Impact of functional, communicative and critical health literacy on glycemic control among patients with type 2 diabetes, and the mediating role of self-care

The Effect of Culturally Appropriate Self-Care Intervention on Health Literacy, Health-Related Quality of Life and Glycemic Control in Iranian Patients with Type 2 Diabetes: A Controlled Randomized Clinical Trial

Background

Cultural and language differences are necessary factors for diabetes management and self-care education programs in patients suffering from diabetes. This study aims to investigate the effectiveness of culture-based self-care intervention on health literacy, quality of life, and glycemic parameters in patients with type 2 diabetes.

Materials and Methods

This randomized clinical trial has been carried out in selected centers in Darreh Shahr, Iran; 80 participants were randomly assigned into intervention and control groups. The intervention group received an educational program for 6 sessions twice a week, but the control group only received routine services. Data were collected using health literacy and life quality scales for diabetic patients, which were completed by both groups before, immediately after, and 3 months after the intervention; hemoglobin A1C (HbA1c) was checked before and 3 months after the intervention. SPSS software was also analyzed data using χ2, Fisher's exact, independent t, and repeated measures analysis of variance tests.

Results

There were no significant differences between the 2 groups before the study (p >0.05) goes forward. But, mean scores of health literacy (F2,40 = 5.61, p =0.007), quality of life (F2, 40 = 4.09, p =0.01), and HbA1c levels (t, 39 = 6. 91, p <0.001) have shown significant differences between the 2 groups immediately and 3 months after the intervention have been applied.

Conclusions

Culturally appropriate intervention should be offered as a part of the nurse' care program for diabetic to control HbA1c, and improve their life quality and health literacy.

Frailty, Health Literacy, and Self-Care in Patients with Chronic Kidney Disease in Taiwan

Chronic kidney disease (CKD) is a chronic and often irreversible disease that requires active self-care to mitigate adverse outcomes. This study aimed to analyze the associations of demographic and disease data, frailty, health literacy (HL), and CKD self-care (CKDSC) in patients with CKD. We conducted a cross-sectional study at two hospitals in Taiwan. A total of 144 CKD patients with a mean age of 66.8 ± 9.1 years were included in the study. Among them, 79.2% were in CKD G3, and the mean time since diagnosis of CKD was 86 ± 48 months. Approximately 62.5% were identified as non-frail. The mean of HL and CKDSC were 11.76 ± 4.10 and 62.12 ± 9.31. In multivariate linear regression analysis, age ≥ 65 years (odds ratio (OR) = 5.67, 95% confidence interval (CI) 1.59–9.75), non-frailty (OR = 2.19, 95% CI 0.02–5.40), and high critical HL (OR = 1.43, 95% CI 0.13–2.90) showed significant positive correlation with CKDSC. Therefore, management of patients with CKD should focus on the young population, reinforcing health education strategies that improve critical HL and preventing frailty that may interfere with self-care. In addition, the patient’s social support resources should be expanded to achieve the goal of CKDSC.

Building a House of Skills-A Study of Functional Health Literacy and Numeracy among Patients with Type 2 Diabetes in Hungary

The purpose of this study is to explore functional health literacy (FHL) and numeracy skills in an insulin-treated, type 2 diabetes mellitus (T2DM) patient population, and their impact on diabetes self-care activities. A non-experimental, cross-sectional quantitative design was used for this study. The sample consisted of 102 T2DM patients on insulin therapy, including 42 males and 60 females, with a mean age of 64.75 years (SD = 9.180) and an average diabetes duration of 10.76 years (SD = 6.702). Independent variables were sociodemographic variables (e.g., age, educational level, etc.) and diabetes and health-related factors (e.g., duration of diabetes (years), the frequency of blood glucose testing/day, etc.). For this study, the participants completed the reading comprehension exercise from the Short Test of Functional Health Literacy (S-TOFHLA) and the Shortened Version of the Diabetes Numeracy Test (DNT-15), which specifically evaluates the numeracy skills of patients living with diabetes. The associations between the variables were examined with Spearman’s rank correlation. Multivariate regression analysis was performed to examine whether measured FHL skills impact diabetes self-care activities. We found that DNT-15 test (β = 0.174, t(96) = 2.412, p < 0.018) had significant effect on the frequency of blood glucose testing/day. Moreover, the problem areas for patients with T2DM mostly included multi-step calculations according to food label interpretations, and adequate insulin dosage based on current blood glucose levels and carbohydrate intake. The results of regression analyses and Spearman’s rank correlation indicated that limited FHL and diabetes numeracy skills not only influenced the participants’ behaviors related to self-management, but they also affected their health outcomes. Thus, besides the personalization of insulin treatment, it is indispensable to provide more precise information on different types of insulin administration and more refined educational materials based on medical nutrition therapy.

The Association of Health Literacy Level with Self-Care Behaviors and Glycemic Control in a Low Education Population with Type 2 Diabetes Mellitus: A Cross-Sectional Study in Iran

INTRODUCTION

Promoting Health Literacy (HL) can be a priority in strategic healthcare planning of the countries. Low HL is prevalent in some societies which make barriers to successful self-care of diseases. The aim of this study was to examine the association of HL with self-care behaviors and glycemic control in a low education population with type 2 diabetes mellitus.

METHODS

This cross-sectional study was conducted in Sarab city, Iran. The 192 participants were patients diagnosed as type 2 diabetes and with low level of education. Convenient sampling method was applied and the participants were chosen by their medical records in health-care centers. To collect data a valid and reliable tool was used based on HL dimensions and self-care behaviors. Using hierarchical logistic regression, the possible association of variables with self-care behaviors and glycemic control was assessed.

RESULTS

The mean age of study participants was 58.12 (±11.83) years. A 28.8% of the variation in the self-care behaviors is explained by the HL and the demographic variables (R= 0.288%; p-value<0.05). Furthermore, decision-making was the strongest predictor of self-care behaviors (β= 0.451). Approximately 80% of the variation in the HbA1c is explained by the HL, self-care behaviors, and the demographic variables (R= 0.804%; p-value<0.05).

CONCLUSION

This study revealed that the HL dimensions predicted approximately one-fourth of self-care behaviors and the self-care behaviors and HL dimensions about eight-tenths of HbA1c in this population. These findings call for the need for interventional programs on HL to improve the self-care behaviors and HbA1c control.
