Brief Summary: The incidence of Type 1 diabetes (T1D) in children and adolescents is increasing in many nations. The 10th edition of the International Diabetes Federation Atlas reports that an estimated 108,300 youth aged < 15 years and 149,500 < 20 years were diagnosed with T1D in 2021.

The 10th edition of the International Diabetes Federation Atlas estimates that globally 1,211,900 children and adolescents younger than 20 years have T1D. Comparisons to previous data confirm the steady increase in T1D incidence over the last 20 years. Overall, the numbers show marked differences in the age-standardized incidence between countries. Based on excellent quality data from countries such as Finland (high incidence) and Japan (low incidence), large differences in age-standardized T1D incidence are known to be real. However, in many parts of the world, limitations are present, and many extrapolations were required, all well described in the article.

Looking at the world map that shows the countries with data and how recent the data are, one can easily see that data are unavailable for most countries in sub–Saharan Africa and in Southeast Asia. Data for children aged 0–14 years are based on reports from < 50% of countries and for youth aged 15–19 years from < 15% of countries. Obtaining high quality data from as many countries as possible should be a key priority in order to understand the epidemiology of T1D diabetes and better advocate for improved management of T1D in youth. There is an opportunity for pediatric endocrinologists working in countries where the characteristics of T1D are poorly documented to advocate for better data.
