A Salt Meter, 24-Hour Urine Sodium, Glomerular Filtration Rate, Uncontrolled Hypertension Patients


The objective of this quasi-experimental research was to examine the effects of the dietary education program in conjunction with the salt meter on reducing sodium intake, blood pressure levels, and glomerular filtration rate among uncontrolled hypertension patients. Participants were 50 uncontrolled hypertension patients who received services from the chronic non-communicable disease clinic, Ban Phue Hospital, and were divided into an experimental group of 25 people and a control group of 25 people. The experimental group received the dietary education program in conjunction with the salt meter for a period of 8 weeks. The control group received only the dietary education program. The research instrument was the dietary education program in conjunction with the salt meter. The data collection tools included a general data recording form, a blood pressure record form, and laboratory test results records, including 24-hour urine sodium content and glomerular filtration rate. The data were analyzed using descriptive statistics. Comparing the mean 24-hour urine sodium content, blood pressure level, and glomerular filtration rate with independent t-test statistics.

The results showed that the mean systolic blood pressure values between the experimental group and the control group before and after the program at the 8th week were statistically significantly different (p-value = 0.02). However, the mean 24-hour urine sodium content, the mean diastolic blood pressure, and the mean glomerular filtration rate between the experimental group and the control group before and after receiving the program at the 8th week showed no statistically significant differences. (p-value > 0.05). This research shows that this program can be used in patients with high blood pressure to promote healthy behaviors in order to control levels of blood pressure and prevent various complications that may occur in the future.
