    (Belgian Society of Paediatric Gastroenterology, Hepatology and Nutrition (BeSPGHAN),, 2013) Rajindrajith, S.; Gunawardena, N.K.; Abeygunasekara, C.; Devanarayana, N.M.
    Aims: Irritable bowel syndrome (IBS) is characterized by chronic abdominal pain and changing bowel habits including frequency and consistency. The aim of this study was to systematically review published literature on prevalence, risk factors and comorbid factors of IBS among children living in Asia. METHOD: A computer assisted search of PUB MED, CINHAL, and Index Medicus for South East Asia was carried out. Study selection criteria were; 1) Asian population based samples of children/adolescents; 2) Clear diagnostic criteria for IBS (Rome I, II or III); 3) Full manuscripts published in English. Selected articles were reviewed in depth; data were extracted and presented in descriptive form. RESULTS: Thirteen cross sectional studies which reported prevalence of IBS were included in the final analysis. Preva¬lence of IBS among Asian children and adolescents ranges from 2.8% to 25.7%. Nine studies have shown a higher prevalence of IBS in girls compared to boys. Studies from China have indicated untyped IBS as the commonest IBS subtype, while studies from Sri Lanka have shown approximately even distribution of all four subtypes. Clearly identi¬fied predisposing factors to develop IBS in Asian children included psychological stress, anxiety, depression, consump¬tion of alcohol and fatty food, smoking, and exposure to gastrointestinal infections. Comorbid factors of IBS reported among Asian children included an array of somatic symptoms, fatigue and psychological problems such as depression. CONCLUSIONS: According to published data, IBS is a significant problem among Asian children and adolescents. Female gender, exposure to stress, certain food habits, life styles and gastrointestinal infections predispose children to develop IBS in Asia.

    Epidemiology of irritable bowel syndrome in children and adolescents in Asia
    (Lippincott Williams and Wilkins, 2015) Devanarayana, N.M.; Rajindrajith, S.; Pathmeswaran, A.; Abeygunasekara, C.; Gunawardena, N.K.; Benninga, M.A.
    OBJECTIVES: Several cross-sectional surveys have been conducted to study the prevalence of irritable bowel syndrome (IBS) in children. The aim of the present 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 databases of Asia was carried out. Selected articles were reviewed in depth and data were extracted. Pooled prevalence, sex differences, and 95% confidence intervals were calculated. Heterogeneity of the studies was assessed using the I(2) test. RESULTS: A total of 16 cross-sectional studies that reported prevalence of IBS (in children and adolescents) and qualified to be included were taken into the final analysis containing 38,076 patients. 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% confidence interval 9.87-14.95). Prevalence risk ratio of girl:boy 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 sex predisposes children and adolescents to develop IBS.
