The usefulness of body image tests in the prevention of eating disorders.
OBJECTIVE
Individual psychological factors such as mental conditions and self-esteem and family relational factors are thought to be predisposing factors in the development of eating disorders. In this study, we conducted a survey of 12-15 year-old public junior high school students to extract factors related to abnormal eating behavior and determine what information could be used by schools to prevent eating disorders.


METHODS
Self-descriptive surveys were distributed and collected during homeroom time at school. The survey consisted of the 26-item Eating Attitude Test (EAT-26) to measure the degree of abnormal eating behavior, Stunkard, Sorensen and Schlusinger's Body Image Scale to determine predisposing factors, the Family Adaptability and Cohesion Scale III (FACES III), General Health Questionnaire (GHQ), and Rosenberg's Self-Esteem Scale. 483 students (263 boys and 220 girls) participated in the survey. School-year height and weight data was used to calculate BMI.


RESULTS
Approximately 7% of girls and 3% of boys showed clear indications of abnormal eating behavior. We found no direct relationship between abnormal eating behavior and family factors in this study, but an indirect relationship was suggested through other factors such as psychological complaints and self-esteem. There were relationships between abnormal eating behavior and the individual factors of psychological complaints, current and ideal body image, and low self-esteem. Furthermore, cluster analysis showed that there were students with high BMI who thought of themselves as fat, as well as students who perceived themselves as fat despite having average BMI. These students had a high frequency of abnormal eating behaviors, a great deal of psychological complaints, and low self-esteem.


CONCLUSIONS
An understanding of BMI, along with body image, is essential for students who feel that they are overweight. Schools can practice preventative education by teaching these students about healthy body weight and by screening for the eating disorders that have become so rampant in our thin-worshiping culture.
