Overview
- IBS is an extremely common disorder in the population. [1][2][3][4]
- In USA and Australia, 1 in every 10 people fulfill the Rome Ⅲ criteria for IBS, although most of them tend to go undiagnosed.
- In Asian countries, IBS is underdiagnosed as risk factors for infection and dietary patterns are undergoing change.[5]
Epidemiology and Demographics
Incidence
- The incidence of IBS is approximately 200 per 100,000 individuals worldwide.[6]
Prevalence
- The worldwide prevalence of IBS is approximately 11,200 per 100,000 individuals worldwide.[7][8][6]
- The prevalence of IBS varies with geographical and demographic distribution. The prevalence of IBS in USA and Europe is 10,000-20,000 per 100,000 individuals.
Age
- The incidence of IBS decreases with age; the median age at diagnosis is 20 years.
- IBS commonly affects individuals younger than 45 years of age.
Race
- There is no racial predilection to IBS.
Gender
- Women are more commonly affected by IBS than men due to a combination of social and biological factors.[9][10]
- The likelihood of diagnosis is 2-3 times more in women as compared to men. [11]
- Health care seeking behavior for symptoms is 4-5 times higher in women as compared to men.[10][11]
- It has been postulated that the fluctuation of sex hormones in women during the menstrual cycle causing exacerbation of symptoms. [12]
- 33 in every 100 patients have a history of sexual abuse, with women mostly as victims. [13]
- Women have a lower threshold for pain and are at greater risk for development of functional and chronic pain disorders such as IBS and fibromyalgia.[14]
Children
- The prevalence of IBS in the pediatric population of different geographical settings is similar.
- In the Western pediatric population, IBS is the commonest cause of functional RAP as it accounts for more than 50% of all cases.[15][16]
- A greater prevalence of IBS has been found in girls worldwide.
- In Asia, the ratio of girls affected as compared to boys is higher.[17][18]
Region
- The majority of IBS cases are reported in USA and Australia.
- The prevalence of IBS in the pediatric population of different geographical settings is similar.
Developed Countries
- In USA and Australia, 1 in every 10 people fulfill the Rome Ⅲ criteria for IBS, although most of them tend to go undiagnosed.
Developing Countries
- In Asian countries, IBS is underdiagnosed as risk factors for infection and dietary patterns are undergoing change.[5]
