“…The special characteristic of these differences is that they do not exist only between the highest and the lowest group but typically show a gradient across the socio-economic hierarchy (Huijts, Eikemo, & Skalická, 2010;Marmot, Ryff, Bumpass, Shipley, & Marks, 1997;Townsend & Davidson, 1982). Similarly, studies including home-dwelling individuals in the age range of 60 to 85 have demonstrated a heavier burden of diseases (CVD, arthritis, depression and the total number of diseases), and a higher disability among those with low education, poor financial assets or low occupational status (Chandola, Ferrie, Sacker, & Marmot, 2007;Laitalainen, Helakorpi, Martelin, & Uutela, 2010;Ramsay, Whincup, Morris, Lennon, & Wannamethee, 2008;Rostad, Deeg, & Schei, 2009;Rueda, Artazcoz, & Navarro, 2008;Schöllgen, Huxhold, & Tesch-Römer, 2010;Sulander, Rahkonen, Nummela, & Uutela, 2009), and a consistent association between poor self-rated health and low occupational status or lack of means McMunn, Nazroo, & Breeze, 2009). Among people aged 80 years or older, poor selfrated health and functional limitations have been associated with low socio-economic status (Arber & Cooper, 1999;Huisman, Kunst, & Mackenbach, 2003;Rostad et al, 2009).…”
