Study summary

The purpose of this study is to advance the scientific understanding of how a prenatal COVID-19 infection and associated psychological distress influences infant neurodevelopment. This project will aim to shed light on how families and child development are impacted by the current COVID-19 pandemic and will work to better support these families and children as they grow.

Read the detailed description

Prenatal exposure to maternal illness and stress has been widely associated with adverse neurodevelopmental outcomes, including deficits in cognition and socioemotional development. The principal goal of this project utilizes Magnetic Resonance Imaging (MRI), Electroencephalography (EEG), and a variety of behavioral measures to assess brain maturation and neurodevelopment among infants exposed prenatally to COVID-19 and associated high levels of stress. The planned experiments are effective in identifying brain markers that may contribute to resiliency in young infants, determining measures of stress response in relation to a maternal COVID-19 diagnosis, and characterizing the neurodevelopment of those infants born to mothers with a COVID-19 infection.

Specific goals include:

  1. To determine the prevalence of psychological distress in pregnant women with a confirmed COVID-19 diagnosis and to examine the extent to which existing high risk environments play a role in the susceptibility of heightened psychological distress.
  2. To examine the effects of prenatal distress and maternal illness/inflammation related to a maternal COVID-19 diagnosis on early structural and functional brain development.
  3. To characterize neural networks that may have been impacted by a maternal COVID-19 infection and related stress during pregnancy.
  4. To assess the early neurodevelopment outcomes of infants exposed to elevated prenatal stress related to a maternal COVID-19 diagnosis during pregnancy.

Groups and cohorts

  • COVID-19 Positive During Pregnancy

    Sixty mother-child dyads, who have or had a confirmed positive COVID-19 test during pregnancy, will be recruited and enrolled in this study. All women enrolled must be 18 years of age or older. Her child will go on to participate at 2-5 days of age, and again at 3-, 6-, 9-, 12- and 24-months of age.

    Other: No Intervention

  • COVID-19 Negative During Pregnancy

    Twenty-five mother-child dyads, who have a confirmed negative COVID-19 test during pregnancy will be recruited and enrolled in the study. Women without any SARS-CoV-2 positive test during pregnancy or any suspected COVID illness, even if not tested, will be enrolled. All women enrolled must be 18 years of age or older. Her child will go on to participate at 3-, 6-, 9-, 12- and 24-months of age.

What researchers measure

Primary outcomes

  1. Maternal stress associated with a SARS-CoV-2 diagnosis in pregnancy.

    Using the Perceived Stress Scale (scores can range from 0 to 40, with higher scores indicating greater stress).

    Time frame: 9 months (Third trimester - 6 month postnatal visit)

  2. Maternal mental health associated with a SARS-CoV-2 diagnosis in pregnancy.

    Using the Edinburgh Postnatal Depression Scale (scores range from 0-30, with higher scores indicating greater feelings of depression).

    Time frame: 30 months (Third trimester - 24 month postnatal visit)

  3. Inventory of maternal experience associated with a SARS-CoV-2 diagnosis in pregnancy.

    Using the Recent Life Events Questionnaire (indexes 30 common life events that encompass both positive and negative events).

    Time frame: 30 months (Third trimester - 24 month postnatal visit)

  4. Inventory of maternal experience related to healthcare associated with a SARS-CoV-2 diagnosis in pregnancy.

    Using the COPE Survey (50-item inventory of experiences for new or expectant mothers during the COVID-19 pandemic; psychometric properties and scoring procedures for this measure have yet to be determined).

    Time frame: 30 months (Third trimester - 24 month postnatal visit)

  5. Global cognitive ability of offspring

    Using the Mullen Scales of Early Learning at 3 months and 6 months postnatally. Five skill areas are measured: Gross Motor and four cognitive skills. These cognitive skill are summarized into an Early Learning Composite (scores are permitted to range from 20 to 80) - Fine Motor, Visual Reception, Receptive Language, and Expressive Language. The raw scores for each scale can be converted into age-adjusted normalized scores.

    Time frame: 3 months, 6 months, 9 months, 12 months, and 24 months

  6. Neural networks of offspring

    Using Electroencephalography at 3 months and 6 months postnatally

    Time frame: 3 months, 6 months, 9 months, 12 months, and 24 months

  7. Early structural and functional brain development of offspring

    Using MRI imaging, which will be obtained at 1-2 days of life

    Time frame: 1-2 days of life and/or 3-9 months of life
