The complex link between sleep-disordered breathing and asthma control in pediatric patients: a cross-sectional study
Abstract
BACKGROUND
In children, asthma and sleep-disordered breathing (SDB) may affect quality of life (QoL), and SDB may complicate asthma management.
OBJECTIVE
To evaluate the prevalence of SDB, its association with asthma control, and risk factors associated with SDB in a cohort of asthmatic children. The effects of asthma control and SDB on QoL were also investigated.
METHODS
We consecutively recruited asthmatic children referred to our Pulmonology Service from 1 December 2022 to 31 May 2023. Data on anthropometrics, respiratory function, and allergies were collected. The prevalence of SDB was assessed by the Pediatric Sleep Questionnaire (PSQ). Asthma control status was assessed by the Childhood Asthma Control Test (C-ACT), while QoL was evaluated by the Pediatric Quality of Life Inventory (PedsQL) questionnaire. Factors associated with SDB were analyzed.
RESULTS
In total 78 asthmatic children aged 5-12 years were included. SDB was found in 37.2% of them, with a higher prevalence in children with uncontrolled versus well-controlled asthma (60.1% vs. 27.3%; p-value =0.005). The C-ACT score was significantly lower in SDB-positive versus SDB-negative group, and uncontrolled asthma (C-ACT ≤19) was associated with a 4.15-fold increased risk of SDB. The PedsQL score was significantly lower in asthmatic children with than without SDB and was associated with lower SDB risk. SDB increased the risk of uncontrolled asthma in children, and asthmatic children with SDB had lower QoL.…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 78 participants or records.
