Insights
Sleep-disordered breathing (SDB) affects 13.4% of children in Wuxi, China. Atopic diseases and family sleep habits are key risk factors for SDB in this population.
Area of Science:
- Pediatric Sleep Medicine
- Respiratory Health
- Allergy and Immunology
Background:
- Sleep-disordered breathing (SDB) is a prevalent condition in children, impacting immune, cardiovascular, and neurocognitive functions.
- Understanding the prevalence and risk factors for SDB in diverse pediatric populations is crucial for public health initiatives.
Purpose of the Study:
- To determine the prevalence of sleep-disordered breathing (SDB) among children aged 3-14 years in Wuxi, China.
- To identify protective and risk factors associated with SDB in this pediatric cohort.
Main Methods:
- A cross-sectional study involving 3997 children (aged 3-14) in Wuxi, China, utilizing parental questionnaires.
- The Paediatric Sleep Questionnaire (PSQ) assessed SDB risk, with logistic regression analyzing sociodemographic, allergic, and sleep-related factors.
- Data included children's allergy status, sleep patterns, and familial sleep characteristics.
Main Results:
- The prevalence of SDB was 13.4%, with significantly higher rates in children with asthma (28.2%), eczema (19.0%), and rhinitis (21.4%).
- Risk factors for SDB included asthma, eczema, rhinitis, familial sleep sickness, and shorter maternal sleep duration (<8 hours).
- SDB incidence decreased with increasing age, particularly in children aged 6-14 years.
Conclusions:
- Atopic diseases, including asthma, eczema, and rhinitis, are significant risk factors for pediatric SDB in Wuxi.
- Family sleep habits, such as familial sleep sickness and maternal sleep duration, also play a crucial role in children's SDB risk.
- These findings highlight the importance of addressing allergic conditions and family sleep environment in managing pediatric SDB.
Background:
Sleep-disordered breathing (SDB) is a common syndrome in children, related to their immune responses, cardiovascular function, and neurocognitive function. This study aimed to determine the prevalence of SDB among children in Wuxi, China, and to evaluate the protective and risk factors of SDB in children.
Methods:
A cross-sectional study was conducted on children attending different schools across Wuxi, China, aged 3-14 years old. Of a total of 5630 questionnaires distributed to the parents of the children, 3997 (71.0%) were deemed to be valid. The data on the general sociodemographic factors, children's allergy and sleep characteristics, and the parents' sleep characteristics were also collected. The Paediatric Sleep Questionnaire (PSQ) score was used to identify children at high risk of SDB. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression.
Results:
The prevalence of SDB in this cohort was 13.4% (N = 534). SDB prevalence significantly differed in children with asthma (28.2% vs. 12.8%, P < 0.001), eczema (19.0% vs. 10.0%, P < 0.001), urticaria (16.4% vs. 12.9%, P < 0.01) and rhinitis (21.4% vs. 10.7%, P < 0.001). No significant differences were found in SDB prevalence with respect to pillow material or quilt material. On multivariate logistic regression analysis, asthma (OR 1.986 (95% CI 1.312-3.007), P < 0.01), eczema (OR 1.675 (95% CI 1.377-2.037), P < 0.001), rhinitis (OR 1.998 (95% CI 1.635-2.441), suffered from familial sleep sickness (OR 2.416 (95% CI 1.975-2.955), P < 0.001) and whose mothers slept for a shorter duration (6 h-8 h: OR 1.370 (95% CI 1.089-1.724), P < 0.01; <6 h: OR 3.385(95% CI 2.098-5.461), P < 0.001) increased the odds of having SDB. The incidence of SDB significantly decreased with children's age (6-11 years old: 0R 0.768 (95% CI 0.597-0.989), P < 0.05; 12-14 years old: OR 0.691 (95% CI 0.530-0.901), P < 0.01).
Conclusion:
The results of this study demonstrated that atopic diseases (asthma, eczema, and rhinitis) and family sleep habits were risk factors for SDB in children in Wuxi, China.
