“…Studies on the former have found that both socio-demographic characteristics and socioeconomic position predict disability retirement: High age is a strong predictor (Gjesdal et al, 2004;Leinonen et al, 2011;Bruusgaard et al, 2010;Støver et al, 2012), as well as being a woman (Samuelsson et al, 2012;Krokstad and Westin, 2004;Bruusgaard et al, 2010;Støver et al, 2012), or unmarried (Leinonen et al, 2011;Samuelsson et al, 2012). Lower socioeconomic position has consistently been found to be strongly negatively associated with disability retirement, regardless of what measure of socioeconomic position that has been used: occupational class (Krokstad and Westin, 2004;Leinonen et al, 2011;Samuelsson et al, 2012), education (Gravseth et al, 2007;Samuelsson et al, 2012;Leinonen et al, 2011;Bruusgaard et al, 2010;Støver et al, 2012), income (Gjesdal et al, 2004;Leinonen et al, 2011), and unemployment (Leinonen et al, 2011;Støver et al, 2012). Studies on the socioeconomic determinants of impairment or disability per se are scarcer, but their findings suggest, unsurprisingly, that the same factors found to predict disability retirement also predict (self-reported) impairment and disability (Pascual and Cantarero, 2007;Reinhardt et al, 2013;Melo and Valdes, 2011).…”
