“…The present study is one of few (14)(15)(16) (Table 2) in this study supports the advantage of physical activity records for estimating EE in a population. Although this study was conducted under carefully controlled conditions, the small size of the study population may have been a limiting factor and may explain the lack of significance when EE Record was regressed against EE DLW .…”

“…The error in determining the energy cost of physical activity from physical activity records in the other 12 subjects may be attributed to factors such as misreporting, body weight, degree of overweight, and environment (28). Earlier reports (14,29) found that the MET intensities listed in the Compendium of Physical Activities (7) for overweight individuals may be inaccurate and that the inaccuracies may be different for weight-and non-weight-bearing activities. Estimation of EE from the frequency, duration, and type of activities recorded in the physical activity record may contribute errors, which could explain the observed R 2 of 0.10 between EE DLW and EE Record .…”

“…However, few epidemiologic methods for estimating EE from physical activity records and recalls have been cross-validated simultaneously against the doubly labeled water method under well-controlled conditions (14)(15)(16). In the present study, we sought to provide independent estimates of EE from 7-d physical activity records (EE Record ) and a 7-d physical activity recall (EE Recall ; with use of the Stanford 7-d physical activity questionnaire), measures of energy intake (EI) at weight maintenance, and measures of doubly labeled water (EE DLW ).…”

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 (EE DLW ) in free-living men. Design: We determined EE DLW , energy intake at weight maintenance, and EE from 7-d physical activity records (EE Record ) and a 7-d physical activity recall questionnaire (EE Recall ) in 24 men aged 41 ± 2.0 y (x -± SEM) with a body mass index (in kg/m 2 ) of 25.1 ± 0.5. Results: There was excellent agreement between EE DLW (13.27 ± 0.35 MJ/d) and energy intake (13.19 ± 0.36 MJ/d), with a difference of 0.5 ± 1.0% (x -± SE). The indirect measures of physical activity and EE were 14.17 ± 0.37 MJ/d for EE Record (difference from EE DLW : 7.9 ± 3.2%) and 17.40 ± 1.45 MJ/d for EE Recall (difference from EE DLW : 30.6 ± 9.9%). Conclusions: Seven-day physical activity records provide an acceptable estimate of EE in free-living adults compared with EE DLW , 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.Am J Clin Nutr 2002;75:519-25.

“…The criterion field method for estimating individual EE has been doubly labeled water (DLW) (11, 12, 13). However, the cost and availability of isotopes and the requirement for analysis by isotope ratio mass spectrometer prohibits DLW from being widely used in studies of large populations.…”

IRWIN, MELINDA L., BARBARA E. AINSWORTH, AND JOAN M. CONWAY. Estimation of energy expenditure from physical activity measures: determinants of accuracy. Obes Res. 2001;9:517-525. Objective: To describe the determinants, specifically age, body mass index, percentage of body fat, and physical activity (PA) level, associated with over-and underestimation of energy expenditure (EE) using PA records and the Stanford Seven-Day Physical Activity Recall (7DR) compared with doubly labeled water (DLW). Research Methods and Procedures:We collected PA measures on 24 males eating a controlled diet designed to maintain body weight, and we determined EE from DLW and estimated EE from PA records and 7DR. Results: Absolute differences in the estimation of EE between DLW and PA assessment methods were greater for the 7DR (30.6 Ϯ 9.9%) than PA records (7.9 Ϯ 3.2%). In PA records, overestimation of EE was greater with older age and higher body fatness; EE was overestimated by 16.7% among men 50 years and older compared with only 5.3% among men Ͻ40 years of age. For percentage of body fat, EE was overestimated by 19.7% among men with a percentage of body fat Ն30% compared with only 5.6% among men with a percentage of body fat Ͻ25%. A trend for less overestimation of EE with higher levels of PA (measured by DLW/basal metabolic rate [BMR]) also was observed in the PA records. In the 7DR, the estimates of EE varied widely and no trends were observed by age, percentage of body fat, and PA levels. Discussion: Estimation of EE from the 7DR is considerably more variable than from PA records. Factors related to age and percentage of body fat influenced the accuracy of estimated EE in the PA record. Additional studies are needed to understand factors related to accurate reporting of PA behaviors, which are used to estimate EE in free-living adults.

“…This creates a dilemma: does one use the measured RMR, calculated RMR, or some combination of the two when calculating the energy expended in physical activity? In this regard, several authors (5,8,10,13,18,22) have noted that the MET system underestimates energy expenditure in heavy or obese subjects when measured RMR is used in the calculation. Racette et al (18) went further and proposed a modified way of calculating energy expenditure of obese individuals using measured RMR plus (MET-1) times 4.184 kJIkg j1 Ih j1 .…”
