AB  - Physical inactivity is one of the four leading risk factors for global mortality. 
      Accurate measurement of physical activity (PA) and in particular by physical 
      activity questionnaires (PAQs) remains a challenge. The aim of this paper is to 
      provide an updated systematic review of the reliability and validity 
      characteristics of existing and more recently developed PAQs and to 
      quantitatively compare the performance between existing and newly developed 
      PAQs.A literature search of electronic databases was performed for studies 
      assessing reliability and validity data of PAQs using an objective criterion 
      measurement of PA between January 1997 and December 2011. Articles meeting the 
      inclusion criteria were screened and data were extracted to provide a systematic 
      overview of measurement properties. Due to differences in reported outcomes and 
      criterion methods a quantitative meta-analysis was not possible.In total, 31 
      studies testing 34 newly developed PAQs, and 65 studies examining 96 existing 
      PAQs were included. Very few PAQs showed good results on both reliability and 
      validity. Median reliability correlation coefficients were 0.62-0.71 for 
      existing, and 0.74-0.76 for new PAQs. Median validity coefficients ranged from 
      0.30-0.39 for existing, and from 0.25-0.41 for new PAQs.Although the majority of 
      PAQs appear to have acceptable reliability, the validity is moderate at best. 
      Newly developed PAQs do not appear to perform substantially better than existing 
      PAQs in terms of reliability and validity. Future PAQ studies should include 
      measures of absolute validity and the error structure of the instrument.
