Abstract
To study the effect of calcium and vitamin D supplementation on the incidence of toxaemia of pregnancy, 200 randomly selected pregnant women (supplemented group), were put on calcium (375 mg/day) and vitamin D (1,200 IU/day) supplemented at 20-24 weeks of pregnancy onwards. Another 200 pregnant women constituted the non-supplemented group. At 32 and 36 weeks of pregnancy the systolic and diastolic blood pressure of nontoxaemic women was significantly lower in the supplemented group than in the nonsupplemented group. However, the incidence of toxaemia in the supplemented group (6%) was not significantly different from that in the non-supplemented group (9%).
