Introduction: Intracerebral hemorrhage (ICH) has been shown to display variations in geographic distribution, age, and racial predisposition. Understanding spatial disparities in the association between socioeconomic factors and ICH is critical to target public health initiatives aiming to mitigate or prevent this disease. We aimed to describe the historical trends of mortality due to ICH during a time of massive expansion in New Orleans (1880-1915). This analysis is part of the New Orleans Mortality Project which brings together historical perspective and new spatiotemporal approaches to understand how health, environment, and socioeconomics impacted urban and community development in New Orleans, 1880-1915.
Methods: As part of the New Orleans Mortality Project, we constructed a 50,000-person mortality database from death certificates, a 40,000-record property value database from tax ledgers, and base-level population datasets from city directories. 1507 patients died of ICH (age 60.2 ± 15.8; 54.4% Male; 69.2% White). We built historical address locators to geocode these datasets. We used geographically weighted regression to analyze the connections among mortality due to ICH, all-cause mortality, population density, age, socioeconomics, and environmental factors. Eight time periods were analyzed at 5-year intervals from 1880-1915.
Results: The results of this analysis will reveal processes of the mortality transitions and the evolution and effects of urban disease terrains on individual and community development. Preliminary analyses have shown evolving areas of increased rates of death due to ICH (corrected for all-cause mortality and population density) along the periphery of population growth into areas of low income. Further analysis is required to describe the relationship due to race, sex, and age.
Conclusions: Mortality due to ICH (although a heterogeneous diagnosis) has ties to socioeconomic status as evident by its spatiotemporal evolution during the expansion and urban sprawl of New Orleans, 1880-1915. This relationship can be extrapolated and further compared to modern day trends.
Patient Care: By improving physician understanding of the historical ties of ICH to socioeconomic status and urban sprawl.
Learning Objectives: By the conclusion of this session, participants should be able to: 1) Describe the connection of ICH mortality to socioeconomic status, 2) Describe the association with sex, age, and race, 3) Be able to extrapolation the analysis to their own area
