Obesity has become a major health concern in the U.S. and other countries as overweight and obesity rates have increased markedly since the early 1980s. The rise in children's obesity is a particular concern, because overweight children are more likely to become overweight adults, and because obese children are likely to suffer from associated medical problems earlier in life. Food marketing is among the postulated contributors to the rise in obesity rates. Food marketing to children has come under particular scrutiny because children may be more susceptible to marketing and because early eating habits may persist. Some researchers report that children's exposure to television advertising has been increasing along with the rise in children's obesity rates. This book presents a comprehensive analysis of the exposure of children to television advertising.
