Weight Loss Trajectories in Bariatric Surgery Patients and Psychopathological Correlates

Abstract

This study aimed to explore the empirical trajectories of body mass index (BMI) 1 year following bariatric surgery (BS) and to identify the risk factors for each trajectory. The study included 115 patients with severe obesity who underwent BS. Assessment included metabolic variables, psychopathological and personality measures. Growth mixture modelling identified four separated trajectories for the percentage of total weight loss course shape (namely, T1 'good-fast', T2 'good', T3 'low' and T4 'low-slow'). After adjusting for BS subtype and metabolic baseline state, T1 and T2 registered less eating and general psychopathology. T1 was characterized by the lowest scores in novelty seeking and self-transcendence, whereas T4 was defined by the highest scores in novelty seeking and the lowest scores in persistence. Our findings suggest that psychological state prior to BS is predictive of BMI trajectories during the 12 months following BS. These results could be useful in developing more efficient interventions for these patients. Copyright © 2017 John Wiley & Sons, Ltd and Eating Disorders Association.

Psychological predictors of poor weight loss following LSG: relevance of general psychopathology and impulsivity

“…Similarly, in a previous study, higher levels of psychopathology have been related with lower and slower trajectory of weight loss in BS patients [8]. By contrast, in the present study, nor anxiety or depression levels significantly predicted %EWL, although patients achieving successful weight loss were characterized by lower mean scores of anxiety and depressive symptoms.…”

“…Psychiatric symptomatology has been reported in patients with morbid obesity candidates for BS [5] even though there is currently no consensus over the possible effects of psychopathology on post-surgery outcomes. A negative relationship between preoperative psychiatric symptoms, especially depressive and anxiety disorders, and post-surgery weight loss has been suggested [6][7][8][9][10]. However, not all studies confirm preoperative anxiety or depression as having a negative effect on post-surgery outcomes [11][12][13][14].…”

Food addiction and preoperative weight loss achievement in patients seeking bariatric surgery

“…In spite of the positive benefits of preoperative WL achievement, there is not sufficient evidence in the literature to make it compulsory (Kim, 2017;Krimpuri et al, 2018). Although several studies have analysed preoperative predictors of WL after BS, detecting personality traits, cognitive function, mental health, and binge eating as negative factors (Agüera et al, 2015;García-Ruiz-de-Gordejuela et al, 2017;Wimmelmann, Dela, & Mortensen, 2014), only few studies have explored predictors of poor WL achievement prior to BS. Predictors for poor WL prior to BS include being female and non-Caucasian (Hutcheon, Byham-Gray, Marcus, Scott, & Miller, 2017), a high snacking frequency (Bergh, Lundin Kvalem, Risstad, & Sniehotta, 2016), the presence of depressive symptomatology (Nicolau et al, 2017), and having a number of comorbidities (Bergh, Kvalem, Risstad, Cameron, & Sniehotta, 2015).…”

Depressive and Eating Disorders in Patients Post-Bariatric Surgery With Weight Regain: A Descriptive Observational Study

“…Self-reported depression was found mostly in female (p=0.041) and young patients (p=0.042) 6 , supporting the results of King (2019). Depression’s impact on surgical outcomes is not only limited to the statistical results but also it impairs cooperativeness 11 and impedes motivation, both of which interfere with overall adherence to protocols, diet 4 , physical activity 25 , behavioral change, and long-term follow-up adherence 8 . All of these are considered critical protectors for WR, long-term surgical success, and quality of life 9 , 31 , 32 .…”
