUND

The primary objective of our study was to determine which factors influence health literacy (HL) in patients with type 1 diabetes (T1D) and type 2 diabetes (T2D), and the secondary one was to evaluate the influence of HL on glycemic control.

METHODS

This was an observational, cross-sectional study with 347 patients (144 with T1D and 203 with T2D), conducted between December 2014/December 2017. Data were obtained from medical records and/or questionnaire. The short test of Functional Health Literacy (S-TOFHLA) was used to evaluate HL.

RESULTS

Age and years of school attendance were the most important variables associated with better performance in S-TOFHLA mainly in patients with T1D. A correlation between age and years of school attendance with S-TOFHLA score was observed in both groups of patients. After an unadjusted analysis, more patients with T1D presented adequate HL [119 (82.6%) vs 87 (44.8%, p < 0.001)]. Patients with T1D had higher scores than patients with T2D (84.4 ± 21.4 vs 61.6 ± 26.8 points, p < 0.001), respectively. This difference did not persist after adjustment for age and years of school attendance (73.04 ± 2.14 ± vs 70.04 ± 1.76 points) respectively, p = 0.348). No difference was found in HbA1c levels according to S-TOFHLA. All patients with T1D and HbA1c levels < 7.0% (53 mmol/mol) had adequate HL.

CONCLUSIONS

A considerable number of patients with either T1D or T2D did not have adequate HL. Overall, age and years of school attendance were the most important variables associated with better performance of S-TOFHLA. Although no difference was found in HbA1c levels according to S-TOFHLA, patients with T1D who self-reported as White, with more years of school attendance, and higher HL score reached more frequently a good glycemic control. Finally, in addition to therapeutic regimens, approaches on diabetes management should also include patients' HL evaluation along with psychological and social aspects.

The Association of Health Literacy Level with Self-Care Behaviors and Glycemic Control in a Low Education Population with Type 2 Diabetes Mellitus: A Cross-Sectional Study in Iran

INTRODUCTION

Promoting Health Literacy (HL) can be a priority in strategic healthcare planning of the countries. Low HL is prevalent in some societies which make barriers to successful self-care of diseases. The aim of this study was to examine the association of HL with self-care behaviors and glycemic control in a low education population with type 2 diabetes mellitus.

METHODS

This cross-sectional study was conducted in Sarab city, Iran. The 192 participants were patients diagnosed as type 2 diabetes and with low level of education. Convenient sampling method was applied and the participants were chosen by their medical records in health-care centers. To collect data a valid and reliable tool was used based on HL dimensions and self-care behaviors. Using hierarchical logistic regression, the possible association of variables with self-care behaviors and glycemic control was assessed.

RESULTS

The mean age of study participants was 58.12 (±11.83) years. A 28.8% of the variation in the self-care behaviors is explained by the HL and the demographic variables (R= 0.288%; p-value<0.05). Furthermore, decision-making was the strongest predictor of self-care behaviors (β= 0.451). Approximately 80% of the variation in the HbA1c is explained by the HL, self-care behaviors, and the demographic variables (R= 0.804%; p-value<0.05).

CONCLUSION

This study revealed that the HL dimensions predicted approximately one-fourth of self-care behaviors and the self-care behaviors and HL dimensions about eight-tenths of HbA1c in this population. These findings call for the need for interventional programs on HL to improve the self-care behaviors and HbA1c control.

The Brazilian Portuguese Version of the DISCERN Instrument: Translation Procedures and Psychometric Properties

OBJECTIVES

To report on the translation procedures and psychometric properties of the DISCERN tool in Brazilian Portuguese.

METHODS

Three people translated the DISCERN from English into Brazilian Portuguese. A committee of experts and community representatives evaluated the quality of the 3 versions in 2 online voting rounds. Two native speakers back-translated the questionnaire into English. We compared these versions to the original DISCERN and made small adjustments. The final Brazilian Portuguese version of DISCERN was tested twice by journalism students to evaluate the quality of a text about smoking cessation treatments. We evaluated participants' health literacy with the Short Assessment of Health Literacy for Portuguese-Speaking Adults (SAHL-PA) tool, assessed the internal consistency of the translated questionnaire with the Cronbach test, and measured its reproducibility with the intraclass correlation coefficient (ICC). We then investigated the relationship between DISCERN and SAHL-PA scores and demographic variables.

RESULTS

The participants (n = 126) had no difficulty in using the questionnaire. Cronbach's alpha was 0.865 (95% confidence interval [CI], 0.826-0.898), and the ICC between the 2 evaluations was 0.845 (CI 0.717-0.912). The mean health literacy of the participants was adequate. There was no correlation between the DISCERN score and the SAHL-PA score, age, or sex (P > .05).

CONCLUSIONS

The Brazilian Portuguese version of the DISCERN questionnaire has excellent internal consistency and good reproducibility. The evaluators' ages, sex, and health literacy did not interfere with the score resulting from the evaluation of the quality of the text.

Participatory learning and action to address type 2 diabetes in rural Bangladesh: a qualitative process evaluation

BACKGROUND

Diabetes is 7th largest cause of death worldwide, and prevalence is increasing rapidly in low-and middle-income countries. There is an urgent need to develop and test interventions to prevent and control diabetes and develop the theory about how such interventions can be effective. We conducted a participatory learning and action (PLA) intervention with community groups in rural Bangladesh which was evaluated through a cluster randomised controlled trial. There was a large reduction in the combined prevalence of type 2 diabetes and intermediate hyperglycaemia in the PLA group compared with the control group. We present findings from qualitative process evaluation research to explore how this intervention was effective.

METHODS

We conducted group interviews and focus group discussions using photovoice with purposively sampled group attenders and non-attenders, and intervention implementers. Data were collected before the trial analysis. We used inductive content analysis to generate theory from the data.

RESULTS

The intervention increased the health literacy of individuals and communities - developing their knowledge, capacity and self-confidence to enact healthy behaviours. Community, household and individual capacity increased through social support and social networks, which then created an enabling community context, further strengthening agency and enabling community action. This increased opportunities for healthy behaviour. Community actions addressed lack of awareness about diabetes, gendered barriers to physical activity and lack of access to blood glucose testing. The interaction between the individual, household, and community contexts amplified change, and yet there was limited engagement with macro level, or 'state', barriers to healthy behaviour.

CONCLUSIONS

The participatory approach enabled groups to analyse how context affected their ability to have healthy behaviours and participants engaged with issues as a community in the ways that they felt comfortable. We suggest measuring health literacy and social networks in future interventions and recommend specific capacity strengthening to develop public accountability mechanisms and health systems strengthening to complement community-based interventions.

The association of diabetes literacy with self-management among older people with type 2 diabetes mellitus: a cross-sectional study

Background

Diabetes has become one of public health problem up until now. As the disease progressed, it might lead to increasing complication as well as death related to them. Diabetes as chronic disease in older people can lead to more vulnerable conditions if they fail to carry out a proper diabetes self-management. Diabetes literacy is an internal factor affecting how the older people go about their diabetes management routines. This study aimed to describe diabetes literacy of the older people and identify the relation of diabetes literacy to diabetes self-management of the older people with T2DM in selected areas of Depok City, West Java, Indonesia.

Method

A cross-sectional observational study was utilized and used 106 samples of older people individuals with T2DM, all of whom were chosen via cluster sampling. This research took place in five selected areas under the supervision of three public health center in Depok City. The data were analyzed using a bivariate t-independent test, the Pearson product-moment correlation, and logistic regression for multivariate analysis to determine the relationship of independent and dependent variable.

Result

This research shows a significant correlation between diabetes literacy and diabetes self-management (p = 0,011).

Conclusion

Diabetes self management is associated with diabetes literacy in older people with type 2 diabetes mellitus. Diabetes literacy should be considered when assessing and addressing diabetes-specific health education needs.

The Role of Health Literacy in Diabetes Knowledge, Self-Care, and Glycemic Control: a Meta-analysis

BACKGROUND

Empirical evidence on how health literacy affects diabetes outcomes is inconsistent. The purpose of this meta-analysis was to quantitatively summarize the findings on the associations between health literacy and diabetes knowledge, self-care activities, and glycemic control as disease-related outcomes, with specific focus on the type of health literacy assessment.

DATA SOURCES

Nine databases (MEDLINE, CINAHL, Communication and Mass Media Complete, PsychInfo, PsychArticles, Psychology and Behavioral Sciences Collection, ERIC, Sociology, Embase) were searched for peer-reviewed original research articles published until 31 March 2018.

METHODS

Studies with type 1 and/or type 2 diabetes patients aged 18 or older, providing a calculable baseline effect size for functional health literacy and diabetes knowledge, self-care activities, or HbA1C were included.

RESULTS

The meta-analysis includes 61 studies with a total of 18,905 patients. The majority were conducted in the USA, on type 2 diabetes patients, and used the S-TOFHLA as a performance-based or the BHLS as a perception-based measure of functional health literacy. Meta-analytic results show that all three outcomes are related to health literacy. Diabetes knowledge was best predicted by performance-based health literacy measures, self-care by self-report measures, and glycemic control equally by both types of health literacy assessment.

DISCUSSION

Health literacy plays a substantial role in diabetes knowledge. Findings for the role of health literacy in self-care and glycemic control remain heterogeneous, partly due to the type of health literacy assessment (performance- vs. perception-based). This has implications for the use of health literacy measures in clinical settings and original research. This meta-analysis was limited to functional health literacy and, due to the paucity of studies, did not investigate the role of other dimensions including communicative and critical health literacy.

Health Literacy and self-care among visually impaired people with type 1 diabetes in Denmark

AIMS

The aim of this study was to investigate health literacy and self-care among visually impaired people with type 1 diabetes in Denmark.

METHODS

Survey data from 1425 Danes with type 1 diabetes were categorised in two groups according to visual status: visually impaired ( n = 38) and sighted ( n = 1387). Using the Health Literacy Questionnaire and the Summary of Diabetes Self-Care Activities Scale, health literacy and self-care activities were assessed. Visually impaired respondents were compared to sighted respondents using t-tests and chi-squared tests.

RESULTS

Visually impaired people were older, had higher diabetes duration and were more likely to live alone. Also they had a significant lower level of health literacy on two key dimensions of health literacy ('Ability to find good health information' and 'Understanding health information well enough to know what to do'), they monitored blood sugar less frequently than people that were sighted but had better self-care regarding feet examination.

CONCLUSIONS

Visually impaired people with type 1 diabetes are less able to find and understand health information than sighted people with type 1 diabetes. Our findings indicate need for interventions to promote better self-care and health literacy among visually impaired people with diabetes.

Prevalence of limited health literacy among patients with type 2 diabetes mellitus: A systematic review

BACKGROUND

Health literacy (HL) skills are essential to enable self-management and shared decision-making in patients with type 2 diabetes mellitus (T2DM). Limited HL in these patients is associated with poorer outcomes. It is not clear what the burden of limited HL in patients with T2DM across countries and what factors influence it.

METHODS

A systematic review was conducted according to the PRISMA guidelines. The study protocol was registered with PROSPERO (CRD42017056150). We searched MEDLINE, EMBASE, PsycINFO, CINAHL and ERIC for articles published up to January 2017. Articles that measured HL levels in adult patients with T2DM; that used validated HL tools; and that were reported in English were included. Two reviewers assessed studies for eligibility and quality, and extracted the data. Prevalence of limited HL is calculated from the number of patients with less than adequate HL over the total number of patients with T2DM in the study. Meta-analysis and meta-regression analysis were conducted using the Open Meta-analyst software.

RESULTS

Twenty-nine studies involving 13,457 patients with T2DM from seven countries were included. In total, seven different HL measurement tools were used. The prevalence of limited HL ranged from 7.3% to 82%, lowest in Switzerland and the highest in Taiwan. Meta-regression analysis of all included studies showed the country of study (p<0.001), HL tool used (p = 0.002), and the country's region (p<0.001) contributed to the variation findings. Thirteen studies in the USA measured functional HL. The pooled prevalence of inadequate functional HL among patients with T2DM in the USA was 28.9% (95% CI: 20.4-37.3), with high heterogeneity (I2 = 97.9%, p <0.001). Studies were done in the community as opposed to a hospital or primary care (p = 0.005) and populations with education level lower than high school education (p = 0.009) reported a higher prevalence of limited HL.

CONCLUSION

The prevalence of limited HL in patients with T2DM varied widely between countries, HL tools used and the country's region. Pooled prevalence showed nearly one in three patients with T2DM in the USA had limited functional HL. Interactions with healthcare providers and educational attainment were associated with reported of prevalence in the USA.

Factors Affecting Insulin Compliance in Patients with Type 2 Diabetes in South Iran, 2017: We Are Faced with Insulin Phobia

BACKGROUND

Many patients with type 2 diabetes are uncontrolled on maximum oral treatment. The early introduction of insulin can lower diabetes-related complications. This study aimed to evaluate type 2 diabetes patients' demographic characteristics, clinical factors, and attitude toward insulin therapy initiation.

METHODS

In the present cross-sectional study, 457 patients were selected from 12 diabetes clinics in the southern Iranian city of Shiraz in 2017. Adult patients (>30 y) with type 2 diabetes indicated to use insulin for the first time (insulin-naive) were asked to complete a researcher-designed questionnaire. The data were analyzed using SPSS 19. The relationships between insulin and the tendency to use insulin, demographic characteristics, and clinical data were evaluated using the χ² or t test and logistic regression. The significance level was considered at 0.05.

RESULTS

The mean age of the participants was 55.16±8.76 years and 67.4% were female. Despite physician recommendations, 60.2% of the patients were disinclined to use insulin. Those unwilling to initiate insulin therapy had more misconceptions. In the multivariate analysis, the chances of insulin noncompliance were increased by 4.63-fold among the patients without supplementary insurance (P<0.001), by 2.38-fold among those with a nondiabetic diet (P=0.002), and by 6.75-fold among the illiterate ones (P<0.001).

CONCLUSION

Based on the results, the factors affecting insulin noncompliance in our insulin-naive patients with type 2 diabetes included insurance coverage, illiteracy, and nondiabetic regimens as well as misconceptions about and irrational fear of insulin injection. Overall, our results indicate the need for further education and financial support for patients and health staff.

Adequate health literacy is associated with better health outcomes in people with type 2 diabetes in Mexico

This study evaluates the health literacy of people with type 2 diabetes and its association with health outcomes. We conducted a cross-sectional survey in two family medicine clinics of the Mexican Institute of Social Security that included 778 diabetic patients >19 years of age. The Spanish version of the European Health Literacy questionnaire served to measure health literacy. Multiple logistic regressions were performed to determine the association between the independent variable (health literacy) and dependent variables (good self-rated health, glycemic control, and diabetes-related hospitalizations) after controlling for conceptually relevant patient's characteristics. Only 17.6% of patients had adequate health literacy; while, the remaining percentage showed inadequate (23%), or problematic (59.4%) health literacy. After adjusting for the patients' characteristics, those with adequate health literacy had 4.66 (95%CI: 2.26-9.61) times the odds of good self-rated health compared to those with inadequate literacy. Patients with adequate health literacy had 0.65 (95%CI: 0.49-0.86) times the odds of hospitalization due to diabetes compared to those with inadequate literacy. Compared to inadequate health literacy, problematic literacy was associated with increased odds of glycemic control. In conclusion, healthcare providers should actively address the health literacy needs of patients to increase good self-rated health, glucose control and reduce hospitalizations.

Conhecimento sobre o diabetes e atitude para o autocuidado de idosos na atenção primária à saúde

Resumo Objetivou-se avaliar o conhecimento sobre o diabetes, a atitude para o autocuidado e os fatores associados, por meio de estudo transversal, na linha de base de um ensaio clínico randomizado, com idosos diabéticos na atenção primária de saúde do Recife, Nordeste do Brasil. Utilizou-se o Diabetes Knowledge Scale (DKN-A) e o Diabetes Attitudes Questionnaire (ATT-19). Dos 202 idosos, 77,7% apresentaram conhecimento insuficiente sobre a doença, com destaque para a cetonúria, substituição de alimentos e desconhecimento das causas e dos cuidados com a hipoglicemia. Quanto à atitude, 85,6% tiveram ajustamento psicológico negativo em relação ao diabetes. O modelo de regressão logística mostrou que morar sozinho foi fator de proteção (OR = 0,24; IC95% 00,9-0,65; OR = 0,22; IC95% 0,07-0,71) e baixa escolaridade fator de risco (OR = 7,78; IC95% 3,36-18,01; OR = 13,05; IC95% 4,63-36,82) para conhecimento insuficiente e atitude negativa para o autocuidado, respectivamente. Os achados reforçam a necessidade de ações educativas interdisciplinares que incluam aspectos socioeconômicos, psicoemocionais e educacionais na gestão do diabetes com vistas à manutenção da autonomia e funcionalidade do idoso.

Functional health literacy in hypertensive elders at primary health care

ABSTRACT Objective: to assess the relationship between inadequate functional health literacy and inadequate blood pressure control in older people with hypertension in Primary Health Care. Method: a cross-sectional study with sample calculated at 392. SAHLPA-18 tool was used for functional health literacy; blood pressure was measured; sociodemographic and clinical data were collected. Hierarchical logistic regression was used. Results: (high) inadequate blood pressure and (low) functional inadequate health literacy were present in 41.6% and 54.6% of the people, respectively. Factors associated with inadequate blood pressure were: inadequate functional health literacy, black-brown skin color, overweight-obesity, hypertension diagnosis time, non-adherence to exercise/diet, drug treatment. Schooling had no association with inadequate blood pressure Conclusion: hypertensive elderly people with inadequate health literacy were more likely to have inadequate blood pressure. Thus, health professionals need to value functional health literacy as a possible component to control blood pressure.

Using co-design to develop interventions to address health literacy needs in a hospitalised population

Background

Health literacy describes the cognitive and social skills which determine the motivation and ability of individuals to gain access to, understand and use information in ways which promote and maintain good health. Suboptimal health literacy is common and is believed to impact up to 60% of Australians. Co-design is a participatory approach to the development of interventions that brings together to staff and patients to design local solutions to local problems. The aim of this study is to describe a staff and patient co-design process that will lead to the development of health literacy interventions in response to identified health literacy needs of hospital patients.

Methods

A mixed methods, two-step sequential explanatory design. Step 1: hospitalised patients surveyed and data analysed using hierarchical cluster analysis to establish health literacy profiles. Step 2: clusters presented as vignettes to patients and clinicians to co-design interventions to address needs.

Results

Eight health literacy clusters were identified from surveys. Seven patients attended two patient workshops and 23 staff attended two staff workshops. Three key themes were identified: organisational, provider-patient, and patient self-care. Within these, five sub-themes emerged: “Good quality communication during hospital stay”, “Social support for health”, “A good discharge”, “Care across the continuum” and “Accessing quality information when home”. Fifteen potential interventions were produced, including changes to message design and delivery, staff training in assessing for understanding, social support to improve understanding, improving communication consistency across the care continuum, and strategic dissemination of web-based resources.

Conclusion

This study identified fifteen strategies to address health literacy needs of a hospital population. Implementation and evaluation will identify sets of strategies that have the maximum patient, clinician and organisational benefit. This approach allows for the development of locally-driven, contextually-appropriate interventions to address health literacy needs.

Addressing Clinical Inertia in Type 2 Diabetes Mellitus: A Review

The current epidemic of type 2 diabetes (T2D) represents a significant global and national health concern. Globally, the prevalence of diabetes has doubled between 1980 and 2014. In 2014 the World Health Organization estimated that there were 422 million adults living with diabetes worldwide. In the USA, the number of people diagnosed with T2D is estimated to increase to over 70 million by 2050, putting an immense strain on the US healthcare system. Achieving glycemic control is widely acknowledged as the key goal of treatment in T2D and is critical for reducing the onset and progression of diabetes-related complications such as cardiovascular diseases, neuropathies, retinopathies, and nephropathies. Despite the increase in the availability of antihyperglycemic medications and evidence-based treatment guidelines, the proportion of people with T2D who fail to achieve glycemic goals continues to rise. One major contributor is a delay in treatment intensification despite suboptimal glycemic control, referred to as clinical or therapeutic inertia. Clinical inertia prolongs the duration of patients' hyperglycemia which subsequently puts them at increased risk of diabetes-associated complications and reduced life expectancy. Clinical inertia results from a complex interaction between patient, healthcare providers, and healthcare system barriers that need to be addressed together, rather than as separate entities. In this article we provide an overview of clinical inertia in the clinical management of T2D and provide suggestions for overcoming aspects that may have a negative impact on patient care.Funding: Sanofi US, Inc.

Relationships between health literacy, motivation and diet and physical activity in people with type 2 diabetes participating in peer-led support groups

AIMS

To investigate associations between health literacy (HL) and diet and physical activity, and motivation and diet and physical activity in Danish people with type 2 diabetes.

METHODS

We used a cross-sectional design including 194 individuals with type 2 diabetes participating in peer-led support groups provided by the Danish Diabetes Association between January-December 2015. The participants completed a questionnaire at the first meeting including; The Summary of Diabetes Self-Care Activities (SDSCA) measure, The Treatment Self-Regulation Questionnaire (TSRQ) (Self-Determination Theory) measuring type of motivation, and two HL scales: The HLS-EU-Q16, and the Diabetes Health Literacy scale (Ishikawa, H). Data were analyzed using linear regression models adjusting for age, gender, educational level, diabetes duration, motivation and HL.

RESULTS

The adjusted β (95%CI) showed that autonomous motivation and functional HL were associated with following recommended diet: autonomous motivation; 0.43 (0.06; 0.80) and functional HL; 0.52 (0.02; 1.00). Autonomous motivation was related to following physical activity recommendations; β (95%CI) 0.56 (0.16; 0.96).

CONCLUSIONS

This study indicates that, for people with type 2 diabetes, functional HL and autonomous motivation may be important drivers for following diet recommendations, and autonomous motivation may be the most important factor for following recommendations regarding physical activity. These concepts may therefore be highly relevant to address in interventions to people with type 2 diabetes. Different interventions are suggested.

Health Literacy, Glycemic Control, and Physician-Advised Glucose Self-Monitoring Use in Type 2 Diabetes

Objective

To measure the association between health literacy and both patient-reported and clinical outcomes in patients with non-insulin-treated type 2 diabetes.

Research Design and Methods

We surveyed patients with non-insulin-treated type 2 diabetes (n = 448) from 15 primary care practices. The association between health literacy and patient-reported and clinical outcomes, including numeracy of self-monitoring of blood glucose (SMBG) use, how often physicians advised patients to conduct SMBG testing, and glycemic control (as measured by A1C), was investigated.

Results

Study participants included 448 patients with non-insulin-treated type 2 diabetes located within central North Carolina. Participants with limited health literacy had poorer glycemic control (A1C 7.7 ± 1.1% vs. 7.5 ± 1.0%, P = 0.016) despite using SMBG testing more frequently (daily SMBG testing 49.3 vs. 30.7%, P = 0.001) compared to individuals with adequate health literacy. The difference in how often physicians advised patients to conduct SMBG testing between limited and adequate health literacy groups was not significant (P = 0.68).

Conclusion

Limited health literacy was associated with poorer glycemic control and an increased frequency of SMBG testing in patients with non-insulin-treated type 2 diabetes. There was no significant difference in how often physicians advised patients to conduct SMBG testing between patients with limited and adequate health literacy.

Health literacy and current CD4 cell count in a multiethnic U.S. sample of adults living with HIV infection

Hispanic and Black adults are disproportionately affected by HIV and experience poorer HIV-related health outcomes relative to non-Hispanic White adults. The current study adopted Sørensen's integrated model to test the hypothesis that lower functional and critical health literacy competencies contribute to poorer HIV-related health and CD4 cell count for Hispanic and Black individuals. Eighty-one non-Hispanic White, Hispanic, and Black HIV seropositive individuals from a large, Southwestern metropolitan area were administered measures of health literacy, including the Expanded Numeracy Scale, Newest Vital Sign, Rapid Estimate of Adult Literacy in Medicine, Test of Functional Health Literacy (TOHFLA)-numeracy, and TOHFLA-reading. Hispanic and Black individuals demonstrated less HIV knowledge than non-Hispanic White individuals. Black participants demonstrated fewer health literacy appraisal skills. Importantly, lower levels of health literacy were linked to poorer CD4 cell count (an index of immune functioning) for Hispanic and Black individuals and not for non-Hispanic White individuals. These findings suggest race group differences for health literacy on current CD4 cell count such as very specific dimensions of low health literacy (e.g. poorer judgment of health-related information), but not other presumed deficits (e.g. motivation, access), play an important role in clinical health outcomes in HIV.

The effect of a health literacy approach to counselling on the lifestyle of women with gestational diabetes: A clinical trial

Background: Gestational diabetes is a common pregnancy disorder that affects the mother's and neonate's health. The present study was conducted to investigate the effect of a health literacy approach to counselling on the lifestyle of women with gestational diabetes. The present randomized controlled clinical trial was conducted in 2017 using a parallel design. The subjects included 84 eligible women presenting to Alborz and Kamali Hospitals, Karaj, Iran. Methods: Convenience sampling was first used to select the subjects. They were then assigned to an intervention or control group based on randomized blocks of four. Both groups attended counselling sessions. The mothers in the intervention group attended six sessions of counselling with a health literacy approach in addition to counselling on routine pregnancy care. The control group attended counselling sessions on safe pregnancy care and received a training package containing all the subjects discussed in the intervention group. The Lifestyle Questionnaire and the Iranian Health Literacy Questionnaire were completed by the mothers at the beginning and at the end of the sessions as well as three weeks after the sessions. The data obtained were analyzed in SPSS-19. Results: According to the study findings, the scores of lifestyle (P=0.8) and health literacy (P=0.423) showed no significant differences between the intervention and control groups before the intervention. Significant differences were, however, observed in the mean scores of lifestyle and health literacy between the two groups immediately and three weeks after the intervention. Comparing the means showed a higher increase in the mean scores in the intervention group (P<0.001). Conclusions: Providing counselling services by midwives can significantly help modify mothers' unhealthy lifestyle choices and increase their health literacy; therefore, reducing maternal and neonatal consequences, especially in high-risk pregnancies.

Differences in health literacy profiles of patients admitted to a public and a private hospital in Melbourne, Australia

BACKGROUND

Health literacy refers to an individual's ability to find, understand and use health information in order to promote and maintain health. An individual's health literacy may also be influenced by the way health care organisations deliver care. The aim of this study was to investigate the influence of hospital service type (public versus private) on individual health literacy.

METHODS

Two cross-sectional surveys were conducted using the Health Literacy Questionnaire (HLQ), a multi-dimensional self-report instrument covering nine health literacy domains. Recently discharged private patients (n = 3121) were sent the survey in English, public patients (n = 384) were sent the survey in English, Arabic, Chinese, Vietnamese, Italian or Greek. Eligibility included hospitalisation ≥24 h in last 30 days, aged ≥18 years, no cognitive impairment. Odds ratios were used to assess differences between hospital sociodemographic and health related variables. ANOVA and Cohen's effect sizes compared HLQ scores between hospitals. Chi square and multiple logistic regression were used to determine whether differences between private and public hospital HLQ scores was independent of hospital population sociodemographic differences. ANOVA was used to review associations between HLQ scores and subgroups of demographic, health behaviour and health conditions and these were then compared across the two hospital populations.

RESULTS

Public hospital participants scored lower than private hospital participants on eight of the nine health literacy domains of the HLQ (scores for Active Appraisal did not differ between the two samples). Six domains, five of which in part measure the impact of how care is delivered on health literacy, remained lower among public hospital participants after controlling for age, education, language and income. Across both hospital populations, participants who were smokers, those who had low physical activity, those with depression and/or anxiety and those with 3 or more chronic conditions reported lower scores on some HLQ domains.

CONCLUSIONS

Our finding of lower health literacy among patients who had received care at a public hospital in comparison to a private hospital, even after adjustment for sociodemographic and language differences, suggests that private hospitals may possess organisational attributes (environment, structure, values, practices and/or workforce competencies) that result in improved health literacy responsiveness.

The Relationship between Health Literacy and Health Promoting Behaviors in Patients with Type 2 Diabetes

BACKGROUND

Health promoting behaviors are known to be a key factor in managing type 2 diabetes and improving the quality of life in diabetic patients. However, there is little known about the factors influencing these behaviors in diabetic patients. This study aimed to find the relationship between the health literacy and health promoting behaviors in patients with type II diabetes.

METHODS

This correlational study was conducted from August to September 2016 on 175 eligible diabetic patients (20 to 65 year-old) who referred to the selected centers of diabetes control in Ahvaz City. Patients were chosen using convenience non-probable sampling. Data were collected by diabetic patients' health promoting behaviors' questionnaire and health literacy questionnaire. Data were analyzed using SPSS 22, descriptive statistics and Pearson's correlation coefficient.

RESULT

The mean scores for health promoting behaviors and health literacy were determined 100.45±19.82 and 76.14±15.26, respectively. The highest and lowest scores in health promoting behaviors belonged to nutrition (26.11±6.85) and physical activity (6.70±2.75), respectively. There was a significant relationship between all dimensions of health promoting behaviors and health literacy (P<0.05).

CONCLUSION

Since health literacy has a positive relationship with health promoting behaviors in diabetic patients, health care providers need to concentrate on increasing the health literacy of their patients rather than solely concentrating on increasing their knowledge, thereby facilitating the development of health promoting behaviors in patients.
