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.[6][7][8][9][10][11][12][13][14]
  • 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.[15]

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.[16][15]
  • The likelihood of diagnosis is 2-3 times more in women as compared to men. [17]
  • Health care seeking behavior for symptoms is 4-5 times higher in women as compared to men.[15][17]
  • It has been postulated that the fluctuation of sex hormones in women during the menstrual cycle causing exacerbation of symptoms. [18]
  • 33 in every 100 patients have a history of sexual abuse, with women mostly as victims. [19]
  • 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.[20]

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.[21][22]
  • A greater prevalence of IBS has been found in girls worldwide.
  • In Asia, the ratio of girls affected as compared to boys is higher.[23][24]

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]
