Aim 1: Characterize the relationship between prenatal and postnatal environmental exposures and the infant gut microbiome across the first year of life.
Aim 2: Evaluate the associations among prenatal and postnatal toxicant exposures, the infant gut microbiome, maternal caregiving, and infant neurocognitive and social-emotional development.
1) Data collection for the Microbiome, Environment, and Neurodevelopmental Delay study has continued throughout the year, and we now have 65 mother-infant pairs enrolled in the postnatal follow up and an additional 15 scheduled for upcoming newborn visits;
2) We have worked to cultivate strong relationships with research participants and this has resulted in a successful retention rate of 85%;
3) Our research staff have received training in infant neurological assessments and have been certified as reliable on the NNNS;
4)We have hired an additional staff member with a background in Neuroscience to assist in data collection and inputting for the project;
5) We have successfully piloted and implemented our protocols for the age 6 and 12 month follow ups;
6) We have worked synergistically with Project 1 staff to complete home visits where dust and other data on environmental exposures are collected;
7) We have successfully collected and stored over 2000 samples of stool, urine, blood, and buccal cells;
8) Co-Project Lead Rodriguez has developed a supplemental measure of infant nutritional intake which we have added to our 3, 6, and 12 month follow up visits.
9) We have added an additional measure to assess mother’s cognitive abilities.
Our plans for the next reporting period include continued recruitment, enrollment and data collection. We will initiate our first 18-month follow-up visits during the next project period and we will devise and implement our mother child interaction coding scheme. We will continue to review progress with the investigative team and make adjustments (especially to recruitment strategies) if necessary. Our demonstrated ability to retain 85% of our recruited mother infant pairs is highly significant and bodes well for the outcome of Project 2. Thus, our primary plans during the next reporting period are to continue to address our Specific Aims by recruiting participants and conducting our study as planned. A secondary goal of the next project period is to increase our production of manuscripts; currently Co-Project Leads Brennan and Rodriguez have three papers in development with this dissemination goal in mind. The publication of manuscripts is supported by data entry and verification that is on track for each time point.
