The results suggest that babies born at high altitude are deprived of oxygen before birth.This may trigger the release or suppression of hormones that regulate growth of the unborn child, says Giussani.
His team also found that highaltitude babies tended to have relatively larger heads compared with their bodies.This is probably because a fetus starved of oxygen will send oxygenated blood to the brain in preference to the rest of t11e body.
Giussani wants to find out if such babies have a higher risk of disease in later life.People born in La Paz might be prone to heart trouble in adulthood.for example.Low birthweight is a risk factor for coronary heart disease.And newborns with a high ratio of head size to body weight are often predisposed to high blood pressure and strokes in later life.
