Attention deficit hyperactivity disorder (ADHD) is a frequent condition in school-age children and commonly presents in comorbidity with other psychiatric diseases. In Brazil, there are few studies concerning non-clinical samples.
The present study aims to calculate the prevalence of this disorder and its comorbidities in a sample of school-age children.
Cross-sectional analytic study was conducted on a non-clinical sample of children and adolescents registered in 2003 in the elementary school of the Federal University of Rio de Janeiro. A screening questionnaire was used and parents of those possible affected children were invited for a clinical structured interview.
The prevalence of ADHD was 8.6%. Comorbidities were present in 58% of the cases and oppositional-defiant disorder was the most common, found in 38.5%.
The prevalence of ADHD and its comorbidities in this sample is similar to that observed in the literature.
注意缺陷多动障碍（ADHD）在学龄儿童中很常见，并且通常与其他精神疾病合并出现。在巴西，关于非临床样本的研究很少。
本研究旨在计算该障碍及其合并症在学龄儿童样本中的患病率。
对2003年在里约热内卢联邦大学小学注册的儿童和青少年非临床样本进行横断面分析研究。使用了一份筛查问卷，并邀请那些可能受影响儿童的家长进行临床结构化访谈。
ADHD的患病率为8.6%。58%的病例存在合并症，对立违抗障碍最为常见，占38.5%。
该样本中ADHD及其合并症的患病率与文献中观察到的相似。
