ABSTRACT

Obstructive sleep apnea and hypopnea syndrome (OSAHS) has been the focus of extensive research because of its association with neurocognitive and cardiovascular complications. The aim of this study was to evaluate the frequency and association between OSAHS and the class of obesity, gender and age in outpatients referred to a sleep laboratory. We selected 1,595 patients, 71.7% male. Mean +/- SD age was 46.7 +/- 11.7 years, BMI was 28.1 +/- 5.1 kg/m2 and AIH was 13.9 +/- 15.5 events/ hour of sleep. The patients were considered apneic when the apnea-hypopnea index (AHI) was > 5 events/hour of sleep; OSAHS was present in: (1) 71.1% of men and 50.3% of women (p < 0.001); (2) in 45.3% of patients with normal BMI, in 64.3% of those overweighed and in 80% of obese (p < 0.001). According to age, 61.2% with age < 55 were apneic, as well as 78% of those with age > 55 years old (p < 0.001). We concluded that OSAHS was directly and strongly associated to the male gender, obesity class and to aging.

ABSTRACT

A síndrome da apnéia e hipopnéia obstrutiva do sono (SAHOS) tem grande importância devido às conseqüências neurocognitivas e cardiovasculares. O objetivo deste estudo foi avaliar a freqüência e associação da SAHOS com a classe de obesidade, gênero e idade, em pacientes ambulatoriais referidos a um laboratório de sono. Foram selecionados 1.595 pacientes (71,7 por cento masculinos) com idade média ± DP de 46,7 ± 11,7 anos e IMC de 28,1 ± 5,1 kg/m². Foi considerado ter apnéia quando o índice de apnéia e hipopnéia (IAH) foi > 5 eventos/hora de sono. A freqüência de SAHOS foi de 71,1 por cento nos homens e de 50,3 por cento nas mulheres (p< 0,001); SAHOS esteve presente em 45,3 por cento dos indivíduos com IMC normal, 64,3 por cento daqueles com sobrepeso, e 80 por cento dos obesos (p< 0,001). Quanto à idade, 61,2 por cento dos pacientes com idade < 55 anos e 78 por cento daqueles com idade > 55 anos tinham SAHOS (p< 0,001). Concluímos que a SAHOS esteve direta e fortemente associada ao gênero masculino, à classe de obesidade e ao envelhecimento.
