广东省社区人群肠易激综合征的流行病学研究

目的　探讨广东省社区人群肠易激综合征 (IBS)的患病率及危险因素。方法　用整群、分层、随机抽样的方法在广东省内对广州市、惠州市及惠阳县马安镇 (代表农村 )三地的常住人口中 18～ 80岁的居民进行面访式问卷调查作为初查 ,了解按Manning标准加以补充 (含便秘症状 )及罗马Ⅱ(RomeⅡ )标准的IBS的患病率和危险因素。结果　 (1)共调查 4 178人 ,其中男 190 7人 ,女 2 2 71人 ,平均年龄 (43± 14 )岁 ,应答率为 98% ;(2 )广东省有症状符合RomeⅡ标准的IBS的标化患病率为5 6 7% ,符合Manning标准的IBS的标化患病率为 11 5 0 % ,患病率无城乡和年龄差别 ,男女患病率之比分别为 1∶1 2 5 (按RomeⅡ标准 )和 1∶1 34(按Manning标准 ) ;(3)经单因素和多因素回归分析 ,服非甾体类抗炎药 (NSAID) (OR =3 83)、食物过敏史 (OR =2 6 8)、心理障碍性疾病 (OR =2 18)、生活事件(OR =1 89)、肠炎或痢疾史 (OR =1 6 3)及消极应对方式 (OR =1 2 8)等为最可能的危险因素。结论　IBS是广东省的常见病 ,应引起重视 ;食物过敏史等为最可能的危险因素 ,值得进一步研究。

A population-based epidemiologic study of irritable bowel syndrome in Guangdong province

OBJECTIVE: To explore the prevalence of irritable bowel syndrome (IBS) and its risk factors in Guangdong province. METHODS: A questionnaire was used to screen IBS by face-to-face interviews according to Manning (modified including symptoms of constipation) and Rome II criteria. Random clustered sampling involving permanent inhabitants aged 18 - 80 years was carried out under stratification of urban and suburban areas. Potential risk factors were explored by comparing the frequencies among IBS group and non-IBS group using chi(2) and logistic analysis of multivariate adjusted for age and gender. RESULTS: A total of 4178 residents (male 1907, female 2271) were investigated. Mean age among the responders was (43 +/- 14) years. The response rate was 98%. The adjusted prevalence of IBS in Guangdong province is 5.67% according to the modified Rome II criteria, and is 11.50% according to Manning criteria. There is no difference between urban and suburban areas. The female was predominant in IBS, and the ratio of male to female was 1:1.25 (Rome II) and 1:1.34 (Manning). The age was poorly correlated with the prevalence. Events including history of analgesic use such as NSAID (OR = 3.83), history of food allergies (OR = 2.68), psychological distress (OR = 2.18), life events (OR = 1.89), history of dysentery (OR = 1.63) and negative coping style (OR = 1.28) are highly associated with IBS (P < 0.05). CONCLUSION: IBS is a common disorder in Guangdong Province which deserves greater care and further investigation.
