Delayed Onset Lactogenesis II Predicts the Cessation of Any or Exclusive Breastfeeding
The Journal of Pediatrics, 05/18/2012
Brownell H et al. – Women experiencing delayed onset lactogenesis II [DLII] may be less able to sustain any and/or exclusive breastfeeding in the early postpartum period. Routine assessment of DLII in postpartum breastfeeding follow–up is warranted. Women with DLII may benefit from additional early postpartum interventions to support favorable breastfeeding outcomes.
Methods- The authors constructed multivariable logistic regression models using data from 2491 mothers enrolled in the prospective Infant Feeding Practice Study II cohort.
- Models included DLII, known risk factors for breastfeeding cessation (age, education, race, parity/previous breastfeeding, and exclusive breastfeeding plan), and potential confounders identified in bivariate analyses.
- Backward selection processes determined risk factor retention in the final model.
- DLII was associated with cessation of any and exclusive breastfeeding at 4-weeks postpartum (OR 1.62; CI 1.14-2.31; OR 1.62; CI 1.18-2.22, respectively); numerous independent risk factors qualified for inclusion in the multivariable model(s) and were associated with the outcome(s) of interest.
