Normal body, beautiful body: Discrepant perceptions reveal a pervasive ‘thin ideal’ from childhood to adulthood

We aimed to determine the developmental trajectory for the ‘thin ideal’ by evaluating discrepancies in objective ratings of female body attractiveness and normality in a sample of children and adults. One hundred and sixty Australian middle class male and female participants from four different age groups (range: 4–26 years) viewed sets of photos depicting female bodies that varied systematically on the dimension of width. Six photo sets were presented. Participants ranked three sets according to their perceptions of body normality and ranked the other three sets in terms of body attractiveness. Results indicated that for all age groups, attractiveness ratings were significantly thinner than normality ratings. These findings indicate that the thin ideal is already present in primary school children and remains stable into adulthood, with concerning implications for body dissatisfaction and related disorders. Further research is required to clarify the developmental origins of preferences for thinner-than-normal female bodies.

► Adults and children ranked female body images for normality and attractiveness.
► For all participants, attractiveness ratings were thinner than normality ratings.
► These findings show that a ‘thin ideal’ is already evident in childhood.
