A recent Colorado study reveals an alarming rise in type 2 diabetes among teenagers, with cases increasing nearly tenfold since 2002, prompting new concerns over diagnosis and prevention strategies in young people.
A long-running Colorado study suggests type 2 diabetes in teenagers is rising far faster than type 1 diabetes, adding urgency to concerns that a condition once seen mainly in adults is becoming a growing paediatric problem. Research to be presented at the European Association for the Study of Diabetes meeting in Milan found that new cases of type 2 diabetes among 10- to 19-year-olds in the state climbed almost tenfold between 2002 and 2023, while type 1 diabetes rose only modestly.
The Colorado Diabetes Registry tracked diabetes incidence across the state for more than two decades, using diagnosis codes, laboratory results and medication data from health systems. In that period, researchers recorded 1,560 new type 2 diabetes cases in young people aged 10 to 19 and 8,094 new type 1 cases in those under 20. According to the study, type 2 incidence rose from 2.37 cases per 100,000 in 2002 to 22.30 in 2023, with the sharpest acceleration in the later years. Type 1 diabetes also edged higher, but at a much slower pace.
The findings fit a broader national pattern. The US Centres for Disease Control and Prevention has reported that new diabetes diagnoses among young people have been increasing for years, with type 2 cases in those under 20 doubling between 2002 and 2018. Analyses from the SEARCH for Diabetes in Youth study, published in The Lancet Diabetes & Endocrinology and discussed in Diabetes Care, similarly found a steady rise in youth-onset type 2 diabetes, underscoring that Colorado is not an outlier.
Dr Tessa Crume of the Colorado School of Public Health said the shift has changed the everyday reality of paediatric care. She noted that clinicians are now far less surprised to encounter type 2 diabetes in adolescents than they were a generation ago, but warned that many cases can still be missed in primary care because of the old assumption that diabetes in children is usually type 1. The problem, she said, is not only access to treatment but correct diagnosis from the start.
That distinction matters because the two conditions require different testing and can look similar at first. Doctors increasingly need both autoantibody testing, which can point to type 1 diabetes, and measures of insulin resistance, which are more consistent with type 2. The study authors say this is especially important as rising obesity rates blur the clinical picture in teenagers with high blood sugar and higher body mass.
Crume also warned that youth-onset type 2 diabetes can be more aggressive than the same diagnosis in middle age, with complications affecting the kidneys, eyes, nerves and heart emerging much sooner. She said prevention has to begin in families and communities, with support for healthy meals, water instead of sugary drinks, physical activity and better access to nutritious food. Families, she added, cannot solve the problem alone if healthier choices remain the hardest ones to make.
