Studies

Preconception and Prenatal Health Impacting Factors and Child Health

The study will recruit a diverse cohort of 1,800 pregnant individuals, the conceiving partner, their resulting child, and will follow all of them at multiple visits after the child is born to contribute to the Environmental influences on Child Health Outcomes (ECHO) Program. We will examine the role of in utero exposure to psychological distress and substance use on child growth, adiposity, obesity, and neurodevelopment (ND) and the extent to which prenatal lifestyle factors and neighborhood factors may mitigate these associations. We will clarify the joint effects of maternal prenatal dietary patterns and the 24-hour movement and child growth, obesity, and ND and whether metabolomic signatures prenatally, at birth, and postnatally mediate these associations. There will also be a preconception pilot study to explore the role of maternal and paternal lifestyle factors on infant health to identify critical time periods to intervene on to prevent upstream risk factors for childhood obesity and ND.

Evaluation of the EmbrACE Intervention for Pregnant Adults with a History of Adverse Childhood Experiences

Feasibility study of a 6-week virtual intervention for pregnant women with high adverse childhood experience (ACE) exposure and moderate to moderate-severe depression to reduce perinatal depression symptoms. Study will enroll and randomize participants to the 6-week virtual EmbrACE program or to receive health education resources (active control).

The Impact of Racial Residential Segregation on the Mental Health of Pregnant Women

We will create a large diverse cohort of more than 360,000 pregnant Black, Hispanic, Asian and white women to: examine the relationship between racial residential segregation and prenatal depression, anxiety and trauma (Aim 1); and prenatal depressive severity (Aim 2). Analyses will be stratified by race/ethnicity. This study has important public health, clinical and policy implications for addressing racial/ethnic mental health inequities in a vulnerable population, pregnant women.

mHealth Mindfulness Intervention for Pregnant Black and Latina Women at Risk of Postpartum Depression

Comparing the Effects of Prenatal Depression and its Treatment on Developmental Outcomes of the Offspring

This study will test the hypothesis that the underlying prenatal depression and use of SSRIs are independent risk factors for adverse neurodevelopmental outcomes. The aims of this study are: 1) evaluate the effect of untreated prenatal depression, compared to no prenatal depression, on neurodevelopmental outcomes of the offspring, after adjustment for confounders; 2) evaluate the effect of treatment for prenatal depression with SSRIs on neurodevelopmental outcomes of the offspring; 3) on a subsample of 2,000 children, evaluate prenatal depression and its treatment in parental interviews to identify less severe neurodevelopmental outcomes.

Racial/Ethnic Disparities in Perinatal Depression Treatment Utilization

The study will characterize racial/ethnic differences in perinatal depression treatment utilization, treatment engagement, and continued care by assembling a retrospective cohort of KPNC members entering prenatal care between 2012-2016. The study will also identify barriers to and facilitators of treatment utilization and opportunities for improvement in care delivery.

Impact of In Utero Marijuana Exposure on Neurodevelopment, Behavior and Mental Health: A Longitudinal Birth Cohort Study

This study will investigate whether maternal prenatal marijuana use increases the risk of impairments in a child’s executive functioning and mental health, after accounting for other factors such as tobacco, alcohol, and other drug use; socioeconomic status, and maternal mental health postpartum. We will look at both the independent effects of prenatal marijuana use and the synergistic effects of concomitant substance use as well as differential effects by infant sex.

Preventing Postpartum Depression: Exercise as Medicine

This intervention study will randomize 200 postpartum women at increased risk of postpartum depression to an eHealth physical activity intervention and assess the efficacy of the intervention on increasing physical activity and decreasing postpartum depressive symptoms. Additionally, this study will identify actionable areas for implementation of this eHealth intervention in an integrated health care delivery system.

Prenatal Depression and Antidepressant Exposure: Effects on Child Speech and Language Disorders

The aims of this study are to 1) Assess the relationship between untreated prenatal depression and the risk of speech and language disorders of offspring; 2) Compare the effectiveness of treatment of prenatal depression on speech and language disorders of offspring; 3) Evaluate whether the timing and duration of SSRI use during pregnancy is related to child speech and language disorders; and 4) Assess the extent to which these relationships differ by infant sex.

Maternal Marijuana Use During Pregnancy, Marijuana Legalization, and Adverse Obstetrical and Neonatal Outcomes: A 12-year Cohort Study

The goal of this application is to examine the association between maternal marijuana use during pregnancy and adverse obstetrical and neonatal outcomes. We aim to: 1) Examine trends in prenatal marijuana use following the legalization of marijuana for recreational purposes in California; 2) Assess whether maternal marijuana use during pregnancy is associated with the risk of adverse maternal health and pregnancy outcomes; and 3) Assess whether maternal marijuana use during pregnancy is associated with the risk of adverse fetal and neonatal outcomes.

Moderate Hypertension in Pregnancy: Safety and Effectiveness of Treatment

The aims of this study are to: 1. Estimate risks of adverse pregnancy outcomes after antihypertensive medication exposure compared to a) untreated chronic or gestational hypertension, and b) healthy pregnancies with neither hypertension nor treatment. We will study: a) Maternal outcomes including cesarean delivery, postpartum hemorrhage, pre-eclampsia, and ICU admission; and b) Neonatal outcomes including preterm birth, small-for-gestational age, intensive care unit (NICU) stay, congenital malformations, and perinatal death. 2.Examine how risks vary for different antihypertensive agents. 3.Examine how risks vary according to the degree of blood pressure control achieved during treatment. 4. Examine how risks vary by obesity, GDM status and race/ethnicity.

Impact of Folate, Obesity and Genetics on Maternal Depression

Research is desperately needed to inform safe and effective interventions for the prevention and treatment of maternal depression. An important first step to understanding whether nutrition may serve as an intervention and improve maternal mental health, is to elucidate the relationship between nutrition and depression during the peripartum period (during pregnancy and after). The aims of this study will address a gap in knowledge and provide insights into the relationship between nutrition and maternal depression which will take us a few steps closer to identifying whether dietary modifications or supplements may provide an inexpensive, easily modifiable intervention for the prevention of peripartum depression.

Climate Change and Health: Assessing the Risk of Preterm Delivery

The overall objective of this study is to examine the impact of climate change on the risk of preterm delivery (PTD) by using a case-crossover study design utilizing members of KPNC. In our first aim, we will assess the relationship between apparent temperature and PTD. Estimates will be adjusted for important air pollutants. In our second aim we will determine whether maternal factors (age, race/ethnicity and SES as measured by medicaid status) impact the relationship between apparent temperature and preterm delivery. Finally, we will explore whether additional maternal factors may impact the the relationships in the first aim. These additional factors include hypertension, smoking, alcohol use, medication use, gestational diabetes, depression, and pre-pregnancy BMI.
