Background: With the recent increased awareness of youth-onset type 2 diabetes (T2D) cases, an overview of national differences in epidemiology data is needed to obtain a global picture of the disease development.
Methods and Aim: This review examined national epidemiology data of youth-onset T2D published between 1st January 2008 and 15th January 2018, and searched for national guidelines on this topic to understand better national similarities and differences.
Results: Of the 1005 articles and 14 congress abstracts identified, 42 studies were included. The highest reported prevalence rates of youth-onset T2D were found in the U.S. and China (38 and 18 cases/100,000 people, respectively), and lowest in Denmark and Ireland (0.6 and 1.2 cases/100,000 people, respectively) (Figure). However, the highest incidence rates were reported in Taiwan and the UK (63 and 33 cases/100,000 people, respectively), with the lowest in Fiji and Austria (0.4 and 0.6 cases/100,000 people, respectively) (Figure). These differences may be partly explained by variations in diagnostic criteria, national screening recommendations, and ethnicity within countries.
Conclusions: Our review suggests that published national epidemiology data for youth-onset T2D may underestimate its disease burden. Finding optimal diagnostic criteria and screening strategies for this disease should be of high interest to every country.
