Describe what makes your study design unique and
innovative, compared to other studies investigating the relationship
between exposure to air pollution and the incidence of asthma. In your
answer, consider novel approaches to measuring exposure or outcome,
innovative methods for addressing confounding or bias, or creative ways
of sampling or recruiting study participants. Explain how your design
could advance our understanding of this relationship or lead to novel
interventions to reduce the burden of asthma in affected populations.
