BACKGROUND: @entity1164 associated with physical exertion ( @entity5099 /E) is a complicated pathophysiological event. This study aims to calculate the incidence rate of @entity5099 /E in the US military population from 2005 to 2010, to characterise the demographic and cardiovascular risk profiles of decedents, and to evaluate aetiologies of and circumstances surrounding the deaths. METHODS: Perimortem and other relevant data were collected from the Armed Forces Medical Examiners Tracking System, Armed Forces Health Longitudinal Technology Application, and Defense Medical Epidemiology Database for decedents meeting @entity5099 /E case definition. Incidence rates were calculated and compared using negative binomial regression. RESULTS: The incidence of @entity5099 /E in the Active Component (ie, full-time active duty) US military from 2005 to 2010 was 1.63 per 100   000 @entity1 -years (py): 0.98 and 3.84 per 100   000 py in those aged <35 and >= 35   years, respectively. @entity65 was the leading cause of @entity204 overall (55%) and in the >= 35-year age group (78%), whereas the leading cause of @entity204 in the <35-year age group (31%) could not be precisely determined and was termed idiopathic @entity5099 /E (iSCD/E). @entity5099 /E was more common in males than females (incidence rate ratio (IRR) = 5.28, 95% CI 2.16 to 12.93) and more common in blacks than whites (IRR=2.60, 95% CI 1.81 to 3.72). All female cases were black. CONCLUSIONS: From 2005 to 2010, the incidence of @entity5099 /E in US military members aged <35   years was similar to most reported corresponding civilian @entity5099 rates. However, the leading cause of @entity204 was iSCD/E and not @entity296 . Improved surveillance and age-based prevention strategies may reduce these rates.
