Abstract：
This study presents findings regarding the prevalence of trauma exposure and Posttraumatic Stress Disorder (PTSD) based on discrete types of trauma (physical, sexual, witnessed violence, and non-assaultive trauma) among 3404 youth in a family study of Alcohol Use Disorder (AUD). Data from the Collaborative Study on the Genetics of Alcoholism (COGA) were used to examine associations of parent AUD with offspring\'s childhood trauma exposure, and with lifetime diagnosis of DSM-IV PTSD among White and Black participants aged 12-35. Of 3404 youth, 59.7% had parents affected by AUD and 78% experienced ≤1 traumatic events before age 18. AUD in one or both parents was associated with physical, sexual, and witnessed violence among Whites. Among African Americans, maternal AUD was associated with sexual assault. The lifetime PTSD rate among youth exposed to childhood trauma was 8.6%, and mother-only AUD was significantly associated with lifetime PTSD among participants in both groups. PTSD among youth in this study were somewhat higher (7.9% to 8.83%) than those found in general population studies of the same demographic (5% to 6.8%). Maternal AUD appears to be a salient risk factor for sexual assault before age 18 among Black and development of lifetime PTSD among White youth.
摘要：
本研究提出了基于离散类型的创伤（物理，性,目睹暴力，和非攻击性创伤）在一项关于酒精使用障碍（AUD）的家庭研究中的3404名青年中。来自酒精中毒遗传学合作研究（COGA）的数据用于检查父母AUD与后代儿童创伤暴露的关联，并在12-35岁的白人和黑人参与者中终生诊断为DSM-IVPTSD。3404青年，59.7％的父母受到AUD的影响，78％的父母在18岁之前经历了≤1次创伤事件。父母一方或双方的AUD与身体有关，性,目睹了白人之间的暴力。在非洲裔美国人中,孕产妇AUD与性侵犯有关.暴露于儿童创伤的青年的终生PTSD率为8.6％，在两组参与者中,仅母亲AUD与终生PTSD显著相关.在这项研究中，年轻人的PTSD比在相同人口统计学的一般人群研究中发现的PTSD更高（7.9％至8.83％）。产妇AUD似乎是黑人18岁之前性侵犯和白人青年终生PTSD发展的显着风险因素。
