Limited health literacy increases the risk of frailty among community-dwelling older adults: Longitudinal findings from the Korean Frailty and Aging Cohort Study

Mediating role of health literacy in relationship between frailty and health-related quality of life in community-dwelling older adults

PURPOSE

The aim of this study was to investigate the mediating effects of health literacy on the relationship between frailty and health-related quality of life (HRQOL) among community-dwelling older adults.

METHODS

This study used the Korean Frailty and Aging Cohort Database (KFACD) for secondary data analysis. We selected data from 1,631 people without missing main variable values for analysis. Frailty was determined based on the modified Fried's phenotype [MFP], and HRQOL was measured using the Korean version of the 5-level EuroQol questionnaire (EQ-5D-5L). Health literacy was assessed using the questions on the Behavioral Risk Factor Surveillance System (BRFSS) used by the U.S. Center for Disease Control and Prevention. To examine the mediating role of health literacy in the relationship between frailty and HRQOL, Baron & Kenny's three-step mediating effect verification method was utilized.

RESULTS

The participants had a mean frailty score of 1.37±1.02, health literacy score of 8.56±2.59, and HRQOL score of 0.84±0.10. Frailty was negatively correlated with health literacy (r = -0.27, p < .001) and HRQOL (r = -0.32, p < .001), while health literacy was positively correlated with HRQOL (r = 0.34, p < .001). We observed that health literacy played a partial mediating role in the relationship between frailty and HRQOL.

CONCLUSION

To increase older adults' HRQOL, measures that directly prevent and manage frailty as well as interventions that target the enhancement of health literacy are needed.

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.

Protocols and Features of Goal-Setting-Based Intervention for Frail Older Adults in Community Exercise Facilities

Appropriate goal setting for frail older adults is important because it drives effective rehabilitation. However, more insights into the types and degrees of frailty and goal-setting trends should be obtained. We conducted a multicenter prospective study to qualitatively examine the relation between each frailty domain (physical, social, and cognitive) and the goals of 201 subjects (median age: 79, 43.8% male) who began rehabilitation at a long-term care prevention facility. Goal setting was determined by the specific, measurable, achievable, relevant, and time to goal (SMART) framework up to three months, categorized according to the International Classification of Functioning, Disability, and Health. The results showed that approximately 90% of the subjects had frailty in at least one domain, and about half had frailties in two or more domains. In total, 176 (87.6%) subjects had goals corresponding to activities and participation. The tendency to set goals to improve mobility was confirmed when the number of overlapping frailties was high, especially those in the physical and social domains. Those with milder frailties were more likely to establish goals targeting improvements in community, social, and civic life. These findings will lead to the development of practical goal-setting guidelines for frail older adults.
