Stable vs unstable weight history, body-image, and weight concern in women of average body weight.

The focus of this study was the effect of unstable weight history on current body-image among women. Participants were 45 college women of average weight (median age = 23 yr.); 15 had stable weight histories, 15 had past lowest weights 15% or more below current weight, and 15 had past highest weights 15% or more above current weight. The women were assessed on perceptual and attitudinal measures of body-image and a self-report measure of preoccupation with weight. In comparison to women with stable weight histories, those with unstable weight histories indicated greater dissatisfaction with the shape and size of their bodies, expressed more negative body attitudes, and reported increased concern about weight. Women with high weight histories overestimated their frontal body-size and expressed greater dissatisfaction with frontal size than women with low weight histories, but the two groups did not differ significantly on any of the other dependent measures. Possible explanations for increased body-image disturbance and weight concern among women with unstable weight histories are presented.
