Insights

Infants with recurrent asthma-like symptoms are frequently hospitalized. Maternal smoking during pregnancy and early wheezing onset increase admission risk, while breastfeeding and higher socioeconomic status offer protection.

Area of Science:

  • Pediatrics
  • Respiratory Medicine
  • Epidemiology

Background:

  • The prevalence and risk factors for infant hospitalization due to asthma/wheezing are not well-understood.
  • This knowledge gap contrasts with existing data for older children and adults.

Purpose of the Study:

  • To determine the prevalence of hospital admissions for wheezing exacerbations in infants with recurrent asthma-like symptoms.
  • To identify factors associated with these hospitalizations.

Main Methods:

  • A cohort of 2,079 infants (12-18 months) with recurrent asthma-like symptoms was studied across 11 South American centers.
  • Data were analyzed using descriptive statistics and multivariate logistic regression.

Main Results:

  • The prevalence of hospital admission for wheezing was 29.7%.
  • Risk factors included severe wheezing episodes, physician-diagnosed asthma, inhaled corticosteroid use, maternal smoking during pregnancy, and early wheezing onset (first trimester).
  • Protective factors included breastfeeding for at least 4 months, higher maternal education, and higher household income.

Conclusions:

  • Infants with recurrent asthma-like symptoms experience high hospitalization rates.
  • Maternal smoking, early-life viral respiratory illness, and disease severity are key risk factors.
  • Preventive strategies should focus on managing exacerbations, promoting breastfeeding, and avoiding smoking during pregnancy.

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

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: 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.
