Predictive Factors of Regain in Bariatric Patients Without Outpatients Care Regular.

Study Overview
=================
Brief Summary
-----------------
The bariatric surgery is recommended for treatment of patients with severe obesity, resulting in greater weight loss and improvement of cardiovascular and metabolic comorbidities. However, weight regain is observed in patients after surgery, leading to health adverse outcomes. The purpose of this study is to identify the rate of weight regain and predictive factors of regain in bariatric patients without outpatients care regular.

Detailed Description
-----------------
Post-bariatric patients without care by health professional will be recruited. Patients will be divided, initially, in two groups by time after surgical procedure, as follows: Group 1≤ (G1≤) - patients that performed bariatric surgery for ≤ 1 year and Group 1> (G1>) - patients that performed bariatric surgery for > 1 year. Patients will be seen in a medical set for the first time at the Policlínica Piquet Carneiro (PPC) for outpatients care, which will consist of anamnesis and physical examination, obtaining demographic, socioeconomic data, medications and clinical history. The TxR will be calculated by [TxR = (current weight - minimum weight reported) x 100 / (weight preoperatively reported - minimum weight related)] and information on predictive variables for weight regain will be obtained by Alcohol Use Disorders Identification Test (AUDIT), Beck Depression Inventory (BDI), International Physical Activity Questionnaire (IPAQ), ActiGraph GT3X + accelerometer, 36-Item Short-Form Health Survey (SF-36), Eating Disorder Examination-Questionnaire (EDE-Q) and Repetitive eating questionnaire (REP(EAT) Q). The inclusion period of new patients in the PPC Obesity Clinic will be one year.
