What this trial studies

This observational study follows 250 urban children and adolescents with asthma and 60 without asthma over a one-year period. Participants aged 6-17 will be monitored for their asthma symptoms and cold symptoms, with scheduled visits throughout the year. The study aims to establish phenotypic characteristics and gather data on the impact of asthma and respiratory symptoms in this population. Participants with asthma must be on daily controller therapy, while those without asthma must not have used asthma medications in the past year.

Who should consider this trial

Good fit: Ideal candidates are urban children and adolescents aged 6-17 with a diagnosis of asthma requiring daily controller therapy or those without asthma who meet specific criteria.

Not a fit: Patients who do not meet the age or residency requirements, or those who have used asthma medications in the past year, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of asthma in children and lead to improved management strategies.

How similar studies have performed: Other studies have shown success in understanding asthma phenotypes in children, making this approach both relevant and potentially impactful.
