Women who exercise during pregnancy produce \’lighter babies\’
Dr Paul Hofman, from the University of Auckland in New Zealand, said: \’\’Our findings show that regular aerobic exercise alters the maternal environment in some way that has an impact on nutrient stimulation of fetal growth, resulting in a reduction in offspring birth weight.
\’\’Given that large birth size is associated with an increased risk of obesity, a modest reduction in birth weight may have long-term health benefits for offspring by lowering this risk in later life.\’\’
The snigger is that smoking also reduces birth weight. Which, if reducing birth weight is a good thing, rather makes a mockery of the advice given for decades that women shouldn\’t smoke during pregnancy because it will reduce the weight of their babies.
