Objective To identify the factors associated with an adequate perception of
body image in relation to body weight.
Material and methods An observational, cross-sectional study was conducted
in a representative sample of the European Union (7155 men and 8077 women).
Body Mass Index (BMI) was grouped into four categories, perceived body ima
ge was assessed using the nine silhouettes drawing: scheme. A multivariable
logistic regression model for each sex: was used to adjust for potentially
confounding variables.
Results Underweight men and women classified themselves better than other g
roups (92.9% of correct answers among men and 79.3% among women). Overall,
women classified themselves better than men (57.6% vs. 32.7%).
Discussion Perceived body image as a method of assessment for body weight h
as different validity depending on sociodemographic or attitudinal categori
es. Perceived body image as an estimate of the nutritional status has a lim
ited individualized application. Thus, perhaps it could be applied as a pro
xy measure of adiposity among slim males and among slim and overweight fema
les, but not among the other groups.
