Decoding difficulties of facial expression of emotions in mothers of children suffering from developmental obesity

The relationship between developmental obesity and emotional problems has been particularly studied by Bruch. According to this author, the main reason for early-onset obesity has to be found in the difficulty of some mothers to adequately distinguish between emotional manifestations and the child's real need for food. In this paper an experiment was carried out in order to test the relationship between developmental obesity and poor ability to recognize facial expressions of some basic emotions.

A group of 20 mothers whose children suffered from serious early-onset obesity (experimental group) and another group of 20 mothers, whose children had slight overweight problems arising long after the first year of life (control group), were tested. Both mothers and their children were asked to recognize a set of facial expressions of emotions. 42 slides of facial expressions of emotions (anger, sadness, disgust, surprise, fear, happiness and neutral faces) were presented to subjects who were asked to mark on an answer sheet the name of the emotion expressed by the actor's face.

A significant difference between the groups was found: a larger number of errors in the recognition of facial expression of emotions was made by mothers and their children in the experimental group. Furthermore a positive linear correlation between the number of errors made by the mothers and that made by their children was present.

The findings do support Bruch's clinical observations. Further studies concerning other emotional signs (either nonverbal or verbal) are needed in order to assess the importance of emotional decoding difficulties in developmental obesity.
