中国汶川地震现场救援军人创伤后应激障碍及相关因素的调查

目的 调查抗震救灾一线救援军人任务完成6个月创伤后应激障碍(PTSD)的患病率及相关因素.方法 采用目前美国PTSD流行病学调查和诊断工具,按整群分层抽样原则对1125名汶川抗震救灾现场救援军人PTSD的患病率及相关因素进行调查.PTSD诊断采用Davidson创伤量表(DTS)症状发生频率和严重程度总分≥40分标准确定,并使用美国精神障碍诊断与统计手册第4版(DSM-Ⅳ)诊断标准复查,使用SPSS13.0软件对调查资料和DTS诊断结果进行单因素和Logistic回归分析.结果 实际调查1056人;DTS诊断PTSD 69例,患病率6.53%;DSM-Ⅳ复查符合诊断63例,患病率5.97%;独生子女、服役满意度低、吸烟、创伤暴露阶段未进行心理干预及有饮酒习惯者PTSD患病率显著高于相对应的人群(P＜0.05);地震经历暴露程度高(P＜0.01,OR=6.258)、创伤暴露阶段未进行心理干预(P=0.019,OR=3.106)是抗震救灾现场救援军人PTSD的显著危险因素,而独生子女是PTSD潜在的危险因素(P=0.057,OR=2.235).结论 PTSD是抗震救灾现场军人常见的心理障碍,加强创伤暴露者的心理防护和危机干预十分必要.

The prevalence of post traumatic stress disorder and impact factors in military first responders 6 months after Wenchuan earthquake in China

Objective To determine the prevalence of post-traumatic stress disorder (PTSD) and its impact factors 6 months after Wenchuan earthquake in a group of military first responders.Method A total of 1125 military first responders serving in the earthquake were screened and enrolled in the study.The social-demographic characteristics, Davidson Trauma Scale ( DTS), earthquake exposure screening scale, Beck Anxiety Inventory (BAI) and Beck Depression Inventory ( BDI- Ⅱ ) were assessed to every first responder 6 months after the earthquake.The PTSD diagnosis was based on both DTS ≥ 40 and DSM-Ⅳ criteria.Results The final analysis was carried out on 1056 first responders.The prevalence of PTSD was 6.53% (69 cases) according to DTS criteria and 5.97% (63 cases) according to DSM-Ⅳ criteria.The univariate analysis revealed that being a single child, dissatisfied with current service, having a history of smoking or drinking, no psycho counseling during traumatic exposure and intensity of traumatic exposure were significantly associated with an increased risk of PTSD.Results from logistic regression indicated that the intensity of traumatic exposure, no psycho counseling during traumatic exposure were significant predictors of PTSD.Being a single child (OR =2.24, 95% CI 0.98 -5.12,P =0.057) was a trend predictor of PTSD.Conclusion The study results support that PTSD is a common mental disorder in military first responders earthquake, it is necessary to strengthen psychological protection and crisis intervention.
