目的探讨空军基层部队官兵肠易激综合征(irritable bowel syndrome,IBS)的发病情况及其相关影响因素。方法采用多级、分层、整群抽样的方法对北方地区空军官兵IBS发病率进行问卷调查,按照罗马Ⅲ分类及诊断标准,对IBS进行诊断,同时对其相关影响因素进行分析。结果 IBS总患病率为15.02%;IBS分型中,IBS-C患病率最高,IBS-D次之;患病率在入伍前居住地市区(19.50%)与县城(13.62%)、农村(12.26%)比较,差异有统计学意义(P<0.05);入伍前居住在南方和边疆的官兵IBS患病率高于北方官兵;不同兵种官兵IBS患病率不一致。IBS发生与学历、吸烟、饮酒、暴饮暴食、奶制品、冷食、工作时间、过敏史、痢疾史呈正相关(γ:0.147~2.487,P=0.002~0.045);与军龄、蔬菜水果及睡眠时间呈负相关(γ:-1.439~-0.196,P=0.021~0.037)。IBS组SAS、SDS评分(51.23±9.34、54.38±8.45)均明显高于非IBS组SAS、SDS评分(37.23±7.52、38.57±9.76),差异有统计学意义(P<0.05)。结论 IBS在北方空军某部军人患病率高,其不同兵种、饮食习惯及焦虑、抑郁可能是IBS发生的重要危险因素,应采取综合措施以减少非战斗减员。
Objective To investigate the incidence and related factors of irritable bowel syndrome (IBS) in the air units of grassroots units. Methods A multi-level, stratified and cluster sampling method was used to investigate the incidence of IBS in the air force officers and soldiers in northern China. According to the classification and diagnostic criteria of Rome Ⅲ, IBS was diagnosed, and the related factors were analyzed. Results The overall prevalence of IBS was 15.02%. IBS-C was the most prevalent among IBS patients, followed by IBS-D. The prevalence of IBS-C was 19.50% in urban areas and 13.62% (12.26%) in rural areas, the difference was statistically significant (P <0.05). The prevalence of IBS among officers and soldiers living in the south and frontier areas before entering the army was higher than that of northern officers and soldiers. The prevalence of IBS in different arms was inconsistent. There was a positive correlation between IBS and education, smoking, drinking, binge eating, dairy products, cold food, working hours, allergy history and dysentery history (γ: 0.147-2.487, P = 0.002-0.045) (Γ: -1.439 ~ -0.196, P = 0.021 ~ 0.037). SAS, SDS score of IBS group (51.23 ± 9.34,54.38 ± 8.45) were significantly higher than that of non-IBS group (SDS, SDS score 37.23 ± 7.52,38.57 ± 9.76), the difference was statistically significant (P <0.05). Conclusions IBS has a high prevalence among some military personnel in the Northern Air Force. Different arms, eating habits, anxiety and depression may be important risk factors for IBS. Comprehensive measures should be taken to reduce non-combat reduction.
