Abstract

Background: Health literacy is strongly associated with health inequality among persons with deafness, and hypertension (HTN) is the most prevalent chronic disease among persons with deafness in South Korea. Despite its importance, research regarding the health literacy levels of persons with deafness with HTN in South Korea is lacking. This study aimed to comprehensively assess the health literacy levels of persons with deafness with HTN in South Korea, including linguistic, functional, and internet health literacy.

Methods: In this descriptive cross-sectional study, 95 persons with deafness with HTN were recruited through facilities associated with the deaf community. From August 2022 to February 2023, data were collected through face-to-face surveys attended by a sign language interpreter and online surveys. The data were analyzed using descriptive statistics and Spearman's correlation.

Results: Approximately 62.1% of the participants exhibited a linguistic health literacy level corresponding to less than that of middle school students, and the total percentage correct of functional health literacy was 17.9%. Each domain of internet health literacy was low. Significant correlations were found between some aspects of health literacy.

Conclusions: The study's findings highlight the low health literacy levels across various facets among persons with deafness with HTN in South Korea. Based on these findings, several strategies are suggested for developing HTN self-management interventions for persons with deafness. This study contributes to the foundational understanding of health literacy among persons with deafness with HTN in South Korea and provides valuable insights and guidance for developing HTN self-management interventions.
