“…Person-years at risk were counted beginning at separation from active duty and ending on death or December 31, 2009, whichever came first. The National Institute for Occupational Safety and Health Life Table Analysis System version 3.0.3, software was used to obtain standardized mortality ratios (SMRs) and 95% confidence intervals (CIs) for each cause-of-death category [23]. The SMR is the ratio of the observed deaths among veterans to the expected deaths calculated from the mortality rates for the US general population (referent population) adjusted for gender, race, age, and calendar period.…”

Objective: To analyze neurodegenerative causes of death, specifically Alzheimer disease (AD), Parkinson disease, and amyotrophic lateral sclerosis (ALS), among a cohort of professional football players. Methods:This was a cohort mortality study of 3,439 National Football League players with at least 5 pension-credited playing seasons from 1959 to 1988. Vital status was ascertained through 2007. For analysis purposes, players were placed into 2 strata based on characteristics of position played: nonspeed players (linemen) and speed players (all other positions except punter/kicker). External comparisons with the US population used standardized mortality ratios (SMRs); internal comparisons between speed and nonspeed player positions used standardized rate ratios (SRRs). Results:Overall player mortality compared with that of the US population was reduced (SMR 0.53, 95% confidence interval [CI] 0.48Ϫ0.59). Neurodegenerative mortality was increased using both underlying cause of death rate files (SMR 2.83, 95% CI 1.36Ϫ5.21) and multiple cause of death (MCOD) rate files (SMR 3.26, 95% CI 1.90Ϫ5.22). Of the neurodegenerative causes, results were elevated (using MCOD rates) for both ALS (SMR 4.31, 95% CI 1.73Ϫ8.87) and AD (SMR 3.86, 95% CI 1.55Ϫ7.95). In internal analysis (using MCOD rates), higher neurodegenerative mortality was observed among players in speed positions compared with players in nonspeed positions (SRR 3.29, 95% CI 0.92Ϫ11.7). Conclusions:The neurodegenerative mortality of this cohort is 3 times higher than that of the general US population; that for 2 of the major neurodegenerative subcategories, AD and ALS, is 4 times higher. These results are consistent with recent studies that suggest an increased risk of neurodegenerative disease among football players.

“…The National Institute for Occupational Safety and Health (NIOSH) Life Table Analysis System (LTAS) mortality programme was used to calculate SMRs and 95% CIs for the cohort stratified by 5-year age groups and calendar year 22. Age-specific, race-specific and calendar year-specific mortality rates for US men were applied to the cohort's person-years distribution to calculate cause-specific expected numbers of deaths.…”
