OBJECTIVE: To develop and validate a short questionnaire to
                estimate physical activity (PA) practice and sedentary behavior
                for the adult population. METHODS: The short questionnaire was
                developed using data from a cross-sectional population-based
                survey (n = 6352) that included the Minnesota leisure-time PA
                questionnaire. Activities that explained a significant
                proportion of the variability of population PA practice were
                identified. Validation of the short questionnaire included a
                cross-sectional component to assess validity with respect to the
                data collected by accelerometers and a longitudinal component to
                assess reliability and sensitivity to detect changes (n = 114,
                aged 35 to 74 years). RESULTS: Six types of activities that
                accounted for 87% of population variability in PA estimated with
                the Minnesota questionnaire were selected. The short
                questionnaire estimates energy expenditure in total PA and by
                intensity (light, moderate, vigorous), and includes 2 questions
                about sedentary behavior and a question about occupational PA.
                The short questionnaire showed high reliability, with intraclass
                correlation coefficients ranging between 0.79 to 0.95. The
                Spearman correlation coefficients between estimated energy
                expenditure obtained with the questionnaire and the number of
                steps detected by the accelerometer were as follows: 0.36 for
                total PA, 0.40 for moderate intensity, and 0.26 for vigorous
                intensity. The questionnaire was sensitive to detect changes in
                moderate and vigorous PA (correlation coefficients ranging from
                0.26 to 0.34). CONCLUSION: The REGICOR short questionnaire is
                reliable, valid, and sensitive to detect changes in moderate and
                vigorous PA. This questionnaire could be used in daily clinical
                practice and epidemiological studies.
