Kaiser Permanente Researcher Profiles

Lyndsay Ammon Avalos, PhD, MPH, is a research scientist at the Kaiser Permanente Northern California Division of Research. She holds a bachelor’s degree in animal physiology and neuroscience from UC San Diego, an MPH from Boston University, and a PhD in Epidemiology from UC Berkeley. She was an NIAAA pre-doctoral fellow through the training program at the Alcohol Research Group in Emeryville, Calif., and UC Berkeley’s School of Public Health. Her doctoral studies concentrated on the modifying effect of multinutrient supplements on the relationship between alcohol consumption during pregnancy and reproductive and perinatal outcomes. As a Building Interdisciplinary Research Careers in Women’s Health (BIRCWH) K12 scholar, Dr. Avalos’s research assessed the effectiveness of Kaiser Permanente’s Universal Perinatal Depression Screening program. Her current research broadly focuses on identifying genetic and environmental factors (e.g., alcohol use, medication exposure, ambient temperature, nutrition) during the perinatal period that influence maternal, fetal, and infant health.

Studies

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.

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.
