Childhood Overweight and the Built Environment: Making Technology Part of the Solution rather than Part of the Problem

The changing nature of how children engage with their physical environment is one factor in the dramatic increase in childhood overweight. Children today are engaging much less with the world outside their homes in terms of physical activity and much more in terms of eating. Technological innovations in media have contributed to these changes, keeping children inside and sedentary during more of their playtime and exposing them to highly coordinated advertising campaigns. But researchers are increasingly looking to technology for solutions to understand how children interact with their built environments and to make changes that promote healthy living. This article reviews many of these innovations, including the use of geospatial technologies, accelerometers, electronic food and travel diaries, and video games to promote physical activity and healthy eating. It also explores some of the other possibilities for harnessing the potential of technology to combat the childhood overweight epidemic.
