About
Overview
The purpose of this research study is to examine what women eat and the reasons for their food choices during pregnancy and after their baby is born. The study will also examine how thoughts, values and beliefs related to food influence a woman’s health during pregnancy and the postpartum period, along with the health of her baby.
Study Organization
This study is funded and led by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) of the National Institutes of Health, in collaboration with the University of North Carolina and The Emmes Corporation.

Anna Maria Siega-Riz, PhD, RD
Dr. Siega-Riz, a nutritional epidemiologist, uses a multidisciplinary team perspective as a way to address complex problems such as prematurity, fetal programming, racial disparities and obesity. She has been involved in several large cohort studies involving pregnant women, children and Hispanics as well as one multi-centered intervention study for preventing type 2 diabetes in middle school children.
Myles Faith, PhD
Dr. Faith studies familial influences on the development of child eating patterns and obesity. His work also focuses on lifestyle interventions for childhood obesity treatment/prevention, having received funding from the NIH and the American Diabetes Association to investigate these issues in 4 to 8 year old youth. He served on the Nutrition Committee for the American Heart Association’s Council on Nutrition, Physical Activity and Metabolism (NPAM), and was a standing member of the NIH Psychosocial Risk and Disease Prevention Study Section.
Kyle Burger, MPH, RD, PhD
Dr. Burger’s primary area of research focuses on eating behavior, how it evolves, implicit drivers and explicit perceptions of food intake. Specifically, how these aspects of ingestive behavior relate to habitual consumption, executive control, and weight regulation. His labs examines these questions using direct and indirect measures of food intake, brain imaging techniques (functional MRI), and a variety of behavioural and self-report measures.
Grace Shearrer, PhD
Dr. Shearrer studies the homeostatic and hedonic motivations to eat. Specifically, how hedonic signals influence homeostatic mechanisms both neurologically and hormonally.

Debbie Shim – Research Assistant
Franca Barton, MS
Franca Benedicty Barton is a biostatistician with a 35-year record of NIH-sponsored collaboration with leading medical investigators conducting research that has resulted in changing clinical practice, as well as advancing medical knowledge and statistical practice. Her early-career collaboration with the NEI-sponsored, multi-center Early Treatment Diabetic Retinopathy Study in the 1980s-90s resulted in widely expanded use of laser photocoagulation for many thousands of people with diabetic retinopathy in the US and around the world, still a standard of care for DR (Refs #1-3). Assuming broader study leadership in the 1990s, her collaboration with the NHLBI-sponsored Multicenter Study of Hydroxyurea in Sickle Cell Anemia (MSH), under the direction of Johns Hopkins’ Samuel Charache, resulted in US-FDA approval in 1996 of a revised formulation--Droxia®--designed specifically for this orphan disease, which was rapidly approved around the world (Refs #4-5).
