Risk factorsBy Mayo Clinic Staff
Some known risk factors for type 1 diabetes include:
- Family history. Anyone with a parent or sibling with type 1 diabetes has a slightly increased risk of developing the condition.
- Genetics. The presence of certain genes indicates an increased risk of developing type 1 diabetes.
- Geography. The incidence of type 1 diabetes tends to increase as you travel away from the equator. People living in Finland and Sardinia have the highest incidence of type 1 diabetes — about two to three times higher than rates in the United States and 400 times the incidence among people living in Venezuela.
- Age. Although type 1 diabetes can appear at any age, it appears at two noticeable peaks. The first peak occurs in children between 4 and 7 years old, and the second is in children between 10 and 14 years old.
Many other possible risk factors for type 1 diabetes have been investigated, though none have been proved. Some other possible risk factors include:
