The prevalence of post traumatic stress disorder in an army unit and its relationship with functional gastrointestinal disorders / 解放军医学杂志

ABSTRACT

Objective To determine the prevalence of post traumatic stress disorder (PTSD) in the army officers and soldiers (AOSs),and identify its relationship with functional gastrointestinal disorders (FGIDs).Methods PTSD and FGIDs were diagnosed based on the PTSD checklist--civilian (PCL-C) and Rome Ⅲ Modular Questionnaire respectively,the overlaps of PTSD and FGIDs and their correlation were diagnosed.The correlation of PTSD with traumatic and stressful events was investigated using Trauma History and Stressful Event Screening Questionnaire.The coexistence and relationship of PTSD and FGIDs were analyzed.Results Of 927 AOSs,33 were diagnosed with PTSD.The prevalence of PTSD was 3.56％.FGIDs were identified in 435 subjects and the incidence of FGIDs was 46.93％.Among 33 AOSs with PTSD,28 were diagnosed as having FGIDs and the prevalence of FGIDs was 84.85％,which was significantly higher than that of non-PTSD group (45.53％,P＜0.05).Moreover,the FGIDs group had a higher prevalence of PTSD,compared with the non-FGID group (6.43％ vs.1.02％,P＜0.05).Cyclic vomiting syndrome (CVS,33.33％),unspecified functional bowel disorder (24.24％),functional bloating (18.18％) and functional anorectal pain (18.18％) were the four most frequent FGIDs in PTSD AOSs.Multiple regression analysis showed PTSD was the risk factor for CVS (OR=9.118),functional anorectal pain (OR=3.373),functional bloating (OR=4.772),irritable bowel syndrome (OR=3.438),rumination syndrome (OR=16.033),functional vomiting (OR=10.329),functional dysphagia (OR=9.891)(P＜0.05).CVS (OR=4.063),the number of traumatic (OR=1.159) and stress events (OR=1.401) were the risk factors for PTSD in AOSs (P＜0.05).Conclusions PTSD and FGID interact as risk factor each other.The prevalence of PTSD differs significantly in different FGIDs.CVS is the most frequent FGID in PTSD AOSs and risk factor for PTSD,which deserves more concerns.
