Mums’ asthma linked to below-weight babies

INFANTS whose mothers suffer asthma exacerbations while pregnant may be more likely to fail to thrive in the first six months of life, research suggests.

In a study of 120 mother-baby pairs, researchers from Newcastle in the NSW Hunter Valley found infants of mothers who had asthma weighed 0.5 kg less at six months of age than those born to mothers without the disease.

And mothers with asthma who had exacerbations in pregnancy had babies weighing an average 7.2 kg at six months, compared to 7.7 kg for infants of those who had no asthma attacks.
