The free running asthma screening test (FRAST) effectively identifies children with unrecognized exercise-induced bronchospasm. This simple test is a cost-effective method for early asthma detection in schools.

Area of Science:

  • Pediatric Pulmonology
  • Respiratory Medicine
  • School Health

Background:

  • Exercise-induced bronchospasm (EIB) is common in children.
  • Early identification of EIB is crucial for effective asthma management.
  • Current screening methods may miss many affected children.

Purpose of the Study:

  • To evaluate the effectiveness of the free running asthma screening test (FRAST) in identifying children with EIB.
  • To compare FRAST results with traditional asthma questionnaires.
  • To assess the feasibility and cost-effectiveness of FRAST in a school setting.

Main Methods:

  • 503 schoolchildren aged 6-12 years underwent the FRAST.
  • FRAST involved measuring peak expiratory flow rate (PEFR) before and after a 5-minute run.

  • An abnormal result was defined as >15% PEFR fall in at least two post-exercise readings.

    • Main Results:

    • 14% of children failed to complete the FRAST.
    • 10 previously undiagnosed asthmatics were identified among those with abnormal FRAST results.
    • FRAST identified children with unrecognized EIB missed by questionnaires.

    Conclusions:

    • The FRAST is an acceptable and feasible screening tool for identifying potential asthmatics in schools.
    • FRAST is a cost-effective method for detecting unrecognized exercise-induced bronchospasm.
    • Approximately one child per school class may have undiagnosed EIB.
