Multimorbidity
Disease3 papers5 findings
Human cohort studies link multimorbidity risk to childhood food deprivation, partly mediated by biological age, as well as to biological age uncertainty and female epigenetic puberty timing.

mediatesin humans1
Light-BioAge mediates multimorbidity in humans (4.9% and 5.3% proportion mediated).
“Exploratory causal mediation analysis indicated that Light-BioAge accounted for a small proportion (4.9% and 5.3%) of the total effects, with indirect effects close to the null”

Childhood food deprivation raises the risk of multimorbidity in humans (HR 1.43, 95% CI: 1.25-1.63).
“Further adjustment for lifestyle and health-related covariates yielded HRs of 1.17 (95% CI: 1.07-1.28) and 1.43 (95% CI: 1.25-1.63).”

Biological age uncertainty independently predicts mortality and health decline in humans
Researchers derived biological age uncertainty across UK Biobank participants, finding that higher uncertainty reflects reduced physiological coherence and predicts worse health outcomes.
