Children are more likely to develop asthma if their father was exposed to secondhand smoke as a child

 according to a new study published in the European Respiratory Journal.

the study also shows that children`s asthma risk is even higher if their father was exposed to secondhand smoke and became a smoker.

The team compared data on whether children had developed asthma by the age of seven 

smokers "We found that the risk of non-allergic asthma in children is increased by 59%

The risk was even higher, 72%, if the parents were exposed to secondhand smoke and later smoked.

The findings show how the harm caused by smoking can impact not only smokers 

children and grandchildren, although the risk may be reduced in their grandchildren if their children avoid smoking.

The researchers will now investigate whether the increased risk of asthma persists into adult life
