Obesity? Diabetes? Move to a better neighbourhood

We know that neighbourhood characteristics influence health but we don't know quite how or how much. Here's a study which used a random lottery to give selected low income families a voucher to move to a less-impoverished neighbourhood. Apparently it shows that

'low-income women with children who move from high-poverty to lower-poverty neighborhoods experience notable long-term improvements in some aspects of their health, namely reductions in diabetes and extreme obesity.'

Yes I think so too, it would be a good idea to start eradicating neighbourhoods characterised by extreme poverty in the first place. I can see how doing that might reduce poor health and therefore costs to the taxpayer.

It would be nice not to need studies like this, but in the meantime it's important to have the evidence. And I like the idea of the randomised study.
