Insights

Caesarean section delivery was not linked to childhood asthma in Malaysian children. A family history of atopy and early introduction of solid foods were significant factors influencing asthma development.

Area of Science:

  • Pediatric Allergy and Immunology
  • Epidemiology
  • Obstetrics and Gynecology

Background:

  • Previous studies suggest a correlation between caesarean section birth and increased asthma risk.
  • Understanding this association is crucial for public health initiatives and early intervention strategies.

Purpose of the Study:

  • To investigate the association between caesarean section delivery and the development of asthma in Malaysian children.
  • To identify other potential risk and protective factors for childhood asthma in this population.

Main Methods:

  • A case-control study was conducted with 156 Malaysian children (aged 3-15 years).
  • Seventy-eight children diagnosed with asthma (cases) were matched with 78 children without asthma (controls).
  • Data on delivery mode, family history of allergies, total serum IgE levels, and skin prick test results were collected.

Main Results:

  • No significant association was found between caesarean section delivery and childhood asthma (OR = 1.21, p = 0.596).
  • Children born via caesarean section did not exhibit higher IgE levels or increased aeroallergen sensitization.
  • A positive family history of atopy strongly predicted asthma (OR = 13.8, p < 0.001), while introducing semi-solid foods after 6 months showed a protective effect (OR = 0.97, p = 0.034).

Conclusions:

  • In Malaysian children, delivery by caesarean section is not a significant risk factor for developing asthma.
  • Family history of atopy and infant feeding practices are more critical determinants of childhood asthma.

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 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-II: Pathophysiology and Classification01:26

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

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:

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,...
