What Comes First? Diabetes or Socio-economic Class?

London, England
The article below and linked discusses the relationship between chronic illness and low-er economic status or as it is called in the article "material deprivation."

"Researchers in London have identified a link between increased hospital admission rates for chronic diseases and high levels of material deprivation in the capital. The research published in this month's Journal of the Royal Society of Medicine, shows how admission rates for chronic diseases such as asthma and diabetes are linked to the level of material deprivation in the surrounding area, and not to poor care by GPs serving them."

and

More importantly it also illustrates that high admission rates for chronic diseases may not be down to poor primary care. If a PCT is in a materially deprived area, higher admission rates for chronic diseases could be inevitable."

(PCT's are NHS organisations which focus on managing the health of a local population.)

Interesting. Not sure what the Royal Society of Medicine is aiming for here. It is the chicken and egg dilemma. Which comes first? Education and preventative care or large, poor diabetic population?
