Notes: Σ-CISS = CISS test total value; Σ-MET = total metabolic rate; Σ-Screen = total minutes spend using electronic devices; TV = total minutes of TV use; PC = total minutes of PC and Tablet use; Phone = total minutes of Phone use; E-state = subjective rate of emotional state; Δ-Σ-MET = Increment of the total metabolic rate; Δ-Screen = Increment of screen minutes; Δ-TV = Increment of television minutes; Δ-PC = Increment of total minutes of PC use; Δ-Phone = Increment of total minutes of Phone use; Δ-CISS = Increment of the CISS test total value. * p < 0.05; ** p < 0.01; *** p < 0.001.
