Pittsburgh today is joining a federal anti-obesity program for children that pushes subtle changes at home.

National Institutes of Health officials announced that the We Can! program is teaming up with the Association of Children's Museums, as well as the cities of Boston, Pittsburgh and Las Vegas, the three largest cities yet to adopt the 2-year-old initiative.

We Can! -- short for Ways to Enhance Children's Activity & Nutrition -- is aimed at kids 8-13 and pushes commonsense steps to keep off weight, such as eating fewer high-fat foods, exercising more and spending less time staring at television and computer screens.

A community that officially commits to We Can! agrees to host numerous parent and youth events that promote the program. Besides the three cities being announced today, five others, including Armstrong County, Pa., already are official We Can! communities. About 450 communities in 44 states are using some part of the program.
