Use of combined method, accelerometer and international physical activity questionnaire, to determinate occurence of physical inactivity in adults
- Published on 2017
Aim: Evaluate and compare the proportion of Physical inactivity (PI) and associated factors by IPAQ questionnaire, triaxial accelerometry and the combination of both. Adults aged 18 years were enrolled (n = 250).
Methods: We considered PI as < 600 MET-min/wk in the IPAQ total score, < 150 min/wk of moderate-to-vigorous physical activity in 7 days accelerometry, and the combination of both criteria. Clinical assessment, spirometry, cardiopulmonary exercise test, bioelectrical impedance, isokinetic dynamometry, postural balance, and six-minute walk test were also performed. For participants practicing aquatic, martial arts or cycling, only the IPAQ criterion was considered.
Results: Proportions of PI were significantly different among methods (IPAQ, 10%; accelerometry, 20%; combination, 25%). After multivariate logistic regressions, PI was determined by age, sex, educational level, risk factors for cardiovascular disease, lean body mass, cardiorespiratory fitness, and postural balance.
Conclusions: Thus, the combined method for determining PI and associated factors in adults showed great validity, indicating that questionnaires and accelerometers are complementary and should be utilized in combination in epidemiological studies.
