    Health Canal - 05/01/2013

    Working with a team led by Stephen Intille from Northeastern University that develops mobile phone health technology, the USC investigators sent 120 children 20 electronic surveys over a four-day period that included two weekdays and two weekend days. The surveys were sent randomly over phones supplied by the team whose only feature was to prompt the youngsters and accept answers to the survey, Liao said. Sedentary behavior was divided into productive (homework, reading) or leisure-oriented  activity (playing video games, watching TV).
