Abstract
Background: The survey on the health behaviors of individuals at risk for hypertension found that this group consumes sweet, oily, and salty foods and lacks the necessary knowledge to choose nutritious foods. Additionally, they do not exercise. If these issues are not addressed, new cases of hypertension will continue to emerge.
Methods: This study is a quasi-experimental research with a two-group pretest-posttest design. The objective was to compare knowledge, behaviors in reducing high-sodium food consumption, sodium levels in urine, sodium content in food, and blood pressure levels. The sample consisted of individuals at risk of hypertension in Khuan Don District, Satun Province, divided into an experimental group of 37 participants and a comparison group of 37 participants. Data were collected through interviews. Descriptive statistics, such as percentage, mean, median, range, quartiles, and standard deviation, were used for data analysis, along with inferential statistics, including the Wilcoxon matched-pairs signed-rank test and the Mann-Whitney U test.
Result: The study presents the different between experimental group and the comparison group in knowledge about sodium-containing in food (P=0.013), score of behaviors for reducing of high sodium foods consumption (P=0.003), sodium concentration in food (P <0.001), systolic blood pressure (P=0.027), and diastolic blood pressure (P=0.006)
