Correlates of agreement between accelerometry and self-reported physical activity

Original language description

Understanding factors that influence accurate assessment of physical activity and sedentary behavior is important to measurement development, epidemiologic studies, and interventions. This study examined agreement between self-reported (International Physical Activity Questionnaire) and accelerometry-based estimates of PA and SB across six countries, and identified correlates of between-method agreement. Self- report and objective (accelerometry-based) PA and SB data were collected in 2002-2011 from 3,865 adult participants in eight cities from six countries (Belgium, Czech Republic, Denmark, Spain, UK, and USA). Between-method relative agreement (correlation) and absolute disagreement (mean difference between conceptually- and intensity-matched IPAQ-LF and accelerometry-based PA and SB variables) were estimated. Also, socio-demographic characteristics and PA patterns were examined as correlates of between-method agreement. Observed relative agreement (relationships of IPAQ-LF with accelerometry-based PA and SB variables) was small to moderate (r=0.05-0.37) and was moderated by socio- demographic (age, sex, weight status, education) and behavioral (PA-types) factors. The absolute disagreement was large, with participants self-reporting higher PA intensity and total time in moderate-to-vigorous PA than accelerometry. Also, self-reported sitting time was lower than accelerometry-based sedentary behavior. After adjusting for socio-demographic and behavioral factors, the absolute disagreement between pairs of IPAQ-LF and accelerometry-based PA variables remained significantly different across cities/countries. Present findings suggest systematic cultural and/or linguistic and socio-demographic differences in absolute agreement between the IPAQ-LF and accelerometry-based PA and SB variables. These results have implications for the interpretation of international PA and SB data and correlates/determinants studies. They call for further efforts to improve such measures
