"She should support me, she's my doctor:" Patient perceptions of agency in contraceptive decision-making in the clinical encounter in Northern California.

INTRODUCTION: Agency in contraceptive decision-making is an essential aspect of reproductive autonomy. We conducted qualitative research to investigate what agency means to patients seeking contraceptive care to inform the development of a validated measure of this construct. METHODOLOGY: We held four focus group discussions and seven interviews with sexually-active individuals assigned female at birth, ages 16-29 years, recruited from reproductive health clinics in Northern California. We explored experiences in contraceptive decision-making during the clinic visit. We coded data in ATLAS.ti and by hand, compared codes across three coders, and used thematic analysis to identify salient themes. RESULTS: The sample mean age was 21 years, with 17% of participants identifying as Asian, 23% as Black, 27% as Latinx, 17% as Multiracial/other, and 27% as white. Overall, participants reported active and engaged decision-making in their recent contraceptive visit but noted experiences that had undermined their agency in the past. They described how non-judgmental care allowed them to communicate openly, affirming their ability to make their own decisions. However, several mentioned how unexpected contraceptive side effects after the visit had reduced their sense of agency over their decision in retrospect. Several participants, including those who identified as Black, Latinx, and/or Asian, described prior experiences where pressure to use a contraceptive method had undermined their agency and where they had switched providers to regain agency over their contraceptive decisions. DISCUSSION: Most participants were aware of their agency during contraceptive visits and how it varied in different experiences with providers and the healthcare system. Patient perspectives can help to inform measurement development and ultimately the delivery of care that supports contraceptive agency.

"It was just one moment that I felt like I was being judged": Pregnant and postpartum black Women's experiences of personal and group-based racism during the COVID-19 pandemic.

BACKGROUND: Racial inequities in maternal and child health outcomes persist: Black women and birthing people experience higher rates of adverse outcomes than their white counterparts. Similar inequities are seen in coronavirus disease (COVID-19) mortality rates. In response, we sought to explore the intersections of racism and the COVID-19 pandemic impact on the daily lives and perinatal care experiences of Black birthing people. METHODS: We used an intrinsic case study approach grounded in an intersectional lens to collect stories from Black pregnant and postpartum people residing in Fresno County (July-September 2020). All interviews were conducted on Zoom without video and were audio recorded and transcribed. Thematic analysis was used to group codes into larger themes. RESULTS: Of the 34 participants included in this analysis, 76.5% identified as Black only, and 23.5% identified as multiracial including Black. Their mean age was 27.2 years [SD, 5.8]. Nearly half (47%) reported being married or living with their partner; all were eligible for Medi-Cal insurance. Interview times ranged from 23 to 96 min. Five themes emerged: (1) Tensions about Heightened Exposure of Black Lives Matter Movement during the pandemic; (2) Fear for Black Son's Safety; (3) Lack of Communication from Health Care Professionals; (4) Disrespect from Health Care Professionals; and (5) Misunderstood or Judged by Health Care Professionals. Participants stressed that the Black Lives Matter Movement is necessary and highlighted that society views their Black sons as a threat. They also reported experiencing unfair treatment and harassment while seeking perinatal care. CONCLUSIONS: Black women and birthing people shared that exposure to racism has heightened during the COVID-19 pandemic, increasing their levels of stress and anxiety. Understanding how racism impacts Black birthing people's lives and care experiences is critical to reforming the police force and revising enhanced prenatal care models to better address their needs.

A qualitative exploration of experiences accessing community and social services among pregnant low-income people of color during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic has been associated with increased social and economic stressors among pregnant individuals. While community and social services have been available to mitigate stressors in pregnancy (e.g. food insecurity and financial hardship) and reduce the risk of adverse maternal outcomes, it is unclear how the pandemic impacted access to these resources, particularly in communities of color with lower incomes. OBJECTIVE: To examine the experiences accessing community and social service resources during the COVID-19 pandemic among pregnant people of color with low incomes. DESIGN: Participants for this COVID-related qualitative study were recruited from two sources-a prospective comparative effectiveness study of two models of enhanced prenatal care and the California Black Infant Health Program between August and November of 2020. METHODS: We conducted 62 interviews with Medicaid-eligible participants in California's Central Valley. During their interviews, study participants were asked to share their pregnancy-related experiences, including how they felt the pandemic had affected those experiences. RESULTS: We identified two broad themes: challenges with accessing community and social service resources during the pandemic and opportunities for improving access to these resources. Sub-themes related to challenges experienced included difficulty with remote access, convoluted enrollment processes for community and social services, and problems specific to accessing COVID-19 resources (e.g. testing). Sub-themes related to opportunities to improve access included leveraging instrumental support from perinatal staff and informational (e.g. practical) support from other community programs and pregnant peers. Participant recommendations included leveraging opportunities to improve client experiences through increased transparency and better patient-provider communication. CONCLUSION: This study highlights some important trends that emerged with the rollout of remote service delivery for social services among a vulnerable population. Many participants were able to leverage support through other programs and perinatal staff. These individuals identified additional opportunities to improve client experiences that can inform the future implementation of support services for pregnant people.

Structural racism is associated with adverse postnatal outcomes among Black preterm infants.

BACKGROUND: Structural racism contributes to racial disparities in adverse perinatal outcomes. We sought to determine if structural racism is associated with adverse outcomes among Black preterm infants postnatally. METHODS: Observational cohort study of 13,321 Black birthing people who delivered preterm (gestational age 22-36 weeks) in California in 2011-2017 using a statewide birth cohort database and the American Community Survey. Racial and income segregation was quantified by the Index of Concentration at the Extremes (ICE) scores. Multivariable generalized estimating equations regression models were fit to test the association between ICE scores and adverse postnatal outcomes: frequent acute care visits, readmissions, and pre- and post-discharge death, adjusting for infant and birthing person characteristics and social factors. RESULTS: Black birthing people who delivered preterm in the least privileged ICE tertiles were more likely to have infants who experienced frequent acute care visits (crude risk ratio [cRR] 1.3 95% CI 1.2-1.4), readmissions (cRR 1.1 95% CI 1.0-1.2), and post-discharge death (cRR 1.9 95% CI 1.2-3.1) in their first year compared to those in the privileged tertile. Results did not differ significantly after adjusting for infant or birthing person characteristics. CONCLUSION: Structural racism contributes to adverse outcomes for Black preterm infants after hospital discharge. IMPACT STATEMENT: Structural racism, measured by racial and income segregation, was associated with adverse postnatal outcomes among Black preterm infants including frequent acute care visits, rehospitalizations, and death after hospital discharge. This study extends our understanding of the impact of structural racism on the health of Black preterm infants beyond the perinatal period and provides reinforcement to the concept of structural racism contributing to racial disparities in poor postnatal outcomes for preterm infants. Identifying structural racism as a primary cause of racial disparities in the postnatal period is necessary to prioritize and implement appropriate structural interventions to improve outcomes.

Agency in Contraceptive Decision-Making in Patient Care: a Psychometric Measure.

BACKGROUND: Patient agency in contraceptive decision-making is an essential component of reproductive autonomy. OBJECTIVE: We aimed to develop a psychometrically robust measure of patient contraceptive agency in the clinic visit, as a measure does not yet exist. DESIGN: For scale development, we generated and field tested 54 questionnaire items, grounded in qualitative research. We used item response theory-based methods to select and evaluate scale items for psychometric performance. We iteratively examined model fit, dimensionality, internal consistency, internal structure validity, and differential item functioning to arrive at a final scale. PARTICIPANTS: A racially/ethnically diverse sample of 338 individuals, aged 15-34 years, receiving contraceptive care across nine California clinics in 2019-2020. MAIN MEASURES: Contraceptive Agency Scale (CAS) of patient agency in preventive care. KEY RESULTS: Participants were 20.5 mean years, with 36% identifying as Latinx, 26% White, 20% Black, 10% Asian/Native Hawaiian/Pacific Islander. Scale items covered the domains of freedom from coercion, non-judgmental care, and active decision-making, and loaded on to a single factor, with a Cronbach's α of 0.80. Item responses fit a unidimensional partial credit item response model (weighted mean square statistic within 0.75-1.33 for each item), met criteria for internal structure validity, and showed no meaningful differential item functioning. Most participants expressed high agency in their contraceptive visit (mean score 9.6 out of 14). One-fifth, however, experienced low agency or coercion, with the provider wanting them to use a specific method or to make decisions for them. Agency scores were lowest among Asian/Native Hawaiian/Pacific Islander participants (adjusted coefficient: -1.5 [-2.9, -0.1] vs. White) and among those whose mothers had less than a high school education (adjusted coefficient; -2.1 [-3.3, -0.8] vs. college degree or more). CONCLUSIONS: The Contraceptive Agency Scale can be used in research and clinical care to reinforce non-coercive service provision as a standard of care.

Clinicians' Perspectives on Racism and Black Women's Maternal Health.

Objective: The objective of this study was to explore clinician perceptions of how racism affects Black women's pregnancy experiences, perinatal care, and birth outcomes. Materials and Methods: We conducted 25 semi-structured interviews with perinatal care clinicians practicing in the San Francisco Bay Area (January to March 2019) who serve racially diverse women. Participants were primarily recruited through "Dear Perinatal Care Provider" email correspondences sent through department listservs. Culturally concordant, qualitatively trained research assistants conducted all interviews in person. The interviews ranged from 30 to 60 minutes and were audio-recorded and professionally transcribed verbatim. We used the constant comparative method consistent with grounded theory to analyze data. Results: Most participants were obstetrician/gynecologists (n = 11, 44%) or certified nurse midwives (n = 8, 32%), had worked in their current role for 1 to 5 years (n = 10, 40%), and identified as white (n = 16, 64%). Three themes emerged from the interviews: provision of inequitable care (e.g., I had a woman who had a massive complication during her labor course and felt like she wasn't being treated seriously); surveillance of Black women and families (e.g., A urine tox screen on the Black baby even though it was not indicated, and they didn't do it on the white baby when, in fact, it was indicated); and structural care issues (e.g., the history of medical racial experimentation). Conclusion: Clinicians' views about how racism is currently operating and negatively impacting Black women's care experiences, health outcomes, and well-being in medical institutions will be used to develop a racial equity training for perinatal care clinicians in collaboration with Black women and clinicians.

Risk of early birth by body mass index in a propensity score-matched sample: A retrospective cohort study.

OBJECTIVE: Evaluate the risk of preterm (<37 weeks) or early term birth (37 or 38 weeks) by body mass index (BMI) in a propensity score-matched sample. DESIGN: Retrospective cohort analysis. SETTING: California, USA. POPULATION: Singleton live births from 2011-2017. METHODS: Propensity scores were calculated for BMI groups using maternal factors. A referent sample of women with a BMI between 18.5 and <25.0 kg/m2 was selected using exact propensity score matching. Risk ratios for preterm and early term birth were calculated. MAIN OUTCOME MEASURES: Early birth. RESULTS: Women with a BMI <18.5 kg/m2 were at elevated risk of birth of 28-31 weeks (relative risk [RR] 1.2, 95% CI 1.1-1.4), 32-36 weeks (RR 1.3, 95% CI 1.2-1.3), and 37 or 38 weeks (RR 1.1, 95% CI 1.1-1.1). Women with BMI ≥25.0 kg/m2 were at 1.2-1.4-times higher risk of a birth <28 weeks and were at reduced risk of a birth between 32 and 36 weeks (RR 0.8-0.9) and birth during the 37th or 38th week (RR 0.9). CONCLUSION: Women with a BMI <18.5 kg/m2 were at elevated risk of a preterm or early term birth. Women with BMI ≥25.0 kg/m2 were at elevated risk of a birth <28 weeks. Propensity score-matched women with BMI ≥30.0 kg/m2 were at decreased risk of a spontaneous preterm birth with intact membranes between 32 and 36 weeks, supporting the complexity of BMI as a risk factor for preterm birth. TWEETABLE ABSTRACT: Propensity score-matched women with BMI ≥30 kg/m2 were at decreased risk of a late spontaneous preterm birth.

The Index of Concentration at the Extremes (ICE) and Pregnancy-Associated Mortality in Louisiana, 2016-2017.

OBJECTIVES: Social and contextual factors underlying the continually disproportionate and burdensome risk of adverse health outcomes experienced by Black women in the US are underexplored in the literature. The aim of this study was to use an index based on area-level population distributions of race and income to predict risk of death during pregnancy and up to 1 year postpartum among women in Louisiana. METHODS: Using vital records data provided by the Louisiana Department of Health 2016-2017 (n = 125,537), a modified Poisson model was fit with generalized estimating equations to examine the risk of pregnancy-associated death associated with census tract-level values of the Index of Concentration at the Extremes (ICE)-grouped by tertile-while adjusting for both individual and tract-level confounders. RESULTS: Analyses resulted in an estimated 1.73 (95% CI 1.02-2.93) times increased risk for pregnancy-associated death for those in areas which were characterized by concentrated deprivation (high proportions of Black and low-income residents) relative to those in areas of concentrated privilege (high proportions of white and high-income residents), independent of other factors. CONCLUSIONS FOR PRACTICE: In addition to continuing to consider the deeply entrenched racism and economic inequality that shape the experience of pregnancy-associated death, we must also consider their synergistic effect on access to resources, maternal population health, and health inequities.

Maternal nativity and risk of adverse perinatal outcomes among Black women residing in California, 2011-2017.

OBJECTIVE: Examine the risk of adverse perinatal outcomes among the United States (US)-born and foreign-born Black women in California. STUDY DESIGN: The study comprised all singleton live births to Black women in California between 2011 and 2017. We defined maternal nativity as US-born or foreign-born. Using Poisson regression, we computed risk ratios (RR) and 95% confidence intervals (CI) for three adverse perinatal outcomes: preterm birth, small for gestational age deliveries, and infant mortality. RESULTS: Rates of adverse perinatal outcomes were significantly higher among US-born Black women. In adjusted models, US-born Black women experienced an increased risk of preterm birth (RR 1.51, 95% CI 1.39, 1.65) and small for gestational age deliveries (RR 1.52, 95% CI 1.41, 1.64), compared to foreign-born Black women. CONCLUSIONS: Future studies should consider experiences of racism across the life course when exploring heterogeneity in the risk of adverse perinatal outcomes by nativity among Black women in the US.

The association between preterm birth and postpartum mental healthcare utilization among California birthing people.

BACKGROUND: While mental health conditions such as postpartum depression are common, little is known about how mental healthcare utilization varies after term versus preterm delivery. OBJECTIVE: This study aimed to determine whether preterm birth is associated with postpartum inpatient and emergency mental healthcare utilization. STUDY DESIGN: The study sample was obtained from a database of live-born neonates delivered in California between the years of 2011 and 2017. The sample included all people giving birth to singleton infants between the gestational age of 20 and 44 weeks. Preterm birth was defined as <37 weeks' gestation. Emergency department visits and hospitalizations with a mental health diagnosis within 1 year after birth were identified using International Classification of Diseases codes. Logistic regression was used to compare relative risks of healthcare utilization among people giving birth to preterm infants vs term infants, adjusting for the following covariates: age, race or ethnicity, parity, previous preterm birth, body mass index, tobacco use, alcohol or drug use, hypertension, diabetes mellitus, adequacy of prenatal care, education, insurance payer, and the presence of a mental health diagnosis before birth. Results were then stratified by mental health diagnosis before birth to determine whether associations varied based on mental health history. RESULTS: Of our sample of 3,067,069 births, 6.7% were preterm. In fully adjusted models, compared with people giving birth to term infants, people giving birth to preterm infants had a 1.5 times (relative risk; 95% confidence interval, 1.4-1.7) and 1.3 times (relative risk; 95% confidence interval, 1.2-1.4) increased risk of being hospitalized with a mental health diagnosis within 3 months and 1 year after delivery, respectively. People giving birth to preterm infants also had 1.4 times (95% confidence interval, 1.3-1.5) and 1.3 times (95% confidence interval, 1.2-1.4) increased risk of visiting the emergency department for a mental health diagnosis within 3 months and 1 year after birth, respectively. Stratifying by preexisting mental health diagnosis, preterm birth was associated with an elevated risk of mental healthcare utilization for people with and without a previous mental health diagnosis. CONCLUSION: We found that preterm birth is an independent risk factor for postpartum mental healthcare utilization. Our findings suggest that screening for and providing mental health resources to birthing people after delivery are crucial, particularly among people giving birth to preterm infants, regardless of mental health history.

Occurrence of fatal police violence during pregnancy and hazard of preterm birth in California.

BACKGROUND: Exposure to fatal police violence may play a role in population-level inequities in risk for preterm delivery. OBJECTIVE: To evaluate whether exposure to fatal police violence during pregnancy affects the hazard of preterm delivery and whether associations differ by race/ethnicity and fetal sex. METHODS: We leveraged temporal variation in incidents of fatal police violence within census tracts to assess whether occurrence of fatal police violence in a person's tract during pregnancy was associated with increased hazard of extremely (20-27 weeks), early (28-31 weeks), moderate (32-33 weeks), and late (32-36 weeks) preterm delivery in California from 2007 to 2015. We used both death records and the Fatal Encounters database to identify incidents of fatal police violence. We estimated hazard ratios (HR) using time-varying Cox proportional hazard models stratified by census tract, controlling for age, race/ethnicity, educational attainment, health insurance type, parity, and the year and season of conception. We further stratified by race/ethnicity and infant sex to evaluate whether there were differential effects by these characteristics. RESULTS: Exposure to an incident of fatal police violence was associated with a small increase in the hazard of late preterm birth using both the death records (N = 376,029; hazard ratio [HR] 1.05, 95% confidence interval [CI] 1.00, 1.10) and the Fatal Encounters data (N = 938,814; HR 1.03, 95% CI 1.00, 1.06). We also observed an association for moderate preterm birth in the Fatal Encounters data (HR 1.06, 95% CI 0.98, 1.15). We did not observe associations for early or extremely preterm birth in either data source. Larger relative hazards of moderate (HR 1.25, 95% CI 0.93, 1.68) and late preterm delivery (HR 1.18, 95% CI 1.05, 1.33) were observed among Black birth parents with female births in the Fatal Encounters data. CONCLUSIONS: Preventing police use of lethal force may reduce preterm delivery in communities where such violence occurs.

Black Women's Perspectives on Structural Racism across the Reproductive Lifespan: A Conceptual Framework for Measurement Development.

BACKGROUND: Exposures to structural racism has been identified as one of the leading risk factors for adverse maternal and infant health outcomes among Black women; yet current measures of structural racism do not fully account for inequities seen in adverse maternal and infant health outcomes between Black and white women and infants. In response, the purpose of this study was to conceptualize structural racism from the perspectives of Black women across the reproductive lifespan and its potential impact on adverse maternal and infant health outcomes. METHODS: We conducted a series of focus groups with 32 Black women across the reproductive lifespan (5 preconception, 13 pregnant, and 14 postpartum). Study criteria including self-identifying as Black, residing in Oakland or Fresno, California and representing one of three reproductive life tracks (preconception, pregnant, postpartum). We consulted with study participants and an expert advisory board to validate emergent domains of structural racism. RESULTS: Nine domains of structural racism emerged from a ground theory constant comparative analysis: Negative Societal Views; Housing; Medical Care; Law Enforcement; Hidden Resources; Employment; Education, Community Infrastructure; and Policing Black Families. CONCLUSIONS FOR PRACTICE: Findings from this study suggest that there is an interplay among structural racism, and social and structural determinants of health which has negative impacts on Black women's sexual and reproductive health. Furthermore, findings from this study can be used to develop more comprehensive medical assessments and policies to address structural racism experienced by Black women across the reproductive lifespan.

Racial and ethnic disparities in outcomes through 1 year of life in infants born prematurely: a population based study in California.

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.

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.

First-year college students' alcohol and hookup behaviours: sexual scripting and implications for sexual health promotion.

This study used a sexual scripting framework to analyse data from the Online College Social Life Survey to examine the role of individual, (e.g. gender, race and alcohol use), relational (partner type, condom use behaviours), and contextual factors (sex ratios and fraternity/sorority affiliation) influencing 4,292 first-year college students' hookup experiences. Results suggest that hookups are relatively "safe", with the the majority involving non-penetrative sexual behaviour, condom use, and familiar partners. However, alcohol use affected hookup behaviours and lower levels of condom use were associated with heavy alcohol use, even with less well known partners. Findings point to the importance of interventions that reinforce first-year students' positive behaviours and present them with protective behavioural strategies to use in the context of alcohol, and with repeat or well-known partners to reduce risk and have enjoyable, consensual sexual experiences.

Risk and Protective Factors for Preterm Birth Among Black Women in Oakland, California.

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.

Infant Outcomes Following Maternal Infection With Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2): First Report From the Pregnancy Coronavirus Outcomes Registry (PRIORITY) Study.

Infant outcomes after maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are not well described. In a prospective US registry of 263 infants, maternal SARS-CoV-2 status was not associated with birth weight, difficulty breathing, apnea, or upper or lower respiratory infection through 8 weeks of age.

Preterm birth and nativity among Black women with gestational diabetes in California, 2013-2017: a population-based retrospective cohort study.

BACKGROUND: Despite the disproportionate prevalence of gestational diabetes (GDM) and preterm birth (PTB) and their associated adverse perinatal outcomes among Black women, little is known about PTB among Black women with GDM. Specifically, the relationship between PTB by subtype (defined as indicated PTB and spontaneous PT labor) and severity, GDM, and nativity has not been well characterized. Here we examine the risk of PTB by severity (early < 34 weeks, late 34 to 36 weeks) and early term birth (37 to 38 weeks) by nativity among Black women with GDM in California. METHODS: This retrospective cohort study used linked birth certificate and hospital discharge data for 8609 of the 100,691 self-identifying non-Hispanic Black women with GDM who had a singleton live birth between 20 and 44 weeks gestation in California in 2013-2017. Adjusted odds ratios (aOR) and 95% confidence intervals (CIs) were examine risks for PTB, by severity and subtype, and early term birth using multivariate regression modeling. RESULTS: Approximately, 83.9% of Black women with GDM were US-born and 16.1% were foreign-born. The overall prevalence of early PTB, late PTB, and early term birth was 3.8, 9.5, and 29.9%, respectively. Excluding history of prior PTB, preeclampsia was the greatest overall risk factor for early PTB (cOR = 6.7, 95%, CI 5.3 to 8.3), late PTB (cOR = 4.3, 95%, CI 3.8 to 5.0), and early term birth (cOR = 1.8, 95%, CI 1.6 to 2.0). There was no significant difference in the prevalence of PTB by subtypes and nativity (p = 0.5963). Overall, 14.2% of US- compared to 8.9% of foreign-born women had a PTB (early PTB: aOR = 0.56, 95%, CI 0.38 to 0.82; late PTB: aOR = 0.57, 95%, CI 0.45 to 0.73; early term birth: aOR = 0.67, 95%, CI 0.58 to 0.77). CONCLUSIONS: Foreign-born status remained protective of PTB, irrespective of severity and subtype. Preeclampsia, PTB, and GDM share pathophysiologic mechanisms suggesting a need to better understand differences in perinatal stress, chronic disease, and vascular dysfunction based on nativity in future epidemiologic studies and health services research.

Clinical Presentation of Coronavirus Disease 2019 (COVID-19) in Pregnant and Recently Pregnant People.

OBJECTIVE: To describe the clinical presentation, symptomology, and disease course of coronavirus disease 2019 (COVID-19) in pregnancy. METHODS: The PRIORITY (Pregnancy CoRonavIrus Outcomes RegIsTrY) study is an ongoing nationwide prospective cohort study of people in the United States who are pregnant or up to 6 weeks postpregnancy with known or suspected severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We analyzed the clinical presentation and disease course of COVID-19 in participants who tested positive for SARS-CoV-2 infection and reported symptoms at the time of testing. RESULTS: Of 991 participants enrolled from March 22, 2020, until July 10, 2020, 736 had symptoms of COVID-19 at the time of testing; 594 tested positive for SARS-CoV-2 infection and 142 tested negative in this symptomatic group. Mean age was 31.3 years (SD 5.1), and 37% will nulliparous. Ninety-five percent were outpatients. Participants who tested positive for SARS-CoV-2-infection were a geographically diverse cohort: 34% from the Northeast, 25% from the West, 21% from the South, and 18% from the Midwest. Thirty-one percent of study participants were Latina, and 9% were Black. The average gestational age at enrollment was 24.1 weeks, and 13% of participants were enrolled after pregnancy. The most prevalent first symptoms in the cohort of patients who tested positive for SARS-CoV-2 infection were cough (20%), sore throat (16%), body aches (12%), and fever (12%). Median time to symptom resolution was 37 days (95% CI 35-39). One quarter (25%) of participants who tested positive for SARS-CoV-2 infection had persistent symptoms 8 or more weeks after symptom onset. CONCLUSION: COVID-19 has a prolonged and nonspecific disease course during pregnancy and in the 6 weeks after pregnancy. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT04323839.
