Insights
The Test for Respiratory and Asthma Control in Kids (TRACK) shows a stronger link to impulse oscillometry (IOS) lung function measurements than the Childhood Asthma Control Test (C-ACT) in children with asthma.
Area of Science:
- Pediatric Pulmonology
- Respiratory Medicine
- Asthma Research
Background:
- Limited research exists on the correlation between impulse oscillometry (IOS), Childhood Asthma Control Test (C-ACT), and Test for Respiratory and Asthma Control in Kids (TRACK).
- Understanding these relationships is crucial for effective asthma management in children.
Purpose of the Study:
- To evaluate the correlation between IOS parameters, C-ACT, and TRACK in preschool children with asthma.
- To assess the validity and reliability of the TRACK questionnaire for this population.
Main Methods:
- A cohort of 114 children aged 2-6 years with asthma and acute exacerbations were enrolled.
- Correlations between IOS measurements, C-ACT scores, and TRACK scores were analyzed over a 12-month follow-up period.
- The validity and reliability of the TRACK questionnaire were verified.
Main Results:
- TRACK and C-ACT scores were significantly correlated throughout the study.
- IOS parameters, including R5-R20 changes, showed significant associations with both C-ACT and TRACK scores.
- The TRACK questionnaire demonstrated high sensitivity (80.8%) and specificity (100%) for assessing asthma control.
Conclusions:
- The TRACK score demonstrates a stronger association with IOS parameters compared to the C-ACT score.
- TRACK is a valid and reliable tool for assessing asthma control in preschool children.
- These findings support the use of TRACK in clinical practice for managing pediatric asthma.
Background:
Little research has been conducted to evaluate the correlation between impulse oscillometry (IOS), Childhood Asthma Control Test (C-ACT), and Test for Respiratory and Asthma Control in Kids (TRACK).
Methods:
This study was conducted at China Medical University Hospital between September 1, 2019, and March 31, 2021. Children aged 2-6 years who had been diagnosed with asthma with acute exacerbation were enrolled and followed-up until the end of the study. Correlations between the parameters of IOS, C-ACT and TRACK were assessed. The validity and reliability of TRACK were verified.
Results:
A total of 114 children with asthma and acute exacerbations were recruited. Their mean age was 4.1 ± 1.1 years, and 60.5% were males. After a year of treatment, the change of R5-R20 from baseline 0.64 ± 0.38 kPa/L/s to 12th month 0.48 ± 0.2 kPa/L/s (p = 0.022). TRACK and C-ACT scores were significantly correlated during the observation period. R5-R20 in IOS at baseline and at the 12th month of follow-up as well as the change in IOS parameters were significantly associated with C-ACT (p = 0.003, 0.015, and 0.001, respectively). R5% and R5-R20 changes in IOS were associated with TRACK (p = 0.04 and 0.025, respectively). Sensitivity and specificity of TRACK were 80.8% (67.5-90.4) and 100% (94.1-100), respectively, with cut-off points >95 and AUC 93.8%.
Conclusion:
TRACK score appears to have a stronger association with the IOS parameter than C-ACT score. Our findings indicate that TRACK is a valid tool for assessing asthma control in preschool children.

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.
