Analysis of Premature Death Rates in Texas Counties: The Impact of Air Quality, Socioeconomic Factors, and COPD Prevalence

TL;DR

This study investigates how air quality, socioeconomic status, and COPD prevalence influence premature death rates in Texas counties, highlighting COPD as a key predictor and emphasizing integrated health interventions.

Contribution

It provides a comprehensive analysis of multiple risk factors affecting premature mortality, with novel insights into COPD's significant role and complex air quality relationships.

Findings

COPD prevalence strongly predicts premature death rates.

Socioeconomic factors negatively correlate with mortality.

Air quality has complex indirect effects.

Abstract

Understanding factors contributing to premature mortality is critical for public health planning. This study examines the relationships between premature death rates and multiple risk factors across several Texas counties, utilizing EPA air quality data, Census information, and county health records from recent years. We analyze the impact of air quality (PM2.5 levels), socioeconomic factors (median household income), and health conditions (COPD prevalence) through statistical analysis and modeling techniques. Results reveal COPD prevalence as a strong predictor of premature death rates, with higher prevalence associated with a substantial increase in years of potential life lost. While socioeconomic factors show a significant negative correlation, air quality demonstrates more complex indirect relationships. These findings emphasize the need for integrated public health interventions that prioritize key health conditions while addressing underlying socioeconomic disparities.
