RECORD GPS Study: the pilot test started in January 2012

Posté le 27/07/2012 10:24

In the RECORD GPS Study, participants are asked to wear on a belt at the hip a GPS and an accelerometer from wake up to bedtime for 7 consecutive days.

After a preprocessing of the resulting data by automatic algorithms, participants are surveyed with a computer application that allows one to visualize on a map the trajectories of mobility, to confirm or modify the information imputed by the algorithms, and to answer to questions on the activities practiced at the different places and on the transportation modes employed.

Based on these data, we will be able (i) to describe precisely the transportation habits of participants; (ii) to examine the extent to which active transportation contribute to the total physical activity of people; (iii) to assess the effects of transportation habits on health, especially on body weight and fat; and (iv) to identify the characteristics of the environments that influence mobility and transportation habits, and in turn health.

Moreover, the trajectories of mobility collected by GPS will allow us to determine exposures to different obesogenic characteristics of the environment that take into account the multiple contexts of daily lives.

The study is conducted in close collaboration with the University of Montreal and received financial support from institutions from the health field (IReSP, INPES, ARS of Ile-de-France) and from the transportation field (DGITM and CERTU from the Ministry of Ecology, STIF, RATP, Direction of Transportation of the Ile-de-France Regional Council).

On July 24 2012, 76 participants had already been included in the GPS Study.
