Background: Weight bias has been documented throughout society among clinicians as well as obese persons. Purpose: The purpose of this study was to assess Health Educators' professional philosophies, knowledge of obesity, and beliefs in a just world (meaning that people get what they deserve) in relation to their attitudes toward people who are obese. Methods: Members of the Health Education Directory, a national listserv, were solicited to participate as a convenience sample for this study. Participants completed a survey that consisted of (1) an item to assess Health Educators' professional philosophies; (2) items from the Anti-fat Attitudes Scale, the Global Belief in a Just World Scale, and the Obesity Knowledge Scale; and (3) demographic items (i.e., age, sex, educational attainment, and personal weight status). Results: Results revealed that participants embracing the behavior change philosophy scored higher on the Anti-fat Attitudes Scale than participants espousing other philosophies. Those who believed more strongly in a just world were more likely to hold negative attitudes toward obese persons. Discussion: When people feel stigmatized by Health Educators, prevention efforts are compromised. Translation to Health Education Practice: This research provides insights that will enable Health Educators to better serve their overweight and obese clients.
