For causes of death that were considered chronic (eg, cancer, liver disease, cardiovascular disease), AAD and YPLL were estimated for decedents aged 20 years or older; for the majority of acute conditions, they were estimated for decedents aged 15 years or older. However, ARDI also estimates AAD and YPLL for chronic conditions for persons younger than 20 years who died from conditions attributable to drinking during pregnancy (eg, fetal alcohol spectrum disorders) and for acute conditions for persons younger than 15 years who died from motor-vehicle traffic crashes or child maltreatment. ARDI provides reports of AAD and YPLL by sex, age group, and state, and for those under age 21 years.
