摘要: Abstract On Colorado's eastern plains a region of relatively high hypertension risk became manifest by about 1960, suggested mortality statistics and corroborated independent morbidity data. Looking for changing environmental factors to associate with the pattern risk, results statewide study municipal water supply constituents were analyzed. Schroeder's inverse correlation between hardness could not be confirmed in Colorado. The rate actually tended higher regions harder where use cation-exchange water-softening equipment continues proliferate augment sodium intake. However, nitrate concentration was constituent most strongly associated Since organic nitrates have been shown increased diastolic among explosives workers, there is reason suspect causative relationship levels supplies emergent geographic risk.
