Prediabetes is on the rise among Finnish kids with overweight or obesity, jumping from 11% in the early 2000s to 50% in 2017-2019. This increase is linked to a rise in maternal overweight, which went from 20% to 69% over the same period. Researchers are concerned as prediabetes increases the risk of type 2 diabetes and other health issues, and say early screening and intervention are crucial for kids with obesity-related issues.
