Prejudices are hostile or negative attitudes towards members of identifiable groups based solely on their membership in that group. Consequently, prejudices lead to stigmatization, which leaves physical and psychological consequences on the individual. Physical appearance is an attribute that society puts on a growing emphasis, and the frequency of prejudice and discrimination against the obese is increasing. Prejudices occur already in pre-school children, but the way they are learning them is not yet clear. The objective of this study was to determine how mother's attitudes and dissatisfaction with their body image are associated with the attitudes of their children who are 5 to 7 years old. A total of 100 pairs of mothers and children particiated in the study. Mothers were questioned for negative attitudes towards obese people, the perception of their body image through silhouettes, and avoiding behaviors related to the body image, while for the children we used silhouettes to examine preferences for different body weights (thin, normal weight or overweight). The results showed that children chose the silhouette with normal body weight as the preferred one, except when the girls where choosing, where they equally selected the thin silhouette and the silhouette with normal body weight. It was also shown that the preference of choosing in children has almost no relationship with the body mass index, the avoiding behaviors related to body image and negative attitudes towards obese in their mothers.
