For many traits, males show greater variability than females, with possible implications for understanding sex differences in health and disease. Here, the ENIGMA (Enhancing Neuro Imaging Genetics through Meta-Analysis) Consortium presents the largest-ever mega-analysis of sex differences in variability of brain structure, based on international data spanning nine decades of life. Subcortical volumes, cortical surface area and cortical thickness were assessed in MRI data of 16,683 healthy individuals 1-90 years old (47% females). We observed significant patterns of greater male than female between-subject variance for all subcortical volumetric measures, all cortical surface area measures, and 60% of cortical thickness measures. This pattern was stable across the lifespan for 50% of the subcortical structures, 70% of the regional area measures, and nearly all regions for thickness. Our findings that these sex differences are present in childhood implicate early life genetic or gene-environment interaction mechanisms. The findings highlight the importance of individual differences within the sexes, that may underpin sex-specific vulnerability to disorders.

整个生命周期中,男性区域大脑结构的变异性大于女性



对于许多特征来说,男性比女性表现出更大的变异性,这可能对理解健康和疾病方面的性别差异产生影响。在这里,ENIGMA(通过荟萃分析增强神经影像遗传学)联盟基于跨越九个十年生命的国际数据,对大脑结构变异性的性别差异进行了有史以来最大规模的大型分析。通过 16,683 名 1-90 岁健康个体(47% 为女性)的 MRI 数据评估皮质下体积、皮质表面积和皮质厚度。我们观察到,在所有皮层下体积测量、所有皮层表面积测量和 60% 的皮层厚度测量中,男性受试者间方差大于女性。对于 50% 的皮层下结构、70% 的区域面积测量以及几乎所有区域的厚度,这种模式在整个生命周期中都是稳定的。我们的研究结果表明,这些性别差异存在于童年时期,这与早期生命的遗传或基因-环境相互作用机制有关。研究结果强调了性别内个体差异的重要性,这可能会导致特定性别对疾病的脆弱性。
