Effects of Dietary Principles Applied Program with the DASH Diet Model Coupled with Family Participation on Blood Pressure among the Hypertensive Elderly in Phen District, Udon Thani Province
Main Article Content
Abstract
The purpose of this quasi-experimental research was to study the effectiveness of the application of dietary principles in the DASH diet program with family participation on blood pressure in hypertensive elderly people. The subjects were elderly people with hypertension, including the 35 participants in each group. There were 12 weeks in the trial. The experimental group was given the DASH diet with family involvement as an application of dietary concepts. The researchers also developed tools for evaluating behavior and knowledge, and they collected data on blood pressure both before and after the trial.
Independent t-test statistics for the between-group comparison and paired t-test statistics for the within-group comparison reached the statistical significance level of 0.05. After the experiment, it was found that the experimental group's systolic blood pressure decreased significantly to 18.39 mmHg, 95% CI (15.02 to 21.75), p-value<0.001. Similarly, the diastolic blood pressure decreased by 3.61 mmHg, 95% CI (1.27 to 5.93), p-value=0.002. The studies show that a program causes a decrease in blood pressure in elderly people with hypertension. Therefore, the health care provider should be encouraged to implement the program.
