The analysis found no statistically significant differences in the total scores of HL and NL between baseline and post-intervention. However, slight improvements in HL and NL levels were noted in the intervention groups, along with small improvements in knowledge and behaviors related to hypertension and dietary salt. The findings suggest that while the program was well-received, new evidence-based research is needed to guide effective HL- and NL-based interventions in the Greek healthcare system.

ABSTRACT

Abstract BACKGROUND: Suboptimal control of blood pressure (BP) is a public health challenge in Greece. This educational intervention attempts to improve health literacy (HL) and nutrition literacy (NL) in primary healthcare (PHC) patients with hypertension (HTN). MATERIALS AND METHODS: This was a proof-of-concept (PoC) educational intervention. Twenty-four patients with HTN and low or medium levels of HL agreed to participate in this 6-week educational intervention. The program was delivered by a general practitioner (GP) in group A and by a qualified nurse in group B. Group C was the control group. The levels of HL of NL, adherence to the Mediterranean diet, and perceived stress were assessed using the European Health Literacy Survey Questionnaire 16 (HLS_EU_Q16) and part B (reading a medication label) of the High Blood Pressure–Health Literacy Scale (HBP–HLS), the Nutrition Literacy Scale-Greek (NLS-Gr), the Mediterranean Diet Adherence Screener (MEDAS), and the Perceived Stress Scale (PSS-14), respectively, together with certain socioeconomic, dietary, and lifestyle characteristics. The Kruskal–Wallis and Wilcoxon nonparametric, the Chi-square, and the McNemar–Bowker tests were used. The analysis was done with the STATA software, version 14 (MP & Associates, Sparta, Greece). RESULTS: No statistically significant differences were found in the total score of HL and NL before and after the intervention; however, the results indicate a slight improvement in HL and NL levels in the two intervention groups, together with small improvements in knowledge and behaviors related to HTN and dietary salt. A trend of improvement in the MEDAS levels in the GP's group and the HBP–HLS levels in the nurse's group was also reported. CONCLUSION: A slight improvement in HL and NL levels in the two intervention groups has been reported, and the changes, however, were not statistically significant.
