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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

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.

Literacy in health and self-care in people with type 2 diabetes mellitus

ABSTRACT Objective: To evaluate the effect of educational intervention in the adherence to self-care activities and functional health literacy and numeracy in people with type 2 diabetes mellitus. Methods: This was a quasi-experimental study conducted in two units of the Brazilian Family Health Strategy, involving people with diabetes. Educational interventions occurred in three meetings, weekly, lasting 60 minutes on average. Data were collected using the Questionário de Autocuidado com o Diabetes, before and after the interventions. Results: 55 people participated in the study. After the interventions, the greatest difference for a better adherence to self-care was the item “inspecting the inside of the shoes before putting them on”, with 3.29 days in the week delta at analytical level. The worst was “taking insulin shots as recommended”, with 0.00 days a week delta at basic level. Conclusion: Educational interventions had a positive effect on adherence to self-care and functional literacy in health.

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.
