Aminoacetone is associated with sleep latency.

Area of Science:

• Metabolomics
• Sleep Medicine
• Neuroscience

Background:

• Obstructive sleep apnea (OSA) is associated with daytime sleepiness.
• Metabolites in inflammatory, oxidative stress, and neuronal pathways are implicated in OSA-related sleepiness.
• Sleep latency, a measure of sleep quality, is a key indicator of daytime sleepiness.

Purpose of the Study:

• To investigate the association between specific metabolite concentrations and sleep latency in newly diagnosed, untreated OSA patients.
• To identify potential metabolic mechanisms linking sleep quality and daytime sleepiness in OSA.

Main Methods:

• Cross-sectional study of 88 treatment-naive OSA participants.
• Analysis of fasting morning plasma samples for targeted metabolites.
• Multiple linear regression used to assess associations between metabolites and sleep latency, controlling for covariates (age, sex, BMI, race, smoking, AHI).

Main Results:

• Aminoacetone showed a significant inverse association with sleep latency (p=0.00072).
• Lower aminoacetone levels were observed in participants with longer sleep onset latency (>60 min) compared to those with shorter latency (<15 min).

Conclusions:

• This is the first study to report a relationship between aminoacetone and sleep latency in newly diagnosed OSA.
• Findings suggest aminoacetone may play a role in the mechanisms of sleep latency and sleepiness in OSA.
