The present study investigated pubertal development in girls with maltreatment histories (N = 100), assessed at four time points over 2 years beginning in the spring of their final year of elementary school. This sample is unique, in that participants were subject to an unusual level of environmental risk early in life and resided in foster care at the start of the study. Analyses replicated the previously established association between sexual abuse and earlier onset of maturation and earlier age at menarche. Physical abuse was related to a more rapid tempo of pubertal development across the period assessed. These results strengthen previous investigations of childhood maltreatment and puberty, highlighting the complexity and specificity of early life experiences for later development.
本研究调查了有受虐史女孩(N = 100)的青春期发育情况,这些女孩从小学最后一年的春季开始,在两年内的四个时间点接受评估。该样本具有独特性,因为参与者在生命早期面临异常高的环境风险,且在研究开始时居住在寄养机构。分析结果重现了先前已确立的性虐待与青春期提前开始以及初潮年龄提前之间的关联。在评估期间,身体虐待与青春期发育节奏更快有关。这些结果强化了先前关于童年虐待与青春期的研究,突出了早期生活经历对后期发育的复杂性和特异性。
