Statistics by Country for Irritable bowel syndrome
|
About these extrapolations of prevalence and incidence statistics for Irritable bowel syndrome:
These statistics are calculated extrapolations of various prevalence or incidence rates
against the populations of a particular country or region.
The statistics used for prevalence/incidence of Irritable bowel syndrome are typically based on US, UK, Canadian or Australian statistics.
This extrapolation calculation is automated and does not take into account any genetic, cultural, environmental, social, racial or other differences
across the various countries and regions for which the extrapolated Irritable bowel syndrome statistics below refer to.
As such, these extrapolations may be highly inaccurate (especially for developing or third-world countries) and only give a general indication (or even a meaningless indication)
as to the actual prevalence or incidence of Irritable bowel syndrome in that region.
About prevalence and incidence statistics in general for Irritable bowel syndrome: The word 'prevalence' of Irritable bowel syndrome usually means the estimated population of people who are managing Irritable bowel syndrome at any given time (i.e. people with Irritable bowel syndrome). The term 'incidence' of Irritable bowel syndrome means the annual diagnosis rate, or the number of new cases of Irritable bowel syndrome diagnosed each year (i.e. getting Irritable bowel syndrome). Hence, these two statistics types can differ: a short disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics. |
Prevalance of Irritable bowel syndrome: 5 million in the USA 1987 (Digestive diseases in the United States: Epidemiology and Impact – NIH Publication No. 94-1447, US Government Printing Office, 1994); 11 per 1000 (NHIS95)
Prevalance Rate for Irritable bowel syndrome: approx 1 in 54 or 1.84% or 5 million people in USA [about data]
Extrapolation of Prevalence Rate of Irritable bowel syndrome to Countries and Regions: The following table attempts to extrapolate the above prevalence rate for Irritable bowel syndrome to the populations of various countries and regions. As discussed above, these prevalence extrapolations for Irritable bowel syndrome are only estimates and may have limited relevance to the actual prevalence of Irritable bowel syndrome in any region:
