Higher Body Mass Index (BMI) is directly associated with increased serum levels of biomarkers for DNA damage and telomere dysfunction, independent of chronological age.

Higher body weight (BMI) is associated with higher levels of DNA damage and telomere dysfunction markers in your blood, regardless of your age. Maintaining a healthy weight may help reduce these biological markers of aging.
