| Popis: | Epidemiological and prospective studies in man and animals have indicated an inverse relationship between calcium intake and cardiovascular mortality and blood pressure (BP). We have therefore studied the effect of dietary calcium on blood pressure in two groups of women. In a cross-sectional study 103 early postmenopausal women were stratified into three groups according to daily calcium intake calculated from a questionnaire. Both diastolic and systolic blood pressures were identical in the three groups. We thereafter conducted a prospective placebo-controlled trial on the effect of calcium supplementation. Twenty-eight healthy women were randomized to placebo treatment (n = 14) or calcium supplementation 2,000 mg daily (n = 14) for one year. In both groups BP remained at initial levels throughout the study and was identical in the two groups at measurements every three months. We thus conclude that calcium supplementation has no effect on BP in normotensive subjects on a high calcium diet. |
