Abstract

Background

Stroke may cause debilitating neurological deficiencies that result in motor, sensory, and cognitive deficits and poorer psychosocial functioning. Prior studies have provided some initial evidence for the significant roles of health literacy and poor oral health for old people. However, few studies have focused on the health literacy of individuals who had a stroke; therefore, the relationships between the health literacy and oral health-related quality of life (OHRQoL) among middle-aged and older adults who had a stroke are unknown. We aimed to assess the relationships between stroke prevalence, health literacy status, and OHRQoL in middle-aged and older adults.

Methods

We retrieved the data from The Taiwan Longitudinal Study on Aging, a population-based survey. For each eligible subject, we gathered data in 2015 on age, sex, level of education, marital status, health literacy, the activity daily living (ADL), stroke history and OHRQoL. We evaluated the respondents’ health literacy by using a nine-item health literacy scale and categorized their health literacy level as low, medium, or high. OHRQoL was identified based on the Taiwan version of the Oral Health Impact Profile (OHIP-7T).

Results

The final study contained 7702 community-based dwelling elderly people (3630 male and 4072 female) were analysis in our study. Stroke history was reported in 4.3% of participants, 25.3% reported low health literacy, and 41.9% had at least one ADL disability. Furthermore, 11.3% of participants had depression, 8.3% had cognitive impairment, and 3.4% had poor OHRQoL. Age, health literacy, ADL disability, stroke history, and depression status were significantly associated with poor OHRQoL after sex and marital status was adjusted. Medium (odds ratio [OR] = 1.784, 95% confidence interval [CI] = 1.177, 2.702) to low health literacy (OR = 2.496, 95% CI = 1.628, 3.828) was significantly associated with poor OHRQoL.

Conclusions

Base our study results, people with stroke history had poor OHRQoL. Lower health literacy and ADL disability were associated with worse QHRQoL. Further studies are necessary to define practical strategies for reducing the risk of stroke and oral health with constantly lower health literacy, thereby improving the quality of life and providing health care of older people.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
