Biological aging mediates the associations of metabolic score for insulin resistance with all‐cause and cardiovascular disease mortality among US adults: A nationwide cohort study

This study highlights the detrimental effects of insulin resistance, as measured by METS-IR, on all-cause and CVD mortality. Moreover, it underscores the role of biological ageing in mediating these associations, emphasizing the need for interventions targeting both insulin resistance and ageing processes to mitigate mortality risks in metabolic disorders.
