Global health issues have become an increasing worldwide controversy in the past four decades. The most significant health issues are communicable diseases and non-communicable diseases. The WHO Global status report shows that particularly the non-communicable disease is a growing global burden, and it is responsible for 63 percent of 57 million deaths that occurred in 2008. The majority of these deaths were attributed to cardiovascular diseases, diabetes, cancers and chronic respiratory diseases. Not only is this an unprecedented rate, but also a major concern due to the prediction put forward that non-communicable diseases will contribute to 80 percent of the global disease burden by 2020, resulting in 70 percent death in developing countries, compared with less than half today (WHO, 2011). In addition, the World Economic Forum in 2009 demonstrates that many threats to today's global economic development such as fiscal crises, natural disasters, pandemic influenza and non-communication diseases and NVDs, as the most severe one are most likely to be realized and potentially more detrimental than others (New England Journal of Medicine, 2010, 363:1196-1198) . Among non-communicable diseases, special attention is devoted to mental health problem, obesity, cardiovascular diseases and diabetes. This will be followed by a more specific description of the problem and a more detailed presentation of the relationship among them.
Depression is one of the characteristic problems among the primary mental diseases that affect nearly 350 million people with estimation (WHO, 2012). First, depression is one kind of mental disorder which can be distinguished from usual mood instabilities inducing a constant feeling of grief for one or two weeks and meddle in the capability of functioning at home, school or work (WHO, 2012). In Akiskal’s (2008) study, the incidence of depressive...
