Public health·2005

Allergy significantly impairs lung function in schoolchildren, leading to lower spirometry results. This study highlights the negative impact of allergies on respiratory health in children.

Area of Science:

  • Pediatric Pulmonology
  • Allergy and Immunology
  • Epidemiology

Background:

  • Allergies are common in children and can affect respiratory health.
  • Spirometry is a key tool for assessing lung function in pediatric populations.
  • Understanding the impact of allergy on lung function in schoolchildren is crucial for early intervention.

Purpose of the Study:

  • To quantify the effect of clinically diagnosed allergy and allergy confirmed by skin testing on lung function in 10-11 year old schoolchildren.
  • To compare lung function indices between allergic and non-allergic children.
  • To determine the prevalence of obstructive syndrome in relation to allergy status.

Main Methods:

  • A cross-sectional study involving 1048 schoolchildren aged 10-11 years in Krakow.

  • Lung function assessed using spirometric indices including VC, FVC, FEV1, FEF25-75%, and PEFR.
  • Allergy data collected via parental questionnaires and medical record review for skin test results.

    • Main Results:

    • Allergic children showed significantly lower mean values for most spirometric indices (except VC and FVC) compared to non-allergic children.
    • Allergy diagnosis, both clinical and skin-test confirmed, was more frequent in boys.
    • The prevalence of obstructive syndrome (FEV1/FVC < 80%) was higher in children with diagnosed allergies (7.2%–8.5%) than in non-allergic children (2.9%).

    Conclusions:

    • Allergy has a significant negative impact on various measures of lung function in schoolchildren.
    • Allergic conditions are associated with an increased prevalence of obstructive respiratory patterns in this age group.
    • Findings underscore the importance of allergy management for maintaining optimal respiratory health in children.
