PMID 32517546WHAT IT FOUND
Most adults with IBD completed 10 days of wrist activity monitoring and twice-daily sleep diaries, but salivary melatonin timing could not be computed for 29 of 37.
Key findings
0188% of enrolled participants completed the study.
0235 of 37 participants wore the wrist actigraph for at least 9 days, and 34 completed all twice-daily diaries with minimal missing data.
03The salivary melatonin timing measure could not be computed for 29 of 37 participants.

What it does not show
Only 37 adults with IBD were studied, at one academic gastroenterology clinic. It reports feasibility of measurement, not effects of a sleep or circadian intervention. Salivary melatonin timing could not be computed for 29 of 37 participants, so the circadian part of the protocol was not feasible as designed. The researchers could not tell why diaries were missing, such as forgetting or timing out. People with undiagnosed sleep apnea or other sleep disorders may have been included. The sample excluded night or rotating shift workers and people with untreated sleep apnea, so results may not apply to those groups.

The supplied text does not report authors' conflicts of interest. The publication types list NIH extramural and non-U.S. government research support.
The easy way to misread this
Do not read this as evidence that sleep or circadian monitoring changes IBD symptoms or outcomes. It tested whether adults with IBD could complete measurement tasks, and the salivary melatonin timing measure could not be computed for 29 of 37 participants.
