Vitamin A May Help Explain the Link Between Metabolic Syndrome and Hearing Loss

Based on: Association between metabolic syndrome and hearing loss: The mediating role of retinol - A cross-sectional analysis of NHANES 2007 to 2018 (excluding 2013-2014).

Preliminary Evidence·Journal Article·Medicine·Jun 2026

Adults with metabolic syndrome (high blood pressure, blood sugar, and belly fat together) tended to have slightly worse hearing. In this look at nearly 9,000 American adults, retinol (vitamin A) seemed to play a protective role in the inner ear. The hearing difference was small, and this only shows a link, not cause and effect.

Key Insight

This study suggests vitamin A may matter for inner ear health in people with metabolic syndrome.

Worse Metabolic Syndrome Tied to Faster Cognitive Decline in Older Adults

Among Chinese adults over 60, having more severe metabolic syndrome was linked to faster mental decline over several years. The connection held for both overall cognition and memory specifically. People in the worst quarter of cumulative metabolic syndrome scores declined in memory about three times faster than those in the best quarter. These findings come from two large studies tracking participants for up to eight years.
