BackgroundHealth literacy is the ability of a person to acquire the process, understand the necessary health information, and make the health services needed for conscious health decisions. Low levels of health literacy can impair the healthcare and treatment of chronic diseases such as diabetes. Besides, diabetes is the most common metabolic disorder that affects patients' quantity and quality of life. Health literacy means cognitive and social skills, with the motivation and ability to understand and use health information, helping individuals maintain and promote their good health. This study focused on determining the factors that affect the health literacy status of type 2 diabetes patients through the role of the demographic variables.MethodologyThis descriptive-analytical research survey recruited a sample based on 280 diabetic patients at the Diabetes Research Center of Ayatollah Taleghani Hospital in Kermanshah in 2020 through a cross-sectional study design. This study selected the diabetes patients using the technique of a simple random sampling and study applied the tools of demographic information questionnaire and the functional, communicative and critical health literacy scale (FCCHL) to collect data of diabetes patients. This study used the SPSS version-23 on the received data sets to perform statistical analysis, including t-test, ANOVA, and multiple regression, to predict the factors affecting health literacy among diabetes patients.ResultsThe results showed the mean age of the participants 55.80±13.04 of diabetes patients. The mean and standard deviation of the health literacy score in diabetic patients indicated 2.70±0.44, respectively. The findings specify that there is a statistically significant relationship between health literacy, gender, education, occupation, income, and place of residence. The most robust predictors of health literacy are income variables (β=0.170), age (β=0.176), and employment (β=0.157).ConclusionThe results of this research study specified that the health literacy rate of individuals with diabetic type 2 is an average level. The potential communicative and critical health literacy influence essential for communication and education for diabetes patients in the settings of the primary health care system. The findings indicate that communicative and critical health literacy related to patients’ management and patients with functional health literacy looks passable in this study. The health information specialists need to recognize diabetes patients’ demographic variables according to their needs. Health professionals’ abilities to deliver health education resources seems critical, as it would improve health-related behavior by increasing literacy level.
