Prevalence and clinical characteristics of attention deficit hyperactivity disorder among primary school students in Bangkok.
Attention deficit hyperactivity disorder (ADHD) is an important disorder because it is the most prevalent chronic health condition affecting school aged children. Children with ADHD are at risk for academic and behavior problems. There are several studies in many countries worldwide. In Thailand, there have been a few published papers about ADHD. Most of them were studies in a clinically referred population. Four hundred and thirty-three first to sixth grade students from Wat Samiennaree School were included in this study. All children were administered Raven's progressive matrices test for estimation of intellectual functioning and were observed for their behavior in the classrooms by one researcher. Their demographic data was collected by questionnaires. The revised Conners rating scales were scored for each student. Students whose parents did not score the Conners parent rating scale were excluded. The parents of students, whose scores were positive for ADHD, were interviewed according to DSM IV criteria. 353 (81.5%) students from 433 were enrolled in this study. 23 students were diagnosed with ADHD making a prevalence of 6.5 per cent. There were 11 boys and 12 girls. The ratio of male to female was 1:1.09. The ADHD students had lower scores in mathematics than the group without this diagnosis with statistical significance (p = 0.006).
