Brief summary
The Promoting Healthy Brain Project (PHBP) is part of the Lurie Children's Hospital Strategic Research Initiative on Perinatal Origins of Childhood Disease: Research & Prevention at the Maternal-Fetal Interface. The overall purpose of the PHBP is to test whether reducing maternal stress during pregnancy is associated with improved neurodevelopment in the first year of life. This will be tested via a randomized controlled trial (n = 100) of a technology and mindfulness enhanced prenatal stress-reduction intervention (Mothers and Babies; MB).
Detailed description
The Promoting Healthy Brain Project (PHBP) aims to improve infant neurodevelopmental trajectories by intervening on the fetal environment. The PHBP will experimentally test whether reducing prenatal maternal stress is associated with improved neurodevelopment in the first year of life. A randomized controlled trial (RCT) of a technology and mindfulness-enhanced prenatal maternal stress-reduction intervention (The Mothers and Babies Course; MB), compared to usual prenatal care. Prospective evaluation of infant neurodevelopmental outcomes will take place through infant age 24 months. Participants assigned to the intervention group will be offered the 12-session MB intervention, a well-studied intervention that will include new mindfulness practice enhancements designed to promote practice of awareness and attention to the present moment. MB visits will be delivered 1-on-1 by a trained facilitator in an open and nonjudgmental way, and will be offered in-person, over the phone, and/or by video chat. Throughout the intervention, all participants (intervention group and control group) will also wear a wireless, smart health sensing device (BioStamp Sensor - nPoint Device) that will measure heart rate and motion. Mothers' heart rate variability and self-reported stress and emotion will be monitored using the BioStamp Sensor and brief smartphone surveys. For mothers in the intervention group, patterns of prolonged stress will trigger a just-in-time adapted intervention (JITAI) that will be delivered to mothers' smartphones. The booster intervention will include activities that will enhance skills learned in the MB course. All participants will complete self-report measures of prenatal maternal stress, emotion, depression, and skills related to the intervention (e.g., mindfulness). Infant neurodevelopmental health will be measured via brain and behavioral indicators of self-regulation, including performance-based indicators of executive function and corollary prefrontal cortex maturation and dimensional phenotypes of disruptive behavior, particularly irritability.
Interventions
BEHAVIORALMothers and Babies (MB) Course
The Mothers and Babies course (MB) is a 12-session manualized stress-reduction intervention that will be delivered to participants, prenatally, with an integrated technology suite designed for timely detection and response to maternal stress.
BEHAVIORALJust in Time Intervention (JITI) Content
Participants will also receive additional MB intervention content in the form of just-in-time text messages, which will be sent to participants' smartphones every other day for up to 12 weeks. During the current trial, participants will receive text message prompts with links to additional stress reduction content based on a combination of their objective (sensor) and subjective (EMA) stress responses from the previous day.
DEVICEBiostamp nPoint Device
During the intervention period, participants will be asked to wear the BioStamp nPoint sensor, daily, while engaging in their usual activities (e.g., sleep, showering, exercise). The BioStamp Sensor is a thin, wearable patch, equipped with wireless high-range 6-axis gyroscope + accelerometer, and sEMG and ECG sensors, that adheres to the skin using a disposable medical-grade adhesive sticker (with adhesive similar to Band-Aid).
