Socioeconomic and race/ethnic patterns in persistent infection burden among U.S. adults

Making Education Easy

From Māori Health Review Issue 20

  • Zajacova A et al
Summary:

This report presents an analysis of data from the National Health and Nutrition Examination Survey III (n=19,275) for adults aged 17–90 years, in an investigation into how multiple persistent infections cluster within individuals and how this clustering varies by socioeconomic position and race/ethnicity in U.S. adults. A positive correlation was observed for seroprevalence of individual persistent infections, suggesting common factors related to exposure or susceptibility. In all multiple indicator multiple cause models, strong and significant independent predictors of infection burden in U.S. adults included education, income, and race/ethnicity.

Comment:
Important that we don’t look at the burden of persistent infections among disadvantaged people as ‘their problem’. I can imagine some people saying ‘it’s because they didn’t see the doctor for antibiotics’ or ‘it’s their living conditions’. Instead, the paper provides evidence for a biological cause of health disparities that occur when there is disadvantage at the system level and therefore even further reason to ensure good quality primary care for those at risk of chronic infection (Māori, Pacifica, higher levels of deprivation).
