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.

  1. 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”

1 study
  1. 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).”
