在参考样本和研究确定的样本中，阅读困难的患病率通常男性高于女性，而且在受影响较大的样本中，男性与女性的比例更高。为了探索阅读成绩上可能存在的性别差异，我们分析了1133对双胞胎的数据，每对双胞胎中至少有一人有阅读问题的在校历史，以及684对双胞胎的数据，这些双胞胎来自没有阅读困难的对照样本。尽管这两个样本中男性和女性的平均分数差异很小，但两组男性阅读成绩的差异明显更大。我们认为，男性阅读成绩指标的较大差异可能至少在一定程度上解释了他们阅读困难的发生率较高，以及在更严重受损的样本中观察到的较高的性别比例。版权所有(C)2009 John Wiley&Sons，Ltd.
The prevalence of reading difficulties is typically higher in males than females in both referred and research-identified samples, and the ratio of males to females is greater in more affected samples. To explore possible gender differences in reading performance, we analysed data from 1133 twin pairs in which at least one member of each pair had a school history of reading problems and from 684 twin pairs from a comparison sample with no reading difficulties. Although the difference between the average scores of males and females in these two samples was very small, the variance of reading performance was significantly greater for males in both groups. We suggest that a greater variance of reading performance measures in males may account at least in part for their higher prevalence of reading difficulties as well as for the higher gender ratios that are observed in more severely impaired samples.
