This study aimed to estimate the prevalence of symptoms of post-traumatic stress disorder (PTSD) and its association with traumatic events in a representative sample of an inner city population in the UK.
A representative community sample of 1,698 adults, aged 16 years and over, from two south London boroughs were interviewed face to face with structured survey questionnaires.
The prevalence of current symptoms of PTSD was 5.5 %. Women were more likely to screen positive (6.4 %) than men (3.6 %), and symptoms of PTSD were high in the unemployed (12.5 %), in those not working because of health reasons (18.2 %) and in the lowest household income group (14.8 %). Most (78.2 %) of the study population had lifetime trauma and more than a third (39.7 %) reported childhood trauma. There was an independent association between childhood as well as lifetime trauma and current symptoms of PTSD and a gradient association between an increase in cumulative traumatic events and the likelihood of reporting symptoms of current PTSD (OR 1.8, 95 % CI (1.6-2.1)). Although we observed the highest prevalence of current symptoms of PTSD in those migrated for asylum or political reason (13.6 %), compared to the non-migrants, the prevalence of exposure to most traumatic life events was higher in the non-migrant group.
The present study demonstrates the high prevalence of exposure to trauma in a South East London community and the cumulative effect on current symptoms of PTSD. As PTSD is a condition which is associated with disability and co-morbidity, the association of current PTSD with common adversities in the community should be noted.
本研究旨在估计创伤后应激障碍（PTSD）症状的流行率及其与英国一个内城人群中创伤事件的关联。
对来自伦敦南部两个行政区的 1698 名 16 岁及以上的代表性社区成年人进行了面对面的结构化调查问卷调查。
当前 PTSD 症状的患病率为 5.5%。女性（6.4%）比男性（3.6%）更有可能出现阳性症状，失业者（12.5%）、因健康原因无法工作者（18.2%）和收入最低的家庭（14.8%）的 PTSD 症状较高。研究人群中大多数（78.2%）有终生创伤，超过三分之一（39.7%）报告有童年创伤。童年和终生创伤与当前 PTSD 症状之间存在独立关联，累积创伤事件的增加与报告当前 PTSD 症状的可能性之间存在梯度关联（OR 1.8，95%CI（1.6-2.1））。尽管我们观察到因庇护或政治原因移民的人群中当前 PTSD 症状的患病率最高（13.6%），但与非移民相比，大多数创伤性生活事件的暴露率在非移民群体中更高。
本研究表明，在伦敦东南部社区中，创伤暴露的患病率很高，对当前 PTSD 症状有累积影响。由于 PTSD 是一种与残疾和合并症相关的疾病，因此应注意当前 PTSD 与社区中常见逆境之间的关联。
