Lifestyle diseases and related conditions present a major healthcare challenge for children, posing a significant threat to their well-being. The Editors have compiled chapters to present a multicentric approach to the subject. This book is an insightful reference on lifestyle diseases and its management in adolescents. It includes twelve topics with a focus on physical, emotional and behavioral aspects of lifestyle diseases. Starting with an introduction to lifestyle issues that can manifest into disease states, the book progresses to advanced topics, including emotional and cognitive developments, effects of mass media ranging from emotional and cognitive health, nutrition requirements and eating disorders, physical inactivity, eating and sleeping patterns, drug and alcohol-abuse, social behavior, anxiety and mental health. The book highlights the risk factors and determinants of these diseases, and where an immediate intervention is needed.
