aFrequency of consumption of a food group controlling for gender, type of school and soda intake (Logistic regression model: Overweight = one food group + gender + type of school + soda consumption).
bSame as Model 1 plus additional simultaneous adjustments for frequency of consumption of all the other six food groups. (Logistic regression model: Overweight = Grains + Nuts + Vegetables + Fruits + Meat/Fish/Eggs + Dairy + LNDF + gender + type of school + soda consumption).
