II. O bjectives To know the reasons for the success or failure of overweight loss (%PEP) in patients undergoing bariatric surgery, and its relationship (or association) with the elapsed time of surgery, quality of food consumption and physical activity. III. M ethod This research was authorized by the Research Ethics Committee (CEP) of the Santa Casa de Misericórdia Brotherhood of São Paulo under n. of CAAE 23694219.4.0000.5479. Patients were considered to be able to participate in the research after reading and signing the free and informed consent form. This is an observational cross- sectional study. Bariatric patients with surgical time between 2 and 7 years, older than 18 years, without comorbidities treated at the Bariatric Nutrition Specialty Outpatient Clinic of the Hospital da Irmandade da Santa Casa de Misericórdia of São Paulo (ISCMSP) were evaluated. As exclusion criteria: Pregnant women, nursing mothers, drug addicts, alcoholics, smokers, cancer patients and those using drugs for weight loss. To define the percentage difference in weight lost in relation to excess weight (%PEP), the weight recorded on the day of surgery was used as a basis, the ideal weight for the Body Mass Index (BMI) value as proposed by the FAO and for for patients aged 60 years or more, the BMI was used according to the age and minimum weight achieved in the post-surgery period, as described by Novais 11 . The loss of excess weight is considered one of the main parameters to define the success of the surgical procedure, and researchers agree that the criterion for this assessment is the %WBS of at least 50%. Patients were divided into two groups (group I: successful PEP>50% and group II: unsuccessful PEP<50%). To verify thepossible causes of overweight recovery in this group, the food frequency questionnaire (FFQ) adapted from SICHIERI 12 and EVERHART 13 was applied with the classification of higher calorie food groups that could contribute to the recovery of excess weight if consumed with higher frequency and for behavior analysis for the practice of physical activity, a questionnaire was applied according to VIGITEL 14 2018 (Surveillance of Risk Factors and Protection for Chronic Diseases by Telephone Survey). An analysis of the frequency of consumption of selected food groups was performed according to the Fisher test for a significance level of p < 0.05. (Table 1), to analyze the practice of physical activity, the Chi-square test was used. (Table 2) IV. R esults Were evaluated forty-five female patients with surgical times ranging from 2 to7 years were evaluated. Patients were divided into two groups: those considered successful PEP>50%, called G1 (n=31), and those considered unsuccessful with PEP<50%, called G2 (n=14). There was no statistical difference (p=0.815) between the mean ages of G1 (48.3 years±1.19) and G2 (48.5 years ±1.2). In this study group, patients with 2 and 3 years of surgery had 66% success, with 4 years 81% success, with 5 and 6 years 50% success and with 7 years 100% successful.
