Understanding how lipids affect blood vessels and insulin in night-shift workers

Official title: Impact of circulating and tissue-specific lipids on vascular function and insulin sensitivity in chronic night shift workers

Funded at Colorado State University · NIH-11261650 · Data updated 2026-11-12

A study will look at how specific fats circulating in the blood and in tissues relate to blood vessel function and insulin sensitivity in adults who work night shifts.

Who could benefit from this research

Could help

Adults with night-shift work schedules or circadian disruption who are at risk for cardiometabolic disease.

Less likely to help

People without circadian disruption or those not at risk for metabolic or vascular issues may see limited direct benefit.

What this research studies

If you work night shifts, your body’s internal clock can get confused, which may affect fats in your blood and muscle that influence heart health and diabetes risk. This project tests how circulating lipids and lipids in muscle relate to how well blood vessels dilate and how your body uses insulin during circadian disruption. Researchers will study adults around 21 and older, collecting blood, tissue samples, and functional measures to connect lipid changes with vascular and metabolic responses. The work may help identify lipid targets to protect heart and metabolic health in people who routinely work at night.

Why it matters

Potential benefit: If successful, findings could lead to new strategies to protect cardiovascular and metabolic health for night-shift workers.

How similar studies have gone: Prior research shows lipids and circadian disruption affect vascular and insulin pathways, with emerging evidence in shift workers.
