Health and Disease in Adolescence

Authors: Nicola Reavley, George Patton, Susan Sawyer, Elissa Kennedy, Peter Azzopardi

Introduction:
Rising adolescent health problems, such as road traffic injuries (RTIs), mental disorders, and substance use disorders, are an increasing cause for concern in countries that have otherwise reduced maternal mortality and boosted child survival (Patton and others 2009). Moreover, with aging populations and a convergence to a disease burden dominated by noncommunicable diseases (NCDs) in later life; adolescent health risks, such as tobacco use, physical inactivity, obesity, substance use, and poor diet, assume greater significance (Jamison and others 2013). Adolescence is defined as ages 10–19. Chapter 1 of this volume describes the definitions used in this volume in greater detail (Bundy and others 2016).
