TI  - Validation of the Arizona Activity Frequency Questionnaire using doubly labeled 
      water.
PG  - 1959-67
AB  - PURPOSE: Physical activity questionnaires (PAQs) are considered the most 
      cost-efficient method to estimate total energy expenditure (TEE) in 
      epidemiological studies. However, relatively few PAQs have been validated using 
      doubly labeled water (DLW) in women or in samples with diverse ethnic 
      backgrounds. This study was conducted to validate the Arizona Activity Frequency 
      Questionnaire (AAFQ) for estimation of TEE and physical activity energy 
      expenditure (PAEE) over 1 month using DLW as a reference method. METHODS: 
      Thirty-five relatively sedentary women completed the AAFQ before participating in 
      an 8-d DLW protocol to measure TEE. TEE and PAEE were estimated from the AAFQ by 
      calculating resting metabolic rate (RMR) using the equation of Mifflin et al. 
      (AAFQmif), by measuring RMR using indirect calorimetry (AAFQic), and using MET 
      conversion (AAFQmet). A predictive equation for TEE was generated. RESULTS: The 
      mean +/- SD for TEE and PAEE from DLW were 9847 +/- 2555 kJ x d(-1) and 5578 +/- 
      2084 kJ x d(-1), respectively. Formulas using RMR to calculate the TEE and PAEE 
      from the AAFQ tended to underestimate TEE and PAEE, whereas those that included 
      only weight tended to overestimate TEE and PAEE. On the basis of the Mifflin et 
      al. equation, the AAFQ tends to underestimate PAEE by 13%. This underestimation 
      may be explained by the low lean body mass of the sample population and by 
      effectiveness of the METs/RMR ratio in the obese. The following predictive 
      equation was calculated: TEE (kJ x d(-1)) = (86.0 * average total daily METs) + 
      (2.23 * RMRmif) - 6726. When the predictive equation is used, TEE calculated from 
      the AAFQ is highly correlated with DLW TEE (adjusted r(2) = 0.70, P < 0.001). 
      CONCLUSION: The AAFQ is an effective tool for the prediction of TEE and PAEE in 
      epidemiological studies.
