Childhood Asthma Exacerbations Linked to Black Carbon in Xiamen, 2020-2023

Xiamen, China, is the focus of this dataset containing 3,440 cases of acute childhood asthma exacerbations from January 2020 to December 2023. The data was used in a case-crossover study to investigate associations with short-term exposure to atmospheric black carbon and other pollutants. The study was authored by Yating He and published on figshare in 2026.

Use Cases

• Modeling the association between short-term black carbon exposure and acute asthma events based on case-crossover design.
• Analyzing interaction effects between black carbon and PM2.5 components like sulfate and nitrate.
• Conducting stratified risk analysis by age, sex, and season, as indicated in the study description.
• Evaluating multi-pollutant exposure effects using statistical methods like Bayesian kernel machine regression (BKMR).

Strengths

• Contains 3,440 cases of childhood asthma exacerbations.
• Covers a four-year time period from 2020 to 2023.
• Includes data on multiple pollutants (black carbon, PM2.5, sulfate, nitrate, ammonium, organic matter) and meteorological factors.
• Employs a case-crossover study design with a 7-day control period for each case.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying environmental data is unknown, which may limit suitability assessment.
• Data is geographically limited to Xiamen, China, which may affect generalizability.
