Objective: To determine influential factors for delayed breastfeeding initiation.
Methods: Using questionnaires to collect the data of 950 pregnant women and infants’ feeding
practices in Changsha, Hunan, logistic regression and decision tree model were used to determine
influential factors for delayed breastfeeding initiation.
Results: Mothers with timely breastfeeding initiation were 594 (62.5%), and those with delayed
breastfeeding initiation accounted for 356 (37.5%). Mothers with timely breastfeeding initiation
were more likely to use exclusive breastfeeding than those with delayed breastfeeding initiation
(P<0.05). Four risk factors were found by logistic regression model and decision tree model,
including cesarean delivery, using feeding-bottle before breastfeeding initiation, falling ill, and
vomiting during pregnancy. Receiver operating characteristic curve showed no significant difference
in the predictive effect of the 2 models (Z=0.142, P=0.889). Conclusion: Cesarean delivery, using feeding-bottle before initiation of breastfeeding, and poor
physical condition during pregnancy exert negatively effects on breastfeeding initiation. Health
workers should help mother to timely initiate breastfeeding and enhance their confidence in
