Attitudes and Behaviors towards Food and Weight in Late Pregnancy: A Comparative Approach between Individuals with and without Previous Bariatric Surgery

The aims of this study were to compare, between pregnant individuals with and without bariatric surgery: (1) eating behaviors, (2) intuitive eating components and, (3) attitudes towards weight gain. This retrospective study included data collected in healthy pregnant individuals with and without previous bariatric surgery who were recruited at the Centre Hospitalier Universitaire (CHU) de Qu & eacute;bec-Universit & eacute; Laval. Pregnant individuals who underwent bariatric surgery (biliopancreatic bypass with duodenal switch [n = 14] or sleeve gastrectomy [n = 5]) were individually matched, for age (+/- 0.4 years) and body mass index (BMI) (+/- 0.3 kg/m(2)), with pregnant individuals who have not received bariatric surgery. In the second trimester, participants completed the Three Factor Eating Questionnaire (TFEQ) and the Intuitive Eating Scale 2 (IES-2). In the third trimester, participants completed the French version of the Pregnancy Weight Gain Attitude Scale assessing attitudes towards weight gain. Pregnant individuals who have had bariatric surgery had a higher score for flexible restraint and a lower score for situational susceptibility to disinhibition compared to individuals who have not had undergone bariatric surgery (2.89 +/- 1.15 vs. 1.95 +/- 1.31; p = 0.04 and 1.11 +/- 1.29 vs. 2.79 +/- 1.44, respectively; p < 0.001). Regarding intuitive eating, pregnant individuals who experienced bariatric surgery had a higher score for reliance on internal hunger and satiety cues and a lower one for unconditional permission to eat compared with those who had not experienced bariatric surgery (3.99 +/- 0.81 vs. 3.30 +/- 1.03; p = 0.02 and 3.28 +/- 0.54 vs. 3.61 +/- 0.68, respectively; p = 0.03). No difference in attitudes towards weight gain was observed between groups. Overall, pregnant individuals who had undergone bariatric surgery had different eating behaviors and intuitive eating components compared to pregnant individuals without bariatric surgery. These results need to be confirmed in further studies with larger sample sizes.
