Relationship of Sodium in Drinking Water and Toxemia of Pregnancy: A Pilot Study in Houston, Texas.
Abstract
This study is a retrospective case comparison analysis of the relationship of water-borne Na(+) and toxemia of pregnancy as a part of a continuous investigation at our facility on the role of various water constituents in human chronic disease. Five hundred thirty-seven toxemic women delivered at Jefferson Davis Hospital, Houston, Texas, during 1976 were matched by age, race, parity and month of delivery to 537 non-toxemic controls. Sodium concentration in each patient's drinking water was derived, based on her address, from earlier prepared maps of sodium distribution in Houston's water supplies. Paired t-tests were performed to compare the Na(+) levels which varied from 19 to 250 mg/1 in water supplies of cases and controls. Odds ration analysis was used to test for the presence of a gradient in occurrence of toxemia in parallel with the gradient of Na(+). No significant impact of water-borne Na(+) in the indicated range was observed. Further studies incorporating still higher ranges are contemplated. (Author)
