Epidemiology and Demographics
Diverticulitis most often affects middle-aged and elderly persons, though it can strike younger patients as well.[1] Abdominal obesity may be associated with diverticulitis in younger patients, with some being as young as 20 years old.[2]
In Western countries, diverticular disease most commonly involves the sigmoid colon - section 4 - (95% of patients). The prevalence of diverticular disease has increased from an estimated 10% in the 1920s to between 35 and 50% by the late 1960s. 65% of those currently 85 years of age and older can be expected to have some form of diverticular disease of the colon. Less than 5% of those aged 40 years and younger may also be affected by diverticular disease.
Left-sided diverticular disease (involving the sigmoid colon) is most common in the West, while right-sided diverticular disease is more prevalent in Asia and Africa. Among patients with diverticulosis, 10-25% patients will go on to develop diverticulitis within their lifetimes.
Peanuts and seeds may aggravate diverticulitis.[3]
Prevalence
The prevalence of diverticulosis is age-dependent, increasing from less than 20 percent at age 40 to 60 percent by age 60. The mean age at admission for acute diverticulitis is 63 years.[4][5]
Incidence=
The incidence of diverticulitis is increasing.The largest increase was in patients aged 18 to 44 years.[6]
Case fatality rate
Age
The prevalence of diverticulitis increases with age.
Gender
- Men under 50 are more commonly affected by diverticulitis.
- Men and women aged 50-70 are equally affected by diverticulitis.[7]
- Men aged greater than 70 are more affected by diverticulitis.[8][9]
Race
There is no racial predilection for diverticculitis.
Developed countries
The prevalence and incidence of diverticulitis has significantly increased in developed countries that consume a lot of westernized food that is poor in fiber. For example Japan has experienced an increase in the prevalence of right-sided diverticulosis similar to the increase in left-sided diverticula in westernized countries.[10][11]
