Insights

Low birthweight, obesity, and pet exposure before birth are linked to uncontrolled pediatric asthma. Severe rhinitis significantly increases the risk of poor asthma control in children.

Area of Science:

  • Pediatric Pulmonology
  • Environmental Health
  • Allergy and Immunology

Background:

  • Asthma control is the primary goal of treatment, yet its determinants remain incompletely understood.
  • Identifying factors influencing pediatric asthma control is crucial for effective management strategies.

Purpose of the Study:

  • To assess factors associated with asthma control in a general population of pediatric patients.
  • To identify environmental, demographic, and comorbid disease associations with uncontrolled asthma.

Main Methods:

  • A Web-based survey was conducted in June 2012 targeting Japanese children aged 6-11 years with current asthma.
  • Asthma control was evaluated using the Childhood Asthma Control Test (C-ACT), with uncontrolled asthma defined as a C-ACT score <20.
  • Associations between uncontrolled asthma and various factors were analyzed using multivariable analysis.

Main Results:

  • Out of 3066 children with asthma, 14.6% had uncontrolled disease.
  • Low birthweight (aOR 1.65), obesity (aOR 1.44), and pre-birth pet ownership (aOR 1.68) were associated with uncontrolled asthma.
  • Comorbid allergic rhinitis, particularly severe rhinitis (aOR 3.88), was a significant risk factor, inversely correlated with C-ACT scores (p < 0.001).

Conclusions:

  • A population-based survey identified several factors associated with poor pediatric asthma control.
  • Factors like low birthweight, obesity, pre-birth pet exposure, and severe rhinitis are key indicators for identifying children at risk of uncontrolled asthma.

Asthma-I: Introduction01:29

Asthma-I: Introduction

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...

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...

Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Asthma III: Clinical Manifestations01:13

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,...
