An association between childhood cognitive ability measured by IQ tests and mortality has been reported recently. It is not clear from those studies to what extent the increased relative risk associated with lower IQ scores may be attenuated by adjustment for other risk factors. This study aims to investigate the association between cognitive ability measured at age 18-20 years and mortality among middle-aged men adjusting for risk factors for mortality over the life course.
