The relationship between deficient dietary calcium intake during pregnancy and the occurrence of pre-eclampsia: A review

Abstract:

Relevant literature is reviewed concerning the hypothesis that lack of adequate calcium intake during pregnancy is related to the occurrence of pre-eclampsia. Epidemiologic observations indicate that in countries with low daily calcium intake, the incidence rates for eclampsia are high, while in those with high calcium intakes, the rates for eclampsia are low. Such observations do not control for confounding factors, yet clinical studies in animals and humans lend additional support to the hypothesis. Pregnant and non-pregnant rats with deficient dietary calcium exhibit significantly higher blood pressure levels than calcium-fed controls. Lack of adequate dietary calcium may result in increased vascular tension which causes elevation of blood pressure. The unique metabolic demands of gestation require increased calcium intake by pregnant women. Failure to meet the increased need for calcium during pregnancy may promote maternal pre-eclampsia hypertension. It is suggested that pregnant women seek to meet the 1200 gm recommended daily allowance for calcium intake during gestation.
