FREQUENCY OF SLEEP DISORDERS IN PATIENTS WITH INSOMNIA
Insomnia is a global healthcare problem and is defined by a subjective feeling of inability to start sleeping or the sensation of disturbed sleep or to maintain sleep. It affects both physical and mental spheres, thus reducing the life quality and sometimes even the lifespan.
To identify the insomnia frequency in patients at a sleep clinic.
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 complaining of insomnia who answered questionnaires with information about the characteristics of sleep 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 362 patients, mean age = 47 (32-60) years, female frequency = 55.8%, median BMI = 25.9 (22.3-31.7) kg/m², median Epworth Scale = 9 (5-13), mean of bedtime = 22:51±1:40 h, mean of wake-up time = 6:14±1:38 h, mean of total sleep time = 7:13±1:44 h. The most frequent sleep disorders in individuals who reported difficulty in initiating or maintaining sleep were: snoring (83.4%), tiredness when waking up (66.6%) and memory impairment (59.7%). Women presented a higher frequency of headaches on waking up when compared to men (40.1% vs. 25.6%; p=0.004), as well as in relation to body pain (69.8% vs. 43.8%; p<0.001), respectively. On the other hand, men presented a higher frequency of assisted sleep apnea in relation to women (42.5% vs. 28.7%; p=0.006); men also presented a higher frequency of snoring when compared to women (88.1% vs. 79.7%; p=0.032).
In the present study it was possible to observe that insomnia was more frequent in women and it was associated with snoring, tiredness when waking up and memory impairment. Women with insomnia have a higher frequency of headache on waking up and body pain when compared to men, while men have a higher frequency of assisted apnea and snoring when compared to women.
