Associations between working memory, health literacy, and recall of the signs of stroke among older adults

Patterns of health literacy and influencing factors differ by age: a cross-sectional study

BACKGROUND

Individuals with better health literacy communicate more effectively with healthcare providers, adhere better to medical instructions, and manage their health more successfully. While interest in health literacy is increasing, there is still a lack of comprehensive analysis that includes all age groups. In this study, we examine differences in health literacy and in health literacy-related factors between the elderly and other age groups.

METHODS

This study used data from the 2020-2021 Korea Health Panel and the 2021 health literacy supplementary survey. The survey included 7,910 participants aged 19 and older and employed the HLS-EU-Q16 tool to measure health literacy. Sociodemographic, health behavior, and healthcare utilization variables were analyzed. Statistical analyses, including chi-square tests, t-tests, and multiple regression analyses, explored the relationships between health literacy and factors influencing it across different age groups.

RESULTS

Health literacy scores decreased with age, with the average score for all participants being 10.96. Specifically, the young group scored higher (14.10), the middle-aged group scored moderately (12.43), and the older group scored the lowest (8.34). We identified several factors influencing health literacy that were consistently significant across age groups, including education, income, self-rated health, and quality of life. Notably, in the elderly group, health-promoting behaviors like walking were associated with health literacy, and those with low education or chronic diseases faced the most significant challenges in health literacy.

CONCLUSIONS

We found that health literacy declined significantly as adults grew older. In addition, factors related to health literacy differed by age group. These results highlight the need for tailored interventions to meet the specific needs of each age group.

Health literacy in stroke disease: A systematic review

BACKGROUND

Health literacy has been demonstrated to be a factor that influences patients' ability to retain clinical education and counselling.

AIMS

To describe: (1) the importance of health literacy in the prevention of stroke; (2) the correlation of risk factors with health literacy; and (3) the importance of health literacy in post-stroke outcomes.

METHODS

A systematic review was conducted using the following databases: PubMed (via Medline), CINAHL (via EBSCO), PsycINFO (via EBSCO), and Web of Science (via EBSCO) for studies focused on health literacy in stroke. We included qualitative, quantitative and observational studies. The critical appraisal tool of JBI-Checklists was used to assess the methodological quality of the included studies.

RESULTS

Thirty-three studies, involving 35,935 participants, were selected for this systematic review. Most of the studies (41 %) were cross-sectional. Health literacy levels among the general population and stroke patients were found to be relatively low, indicating the need for increased stroke education. Hypertension and stress were the most frequently identified risk factors while pregnancy and oral contraceptives, and anticoagulants were the least. People at risk of stroke have indicated a desire for more practical information and individually tailored behavioral interventions.

CONCLUSIONS

The results of this study highlighted the deficiency in health literacy among different populations. We noticed that even a simple educational intervention can help to improve health literacy. Targeting the general public is important in order to rapidly translate knowledge into action and to reduce the time from symptom onset to hospital arrival as time plays an important role in stroke.

Health literacy is associated with cognition and everyday functioning in a consecutive clinical series of people with epilepsy in a surgical setting

OBJECTIVE

Low health literacy is common among people with epilepsy (PWE) and may play an important role in disease management and outcomes. The current study evaluated whether health literacy is related to cognition, health, and everyday functioning in PWE.

METHODS

This cross-sectional, correlational study included 25 demographically comparable healthy adults retrospectively matched to a consecutive series of 89 PWE presenting for neuropsychological evaluation in a surgical setting and who completed the Newest Vital Sign and Brief Health Literacy Screener. The PWE also completed a comprehensive neuropsychological battery and measures of quality of life and everyday functioning.

RESULTS

PWE had significantly lower health literacy as compared to healthy adults (ps < 0.05) at a medium-to-large effect size. In analyses covarying for education and oral word reading literacy in the PWE sample, lower health literacy was independently associated with bilateral seizure onsets, greater antiseizure medication burden, poorer performance on measures of memory and information processing speed, and difficulties with self-care (ps < 0.05).

SIGNIFICANCE

Findings suggest that PWE are at risk for low health literacy, which may be partly attributable to disrupted brain-behavior relationships and contribute to poorer everyday functioning. Future studies are needed to identify effective methods to support and improve health literacy in PWE.

Readability of patient education material in stroke: a systematic literature review

BACKGROUND

Stroke education materials are crucial for the recovery of stroke patients, but their effectiveness depends on their readability. The American Medical Association (AMA) recommends patient education materials be written at a sixth-grade level. Studies show existing paper and online materials exceed patients' reading levels and undermine their health literacy. Low health literacy among stroke patients is associated with worse health outcomes and decreased efficacy of stroke rehabilitation.

OBJECTIVE

We reviewed the readability of paper (i.e brochures, factsheets, posters) and online (i.e American Stroke Association, Google, Yahoo!) stroke patient education materials, reading level of stroke patients, accessibility of online health information, patients' perceptions on gaps in stroke information, and provided recommendations for improving readability.

METHOD

A PRISMA-guided systematic literature review was conducted using PUBMED, Google Scholar, and EbscoHost databases and "stroke", "readability of stroke patient education", and "stroke readability" search terms to discover English-language articles. A total of 12 articles were reviewed.

RESULTS

SMOG scores for paper and online material ranged from 11.0 - 12.0 grade level and 7.8 - 13.95 grade level respectively. Reading level of stroke patients ranged from 3rd grade to 9th grade level or above. Accessibility of online stroke information was high. Structured patient interviews illustrated gaps in patient education materials and difficulty with comprehension.

CONCLUSION

Paper and online patient education materials exceed the reading level of stroke patients and the AMA recommended 6th grade level. Due to limitations in readability, stroke patients are not being adequately educated about their condition.

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.

Feasibility of a telephone-delivered educational intervention for knowledge transfer of COVID-19-related information to older adults in Hong Kong: a pre-post-pilot study

Background

During the COVID-19 pandemic, educational interventions have become necessary to prevent the spread of health-related misinformation among Hong Kong older adults. The primary objective of this study was to assess the feasibility of a student-led, telephone-delivered intervention to improve COVID-19-related health knowledge among Hong Kong older adults. The secondary objective was to evaluate the impact of the intervention on the student volunteers.

Methods

Twenty-five participants aged 65 or above who were able to communicate in Cantonese and had no hearing or cognitive impairments were recruited for this longitudinal pre–post-study from a community center in Hong Kong. The pilot telephone-delivered intervention consisted of five telephone call sessions conducted by 25 student volunteers. Each participant was paired with the same volunteer throughout the intervention. The first four sessions included pre-tests that assessed the participants’ understanding of three COVID-19-related themes: medication safety, healthcare voucher scheme, and COVID-19 myth-busting. Standardized explanations of the pre-test questions were offered to participants during the phone calls. In the last session, a post-test on all the themes was conducted. The intervention’s feasibility was assessed based on (a) percentage changes in the participants’ test scores, (b) attrition rate, and (c) the acceptability of the intervention by the participants. The impact of the intervention on the student volunteers was evaluated based on a student feedback survey. There was no control group.

Results

Significant improvements in the participants’ test scores (out of 100%) for all themes were observed after the intervention: from 76 to 95.2% for medication safety, from 64.0 to 88.8% for the healthcare voucher scheme, and from 78.0 to 93.2% for COVID-19 myth-busting. The average improvement in test scores of the three themes was 18.4% (95% CI 12.2 to 24.6%). Most participants were satisfied with the program. The student feedback survey suggested that the intervention enhanced students’ communication skills and understanding of Hong Kong older adults.

Conclusion

This pilot study offers initial evidence of the potential and feasibility of student-led, telephone-delivered educational interventions for the transfer of COVID-19-related knowledge to older adults and their benefits for the student volunteers. Future studies should include larger samples and a control group.

The Level of Health Literacy of Seniors Living in Eastern Region of Poland. Preliminary Study

Health literacy (HL) is recognised as an important, modifiable factor in the self-management and health performance of elderly people. The aim of this preliminary study was to identify and analyse the level of health literacy among the elderly living in one of the eastern regions in Poland. The cross-sectional study was conducted among a convenience sample of 200 seniors aged 65+ after cognitive pre-screening with the use of the Montreal Cognitive Assessment (MoCA) scale. To collect data, the Polish version of the HLS-EU-Q47 was used. More than half of the elderly surveyed presented problematic levels of general HL (GEN-HL), and also problematic levels of other dimensions: health care health literacy (HC-HL), disease prevention health literacy (DP-HL), and health promotion health literacy (HP-HL). The level of seniors' HL is dependent on the level of their education, place of living, participation in activities run by Daily Center for the Elderly, and their self-assessment of health condition (p < 0.05). These results imply the important message that there is a need to create initiatives and programs improving health literacy targeted at seniors living in rural areas, those with lower levels of education, and those with poor access to activities organised by institutions supporting seniors.

Sex Differences in Prehospital Delay in Patients With Acute Stroke: A Systematic Review

BACKGROUND

In 2009, the window from symptom onset to administration of tissue plasminogen activator for acute ischemic stroke was extended from 3 to 4.5 hours. Yet no systematic review has addressed prehospital delay by sex for stroke symptoms since this change.

PURPOSE

We aimed to (1) compare prehospital delay times-the time from symptom onset to hospital arrival-between women and men with acute stroke or transient ischemic attack and (2) summarize factors influencing prehospital delay by sex.

METHODS

The CINAHL, MEDLINE, PubMed, Scopus, and PsycINFO databases were searched using PRISMA guidelines. Inclusion criteria were as follows: (1) quantitative research articles published between May 2008 and April 2019, (2) investigation of prehospital delay among women and men 15 years or older who were given a diagnosis of acute stroke or transient ischemic attack, and (3) English-language publications. The Crowe Critical Appraisal Tool was used to evaluate the quality of studies.

RESULTS

Fifteen publications (n = 162 856) met inclusion criteria. Most studies (n = 11) showed no sex differences in prehospital delay. Four studies from Asian-Pacific countries and the United States showed that women had significantly longer prehospital delay compared with men. Older age, minority race/ethnicity (black and Mexican American), and underuse of emergency medical services were associated with prolonged prehospital delay in women.

CONCLUSIONS

Most study authors found no differences in prehospital delay between women and men; however, women delayed longer in some Asian-Pacific and American studies. Findings of sex differences were inconclusive.

Cognitive abilities predict death during the next 15 years in older Japanese adults

AIM

The longitudinal relationship between cognitive abilities and subsequent death was investigated among community-dwelling older Japanese adults.

METHODS

Participants (n = 1060; age range 60-79 years) comprised the first-wave participants of the National Institute for Longevity Sciences-Longitudinal Study of Aging. Participants' cognitive abilities were measured at baseline using the Japanese Wechsler Adult Intelligence Scale-Revised Short Form, which includes the following tests: Information (general knowledge), Similarities (logical abstract thinking), Picture Completion (visual perception and long-term visual memory) and Digit Symbol (information processing speed). By each cognitive test score, participants were classified into three groups: the high-level group (≥ the mean + 1SD), the low-level group (≤ the mean - 1SD) and the middle-level group. Data on death and moving during the subsequent 15 years were collected and analyzed using the multiple Cox proportional hazard model adjusted for physical and psychosocial covariates.

RESULTS

During the follow-up period, 308 participants (29.06%) had died and 93 participants (8.77%) had moved. In the Similarities test, adjusted hazard ratios (HR) of the low-level group to the high-level group were significant (HR 1.49, 95% CI 1.02-2.17, P = 0.038). Furthermore, in the Digit symbol test, the adjusted HR of the low-level group to the high-level group was significant (HR 1.62, 95% CI 1.03-2.58, P = 0.038). Significant adjusted HR were not observed for the Information or Picture Completion tests.

CONCLUSIONS

It is suggested that a lower level of logical abstract thinking and slower information processing speed are associated with shorter survival among older Japanese adults. Geriatr Gerontol Int 2017; 17: 1654-1660.

Health Literacy and Older Adults: A Systematic Review

Objective: The objective of this review was to assess published literature relating to health literacy and older adults. Method: The current review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses. Results: Eight articles met inclusion criteria. All studies were conducted in urban settings in the United States. Study sample size ranged from 33 to 3,000 participants. Two studies evaluated health-related outcomes and reported significant associations between low health literacy and poorer health outcomes. Two other studies investigated the impact of health literacy on medication management, reporting mixed findings. Discussion: The findings of this review highlight the importance of working to improve health care strategies for older adults with low health literacy and highlight the need for a standardized and validated clinical health literacy screening tool for older adults.

Health literacy in Beijing: an assessment of adults' knowledge and skills regarding communicable diseases

BACKGROUND

There have been a number of studies conducted to date looking at the issue of health literacy, but none have been conducted in Beijing, China. The aim of this study was to evaluate the communicable diseases health literacy (CDHL) levels of Beijing residents towards three key areas: knowledge, adoption of preventative measures/behaviours, and health skills.

METHODS

A structured survey was undertaken with Beijing residents aged ≥18 years. A multistage stratified sampling approach was used to identify and recruit residents. Participants were excluded if they were foreigners, residents of Hong Kong, Macau or Taiwan, or were unable to communicate in Mandarin.

RESULTS

The questionnaire was completed by 11052 participants, with a moderate accuracy rate (average: 61.3 %) and a good discrimination level (average: 0.428). Cronbach's alpha was 0.748. The items were grouped into three subscales representing knowledge, adoption of preventative measures and behaviours, and health skills. Correlations of the subscales and the Total Score is significant (P < 0.01), and all the three subscales correlate strongly with the Total Score The mean CDHL score of Beijing inhabitants was 15.28. The percentage of those who were identified as having adequate CDHL was 41 %.

CONCLUSIONS

The total CDHL level of residents in Beijing was relatively low, particularly in those residing in the suburbs, those above 60 years of age, manual workers, and the illiterates. Gender, age-group, level of education, occupation, self-reported health status and region were all shown to be significantly predictive of CDHL. It is important that more resources are dedicated to improving the CDHL in Beijing, given the risk of emerging and re-emerging infectious diseases in the region.

Assessing the impact of health literacy on education retention of stroke patients

INTRODUCTION

Inadequate health literacy is a pervasive problem with major implications for reduced health status and health disparities. Despite the role of focused education in both primary and secondary prevention of stroke, the effect of health literacy on stroke education retention has not been reported. We examined the relationship of health literacy to the retention of knowledge after recommended stroke education.

METHODS

This prospective cross-sectional study was conducted at an urban safety-net hospital. Study subjects were patients older than 18 admitted to the hospital stroke unit with a diagnosis of acute ischemic stroke who were able to provide informed consent to participate (N = 100). Health literacy levels were measured by using the short form of Test of Functional Health Literacy in Adults. Patient education was provided to patients at an inpatient stroke unit by using standardized protocols, in compliance with Joint Commission specifications. The education outcomes for poststroke care education, knowledge retention, was assessed for each subject. The effect of health literacy on the Stroke Patient Education Retention scores was assessed by using univariate and multivariate analyses.

RESULTS

Of the 100 participating patients, 59% had inadequate to marginal health literacy. Stroke patients who had marginal health literacy (mean score, 7.45; standard deviation [SD], 1.9) or adequate health literacy (mean score, 7.31; SD, 1.76) had statistically higher education outcome scores than those identified as having inadequate health literacy (mean score, 5.58; SD, 2.06). Results from multivariate analysis indicated that adequate health literacy was most predictive of education outcome retention.

CONCLUSIONS

This study demonstrated a clear relationship between health literacy and stroke education outcomes. Studies are needed to better understand the relationship of health literacy to key educational outcomes for primary or secondary prevention of stroke and to refine stroke education for literacy levels of high-risk populations.
