This article compares the accuracy of measures of physical activity and associated obesity (as defined by body mass index) derived from questionnaire results vs. accelerometer-measured results. The authors found "approximately twofold stronger associations between physical activity and adiposity with objectively measured than with self-reported physical activity emphasise the need to incorporate objective measures in future studies."
