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.
GoodSupportsHIGH confidence
Smoking and increased body mass indices were associated with elevated levels of biomarkers of DNA damage independent of the age of the individuals.
Why this rating
Observational cohort study with statistical correction for age. The association is significant (P=0.0063) for the biomarker combination score.
