How Mental Work Links to Biological Aging Through Belly Fat Levels
Updated
Abstract
Essence
Mental work and higher work intensity were linked to faster biological aging, partly through visceral adiposity.
Evidence
A cross-sectional analysis of 3,933 Kailuan cohort participants found mental work associated with 1.46 higher and 1.52 higher acceleration versus manual work, with mediating 9.8% and 20.9% of those relationships.
Caveat
The observational cross-sectional design cannot show that mental work, work intensity, or VAI caused faster biological aging.
