An experimental randomized controlled trial was conducted to evaluate the effects of Mediterranean diet education on blood pressure levels and quality of life in hypertensive patients. The sample size was determined using power analysis (n=70). Data were collected using a General Information Form, Physical Activity Questionnaire, Perceived Stress Scale, SF-36 Quality of Life Scale, and Mediterranean Diet Adherence Scale. Both groups were administered the questionnaire and blood pressure measurements at 0, 1, and 3 months. The first application was administered to the intervention group before the education session.

The experimental randomized controlled trial was conducted to evaluate the effect of Mediterranean diet education on blood pressure levels and quality of life in hypertensive patients. The sample size was determined using power analysis (n=70). Patients who met the inclusion criteria were assigned to the experimental (n=35) and control (n=35) groups using a simple randomization technique. Data were collected using the General Information Form, Physical Activity Questionnaire, Perceived Stress Scale, SF-36 Quality of Life Scale, and Mediterranean Diet Adherence Scale. Surveys and blood pressure measurements were administered to both groups at 0, 1, and 3 months. The initial application for the intervention group was conducted before the education session. In data evaluation, percentages, means, independent t-tests, Pearson chi-square tests, Yates chi-square tests, repeated measures variance analysis (ANOVA), Pearson correlation tests, and Bonferroni tests were used.
