Min/day spent in sedentary behavior and physical activity among quartiles of age in children of the GENOBOX study, estimated using selected accelerometry protocols. A Min/day spent in sedentary behavior; B min/day spent in light, moderate and vigorous physical activity; C min/day spent in moderate-vigorous physical activity. PA light physical activity; Q1: < 10 year-old; Q2: 10–11.7-year-old; Q3: 11.7–13.7-year-old; Q4: 13.7-year-old; MPA moderate physical activity, MVPA moderate-vigorous physical activity; SB sedentary behavior, VPA vigorous physical activity. *Age quartiles differences (p < 0.05) applying 20 min non-wear-time criteria by a one-way ANOVA. No matching superscript letters (a, b, c, d) indicate significant differences by pairwise applying 20 min non-wear-time. Note: Data presented in the figure had the same behavior that those obtained with the 60-min non-wear-time (results not shown)
