Ontario Child Health Study: Prevalence of Attention Deficit Disorder with Hyperactivity
Abstract
Abstract The objective of this paper is to present data from the Ontario Child Health Study on the prevalence of attention deficit disorder with hyperactivity (ADDH). The overall prevalence of ADDH was 9.0% in hoys and 3.3% in girls. There were no significant differences in the prevalence of ADDH by age or urban‐rural status, but the disorder was significantly more common in boys than in twirls. The prevalence of various subtypes ADDH was also explored: attention deficit with and without hyperactivity, situational vs pervasive ADDH, and ADDH with and without other disorders. The clinical implications of these findings are discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
