Epidemiological Profile of Polysomnography in Snoring Patients Evaluated in Specialized Medical Service
Introduction: The main types of sleep-disordered breathing, such as snoring and obstructive sleep apnea (OSA) syndrome are highly prevalent in the general population, although it is believed that the most cases continue to go undiagnosed. We should be aware of the main risk factors that favor the onset of these disorders, such as male sex, obesity, and aging.
Objectives: The study aimed to make an epidemiological profile of the patients in a specialized institution according to gender, age, and body mass index (BMI) and its relation to sleep-disordered breathing, evaluated by polysomnography.
Methods: Retrospective study performed through the analysis of 115 results of polysomnography made in a specialized hospital, with patients whose main problem was daily sleepiness.
Results: The polysomnographic examinations of 115 patients, 51 male and 64 female, where analyzed. Among the men, 39.2% had primary snoring, 52.9% OSA syndrome, and 7.8% had alteration on sleep architecture. Among the women, 50% had primary snoring, 32.8% had OSA syndrome, 7.8% had abnormality on sleep architecture, and 9.3% had normal examination. The same patients were divided in four groups by age. Here most of the young had normal polysomnography and the eldest had OSA syndrome. They were also split in five different groups according to BMI. Here the groups with higher BMI presented more abnormalities in the examination.
Conclusion: The results of the polysomnography examinations in the institution are similar to the ones published, if age, gender, and BMI are considered.
