Criterion validity of the sedentary behavior question from the global physical activity questionnaire in older adults
Background: The aim of this study was to assess the validity of the single question to determine sedentary behavior (SB) by using the Global Physical Activity Questionnaire (GPAQ) in older adults.

| Sumario: | Background: The aim of this study was to assess the validity of the single question to determine sedentary behavior (SB) by using the Global Physical Activity Questionnaire (GPAQ) in older adults. Methods: The sample included 163 participants (96 women), aged 65 to 92 years. Self-reported SB was obtained from the GPAQ. Objectively measured SB was assessed using the Intelligent Device for Energy Expenditure and Activity (IDEEA). Participants wore the IDEEA continuously during two consecutive days while following their daily routine. The relative validity was assessed using the Sperman rank correlation coefficient (rho) and the agreement was examined using mean bias and 95% limit of agreement (LoA) with the IDEEA as reference. Results: The results showed small correlations between the SB from the GPAQ and the objective measures (rho = 0.291, p<0.001) and ranged from rho=0.217 to rho=0.491 depending on the potential moderator. Likewise, the GPAQ underestimates the SB approximately 2 h/day in older adults (LoA = -7.3 to 3.4 h/day). Conclusion: The GPAQ may not be the most suitable questionnaire for measuring SB in this population and should be used with caution, because those studies that use this questionnaire in older adults may have an inaccurate measurement of SB levels |
