机构照料中的幼儿所经历的条件与他们对依恋关系的需求是不相容的。因此，早期制度化有望对下丘脑-垂体-肾上腺皮质（HPA）轴的调节产生持久的影响。目前的研究测试了130名年龄在6至48个月之间被国际收养的儿童的早期机构是否对每日HPA轴结果有持续的影响。每天在两个时间点收集儿童的皮质醇样本：收养后不久（平均收养后5.3个月）和大约3年后（平均收养后39.2个月）。在被收养后不久，经历过长时间机构照顾的儿童比那些经历过很少或没有机构照顾的儿童早上的皮质醇水平更低，皮质醇在一天中的下降幅度更大。三年后，经历过长时间机构化的儿童继续表现出较低的早晨皮质醇水平，也表现出较低的睡前皮质醇水平。总之，这些结果支持了早期逆境导致HPA轴下调的观点，并表明制度化对HPA轴功能的影响可能在儿童被收养到高度富裕的家庭后持续数年。
Young children in institutional care experience conditions that are incompatible with their needs for attachment relationships. As a result, early institutionalization is expected to have lasting effects on the regulation of the hypothalamic–pituitary–adrenocortical (HPA) axis. The current study tested whether early institutionalization has persistent consequences for diurnal HPA axis outcomes among 130 children who had been adopted internationally between the ages of 6 and 48 months. Daily cortisol samples were collected from children at two time points: shortly after adoption (average of 5.3 months after adoption) and approximately 3 years later (average of 39.2 months after adoption). Shortly after adoption, children who had experienced a long duration of institutional care had lower morning cortisol levels and more blunted declines in cortisol across the day than children who experienced minimal or no institutional care. Three years later, children who had experienced a long duration of institutionalization continued to exhibit low morning cortisol levels and also exhibited low bedtime cortisol levels. Altogether, these results support the idea that early adversity results in the downregulation of the HPA axis and suggest that the effects of institutionalization on HPA axis functioning may persist several years after children are adopted into highly enriched families.
