Asthma? Granny’s fault?

In a study presented this year at the European Respiratory Society’s International Congress, research from Sweden suggested that cigarette smoking in previous generations can influence asthma risk in future generations.


There were about 45,000 grandmothers who smoked while they were pregnant with daughters between 1982 and 1986. Of the approximately 66,000 children later born from these daughters, there was a 10-22% increase in asthma risk, even if the mother did not smoke during pregnancy. No cause and effect relationship was established but the findings are of interest and more research is needed.
