Examining weight bias attitudes and obesity beliefs among undergraduate students.

: This cross-sectional study examined the weight bias attitudes and obesity beliefs of health science (HS), nursing, and pre-medicine undergraduate students. : 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. HS students have higher weight bias than nursing and pre-medicine students combined ( = 43.45,  = 10.75), (137) = -2.45,  = .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 ( -11.43, -4.33 < .001) and obesity beliefs ( 3.75,  3.01 = . 003). : 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.
