Self-esteem and mental health characteristics especially among lean students surveyed by University Personality Inventory.

In recent years, various investigators have indicated an increase in the number of eating disorders. A similar tendency has been observed among university students. The purpose of the present study is to clarify the self-esteem and mental health characteristics of the lean students who suffer from latent eating disorders. We examined 2132 responses to the University Personality Inventory obtained from students who entered Nagoya University in 1995. We analyzed the mental health conditions of the lean students after categorizing the subjects into lean, normal and obese group by body mass index. As a result, the following results were obtained. Lean male students presented with more subjective symptoms than normal and obese students, and extremely lean male students had more subjective symptoms. Lean female students had fewer subjective symptoms than lean male students and no particular differences from normal female students. It is suggested that male and female students had different criteria for self-esteem with regard to body shape. The lean female students were medically ill and formed a latent or borderline latent group with anorexia nervosa. However, they had a similar degree of health awareness as normal students.
