Societal attitudes toward obese persons are predominantly negative, and many health care professionals share these beliefs. This study compared attitudes toward obese persons of 67 US nurses to those of 107 Canadian nurses. Also, attitudes toward obesity were examined as a particular class of prejudice. A positive correlation was hypothesized between ethnic prejudice and prejudice regarding obese persons. Significant differences in attitudes toward obese patients were observed between the two groups on several questionnaire items, and the hypothesis was confirmed by the moderate r of .53 for US nurses. A surprising finding was a new target of ethnic prejudice: the Caucasian majority.
