  1. A = Inactivity maintainers, B = Activity maintainers, C = Decreasers from moderate PA, D = Decreasers from high PA, E = Increasers, MVPA = moderate-to-vigorous physical activity, PA = physical activity
  2. a p-values have been calculated comparing the frequency of the individual response category to each of the corresponding response categories for the other PA patterns (e.g. dropout vs. no dropout (= never+maintenance+adopt))
  3. b Significance over time p < 0.001. At age 15: 1 h 22 min = 9.7% of device wear-time; at age 19: 1 h 5 min = 7.9% of device wear-time
  4. Note: p-values have been assessed using the Chi-square test or Fisher exact test (in cases of sparse data) for categorical variables. The Kruskal-Wallis test was used in analysing differences in mean values between PA patterns cross-sectionally (post hoc Dunn’s test adjusted by the Bonferroni correction for multiple tests); the McNemar test and the Wilcoxon Signed Rank test were used to analyse differences over time
