3.6.2. Child Activity Level
FitBit measures for sedentary and light activity levels appeared to be the most feasible measures in the study population, while fairly and very active levels up to 18 months showed mostly a median of 0. Sedentary levels decreased in all three groups over time, from 1393 (control group), 1375 (investigational group), and 1360 (breastfed group) min at 6 months to 1252 (control group), 1244 (investigational group), and 1244 (breastfed group) min at 24 months. Light activity levels increased across the study period from 42 (control group), 63 (investigational group), and 70 (breastfed group) min at 6 months to 166 (control group), 189 (investigational group), and 176 (breastfed group) min at 24 months. We observed a trend toward being less sedentary and more lightly active in the investigational group compared to the control and breastfed reference groups at 24 months (
