EIBF, early initiation of breastfeeding; EBF, exclusive breastfeeding; CBF-1, continued breastfeeding at 1 year; CBF-2, continued breastfeeding at 2 years; SD, standard deviation. Included those who worked as a professional, technician, manager, clerical, sales, or industrial worker.
Values are presented as adjusted odds ratio (95% confidence interval). The final model for EIBF included perceived birth size, birth pattern, type of delivery, and skin-to-skin contact (Archer-Lemeshow goodness-of-fit 0.689); The final model for EBF included infant’s age, birth pattern, mother’s occupation, household wealth index, and mother’s smoking status (Archer-Lemeshow goodness-of-fit 0.508); The final model for CBF-1 included infant’s age, birth pattern, mother’s education, mother’s occupation, household wealth index, antenatal care visits, type of delivery, place of delivery, and time of the first postnatal visit (Archer-Lemeshow goodness-of-fit 0.660); The final model for CBF-2 included infant’s age, mother’s education, household wealth index, and time of the first postnatal visit (Archer-Lemeshow goodness-of-fit 0.883). EIBF, early initiation of breastfeeding; EBF, exclusive breastfeeding; CBF-1, continued breastfeeding at 1 year; CBF-2, continued breastfeeding at 2 years. The sample sizes of each group are different since models differed by outcome (see Age was not included as a variable in the analyses of EIBF. Fitted as a continuous variable in the analyses of CBF-1 (values: 12, 13, 14, and 15 months) and CBF-2 (values: 20, 21, 22, and 23 months) so that the adjusted odds ratio reflects the effect of a 1-month increase in age. Included those worked as a professional, technician, manager, clerical, sales, and industrial worker.
