Changes in Body Adiposity, Dietary Intake, Physical Activity and Quality of Life of Obese Individuals Submitted to Intragastric Balloon Therapy for 6 Months.

Abstract

Obesity is an important risk factor for several chronic diseases and also is associated with worse quality of life. Intragastric balloon (IGB) is an effective method for weight loss. Although changes in lifestyle are critical to weight loss during and after IGB therapy, only a few studies evaluated dietary intake and none evaluated changes in physical activity with a validated questionnaire during the treatment. The aim of this study was to evaluate changes in total and central body adiposity, dietary intake, physical activity, and quality of life of patients with obesity submitted to IGB treatment for 6months. Prospective observational study involving 42 patients with obesity using IGB for 6months. The patients were evaluated, on the day of insertion and withdrawal or adjustment of IGB for total and central body adiposity (anthropometry and bioelectrical impedance), dietary intake, physical activity (Baecke questionnaire), and quality of life (SF-36 questionnaire). There was a significant decrease in total and central body adiposity. The mean % total weight loss and % excess weight loss were 15.88 ± 1.42 and 56.04 ± 4.90, respectively and waist circumference decreased 13.33 ± 1.39cm. There was a reduction in energy intake, an increase in physical activity, and an improvement of quality of life during IGB treatment. The present study suggests that IGB treatment during 6months in individuals with obesity is effective for decreasing total and central body adiposity being associated with reduction in energy intake, increase in physical activity, and improvement in quality of life.
