Objective vs. self-reported physical activity and sedentary time: effects of measurement method on relationships with risk biomarkers

Imprecise measurement of physical activity variables might attenuate estimates of the beneficial effects of activity on health-related outcomes. We aimed to compare the cardiometabolic risk factor dose-response relationships for physical activity and sedentary behaviour between accelerometer- and qu...
