Abstract

Purpose: To assess the association between adult Attention Deficit-Hyperactivity Disorder(ADHD) and motorcycle rider traffic injuries

Methods: A case-control study was conducted over a period of six months in 2012. Two hundred and five motorcycle riders involved in traffic accidents, and 200 age-matched non-traumatic controls were enrolled. The Conners' Adult ADHD Rating Scale (CAARS) self-report (screening version) was used for screening in both groups. Finally the score of ADHD was compared between the groups and associations were assessed using multivariate logistic regression analysis.

Results: Two hundred and five males were recruited with a mean age of 24.3±10.2 years in the case and 25.0 ±7.7 years in control groups. Univariate Analysis showed significant association with educational level, job, daily riding amount, driving at night, helmet usage, motorcycle engine size, household income, individual income and socio-economic status. In all ADHD subscales (A,B,C,D), significant associations were found and all subscale scores were higher in the case group. Multivariate analysis confirmed the association of ADHD screening score with motorcycle traffic injuries.

Conclusions: The results indicated existance of an association between Adult ADHD and motorcycle traffic injuries.
