Posttraumatic Stress Disorder in a Nationally Representative Mexican Community Sample

This study describes the public health burden of trauma exposure and posttraumatic stress disorder (PTSD) in relation to the full range of traumatic events to identify the conditional risk of PTSD from each traumatic event experienced in the Mexican population and other risk factors. The representative sample comprised a subsample (N = 2,362) of the urban participants of the Mexican National Comorbidity Survey (2001−2002). We used the World Health Organization's Composite International Diagnostic Interview (CIDI) to assess exposure to trauma and the presence of PTSD according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM‐IV; American Psychiatric Association, ) in each respondents’ self‐reported worst traumatic event, as well as a randomly selected lifetime trauma. The results showed that traumatic events were extremely common in Mexico (68.8%). The estimate of lifetime PTSD in the whole population was 1.5%; among only those with a traumatic event it was 2.1%. The 12‐month prevalence of PTSD in the whole population was 0.6%; among only those with a traumatic event it was 0.8%. Violence‐related events were responsible for a large share of PTSD. Sexual violence, in particular, was one of the greatest risks for developing PTSD. These findings support the idea that trauma in Mexico should be considered a public health concern. 抽象 Traditional and Simplified Chinese s by AsianSTSS 標題：墨西哥全國代表社區樣本中的創傷後壓力症。 撮要：本研究描述在墨西哥人口中與全系列創傷事件有關的(創傷經歷和創傷後壓力症(PTSD)的)公共衛生負擔，發掘與每一創傷事件相關的PTSD條件風險和風險因素。本代表性樣本是墨西哥全國共病性調查(2001–2002)市區參與者的子樣本(N = 2,362)，採用世界衛生組織綜合國際診斷面見(CIDI) 來評估每一受訪者自我報告最惡劣創傷事件中的(第四版精神病診斷和統計學手冊(DSM‐IV))PTSD和一次隨機選出的終生創傷。結果突出墨西哥創傷事件是非常普遍(68.8%), 全民終身PTSD估算是1.5%；而有一件創傷事件經歷者為2.1%。全民12個月PTSD流行率是0.6%，而有一件創傷事件經歷者為0.8%。暴力相關事件佔了PTSD的大多數。性暴力更是發展PTSD的其中一種最高風險因素。對墨西哥而言，創傷是公共健康隱患一事，本研究提出了有力証據。 标题：墨西哥全国代表小区样本中的创伤后压力症。 撮要：本研究描述在墨西哥人口中与全系列创伤事件有关的(创伤经历和创伤后压力症(PTSD)的)公共卫生负担，发掘与每一创伤事件相关的PTSD条件风险和风险因素。本代表性样本是墨西哥全国共病性调查(2001–2002)市区参与者的子样本(N = 2,362)，采用世界卫生组织综合国际诊断面见(CIDI) 来评估每一受访者自我报告最恶劣创伤事件中的(第四版精神病诊断和统计学手册(DSM‐IV))PTSD和一次随机选出的终生创伤。结果突出墨西哥创伤事件是非常普遍(68.8%), 全民终身PTSD估算是1.5%；而有一件创伤事件经历者为2.1%。全民12个月PTSD流行率是0.6%，而有一件创伤事件经历者为0.8%。暴力相关事件占了PTSD的大多数。性暴力更是发展PTSD的其中一种最高风险因素。对墨西哥而言，创伤是公共健康隐患一事，本研究提出了有力证据。
