Omega Tots Follow-up Study

This study follows up with participants in the original Omega Tots Research Study. Participants received a nutritional supplement or placebo powder for 6 months. This study is a brief, one-time postal survey to learn more about how these children continue to grow and learn.

LEAF (Lifestyle and Early Achievement in Families)

LEAF wants to find out if different things that happen during pregnancy – like stress, smoking, weight gain, medication use, or other lifestyle factors – might affect how preschool-aged children grow and act. We’re hoping results from this study will be able to help lead to better healthcare for children in the future.

Improving National Survey Questions/Moms2Moms Follow-up Study

Our objective is to develop and evaluate a short set of questions to capture infant feeding practices. We will follow up with previous Moms2Moms study participants to gather more information about these practices. We hope to support future, high-quality research and public health surveillance of maternal and child health that uses federal survey data.

Play and Grow

This study wants to know how caregivers play and talk to their children, and if this affects the way children grow and act. Children and their families meet with our research team 4 different times over two years, starting when the child is about 18 months old.

What We Have Learned

From Our Breast Milk Sharing Study

We wanted to know if moms with young babies know about milk sharing (when a woman shares her own breast milk with another woman, or feeds her own child breast milk from other women).

From Our Moms2Moms Study

Choosing how long to breastfeed your child and when to start feeding your child solid foods can be hard. We wanted to know if these things are related to how children grow during the first year of life.

This study found that babies who were breastfed for longer gained weight more slowly than babies who were breastfed for shorter times. This slower weight gain may be important for preventing childhood obesity later on. We are still trying to understand why longer breastfeeding helps slow weight gain. One possibility is that a natural hormone in breast milk, called leptin, helps infants know when they are full and done eating.


Our Current Projects

Growth in Children Born Preterm

We want to develop evidence-based strategies for guiding clinicians and families in recognizing and preventing obesity in children. Looking at 20,000 children, we will try to determine the prevalence and timing of the development of obesity in early childhood among preterm children, compared to term children, and identify the best intervention window.

Preemie Tots

Preemie Tots is a research study that is interested in learning about the behavior and development of toddlers who were born prematurely. For this study we examined whether a fatty acid supplement benefited toddlers’ development.

Life After Pregnancy Study (LAPS)

Our long-term goal is to develop better guidance for first-time mothers as they prepare for the arrival of their baby, and better supportive advice in addressing the common challenges that arise after coming home from the hospital. For this study, moms complete a home survey.
