The way I read this is, that because of socio-economic effects, black people have a different lifestyle and because of this we see the ageing occur earlier. Am I reading that correct?
Why diden't they control for variables such as average or mean income if they believe that's a spurious correlation? We know people who are more wealthy on average live longer, eat more healthy, get more exercise, read more books etc.
