“…Studies that compare SES disparities in health across countries have found that SES gradients in all-cause mortality ( Riva et al, 2007 , Mackenbach et al, 2008 , Meijer et al, 2012 ) and self-reported health ( Riva et al, 2007 , Maskileyson, 2014 ) exist across a range of health systems, and that the steepness of these gradients is largely comparable across countries despite differences in the universality of their publically funded health care ( Maskileyson, 2014 ). The important role of neighborhood and associated behavioral determinants of health in creating “health-wealth” gradients in mortality ( Stringhini et al, 2010 , Nandi et al, 2014 , Jonker et al, 2015 ) and survival ( Southern et al, 2005 , Shaw et al, 2014 ) has also been well-established across a range of settings.…”
