Resultados

This sample consisted of 871 patients with mean age = 45 ± (31 – 59) years, male percentage = 52.7%, median BMI = 26.46 (22.4 - 31.2) kg/m², median of the Epworth Scale = 10 (6 - 14.3), mean of bedtime = 22:39 ± 1:32 h, mean of wake-up time = 6:15 ± 1:26 h, mean of total sleep time = 7:31 ± 1:37 h. The most frequent disorders were snoring (86.6%), followed by insomnia (72.1%) and leg movements (52.6%). Women wake up more during the night (76.9% vs 67.8%; p = 0.003), they have more difficulty sleeping (49% vs 34.9%; p < 0.001), they also report more tiredness when waking up (63.8% vs 54%; p = 0.003), besides presenting more daytime sleepiness (62.4% vs 55.6%; p = 0.041) when compared to men. Women reported more body pain (62.4%% vs 39.7%; p < 0.001), they also reported more irritation (49.3% vs 39%; p = 0.002), as well as a weaker memory (58.3% vs 46.8%; p = 0.001), and finally they reported more headache when waking up (34.5% vs 22%; p < 0.001). Men have a higher frequency of daytime sleepiness (24% vs 14.6%; p < 0.001), they snore more (90.2% vs 82.5%, p = 0.001) and bother more third parties when they snore (61.1% vs 54.1%; p = 0.002), they also have a higher frequency of assisted apnea (44.4% vs 30.8%; p < 0.001) when compared to women.
