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.

Examining the relationship between health literacy and quality of life: evidence from older people admitted to the hospital

INTRODUCTION

Literacy has become an increasingly serious problem, especially as it relates to health care. In this regard, health literacy (HL), as a cognitive skill, has proven to be an influential factor to improve of the quality of life (QOL). This study aimed to examine the level of HL and its relationship with the QOL of older people at the time of discharge from the hospital in the south of Iran.

METHODS

This descriptive-analytical cross-sectional study included 300 older people admitted and treated in 10 teaching-therapeutic hospitals affiliated with the Shiraz University of Medical Sciences in 2021. The standard Health Literacy for Iranian Adults (HELIA) questionnaire and the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF) were used to collect the required data. Data were analyzed with SPSS software version 23 software using descriptive and inferential statistics, Pearson's correlation coefficient, T-test, ANOVA, and multiple linear regression at p = 0.05.

RESULTS

The mean scores of Hl and QOL for older people were 48.22 ± 9.63 (out of 100) and 61.59 ± 12.43 (out of 120), respectively. Moreover, there was a significant direct correlation between the participants' HL and their QOL (r=0.388, p<0.001). All dimensions of HL, including comprehension (β=0.461, p<0.001), decision-making and behavior (β=0.434, p<0.001), access (β=0.397, p<0.001), reading skill (β=0.362, p=0.002), and assessment (β=0.278, p=0.004), were significant relationship with QOL. A statistically significant difference was revealed between the mean scores of HL regarding the participants' gender (p=0.04) and level of education (p=0.001). Furthermore, the mean scores of QOL were significantly different with regard to older people's gender (p=0.02), marital status (p=0.03), level of education (p=0.002), and income (p=0.01).

CONCLUSION

The findings revealed the participants' inadequate HL and average QOL. Considering the relationship of HL with QOL, it is recommended to develop comprehensive programs and effective interventions to develop HL skills and subsequently improve QOL among older people.

Hospital health literacy conceptual explanation: A qualitative content analysis based on experts and population perspectives

BACKGROUND AND AIM

Given the complexities of the health care system and the importance of the subject and effects of health literacy in all aspects of care, defining specific health literacy in this context seems necessary. The purpose of this research was to explain the concept of hospital health literacy (HHL), its definition, and the related dimensions using the qualitative research method.

MATERIALS AND METHODS

An exploratory qualitative design was used. Exploratory, open-ended, and face-to-face interviews based on the interview guide were used to elicit participants' perspectives between July 2021 and January 2022. By using the content analysis method, researchers coded transcripts and collated these codes into sub-categories and then merged them into the main category and explored the dimensions of the concept.

RESULTS

A total of 23 service providers and 25 service recipients were included in the study. Analysis of qualitative data led to the identification of 6 categories and 25 sub-categories including cognitive literacy, functional (basic) literacy, communicative literacy, behavioral literacy, media literacy, and emotional literacy.

CONCLUSION

The findings of the present study provide a deep understanding of the concept of HHL that could be applied to develop valid and reliable measurement tools for assessing HHL among a variety of populations. Also, it is hoped that the present attempt can be useful to guide future research and interventions as well as to provide a clear base for planning, implementing, and evaluating interventions aimed at promoting individuals' health literacy in health settings.

Associations of Health Literacy with Blood Pressure and Dietary Salt Intake among Adults: A Systematic Review

Health literacy has been recognized as a significant social determinant of health, defined as the ability to access, understand, appraise, and apply health-related information across healthcare, disease prevention, and health promotion. This systematic review aims to understand the relationship between health literacy, blood pressure, and dietary salt intake. A web-based search of PubMed, Web of Science, CINAHL, ProQuest, Scopus, Cochrane Library, and Prospero was performed using specified search/MESH terms and keywords. Two reviewers independently performed the data extraction and analysis, cross-checked, reviewed, and resolved any discrepancies by the third reviewer. Twenty out of twenty-two studies met the inclusion criteria and were rated as good quality papers and used in the final analysis. Higher health literacy had shown to have better blood pressure or hypertension knowledge. However, the relationship between health literacy with dietary salt intake has shown mixed and inconsistent findings. Studies looking into the main four domains of health literacy are still limited. More research exploring the links between health literacy, blood pressure, and dietary salt intake in the community is warranted. Using appropriate and consistent health literacy tools to evaluate the effectiveness of salt reduction as health promotion programs is required.

Hipertensión arterial autorreferida en adultos mayores brasileños: uso de medicación y recomendaciones para el control

Objetivo Estimar la prevalencia de hipertensión arterial (HA) autorreferida y del uso de medicación en los adultos mayores brasileños (≥65 años), según las características sociodemográficas, y evaluar el uso de los servicios de salud y de las recomendaciones de los médicos y profesionales de salud para el control de la enfermedad.

Health literacy as a determinant of childhood and adult obesity: a systematic review

OBJECTIVES

To assess whether Health Literacy (HL) acts as a determinant of obesity in adults and children by synthesizing the results of recent scientific evidence.

CONTENT

This is a systematic qualitative review following the MOOSE guidelines. A systematic, computer-assisted literature search via PubMed scientific database, between January 1st, 2000, and September 30th 2020, was conducted. Only cross-sectional epidemiologic research studies that were published in the English language, investigating HL's possible role as a determinant of childhood and adult obesity, were included.

SUMMARY

After screening 725 citations from the PubMed database, 39 (n=39) studies in total were included in this literature review; Four (n=4) studies were conducted in the children population, seven (n=7) studies were performed in children-parent/caregiver dyads, and 28 studies (n=28) enrolled adults. There is significant evidence that HL knowledge and skills determine the consequent management of obesity and BMI rates in children and adult populations.

OUTLOOK

Despite policies and action plans put in place by countries globally, overweight and obesity continue to be a pressing public health issue and one of the critical drivers of non-communicable diseases, constituting a health, social and economic burden worldwide. Health Literacy as an essential health policy and promotion agenda item and a critical empowerment strategy could increase children's and adults' control over their overall health and awareness to overcome obesity issues. Initiatives to improve HL levels could be useful tools in managing the obesity epidemic, starting from integrating HL in the school curriculum and further in family and community action plans.
