Diabetes in children is, in more than 95% of cases, type 1 diabetes.
The current epidemiological data on the proportion/prevalence of type 1 diabetes in children and adolescents (<20 years) in Germany, Europe, America (particularly the USA), and India, based on available epidemiological sources. Wherever possible, prevalence rates per 100,000 or per 1,000 children are used, as these allow better standardized comparisons than absolute numbers.
Germany (children and adolescents)
Prevalence (proportion of children with type 1 diabetes)
• In 2022, approximately 34,600 children and adolescents aged 0–17 years had type 1 diabetes, corresponding to a prevalence of about 243 per 100,000 (0.243%) in this age group.
This means roughly 243 out of 100,000 children/adolescents live with type 1 diabetes.
Estimate per 1,000 children
• Converted: approximately 2.43 per 1,000 children/adolescents.
Europe (overall)
For the European continent as a whole, there are no uniform, up-to-date prevalence percentages. However, international epidemiological studies show:
European prevalence/incidence patterns
• The prevalence and incidence of type 1 diabetes in children vary widely across Europe. In several countries, prevalence rates range from approximately 20 to 70 cases per 100,000 children in the studied age groups (0–14 years).
An important note is the large regional variation within Europe. Northern European countries (e.g., Scandinavia) show substantially higher rates than southern regions.
America (particularly the United States)
USA – prevalence among children/adolescents (<20 years)
• Estimates from the United States indicate that approximately 215 cases per 100,000 children and adolescents (<20 years) have type 1 diabetes.
This corresponds to roughly 2.15 per 1,000 children/adolescents.
Absolute numbers (as of 2021)
• About 304,000 children and adolescents in the United States have diagnosed type 1 diabetes (out of approximately 352,000 diabetes cases in this age group).
India (children)
For India, comprehensive nationwide prevalence data are far more limited compared with Europe or North America. Available epidemiological studies indicate:
India – local prevalence data (regional variability)
• Reported prevalence varies considerably by region:
These figures indicate that childhood type 1 diabetes prevalence in India is generally low (<20 per 100,000), with substantial regional differences and dependence on diagnostic coverage.
IDF Atlas estimates
• According to the Type 1 Diabetes Index/IDF Atlas, the per-capita prevalence of type 1 diabetes among children and adolescents (0–19 years) in India is markedly lower than in Europe or North America, although absolute numbers are high due to population size (e.g., >200,000 children with T1D).
Summary – comparison of prevalence rates in children (<20 years)
Region | Prevalence (children with T1D) | Equivalent to |
Germany | ~243/100,000 | ~2.43/1,000 |
Europe (overall) | Variable ≈ 20–70/100,000 | ≈0.20–0.70/1,000 |
USA (America) | ~215/100,000 | ~2.15/1,000 |
India | ~3.2–17.9/100,000 (regional) | ~0.03–0.18/1,000 |
Interpretation
Notes on interpretation:
Type 1 diabetes is an autoimmune disease in which the insulin-producing islet cells in the pancreas are destroyed. Genetic predisposition also plays a role in its development. If the mother has type 1 diabetes, the risk for the child is about 4%. If the father is affected, the risk increases to approximately 8%. If both parents have the disease, the risk is around 30%. Unfortunately, it has not yet been possible to protect children from high-risk families from developing the disease through vaccinations or medications.
When looking at the global distribution of type 1 diabetes, marked regional differences can be observed. In Europe, type 1 diabetes occurs particularly frequently in northern countries. Finland has the highest incidence, with approximately 50 new cases per 100,000 children per year.
Available estimates on the proportion (prevalence) of type 2 diabetes in children and adolescents (<20 years) for Germany, Europe, the United States (Americas), and India.
Please note that type 2 diabetes in children is much less common than type 1, and data are more limited and variable across regions. Where precise prevalence percentages are available, they are reported as cases per 100,000 children or per 1,000, since published data typically use this metric.
Germany (Children and Adolescents)
Prevalence (2022):
• An estimated 18.0 cases per 100,000 children and adolescents aged 11–17 years had type 2 diabetes in Germany in 2022.
This corresponds to roughly 0.018 % of children in this age group. (Diabetes Surveillance)
Additional context:
• National estimates for children <20 years specifically are limited, but registry analyses suggest that type 2 diabetes remains rare relative to type 1 in German youth (estimates in the range of ~0.6 to 2.7 per 100,000 from modeled data). (freidok.uni-freiburg.de)
Europe (Children and Adolescents)
Prevalence patterns:
• Across Europe (outside Germany), type 2 diabetes in children and adolescents remains uncommon but rising. Prevalence estimates differ by country and ethnic group. For example, some European registry data show very low rates (e.g., ~2.9 per 100,000 in England/Wales; ~0.6 per 100,000 in Denmark). (PMC)
General trend:
• Compared with the United States, Europe’s type 2 diabetes prevalence among young people is overall lower, though increasing in parallel with obesity. (PMC)
Note: No uniform Europe-wide percentages are published for children, but available studies emphasize that rates are lower than in North America.
Americas – United States (Children and Adolescents)
Prevalence:
• In the United States, the SEARCH study has documented the youth type 2 diabetes prevalence at approximately 0.67 per 1,000 children/adolescents (equivalent to ~67 per 100,000).
Other analyses show variation by demographic group (higher in some ethnic minorities). (PMC)
This corresponds to roughly 0.067 % of U.S. children and adolescents having diagnosed type 2 diabetes.
India (Children and Adolescents)
Prevalence:
• Nationally representative data are sparse, but region-specific studies indicate higher relative prevalence in some areas compared with Europe and Germany. An international survey reported type 2 diabetes rates in Indian children and teens at approximately 357 per 100,000 (~0.357 %), placing this among the higher documented youth prevalence figures globally. (The Times of India)
Additional observations:
• Other Indian pediatric research highlights elevated pre-diabetes/type 2 diabetes rates among adolescents with obesity, with figures such as 12.3 % in boys and 8.4 % in girls in certain urban study samples (though these include prediabetes). (Springer Nature Link)
Summary – Type 2 Diabetes Prevalence in Children (<20 years)
Region | Approximate Prevalence in Children/Adolescents |
Germany | ~18 per 100,000 (~0.018 %) among 11–17 yrs (Diabetes Surveillance) |
Europe (general) | Low rates (e.g., ~2.9 to ~0.6 per 100,000 in some countries) (PMC) |
United States | ~67 per 100,000 (~0.067 %) (Wiley Online Library) |
India (selected regional data) | ~357 per 100,000 (~0.357 %) (The Times of India) |
Interpretation and Context
Classic symptoms at onset include frequent and excessive urination. In young children, this may present as bedwetting. Children who were previously dry may start wetting again. Additional symptoms include intense thirst, weight loss, fatigue, and reduced performance. If these symptoms occur in children, parents should seek medical attention as soon as possible. In children and adolescents, the effects and symptoms of insulin deficiency are often much more severe than in adults. They are therefore at a higher risk of developing a life-threatening ketoacidotic coma due to severe blood glucose imbalance.
The diagnosis of type 1 diabetes mellitus is initially a shock for both children and their parents. However, they are not alone. Physicians, diabetes educators, psychologists, and other specialists are available to support them in therapy and in everyday life with diabetes. According to current scientific knowledge, people with type 1 diabetes can remain healthy into old age and, with modern medical advances, lead a life with almost no limitations.
