NEW YORK - TEENAGERS love their cell phones, and researchers may be able to take advantage of that fact to improve their health, a pilot study suggests. In a study of 15 teenage girls, the investigated looked at the feasibility of using GPS-enabled cell phones to track adolescents' whereabouts when they were away from home or school. The researchers found that the girls were happy to take the phones with them wherever they went, and that the GPS accurately plotted their travels over one week. The point of the surveillance was not to pass on information to curious parents, however. Instead, the researchers hope to use the technology to study the health risks that teenagers typically face, and possibly to intervene. -Curtosy Strait times newspaper
