Hagger-Johnson, Gareth J. Deary, Ian A. Davies, Carolyn Weiss, Alexander David Batty, G. Reaction Time and Mortality from the Major Causes of Death: The NHANES-III Study <div><p>Objective</p><p>Studies examining the relation of information processing speed, as measured by reaction time, with mortality are scarce. We explored these associations in a representative sample of the US population.</p><p>Methods</p><p>Participants were 5,134 adults (2,342 men) aged 20–59 years from the Third National Health and Nutrition Examination Survey (NHANES III, 1988–94).</p><p>Results</p><p>Adjusted for age, sex, and ethnic minority status, a 1 SD slower reaction time was associated with a raised risk of mortality from all-causes (HR = 1.25, 95% CI 1.12, 1.39) and cardiovascular disease (CVD) (HR = 1.36, 95% CI 1.17, 1.58). Having 1 SD more variable reaction time was also associated with greater risk of all-cause (HR = 1.36, 95% CI 1.19, 1.55) and CVD (HR = 1.50, 95% CI 1.33, 1.70) mortality. No associations were observed for cancer mortality. The magnitude of the relationships was comparable in size to established risk factors in this dataset, such as smoking.</p><p>Interpretation</p><p>Alongside better-established risk factors, reaction time is associated with increased risk of premature death and cardiovascular disease. It is a candidate risk factor for all-cause and cause-specific mortality.</p></div> neuroscience;Cognitive neuroscience;cognition;Population biology;epidemiology;Epidemiology of aging;Population metrics;Death rate;aging;Anatomy and physiology;Physiological processes;cardiovascular;Clinical research design;Cohort studies;Survey research;Cardiovascular disease epidemiology;Mental health;psychology;behavior;Attention (behavior);neurology;Cognitive neurology;Non-clinical medicine;Health care policy;Health risk analysis;Public health;Cognitive psychology;Human intelligence;neuropsychology;Psychometrics;Sociology;demography;causes;nhanes-iii 2014-01-29
