Key result
Rural residency links to worse CV risk profiles than urban areas, potentially explaining mortality gradients.
Why the study?
The prevalence of cardiovascular risk factors among rural inhabitants compared to urban citizens and their role in mortality gradients is not fully understood and requires further investigation.
Rural populations, particularly in Russia, may have a less benign cardiovascular risk factor profile compared to urban populations, contributing to rural-urban mortality gradients.
May warrant rural-focused CV screening in Russia; leaves open whether risk profiles drive mortality gradients.
The review presents with the literary data on the prevalence of risk factors (RF) of cardiovascular diseases among inhabitants of rural areas comparing to citizens from the point of view explaining the mortality gradients between rural and city inhabitants in many countries in the world. It is shown that gradients of RF prevalence among rural inhabitants and citizens are oppositely directed and might change with time. In Russia in general the profile of RF among rural inhabitants is less benign comparing to citizens, that may explain mortality gradient. This issue demands further investigation.

Kontsevaya et al. (2016) conducted a review in Cardiovascular diseases. Rural residency vs. Urban residency was evaluated on Prevalence of cardiovascular risk factors. Rural residency is associated with a less benign profile of cardiovascular risk factors compared to urban residency in Russia, potentially explaining the observed mortality gradient.
