The model 3 best fit model includes the same variables as model 2, but with the addition of EBF to 6 weeks or intention variables, as indicated for each column.
Bold text represents the significant values (p < 0.05).
BF, breastfeeding; CI, confidence interval; EBF, exclusive breastfeeding; HS, high school; OR, odds ratio.
