The features of adolescent irritable bowel syndrome in Japan
Bibliographic record
Abstract
OBJECTIVE AND BACKGROUND: The onset of IBS is in adolescence in many cases. However, the features of adolescent IBS were generally lacking. The objective of this research was to know the features of adolescent IBS in Japan. METHODOLOGY: In 2004 and 2009, we randomly selected Junior high school students in Miyagi prefecture, Japan, according to population of each area. Eight hundred thirty-three boys and 888 girls (age: 15 years old) in 2004 and 256 boys and 335 girls (age: 14 years old) in 2009 participated in this study. They fulfilled self-reported questionnaires those include Rome-II Modular Questionnaire, Self-reported IBS Questionnaire, Generalized Self-Efficacy Scale, Short Form-36 ver.2, other questions on their lives and Toronto Alexithymia Scale-20. RESULTS: The prevalence of adolescent IBS was 14.6% in 2004 and 19% in 2009. Compare with students without abdominal symptoms, IBS showed lower health-related QOL and self-efficacy and complained more sleep disturbance, traumatic episodes and perceived stress in both researches. IBS girls were worse in both physical and psychological aspects. They also have alexithymic tendency and it influenced on severity of IBS symptoms. CONCLUSIONS: Adolescent IBS had almost the same prevalence as adult IBS, however the rate of IBS subtypes was different. They also had psychological problems in addition to physical conditions even though most of them were non-consulters. Improvement of self-efficacy and alxithymia may help to prevent and treat IBS.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
