Abstract

Objective

This study synthesized evidence regarding the prevalence of post-traumatic stress disorder (PTSD) in the United States (US).

Methods

A systematic literature review (SLR) identified recently published (2015–2019) observational studies of PTSD prevalence in the US via the MEDLINE, EMBASE, and PsycINFO databases. Eligible studies’ most recent data were collected no earlier than 2013. Data elements extracted included study design, sample size, location, data source/year(s), study population(s), traumatic event type, prevalance estimates with corresponding look-back periods, and clinical metrics.

Results

Data from 38 identified articles were categorized by population, diagnostic criteria, and lookback period. Among civilians, point prevalence ranged from 8.0% to 56.7%, 1-year prevalence from 2.3% to 9.1%, and lifetime prevalence from 3.4% to 26.9%. In military populations, point prevalence ranged from 1.2% to 87.5%, 1-year prevalence from 6.7% to 50.2%, and lifetime prevalence from 7.7% to 17.0%. Within these ranges, several estimates were derived from relatively high quality data; these articles are highlighted in the review. Prevalence was elevated in subpopulations including emergency responders, refugees, American Indian/Alaska Natives, individuals with heavy substance use, individuals with a past suicide attempt, trans-masculine individuals, and women with prior military sexual trauma. Female sex, lower income, younger age, and behavioral health conditions were identified as risk factors for PTSD.

Conclusions

PTSD prevalence estimates varied widely, partly due to different study designs, populations, and methodologies, and recent nationally representative estimates were lacking. Efforts to increase PTSD screening and improve disease awareness may allow for a better detection and management of PTSD.

美国创伤后应激障碍的患病率：系统文献综述

摘要

客观的

本研究综合了有关美国 (US) 创伤后应激障碍 (PTSD) 患病率的证据。

方法

一项系统文献综述 (SLR)通过MEDLINE、EMBASE 和 PsycINFO 数据库确定了最近发表的（2015-2019 年）美国 PTSD 患病率的观察性研究。符合条件的研究的最新数据收集时间不早于 2013 年。提取的数据元素包括研究设计、样本量、位置、数据来源/年份、研究人群、创伤事件类型、具有相应回顾的患病率估计时期和临床指标。

结果

来自 38 篇已识别文章的数据按人群、诊断标准和回顾期分类。在平民中，点患病率为 8.0% 至 56.7%，1 年患病率为 2.3% 至 9.1%，终生患病率为 3.4% 至 26.9%。在军人人群中，点患病率为 1.2% 至 87.5%，1 年患病率为 6.7% 至 50.2%，终生患病率为 7.7% 至 17.0%。在这些范围内，一些估计来自相对高质量的数据；这些文章在评论中突出显示。包括紧急救援人员、难民、美洲印第安人/阿拉斯加原住民、大量使用药物的人、有过自杀企图的人、跨性别者和曾有过军事性创伤的女性在内的亚人群的患病率有所上升。女性，收入较低，年龄较小，

结论

PTSD 患病率估计差异很大，部分原因是研究设计、人群和方法不同，而且缺乏最近的全国代表性估计。努力增加 PTSD 筛查和提高疾病意识可能有助于更好地检测和管理 PTSD。
