Relationships Between Self-Esteem, Interoceptive Awareness, Impulse Regulation, and Binge Eating. Path Analysis in Bariatric Surgery Candidates

Potential pathways to the onset and development of eating disorders in people with overweight and obesity: A scoping review

OBJECTIVE

To describe pathways to eating disorder (ED) development that have been evaluated in people with overweight and obesity.

METHODS

Four databases were searched to identify studies testing ED development models in adolescents (10-19 years) or adults (>19 years) with overweight and obesity. Explanatory variables were thematically grouped into constructs to describe pathways to each ED outcome.

RESULTS

Of 2226 studies screened, 46 (10 adolescent; 36 adult) were included. Study samples were predominantly female, ranging from 22 to 2236 participants and mean age 12.3 to 56.0 years. In total, 207 explanatory variables were grouped into 18 constructs to summarize 107 pathways that were identified. The most common ED outcome was binge eating (n = 24 studies), followed by global ED psychopathology (n = 10 studies). Across pathways to ED development, negative affect was the most proposed construct, followed by preoccupation with weight/shape and weight stigma.

CONCLUSION

Pathways to ED development in people with overweight and obesity are complex and may include more than 18 different explanatory factors of which negative affect, preoccupation with weight/shape, and weight stigma are the most common. More research on adolescents, males, and the spectrum of ED in diverse populations is required for early identification and intervention.

Bodily sensations and bariatric surgery: Links between interoceptive sensibility, intuitive and disordered eating behaviour in obesity and obesity surgery

OBJECTIVE

This study evaluated interoceptive sensibility, intuitive and disordered eating among bariatric candidates, operated individuals and individuals with obesity seeking non-surgical treatment.

METHOD

We recruited 57 individuals with obesity seeking nonsurgical weight-loss (IOB), 84 bariatric candidates (Pre) and 22 individuals post-bariatric surgery (Post) who responded to questionnaires: Multidimensional Assessment of Interoceptive Awareness, Intuitive Eating Scale-2 (IES-2), Dutch Eating Behaviour Questionnaire, Binge Eating Scale, State-Trait Anxiety Inventory, Beck's Depression Inventory.

RESULTS

Overall, the Post group manifested higher scores on 'Body-Listening' (F = 4.95, p = 0.01), 'Emotional Awareness' (F = 8.83, p < 0.001) and 'Trusting' (F = 6.71, p = 0.002) interoceptive dimensions, on the IES-2 total score (F = 5.48, p = 0.007) and 'Reliance on hunger and satiety cues' (F = 31.3, p < 0.001) when age was controlled. The IOB group presented higher scores on emotional (F = 3.23, p = 0.047) and binge eating (F = 5.99, p = 0.004). Among operated individuals, intuitive eating mediated the relationship between interoceptive sensibility dimensions and binge eating: 'Attention regulation' (54%) 'Self-regulation' (75.1%), 'Body listening' (94.09%) and 'Trusting' (84.9%).

CONCLUSIONS

Our results suggest the therapeutic potential of interoceptive sensibility and intuitive eating in obesity management in/beyond the bariatric context.
