Correlates of agreement between accelerometry and self-reported physical activity

Popis výsledku v původním jazyce

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
