OBJECTIVES: The objectives of this study were to investigate the effect of adherence to postoperative recommendations on anthropometric measurements and body composition and assess the percentage of total weight loss (%TWL) and excess weight loss (%EWL) 3 months postoperative.
SETTINGS: Fifty-two participants who underwent a Roux-en-Y gastric bypass or sleeve gastrectomy in the University of Jordan Hospital were included.
METHODS: Participants have filled out a preoperative questionnaire. Anthropometric measurements were obtained preoperative and 3 months postoperative using a Body Impedance Analyzer (Inbody 270). The adherence to postoperative recommendations was assessed by the Bariatric Surgery Self-management Questionnaire 3 months postoperative and classified to 3 adherence levels.
RESULTS: Most anthropometric measurements decreased 3 months postoperative in the 3 adherence groups (P ≤ .05). No significant differences were observed between groups in anthropometric measurements and body composition, except for minerals and visceral fat levels. The mineral loss has decreased in both the high and intermediate adherence groups (-.09 ± .22 kg, and -.09 ± .18 kg, respectively). Also, the high adherence group showed less loss in protein amount postoperatively (P = .06). Visceral fat level decreased in the high adherence group (P ≤ .05).
CONCLUSIONS: Adherence to postoperative behavioral and nutritional recommendations was associated with less protein and mineral loss and enhanced visceral fat reduction postoperatively.
