We aimed to document positional dependency of snoring along with its association with clinical and polysomnographic variables. Seventy\u2010seven apnoeic and 27 non\u2010apnoeic snorers who complained for every\u2010night loud snoring and slept in supine and lateral positions in all sleep stages during overnight polysomnography were included. Snoring (i.e. sound intensity &gt;\u200340\u2003dB) was quantified by measuring the mean and maximum sound intensity, and snoring frequency. In apnoeic and non\u2010apnoeic snorers, mean snoring intensity and snoring frequency were higher in supine than in lateral positions irrespective of sleep stage, and were also usually higher in N3 in comparison to rapid eye movement and\/or N2 sleep stage in any given position. Positional change in snoring intensity as expressed by the ratio of mean intensity in the supine to lateral positions was independently and positively correlated with body mass index, tonsils size and age in the total of patients. Snoring is more prominent in the supine position and in N3 sleep stage in apnoeic and non\u2010apnoeic snorers. Snoring positional dependence is determined by body mass index, tonsils size and age.<\/jats:p>","DOI":"10.1111\/j.1365-2869.2012.01018.x","type":"journal-article","created":{"date-parts":[[2012,5,21]],"date-time":"2012-05-21T05:16:26Z","timestamp":1337577386000},"page":"693-699","source":"Crossref","is-referenced-by-count":21,"title":["Clinical and polysomnographic determinants of snoring"],"prefix":"10.1111","volume":"21","author":[{"given":"IOANNIS","family":"KOUTSOURELAKIS","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ELENI","family":"PERRAKI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"GEORGIOS","family":"ZAKYNTHINOS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ALIKI","family":"MINARITZOGLOU","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"EMMANOUIL","family":"VAGIAKIS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SPYROS","family":"ZAKYNTHINOS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,5,21]]},"reference":[{"key":"e_1_2_6_2_1","volume-title":"The International Classification of Sleep Disorders: diagnostic and coding manual","author":"American Academy of Sleep Medicine","year":"2005"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/22.5.667"},{"key":"e_1_2_6_4_1","first-page":"341","article-title":"Praat, a system for doing phonetics by computer","volume":"5","author":"Boersma P.","year":"2001","journal-title":"Glot.
