The Claim

Elevated copeptin levels are associated with incident diabetes in older men, and this association is partially mediated by insulin resistance, as indicated by a reduction in hazard ratio from 1.78 to 1.47 after adjustment for HOMA-IR, with insulin sensitivity accounting for approximately 17% of the observed risk.

How it works
1 study reviewed
In plain English

In older men, higher levels of copeptin are linked to a higher risk of developing diabetes, and about 17% of this link is explained by insulin resistance as measured by HOMA-IR.

See the scientific wording

The association between elevated copeptin and incident diabetes in older men is partially mediated by insulin resistance, as the hazard ratio decreases from 1.78 to 1.47 after adjusting for HOMA-IR, indicating that insulin sensitivity explains about 17% of the observed risk.

Why this might work

High levels of copeptin signal increased activity of a stress hormone that triggers inflammation, disrupts blood vessel function, and forces the pancreas to overwork producing insulin. This causes the body’s tissues to stop responding properly to insulin, leading to high blood sugar. Over time, the pancreas wears out and can no longer keep up, resulting in diabetes.

  1. Study: Copeptin, Insulin Resistance, and Risk of Incident Diabetes in Older Men

    Higher levels of a substance called copeptin are linked to a higher chance of getting diabetes in older men, and part of that link is because copeptin is tied to the body being less sensitive to insulin. But even after accounting for that, copeptin still raises diabetes risk, meaning something else is going on too.
