摘要目的:了解长远航官兵中功能性胃肠病（FGIDs）的发生情况及其相关影响因素。方法:选取某年执行长远航任务的某医院船307名官兵作为研究对象，采用罗马IV成人FGIDs诊断调查问卷进行调查，利用多因素Logistic回归进行相关影响因素分析。结果:共回收有效问卷300份，合格率为97.7%。长远航官兵FGIDs总发生率为11.0%（33例），其中非特异性功能性肠病发生率最高，为3.33%，其次为功能性消化不良（2.00%）、功能性便秘（1.67%）、功能性腹泻（1.33%）、恶心和呕吐症（1.33%）等。经单因素分析，性别、体质量指数、工作类型、出海次数、居住甲板位置、晕船及进食方便面与FGIDs的发生具有相关性（ P<0.05）。经多因素Logistic回归分析显示，男性是FGIDs发生的保护因素，而体质量指数的降低和频繁进食榨菜是FGIDs发生的危险因素。 结论:长远航官兵FGIDs发生率较高，其发生率与性别、体质量指数和进食榨菜相关。

abstractsObjective:To investigate the prevalence and risk factors of functional gastrointestinal disorders（FGIDs）among officers and sailors on a long oceangoing voyage.Methods:A total of 307 officers and sailors on a hospital ship undertaking a long oceangoing mission were selected as study subjects and surveyed by the Rome IV Diagnostic Questionnaire for Functional Gastrointestinal Disorders in Adults. The multivariate logistic regression was used to analyze risk factors of FGIDs.Results:A total of 300 valid questionnaires were collected，and the valid rate was 97.7%（300 / 307）. The total prevalence of FGIDs in officers and sailors on the long oceangoing mission was 11.00%（ n=33），among which the prevalence of unspecified functional bowel disorder was the highest（3.33%），followed by functional dyspepsia（2.00%），functional constipation（1.67%），functional diarrhea（1.33%），nausea and vomiting（1.33%），etc. According to the univariate analysis，gender，body mass index（BMI），type of work，times of undertaking oceangoing mission，location of berthing cabin，seasickness，and eating instant noodles were associated with the occurrence of FGIDs（ P<0.05）. The multivariate logistic regression analysis of the occurrence of FGIDs showed that the gender of male was a protective factor，while the decline of BMI and frequently eating mustard tuber were risk factors. Conclusion:The prevalence of FGIDs in officers and sailors on long oceangoing missions is relatively high，and the occurrence of FGIDs is related to gender，BMI，and eating mustard tuber.
