- 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.
- Obese patients lose weight independently of nutritional follow-up after bariatric surgery(2015) TESS, Beatriz Helena; SCABIM, Veruska Magalhães; SANTO, Marco Aurélio; PEREIRA, Júlio César R.Summary Objective: to examine the association between preoperative body weight, adherence to postsurgical nutritional follow-up, length of postoperative period, and weight loss during the first 18 months among adults who have undergone bariatric surgery. Methods: a retrospective cohort study was conducted on 241 consecutive patients who underwent open Roux-en-Y gastric bypass (RYGBP) from January 2006 to December 2008, in a teaching hospital in São Paulo (Brazil). Data were collected through hospital records review and the variables analyzed included sex, age, immediate preoperative weight, adherence to postsurgical nutritional visits and length of postoperative period. Proportional body weight reductions during the 18-month follow-up period were examined using generalized estimating equations. Results: 81% (n=195) of participants were female, with overall mean age of 44.4 ± 11.6 years, mean preoperative weight of 123.1± 21.2 kg and mean preoperative body mass index of 47.2± 6.2 kg/m2. The overall adherence to postoperative follow- up schedule was 51% (95%CI: 44.5-57.5%). Preoperative body weight and adherence were not associated with proportional weight reduction (Wald’s test p > 0.18). Weight loss leveled off at the end of the 18-month follow-up period for both compliant and non-compliant patients (Wald’s test p = 0.00). Conclusions: our study showed that weight loss occurred steadily over the first 18 months after RYGBP, leveling off at around 40% weight reduction. It was associated with neither presurgical weight, nor nutritional follow-up and it may be primarily dependent on the surgical body alterations themselves. This finding may have implications for intervention strategies aimed at motivating patients to comply with early postsurgical and life-long follow-up.
