0520 Effect Of Sleep Disordered Breathing On Control And Severity Of Asthma On Pediatric Population

Abstract Introduction Pediatric sleep disordered breathing (SDB) can co-exist with asthma, affecting its control and severity, adding to the overall health care burden. Our aim was determine association of SDB severity evaluate any concomitant risk factors associated both. Methods Based on Sleep-Related Breathing Disorder scale extracted from Sleep Questionnaire (SDBS-PSQ), children (5 – 15 years) persistent asthma were classified as: (SDBS-PSQ ≥ 0.33) without SDB, in a cross sectional study. Characteristics like age, gender, body mass index spirometry compared. Control categorized into well-controlled, not-well, poorly controlled using childhood test (c-ACT ≥20, 12-19 ≤12, respectively). Correlation between SDBS-PSQ c-ACT analysed. adeno-tonsillar hypertrophy, gastroesophageal reflux disease, obesity allergic rhinitis (AR) presence also assessed. Results Among sixty asthmatics, mild, moderate, severe observed 26.67%, 40% 33.33%, respectively. 18.33% asthmatics had for (mean 0.45 ± 0.11 vs 0.07 those p<0.001). Baseline spirometric characteristics similar both groups. Asthmatics higher rates (63.6% 26.5%, p = 0.018) uncontrolled (100% 30.6%, p<0.001), lower mean c–ACT score (14.45 3.20 20.04 4.56, p<0.001) compared SDB. Amongst not-well (0.41 0.12 0.08, <0.001 0.58 0.08 0.01 0.07, p<0.001; respectively), Negative correlation confirmed scores (p<0.001, r2 0.36). Only AR (p 0.001, coefficient <0.001). Conclusion is adversely affected by independent other factors. increase asthmatic children, further control. Therefore, difficult-to-control should be screened objective questionnaires SDBS-PSQ.
