Research – Quantitative

To make an effective impact on community health, public health practices, programs and policies must be informed by accurate research and analysis. The Public Health Institute works to foster health, well-being, and quality of life through rigorous quantitative research guided by the principles of health equity, environment, education, and economic contexts. By exploring statistical associations between variables and finding differing patterns in population health outcomes, our programs help to advance research and practice, evaluate the cost of health inequities and disease, design successful programs and interventions, and improve health outcomes in communities.
