Abstract：
The association of post-adoption experiences of discrimination with depressive symptoms was examined in 93 previously institutionalized (PI) youth (84% transracially adopted). Additionally, we explored whether sleep quality statistically moderated this association. Notably, we examined these associations after covarying a measure of autonomic balance (high/low frequency ratio in heart rate variability) affected by early institutional deprivation and a known risk factor for depression. PI youth exhibited more depressive symptoms and experiences of discrimination than 95 comparison youth (non-adopted, NA) raised in their biological families in the United States. In the final regression model, there was a significant interaction between sleep quality and discrimination, such that at higher levels of sleep quality, the association between discrimination and depression symptoms was non-significant. Despite being cross-sectional, the results suggest that the risk of depression in PI youth involves post-adoption experiences that appear unrelated to the impacts of early deprivation on neurobiological processes associated with depression risk. It may be crucial to examine methods of improving sleep quality and socializing PI youth to cope with discrimination as protection against discrimination and microaggressions.
摘要：
在93名先前制度化的（PI）青年（84％的跨种族收养）中检查了收养后歧视与抑郁症状的关联。此外,我们探讨了睡眠质量是否在统计学上调节了这种关联.值得注意的是,我们在对受早期机构剥夺和已知抑郁危险因素影响的自主神经平衡(心率变异性的高/低频率比)的测量值进行联合校正后,研究了这些相关性.PI青年比95名比较青年表现出更多的抑郁症状和歧视经历(未采用，NA）在美国的生物家庭中长大。在最终的回归模型中，睡眠质量和歧视之间存在显著的相互作用，在更高的睡眠质量下，歧视与抑郁症状之间的关联无统计学意义.尽管是横截面，结果表明,PI青年的抑郁风险涉及收养后经历,这些经历似乎与早期剥夺对与抑郁风险相关的神经生物学过程的影响无关.研究改善睡眠质量和使PI青年社交的方法可能至关重要，以应对歧视，以防止歧视和微侵害。
