Association between mental work and biological aging: the mediating role of visceral adiposity index
How Mental Work Links to Biological Aging Through Belly Fat Levels
AI simplified
Abstract
Mental workers showed an increase of 1.52 years in biological age acceleration compared to manual workers.
- Biological age acceleration was measured using two methods: and .
- Mental work was linked to greater biological age acceleration, with KDMAge increasing by 1.52 years and PhenoAge by 1.46 years.
- High labor intensity in mental workers correlated with increased biological age acceleration.
- In manual workers, high labor intensity also resulted in increased biological age acceleration, with KDMAge increasing by 1.53 years.
- (VAI) was found to mediate a portion of the relationship between mental work and biological age acceleration.
