海军某部官兵肠易激综合征流行病学调查及影响因素分析

An epidemiological study and risk factor analysis of irritable bowel syndrome in a Chinese naval force

目的调查我海军某部官兵肠易激综合征（IBS）患病情况并分析其可能的影响因素。方法采用多级分层随机整群抽样方法,对海军某部8600名官兵进行功能性胃肠病（FGIDs）罗马Ⅲ问卷调查,了解IBS的患病情况,同时比较罗马Ⅲ与罗马Ⅱ标准对IBS诊断的差异,并分析其相关影响因素。结果符合罗马Ⅲ标准的IBS患病率为15.91%（1205/7574）,女性患者高于男性（20.37%vs 15.73%,P=0.009）,41~45岁为发病高峰年龄,占34.6%;IBS患者以排便困难,腹胀、腹部疼痛或不适为主要症状;饮酒、经常服用药物、有痢疾史、家族史、感到疲劳等为IBS的可能影响因素。罗马Ⅱ标准的IBS患病检出率（1.75%）明显低于罗马Ⅲ标准（P=0.000）。结论我海军某部官兵IBS患病率高,应予以重视。基于罗马Ⅲ标准的患病率明显高于罗马Ⅱ标准。

Objective To investigate the prevalence and related factors of irritable bowel syndrome （IBS） in a Chinese navy unit according to Rome III classification and diagnostic criteria. Methods The questionnaire survey based on Rome III criteria was conducted in 8600 officers and soldiers in Chinese naval force using multistage, stratified, cluster random sampling method. The difference was compared in influence of the criteria on the diagnosis of IBS between Rome III and Rome i criteria. Analyses were performed for related influencing factors. Results The incidence of IBS meeting Rome Ill criteria was 15.91% （1205/7574）, and higher in female than in male （20.37% vs 15.73%, P=0.009）, and most of them were in the 41-45 year age bracket （34.6%）. Defecation difficulty, abdominal pain/discomfort and abdominal bloating were the main symptoms. Drinking, frequent drug-taking, history of dysentery, family history, and feeling of fatigue might be the most important risk factors （P〈0.01）. The incidence of IBS based on Rome II criteria was significantly lower than that of Rome llI （1.75% vs 15.91%, P=0.000）. Conclusion The incidence of IBS in Chinese naval force is high, and it should be highly regarded. Rome 1I process gives a higher incidence of IBS compared with Rome II.
