URINE SODIUM LEVEL IN THE 24-HOUR IN PATIENTS WITH NEWLY DIAGNOSED PRIMARY HYPERTENSION AT CAN THO UNIVERSITY OF MEDICINE AND PHARMACY HOSPITAL
Main Article Content
Abstract
Background: The relationship between the sodium intake so much and high blood pressure has been recognized by domestic and foreign authors. Quantifying 24-hour urine sodium level more accurately reflects high sodium salt intake. Objectives: (1) To evaluate the characteristics of mean 24-hour urine sodium level in patients with newly diagnosed primary hypertension; (2) To determine the relationship between the rate of people with increased 24-hour urine sodium level and patients with newly diagnosed primary hypertension. Materials and methods: A cross-sectional descriptive study was conducted in the patients group with newly diagnosed primary hypertension and the normal people group. Results: In the paitents group with newly diagnosed primary hypertension,the sex ratio female to male was 1.55. The average age of patients was 56.15±12.94, mostly age was ≥45 (83.2%). Mean 24-hour urine sodium level in the patients group and the normal group was 173.68±61.63 mmol/24hours and 86.34±31.73 mmol/24hours (p<0.01). The amount of 24-hour urine sodium increased with age in both groups, only the patients group with newly diagnosed primary hypertensive was no difference (p=0.051), in the normal group p<0.01. In people same age or sex, the patients group have 24-hour urine sodium level higher than in the normal people group,
p<0.01. The increase in 24-hour urine sodium level in the patients group and normal group were 17.6% and 0%, p=0.04. Conclusion: Mean 24-hour urine sodium level in the patients group with newly diagnosed primary hypertension was 173.68±61.63 mmol/24 hours, which was higher than the normal group and statistically significant. This level increased with age and male patients were higher than female patients. The proportion of people with high 24-hour urine sodium level was hypertension higher than people with normal 24-hour urine sodium level.
