Attention deficit and hyperactivity disorder among school children in Kinshasa, Democratic Republic of Congo.

Abstract

To estimate the prevalence and determinants of attention deficit and hyperactivity disorder (ADHD) symptoms among school children in Kinshasa, an African urban setting. The 18-items of the Disruptive Behaviour Disorder rating scale (DBD), which is based on the Diagnostic and Statistical Manual for mental disorders 4(th) edition (DSM-IV), were used to investigate the presence of ADHD symptoms. Parents interviews, using a questionnaire specially designed for the study, were performed to identify socio-demographic characteristics. All children were subject to a clinical examination. The estimated prevalence of DSM-IV ADHD symptoms was 6%. Those with family health problems, younger age at start of primary school, good nutritional status and poor school performance more often had DSM-IV ADHD symptoms. ADHD symptoms are as common among school children in Kinshasa as elsewhere. The socio-demographic factors described as risk factors for ADHD in high-income countries were not identified in this study.
