Fitwits MD™: an office-based tool and games for conversations about obesity with 9- to 12-year-old children.

Background: Physician feelings of ineffectiveness and family-related barriers hamper childhood obesity discussions. Physicians desire appealing, time-efficient tools to frame and sensitively address obesity, body mass index, physical activity, nutrition, and portion size. Our university design-led coalition codeveloped tools and games for this purpose.
