Comparison of Two Generations of ActiGraph Accelerometers: The CARDIA Study

This study aimed to examine the comparability of the ActiGraph 7164 and wGT3X-BT wear time, count-based estimates, and average time per day in physical activity of different intensities. Methods We studied 87 Coronary Artery Risk Development in Young Adults (CARDIA) participants 48–60 yr of age who simultaneously wore the 7164 and wGT3X-BT accelerometers at the waist in 2015–2016, with wear time of ≥4 of 7 d, ≥10 h·d−1 for both monitors. Freedson cutpoints (counts per minute) were used to define sedentary (
