Use of the activPAL triaxial accelerometer to estimate total energy expenditure in low-income women: differences between body mass index classifications.

Objective: This study aimed to assess the agreement between the total energy expenditure (TEE) estimated by the activPAL triaxial accelerometers (ACC) and the TEE measured by the doubly labeled water method (DLW), as well as to assess if these values differ between the classifications of body mass index (BMI).

Materials And Methods: This is a cross-sectional study. Low-income adult women (19-45y) with BMI ≥ 18.
