Epigenetic Impact of Breastfeeding on Infant Stress Regulation
Classic animal studies have shown that maternal care of rat mothers e.g. licking and grooming and arched back nursing, impacts offspring outcomes such as behavior, development, and stress regulation. These outcomes persist over subsequent generations. Epigenetics, the study of how environmental influences affect gene expression, mediates these effects. In this session we will discuss and explore how similar epigenetic mechanisms in humans possibly relate to the protective effects of breastfeeding and maternal tactile stimulation on infant stress reactivity.
This lecture was originally offered as part of the GOLD Lactation Conference 2019.
Dr. Hawes provides clinical services in the Neonatal Intensive Care Unit and at the Perinatal and Postpartum Clinic at the Center for Children and Families at Women & Infants Hospital, where she treats women and their partners experiencing perinatal mood and anxiety issues. Treatment includes individual and family psychotherapy. She is an assistant professor (adjunct) in the Department of Pediatrics at The Warren Alpert Medical School of Brown University. She trained in adult psychiatry and mental health at the University of Rhode Island and is board certified in adult psychiatric-mental health advanced practice nursing. Her research, clinical work, and lectures focus on stress and trauma related to the premature birth experience. In addition she studies the relationship between nursing practice and parent and infant outcomes; nurse-patient interaction; the healthcare work environment and provider and patient outcomes; and the epigenetics of stress.

Objective 1: Describe basic epigenetic processes;
Objective 2: Explain the relationship between DNA methylation and infant HPA stress response; and
Objective 3: Describe the impact of exclusive breastfeeding on DNA methylation and decreased cortisol reactivity in infants.

How much time do I have to view the presentations?
- The viewing time will be specified for each product. When you purchase multiple items in your cart, the viewing time becomes CUMULATIVE. Ex. Lecture 1= 2 weeks and Lecture Pack 2 = 4 Weeks, you will have a total of 6 weeks viewing time for ALL the presentations made in that purchase.
- Time for viewing the talks begins once you purchase the product. For Live Webinars & Symposiums, the viewing period begins from when the live event takes place. Presentations can be accessed 24/7 and can be viewed as many times as you like during the viewing period.
What are bundled lectures?
- Presentations may be available individually or via a bundled package. Bundled lectures are a set of lectures that have been put together based on a specific category or topic. Some lectures will be available in both individual and lecture form, whereas others will be available only via a bundled lecture pack.
Will there be Handouts?
- YES! Each lecture comes with a PDF handout provided by the Speaker.
Some lectures include a Q&A, what does that mean?
- During our online conferences, presentations that occur live are also followed by a short 15 minute Question & Answer Session. The Speaker addresses questions that were posted by Delegates during the presentation. We include the recording of these Q&A Sessions as a bonus for you.
How can I receive a Certificate?
- If this presentation offers a certificate, once you are done viewing the lecture or the lectures within a bundle, submit your attendance record in order to be able to download your certificate. You'll be able to see which credits are offered for the lecture by hovering over the "Credits Available" link within the "Speakers & Topics" tab.
