aModel 1: Crude analysis. Each variable was separately entered into the model. Household equivalent income (HEI) was calculated as household income divided by the square root of the number of people per household.

bModel 2: For multiple regression, child sex, maternal education, maternal employment status, HEI, maternal age, and maternal nutritional status were forced into the model, and selected by backward stepwise selection with a 0.35 of significant level of removal from the model. Only the selected variables were used for calculating aOR.
