“…In an attempt to explain these divergent trends, research has focused on pathways that account for persistence in and expansion of health inequalities. Some of these include mediators such as stress, social support, and preventive as well as risk behaviors (Engdahl and Tambs 2010;House et al 1990;Marmot and Siegrist 2004;Petrelli et al 2006;Tang, Chen, and Krewski 2003). Some research suggests pathways can operate from early life onward, implicating both childhood and adult SES as determinants of health in old age (Elo and Preston 1997;Galobardes, Lynch, and Davey Smith 2004;Galobardes, Lynch, and Smith 2008;Galobardes, Smith, and Lynch 2006;Hayward and Gorman 2004;Luo and Waite 2005;Preston, Hill, and Drevenstedt 1998;Smith and Hanson Forthcoming).…”
