To explore the prevalence of irritable bowel syndrome (IBS) and its distribution characteristics of adolescents and children in China and its contributing factors. This study was a stratified, randomized study by clustering samples, which involved 5403 students whose age range was 6 to 18 years from 9 schools, and was conducted in Heilongjiang Province and Shanghai. All students studied were requested to fill in a questionnaire. IBS was diagnosed according to Rome II criteria. The prevalence of IBS according to Rome II criteria in adolescents and children in China was 13.25%. The ratio of boys to girls was 1:1.8. There was a higher prevalence (14.02%) of IBS in Heilongjiang province than that (11.72%) in Shanghai. The prevalence in children 12 years and younger was not statistically significantly higher than that of adolescents 13 years and older (11.86% and 11.44%, respectively). The prevalence of IBS in minority students (21.15%) was not statistically significantly higher than that in Han race students (16.08%). Our study indicated that psychological factors, food habit, bad exterior environment, personal habits, and family conditions might be important contributing factors, and exposure to coldness (odds ratio: 2.83) is most prominent. IBS was a common disorder in adolescents and children in China. The prevalence of IBS in adolescents and children was different in different geographic areas. Our study indicated that IBS in adolescents and children might have possible relations with psychological factors, food habit, bad exterior environment, and family condition.
    • "However, since the associations between IBS symptoms and the consumption of other staple foods with contributions to the total carbohydrate intake similar to that of buckwheat (such as Chinese noodles and bread) were dependent on carbohydrate, we consider the association of buckwheat noodles with IBS to be independent of total carbohydrate intake. It is also worth mentioning that smoking habits did not show any association with IBS prevalence in this study, although the negative role of current smoking in IBS prevalence has been reported by other population-based studies [32, 33]. Meanwhile, association between staple foods and IBS prevalence was not affected by adjustment for smoking status in multivariate analysis, suggesting the observed association between several staple foods and IBS prevalence in this study is not mediated by smoking habits.

    [Show abstract] [Hide abstract] ABSTRACT: Carbohydrates can cause gastrointestinal symptoms due to incomplete absorption in the small bowel. Thus, high-carbohydrate diets may induce symptoms of irritable bowel syndrome (IBS). This observational and cross-sectional study assessed the association between consumption of several carbohydrate-enriched staple foods, such as rice, Japanese wheat noodles, Chinese noodles, bread, pasta, and buckwheat noodles, and the prevalence of IBS in Japanese adults. One thousand and eighty-two (837 men) Japanese adult employees aged 19-85 were included in this cross-sectional study conducted in 2011. IBS diagnosis was based on the Rome III criteria. Consumption of staple foods was assessed using a brief self-administered diet history questionnaire, and divided into three categories (low, middle, high) depending on their distribution. In the multivariate analysis, daily consumption of rice (odds ratios [ORs] and [95% confidence interval (CI)]: middle, 1.36 [0.93-1.99]; high, 1.67 [1.12-2.49]; P for trend = 0.01), bread (middle, 1.88 [1.28-2.75]; high, 1.63 [1.10-2.41]; P for trend = 0.01), pasta (middle, 1.47 [1.01-2.15]; high, 1.68 [1.12-2.52]; P for trend = 0.01), and buckwheat noodles (middle, 1.76 [1.18-2.61]; high, 1.98 [1.31-3.00]; P for trend = 0.001) were associated with higher prevalence of IBS after adjustment for socio-demographic, anthropometric, and lifestyle-related factors. Buckwheat noodles, but not other staple foods, retained an association with the prevalence of IBS even after adjustment for daily intake of carbohydrates or plant proteins. This cross-sectional study demonstrated that the consumption of staple foods, such as rice, bread, pasta, and buckwheat noodles is associated with the prevalence of IBS. Of these, the consumption of buckwheat noodles, but not other staple foods, is associated with IBS independent of carbohydrate or plant protein contents.

    • "They range from 6 to 19 years, and the majority included children in their teens. Only 5 studies reported age-specific prevalence (6,16,19,26,29). According to them, prevalence seems to be increasing with age. "
    [Show abstract] [Hide abstract] ABSTRACT: Background and aims: Several cross sectional surveys have been conducted to study the prevalence of irritable bowel syndrome (IBS) in children. The aim of this study was to conduct a systematic review and a meta-analysis of published literature to estimate the prevalence of IBS among Asian children. Method: A computer assisted search of MEDLINE, EMBASE, psycINFO and regional data bases of Asia was carried out. Selected articles were reviewed in depth and data were extracted. Pooled prevalence, gender differences as well as 95% confidence intervals were calculated. Heterogeneity of the studies was assessed using I 2 test. Results: Sixteen cross sectional studies which reported prevalence of IBS (in children and adolescents) and qualified to be included, were taken into the final analysis containing 38,076 subjects. Selected studies are from China, Korea, Japan, Iran, Sri Lanka, and Saudi Arabia. Studies showed a marked heterogeneity with I 2 of 98.59 (p < 0.0001). Prevalence of IBS ranges from 2.8% to 25.7%, with a pooled prevalence of 12.41% (95% CI 9.87-14.95%). Prevalence risk ratio of female: male is 1.39. Prevalence of subtypes is diverse and varies between studies. Conclusions: The published data indicate that IBS is a significant problem among Asian children and adolescents. Female gender predisposes children and adolescents to develop IBS.

    • "However, in our cohort, this was not the case. In fact, insomnia was significantly more prevalent with abdominal migraine than with the other subtypes of abdominal pain-predominant FGID [31]. This study also demonstrated the impact of IBS on school attendance of affected children. "
    [Show abstract] [Hide abstract] ABSTRACT: Abstract Background: Recurrent abdominal pain (RAP) is a common complaint in children. Significant portion of them are of functional origin. This study aimed to assess the prevalence of abdominal pain predominant functional gastrointestinal disorder (FGID) and its types in Jordanian school children. Methods: This is a school-based survey at south Jordan. Information using the self-reporting form of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version (QPGS-RIII) - the official Arabic translation - was collected. Classes from academic years (grades) 6 - 8 were selected. SPSS Statistical Package Version 17 (IBM, Armonk, NY, USA) was used. Categorical data were analyzed using Fisher’s exact test, and continuous data were analyzed using t-test. P < 0.05 was considered significant. Results: Five hundred questionnaires were distributed, and 454 returned answered (91%). Two hundred twenty-nine (50.8%) were males. The average age of participants was 12.7 years (11 - 15 years). One hundred sixteen (25.7%) had abdominal pain-predominant FGID. Seventy-nine (68%) of them were females. Forty-seven (10.6%) had irritable bowel syndrome (IBS). Thirty-six (8%), 17 (3.8%), 11 (2.4%) and five (1.1%) had abdominal migraine, functional abdominal pain, functional abdominal pain syndrome and functional dyspepsia, respectively. Conclusion: Abdominal pain-predominant FGID has become a major health issue in Jordanian children. One of four children between the ages of 11 and 15 years exhibits at least one abdominal pain-predominant FGID. The most common form of abdominal pain-predominant FGID in our children was IBS. Females are affected more often than males. Intestinal and extra-intestinal symptoms are seen regularly with abdominal pain-predominant FGIDs.
