Insights
Guardian reports of snoring in children align with objective measurements. This validates using parent snoring surveys for pediatric sleep health research.
Area of Science:
- Pediatric Sleep Medicine
- Respiratory Physiology
- Epidemiology
Background:
- Sleep apnea is a significant concern in pediatric sleep health.
- Epidemiological studies often use guardian-reported snoring as a proxy for sleep apnea.
- The accuracy of guardian-reported snoring data requires validation.
Purpose of the Study:
- To investigate the association between guardian-reported snoring and objective snoring parameters.
- To assess the reliability of subjective snoring reports in children.
Main Methods:
- A cross-sectional study involving 555 Japanese elementary school children.
- Guardian questionnaires collected data on snoring frequency and loudness.
- Objective snoring data were obtained from overnight tracheal sound recordings.
- Statistical analysis included Kruskal-Wallis and Dwass-Steel-Critchlow-Fligner tests.
Main Results:
- Guardian-reported snoring frequency showed a significant positive correlation with objective snoring-time ratio (p < 0.05).
- Snoring loudness reported by guardians correlated with increased equivalent sound pressure levels (Leq, dB) of tracheal sounds.
- Children reporting more frequent or louder snoring had higher objective measurements.
Conclusions:
- Guardian-reported snoring frequency and loudness are significantly associated with objective tracheal sound measurements.
- These findings support the use of guardian reports in epidemiological research on pediatric sleep health.
- Parental reports can be considered a valid tool for assessing snoring in children for sleep studies.
Objectives:
Sleep apnea is a major pediatric sleep health issue. Although many epidemiological studies rely on guardian-reported snoring as a surrogate for sleep apnea, the accuracy of such data remains unclear. This study examines associations between guardian-reported snoring and objective snoring parameters derived from tracheal sound measurements.
Methods:
This cross-sectional study analyzed data from 555 first- and second-grade Japanese elementary school children. Snoring frequency and loudness were reported by their guardians through questionnaires. Objective snoring data were derived from overnight tracheal sound recordings. Differences between subjective and objective measures were assessed using the Kruskal-Wallis test, followed by post hoc pairwise comparisons with the Dwass-Steel-Critchlow-Fligner test.
Results:
Children who "never" snored had the lowest median snoring-time ratio (percentage) of 0.50 (IQR: 0.30-1.10), while the ratio was 0.90 (0.40-2.00) for children who snored "1 night per week," 1.20 (0.40-4.60) for the "2 nights per week" group, and 2.70 (0.70-5.20) for the "≥3 nights per week" group. All snoring groups showed significantly higher ratios than the "never" group (p < 0.05). Similar trends were observed for the equivalent sound pressure level (Leq, dB) of tracheal sounds, which increased stepwise from 88.60 (86.30-90.70) in the "Mildly quiet" group to 89.10 (87.10-92.00) in the "Medium loud" group and 92.60 (88.60-95.20) in the "Loud" group.
Conclusions:
Guardian-reported snoring frequency and loudness were significantly associated with objective measures based on tracheal sound. These findings support the validity of guardian reports in epidemiological studies of pediatric sleep health.
