AB - Background: Accurate measurement of physical activity is a pre-requisite for monitoring population health and for evaluating effective interventions. The International Physical Activity Questionnaire (IPAQ) is used as a comparable and standardised self-report measure of habitual physical activity of populations from different countries and socio-cultural contexts. The IPAQ has been modified to produce a New Zealand physical activity questionnaire (NZPAQ). The aim of this study was to validate the IPAQ and NZPAQ against doubly labelled water (DLW). Method: Total energy expenditure (TEE) was measured over a 15-day period using DLW. Activity-related energy expenditure (AEE) was estimated by subtracting the energy expenditure from resting metabolic rate and thermic effect of feeding from TEE. The IPAQ (long form) and NZPAQ (short form) were completed at the end of each 7-day period. Activity-related energy expenditure (IPAQ and AEE NZPAQ ) was calculated from each questionnaire and compared to DLW . AEE AEE Results: Thirty six adults aged 18 to 56 years (56% female) completed all measurements. Compared to DLW , IPAQ and NZPAQ on average underestimated energy expenditure AEE AEE AEE by 27% and 59%, respectively. There was good agreement between DLW and both IPAQ and AEE AEE NZPAQ at lower levels of
