Tracking Myself: Assessing the Contribution of Mobile Technologies for Self-Trackers of Weight, Diet, or Exercise.

For individuals trying to lose or maintain weight, self-tracking their weight, diet, or exercise is important. In the past, different tracking modes have been examined, like paper and pencil, memory, or personal digital assistants. But the recent advancement and adoption of mobile technologies could also result in easier and simpler self-tracking. However, little is known about self-trackers, their tracking modes, and the absolute or relative contribution of each tracking mode at the population level. This study fills this gap by (a) comparing self-trackers' characteristics across tracking modes and against nontrackers and (b) testing the relationship between mobile self-tracking and tracking outcomes using a representative sample of data from the Pew Internet and American Life Project from 2012. Controls in the model include demographics, technology use, and health indicators. Results suggest that mobile self-trackers are younger and more educated and that mobile self-tracking is a positive contributor and the best tracking mode.
