Higher IQ in childhood linked to longer life: Study

New Delhi: Higher intelligence (IQ) in childhood is often associated with lower risk of acute illness like heart disease, stroke, smoking related cancers, respiratory disease and dementia, a study has found.


Researchers found that if the child is smart and has higher IQ, he or she can look forward to a longer life than children with lower IQs.

Further, lifestyle, especially tobacco smoking, can be an important component in the effect of intelligence on differences in mortality, the researchers said.

“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.

Their findings are based on data from 33,536 men and 32,229 women born in Scotland in 1936, who took a validated childhood intelligence test at age 11, and who could be linked to cause of death data up to December 2015.
