Insights

Wheezing in school-aged children is linked to poor sleep quality, including nocturnal awakenings and restless sleep. These children also experience more daytime sleepiness and tiredness, impacting their overall well-being.

Area of Science:

  • Pediatric Respiratory Health
  • Sleep Medicine
  • Allergy and Immunology

Background:

  • Wheezing is a common respiratory symptom in children.
  • Sleep disturbances can negatively impact a child's health and development.
  • The relationship between wheezing and sleep quality in school-aged children requires further investigation.

Purpose of the Study:

  • To examine the association between wheezing and disturbed sleep in school-aged children.
  • To assess the link between wheezing and increased daytime symptoms.
  • To identify risk factors for sleep disturbances in children with respiratory symptoms.

Main Methods:

  • A random sample of 1234 children aged 6-14 years from Antwerp participated.
  • Data collected using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire and a sleep questionnaire.
  • Statistical analysis, including odds ratios, adjusted for potential confounders.

Main Results:

  • Children who wheezed reported more disturbed sleep (nocturnal awakenings, restless sleep) and daytime sleepiness/tiredness.
  • Wheezing was positively associated with difficulties falling asleep (OR=2.0), restless sleep (OR=5.0), daytime sleepiness (OR=3.8), and daytime tiredness (OR=5.1).
  • Chronic cough, rhinitis, snoring, and eczema were associated with disturbed sleep and/or daytime tiredness.

Conclusions:

  • Wheezing in school-aged children is significantly associated with decreased sleep quality and increased daytime fatigue.
  • Upper airway symptoms, such as chronic cough and rhinitis, are linked to sleep disturbances in this population.
  • These findings highlight the importance of addressing respiratory symptoms to improve sleep and daytime functioning in children.

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
