Anthropometric parameters
Anthropometric measures were obtained at the baseline (day of IGB insertion) and 6 months later, at the end of the study (day of IGB removal). Height was measured with a stadiometer accurate to ±0.5 cm, and weight was obtained using a calibrated scale accurate to ±0.1 kg after participants, without shoes and wearing light clothing, attempted to empty their bladder. BMI was calculated using the standard equation (kg/m2) and was classified as pre-obesity (25.00-29.99), grade I obesity (30.0-34.9), grade II obesity (35.0-39.9) and grade III obesity (≥40.0) [9].
