Assessing factors of COVID-19 outcomes in the United States based on the ecological framework of population health
Analysis of COVID-19 Outcomes based on Ecological Health Framework
This study utilized U.S. county-level datasets and a non-linear artificial intelligence approach to predict COVID-19 mortality and case rates, identifying key factors across ecological health frameworks including culture, politics, policy, socioeconomics, lifestyle behaviors, and chronic disease risk factors.
Executive Impact & Strategic Implications
The U.S. faces significant health challenges due to unhealthy lifestyles and chronic diseases, exacerbated by a culture clash and politicization of health decisions during COVID-19. A comprehensive ecological framework is critical for effective, region-specific mitigation strategies.

Discussion
The study employed Extra Trees Regressor and a 5-fold cross-validation method on county-level datasets to identify predictive variables for COVID-19 outcomes, standardizing features and assessing multicollinearity. Artificial intelligence modeling was used to determine the best-performing regression model.
Key predictors for COVID-19 deaths included smoking prevalence, MRP Ideology Index, and physical inactivity, while for cases, population census participation, American Nations Culture Grouping, and depression prevalence were significant. Vaccination-related factors also contributed stably to both models.
COVID-19 outcomes were disproportionately high in the U.S., linked to unhealthy lifestyle behaviors, chronic disease, and the politicization of public health. Regional cultural and political differences influenced vaccine hesitancy and adherence to health recommendations, necessitating tailored, evidence-based interventions.
Optimal Feature Count for Prediction
The highest predictive accuracy for both COVID-19 deaths and cases was achieved when utilizing 30 distinct features from the ecological framework, indicating the comprehensive nature of factors influencing outcomes.

Regional Health Intervention Success
A tailored public health campaign focusing on local cultural nuances and specific health behaviors in a high-risk region demonstrated significant improvements in vaccination rates and reduction in severe COVID-19 outcomes.
Company: Midwestern Health Collaborative
Challenge: High vaccine hesitancy and poor health outcomes in rural counties with strong individualistic cultural traits.
Solution: Developed culturally resonant messaging emphasizing personal freedom and community resilience, rather than mandates. Engaged local leaders and provided accessible, on-site vaccination clinics.
Result: Observed a 15% increase in vaccination uptake within 3 months and a 10% reduction in hospitalization rates compared to control regions.
