BACKGROUND: @entity56 are an important health problem for @entity1 and adults. It is important to know how @entity56 develop and remit from infancy to adolescence. Early intervention is effective in treating @entity56 . OBJECTIVE: We performed a large-scale questionnaire survey of high school students in Fukui Prefecture, Japan, and analyzed the factors associated with the development and remission of @entity56 . METHODS: A total of 21,802 students participated in the epidemiologic survey, and the valid response rate was 89.3% (19,461). We applied an inverse probability weighting method with propensity scores. RESULTS: The present prevalence rate of @entity2023 ( @entity2023 ) was 19.2%. The remission rate of @entity2023 was 15.3%. Only @entity1 and firstborns had a significantly higher risk of developing symptoms of @entity56 [only @entity1 : @entity2023 , 1.37; @entity565 ( @entity565 ), 1.30; @entity5419 ( @entity5419 ), 1.33 and firstborn: @entity2023 , 1.38; @entity565 , 1.10]. Constipation was an associated factor for development of @entity483 ( @entity483 ) (1.17) and @entity2023 (1.17), regular intake of @entity880 bacteria was not an associated factor for development of @entity56 but was a factor for remission of @entity483 (1.22). @entity3797 was an associated factor for development of @entity483 (1.25). High academic performance was an associated factor for development of @entity2023 (1.20) but was a negative factor for development of @entity565 (0.89). The values in parentheses are significant adjusted odds ratios. CONCLUSION: This epidemiologic survey showed that the hygiene hypothesis and intestinal bacterial flora might influence the development of symptoms and remission of @entity56 .
