“…A number of studies have revealed that limited HL is related to worse physical and mental health and poor healthcare utilization (Williams et al, 1998a;Gazmararian et al, 1999;Kalichman et al, 2000;Baker et al, 2002;Schillinger et al, 2002;Scott et al, 2002;Wolf et al, 2004;Howard et al, 2005;Wolf et al, 2005;Davis et al, 2006;Sudore et al, 2006;Baker et al, 2007;Laramee et al, 2007;Bennett et al, 2009;Tokuda et al, 2009;Berkman et al, 2011b). However, those studies focussed mainly on functional HL (Williams et al, 1998a,b;Kalichman et al, 2000;Schillinger et al, 2002;Laramee et al, 2007;Guerra et al, 2008;Chaudhry et al, 2011).…”
