The aim of this study was to assess the compliance of Axivity AX3 accelerometers taped directly to the skin of 9-13-year-old children.METHODS: Children in 46 school classes (53.4{\%} girls, age 11.0±1.0 years, BMI 17.7±2.8 kg*m) across Denmark wore two Axivity AX3 accelerometers, one taped on the thigh (n=903) and one on the lower back (n= 856), for up to ten consecutive days. Participants were instructed not to reattach an accelerometer should it fall off. Simple and multiple linear regression were used to determine associations between accelerometer wear time and age, sex, BMI percentiles, and PA level.RESULTS: Over 65{\%} had >7 days of uninterrupted, 24h wear time for the thigh location, and 59.5{\%} for the lower back location. From multiple linear regressions, PA levels showed the strongest association with lower wear time (thigh: β=-.231, R=.066; lower back: β=-.454, R=.126). In addition, being a boy, being older (only for lower back), and having higher BMI percentile were associated with lower wear time.CONCLUSION: Using skin-taped Axivity accelerometers, we obtained seven days of uninterrupted accelerometer data with 24h wear time per day with a compliance rate of more than 65{\%}.
