Text messages used to encourage kids to diet, exercise

null Every day for eight weeks, the families of 18 children between 5 and 13 were sent text messages asking how much time the child had spent exercising that day, how much time was spent in front of a TV or computer, and whether the child had any sugary drinks that day.

Another group kept paper diaries. A third group kept no log.

The study found that families in the text messaging group had a decline in TV and computer time.

The study is in the Journal of Nutrition Education and Behavior.
