Childhood obesity linked to accelerated biological aging

Data from the Robert Koch Institute indicates that approximately 15 percent of children and adolescents aged 3 to 17 in Germany are overweight, with about 6 percent suffering from obesity. While historical data showed a stabilization of these figures, recent observations following the COVID-19 pandemic suggest concerning trends regarding nutrition, movement, and weight.

A long-term Finnish study published in the ‘International Journal of Obesity’ has linked high Body Mass Index (BMI) during adolescence to accelerated biological aging in adulthood. By using epigenetic clocks to measure chemical changes in DNA, researchers from the University of Jyväskylä found that individuals with higher BMIs in their youth showed signs of faster aging. This effect appears even more pronounced in individuals with a genetic predisposition to higher body weight, potentially increasing the long-term risk of chronic diseases and early mortality.
