“…Evidences from both developed and developing countries show that older people are at much higher risk of multiple co-morbidities (Gijsen et al, 2001;Khanam et al, 2011;Salisbury, Johnson, Purdy, Valderas, & Montgomery, 2011;Salive, 2013;van den Akker, Buntinx, Metsemakers, Roos, & Knottnerus, 1998;Walker, 2007). Multiple morbidities have been proven to be directly associated with adverse health outcomes such as reduced physical functions (Fried, Bandeen-Roche, Kasper, & Guralnik, 1999;Kadam & Croft, 2007), reduced quality of life (Fortin et al, 2004), poor selfrated health (Galenkamp, Braam, Huisman, & Deeg, 2011), and mortality (Hoeymans, Feskens, Kromhout, & van den Bos, 1999).…”
