Trial Outcomes & Findings for Metabolomics of Insomnia-Related Hyperarousal (NCT NCT01957111)

NCT ID: NCT01957111

Last Updated: 2017-01-11

Results Overview

Metabolomics analysis of blood samples were carried out using Spectroscopy. This approach allows for rapid, unbiased and quantitative metabolic profiles ('fingerprints) to be acquired. A total of 70 metabolites were measured and compared between individuals with insomnia and good sleepers.

Participant Flow

Participants were recruited from the general community and consisted of a group of with chronic insomnia disorder and age- and sex-matched good sleepers.

Measure
Individuals With Insomnia
Participants with insomnia met the following Research Diagnostic Criteria for primary insomnia: subjective complaint of difficulty initiating or maintaining sleep, waking up too early or nonrestorative sleep, daytime consequences as a result of the poor sleep, duration of at least 1 month, sleep disturbance is not secondary to a medical or psychiatric condition based or the effects of a substance, as determined by clinical history. In order to exclude individuals with mild insomnia, insomnia had to occur on 3 or more nights per week for three months or longer. A 30-minute criterion was used such that subjects had to report taking 30 minutes or longer to fall asleep and/or spend 30 minutes awake during the night.
Good Sleepers
To be considered a good sleeper, participants had to report that they did not have difficulty falling asleep or staying asleep. A 15-minute criterion was used such that subjects had to report taking 15 minutes or less to fall asleep and spend 15 minutes or less awake during the night.

SECONDARY outcome

Timeframe: 1 night

Participants will have their sleep measured with polysomnography for one night. The sleep of individuals with insomnia will be compared to that of good sleepers. Sleep quality is defined as sleep efficiency, which is calculated at total sleep time / total time spent in bed x 100. It indicates the % of time spent asleep while in bed.
