[Parental influence in children's food preferences. The ESFUERSO study in two primary schools with different socioeconomic gradients].

Objective: Programs aimed at obesity prevention among elementary school age children have failed. In the present study, we analyzed the association between parental and child food preferences and determined whether this is influenced by the parents' gender and socio-economic status.

Material And Methods: We invited 300 children from a state elementary school (SES) and368 from a private middle class school (PMCS) to participate.
