title: Influence of maternal nutritional status on vascular function in the offspring.
abstract: Suboptimal maternal nutritional status has been implicated in the development of cardiovascular risk in the child. Initially inferred from studies of low-birthweight children, investigations in cohorts of women subjected to famine provide direct evidence for an independent influence of the mother's diet on the cardiovascular health of her child. Animal studies from rodents and sheep have shown associations between maternal undernutrition and raised blood pressure, as well as abnormalities in resistance artery function, particularly in endothelium-dependent responses. Early life exposure to the influences of maternal over nutritional states, e.g. obesity and excessive gestational weight gain, has also been associated with markers of cardiovascular risk in man, and animal models have shown raised blood pressure and endothelial dysfunction in offspring of diet-induced obese dams. Increased sympathetic tone is commonly associated with hypertension in animal models of both under nutritional and over nutritional states. This and several other similarities may indicate commonality of mechanism and could reflect supranormal nutritional status in postnatal life in both conditions.
