High birth weight may increase risk of atopy and asthma

According to a Finnish study of 6,000 children, there was a significant association between high birth weight (bigger than 4,5 kg) and atopy and asthma.

The biological mechanisms behind the associations are unknown, but they could be related to obesity.
