The Body Advocacy Movement-Health: a pilot randomized trial of a novel intervention targeting weight stigma among health professional students.

BACKGROUND: Weight stigma among healthcare professionals is associated with negative health impacts on patients, yet there are few effective strategies to combat weight stigma among health professional learners. The Body Advocacy Movement-Health (BAM-Health) is a novel group-based, peer-led stigma reduction intervention for health professional students that targets weight stigma across intrapersonal, interpersonal, and structural levels. The present study (1) assesses short-term impacts of BAM-Health participation on intrapersonal and interpersonal weight bias compared to an informational brochure control condition and (2) explores the feasibility and acceptability of BAM-Health among a sample of health professional students. METHODS: Sixty-seven health professional students participated in BAM-Health (n = 34) or received an informational brochure about weight stigma (n = 33). Participants completed validated self-report surveys assessing internalized weight/ appearance concerns and interpersonal weight stigma prior to their assigned intervention (baseline), immediately following intervention (post-intervention), and four weeks after intervention (follow-up). Baseline to post-intervention and baseline to follow-up effect sizes on each measure were calculated. At post-intervention, participants completed feedback surveys for thematic assessment. RESULTS: BAM-Health participation had a large baseline to post-intervention effect on internalized weight/ appearance concerns that diminished slightly at follow-up (Cohen's d = -0.88; d = -0.62). Receipt of the informational brochure had a small effect on internalized weight/ appearance concerns (d = -0.27); however, these changes were not sustained at follow-up (d = 0.04). BAM-Health participation resulted in reductions in interpersonal obesity stigma and anti-fatness with small effect sizes (d = -0.32; d = -0.31). The effect on obesity stigma was slightly amplified at follow-up (d = -0.43); however, decreases in anti-fatness were not sustained (d = -0.13). The brochure condition failed to demonstrate effects on anti-fatness (d = 0.13, d = 0.14) or obesity stigma (d = -0.12; d = -0.12) at either time point. Between-session attrition rates of 4.5%, favorable quantitative ratings on post-session acceptability surveys, and free responses demonstrating appreciation of the virtual group environment and session activities reflect feasibility and acceptability of BAM-Health. CONCLUSIONS: BAM-Health is a novel peer-led intervention that aims to reduce weight stigma among health professional students. BAM-Health met feasibility benchmarks and received positive feedback from participants, demonstrating acceptability and indicating interest among health professional students in analyzing and reducing weight stigma in their personal lives and careers. The intervention led to promising decreases in internalized and interpersonal weight stigma at post-intervention, some of which were sustained at follow-up. However, lack of effect on internalized weight/ appearance concerns measures may indicate that BAM-Health participants are more likely to reject weight stigma directed toward others following intervention, while maintaining thin ideals for themselves. Further investigation of BAM-Health with a larger sample and continued program development is warranted.

Weight stigma refers to negative attitudes or harmful behaviors directed toward oneself (internalized weight stigma) or others (interpersonal weight stigma) on the basis of body weight. Structural weight stigma refers to policies or norms that harm people who have higher body weights. Weight stigma in healthcare in particular can contribute to negative physical and emotional health outcomes among patients. To examine strategies to mitigate weight stigma in healthcare, health professional students at a large university in the United States ­ including students in medical, nursing, and physical therapy programs ­ participated in the Body Advocacy Movement-Health (BAM-Health), a program created to decrease weight stigma in this population. Participants completed surveys prior to and after BAM-Health that indicated modest reductions in internalized and interpersonal weight stigma four weeks after completion of the intervention, whereas those in the comparison arm did not demonstrate sustained changes in measures of weight stigma. Furthermore, participants indicated that they enjoyed involvement in BAM-Health and found it useful both personally and professionally. Future research with larger, more diverse sample sizes is necessary to determine whether BAM-Health is effective at reducing weight stigma among health professional students and whether it improves quality of care for patients in larger bodies.

Adaptive and Maladaptive Exercise in Eating Disorders.

While exercise is generally associated with positive health outcomes, in the context of eating disorders, exercise has high potential to become maladaptive. Maladaptive exercise is compelled or compulsive in nature for the purposes of weight and shape control or to obtain/avoid other eating disorder-relevant consequences. A transdiagnostic eating disorder feature with moderate-to-high prevalence across restrictive- and bulimic-spectrum eating disorders, maladaptive exercise is often associated with negative mental and physical health sequalae. Several proposed threat- and reward-related biobehavioral mechanisms may initiate or perpetuate maladaptive exercise. While exercise is generally contraindicated during periods of acute medical concern, adaptive forms of exercise are also present among those with eating disorders, and facilitation of adaptive exercise has potential to promote physical and mental health benefits during eating disorder recovery. Detailed assessment and targeted interventions are needed to address the clinical conundrum of how and when to integrate exercise into eating disorder treatment.

A pilot randomized trial of the body advocacy movement: a novel, dissonance-based intervention designed to target fear of weight gain and anti-fat bias in young adults.

The Body Advocacy Movement (BAM) is a novel, cognitive-dissonance-based intervention designed to target fatphobia and anti-fat bias as mechanisms to drive reductions in eating disorder (ED) risk. Previous dissonance-based programs (i.e. the Body Project; BP) have successfully targeted thin-ideal internalization as an intervention mechanism. As burgeoning research indicates that fatphobia and anti-fat bias may play a central role in the maintenance of ED pathology, a focused intervention designed to target these constructs could bolster prevention efforts. The aims of this pilot study include confirming acceptability and feasibility of BAM and developing preliminary estimates of its effects on intervention targets, along with benchmarking these effects against the BP intervention. BAM was found to be accepted by participants and feasible to facilitate in a peer-led model. Preliminary results from 50 participants (BAM: N = 26; BP: N = 24) reveal small-to-moderate pre-to-post intervention effects on fatphobia, anti-fat bias, thin-ideal internalization, and eating pathology, which dissipated at 8-week follow-up. The BAM intervention has the potential to supplement the existing suite of ED prevention programs by specifically targeting anti-fat bias, though additional testing in larger and more diverse samples is necessary to clarify its impact on both hypothesized risk mechanisms and ED outcomes.
