The book addresses the global public health issue of childhood obesity, with a particular focus on Taiwan, where rising obesity rates among children are increasingly concerning. It highlights the challenges that obesity poses to children's physical and mental well-being, which in turn negatively impact their quality of life. Drawing on data from Taiwan's National Health Administration, the book contrasts obesity rates between boys and girls and examines how global media influences body image perceptions. It explores the connections between childhood obesity and psychological issues such as low self-esteem and depression, prevalent in both Western and non-Western societies. Additionally, the research investigates how body mass index (BMI), socioeconomic status, and academic performance contribute to self-esteem in obese children. By examining childhood obesity through psychological, sociological, and cultural lenses, the book provides a comprehensive understanding of the issue. It also considers the potential negative effects of obesity on interpersonal relationships, academic achievement, and overall quality of life.
