    Abstract
  •   Objective  To explore the incidence of delayed onset of lactogenesis Ⅱ (DOL Ⅱ) in premature mothers and its relationship with feeding status in preterm infants and breastfeeding psychology in mothers, and provide some reference for the management.  Methods  A total of 804 premature mothers were selected between January 2022 and June 2023 in the 2nd Affiliated Hospital of Wenzhou Medical University. After propensity score matching, there are 267 cases each in the DOL Ⅱ and non-DOL Ⅱ groups. The differences between the DOL Ⅱ and non-DOL Ⅱ groups in preterm hospital feeding, maternal feeding attitude, breastfeeding self-efficacy and breastfeeding duration were analyzed.  Results  The incidence of DOL Ⅱ in premature mothers was 36.3% (292/804). The duration of gastric tube, started oral feeding time and breastfeeding rates at discharge were (7.85±1.98) d, (6.65±1.53) d and 39.7% (106/267) respectively in DOL Ⅱ group, with (7.19±1.67) d, (5.89±1.21) d and 45.3% (121/267) in non-DOL Ⅱ group, which were all had significantly differences (P < 0.05). The average daily lactation, infant feeding attitude score and breastfeeding self-efficacy scale were (28.65±7.85) mL, (61.44±13.13) points and (48.17±12.41) points respectively in DOL Ⅱ group, with (30.75±7.94) mL, (68.43±14.52) points and (52.27±13.74) points in non-DOL Ⅱ group, which were all had significantly differences (P < 0.05). The breastfeeding rate was 22.8% (61/267) in DOL Ⅱ group and 36.3% (97/267) in non-DOL Ⅱ group in the corrected age of 12 months. The difference in breastfeeding duration time between the two groups was statistically significant (P < 0.05).  Conclusion  Preterm infants whose mothers have DOL Ⅱ have longer started oral feeding time, and lower breastfeeding rates at discharge. DOL Ⅱ mothers have lower infant feeding attitudes, breastfeeding self-efficacy and shorter breastfeeding duration.
