Heavier babies more likely to develop childhood allergies

A new study shows that babies who weigh more at any gestational age have a higher risk of later developing food allergies or eczema in childhood. However, there was no increase in the risk of hay fever. The paper published in the Journal of Allergy and Clinical Immunology found that the risk of food allergy went up by 44% and of eczema by 17% for each kilogram of added weight. On the other hand, restricted growth in the womb appears to be protective.
