Personal-MetaboHealth, an actionable health check in middle age, is improved by an effective lifestyle intervention in those at risk https://www.medrxiv.org/content/10.64898/2026.02.15.26346369v1

Personal-MetaboHealth thus offers a potential actionable health check in middle age for early prevention and extension of healthy lifespan.

In addition, we show that Personal-MetaboHealth can be improved by a 3-month combined lifestyle intervention in middle aged individuals (Growing Old Together study), specifically in those at risk with an unhealthy score at baseline.

Using data from the Leiden Longevity Study, we show that Personal-MetaboHealth retained predictive accuracy for all-cause mortality and showed an even stronger association with incident cardiometabolic disease in comparison to the original MetaboHealth score.

What started as a student project from Gabriela Natalle Lopes together with Niels vd Berg has now become a fleshed out preprint in which we present Personal-MetaboHealth, a personalised version of MetaboHealth based on clinically validated metabolic biomarkers.

Met een kleine correctie; we leven op dit moment in Nederland gemiddeld 82 en geen 90 jaar.

This includes a variant in cGAS, for which we subsequently showed it leads to a reduced function of the protein in cell lines from both humans and mice, which nicely complements earlier work on this protein in animal models.

Key takeaway: Absence of CAD disease risk alleles is one key-feature linked to longevity and alleles linked to cholesterol metabolism are a key component in healthy aging trajectories.

I'm very happy to see this paper now out. We used early-life climbing ability to separate genetically identical short-lived and long-lived sub-cohorts of fruit flies, and to identify metabolites and metabolite modules that predict longevity.
