The Role of Stigma in Weight Loss Maintenance Among U.S. Adults
Challenges of maintaining long-term weight loss are well-established and present significant obstacles in obesity prevention and treatment. A neglected but potentially important barrier to weight-loss maintenance is weight stigmatization.
We examined the role of weight stigma—experienced and internalized—as a contributor to weight-loss maintenance and weight regain in adults.
A diverse, national sample of 2702 American adults completed an online battery of questionnaires assessing demographics, weight-loss history, subjective weight category, experienced and internalized weight stigma, weight-monitoring behaviors, physical activity, perceived stress, and physical health. Analyses focused exclusively on participants who indicated that their body weight a year ago was at least 10% less than their highest weight ever (excluding pregnancy), the weight loss was intentional, and that attempts to lose or maintain weight occurred during the past year (n = 549). Participants were further classified as weight regainers (n = 235) or weight-loss maintainers (n = 314) based on subsequent weight loss/gain. Data were collected in 2015 and analyzed in 2016.
Hierarchical logistic regression models showed that internalized weight stigma and subjective weight category made significant individual contributions to prediction of weight-loss maintenance, even after accounting for demographics, perceived stress, experienced stigma, physical health, and weight-loss behaviors. For every one-unit increase in internalized weight stigma, the odds of maintaining weight loss decreased by 28% (95% CI: 14–40%, p < .001).
Findings provide initial evidence that overlooked psychosocial factors, like weight stigma, may hinder weight-loss maintenance. Implications for addressing stigma in obesity-focused clinical interventions are highlighted.
