Hypothesis
To examine the association of air pollutants with hospital admission for childhood asthma in Hong Kong.
Conclusion
Ambient levels of PM10, PM2.5, NO2 and O3 are associated with childhood asthma hospital admission in Hong Kong.
Supporting Evidence
- An increase in asthma admission rate of 5.64% at lag 3 for NO2.
- An increase in asthma admission rate of 3.67% at lag 4 for PM10.
- An increase in asthma admission rate of 3.24% at lag 4 for PM2.5.
- An increase in asthma admission rate of 2.63% at lag 2 for O3.
Takeaway
Air pollution can make kids with asthma sicker and lead to more hospital visits.
Methodology

Potential Biases
