Insights

The Pediatric Sleep Questionnaire (PSQ) shows high sensitivity for screening obstructive sleep apnea (OSA) in children with asthma, but low specificity. It can serve as an initial screening tool for pediatric asthma patients at risk for OSA.

Area of Science:

  • Pediatric Pulmonology
  • Sleep Medicine
  • Respiratory Health

Background:

  • Obstructive sleep apnea (OSA) is more prevalent in children with poorly controlled asthma.
  • Effective screening tools are crucial for early detection and management of OSA in this vulnerable population.
  • The Pediatric Sleep Questionnaire (PSQ) is a potential tool for OSA screening in asthmatic children.

Purpose of the Study:

  • To evaluate the diagnostic validity of the Pediatric Sleep Questionnaire (PSQ) for screening obstructive sleep apnea (OSA) in children diagnosed with asthma.
  • To determine the correlation between PSQ scores, obstructive apnea-hypopnea index (OI), and spirometry results in pediatric asthma patients.

Main Methods:

  • Retrospective review of sleep studies and medical records for 160 asthmatic children over 13 years.
  • Calculation of validity measures using various cut-off values for the obstructive apnea-hypopnea index (OI) and PSQ scores.
  • Assessment of correlations between PSQ, OI, and spirometry using Spearman's correlation coefficient.

Main Results:

  • A statistically significant correlation was found between OI and PSQ scores (r=0.19, P=0.015).
  • Using a PSQ cutoff of 0.33, sensitivities ranged from 76.2% to 81.6%, with specificities between 13.1% and 14.4%.
  • Raising the PSQ cutoff to 0.5 improved specificity to 36.9% but decreased sensitivity to 71.1%.

Conclusions:

  • The PSQ demonstrates high sensitivity for detecting OSA in children with asthma, comparable to previous research.
  • However, the specificity of the PSQ for this population remains low.
  • The PSQ can be considered a suitable preliminary screening instrument for OSA in asthmatic children.
