Abstract

過敵性腸症候群(IBS)は思春期に多い症候群であるが,その特徴はいまだ十分明らかではない.今回われわれは,高校生IBSの精微の把握を目的にアンケート調査を行った.男子1,150人中107人(9%),女子273人中46人(17%)がRomeIIのIBS診新基準を満たした(IBS群).腹部症状のない生徒(対照群)や腹部症状があっても診新基準を満たさない生徒(FBD群)と比較すると,IBS群は健康関連QOLが低く,自己効力感も低かった.IBS群の大部分に頻回の腹痛と軟〜水様側を認めた.排便後の腹部症状終決は男子IBS群に多く,粘液の付着,腹部膨満感,予期不安,行動制限,ストレス下のIBS症状増悪は有意に女子IBS群に多かった.重症度を反映するIBSスコアは,女子IBS群のほうが高かった.わが国の思春期IBSの有症候率は成人と変わらないが,性差,サブタイプの割合など成人とは異なる持徴が認められた.

Background : The number of adolescent IBS may be increasing in Japan. However, the prevalence and the characteristics of them are unclear because most of them don't consult medical care. The objective of this research was to know the characteristics of high school students with IBS in Japan. Methods : High school students(1,150 boys and 273 girls)(age : 16-18 y.o.) fulfilled self-reported IBS questionnaires, Generalized Self-Efficacy Scale(OSES) and SF-36. Results : One hundred and seven boys(9%) and 46 girls(17%) were diagnosed as IBS based on Rome II criteria. IBS students had lower scores in all SF-36 subscales and GSES than controls(boys : 495, girls : 61) and functional bowel disorder(FED) students(boys : 548, girls : 166) whose abdominal symptoms didn't satisfy IBS Rome II criteria. Over 80% of IBS students had frequent abdominal pain and complained loose/watery stool with abdominal pain or discomfort. Relief of abdominal symptoms with defecation was seen more frequently in boys(p<0.05). On the other hand, passing mucus(p<0.0001), abdominal fullness(p<0.01), anticipatory anxiety(p<0.05), limitations of daily activity(p<0.005), exaggeration of IBS symptoms under stress(p<0.0005), laxative use(p<0.0001) were seen more frequently in girls. Many IBS students complained that they could not go to school and/or somewhere they could not find rest rooms easily. IBS scores that reflect severity of IBS symptoms were also significantly higher in girls(p=0.001). There was no difference in scores of GSES between boys and girls. Conclusion : Prevalence of high school students IBS in Japan was similar to that of adult, but they had some different characteristics from adults.
