Abstract: Objective To investigate the first lactation time and delayed lactation of parturient in the Zhumadian area, and provide a reference for the lactation guidance of parturient in this area. Methods The parturient who gave birth in the Department of Obstetrics and Gynecology of Zhumadian Second Hospital of Traditional Chinese Medicine and Zhumadian Central Hospital from March 1, 2021, to February 27, 2022, were selected as the survey subjects, and their prenatal conditions （including gestational diabetes mellitus, pregnancy hypertension, anxiety, depression, and prenatal breastfeeding education） and postpartum interventions （including mother-infant rooming, early mother-infant contact, early breast acupoint massage, breastfeeding guidance, breast stimulation with low-frequency pulse rehabilitation therapy instrument, and psychological intervention） were obtained by questionnaire. The descriptive analysis was performed on first lactation time and delayed lactation, and the effects of the prenatal condition and postpartum interventions on delayed lactation were analyzed by univariate and multivariate analysis methods. Results A total of 1 185 valid respondents were obtained. The first lactation time was less than 24 h in 352 cases, 24-47 h in 293 cases, 48-71 h in 272 cases, and ≥72 h in 268 cases. The incidence rate of delayed lactation was 22.62%. Multivariate Logistic regression analysis showed that anxiety （OR=2.438）, depression （OR=2.691）, prenatal breastfeeding education （OR=0.569）, early mother-infant contact （OR=0.953）, early breast acupoint massage （OR=0.689）, breastfeeding guidance （OR=0.559）, breast stimulation with low-frequency pulse rehabilitation therapy instrument （OR=0.463）, and psychological intervention （OR=0.723） were the influencing factors of delayed lactation. Conclusions The incidence of delayed lactation in the Zhumadian area is high, which is closely related to a variety of lactation interventions, such as prenatal breast education, early mother-infant contact, early breast acupoint massage, breastfeeding guidance, breast stimulation with low-frequency pulse rehabilitation therapy instrument, and psychological intervention. According to the individual situation of pregnant women, we can strengthen the lactation intervention during pregnancy and postpartum to promote the improvement of breastfeeding rate.
