Effect of Nutritional Education Promotion Program on Dietary Behaviors and Blood Pressure Level with Uncontrolled Hypertension in Suwannaphum Hospital

Abstract

Purposes : To compare the dietary behaviors and blood pressure levels of with uncontrolled hypertension patients in Suwannaphum Hospital.

Study design : Quasi-experimental research design; One group time series design.

Materials and Methods : The study focuses on a sample group comprising  uncontrolled hypertension patients from the hypertension clinic at Suwannaphum Hospital. The participants were selected based on in Inclusion Criteria. The data collection period spanned from January to May 2566, covering 15 weeks. Information was gathered through questionnaires and record forms. Data analysis involved the use of frequency, percentage, mean, standard deviation, paired t-test and one-way repeated measures ANOVA with Bonferroni post hoc tests for pairwise comparisons.

Main findings : 1) After the experimental period, it was observed that sample group exhibited a statistically significant increase in the average score of dietary behavior compared to  control period (p < .001). The mean score of dietary behavior was higher by 1.72 points (95% CI: 1.40, 2.03). 2) The sample group showed a difference in mean scores of systolic blood pressure after the control period compared to experimental period, with the maximum increase being 14.72 mmHg. This was followed by period before control, with a mean increase of 14.00 mmHg. 3) The sample group demonstrated a difference in mean scores of diastolic blood pressure, with highest increase occurring before control period compared to the experimental period, equal to 8.22mmHg. The subsequent decrease was observed between periods before experimentation and after experimentation, with a mean decrease of 6.11 mmHg.

Conclusion and recommendation : The findings of this research indicate that developed intervention has resulted in improved clinical outcomes for patients.
