∘ All variables of interest were included in the full model in the initial step and then backward elimination procedure was applied to obtain the final model, using 5% critical value of χ² test for the appropriate degrees of freedom. * -2 log likelihood = 1637.86, d.f = 11
∘ Non-significant variables were maternal age, cesarean section, maternal education, infants' gender, when decided feeding method, parity, first feed, gestation week, mothers' job, if mothers attended antenatal classes, infant birth weight, if infants admitted to special care nursery?
