Objective To validate total energy expenditure (TEE) and activity energy expenditure (AEE) from the portable SenseWear armband (SWA) Pro 2 (TEE SWA and AEE SWA ; InnerView software versions SWA 5.1 and SWA 6.1) against TEE from doubly labeled water (DLW) and AEE from DLW and indirect calorimetry (TEE DLW and AEE DLW ) in overweight/obese lactating women at 10 weeks postpartum. Design and Methods TEE was measured simultaneously with DLW (14 days) and SWA (first 7 days). Lactating women ( n = 62), non‐smoking, with a BMI > 25 kg/m 2 and wearing time SWA ≥ 90% were included. Results Mean TEE SWA5.1 was overestimated with 85 kcal/day compared to TEE DLW ( P = 0.040), while mean TEE SWA6.1 was underestimated with 241 kcal/day compared to TEE DLW ( P < 0.001). Mean AEE SWA5.1 was similar to mean AEE DLW ( P = 0.818), while mean AEE SWA6.1 was underestimated with 581 kcal/day compared to AEE DLW ( P < 0.001). TEE SWA6.1 and AEE SWA6.1 were systematically underestimated at higher levels of energy expenditure and BMI while only AEE SWA5.1 was systematically overestimated at higher levels of energy expenditure. Conclusions TEE SWA5.1 and AEE SWA5.1 were fairly estimated on a group level while TEE SWA6.1 and AEE SWA6.1 were significantly and systematically underestimated. Both SWA software versions showed large individual variation in agreement with TEE DLW and AEE DLW , limiting the validity on individual level.
