This study examined cortisol stress response trajectories across adolescence in 454 maltreated and comparison youth recruited from Los Angeles County between 2002 and 2005 (66.7% maltreated; 46.7% girls; 39.0% Latino; 37.7% Black; 12.3% Mixed or Biracial; 11.0% White; M = 10.9 years, SD = 1.2). Adolescents' peak activation and cortisol reactivity and recovery slopes following the Trier Social Stress Test for Children were calculated at four waves, then used to model peak activation and cortisol reactivity and recovery trajectories arrayed by age. Maltreated youth had blunted cortisol reactivity at age 9 relative to comparison youth (b = -.19, p = .02). Sexually and physically abused youth showed blunted cortisol reactivity and recovery trajectories relative to emotionally abused and neglected youth.
这项研究在 2002 年至 2005 年期间，从洛杉矶县招募了 454 名受虐待和对照组的青少年（66.7%受虐待；46.7%为女孩；39.0%拉丁裔；37.7%黑人；12.3%混合或多种族裔；11.0%白人；M=10.9 岁，SD=1.2 岁），考察了他们在整个青春期的皮质醇应激反应轨迹。在四次波次中，计算了青少年在儿童特里尔社会压力测试后的峰值激活和皮质醇反应性以及恢复斜率，然后用于根据年龄排列峰值激活和皮质醇反应性及恢复轨迹。与对照组相比，在 9 岁时，受虐待的青少年皮质醇反应性减弱（b=-.19，p=.02）。性虐待和身体虐待的青少年与情感虐待和忽视的青少年相比，皮质醇反应性和恢复轨迹减弱。
