This study tested the theory that left-handedness is associated with certain disorders that may have an autoimmune aetiology. To accomplish this, we compared the handedness patterns of people with either Type I or Type II diabetes, Crohn's disease, or ulcerative colitis with a normal control group. Consistent with earlier findings, a significantly higher incidence of left-handedness was observed in people with either Crohn's disease or ulcerative colitis. In addition, there was evidence that males with Type I diabetes were more likely to be left-handed than males with Type II diabetes.
本研究检验了一种理论，即左利手与某些可能具有自身免疫病因的疾病有关。为了实现这一目标，我们将患有I型或II型糖尿病、克罗恩病或溃疡性结肠炎的人群的利手模式与正常对照组进行了比较。与早期研究结果一致，在患有克罗恩病或溃疡性结肠炎的人群中观察到左利手的发生率显著更高。此外，有证据表明，患有I型糖尿病的男性比患有II型糖尿病的男性更有可能是左利手。
