Control group had no education. Two weeks later, mothers again completed the questionnaires. The data were analyzed by the spss15 for windows, for analysis of covariance (ANCOVA) and Pearson correlation tests. Results:Eleven per cent of mothers failed to perceive their overweighed child as overweight, and 83/3% of mothers after education, accepted that their children are overweight these were mothers who failed to perceive their overweight child as overweight before education. The results of analysis of cov- ariance (ANCOVA) were significant between means of two group's mothers attitudes, and proved a significant difference between two mean in elements of HBM (p<0/0001). Demographic factors showed no significant difference between two groups.
