Sodium and potassium excretion in normotensive and hypertensive population in Kashmir.J Assoc Physicians India. 2006 Jan; 54:22-6.JA
One hundred thirty five hypertensive patients and equal number of age and sex matched healthy controls were taken up for studying the relationship of 24 hour urinary sodium and potassium excretion, sodium-potassium molar ratio and body mass index (BMI) with blood pressure in normotensive and hypertensive population in Kashmir. There was statistically significant elevated 24 hour urinary sodium excretion (p < .001), increased Na+-K+ molar ratio, significantly higher BMI in hypertensive population as compared to controls whereas there was a lower 24 hour urinary excretion of potassium (p > .20) in patients with hypertension. Thus sodium and potassium excretion, Na+-K+ molar ratio and body mass index has direct bearing in perpetuation or causation of hypertension in Kashmir which may be related to intake of salt tea.
