A recent study has found that that low IQ scores are linked to higher rates of death and disease in people.
The study, by a team of researchers from Scotland, was based on the IQ data collected from 1,347 men and women aged 56 in 1987, living in the West of Scotland, over a period of 17 years.
The IQ of the volunteers was assessed by written test and socioeconomic position by interview.
It was found that IQ scores follow a social trend and that though the poorest socioeconomic groups were at greatest risk of ill health and mortality, taking account of IQ markedly reduced these effects.
The study found that in half of the associations examined, disadvantaged people were twice as likely to risk ill health as advantaged people.
"Our findings indicate that IQ does not completely explain the health differences between rich and poor, but may contribute to them," The British Medical Journal quoted the authors, as saying.
"The currently scant information about IQ and health needs to be enhanced, with empirical investigation of why IQ might predict health and how the links between low socioeconomic status, low IQ, and poor health might be broken," they added.
