For the prospective cohort study, researchers used data from 30,239 participants in the Reasons for Geographic and Racial Differences in Stroke study. They defined neighborhood socioeconomic status using a score derived from census data and classified into quartiles.
Researchers also identified infection-and sepsis-related hospitalizations between 2003 and 2012. They found 3,054 hospitalizations for serious infections over a 6.5-year median follow-up.
The study shows infection incidence was lower for participants in the highest neighborhood socioeconomic status quartile (11.7 per 1,000 person-years) as compared with the lowest quartile (15.6 per 1000 person-years).
However, the researchers did not find an association between neighborhood socioeconomic status and sepsis among those hospitalized with infection.
