Association Between Weight Gain, Psychological, Sociodemographic Factors, and Physical Activity in Bariatric Patients: A Network Perspective
Abstract Background Weight gain affects about 10-20% of patients after bariatric surgery (BS). It’s a phenomenon that’s difficult to understand and to intervene due to its complexity and etiological heterogeneity. In the present study, we investigated, from a network analysis perspective, the associations between weight regain, psychological, sociodemographic factors and physical activity in patients undergoing BS. Methods The sample consisted of 124 patients, of both sexes, aged 39 ± 9.1 years, who had undergone surgical intervention for more than 18 months. After voluntary consent, respondents answered questionnaires and instruments directly on the Google Forms platform. Results The weight gain was negatively associated with the items of depression, anxiety and stress, binge eating and with the dimensions of the personality questionnaire (negative affectivity -0.182; detachment -0.078; antagonism -0.107; disinterest - 0.198 and psychoticism -0.158). Conclusion Characteristics of disinterest and negative affectivity and most of the items on the depression, anxiety and stress scale had a greater expected influence, indicating that these are the most sensitive variables to intervention and who need more attention from health professionals.Level of evidence: Level III, evidence obtained from well-designed case-control analytic studies.
