Abstract

Background
Diabetes mellitus is a major problem worldwide. Moreover, older patients with significantly limited health literacy (HL) tend to have worse self-care behaviors and health outcomes. This study aimed to describe the associations of HL, self-care behavior, and blood sugar levels among older patients with type 2 diabetes in rural Thai communities.
Methods
This cross-sectional study included 415 patients with diabetes who were purposively selected from rural Thai communities. Data were collected using questionnaires and analyzed using descriptive statistics, Pearson correlation, Spearman rho, and stepwise multiple linear regression.
Results
The results revealed that most participants were women (66.50%). The respondents had moderate overall HL (2.68±0.64). On average, the respondents had fair overall self-care behavior (4.0±0.33). We discovered that HL was significantly positively correlated with self-care behavior (r=0.90) but not with blood sugar level. In addition, self-care behavior was significantly negatively correlated with blood sugar level (r=-0.50). Self-care behaviors and blood sugar levels were significant predictors of HL in patients with type 2 diabetes (total variance, 28.4%).
Conclusion
The results suggested increased HL in patients with diabetes would improve self-care behavior and, consequently, decrease their blood sugar level. Our findings indicate the need to involve nurses and multidisciplinary healthcare teams when developing health promotion programs to encourage blood sugar control.
