London, June 30: If your child has higher intelligence quotient (IQ), he or she can live a longer life than children with lower IQs, according to researhers.
The study showed higher IQ in childhood is associated with certain diseases like heart disease, stroke, smoking related cancers, respiratory disease and dementia.
“The study confirms that intelligence test scores in childhood are significantly associated with subsequent mortality. Importantly, it shows that childhood IQ is strongly associated with causes of death that are, to a great extent, dependent on already known risk factors,” said Daniel Falkstedt, Assistant Professor at the Karolinska Institutet in Sweden.
“Tobacco smoking and its distribution along the socioeconomic spectrum could be of particular importance here. It remains to be seen if this is the full story or if IQ signals something deeper, and possibly genetic, in its relation to longevity,” Falkstedt added.
According to study, published in the journal The BMJ (British Medical Journal), the intelligence test measured at age 11 and leading causes of death in men and women up to age 79.
The findings are based on data from 33,536 men and 32,229 women born in Scotland in 1936.
