Which of the following actions target social determinants of health in an improvement project on...

Explanation: Social determinants of health (SDOH) are non-medical factors that influence health outcomes, such as environmental conditions, socioeconomic status, and access to resources. In an asthma control improvement project, targeting SDOH involves addressing external factors like air quality or geographic disparities that exacerbate asthma. Mapping asthma patient zip codes against environmental air quality data (B) directly addresses SDOH by identifying correlations between environmental factors and asthma prevalence or severity, enabling targeted interventions. Options A, C, and D focus on clinical or demographic factors, not SDOH.
