Cognitive epidemiology is a field of research that examines the
associations between intelligence test scores (IQ scores or extracted
g-factors) and health, more specifically morbidity (mental and
physical) and mortality. Typically, test scores are obtained at an
early age, and compared to later morbidity and mortality. In addition
to exploring and establishing these associations, cognitive
epidemiology seeks to understand causal relationships between
intelligence and health outcomes. Researchers in the field argue that
intelligence measured at an early age is an important predictor of
later health and mortality differences.A strong inverse correlation
between early life intelligence and mortality has been shown across
different populations, in different countries, and in different
epochs."A study of one million Swedish men found showed "a strong link
between cognitive ability and the risk of death."A similar study of
4,289 former US soldiers showed a similar relationship between IQ and
mortality.
