Abstract
Background: Weight discrimination is associated with adverse outcomes, including eating disorder (ED) symptoms, but few longitudinal studies have investigated this relationship in early adolescence. We examined the prospective association of weight discrimination with ED symptoms one year later in early adolescents, and the extent to which this association was moderated by body mass index (BMI) percentile and sex.
Methods: We analyzed prospective data from Year 2 (2018-2020) and Year 3 (2019-2021) of the Adolescent Brain Cognitive Development (ABCD) Study (N = 9,079). To estimate the associations between self-reported experiences of weight discrimination in Year 2 and ED symptoms in Year 3, we conducted multiple logistic and ordinal logistic regression analyses, controlling for potential covariates, including ED symptoms in Year 2. Weight discrimination was measured using the Perceived Discrimination Scale. Presence of various ED symptoms was assessed via parent report using the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5). Participant BMI percentile and sex were also investigated as potential moderators.
Results: Weight discrimination was prospectively associated with higher odds of worry about weight gain (adjusted odds ratio [aOR] 2.12, 95% confidence interval [CI] 1.08-4.14, p = 0.028), self-worth tied to weight (aOR 3.75, 95% CI 2.54-5.55, p < 0.001), inappropriate compensatory behaviors to prevent weight gain (aOR 2.75, 95% CI 2.02-3.74, p < 0.001), binge eating symptoms (aOR 1.72, 95% CI 1.10-2.68, p = 0.018), and distress about binge eating (aOR 2.26, 95% CI 1.33-3.85, p = 0.002) one year later. Weight discrimination was also associated with higher odds of a greater number of overall ED symptoms one year later (aOR 2.21, 95% CI 1.61-3.03, p < 0.001). A significant interaction by BMI percentile was also found: in adolescents with BMI of 5th to < 85th percentile, weight discrimination was more strongly and prospectively associated with higher odds of binge eating symptoms (aOR 3.32, 95% CI 1.27-8.68, p = 0.015) and binge eating distress (aOR 5.11, 95% CI 2.10-12.44, p < 0.001).
Conclusions: Results support a prospective relationship between perceived weight discrimination and ED symptoms in early adolescents, and the differential associations based on BMI percentile highlight the need for interventions that address weight stigma across the weight spectrum.
期刊介绍:
Journal of Eating Disorders is the first open access, peer-reviewed journal publishing leading research in the science and clinical practice of eating disorders. It disseminates research that provides answers to the important issues and key challenges in the field of eating disorders and to facilitate translation of evidence into practice.
The journal publishes research on all aspects of eating disorders namely their epidemiology, nature, determinants, neurobiology, prevention, treatment and outcomes. The scope includes, but is not limited to anorexia nervosa, bulimia nervosa, binge eating disorder and other eating disorders. Related areas such as important co-morbidities, obesity, body image, appetite, food and eating are also included. Articles about research methodology and assessment are welcomed where they advance the field of eating disorders.
