Suicide in National Collegiate Athletic Association athletes: a 20-year analysis
Objectives To determine the incidence rate of suicide from 2002 to 2022 among athletes from the National Collegiate Athletic Association (NCAA) and assess for potential differences by, sex, race, division and sport. Methods NCAA athlete deaths over a 20-year period from 2002 to 2022 were identified. Poisson regression models were built to assess changes in incidence rates over time. Linear and quadratic fits between year and suicide incidence for males and females were evaluated. Results Of 1102 total deaths, 128 (11.6%) deaths by suicide were reported (male n=98, female n=30). The overall incidence was 1:71 145 athlete-years (AYs). Over the last decade, suicide was the second most common cause of death after accidents. The proportion of deaths by suicide doubled from the first 10 years (7.6%) to the second 10 years (15.3%). The suicide incidence rate for males increased linearly (5-year incidence rate ratio 1.32 (95% CI 1.14 to 1.53)), whereas a quadratic association was identified am
