Summary
This summary is machine-generated.Seasonal factors impact childhood obstructive sleep apnea-hypopnea syndrome (OSAHS) severity. Severe OSAHS and respiratory events are more frequent in winter and spring, particularly in young children.
Area Of Science
- Pediatric Respiratory Medicine
- Sleep Science
- Environmental Health
Background
- Limited data exist on seasonal influences on childhood obstructive sleep apnea-hypopnea syndrome (OSAHS) in China.
- Investigating seasonal effects on OSAHS severity is crucial for understanding pediatric sleep disorders.
Purpose Of The Study
- To examine the correlation between seasonal variations and the severity of obstructive sleep apnea-hypopnea syndrome (OSAHS) in children.
- To identify specific seasonal patterns in OSAHS prevalence and associated respiratory events.
Main Methods
- Children aged 2-16 with suspected OSAHS underwent full-night polysomnography (PSG).
- Data from December 2016 to February 2022 were analyzed for seasonal correlations with PSG findings.
- Prevalence of conditions like tonsillar hypertrophy, adenoid hypertrophy, rhinitis/sinusitis, and asthma were assessed seasonally.
Main Results
- Severe OSAHS was diagnosed more frequently in winter (30.2%) compared to summer (24.6%).
- Increased respiratory events, including higher respiratory arousal and REM-apnea indices, were observed in winter and spring.
- Higher proportions of rhinitis/sinusitis and tonsillar hypertrophy occurred in spring, while adenoid hypertrophy was more prevalent in winter.
Conclusions
- Seasonal factors, particularly winter, are associated with increased severity and respiratory events in pediatric OSAHS.
- Younger children (≤6 years) showed heightened susceptibility to seasonal variations in respiratory events.
- Findings suggest a notable impact of seasons on the manifestation and severity of childhood OSAHS.

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...
Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.
Chest Configuration
The chest configuration...
Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
Health history and...
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
