Objective: To validate total energy expenditure (TEE) and activity energy expenditure (AEE) from the portable SenseWear armband (SWA) Pro 2 (TEESWA 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 (TEEDLW 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 TEESWA5.1 was overestimated with 85 kcal/day compared to TEEDLW (P = 0.040), while mean TEESWA6.1 was underestimated with 241 kcal/day compared to TEEDLW (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). TEESWA6.1 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: TEESWA5.1 and AEE(SWA5.1) were fairly estimated on a group level while TEESWA6.1 and AEE(SWA6.1) were significantly and systematically underestimated. Both SWA software versions showed large individual variation in agreement with TEEDLW and AEE(DLW), limiting the validity on individual level.
