Oro-nasal breathing was not related to snoring, sleep stage, posture, body mass index, height, weight, Rn (2.19 (1.77) cm H2O·L−1·sec−1) or sex, but was positively associated with age. Subjects ≥40 yrs were approximately six times more likely than younger subjects to spend >50% of sleep epochs utilising oro-nasal breathing. Ageing is associated with an increasing occurrence of oro-nasal breathing during sleep. The study was supported by the National Health and Medical Research Council of Australia ER -
