It was already known that men who father children later in their life are much more likely to have autistic children than younger men, but new research has found that this effect extends to their grandchildren also.

The new findings are the result of a collaboration between King’s College London’s Institute of Psychiatry, Karolinska Institutet in Sweden and the Queensland Brain Institute in Australia.

“By using Swedish national registers, researchers identified 5,936 individuals with autism and 30,923 healthy controls born in Sweden since 1932.

That type of delay is similar to the effects of other factors known to reduce fertility, such as smoking, obesity and older age, according to the findings, published today in Environmental Health Perspectives. Read full article.
