Genetic and Environmental Influences on Longitudinal Trajectories of Functional Biological Age: Comparisons Across Gender

We used an alternate age variable, functional biological age (fBioAge), which was based on performance on functional body measures. The aim was to examine development of fBioAge across the adult life span, and to also examine potential gender differences and genetic and environmental influences on change with age. We used longitudinal data (n = 740; chronological age (ChronAge) range 45–85 at baseline) from the Swedish Adoption/Twin Study of...
