Abstract:
Objective To explore the prevalence,subtype,distribution characteristics and risk factors of IBS met ROME Ⅲ criteria in local adult residents of Shanghai Songjiang area.Methods With multi-stage,stratified cluster random sampling method,from April to May in 2010,residents of45 shanghai Songjiang communities were interviewed by questionnaire survey.IBS diagnosis was based on Rome Ⅲ criteria,and the subtypes were according to Bristol stool scale.Self-rating anxiety scale (SAS),self-rating depression scale (SDS) and Athens insomnia scale (AIS) were also simultaneously finished. Results There were 7648 individuals who completed the survey with qualified questionnaires; the efficient rate was 90％. The sample size accounted about 1.62％ of total population in Shanghai Songjiang area.Total 970 patients were detected,who met the Rome Ⅲ criteria,of those 492 males and 478 females.The adjusted prevalence of IBS was 13.1％,13.8％ in males and 12.7％ in females.The ratio of male to female was 1 ∶ 0.92.There was no significant difference in detection rate between males and females (P＞0.05).The prevalence was highest in the 18 to 29 years age group (18.2％,P=0.000).IBS unsubtyped (IBS-U) was the most common type in patients who met the Rome Ⅲ criteria (45.3 ％),IBS with diarrhea (IBS-D) type was more common in male (27.0％) and IBS with constipation (IBS-C) was more common in female (19.5％).The IBS prevalence of obesity group (x2 =4.046,P=0.044),higher education group (x2=31.210,P=0.000),mental group (x2 =8.409,P =0.015),unmarried group(x2 =26.933,P =0.000) and no abdominal surgery history group(x2 =5.894,P=0.015) was higher than that of control group.The risk of IBS prevalence in those who had the history of gastrointestinal infection,abdominal surgery,taking antibiotics or analgesics increased by 5.105,3.388,2.949 and 2.811 times respectively(P=0.000).Multivariate analysis indicated that the risk of IBS prevalence was increased by 1.69 times if took more spicy food,however high-protein diet was a protective factor (OR=0.900,P=0.000).Anxiety (OR=2.452,P=0.000) and insomnia (OR=1.923,P=0.000) were also risk factors of IBS.Conclusion IBS is a common and frequently occurring disease in Shanghai Songjiang community.The history of gastrointestinal infection,abdominal surgery,taking antibiotics or analgesics,intake of more spicy food,anxiety and insomnia may be risk factors of IBS.
