Insights

Sleep-disordered breathing (SDB) affects 17.7% of Shanghai children, linked to allergic rhinitis, enlarged tonsils, and parental snoring. Mandible retrusion was also associated with higher SDB prevalence.

Area of Science:

  • Pediatric Sleep Medicine
  • Orthodontics
  • Public Health

Background:

  • Sleep-disordered breathing (SDB) is a growing concern in pediatric populations.
  • Understanding the prevalence and risk factors of SDB in urban Chinese children is crucial for early intervention.

Purpose of the Study:

  • To determine the prevalence and independent risk factors of SDB in 6-11-year-old children in Shanghai.
  • To explore the association between SDB and malocclusion in this population.

Main Methods:

  • Cross-sectional study utilizing cluster sampling with 3433 participants.
  • Pediatric Sleep Questionnaire (PSQ) for SDB assessment; medical, family history, and habit questionnaires.
  • Oral examinations by orthodontists; multivariable logistic regression and Chi-square tests for analysis.

Main Results:

  • SDB prevalence was 17.7%.
  • Independent risk factors included allergic rhinitis, adenotonsillar hypertrophy, and parental snoring.
  • Higher SDB prevalence was observed in children with retrusive mandibles, but no significant correlation with other malocclusion types.

Conclusions:

  • High SDB prevalence in urban Chinese children, associated with mandible retrusion.
  • Key risk factors identified: allergic rhinitis, adenotonsillar hypertrophy, and parental snoring.
  • Emphasizes the need for public education on SDB and dental-maxillofacial abnormalities.

Sleep Apnea01:21

Sleep Apnea

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...

Other Pulmonary Disorders01:17

Other Pulmonary Disorders

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.

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Physical Assessment of the Respiratory Tract II: Inspection

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...
