Attention‐deficit/hyperactivity disorder (AD/HD) is a common behavioral disorder among children, yet there is uncertainty about many aspects of AD/HD, including its precise frequency of occurrence, presence of comorbid conditions, long‐term outcomes and the impact of treatment on long‐term outcome. The objectives of the studies described in this paper were to address these important questions about AD/HD. The study subjects were from a population‐based birth cohort, and included all children born in Rochester, Minnesota, from 1976 to 1982, who remained in the community after the age of 5 y ( n = 5718). Complete medical and school records were available for all members of the birth cohort, including detailed information about AD/HD symptoms, psychometric test and questionnaire results, medical and non‐medical treatments, and long‐term academic and psychosocial outcomes. This information was used to identify 375 subjects from the birth cohort with AD/HD, based on well‐defined research criteria. The estimated cumulative incidence of AD/HD at the age of 19 y was 7.5% (95% confidence interval 6.5–8.4). Data from these 375 subjects with AD/HD will be used in ongoing studies of this disorder.
