Theoretical framework of concerns about falling in older people: the role of health literacy

Association between mobility decline and health literacy in older Japanese adults: Onjuku study

Decline in mobility is a global issue that must be addressed in rapidly aging societies. We aimed to clarify the association between locomotive syndrome (LS), a condition of decreased mobility and health literacy (HL) in community-dwelling Japanese adults aged ≥ 40 years. A descriptive survey was conducted in Onjuku Town, Japan, between 2019 and 2023. The participants performed LS risk tests, including the two-step test, stand-up tests and 25-question geriatric locomotive function scale, to assess mobility. They completed the 14-item health literacy scale to quantify the total HL and functional, communicative and critical HL subscales. Other participant characteristics, such as chronic diseases, bodily pain and physical activity, were also surveyed. The association between LS and HL was assessed using univariate and multivariate logistic regression analyses, adjusted for participant characteristics. We analyzed 492 participants with a median age of 71 years. The total HL score decreased as the LS stage increased, with 56, 54 and 51 points in stages 0, 1 and ≥ 2, respectively (p = 0.004). In the logistic regression analysis, a high total HL score was significantly associated with reduced odds of stage ≥ 2 LS (adjusted odds ratio, 0.95; p < 0.001). Furthermore, functional HL score had an independent association with stage ≥ 2 LS (adjusted odds ratio, 0.88; p = 0.009). Our results suggest that clinicians should provide HL education in addition to known preventive measures, such as promoting physical activity, as a holistic approach to decreased mobility.

Health Literacy in Fall-Prevention Strategy: A Scoping Review

PURPOSE

Although the significance of health literacy (HL) in fall-prevention strategies is growing, limited knowledge is available regarding the relationship, impact, and role of HL in falls. This scoping review aimed to explore and synthesize the current evidence regarding the role of HL in enhancing fall prevention in hospital and community settings.

METHODS

We adhered to the Joanna Briggs Institute manual and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews. PubMed, CINAHL, EMBASE, and the Cochrane Library were searched until November 2023 using Medical Subject Headings and text words. Studies related to HL and falls, regardless of study design, were considered eligible.

RESULTS

We screened 99,249 records, of which 27 were included: 12 interventional studies, seven observational studies, four qualitative studies, and four mixed-methods studies. Two-thirds of the studies were conducted in community-based settings. Four observational studies reported that HL was associated with fall-related outcome including fall incidence. Although intervention studies did not encompass all elements of HL based on the Health Literacy Framework, eight out of 12 intervention studies reported the effect of HL-embedded fall-prevention interventions, and HL was effective in fall-related outcomes including fall incidence in six studies. Three of 14 studies reported the measurement properties of fall-related HL. While HL can be increased through tailored information, verbal debriefing, interactive communication, and culturally adapted interventions, low HL impedes the understanding of education, engaging interventions, and using technological devices in implementing fall-prevention interventions in qualitative and mixed-methods studies.

CONCLUSION

This scoping review suggests that nurses need to recognize and assess patients' HL as a potential risk factor for falls and implement fall-prevention interventions based on the HL level of participants. Further research is required to develop culturally adapted and fall-relevant HL measures applicable to various vulnerable populations and settings.

Health literacy and falls among community-dwelling older people in China: is there a sex difference?

BACKGROUND

Health literacy is one of the important determinants of healthy aging, yet few studies have focused on the association between health literacy and falls.

AIMS

This study aims to explore the relationship between health literacy and falls, with a focus on sex differences among older people in China.

METHODS

This cross-sectional study enrolled 2,144 older people aged ≥ 60 years from Shandong Province, China in 2021. We used general health literacy screening scale to assess health literacy, and collected the incidence of falls in the past year. Logistic regression models were employed to analyze the relationship between health literacy and falls. We investigated the sex differences by subgroup analyses.

RESULTS

The prevalence of adequate health literacy and falls was 21.7% (95% CI: 20.0-23.5%) and 25.4% (95% CI: 23.6-27.3%), respectively. In a fully-adjusted model, adequate health literacy was associated with a lower prevalence of falls in older adults (OR = 0.71, 95%CI: 0.52-0.96). Subgroup analysis revealed sex differences in this relationship (Pfor interaction <0.05). Specifically, the female group showed no significant relationship between health literacy and falls (OR = 0.92, 95% CI: 0.59-1.44); however, the male group demonstrated a robust and significant relationship (OR = 0.58, 95% CI: 0.37-0.90).

CONCLUSIONS

Older people with adequate health literacy have lower prevalence of falls, which appears to differ by sex. This relationship was significant among men but not among women. These findings emphasize the need for policymakers and healthcare providers to consider sex differences when designing and implementing programs aimed at improving health literacy and preventing falls in the older population. Improving health literacy among older women could be a strategic component in bridging sex inequality in falls.
