Old age is a period during which an individual is no longer actively involved in production and experiences loss of role and status. Moreover, in this period physical strength diminishes; dependency, accident risk, disability and medication consumption increase; body adjustment to external world and its resistance to stressors decrease; body becomes more prone to illnesses because of immune deficiency; as a result, it suffers from many degenerative and chronic diseases. Old age is also a public health issue that concerns both health system and socio-economic systems, and requires multi-sectoral and multi-disciplined service (Terakye & Guner, 1997).
