Laura Jelliffe-Pawlowski, PhD, MS, is a Professor. Prof. Jelliffe-Pawlowski’s research interests focus on understanding and addressing the drivers and consequences of adverse pregnancy outcomes with a special emphasis on preterm birth and associated racial/ethnic and socioeconomic inequities. Her work is highly transdisciplinary and looks at the interplay of biomolecular, social, and policy factors in observed patterns and outcomes. Her teaching and mentorship activities reflect this transdisciplinary approach with an emphasis on motivating the translation of research findings into action.

 

Prof. Jelliffe-Pawlowski leads a number of statewide, national, and international research efforts funded by the National Institutes of Health, the Bill and Melinda Gates Foundation, the March of Dimes, the State of California, and other entities. These includes, notably, the “Healthy Outcomes of Pregnancy for Everyone (HOPE)” consortium and study which focuses on understanding the experience of pregnant people and their infants pre- and post-COVID 19 pandemic. HOPE examines how biomolecular, social, and community factors affect the well-being and outcomes of mothers and infants and includes enrollment during pregnancy with outcome follow-up to 18-months after birth. Other ongoing projects include, for example, the NIH funded “Prediction Of Maturity, Morbidity, and Mortality in PreTerm Infants (PROMPT)”, study which focuses on examining the metabolic profiles of newborns with early preterm birth and associated outcomes, the “Transforming Health and Reducing PerInatal Anxiety through Virtual Engagement (THRIVE)”, randomized control trial (RCT), funded by the State of California which examines whether digital cognitive behavior therapy delivered by mobile app can assist in reducing anxiety symptoms in pregnant people and also examines participant acceptability of the application. Ongoing efforts also include leading the “California Prediction of Poor Outcomes of Pregnancy (CPPOP)” cohort study which focuses on investigating multi-omic drivers of preterm birth. The study interrogates biomolecular signals associated with preterm birth and includes full genome sequencing and mid-pregnancy biomolecular signaling related to metabolic, immune, stress, and placental function in hundreds of pregnancies with and without preterm birth. 

 

Prior to her joining NYU Meyers, Prof. Jelliffe-Pawlowski was a Professor of Epidemiology & Biostatistics, Chief of the Division of Lifecourse Epidemiology, a Professor in the Institute of Global Health Sciences, and Director of Discovery and Precision Health for the UCSF California Preterm Birth Initiative in the University of California San Francisco (UCSF) School of Medicine. She has a lifetime appointment as an Emeritus Professor of Epidemiology & Biostatistics in the UCSF School of Medicine and continues to work closely with the new Center for Birth Equity at UCSF. Prior to her appointment at UCSF, she was a leader at the Genetic Disease Screening Program within the California Department of Public Health. 

 

Prof. Jelliffe-Pawlowski efforts have been highlighted in numerous academic and lay articles including in the New York Times, in WIRED Magazine, in the Atlantic, on CNN, and on MSNBC. In 2023, she was recognized by Forbes Magazine as one of the top 50 over 50 Innovators in the United States. She is also a Phase I and Phase II Bill and Melinda Gates Foundation Grand Challenges awardee for her work in the United States and Uganda which focused on the development and validation of newborn metabolic profile as a novel measure of gestational age in infants.

Singh, N., Baer, R. J., Swaminathan, M., Saurabh, S., Sparks, J. A., Bandoli, G., Flowers, E., Jelliffe-Pawlowski, L. L., & Ryckman, K. K. (2021). Surgery for Obesity and Related Diseases, 17(2), 406-413. 10.1016/j.soard.2020.09.016
Abstract
Abstract
Background: Autoimmune rheumatic diseases (ARDs) and bariatric surgery are each risk factors for adverse birth outcomes. To date, no study has investigated their combined impact on birth outcomes. Objectives: The objective of this study was to evaluate the impact of bariatric surgery on pregnancy outcomes in women with an ARD. As a secondary comparison, we assessed the risk of bariatric surgery on the same outcomes in women without an ARD. Setting: Records maintained by the California Office of Statewide Health Planning and Development. Methods: This cohort study included infants born between 20–44 weeks of gestation in California between 2011–2018. Risks of adverse pregnancy outcomes were evaluated for women with a history of bariatric surgery as compared to women without a history of bariatric surgery, stratified by ARD, using log-linear regression with a Poisson distribution. Results: The study included 3,574,165 infants, of whom 10,823 (0.3%) were born to women who had an ARD and 13,529 (0.38%) to women with a history of bariatric surgery. There were 155 infants born to women (0.0043%) with both an ARD and a history of bariatric surgery. In women with an ARD and without bariatric surgery, the prevalence of preterm births was 18%, compared to 17.4% in women with both ARD and bariatric surgery; in women without ARD but with prior bariatric surgery, the prevalence of preterm births was 13.7%, compared to 8.2% in women without bariatric surgery. Except for neonatal intensive care unit (NICU) admissions, women with an ARD and history of bariatric surgery were not at a statistically increased risk of having other adverse pregnancy outcomes as compared to women with an ARD and no history of bariatric surgery. Conclusion: Our study shows that women with ARD already have a high occurrence of several adverse birth outcomes, and this was not further increased by a history of bariatric surgery. The infants born to women with a history of ARD and bariatric surgery were admitted to the NICU significantly more than the infants born to women with an ARD and no history of bariatric surgery.

Racial Disparities in the Rates of and Indications for Cesarean Delivery in California: Are They Changing over Time?

Teal, E. N., Anudokem, K., Baer, R. J., Jelliffe-Pawlowski, L., & Mengesha, B. (2021). American Journal of Perinatology, 41(1), 31-38. 10.1055/s-0041-1740071
Abstract
Abstract
Objective  The aim of this study was to assess whether racial disparities in rates of and indications for cesarean delivery (CD) between non-Hispanic Black and non-Hispanic White birthing people in California changed from 2011 to 2017. Methods  This was a retrospective cohort study using a database of birth certificates linked to discharge records. Singleton term live births in nulliparous Black and White birthing people in California between 2011 and 2017 were included. Those with noncephalic presentation, placenta previa, and placenta accreta were excluded. CD rate and indication were obtained from birth certificate variables and International Classification of Diseases codes. Differences in CD rate and indication were calculated for Black versus White individuals using univariable and multivariable logistic regression and adjusted for potential confounders. Results  A total of 348,144 birthing people were included, 46,361 Black and 301,783 White. Overall, 30.9% of Black birthing people underwent CD compared with 25.3% of White (adjusted relative risk [aRR]: 1.2, 95% confidence interval [CI]: 1.2-1.3). From 2011 to 2017, the CD rate fell 11% (26.4-23.7%, p < 0.0001) for White birthing people and 1% for Black birthing people (30.4-30.1%, p = 0.037). Over the study period, Black birthing people had a persistent 1.2- to 1.3-fold higher risk of CD and were persistently more likely to undergo CD for fetal intolerance (aRR: 1.1, 95% CI: 1.1-1.2) and less likely for active phase arrest or arrest of descent (aRRs: 0.9 and 0.4; 95% CIs: 0.9-0.9 and 0.3-0.5). Conclusion  The CD rate decreased substantially for White birthing people and minimally for Black birthing people in our cohort over the study period. Meanwhile, disparities in CD rate and indications between the two groups persisted, despite controlling for confounders. Although care bundles for reducing CD may be effective among White birthing people, they are not associated with reduction in CD rates among Black birthing people nor improvements in racial disparities between Black and White birthing people. Precis  Despite increasing attention to racial inequities in obstetric outcomes, there were no changes in disparities in CD rates or indications in California from 2011 to 2017. Key Points Black birthing people are more likely to undergo CD than White despite controlling for confounders. There are unexplained differences in CD indication among Black and White birthing people. These disparities persisted from 2011 to 2017 despite increasing efforts to decrease CD rates in CA.

Abstract
Abstract
Objectives: To investigate racial/ethnic differences in rehospitalization and mortality rates among premature infants over the first year of life. Study design: A retrospective cohort study of infants born in California from 2011 to 2017 (n = 3,448,707) abstracted from a California Office of Statewide Health Planning and Development database. Unadjusted Kaplan–Meier tables and logistic regression controlling for health and sociodemographic characteristics were used to predict outcomes by race/ethnicity. Results: Compared to White infants, Hispanic and Black early preterm infants were more likely to be readmitted; Black late/moderate preterm (LMPT) infants were more likely to be readmitted and to die after discharge; Hispanic and Black early preterm infants with BPD were more likely to be readmitted; Black LMPT infants with RDS were more likely to be readmitted and die after discharge. Conclusions: Racial/ethnic disparities in readmission and mortality rates exist for premature infants across several co-morbidities. Future studies are needed to improve equitability of outcomes.

Risk of Early Birth among Women with a Urinary Tract Infection: A Retrospective Cohort Study

Baer, R. J., Nidey, N., Bandoli, G., Chambers, B. D., Chambers, C. D., Feuer, S., Karasek, D., Oltman, S. P., Rand, L., Ryckman, K. K., & Jelliffe-Pawlowski, L. L. (2021). AJP Reports, 11(1), E5-E14. 10.1055/s-0040-1721668
Abstract
Abstract
Objective The aim of the study is to evaluate the risk of preterm birth (PTB, <37 weeks) and early term (37 and 38 weeks) birth among women with an emergency department (ED) visit or hospitalization with a urinary tract infection (UTI) by trimester of pregnancy. Methods The primary sample was selected from births in California between 2011 and 2017. UTIs were identified from the ED or hospital discharge records. Risk of PTB, by subtype, and early term birth were evaluated by trimester of pregnancy and by type of visit using log-linear regression. Risk ratios were adjusted for maternal factors. Antibiotic usage was examined in a population of privately insured women from Iowa. Results Women with a UTI during pregnancy were at elevated risk of a birth <32 weeks, 32 to 36 weeks, and 37 to 38 weeks (adjusted risk ratios [aRRs] 1.1-1.4). Of the women with a diagnostic code for multiple bacterial species, 28.8% had a PTB. A UTI diagnosis elevated risk of PTB regardless of antibiotic treatment (aRR 1.4 for treated, aRR 1.5 for untreated). Conclusion UTIs are associated with early birth. This association is present regardless of the trimester of pregnancy, type of PTB, and antibiotic treatment.

McLemore, M. R., Berkowitz, R. L., Oltman, S. P., Baer, R. J., Franck, L., Fuchs, J., Karasek, D. A., Kuppermann, M., McKenzie-Sampson, S., Melbourne, D., Taylor, B., Williams, S., Rand, L., Chambers, B. D., Scott, K., & Jelliffe-Pawlowski, L. L. (2021). Journal of Racial and Ethnic Health Disparities, 8(5), 1273-1280. 10.1007/s40615-020-00889-2
Abstract
Abstract
This project examines risk and protective factors for preterm birth (PTB) among Black women in Oakland, California. Women with singleton births in 2011–2017 (n = 6199) were included. Risk and protective factors for PTB and independent risk groups were identified using logistic regression and recursive partitioning. Having less than 3 prenatal care visits was associated with highest PTB risk. Hypertension (preexisting, gestational), previous PTB, and unknown Women, Infant, Children (WIC) program participation were associated with a two-fold increased risk for PTB. Maternal birth outside of the USA and participation in WIC were protective. Broad differences in rates, risks, and protective factors for PTB were observed.

Socioeconomic status, diabetes, and gestation length in Native American and White women

Ross, K. M., Oltman, S., Baer, R., Altman, M., Flowers, E., Feuer, S., Gomez, A. M., & Jelliffe-Pawlowski, L. (2021). Health Psychology : Official Journal of the Division of Health Psychology, American Psychological Association, 40(6), 380-387. 10.1037/hea0001072
Abstract
Abstract
OBJECTIVE: "Diminishing returns" of socioeconomic status (SES) suggests that higher SES may not confer equivalent health benefits for ethnic minority individuals as compared to White individuals. Little research has tested whether diminishing returns also affects Native Americans. The objective of this study was to determine whether higher SES is associated with lower diabetes risk and longer gestational length in both Native American and White women, and whether SES predicts gestational length indirectly via diabetes risk. METHOD: A sample of 674,014 Native American and White women was drawn from a population-based California cohort of singleton births (2007-2012). Education, public health insurance status, gestational length, and diabetes diagnosis were extracted from a state-maintained birth cohort database. Covariates were age, health behaviors, pregnancy variables, residence rurality, and prepregnancy body mass index. RESULTS: In logistic regression models, the race by SES interaction (both education and insurance status) was associated with diabetes risk. Compared to high-SES White women, high- and low-SES Native American women had highest and equivalent diabetes risk. In path analyses, the race by SES interaction indirectly predicted gestational length through diabetes, ps < .001. For White women, an indirect effect of diabetes was detected, ps < .001, such that higher SES was associated with reduced risk for diabetes and thus longer gestational length. For Native American women, no indirect effect was detected, ps > .067. CONCLUSIONS: Among Native American women, higher SES did not confer protection against diabetes or shorter gestational length. These findings are consistent with the diminishing returns of SES phenomenon. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Twin chorionicity and zygosity both vary with maternal age

Yeaton-Massey, A., Sparks, T. N., Norton, M. E., Jelliffe-Pawlowski, L., & Currier, R. J. (2021). Prenatal Diagnosis, 41(9), 1074-1079. 10.1002/pd.5997
Abstract
Abstract
Objective: To determine the ratio of dichorionic (DC) to monochorionic (MC) twins by maternal age. Methods: We reviewed all twin pregnancies undergoing first trimester screening (FTS) with nuchal translucency from April 2009 to December 2012 with sonographic determination of chorionicity. Cases were linked to newborn screening (NBS) results and zygosity estimated based on rates of fetal sex discordance. The ratio of DC to MC placentation by maternal age was calculated. Results: We identified 11,351 twin pregnancies with FTS and documented chorionicity. Among these, 7861 (64.2%) had linked data on FTS and NBS to allow estimation of zygosity based on neonatal sex. Of these, 1464 (18.6%) were MC and 6406 (81.4%) DC. The MC twin rate remained constant while the DC twin rate increased with maternal age until 40 years. At <20 years, 55% of twin pregnancies were monozygotic (MZ), as compared to 29% at > 40 years. Of MZ twins, 38% were DC at < 20years, while 53% were DC at >40 years. Conclusions: Our data suggest a relationship of both zygosity and chorionicity with maternal age. DZ twinning increased with maternal age, while among MZ twins, the proportion that were DC also increased with maternal age.

Adverse Pregnancy Outcomes by Degree of Maternal Serum Analyte Elevation: A Retrospective Cohort Study

Yeaton-Massey, A., Baer, R. J., Rand, L., Jelliffe-Pawlowski, L. L., & Lyell, D. J. (2020). AJP Reports, 10(4), E369-E379. 10.1055/s-0040-1716741
Abstract
Abstract
Objective  The aim of this study was to evaluate rates of preterm birth (PTB) and obstetric complication with maternal serum analytes > 2.5 multiples of the median (MoM) by degree of elevation. Study Design  Retrospective cohort study of singleton live-births participating in the California Prenatal Screening Program (2005-2011) examining PTB and obstetric complication for α-fetoprotein (AFP), human chorionic gonadotropin (hCG), unconjugated estriol (uE3), and inhibin A (INH) by analyte subgroup (2.5 to < 6.0, 6.0 to < 10.0, and ≥ 10.0 MoM vs. < 2.5 MoM). Results  The risk of obstetric complication increased with increasing hCG, AFP, and INH MoM, and were greatest for AFP and INH of 6.0 to <10.0 MoM. The greatest risk of any adverse outcome was seen for hCG MoM ≥ 10.0, with relative risk (RR) of PTB < 34 weeks of 40.8 (95% confidence interval [CI]: 21.7-77.0) and 13.8 (95% CI: 8.2-23.1) for obstetric complication. Conclusions  In euploid, structurally normal fetuses, all analyte elevations > 2.5 MoM confer an increased risk of PTB and, except for uE3, obstetric complication, and risks for each are not uniformly linear. These data can help guide patient counseling and antenatal management.

Cohort study of respiratory hospital admissions, air quality and sociodemographic factors in preterm infants born in California

Steurer, M. A., Costello, J., Baer, R. J., Oltman, S. P., Feuer, S. K., Pacheco-Werner, T., Rogers, E., Jankowska, M. M., Block, J., McCarthy, M., Pantell, M. S., Chambers, C., Ryckman, K. K., & Jelliffe-Pawlowski, L. L. (2020). Paediatric and Perinatal Epidemiology, 34(2), 130-138. 10.1111/ppe.12652
Abstract
Abstract
Background: Preterm infants suffer from respiratory morbidity especially during the first year of life. Objective: To investigate the association of air quality and sociodemographic indicators on hospital admission rates for respiratory causes. Methods: This is a retrospective cohort study. We identified all live-born preterm infants in California from 2007 to 2012 in a population-based administrative data set and linked them to a data set measuring several air quality and sociodemographic indicators at the census tract level. All sociodemographic and air quality predictors were divided into quartiles (first quartile most favourable to the fourth quartile least favourable). Mixed effect logistic models to account for clustering at the census tract level were used to investigate associations between chronic air quality and sociodemographic indicators respiratory hospital admission during the first year of life. Results: Of 205 178 preterm infants, 5.9% (n = 12 033) were admitted to the hospital for respiratory causes during the first year. In the univariate analysis, comparing the first to the fourth quartile of chronic ozone (risk ratio [RR] 1.29, 95% confidence interval [CI] 1.21, 1.37), diesel (RR 1.10, 95% CI 1.02, 1.17) and particulate matter 2.5 (RR 1.07, 95% CI 1.01, 1.14) exposure were associated with hospital admission during the first year. Following adjustment for confounders, the risk ratios for hospital admission during the first year were 1.53 (95% CI 1.37, 1.72) in relation to educational attainment (per cent of the population over age 25 with less than a high school education) and 1.23 (95% CI 1.09, 1.38) for poverty (per cent of the population living below two times the federal poverty level). Conclusions: Among preterm infants, respiratory hospital admissions in the first year in California are associated with socioeconomic characteristics of the neighbourhood an individual is living in.

Early pregnancy prediction of gestational diabetes mellitus risk using prenatal screening biomarkers in nulliparous women

Snyder, B. M., Baer, R. J., Oltman, S. P., Robinson, J. G., Breheny, P. J., Saftlas, A. F., Bao, W., Greiner, A. L., Carter, K. D., Rand, L., Jelliffe-Pawlowski, L. L., & Ryckman, K. K. (2020). Diabetes Research and Clinical Practice, 163. 10.1016/j.diabres.2020.108139
Abstract
Abstract
Aims: To evaluate the clinical utility of first and second trimester prenatal screening biomarkers for early pregnancy prediction of gestational diabetes mellitus (GDM) risk in nulliparous women. Methods: We conducted a population-based cohort study of nulliparous women participating in the California Prenatal Screening Program from 2009 to 2011 (n = 105,379). GDM was ascertained from hospital discharge records or birth certificates. Models including maternal characteristics and prenatal screening biomarkers were developed and validated. Risk stratification and reclassification were performed to assess clinical utility of the biomarkers. Results: Decreased levels of first trimester pregnancy-associated plasma protein A (PAPP-A) and increased levels of second trimester unconjugated estriol (uE3) and dimeric inhibin A (INH) were associated with GDM. The addition of PAPP-A only and PAPP-A, uE3, and INH to maternal characteristics resulted in small, yet significant, increases in area under the receiver operating characteristic curve (AUC) (maternal characteristics only: AUC 0.714 (95% CI 0.703–0.724), maternal characteristics + PAPP-A: AUC 0.718 (95% CI 0.707–0.728), maternal characteristics + PAPP-A, uE3, and INH: AUC 0.722 (0.712–0.733)); however, no net improvement in classification was observed. Conclusions: PAPP-A, uE3, and INH have limited clinical utility for prediction of GDM risk in nulliparous women. Utility of other readily accessible clinical biomarkers in predicting GDM risk warrants further investigation.
