The incidence of bulimic behavior in a secondary and University school population.

A survey questionnaire was instructor administered to high school and university students (n=1500) to assess the incidence of bulimic behavior. The questionnaire was tested and found to be a reliable and valid index for bulimic symptomatology. Respondents included 59% high school and 41% university level students. Data was evaluated by school, grade, sex, race, and interest area. Bulimic behavior was demonstrated at an incidence of 4.30% for the total sample. There was a nonsignificant higher incidence found in university (5.31%) compared to high school (3.98%) respondents. A significantly greater percentage of females responded with bulimic behavior than did males; however, there were no significant differences found between university and high school females. Bulimic behavior appeared to peak at Grades 11 and 13. Significantly more whites reported bulimic behavior than did blacks. Several academic interest areas not previously indicated in the literature may be more vulnerable to bulimic behavior.
