Objectives : Whether delayed onset of lactogenesis (delayed OL) was linked to successful breastfeeding is unclear. We aimed to assess the association between delayed OL and breastfeeding practices in Chinese women.
Methods : Women form the TMCHC (Tongji Maternal and Child Health Cohort) study, who had OL assessment by face-to-face interview at day 4 postpartum and breastfeeding practices collected at 3, 6 and 12 months postpartum, were selected for the study. Poisson regression and Cox regression were used to identify the association between delayed OL and breastfeeding practices.
Results : Delayed OL was reported by 17.7% of the 2691 participants. After adjusting for maternal age, ethnicity, education, income, parity, pre-pregnancy BMI, GDM, gestational weight gain, gestational age, delivery mode, birth weight and breastfeeding information at day 1 postpartum, delayed OL was significantly associated with a higher risk of an inability to sustain full breastfeeding at 3 months postpartum (RR:1.31, 95% CI: 1.16, 1.48) and 6 months postpartum (RR:1.17, 95% CI: 1.07, 1.28), when compared with timely OL. Delayed OL was also significantly associated with early termination of any breastfeeding (HR:1.17, 95% CI: 1.01, 1.34) in adjusted model.
Conclusions : This study shows that women with delayed OL had a higher risk of suboptimal breastfeeding practices. Comprehensive efforts should be targeted towards women with delayed OL to promote breastfeeding.
