Abstract
BackgroundRegarding the importance of health literacy as a key factor in self-care, appropriate understanding of health information by patients with type 2 diabetes mellitus (T2DM) is fundamental for better management of risk factors, which can also benefit their quality of life. This study aimed to describe the relationship between health literacy (HL), and self-care behaviors with health-related quality of life (HRQL) in patients with T2DM.MethodsA cross-sectional survey was done in Iran in 2019. Patients were recruited randomly from health centers by medical records (n = 192, 55.2% male, mean age 58.12 years). The data collection included demographic form, health literacy questionnaire, diabetes self-care behavior questionnaire, and world health organization’s Quality of Life-BREF (WHOQOL-BREF). Analyses were adjusted for confounders using hierarchical regression analysis.ResultsHL as predictor variables explained 47.5% of variance in overall HRQL (p value < 0.001), reading health information was the strongest HL dimension (β = 0.478). Self-care behaviors explained an additional 13.6% of the HRQL variance. In total, 65.5% of the variation in the HRQL is explained by the HL, self-care behavior, and the demographic variables.ConclusionWe found that more almost two-third of the HRQL explained by the HL and self-care behaviors. Given the importance of health literacy and self-care behaviors in the quality of life in patients with T2DM, adoption of health-promoting behaviors and increasing health literacy can be beneficial for promoting quality of life among these patients.
Highlights
Type 2 diabetes mellitus (T2DM) is a chronic disease that its related complications have reached epidemic levels, affecting the global economy and health [1, 2]
The mean health-related quality of life (HRQL) score found to be 49.14, which was similar to another study conducted in the Chaldoran city, West Azerbaijan, Iran (2017) that used the same measurement among patients with type 2 diabetes mellitus (T2DM) [36], and indicates that the patients with T2DM had a poor HRQL in both studies
Our findings revealed that the HRQL of the T2DM patients, especially in both mental and environmental domain, is low
Summary
Type 2 diabetes mellitus (T2DM) is a chronic disease that its related complications have reached epidemic levels, affecting the global economy and health [1, 2]. Diabetes caused 4 million deaths in 2017, and cost more than. Report of the World Health Organization (WHO) indicated that in 2016, diabetes was the 7th leading cause of death worldwide [5]. Regarding the importance of health literacy as a key factor in self-care, appropriate understanding of health information by patients with type 2 diabetes mellitus (T2DM) is fundamental for better management of risk factors, which can benefit their quality of life. This study aimed to describe the relationship between health literacy (HL), and self-care behaviors with health-related quality of life (HRQL) in patients with T2DM
