Kaiser Permanente Researcher Profiles


Assiamira Ferrara, MD, PhD is a Senior Research Scientist at the Kaiser Permanente Northern California Division of Research. Her primary focus has been the epidemiology of and translational research related to diabetes and gestational diabetes (GDM). Dr. Ferrara and colleagues have adapted the Diabetes Prevention Program intervention for use in women with GDM as well as pregnant overweight or obese women during the prenatal and postpartum periods to achieve weight management and reduce the risk of type 2 diabetes. Dr. Ferrara also conducts cohort studies of pregnant women and their offspring to identify early risk factors for diabetes and obesity. Dr. Ferrara’s life course approach to diabetes and obesity prevention is aimed in reducing the risk factors for these chronic conditions early in life. 

She has also led the establishment and maintenance of the KPNC Gestational Diabetes and Pregnancy Glucose Tolerance Registry since its inception in 1997. Dr. Ferrara collaborated with researchers across the nation to further the understanding of sex disparities in the quality of health care for people with diabetes in an attempt to explain the higher risk of cardiovascular mortality in women with diabetes relative to men. She has also worked to determine the safety of diabetes medications in regards to cancer risks.

    Comparative Effectiveness of Diabetes Prevention Strategies in Women with Gestational Diabetes Mellitus

    This cluster-randomized lifestyle intervention trial assesses the effect of an organizational-level intervention on weight management in patients with gestational diabetes mellitus (GDM). Randomization will occur at the medical center level. Forty-four medical centers of Kaiser Permanente Northern California will participate and data will be collected for more than 2,400 pregnant women with GDM. The intervention will be compared to usual care.

    Study to Assess the Incidence of Type 1 Diabetes in Young Adults

    This project with multiple principal investigators will address the following aims: 1) Develop and implement a case ascertainment strategy for the rapid, timely and complete identification of new onset diabetes cases among young adults; 2) Develop and implement procedures for the measurement of diabetes autoantibodies; 3) Establish a diverse, population-based registry of incident cases of diabetes among young adults; 4) Determine the incidence of type 1 diabetes.

    Early Life Exposure to Endocrine Disrupting Chemicals and Child Growth, Adiposity, and Neurodevelopment

    We hypothesize that in-utero exposures to commonly used endocrine disrupting chemicals, such as PFCs and PBDEs, individually and/or in combination, have adverse effects on child obesity and neurodevelopment through possible common pathways. Our aims are: Aim 1. To evaluate whether in-utero exposures to maternal PFCs and PBDEs, individually and/or in combination, are associated with infant growth, adiposity and neurodevelopment. Aim 2. To evaluate whether in-utero PFCs and PBDEs exposures are associated with metabolic determinants of obesity and neurodevelopment . Aim 3. To explore whether in-utero PFCs and PBDEs exposures are associated with infant patterns of DNA methylation. Aim 4. To identify infant, maternal and paternal factors that modify the association of exposure to in-utero PFCs and PBDEs exposures and with infant growth, adiposity and neurodevelopment.

    Appropriate Gestational Weight Gain in Overweight/Obese Women

    Among overweight/obese pregnant women, we propose to develop and evaluate a randomized diet and physical activity intervention tailored to mothers and feasible in a health plan setting, with the goal of ameliorating inappropriate gestational weight gain.

    Prenatal Bisphenol A Exposure and Risk of Gestational Diabetes

    This study will enroll 3,350 pregnant women during their first trimester, among whom a prospective nested case-control study of 300 gestational diabetes cases and 600 controls will be conducted to examine the association between early pregnancy levels of bisphenol-A (BPA) and the risk of GDM in the second trimester, as well as the association between BPA and high levels of metabolic markers of insulin resistance and liver enzymes, and the risk of having a large for gestational age (LGA) infant.

    Translational Diabetes Prevention in GDM

    This is a lifestyle intervention project tailored to pregnant and postpartum women with gestational diabetes (GDM) and designed to reduce risk factors for type 2 diabetes. The intervention will start during pregnancy soon after GDM diagnosis and will continue postpartum. It will be delivered by individual telephone counseling contacts and brief in-person counseling sessions. Patients will be randomly assigned to a lifestyle intervention or usual medical care. Among GDM patients we propose to implement and evaluate an intervention of diet and physical activity tailored to be practical in health plan settings and for postpartum mothers, with the primary goals of: a) reaching pre-pregnancy weight if women had normal pre-pregnancy weight; or b) reaching a 5% reduction from pre-pregnancy weight if overweight or obese prior to pregnancy.
