A population based cohort study conducted in Denmark found that women had lower risk of asthma and better chances of remission. The research, published in BMJ Open, was aimed at describing the natural course of childhood asthma and examine the association between early life factors and childhood asthma. It found that although the female gender had a lower risk of asthma and a better chance of remission, maternal asthma history had an opposite effect. “The early life factors may influence the natural course of childhood asthma,” the researchers  said. 

The study analysed almost 1,93,673 children born during 1995-97 and followed the research up until 2009 and factors such as childhood asthma, including parity, maternal asthma history, maternal smoking during pregnancy, maternal social status, delivery method and gender were taken into account.
