Abstract
A sex-specific metabolic aging clock was developed using data from 390,941 individuals in the UK Biobank.
- Dysregulation of cholesterol metabolism, immune response, blood clotting, and cell growth is linked to accelerated metabolic aging in both sexes.
- Oxidative stress detoxification, cellular resilience, and tissue integrity are associated with decelerated metabolic aging in both males and females.
- In females, additional dysregulation of carbohydrate metabolism, circadian rhythms, and hormone metabolism is observed that accelerates aging.
- Energy metabolism and cancer-related pathways are specifically disrupted in males, accelerating their metabolic aging.
- Reproductive factors such as late puberty and higher parity may help decelerate metabolic aging in both sexes.
- Accelerated metabolic age predicts higher morbidity and mortality rates, particularly in males, with obesity explaining most disease associations in females.
