Insulin resistance causes high blood pressure in adults through effects on the kidneys and blood vessels.

Is it true that insulin resistance causes high blood pressure in adults through effects on the kidneys and blood vessels?

Partly. Several sources partially support the claim: a review and a Japanese clinical paper describe renal sodium retention and endothelial dysfunction as mechanisms linking insulin resistance to high blood pressure, and a dog study found a direct relationship between insulin resistance and rising blood pressure. However, a rat study argues that compensatory hyperinsulinemia rather than insulin resistance itself raises blood pressure, so the causal picture is only partly covered and contested.
