OBJECTIVES
We present the first review and meta-analysis of the association between adult stature and age at menarche over a broad range of human societies. We then outline possible biological explanations for observed empirical associations.
METHODS
We analyzed the association between adult stature and age at menarche in 141 samples from published reports, including 35 samples for which the within-sample association was also reported.
RESULTS
Overall and in small-scale societies, later age at menarche is associated with shorter adult stature. However, both between and within samples from industrialized societies, later age at menarche is associated with taller adult stature.
CONCLUSIONS
The pattern of associations between adult stature and age at menarche may be explicable as a norm of reaction that evolved according to predictions of life history theory. However, nonadaptive explanations are also plausible, especially for the positive association observed in industrialized societies.
目的
我们对大量人类社会中成年身高与初潮年龄之间的关系进行了首次综述和荟萃分析。然后，我们概述了观察到的经验关联的可能生物学解释。
方法
我们分析了来自已发表报告的 141 个样本中成年身高与初潮年龄之间的关系，其中包括 35 个样本报告了样本内的关联。
结果
总体而言，在小规模社会中，初潮年龄较晚与成年身高较矮相关。然而，工业化社会中的样本之间和样本内，初潮年龄较晚与成年身高较高相关。
结论
成年身高与初潮年龄之间的关联模式可以解释为根据生命史理论预测而进化的反应规范。然而，非适应性解释也是合理的，尤其是在工业化社会中观察到的正相关。
