Overview
The prevalence of diverticulosis is age-dependent. The prevalence increases from fewer than 20% at age 40 to approximately 60% by age 60. At young age (<50 years), males are more commonly affected with diverticulosis than females, but there is a female preponderance after the age of 40-50 years. Caucasian individuals are at higher risk of developing diverticulosis compared with Asian and non-African Black individuals. Diverticulosis is more commonly diagnosed in developed countries than in developing countries.
Epidemiology and Demographics
Age
- The prevalence of diverticulosis is age-dependent.
- The prevalence increases from fewer than 20% at age 40 to approximately 60% by age 60.[1][2]
Gender
- At young age (<50 years), males are more commonly affected with diverticulosis than females.
- At older age, women are more frequently affected with diverticulosis than males.[3]
Race
- There is a slight racial predilection to the development of diverticulosis.
- Caucasian individuals are at higher risk of developing diverticulosis compared with Asian and non-African Black individuals.[4]
Developed Countries
- In patients above the age of 40 years, the incidence of diverticulosis in the USA is approximately 10,000 per 100,000 individuals.
- Diverticulosis is frequently diagnosed in the US, Britain, Australia, and Canada.
- The majority of cases in developed countries are sigmoid-diverticulosis.
Developing Countries
- Diverticulosis is less commonly diagnosed in developing countries compared with developed countries.
- In Asia, the rate of right-sided diverticulosis is more common than in the developed countries, but sigmoid diverticlosis remains the most common location for diverticulosis.[5]
