Investigating the relationship between neighborhood poverty and mortality risk: A marginal structural modeling approach

► Long-term neighborhood poverty measures are more strongly connected to mortality risk than single-point-in-time measures. ► MSM reveal a stronger relationship between neighborhood poverty and mortality risk than conventional naïve regression. ► The risk of mortality is not increased until neighborhood poverty reaches a threshold point. ► Sensitivity analysis indicate that statistically significant estimates were moderately robust to omitted variable bias.
