Jennifer Abbas

PhD Student - Jennifer Abbass

Evaluating the Effectiveness of a Co-Parenting Breastfeeding Support Intervention (COSI) on Exclusive Breastfeeding Rates at Twelve Weeks Postpartum

Jennifer Abbas will evaluate COSI delivered to first-time mothers and fathers in the early postpartum period on exclusive breastfeeding rates at three months postpartum. This intervention consists of a co-parenting workbook and video, a breastfeeding booklet, and access to a secure website with information on breastfeeding and co-parenting. Secondary outcomes being evaluated include breastfeeding duration, partner support and the co-parenting relationship.

Kimberley Allen

PhD Student - Kimberley Allen

A Randomized Controlled Trial Evaluating Lanolin for the Treatment of Nipple Pain Among Breastfeeding Women

Kimberley Allen’s research interests include the evaluation of nursing interventions aimed to improve health outcomes for breastfeeding mothers and their infants. For her dissertation, Allen is conducting a randomized controlled trial to evaluate the effect of the application of lanolin (a commonly used ointment) for the treatment of nipple pain among breastfeeding women. From this clinical trial, she hopes to better understand how the use of lanolin may impact maternal perception of breastfeeding pain and breastfeeding outcomes, such as duration and exclusivity.

Trish Unruh

PhD Student - Trish Unruh

The Relationship Between Infant Sleep Location and Postpartum Depression

Trish Unruh will compare postpartum depression rates between breastfeeding mothers who bed share, room share and sleep apart from their infant and examine causal pathways. Her dissertation could help inform mothers and health care professionals on strategies to decrease the risk of postpartum depression by providing interventions that promote sleep for both the mother and baby.
