Resumen

The importance of sociodemographic factors in the evaluation of sleep apnea has been presented recently in a pediatric population. Objective:to evaluate the impact of those factors on cognition of adult patients with OSA.

Methods: A total of 39 patients were recruited. Environmental factors (dwelling and light/dark cycle) and sociodemographic factors were correlated with polysomnography (PSG), brain imaging (MRI) and psychological tests. Results:77% of the patients were highlanders (HL: dwelling above 2000 m asl) and presented a higher frequency of cerebrovascular changes (43%) in contrast with lowlanders (22%). Data as mean±SEM. Differences in Paced Auditory Serial Addition (PASAT) 3 min (HL: 9±1, LL:4±2) were significant (p<0,05). Parameters with statistical significance by sex include working memory (Women:5±0,3; Men:7±0,3; p<0,01) and Frontal Screening Test (Women:20±1,4; Men:24±0,8; p<0,05). Age had negative correlation with Digit Symbol subtest (r=-0,49, p<0,001), Long Term Memory (r=-0,43, p<0,001) and Stroop Color and Word Test (r=-0,31, p<0,05). On the other hand, education had positive correlations with scores for Montreal Cognitive Assessment (r=0,56, p<0,001), working memory (r=0,33, p<0,05), PASAT3 (r=0,36, p<0,05), Long Term Memory storage (r=0,51, p<0,001) and retrieval (r=-0,49, p<0,001). These preliminary findings suggest that Sociodemographic factors play an important role on cognition of OSA patients.
