Evidence Based Practice : Aerobic Exercise and Major Depressive Disorder

Abstract

Mental health problems are international challenges that have a significant contribution in illness burden over the entire world (Blake, 2012). Major Depressive Disorder (MDD) is one of the common health problems, and is estimated to affect 121 million adults worldwide (World Health Organization [WHO], 2012). Projections for the year 2030 indicate that MDD will rank second only to coronary heart disease as a cause of illness burden over the entire world (WHO, 2012). Furthermore, WHO, 2012 reported that MDD currently represents a second health problem regarding disability caused by illness in the world.
