Uma investigação sobre o comportamento alimentar de indivíduos submetidos à cirurgia bariátrica: uma análise de possíveis condições que determinam e alteram a chamada compulsão alimentar

Abstract

The objective of this work was to investigate the eating behavior of three women who underwent bariatric surgery and propose an intervention for the control of food restriction and the intermittent access to palatable foods as a strategy to change an eating pattern said to be compulsive. Participated in this research three women who agreed to record their daily food ingestion, through an electronic self-monitoring and photo taking during four phases. The first, Baseline, was performed to assess the initial dietary pattern. In Phase 2, the participants were given tokens to exchange for gift cards, in case the electronic record was corresponding to the photo, to ensure the reliability of the record. In Phase 3.1, besides the reinforcement for correspondence, the participants were instructed to eat every three hours and in case of following this guidance, they would also receive the tokens. In Phase 3.2, the instruction and reinforcement were designed for the preparation and intake of a palatable portion of food of up to 150 kcal. During Phase 4, the suspension of the intervention occurred, and only the selfmonitoring and the photo were kept. Among the 3 participants, one (P3) interrupted her participation before the start of Phase 2. The results showed that for P1 and P2, binge eating during Baseline was classified by the quality and quantity of food ingested and after the intervention only the eating behavior before a certain quality of food (sugars and fats) seemed to have been evocative for the binge reporting. The data also showed the change of eating habits of P1 and P2, once the intervals between meals decreased and both began to ingest palatable foods in a more continuous and limited way. This change coincides with the decrease in the report of episodes said to be compulsive, indicating that the variables that the study aimed to alter seem, in fact, to be related to the improper eating behavior of the participants
