In Philadelphia, rates of obesity among teens are above the national average. A new study led by Clare Lenhart, a public health doctoral candidate at Temple, examines what Philadelphia public high school students are doing to shed pounds. While most of the children surveyed expressed that they were trying to lose weight, a majority were engaged in counter-productive behavior such as smoking, drinking sodas and playing video games. "It could be that they are interested [in weight loss] but don't know how [to do it]," said Lenhart. "There's a number of implications for education and programming that could build on this data."
