METHOD: Variables related to the girls' weight status, psychological health, body satisfaction, maternal child feeding practices, and family environment are included in a hierarchical regression model predicting the emergence of dieting in girls. Interactions of girls' weight status with other variables in the model are also included in the last step. RESULTS: Results indicate that the model accounts for 45% of the variance in the outcome scores and that variables across constructs have significant contributions to the model. Results also show that girls' weight status, both independently and as an interaction term, accounts for a large proportion of variance in this model. CONCLUSION: Weight status at age 5 years is a critical factor related to the emergence of dieting in young girls.
