Health literacy and quality of life in Iranian persons with COPD

Background: Chronic obstructive pulmonary disease is a progressive disorder with significant physical, psychological, and social consequences and adversely affects the persons' quality of life (QOL). Objectives: This study aimed to determine the health literacy (HL) and QOL of persons with COPD and some of the contributing factors. Methods: A cross-sectional study was conducted from May to December 2019 on 270 persons with COPD referring to Shahid-Beheshti Hospital of Kashan, Iran. Data were collected using a demographic questionnaire, the 33-item Health Literacy Questionnaire of the Urban Population of Iran (with a total score ranging from 33 to 165, higher score indicates higher HL) and the 50-item St. George's Respiratory Questionnaire for assessing the QOL (with a total score ranging from zero to 100, greater score means lower QOL). Descriptive statistics, Pearson and Spearman correlation coefficient, Chi-square test, t-test, analysis of variance, and linear regression analysis were used to analyze the data. Results: The mean age and the mean duration of COPD were 59.48 +/- 13.31 and 3.85 +/- 3.47 years, respectively. The mean HL score and the mean QOL were 81.44 +/- 23.89 and 57.41 +/- 10.70, respectively. A significant correlation was found between HL and QOL (r=-0.21, p <0 .001). Conclusion: Participants had moderate levels of HL and QOL. There was a significant correlation between HL and QOL. Health care providers are recommended to take effective steps to improve the HL of persons with COPD by developing comprehensive educational programs for them. (C) 2022 Elsevier Inc.
