Keywords:health literacy, self-care behavior, diabetes, chronic kidney disease
Introduction: Health literacy development is important for health behavior improvement leading to good clinical outcomes of uncontrolled diabetes patients at risk of developing chronic kidney disease. Research objectives: To examine the effects of health literacy development program on health literacy, self-care behaviors, blood sugar, glomerular filtration rate, and urine microalbumin of type 2 diabetes patients at risk of developing chronic kidney disease. Research methodology: The study used a quasi-experimental two-group pretest-posttest design. A stratified random sampling technique was used to recruit 32 participants. Then, 32 participants were assigned to the intervention group and 35 to the control group. All of them lived in Wangsaipun district, Phichit province. Research instruments were: 1) the program of health literacy development for type 2 diabetes patients at risk of chronic kidney disease based on the concept of update on health literacy and diabetes. Duration of the program was 12 weeks, and the activities kidney were a workshop and home visits; 2) Handbook of health literacy for slowing down of renal failure from diabetes; and 3) health literacy and self-management behavior questionnaires. Content validity indexes were 1.00 and 0.99; and the reliability were 0.95 and 0.84, respectively. Data were analyzed using descriptive statistics, t-test, and non-parametric statistics. Results: At follow-up, mean of health literacy, self-care behaviors, and glomerular filtration rate of the intervention group was significantly higher than baseline and significantly greater than the control group (p< .01). At follow-up, blood sugar and urine microalbumin of the intervention group were significantly lower than baseline and significantly lower than the control group (p<0.01). Conclusions: The health literacy development program for patients with type 2 diabetes at risk of chronic disease had affected on health literacy, self-care behavior, and clinical outcomes to delay chronic kidney disease. Implications: The uncontrolled type 2 diabetes patients who had blood glucose at 155-182 milligram per deciliter and glomerular filtration rate at medium stage at risk of chronic kidney disease should develop health literacy using the health literacy development program.
