■联合国特派团的维持和平人员经历了潜在的创伤事件,导致创伤后应激障碍(PTSD)的风险增加。了解PTSD症状严重程度的过程和危险因素对于确保人员安全至关重要。
■为了调查创伤后应激障碍的发生率,症状严重程度轨迹,以及与部署在南苏丹的日本维和人员的不利轨迹相关的潜在风险因素。
■这项为期6年的前瞻性队列研究的数据是从2011年12月至2018年12月从部署在联合国南苏丹特派团的日本地面自卫队人员收集的。对应于部署前和部署后78个月。在3799名潜在参与者中,80人由于多次部署而被排除在外,757人由于缺少数据而被排除在外,不完整的回答,或不提供知情同意。因此,2962名参与者被纳入分析。从2022年2月至2024年2月进行数据分析。
■参与者被派往联合国南苏丹特派团6个月。
■修订的22项事件影响量表用于评估PTSD症状,有25个或更多的点表示可能的PTSD(p-PTSD)。收集了社会人口统计数据,并在部署前进行30项一般健康问卷,以确定PTSD症状严重程度的危险因素。
■在研究的2962名参与者中(男性2901[97.9%];平均[SD]年龄,33.9[7.2]年),p-PTSD的发生率为3.95%.潜在生长混合模型确定了4种症状严重程度轨迹:弹性(2143[72.3%]),回收率(479[16.2%]),旷日持久(182[6.1%]),并延迟(158[5.3%])。多项logistic回归显示,睡眠障碍是2种最严重轨迹的常见危险因素(延长:优势比[OR],1.29;95%CI,1.08-1.54;延迟:OR,1.26;95%CI,1.03-1.53),而年龄较大(或,1.25;95%CI,1.06-1.48),焦虑和烦躁不安(或,1.45;95%CI,1.20-1.75),和一般疾病(或,1.30;95%CI,1.06-1.59)与延长的轨迹相关。
■这项队列研究发现,大约4%的参与者出现了p-PTSD,并确定了4种不同的PTSD症状轨迹。研究结果表明,解决睡眠障碍和一般健康问题可以有效预防维和人员的PTSD症状。
UNASSIGNED: Peacekeepers in United Nations missions experience potentially traumatic events, resulting in increased risk for posttraumatic stress disorder (PTSD). Understanding the course and risk factors of PTSD symptom severity is crucial to ensure personnel safety.
UNASSIGNED: To investigate the incidence of PTSD, symptom severity trajectories, and potential risk factors associated with adverse trajectories among Japanese peacekeepers deployed in South Sudan.
UNASSIGNED: Data for this 6-year prospective cohort study were collected from December 2011 to December 2018 from Japan Ground Self-Defense Force personnel deployed at the United Nations Mission in South Sudan, corresponding to before and up to 78 months after deployment. Of 3799 potential participants, 80 were excluded because of multiple deployments and 757 because of missing data, incomplete responses, or not providing informed consent. Therefore, 2962 participants were included in the analysis. Data analysis was performed from February 2022 to February 2024.
UNASSIGNED: The participants were deployed to United Nations Mission in South Sudan for 6 months.
UNASSIGNED: The 22-item Impact of Event Scale-Revised was used to assess PTSD symptoms, with 25 or more points indicating probable PTSD (p-PTSD). Sociodemographic data were collected, and the 30-item General Health Questionnaire was administered before deployment to identify risk factors for PTSD symptom severity.
UNASSIGNED: In the 2962 participants studied (2901 [97.9%] male; mean [SD] age, 33.9 [7.2] years), the incidence of p-PTSD was 3.95%. Latent growth mixture models identified 4 symptom severity trajectories: resilient (2143 [72.3%]), recovery (479 [16.2%]), protracted (182 [6.1%]), and delayed (158 [5.3%]). Multinomial logistic regression showed that sleep disturbance was a common risk factor for the 2 most severe trajectories (protracted: odds ratio [OR], 1.29; 95% CI, 1.08-1.54; delayed: OR, 1.26; 95% CI, 1.03-1.53), whereas older age (OR, 1.25; 95% CI, 1.06-1.48), anxiety and dysphoria (OR, 1.45; 95% CI, 1.20-1.75), and general illness (OR, 1.30; 95% CI, 1.06-1.59) were associated with the protracted trajectory.
UNASSIGNED: This cohort study found that approximately 4% of the participants developed p-PTSD and identified 4 distinct PTSD symptom trajectories. The findings suggest that addressing sleep disturbance and general health issues could effectively prevent PTSD symptoms among peacekeepers.
