Abstract

Background: Various methods are used by epidemiologists to estimate the energy cost of physical activity; these include physical activity records and recalls. However, there is limited validation of these methods against the doubly labeled water technique for determining energy expenditure (EE). Objective: We compared EE as estimated by indirect methods (physical activity records and recall questionnaires) used in epidemiologic studies with EE obtained from doubly labeled water (EEDLW) in free-living men. Design: We determined EEDLW, energy intake at weight maintenance, and EE from 7-d physical activity records (EERecord) and a 7-d physical activity recall questionnaire (EERecall) in 24 men aged 41 ± 2.0 y (̄ ± SEM) with a body mass index (in kg/m2) of 25.1 ± 0.5. Results: There was excellent agreement between EEDLW (13.27 ± 0.35 MJ/d) and energy intake (13.19 ± 0.36 MJ/d), with a difference of 0.5 ± 1.0% (̄ ± SE). The indirect measures of physical activity and EE were 14.17 ± 0.37 MJ/d for EERecord (difference from EEDLW: 7.9 ± 3.2%) and 17.40 ± 1.45 MJ/d for EERecall (difference from EEDLW: 30.6 ± 9.9%). Conclusions: Seven-day physical activity records provide an acceptable estimate of EE in free-living adults compared with EEDLW, but 7-d physical activity recalls have limited application to estimate daily EE. For optimal validity, the 7-d physical activity records require good subject compliance and the provision of careful instructions for their use.
