SUMMARY

Background. Childhood asthma, a chronic inflammatory disease, is linked to sleep-breathing disorders (SBD). The vulnerability of asthmatic children to SBDs is well-established, yet limited research focuses on adolescents. This study addresses the research gap, exploring the frequency and risk factors of SBD in adolescents with asthma. Methods. A cross-sectional study was conducted among 98 adolescents (12-17 years) with asthma at a Lisbon healthcare facility. Comprehensive assessments, including sociodemographic data, medical history, lung function variables, and validated questionnaires for SBD risk (Pediatric Sleep Questionnaire), rhinitis control, and asthma control (Control of Allergic Rhinitis and Asthma Test and Asthma Control Test), were employed. Results. The study revealed a substantial frequency of SBD symptoms, with 25.5% of adolescents classified as high-risk based on the Pediatric Sleep Questionnaire. Significant associations were identified between high SBD risk and elevated body mass index (BMI), uncontrolled rhinitis, and uncontrolled asthma. Logistic regression analysis confirmed elevated BMI as a robust predictor of SBD risk, indicating a 5.9-fold increase compared to normal-weight counterparts. Conclusions. This study contributes valuable insights into the interplay between asthma and SBD in adolescents. The high prevalence of SBD symptoms, particularly among those with excess weight and uncontrolled respiratory symptoms, underscores the need for targeted preventive strategies. The identified risk factors, notably elevated BMI, provide clinicians with actionable information for intervention, emphasizing the importance of addressing modifiable factors associated with asthma and SBD in this specific population.
