Eur J Epidemiol. 2012 Jul;27(7):561-6. doi: 10.1007/s10654-012-9708-4. Epub 2012 Jun 29.


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.
