某部新兵肠易激综合征的流行病学调研

目的调研某部新兵肠易激综合征的患病率及危险因素。方法按罗马Ⅲ标准制订表格，用多级分层随机整群抽样方法，对某部新兵17～19岁2188人进行问卷调查，对有症状者进行结肠镜或结肠气钡造影排除结肠器质性疾病，得出患病率。对患病有关的危险因素作单因素和多因素分析。结果某部新兵符合罗马Ⅲ标准的患病率为15．27％，分层研究表明患病率在城市（18．32％）和农村（13．78％）差异显著（P〈0．05）；患病与文化程度存在一定关系，高中学历（X^2=8．67）和中专、初中学历（X^2=4．67）差异显著（P〈0．05）。经多因素回归分析，家族史、紧张疲劳、痢疾肠炎史、饮酒、抑郁为最可能性的危险因素。结论肠易激综合征是某部新兵的常见病，病因较明确，部队人员应提高对该病的认识，加强防治工作。

Epidemiological Investigation of Irritable Bowel Syndrome in Recruits

Objective To investigate the prevalence rate and risk tactors of irritable bowel syndrome （IBS） in recruits. Methods The investigation schedules followed Rome Ⅱ criteria were used to collect the data of 2 188 recruits with ages from 17-19 years. Colonoscopy or barium enema was performed in the patients in order to exclude organic diseases, and to calculate prevalence rate. Univariate and multivariate analyses of the risk factors related to prevalence were performed. Results The prevalence rate of IBS in the recruits of investiga- tion was 15.27% according to Rome Ⅲ criteria. Further investigation showed that recruits from downtown （18. 32%） had higher prevalence rate than that from rural area（13.78~/Q） with significant difference（P（0.05）. Education background was another important factor. High school eduction（x^2=8.67） offered higher prevalence rate than that of middle school education （X^2 = 4.67） with significant difference（P〈0.05）. In multivariable regression analyses, family history, tense fatigue, history of diarrhea, excessive drinking and depression were most important risk factors. Conclusion The prevalence rate of IBS in recruits investigated was still high. The causes of pathogenesis were clear.
