Overview
Epidemiology and Demographics
Prevalence
- The prevalence of lactose intolerance is approximately 75000 per 100,000 individuals worldwide.[1]
- In North America, the prevalence of lactose intolerance:
- Native America: 79000 per 100,000 individuals
- Black: 75000 per 100,000 individuals
- Hispanics: 51000 per 100,000 individuals
- Caucasians: 21000 per 100,000 individuals
- In Latin America, Africa, and Asia prevalence rates range from 15-100% depending on the population studied.
Age
- The prevalence of lactose intoleance are low in children younger than six years [2][3]
- The prevalence of lactose intoleance inceresed with age
Race
- Lactose intolerance usually affects individuals of the:[4][5]
- African Americans
- Hispanics
- Asians
- Asian Americans
- Native Americans
- Europeans and European Americans individuals are less likely to develop lactose intolerance.
Gender
- Lactose intolerance affects men and women equally.
Region
- The majority of lactose intolerance cases are reported in Far East.[6]
- Around the North Sea, in Northwestern Europe has the lowest prevalence of lactose intolerance.
- High rates of lactase intolerance in Africa:[7]
- Nigeria
- Malawi
- Sudan
- Ethiopia
- Uganda
- Low rates of lactose intolerance in Africa:
- Cameroon
- Mali
- South Africa
- Morocco
- Congenital lactase deficiency is a rare disease that tends to affect Finnish population.[8]
Developing Countries
- Secondary lactase deficiency is more common in children, particularly in developing countries due to high prevalence of infections. [9]
