Overview

Numerous studies have reported that the prevalence of IBS varies by country and by age range examined.

Epidemiology and Demographics

The figure above shows the percentage of the population reporting symptoms of IBS in studies from various geographic regions.

Developed Countries

The following table contains a list of studies performed in different countries that measured the prevalence of IBS and IBS-like symptoms:

Percentage of Population Reporting Symptoms of IBS in Various Studies from Various Geographic Areas
Country Prevalence Author/Year Notes
Canada 6%[1] Boivin, 2001
Japan 10%[2] Quigley, 2006 Study measured prevalence of GI abdominal pain/cramping
United Kingdom 8.2%[3]

10.5%[4]

Ehlin, 2003

Wilson, 2004

Prevalence increased substantially 1970-2004
United States 14.1%[5] Hungin, 2005 Most undiagnosed
United States 15%[1] Boivin,2001 Estimate

Returning Travelers: A study of United States residents returning from international travel found a high rate of IBS and persistent diarrhea which developed during travel and persisted upon return. The study examined 83 subjects in Utah, most of whom were returning missionaries. Of the 68 who completed the gastrointestinal questionnaire, 27 reported persistent diarrhea that developed while traveling, and 10 reported persistent IBS that developed while traveling.[6]

Developing Countries

Percentage of Population Reporting Symptoms of IBS in Various Studies from Various Geographic Areas
Country Prevalence Author/Year Notes
Brazil 43%[2] Quigley, 2006 Study measured prevalence of GI abdominal pain/cramping
Mexico City 35%[7] Schmulson, 2006 n=324. Also measured functional diarrhea and functional vomiting. High rates attributed to "stress of living in a populated city."
Mexico 46%[2] Quigley, 2006 Study measured prevalence of GI abdominal pain/cramping
Pakistan 14%[8] Jafri, 2007 Much more common in 16-30 age range. Of IBS patients, 56% male, 44% female
Pakistan 34%[9] Jafri,2005 College students

Epidemiology and Demographics

  • IBS is an extremely common disorder in the population. [10][11][12]
  • 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.[13]

Incidence

  • The incidence/prevalence of [disease name] is approximately [number range] per 100,000 individuals worldwide.
  • In [year], the incidence/prevalence of [disease name] was estimated to be [number range] cases per 100,000 individuals worldwide.

Prevalence

  • The worldwide prevalence of IBS is approximately 11,200 per 100,000 individuals worldwide.[14][15]
  • 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.[16][17]
  • The likelihood of diagnosis is 2-3 times more in women as compared to men. [18]
  • Health care seeking behavior for symptoms is 4-5 times higher in women as compared to men.[17][18]
  • It has been postulated that the fluctuation of sex hormones in women during the menstrual cycle causing exacerbation of symptoms. [19]
  • 33 in every 100 patients have a history of sexual abuse, with women mostly as victims. [20]
  • 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.[21]

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.[22][23]
  • A greater prevalence of IBS has been found in girls worldwide.
  • In Asia, the ratio of girls affected as compared to boys is higher.[24][25]

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.[13]
