Background: In a recently published article, it was suggested that governance was the significant
structural factor affecting the epidemiology of HIV. This suggestion was made notwithstanding the
observed weak correlation between governance and HIV prevalence (r = .2). Unfortunately, the
paper raised but left unexamined the potentially more important questions about the relationship
between the broader health of populations and structural factors such as the national economy and
physical infrastructure.
Methods: Utilizing substantially the same data sources as the original article, the relationship
between population health (healthy life expectancy) and three structural factors (access to
improved water, GDP per capita, and governance) were examined in each of 176 countries.
Results: Governance was found to be significantly correlated with population health, as were GDP
per capita, and access to improved water. They were also found to be significantly correlated with
each other.
Conclusion: The findings are discussed with reference to the growing interest in structural factors
as an explanation for population health outcomes, and the relatively weak relationship between
governance and HIV prevalence
