Predictors of Weight Bias in Exercise Science Students and Fitness Professionals: A Scoping Review

Does dissection influence weight bias among doctor of physical therapy students?

Anatomy with human dissection may help to develop respect for the human body and professionalism; however, dissection may worsen students' attitudes about body weight and adiposity. The purpose of this study was to measure weight bias among Doctor of Physical Therapy (DPT) students enrolled in gross anatomy and determine if, and how the experience of dissection impacts weight bias. Ninety-seven DPT students (70 University of Colorado [CU], 27 Moravian University [MU]) were invited to complete a survey during the first and final weeks of their anatomy course. The survey included demographic items, two measures of weight bias-the Modified Weight Bias Internalized Scale (M-WBIS) and the Attitudes Towards Obese Persons (ATOP) Scale-and open-ended questions for the students who participated in dissection (CU students) that explored attitudes about body weight and adiposity. At baseline, there were no significant differences (p > 0.202) in ATOP, M-WBIS, or BMI between the two universities. The mean scores on both the ATOP and M-WBIS indicated a moderate degree of both internalized and externalized weight bias. There were no significant changes in ATOP (p = 0.566) or M-WBIS scores (p = 0.428). BMI had a low correlation with initial M-WBIS scores (⍴ = 0.294, p = 0.038) and a high correlation with change scores in CU students (⍴ = 0.530, p = 0.011). Future studies should utilize the same measures of weight bias in other healthcare trainees to facilitate comparison and incorporate larger populations of DPT students.

Examining weight bias attitudes and obesity beliefs among undergraduate students

Objective: This cross-sectional study examined the weight bias attitudes and obesity beliefs of health science (HS), nursing, and pre-medicine undergraduate students. Methods: Using snowballing and convenience sampling strategies, students (N = 139) completed an online survey, including a 24-item Antifat Attitudes Scale (AFAS) and eight-item Belief About Obese Persons (BAOP) scale. Results: HS students have higher weight bias than nursing and pre-medicine students combined (M = 43.45, SD = 10.75), t(137) = -2.45, p = .016). A negative correlation exists between AFAS and BAOP suggesting high weight bias influences a belief that obesity is controllable. Gender positively predicted weight bias attitudes (ß = -11.43, t = -4.33, p < .001) and obesity beliefs (ß = 3.75, t = 3.01, p = . 003). Conclusions: Findings confirm that HS students have weight bias attitudes. This supports undergraduate curricular changes on obesity etiology that may improve treatment plans of individuals who are obese.
