Blood pressure and drinking water's magnesium level in some Serbian Municipalities

Chronic exposure to lower level of magnesium (Mg) in drinking water increases risk of magnesium deficiency and its potential association with Hypertension. The aim of the study was to assess the effect of mineral contents in drinking water on blood pressure in healthy population. The study was cross-sectional, recruited 90 healthy blood donors, 20 to 50 years age, from tree municipalities. Area of one, Pozarevac, had four times higher mean Mg level in drinking water (42 mg/l), than other, Grocka, (11mg/l). Diastolic blood pressure was the lowest in subjects from Pozarevac. Serum Mg was significantly highest and Ca/Mg lowest in subjects from Pozarevac, and after adjustment for confounders (age, gender, BMI), only total cholesterol and serum Mg level were independent predictors of diastolic blood pressure in subjects from these tree municipalities. Therefore, Mg supplementation in area of lower magnesium level in drinking water may be an important tool in prevention of Hypertension.
