I have already covered the growing peer-reviewed research base looking at the diagnosis of attention-deficit hyperactivity disorder (ADHD) and risk of injuries on this blog before (twice in fact, see here and see here).
The results of the systematic review and meta-analysis by Shahrokh Amiri and colleagues  (open-access hopefully available here) therefore come as little surprise: "Those with ADHD are nearly two times more likely to be injured" and necessitates only a brief blogging entry today.
Based on cumulative results - "35 studies were selected for quantitative analysis" - drawn from the peer-reviewed science literature between 2000 and 2014, something of a 'strong' association was determined between ADHD and risk of injuries.
The authors talk about how facets of ADHD might more readily predispose someone to a greater risk of injury as things like risk-taking behaviour(s) "a well-known predictor in road traffic injuries" provide an important connection, also complemented by other behaviours typically associated with ADHD. All-in-all the Amiri results again suggest that yet again, much more clinical inspection is required to (a) inform those diagnosed with ADHD about their enhanced risk, and (b) perhaps reduce the signs/symptoms and/or effects of ADHD so to modify any excess injury risk. Common sense it seems.
