Résumé : | [BDSP. Notice produite par INIST-CNRS 7l9lR0xA. Diffusion soumise à autorisation]. An investigation in a randomized population-based Swedish study with 564 participants aged 18-80 years showed that mean physical activity levels obtained using short message service (SMS) by means of cell phones (n=171) were equal to corresponding levels obtained when sending identical questions by web (n=182) or paper (n=211). The response rates were similar for the SMS, web and paper groups. |
