“Poverty, urban-rural classification and term infant mortality: a population-based multilevel analysis” examined data from the National Center for Health Statistics to try and estimate the independent effect of poverty and urban-rural classification on term infant mortality.
The study found:
“High poverty and very rural counties remained associated with term infant mortality independent of individual maternal sociodemographic, health and obstetric factors. Interventions should focus on contextual factors such as economic environment and availability of health and social services in addition to individual factors to reduce term infant mortality.”
