N2 - Objectives: The purpose of this study was to develop and assess the reliability and validity of a single page, physical activity questionnaire, for estimation of energy expenditure in Greek adults. Equipment and methods: The Athens Physical Activity Questionnaire (APAQ) was designed to assess energy expenditure of the previous 7 days, in Greek language. Sixty subjects (40 women, age: 20.9 ± 1.7 years, BMI: 21.4 ± 2.7 kg/m2; 20 men, age: 22.4 ± 3.1 years, BMI: 23.5 ± 3.1 kg/m2) completed the APAQ on two separate occasions, 7 to 14 days apart, to assess internal consistency and test-retest reliability, using Cronbach alpha and intraclass correlation coefficients (ICC), respectively. Additionally, 79 more subjects (42 women, age: 26.6 ± 6.1 years, BMI: 20.6 ± 1.8 kg/m2; 37 men, age: 30.0 ± 6.1 years, BMI: 25.1 ± 2.2 kg/m2) wore a triaxial accelerometer for 7 consecutive days, and then completed the APAQ to assess validity, using correlation and Bland-Altman analysis. Results: ICC were 0.95, 0.78, 0.58 and 0.85 (P < 0.001) for total, occupational, home and recreational EE, respectively. Total energy expenditure derived from APAQ was significantly correlated (r = 0.839, P < 0.001) to accelerometer measures. Bland-Altman analysis showed a good agreement between the two methods with most of the differences within the 95% limits of agreement. It was concluded that APAQ is a reliable and valid tool for estimation of individual energy expenditure in Greek adults, suitable for clinical and epidemiological studies.
