目的:研究肠易激综合征(IBS)在地震灾区(汶川)中学教师中的患病率、发病特征、致病相关危险因素.方法:采用多级随机抽样方法,随机抽取地震灾区和非灾区3所中学269名教师进行IBS的流行病学调查.结果:校正后符合罗马Ⅱ诊断标准IBS的患病率为22.5%(95%CI:17.3%-24.7%).其中地震灾区患IBS有38例,患病率为27.9%(95%CI:20.4%-35.4%),非地震灾区患IBS有17例,患病率为15.7%(95%CI:8.8%-22.6%),经比较IBS在地震灾区的教师中患病率高于非灾区,差异有统计学意义(P<0.05);通过HAD量表调查发现,地震灾区和非灾区教师在焦虑焦虑和抑郁状况方面没有统计学意义,而患IBS教师发生率要高于非IBS教师,有统计学意义(P<0.05).结论:地震灾区教师IBS的患病率27.9%,高于非灾区教师的患病率.非灾区教师生理机能优于灾区教师,在焦虑和抑郁状况方面患IBS教师发生率要高于非IBS教师,说明地震应激事件可加重地震灾区教师的IBS发病,使其病情复杂化和治疗难度加大.
Objective: To study the prevalence, incidence characteristics and pathogenicity-related risk factors of irritable bowel syndrome (IBS) in earthquake-stricken area (Wenchuan) middle school teachers.Methods: Randomly selected multistage random sampling method The epidemiological investigation of IBS was conducted in 269 teachers in 3 middle schools.Results: The prevalence of IBS after the correction was 22.5% (95% CI: 17.3% -24.7%) according to the diagnostic criteria of Rome II, of which IBS was affected by the earthquake For example, the prevalence was 27.9% (95% CI: 20.4% -35.4%). In non-quake-hit areas, 17 were IBS with a prevalence of 15.7% (95% CI: 8.8% -22.6% The prevalence of teachers in earthquake-stricken areas was higher than that of non-disaster areas (P <0.05). According to the HAD scale survey, teachers in earthquake-affected areas and non-disaster areas did not find statistically significant anxiety, anxiety and depression, The incidence of IBS teachers was higher than that of non-IBS teachers (P <0.05) .Conclusion: The prevalence of IBS teachers in earthquake-stricken areas was 27.9%, higher than that of non-disaster area teachers.The non-disaster area teachers physiology The performance of IBS teachers in anxiety and depression was higher than that of non-IBS teachers, indicating that earthquake stress events could aggravate IBS onset disaster area teachers, making the condition more complex and difficult to treat.
