Revised presentation of obesity may reduce internalized bias


 

FROM CLINICAL OBESITY

Presenting obesity as a chronic medical condition, rather than as a failure to eat less and move more, may improve self-esteem among patients with obesity and enhance their relationships with their doctors, a new study suggests.

In an online study, patients with obesity reported significantly less internalized weight bias and significantly enhanced perceptions of positive communication with their medical providers after watching a video of a doctor who framed obesity as a treatable medical condition, compared with a video of a doctor who emphasized willpower.

“Recent research has identified the dominant role that biology (both genetics as well as homeostatic, hedonic, and executive brain systems) and environment, rather than willpower, play in the development of obesity and the resistance to weight loss,” wrote study authors Sara English, a medical student, and Michael Vallis, MD, associate professor of family medicine, both at Dalhousie University, Halifax, N.S. “Yet the false narrative that ideal or goal weight can be achieved by eating less and moving more using willpower continues to dominate the public narrative.”

The findings were published in Clinical Obesity.

Medical complexity

The public discussion generally places all responsibility for the health outcomes of obesity on the patient. As a result, patients with obesity face bias and stigma from the public and the health care system, wrote the authors.

This stigmatization contributes to increased mortality and morbidity by promoting maladaptive eating behaviors and stress. It also causes mistrust of health care professionals, which, in turn, leads to worse health outcomes and increased health care costs.

The 2020 Canadian clinical practice guidelines for obesity management in adults emphasize that obesity is complex and that nonbehavioral factors strongly influence it. They recommend that treatment focus on improving patient-centered health outcomes and address the root causes of obesity, instead of focusing on weight loss alone.

In the present study, Ms. English and Dr. Vallis evaluated how presenting obesity as a treatable medical condition affected participants’ internalized weight bias and their perceived relationship with their health care provider. They asked 61 patients with obesity (average age, 49 years; average body mass index, 41 kg/m2) to watch two videos, the first showing a doctor endorsing the traditional “eat less, move more approach,” and the second showing a doctor describing obesity as a chronic, treatable medical condition.

Nearly half (49.5%) of participants reported that their health care provider rarely or never discusses weight loss, and almost two-thirds of participants (64%) reported feeling stigmatized by their health care provider because of their weight at least some of the time.

After having watched each video, participants were asked to imagine that they were being treated by the corresponding doctor and to complete two measures: the Weight Bias Internalization Scale (WBIS), which measures the degree to which a respondent believes the negative stereotypes about obese people, and the Patient-Health Care Provider Communication Scale (PHCPCS), which assesses the quality of patient–health care provider communication.

Virtually all participants preferred the care provider in the video with the revised presentation of obesity. Only one preferred the traditional video. The video with the revised presentation was associated with significant reductions in internalized weight bias. Participants’ WBIS total score decreased from 4.49 to 3.36 (P < .001). The revised narrative video also had a positive effect on patients’ perception of their health care providers. The PHCPCS total score increased from 2.65 to 4.20 (P < .001).
