Abstract

Approximately 10% of the global population is left-handed. Much research has been directed at handedness and health, with reports of left-handers suffering higher rates of numerous health conditions, accidents, injuries and ultimately, significantly reduced lifespans. Most previous research focused on 'well' or general-population samples; no previous investigations of the effects of handedness on injecting drug users' (IDUs) health are known. Aim: To investigate associations between handedness and health outcomes among IDUs-a marginalized population subgroup with significantly worse health than average. Methods: A total of 346 self-identified left- (9.5%) or right-handed current IDUs were re..
