She completed her NIDA-funded predoctoral fellowship at Yale University in the Department of Psychiatry and her NHLBI-funded postdoctoral fellowship at the Stanford Prevention Research Center in the Stanford School of Medicine. Dr. Young-Wolff’s research interests include investigating how stress and trauma, genetic factors, and health-related policies shape disparities in the onset and course of drug and alcohol abuse, tobacco use, and psychiatric disorders. She is also interested in conducting research to inform the development of effective behavioral interventions for complex patients with multiple, co-occurring psychiatric and addictive disorders.

Studies

2021 Smoking and COVID-19 Onset and Severity in a US Integrated Healthcare Delivery System

This study examines 1) whether cigarette smoking and nicotine vaping are associated with elevated risk for onset of COVID-19 infection and worse disease severity, and 2) whether risks associated with cigarette smoking and nicotine vaping are greater among health disparity populations and those with smoking-related chronic health conditions.

2021 Health Equity Research Supplement to Conduct Focus Groups with Black and White Women who Self-Report Cannabis Use During Pregnancy

Qualitative data are critically needed to better understand knowledge gaps, preferences, and social and cultural factors that differentially contribute to prenatal cannabis use among Black and White women. To address these important gaps in knowledge, we will conduct race-matched virtual focus groups with Black and White pregnant women who self-report cannabis use during pregnancy to learn more about what drives prenatal cannabis use, women’s understanding of harms, and barriers to quitting to inform better education and intervention materials.

Assessing the Impact of Cannabis Legalization on Adolescent Cannabis Use and Cannabis-Related Health Conditions

Recreational cannabis legalization (RCL) has high potential to lead to increases in adolescent cannabis use and related health conditions, but few studies have examined this question and results are mixed. Using data from adolescents in KPNC''s large integrated health care delivery system from 2015-2023, we aim to: 1) Test whether RCL in California in 2018 is associated with increases in rates of cannabis use and related health conditions, 2) Examine whether post-RCL changes in rates of cannabis use and related health conditions vary among demographic and clinical subgroups, and 3) Conduct interviews with addiction medicine clinicians to understand how RCL impacts adolescent cannabis use and treatment from the provider perspective.

Maternal Marijuana Use During Pregnancy, Marijuana Legalization, and Adverse Obstetrical and Neonatal Outcomes: A 12-year Cohort Study (COVID-19 Revision)

As of March 26, 2020, there have been more than 80,000 cases and 1,000 deaths in the US due to COVID-19. Because it attacks the lungs, COVID-19 could be an especially serious threat to those who smoke or vape tobacco or cannabis. This study will use data from the Kaiser Permanente Northern California universal prenatal substance use screening program to examine whether women who use substances before or during pregnancy are at increased risk for COVID-19 onset and progression. We will also look at whether prenatal substance use rates rise during the pandemic overall or within certain subgroups, such as women with depression, anxiety, or low socioeconomic status.

Smoking as a Risk Factor for COVID-19 Onset and Severity

This pilot study will use data from Kaiser Permanente Northern California electronic health records to examine whether current and former smokers are at elevated risk for COVID-19 infection and disease severity relative to never smokers. We will also look at whether any associations between smoking status and COVID-19 onset or severity are moderated by smoking-related chronic conditions or socio-demographic factors.

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.

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.

Identifying Risk Factors for Prenatal Substance and Polysubstance Use

The overarching goal of this K01 study is to identify recent trends in prenatal substance use and develop data-driven, evidence-based, generalizable predictive models to identify women at greatest risk for continued substance use in pregnancy. Specifically, we aim to: 1) Comprehensively establish trends in prenatal substance and polysubstance use (2009-2017); 2) Develop predictive statistical models of clinical and demographic characteristics to identify women at greatest risk for continuing to use substances during pregnancy; and 3) Conduct qualitative interviews with women who quit vs. persisted in substance use during pregnancy.

Feasibility of Screening for Adverse Childhood Experiences (ACES) in a Prenatal Population

This study examines the feasibility and acceptability of adopting ACEs screening in two Kaiser Permanente Northern California women’s health clinics. Results of this patient- and clinician-focused study will inform the viability of implementing ACEs screening as part of usual prenatal care and can be used to develop improved screening protocols.

Impact of Health Reform on Smoking and Treatment Utilization

The overall objective of this study is to examine how the implementation of landmark health care legislation has impacted the population of smokers in a private health care delivery system, their treatment utilization, and their smoking cessation outcomes over time. New insured smokers through Medicaid expansion and CA exchanges are likely to be a vulnerable group, with a higher prevalence of comorbidities, and unique barriers to utilization of tobacco treatment. The study is designed to test whether newly insured patients have a higher percentage of comorbidities and differential use of tobacco cessation counseling. Further, the study will test whether variation in benefit plan and coverage among post-ACA new member smokers differentially impacts tobacco cessation counseling utilization and smoking cessation outcomes longitudinally.

Implementation and Effectiveness of a Perioperative Smoking Cessation Program

This study assesses the implementation and effectiveness of a perioperative smoking cessation intervention integrated into usual care for patients who smoke who are scheduled for elective surgery. Results will inform the feasibility of a real-world intervention in day-to-day practice that could be easily implemented in most perioperative settings.
