Obstructive Sleep Apnea and Hypopnea Syndrome (OSAHS) is characterized as a disorder caused by repetitive and intermittent closure of the upper airways during sleep, due to total collapse of the pharyngeal walls and it is associated with several symptoms and comorbidities. It is believed that about 33% of men of productive age are affected by the syndrome.


To evaluate the factors associated with sleep-disordered breathing.


This is a cross-sectional study. Study sample: Individuals who sought a sleep laboratory in Salvador (BA) were evaluated. Project approved by the research ethics committee. Inclusion criteria: Patients with complaints related to sleep-disordered breathing who answered questionnaires with information about sleep characteristics which were applied between 2014 and October/2018 in individuals of any age, gender, who sought a sleep laboratory in Salvador (BA). Exclusion criteria: Medical records with incomplete data.


This sample consisted of 754 patients complaining of snoring, with a mean age of 46 (31.8-59) years, median BMI: 27 (23-31.6) kg/m2, mean of bedtime: 22:39 ± 1:33 hours, mean of wake-up time: 6:14 ± 1:27 hours, mean of total sleep time: 7:30 ± 1:38 hours. The main characteristics of these individuals were: sleep fragmentation (71.4%), snoring that bothers (67.5%), excessive daytime sleepiness (58.4%), and fatigue when waking up (57.3%). Women had greater difficulty in initiating and maintaining sleep when compared to men (47.5% vs. 34.1%; p<0.001). Men presented higher frequency of assisted apnea (47.1% vs. 35.6%; p = 0.001) and excessive daytime sleepiness (24.2% vs. 13.8%; p < 0.001).


The present study showed that individuals with sleep- disorder breathing had sleep fragmentation, excessive daytime sleepiness and fatigue on waking. Women had greater difficulty in initiating and maintaining sleep when compared to men, while men had greater frequency of assisted apnea and excessive daytime sleepiness.
