The Pediatric Asthma Risk Score Can Help Predict Asthma Development in Children

The multi-cohort study being presented at the 2023 AAAAI Annual Meeting examined a diverse population across the United States.

Milwaukee, WI – Researchers have confirmed the effectiveness of the Pediatric Asthma Risk Score (PARS) after validating its use with diverse cohorts from across the United States. The results are being presented in full during the 2023 Annual Meeting of the American Academy of Allergy, Asthma & Immunology (AAAAI).

“If we hope to initiate early prevention strategies, it is essential that we predict asthma as early as possible,” said Jocelyn M. Biagini, PhD, primary author of the study. “PARS is a continuous score that was developed to predict early-life asthma. We wanted to validate the results in cohorts that were more diverse than in original studies.”

PARS was compared to the Asthma Predictive Index (API) in ten cohorts, which included 5,674 children. These cohorts were diverse in terms of race, ethnicity, sex, cohort type, missing data and birth decades. Researchers performed meta-analysis across all ten of the cohorts. PARS and API were applied in each cohort, and researchers compared the ability of both tools to predict asthma’s development between the ages of five and ten.

Researchers found the PARS area under the curve (AUC) was higher than the AUC of the API across nine cohorts out of the ten. The PARS AUC didn’t change based on the cohort type. “Essentially what we saw was that the original PARS scoring was similar to scoring in the new, more diverse cohorts,” said Dr. Biagini. “This validates our previous results and could lead to PARS ultimately becoming a new quantitative gold standard in pediatric asthma risk prediction.”
