Overview
The prevalence of diverticulitis is 20,000 individuals at age 40 and 60,000 at age 60. The highest incidence is in patients between 18 to 44 years old. Men and women are equally affected by diverticulitis between 50-70, but men above 70 are more commonly affected than women. The prevalence of diverticulitis has increased in developed countries. In the United States, approximately 312,000 cases are admitted to the hospitals. In Japan, more cases of right side diverticulitis have been reported than cases of left side diverticulitis.
Epidemiology and Demographics
Prevalence
The prevalence of diverticulitis is 20,000 individuals at age 40 and 60,000 at age 60.
Age
- The prevalence of diverticulitis increases with age.
- The mean age at admission for acute diverticulitis is 63 years.[1]
Gender
- Men under 50 are more often affected by diverticulitis than women of the same age.
- Men and women aged 50-70 are equally affected by diverticulitis.[2]
- Men over 70 are more often affected by diverticulitis than women of the same age.[3][4]
Race
- There is no racial predilection for diverticulitis.
Developed countries
- The prevalence and incidence of diverticulitis have significantly increased in developed countries that consume a lot of Westernized food that is poor in fiber.
- In the United States, about 312,000 cases of diverticulitis are admitted to hospitals.
- In Japan, there has been an increase in the prevalence of right-sided diverticulosis similar to the increase in left-sided diverticula in Westernized countries.[5][6]
