0091 WHAT CHARACTERIZES THE COMBINATION OF SEEKING MEDICAL HELP FOR INSOMNIA AND SNORING IN TERMS OF PSG AND METABOLIC PARAMETERS?

Abstract

Insomnia and snoring are sometimes occurring in combination, but rather little is known about their interaction with respect to polysomnography (PSG), subjective sleep quality and metabolic parameters. We used a representative set of data of 328 women with one night of in-home PSG. In this set we identified those individuals who had sought medical help for sleep problems (insomnia), and those that had sought help for snoring. Crossing these dimension yielded 4 groups: Good sleepers (Controls, N=250), Insomniacs without snoring (N=40), Snorers with good sleep (N=16) and Snorers with insomnia (N=22). A two-factor analysis of variance was applied to the data (Snore status vs Insomnia status). The results showed significant main effects and interaction for N1%. The highest level was seen for Snorers with insomnia. The same result was seen for AHI/h, and the highest level was seen in Snorers with insomnia (mean AHI=25 vs 8–10 for the others). Again, a similar result was seen for prediabetes (Impaired f-glucose), triglycerides, and the LDL/HDL ratio. N2% and N3% decreased with Insomnia, and awakenings/h increased (no effect of snoring). Reported sleep quality and alertness decreased in insomnia with or without snoring. It was concluded that individuals who had sought help for both insomnia and snoring showed worse PSG sleep, AHI-levels and metabolic profile.
