Trends in asthma-related paediatric mortality.

Asthma is a leading cause of paediatric mortality. This study aims to elucidate trends in paediatric mortality over time. Using US Centers for Disease Control (CDC) WONDER data, we conducted a cross-sectional analysis of paediatric asthma-related mortality between 1999 and 2023, overall and stratified by year, age, sex, race and region. Negative binomial regression was used to test the linear temporal trend and conduct group comparisons in asthma-related mortality rates. Over the study period, there were 5357 asthma deaths. The mortality rate was 3 per 1 000 000 children and rates remained stable over this period. Asthma mortality was higher in males, children 10-19 years (compared to children 5-9 years) and black (relative to white) children. Advances in the treatment of paediatric asthma should be aimed at reducing mortality and addressing differential health outcomes among black children.
