- Very low-calorie diet in candidates for bariatric surgery: change in body composition during rapid weight loss(2019) SERAFIM, Marcela Pires; SANTO, Marco Aurelio; GADDUCCI, Alexandre Vieira; SCABIM, Veruska Magalhaes; CECCONELLO, Ivan; CLEVA, Roberto deOBJECTIVE: To analyze the changes in the body composition of morbidly obese patients induced by a very low-calorie diet. METHODS: We evaluated 120 patients selected from a university hospital. Body composition was assessed before and after the diet provided during hospitalization, and changes in weight, body mass index, and neck, waist and hip circumferences were analyzed. Bioimpedance was used to obtain body fat and fat-free mass values. The data were categorized by gender, age, body mass index and diabetes diagnosis. RESULTS: The patients consumed the diet for 8 days. They presented a 5% weight loss (without significant difference among groups), which represented an 85% reduction in body fat. All changes in body circumference were statistically significant. There was greater weight loss and a greater reduction of body fat in men, but the elderly showed a significantly higher percentage of weight loss and greater reductions in body fat and fat-free mass. Greater reductions in body fat and fat-free mass were also observed in superobese patients. The changes in the diabetic participants did not differ significantly from those of the non-diabetic participants. CONCLUSIONS: The use of a VLCD before bariatric surgery led to a loss of weight at the expense of body fat over a short period, with no significant differences in the alteration of body composition according to gender, age, body mass index and diabetes status.
- Adesão ao seguimento nutricional ambulatorial pós-cirurgia bariátrica e fatores associados(2012) SCABIM, Veruska Magalhaes; ELUF-NETO, Jose; TESS, Beatriz HelenaObjective This study estimated the prevalence of adherence to outpatient postoperative nutritional follow-up after bariatric surgery and analyzed the association between adherence and selected factors. Methods A total of 241 records of female and male adults who underwent Roux-en-Y gastric bypass between 2006 and 2008 were reviewed for this retrospective cohort study. The data included the preoperative and postoperative periods. Individuals were considered compliant when they attended four or more nutritional appointments in the first 12 months after surgery. Prevalence ratios were calculated for estimating the association between adherence to postoperative nutritional follow-up and factors such as age, gender, marital status, education level, employment status, distance between home and hospital, weight loss strategies used during the preoperative period, body mass index immediately before surgery, presence of comorbidities and duration of hospital stay after surgery, and the Poisson multiple regression was used for adjusted analysis. Results Adherence prevalence was 56.0% (CI95% 49.7-62.3). Women composed 80.9% of the population; the mean age of the sample was 44.4 years (SD=11.6) and mean preoperative body mass index was 47.2kg/m(2) (SD=6.2). Among the study factors, only duration of postoperative hospital stay was significantly associated with adherence after adjustment for age and gender (PR=1.46 CI95% 1.15-1.86). Conclusion The adherence prevalence of this population was similar to those of foreign studies, but below the minimum prevalence of 75% considered reference. The greater adherence of individuals with longer postoperative hospital stays may have stemmed from their prolonged interaction with the multidisciplinary team, which may have increased their awareness of disease severity and need of long-term health care.
