The purpose of the Prenatal Experiences and Pediatric Sleep (PEAPS) research study is to learn more about how experiences during pregnancy may influence later infant behaviors and sleep patterns. Sleep quality has been related to physical, emotional and behavioral health in children and adults, and thus we’d like to learn more about what may influence infant sleep.
How will the study be conducted?
The study will use home visits, sleep observations, and questionnaires in order to learn about factors that may influence the development of infant sleep patterns.
During the second and third trimesters, we will ask participants to complete questionnaires and a series of daily experience surveys. These questions will ask about participants’ backgrounds, experiences, attitudes, and feelings.
24 weeks of pregnancy
Participant will be asked to complete an in-person interview at the Center for Developmental Science . We will ask for recalled details about habits and routines during pregnancy, including substance use. Participants will also be asked to complete a card sorting task with heart rate monitoring.
For those participants who give birth at UNC Hospital, in Chapel Hill, North Carolina, nursing staff will obtain samples of umbilical cords. The umbilical cord sampling occurs after birth and does not affect routine medical care.
3 months after birth
Participants will complete questionnaires. During home visits, we will film mothers interacting with their infants. We will also collect saliva samples from the infants. Additionally, we will monitor infants’ sleep for one week. To do this, we will ask participants to help us by filming babys’ bedtime and sleep through the night for one night. Also, babies will wear heart rate monitors on their chests and watch devices that record movement and activity.
9 months after birth
We will visit the homes one last time. We will provide more questionnaires and film mothers interacting with their infants. We will collect infant saliva samples. All activities will be filmed and babies will wear heart rate monitors on their chests.
