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_age = 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.

青春期皮质醇应激反应轨迹的虐待类型差异

这项研究调查了 2002 年至 2005 年间从洛杉矶​​县招募的 454 名遭受虐待的青少年和对照青少年整个青春期的皮质醇应激反应轨迹（66.7% 遭受虐待；46.7% 女孩；39.0% 拉丁裔；37.7% 黑人；12.3% 混血或混血）混血儿；11.0% 白人；M_年龄 = 10.9 岁，SD = 1.2）。青少年的在特里尔儿童社会压力测试后计算了四波峰值激活和皮质醇反应性以及恢复斜率，然后用于模拟按年龄排列的峰值激活和皮质醇反应性以及恢复轨迹。与对照青少年相比，受虐待的青少年在 9 岁时皮质醇反应性减弱（b = −.19，p = .02)。与遭受情感虐待和忽视的青少年相比，遭受性虐待和身体虐待的青少年皮质醇反应性和恢复轨迹减弱。
