某校大学生饮食习惯对肠易激综合征的影响

目的了解饮食对肠易激综合征的影响。方法对2018年10月—2019年4月来校医院就诊的1 207名在校本科生进行问卷调查,问卷依据罗马Ⅳ诊断标准,数据分析采用SPSS 22.0卡方检验、单因素分析、Logistic多因素回归分析。结果来校医院就诊的在校大学生中,肠易激综合征的患病率为5.1%(60/1207)。在单因素分析中,进食生冷(P=0.070)、高纤维(P=0.367)、乳制品(P=0.414)、果蔬(P=0.784)与肠易激综合征的患病差异无统计学意义。进食辛辣(P=0.002)、高脂饮食(P<0.001)与肠易激综合征的患病差异有统计学意义。进一步Logistic多因素回归分析显示,高频率进食高脂食物比低频率(≤1次/周)进食高脂食物更容易引起肠易激综合征。P值为0.003,OR:1.545。结论本调查样本中,肠易激综合征的患病率为5.1%。肠易激综合征的患病与进食辛辣、高脂饮食有关。高频率的进食高脂食物是肠易激综合征患病的危险因素。基层医生应着重做好相关病人的饮食指导,尽量减少肠易激综合征被诱发。

Effect of dietary habits on irritable bowel syndrome in college students of a university

Objective To investigate the effect of diet habits on irritable bowel syndrome. Methods According to Rome Ⅳ diagnostic criteria, 1 207 college undergraduates who came to the Hospital of Soochow University were investigated by the questionnaires between October 2018 and April 2019. SPSS22.0 Chi-square test, single factor analysis and Logistic regression analysis were used to analyze the data. Results The prevalence of irritable bowel syndrome was 5.1% (60/1 207) among the college students who came to the hospital. The single factor analysis showed that there were no statistically significant associations between cold (P=0.070), high-fiber (P=0.367), dairy products (P=0.414), fruits and vegetables (P=0.784) and irritable bowel syndrome, but there were statistically significant associations between spicy (P=0.002), high-fat diet (P=0.001) and irritable bowel syndrome. Further, the logistic multivariate analysis showed that high frequency consumption of high-fat food was more likely to cause irritable bowel syndrome than low frequency consumption of high-fat food, the P value was 0.003, OR: 1.545. Conclusion The prevalence of irritable bowel syndrome was 5.1% in this survey sample. The incidence of irritable bowel syndrome is related to spicy and high-fat diet. Frequent consumption of high-fat foods is a risk factor for irritable bowel syndrome. Primary doctors should focus on the dietary guidance in relevant patients to minimize the incidence of irritable bowel syndrome.
