Young women who develop anorexia nervosa exhibit a persistently low premorbid body weight on average: A longitudinal investigation of an important etiologic clue.

Conclusions: The evidence that young women who subsequently show AN onset exhibit a low premorbid BMI on average is novel and suggests that etiologic models should incorporate this finding and selective prevention programs should target low-BMI adolescent girls. The finding that dieting, negative affect, affect-regulation eating expectances spiked immediately before emergence of AN is also novel and suggests that it might be useful for selective prevention programs to target these factors.
