According to the apnoea\u2013hypopnoea index (AHI), the subjects were stratified into no OSA, mild\u2013moderate OSA and severe OSA cases.<\/jats:p><jats:p>OSA was present in 62% of the sample, 62% being mild\u2013moderate and 38% severe. No differences were found for BRS value according to sex and OSA severity. 54% of the group had normal BRS value, 36% mild impairment and 10% severe dysfunction. BRS was negatively associated with body mass index (p=0.006), 24-h systolic (p=0.001) and diastolic pressure (p=0.001), and oxygen desaturation index (ODI) (p=0.03). Regression analyses revealed that subjects with lower BRS were those with hypertension (OR 0.41, 95% CI 0.24\u20130.81; p=0.002) and overweight (OR 0.42, 95% CI 0.25\u20130.81; p=0.008), without the effect of AHI and ODI.<\/jats:p><jats:p>In the healthy elderly, the presence of a severe BRS dysfunction affects a small amount of severe cases without effect on snorers and mild OSA.
