Purpose: Overweight and obesity are increasing among Italian children, particularly due to sedentary lifestyle. The evaluation of daily energy expenditure (EE) is therefore relevant to assess the level of physical activity in subjects at risk. Portable devices could improve the free-living EE monitoring, provided they are properly calibrated and validated. The present study aimed at evaluating a new multisensor wrist monitor (WM) (E3®, Empatica srl, Italy) in EE assessment in obese children and adolescents. Methods: Twenty-eight participants (15 males; age 13 ± 2 years; mean ± SD) were enrolled. Nineteen subjects were obese (body mass index (BMI) >95th percentile for age and sex). Subjects were tested (1) while sitting (SIT), and during (2) walking at comfortable speed (SS) and (3) at faster speed (FS). EE was assessed in each condition by both indirect calorimetry (IC, by oxygen consumption measurement) and multisensor (accelerometry, heart rate, skin galvanic reaction, temperature) methods. Results: EE measured during SIT, SS and FS was 1.48 ± 0.31, 4.25 ± 0.68 and 5.64 ± 0.92 METs with IC and 1.19 ± 0.11, 3.82 ± 0.77 and 5.17 ± 0.81 METs with WM, respectively. A significant difference (P
