Circadian rhythms and abdominal pain in teens

Official title: The Relationship of Circadian Phase and Functional Abdominal Pain in Adolescents

Funded at Cincinnati Childrens Hosp Med Ctr · NIH-11353719 · Data updated 2026-11-12

Teens with functional abdominal pain may have a body clock timing issue, and this study looks at how circadian phase relates to their pain and daily functioning.

Who could benefit from this research

Could help

Adolescents with functional abdominal pain disorders and age-matched controls.

Less likely to help

Healthy adolescents without abdominal pain or those unable to participate in sleep assessments.

What this research studies

This research explores whether the timing of the body clock (circadian phase) is delayed in adolescents with functional abdominal pain disorders and how that timing relates to their pain, nausea, and ability to function at school and home. The team will measure circadian phase using dim light melatonin onset (DLMO) and compare results with a control group of adolescents. They will examine how objective circadian phase correlates with patient-reported abdominal pain and related symptoms. The study builds on preliminary data suggesting melatonin treatment may help pain, aiming to clarify mechanisms and potential targets for therapy.

Why it matters

Potential benefit: If successful, could lead to new timing-based approaches to reduce pain and improve daily functioning for adolescents with FAPD.

How similar studies have gone: Prior work indicates a link between sleep and pediatric abdominal pain, with mixed findings on objective sleep measures and pain correlation.
