DangersAwait Babies with Altitude
Women who live in the world’shighest communities tend to give birth to under-weight babies, a new studysuggests. These babies may grow into adults with a high risk of heart diseaseand strokes.1
Research has hinted that newborns in mountaincommunities are lighter than average. But it wasn’t clearwhether this is due to reduced oxygen levels at high altitude or because theirmothers are under-nourished — many peoplewho live at high altitudes are relatively poor compared with those living lowerdown.
To find out more, Dino Giussani and his team atCambridge University studied the records of 400 births in Bolivia during 1997and 1998. The babies were bom in both rich and poor areas of two cities: La Pazand Santa Cruz. La Paz is the highest city in the world, at 3.65 kilometersabove sea level, while Santa Cruz is much lower, at 0.44 kilometers.
Sure enough, Giussani found that the averagebirthweight of babies in La Paz was significantly lower than in Santa Cruz.This was true in both high and low-income families. Even babies bom to poorfamilies in Santa Cruz were heavier on average than babies born to wealthyfamilies in lofty La Paz. “We were verysurprised by this result,” saysGiussani.
The results suggest that babies born at highaltitude are deprived of2 oxygen before birth. “This maytrigger the release or suppression of hormones that regulate growth of theunborn child.3 ‘‘ says Giussani.
His team also found that high-altitude babiestended to have relatively larger heads compared with their bodies4. This isprobably because a fetus starved of oxygen will send oxygenated blood to thebrain in preference to the rest of the body5.
Giussani wants to find out if such babies havea higher risk of disease in later life. People born in La Paz might be prone toheart trouble in adulthood, for example. Low birthweight is a risk factor forcoronary heart disease. And newborns with a high ratio of head size to bodyweight are often predisposed to high blood pressure and strokes in later life.
