Clinical trial for PreDiabetes
Official title Night Owl Metabolism
ClinicalTrials.gov ID: NCT06507722
What this study is testing
- What it's testing
- The study will compare blood sugar and insulin response when a glucose test or first meal is scheduled at a person’s normal sleep‑wake time versus a time that does not match their chronotype. It also looks at how blood sugar rises after meals and whether late sleepers have delayed melatonin that might affect glucose control.
- Who it's for
- Youth aged 18 to 23 who are overweight, have prediabetes, or have impaired glucose tolerance and who have a late or non‑late sleep pattern.
- What's involved
- Participants will take two oral glucose tolerance tests, one at their usual sleep time and one at a different time, and will eat two standard meals, each at a different time, while wearing a continuous glucose monitor. Some will also have a small study of melatonin under dim light.
- Time commitment
- The study lasts about a week, with two testing days and two meal days, plus a brief melatonin assessment for a subset of participants.
