RESUMEN
BACKGROUND: Improving perinatal mental health and care experiences and preventing adverse maternal and infant outcomes are essential prenatal care components, yet existing services often miss the mark, particularly for low-income populations. An enhanced group prenatal care program, "Glow! Group Prenatal Care and Support," was developed in California's Central Valley in response to poor perinatal mental health, disrespectful care experiences, and high rates of adverse birth outcomes among families with low incomes. METHODS: Engaging Mothers & Babies; Reimagining Antenatal Care for Everyone (EMBRACE) is a pragmatic, two-arm, randomized, comparative-effectiveness study designed to assess depression (primary outcome), the experience of care (secondary outcome), and preterm birth (exploratory outcome) among Medi-Cal (California's Medicaid program)-eligible pregnant and birthing people, comparing those assigned to Glow! Group Prenatal Care and Support (Glow/GC) with those assigned to enhanced, individual prenatal care through the California Department of Public Health's Comprehensive Perinatal Services Program (CPSP/IC). Participating clinical practices offer the two comparators, alternating between comparators every 6 weeks, with the starting comparator randomized at the practice level. Participant-reported outcomes are assessed through interviewer-administered surveys at study entry, during the participant's third trimester, and at 3 months postpartum; preterm birth and other clinical outcomes are abstracted from labor and delivery records. Patient care experiences are further assessed in qualitative interviews. The protocol complies with the Standard Protocol Items for Randomized Trials. CONCLUSIONS: This comparative-effectiveness study will be used to determine which of two forms of enhanced prenatal care is more effective, informing future decisions regarding their use. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04154423.

BACKGROUND: African-born women have a lower risk of preterm birth and small for gestational age (SGA) birth compared with United States-born Black women, however variation by country of origin is overlooked. Additionally, the extent that nativity disparities in adverse perinatal outcomes to Black women are explained by individual-level factors remains unclear. METHODS: We conducted a population-based study of nonanomalous singleton live births to United States- and African-born Black women in California from 2011 to 2020 (n = 194,320). We used age-adjusted Poisson regression models to estimate the risk of preterm birth and SGA and reported risk ratios (RR) and 95% confidence intervals (CI). Decomposition using Monte Carlo integration of the g-formula computed the percentage of disparities in adverse outcomes between United States- and African-born women explained by individual-level factors. RESULTS: Eritrean women (RR = 0.4; 95% CI = 0.3, 0.5) had the largest differences in risk of preterm birth and Cameroonian women (RR = 0.5; 95% CI = 0.3, 0.6) in SGA birth, compared with United States-born Black women. Ghanaian women had smaller differences in risk of preterm birth (RR = 0.8; 95% CI = 0.7, 1.0) and SGA (RR = 0.9; 95% CI = 0.8, 1.1) compared with United States-born women. Overall, we estimate that absolute differences in socio-demographic and clinical factors contributed to 32% of nativity-based disparities in the risk of preterm birth and 26% of disparities in SGA. CONCLUSIONS: We observed heterogeneity in risk of adverse perinatal outcomes for African- compared with United States-born Black women, suggesting that nativity disparities in adverse perinatal outcomes were not fully explained by differences in individual-level factors.

INTRODUCTION: Even in the small number of U.S. states with paid parental leave (PPL) programs, studies have found awareness of PPL remains low and unevenly distributed among parents. Moreover, little is known about whether parents with perinatal health complications have unmet needs in obtaining information about and support for accessing parental leave during that time. This study aims to address this research gap. Given the strong evidence linking paid leave with improvements in maternal and infant health, it is critical to evaluate access among vulnerable populations. METHODS: We used a multiple methods approach, including a subset of the 2016-2017 Bay Area Parental Leave Survey of Mothers (analytic sample = 1,007) and interview data from mothers who stayed at a neonatal intensive care unit in 2019 (n = 7). All participants resided at that time in California, a state that offers PPL. The independent variable for the survey analysis was a composite measure of perinatal complications, quantified as binary with a value of 1 if respondents reported experiencing any of the four complications: poor maternal mental health during or after pregnancy, premature birth, or poor infant health. Dependent variables for the survey analysis measured lack of support or information for accessing PPL. We used linear probability models to assess the relationship between perinatal complications and PPL support. Thematic analysis was conducted with the interview data to understand how perinatal complications shape the process of accessing PPL. RESULTS: Survey results revealed that parents with perinatal complications had a lower understanding of PPL benefits and low overall support for accessing leave, including from employers, compared with parents without perinatal complications. From interviews, we learned that perinatal complications present unique challenges to parents navigating PPL. There were multiple entities involved in managing leave and providing information, such as the benefits coordinator and employers. Supervisors were reported as providers of critical emotional and financial support. CONCLUSIONS: Taken together, the findings from surveys and interviews suggest that health care and human resources personnel should be better equipped to provide information and support, particularly to those who experience perinatal complications and might struggle to complete paperwork while facing health challenges.

BACKGROUND: Black women in the United States (US) have the highest risk of preterm birth (PTB) and small for gestational age (SGA) births, compared to women of other racial groups. Among Black women, there are disparities by nativity whereby foreign-born women have a lower risk of PTB and SGA compared to US-born women. Differential exposure to racism may confer nativity-based differences in adverse perinatal outcomes between US- and foreign-born Black women. This remains unexplored among US- and African-born women in California. OBJECTIVES: Evaluate the relationship between structural racism, nativity, PTB and SGA among US- and African-born Black women in California. METHODS: We conducted a population-based study of singleton births to US- and African-born Black women in California from 2011 to 2017 (n = 131,424). We examined the risk of PTB and SGA by nativity and neighbourhoods with differing levels of structural racism, as measured by the Index of Concentration at the Extremes. We fit crude and age-adjusted Poisson regression models, estimated using generalized estimating equations, with risk ratios (RR) and 95% confidence intervals (CI) as the effect measure. RESULTS: The proportions of PTB and SGA were 9.7% and 14.5%, respectively, for US-born women, while 5.6% and 8.3% for African-born women. US-born women (n = 24,782; 20.8%) were more likely to live in neighbourhoods with high structural racism compared to African-born women (n = 1474; 11.6%). Structural racism was associated with an elevated risk of PTB (RR 1.19, 95% CI 1.12, 1.26) and SGA (RR 1.19, 95% CI 1.13, 1.25) for all Black women, however, there was heterogeneity by nativity, with US-born women experiencing a higher magnitude of effect than African-born women. CONCLUSIONS: Among Black women in California, exposure to structural racism and the impacts of structural racism on the risk of PTB and SGA varied by nativity.

BACKGROUND: The largest poverty alleviation program in the US is the earned income tax credit (EITC), providing $60 billion to over 25 million families annually. While research has shown positive impacts of EITC receipt in pregnancy, there is little evidence on whether the timing of receipt may lead to differences in pregnancy outcomes. We used a quasi-experimental difference-in-differences design, taking advantage of EITC tax disbursement each spring to examine whether trimester of receipt was associated with perinatal outcomes. METHODS: We conducted a difference-in-differences analysis of California linked birth certificate and hospital discharge records. The sample was drawn from the linked CA birth certificate and discharge records from 2007-2012 (N = 2,740,707). To predict eligibility, we created a probabilistic algorithm in the Panel Study of Income Dynamics and applied it to the CA data. Primary outcome measures included preterm birth, small-for-gestational age (SGA), gestational diabetes, and gestational hypertension/preeclampsia. RESULTS: Eligibility for EITC receipt during the third trimester was associated with a lower risk of preterm birth compared with preconception. Eligibility for receipt in the preconception period resulted in improved gestational hypertension and SGA. CONCLUSION: This analysis offers a novel method to impute EITC eligibility using a probabilistic algorithm in a data set with richer sociodemographic information relative to the clinical and administrative data sets from which outcomes are drawn. These results could be used to determine the optimal intervention time point for future income supplementation policies. Future work should examine frequent income supplementation such as the minimum wage or basic income programs.

Objectives. To estimate changes in national breastfeeding trends immediately before and after COVID-19ârelated workplace closures in early 2020. Methods. The implementation of shelter-in-place policies in early 2020, when 90% of people in the United States were urged to remain at home, represents a unique natural experiment to assess the pent-up demand for breastfeeding among US women that may be stymied by the lack of a national paid leave policy. We used the 2017-2020 Pregnancy Risk Assessment Monitoring System (n = 118 139) to estimate changes in breastfeeding practices for births occurring before and after shelter-in-place policies were implemented in the United States. We did this in the overall sample and by racial/ethnic and income subgroups. Results. There was no change in breastfeeding initiation and a 17.5% increase in breastfeeding duration after shelter-in-place, with lingering effects through late 2020. High-income and White women demonstrated the largest gains. Conclusions. The United States ranks worse than similar countries when it comes to breastfeeding initiation and duration. This study suggests that this is partly attributable to inadequate access to postpartum paid leave. This study also demonstrates inequities introduced by patterns of remote work during the 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.

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.

INTRODUCTION: One in 5 pregnant individuals report consuming sugar-sweetened beverages at least once per day. Excess sugar consumption during pregnancy is associated with several perinatal complications. As sugar-sweetened beverage taxes become increasingly common public health measures to reduce sugar-sweetened beverage consumption, evidence of the downstream effects of sugar-sweetened beverage taxes on perinatal health remains limited. METHODS: This longitudinal retrospective study examines whether sugar-sweetened beverage taxes in 5 U.S. cities were associated with decreased risk of perinatal complications, leveraging 2013-2019 U.S. national birth certificate data and a quasi-experimental difference-in-differences approach to estimate changes in perinatal outcomes. Analysis occurred from April 2021 through January 2023. RESULTS: The sample included 5,324,548 pregnant individuals and their live singleton births in the U.S. from 2013 through 2019. Sugar-sweetened beverage taxes were associated with a 41.4% decreased risk of gestational diabetes mellitus (-2.2 percentage points; 95% CI= -4.2, -0.2), a -7.9% reduction in weight-gain-for-gestational-age z-score (-0.2 standard deviations; 95% CI= -0.3, -0.01), and decreased risk of infants born small for gestational age (-4.3 percentage points; 95% CI= -6.5, -2.1). There were heterogeneous effects across subgroups, particularly for weight-gain-for-gestational-age z-score. CONCLUSIONS: Sugar-sweetened beverage taxes levied in five U.S. cities were associated with improvements in perinatal health. Sugar-sweetened beverage taxes may be an effective policy instrument for improving health during pregnancy, a critical window during which short-term dietary exposures can have lifelong consequences for the birthing person and child.

Since 2017, San Francisco's Paid Parental Leave Ordinance (PPLO) has allowed parents who work for private-sector employers to take 6 weeks of fully paid postnatal parental leave. Previous studies have linked paid parental leave with health improvements for birthing people and babies, although evidence for birth outcomes is limited. We hypothesized that the PPLO may have improved birth outcomes via reduced stress during pregnancy due to anticipation of increased financial security and postnatal leave. We used linked California birth certificate and hospital discharge records from January 2013 to December 2018 (n = 1,420,781). We used quasi-experimental difference-in-difference (DD) models to compare outcomes among SF births before and after PPLO to outcomes among births in control counties. Births from January 2017 through December 2018 among working San Francisco (SF) people were considered "exposed" to PPLO; births during this time among working people outside of SF, as well as all births before 2017, served as controls. We conducted subgroup analyses by race/ethnicity, education and Medicaid coverage at delivery. Overall analyses adjusting for covariates and indicators for time and seasonality indicated no association between PPLO and birth outcomes. Our results indicate that PPLO may not have affected the birth outcomes we examined among marginalized groups who, due to structural racism, are at heightened risk of poor outcomes. We speculate that this result is due to the PPLO's design and focus on postnatal leave. Future work should examine the policy's effects on other outcomes.

Recent evidence on perceived stress during the COVID-19 pandemic shows that birthing people experienced stress from pandemic-related stressors. While psychosocial stress is a significant predictor of adverse birth outcomes, social support can reduce stress levels during pregnancy. This study examined social support moderation of relationships between COVID-19-related stressors and perceived stress during pregnancy. The analysis included data from publicly insured pregnant participants who were enrolled in a randomized control trial of two enhanced prenatal care models in Fresno, California, and completed a third-trimester questionnaire between April and August 2020 (n = 77). Multivariate linear regression was used to estimate the associations between perceived stress and COVID-19-related stressors and social support moderation. COVID-19-related stressors related to childcare and tension at home remained significantly associated with perceived stress adjusting for sociodemographic characteristics and other COVID-19-related stressors. Social support moderated the relationship between perceived stress and loss of childcare (ß = 2.4, 95 percent CI = 0.5-4.3, p = .014). Overall, social support moderated the association between COVID-19 stressors and perceived stress. While social support is commonly conceptualized as protective, the finding of greater stress around childcare among individuals reporting greater social support suggests complexity for leveraging these support networks during the pandemic.

BACKGROUND: The Deferred Action for Childhood Arrivals (DACA) program provides temporary relief from deportation and work permits for previously undocumented immigrants who arrived as children. DACA faced direct threats under the Trump administration. There is select evidence of the short-term impacts of DACA on population health, including on birth outcomes, but limited understanding of the long-term impacts. METHODS: We evaluated the association between DACA program and birth outcomes using California birth certificate data (2009-2018) and a difference-in-differences approach to compare post-DACA birth outcomes for likely DACA-eligible mothers to birth outcomes for demographically similar DACA-ineligible mothers. We also separately compared birth outcomes by DACA eligibility status in the first 3 years after DACA passage (2012-2015) and in the subsequent 3 years (2015-2018) - a period characterized by direct threats to the DACA program - as compared to outcomes in the years prior to DACA passage. RESULTS: In the 7 years after its passage, DACA was associated with a lower risk of small-for-gestational age (- 0.018, 95% CI: - 0.035, - 0.002) and greater birthweight (45.8 g, 95% CI: 11.9, 79.7) for births to Mexican-origin individuals that were billed to Medicaid. Estimates were consistent but of smaller magnitude for other subgroups. Associations between DACA and birth outcomes were attenuated to the null in the period that began with the announcement of the Trump U.S. Presidential campaign (2015-2018), although confidence intervals overlapped with estimates from the immediate post-DACA period. CONCLUSIONS: These findings suggest weak to modest initial benefits of DACA for select birthweight outcomes during the period immediately following DACA passage for Mexican-born individuals whose births were billed to Medicaid; any benefits were subsequently attenuated to the null. The benefits of DACA for population health may not have been sufficient to counteract the impacts of threats to the program's future and heightened immigration enforcement occurring in parallel over time.

OBJECTIVE: Hypertension during pregnancy can adversely affect maternal and fetal health. This study assessed whether diagnosis of leukemia or lymphoma prior to pregnancy is associated with hypertensive disorders of pregnancy including gestational hypertension, preeclampsia and eclampsia. STUDY DESIGN: A cross-sectional study used two statewide population-based datasets that linked birth certificates with sources of maternal medical history: hospital discharges in California and Surveillance, Epidemiology, and End Results (SEER) cancer registry data in Iowa. Birth years included 2007-2012 in California and 1989-2018 in Iowa. MAIN OUTCOME MEASURES: Primary outcome measure was hypertension in pregnancy measured from combined birth certificate and hospital diagnoses in California (for gestational hypertension, preeclampsia, or eclampsia) and birth certificate information (gestational hypertension or eclampsia) in Iowa. RESULTS: After adjusting for maternal age, race, education, smoking, and plurality, those with a history of leukemia/lymphoma were at increased risk of hypertensive disorders of pregnancy in Iowa (odds ratio (OR) = 1.86; 95% CI 1.07-3.23), but not in California (OR = 1.12; 95% CI 0.87-1.43). In sensitivity analysis restricting to more severe forms of hypertension in pregnancy (preeclampsia and eclampsia) in the California cohort, the effect estimate increased (OR = 1.29; 95% CI 0.96-1.74). CONCLUSION: In a population-based linked cancer registry-birth certificate study, an increased risk of hypertensive disorders of pregnancy was observed among leukemia or lymphoma survivors. Findings were consistent but non-significant in a second, more ethnically diverse study population with less precise cancer history data. Improved monitoring and surveillance may be warranted for leukemia or lymphoma survivors throughout their pregnancies.

INTRODUCTION: Previous studies that used traditional multivariable and sibling matched analyses to investigate interpregnancy interval (IPI) and birth outcomes have reached mixed conclusions about a minimum recommended IPI, raising concerns about confounding. Our objective was to isolate the contribution of interpregnancy interval to the risk for adverse birth outcomes using propensity score matching. METHODS: For this retrospective cohort study, data were drawn from a California Department of Health Care Access and Information database with linked vital records and hospital discharge records (2007-2012). We compared short IPIs of < 6, 6-11, and 12-17 months to a referent IPI of 18-23 months using 1:1 exact propensity score matching on 13 maternal sociodemographic and clinical factors. We used logistic regression to calculate the odds of preterm birth, early-term birth, and small for gestational age (SGA). RESULTS: Of 144,733 women, 73.6% had IPIs < 18 months, 5.5% delivered preterm, 27.0% delivered early-term, and 6.0% had SGA infants. In the propensity matched sample (n = 83,788), odds of preterm birth were increased among women with IPI < 6 and 6-11 months (OR 1.89, 95% CI 1.71-2.0; OR 1.22, 95% CI 1.13-1.31, respectively) and not with IPI 12-17 months (OR 1.01, 95% CI 0.94-1.09); a similar pattern emerged for early-term birth. The odds of SGA were slightly elevated only for intervals < 6 months (OR 1.10, 95% CI 1.00-1.20, p < .05). DISCUSSION: This study demonstrates a dose response association between short IPI and adverse birth outcomes, with no increased risk beyond 12 months. Findings suggest that longer IPI recommendations may be overly proscriptive.

BACKGROUND: Birthing people of color are more likely to deliver low birthweight and preterm infants, populations at significant risk of morbidity and mortality. Birthing people of color are also at higher risk for mental health conditions and emergency mental healthcare utilization postpartum. Although this group has been identified as high risk in these contexts, it is not known whether racial and ethnic disparities exist in mental healthcare utilization among birthing people who have delivered preterm. OBJECTIVE: We sought to determine if racial and ethnic disparities exist in postpartum mental healthcare-associated emergency department visits or hospitalizations for birthing people with preterm infants in a large and diverse population. STUDY DESIGN: This population-based historic cohort study used a sample of Californian live-born infants born between 2011 and 2017 with linked birth certificates and emergency department visit and hospital admission records from the California Statewide Health Planning and Development database. The sample was restricted to preterm infants (<37 weeks' gestation). Self-reported race and ethnicity groups included Hispanic, non-Hispanic Black, non-Hispanic Asian, non-Hispanic White, and non-Hispanic others. Mental health diagnoses were identified from the International Classification of Diseases Ninth and Tenth revision codes recorded in emergency department and hospital discharge records. Logistic regression analysis was used to estimate the association between mental health-related emergency department visits and rehospitalizations by race or ethnicity compared with non-Hispanic White birthing people and controlling for the following characteristics and health condition covariates: age, parity, previous preterm birth, body mass index, smoking, alcohol use, hypertension, diabetes, previous mental health diagnosis, and prenatal care. RESULTS: Of 204,539 birthing people who delivered preterm infants in California, 1982 visited the emergency department and 836 were hospitalized in the first year after preterm birth for a mental health-related illness. Black birthing people were more likely to have a mental health-related emergency department visit and hospitalization (risk ratio, 1.8; 95% confidence interval, 1.5-2.0 and risk ratio, 1.9; 95% confidence interval, 1.5-2.3, respectively) within the first postpartum year than White birthing people. Hispanic and Asian birthing people were less likely to have mental health-related emergency department visits (adjusted risk ratio, 0.7; 95% confidence interval, 0.7-0.8 and adjusted risk ratio, 0.2; 95% confidence interval, 0.2-0.3, respectively) and hospitalizations (adjusted risk ratio, 0.6; 95% confidence interval, 0.5-0.7 and adjusted risk ratio, 0.2; 95% confidence interval, 0.1-0.3, respectively). When controlling for birthing people with a previous mental health diagnosis and those without, the disparities remained the same. CONCLUSION: Racial and ethnic disparities exist in emergency mental healthcare escalation among birthing people who have delivered preterm infants. Our findings highlight a need for further investigation into disparate mental health conditions, exacerbations, access to care, and targeted hospital and legislative policies to prevent emergency mental healthcare escalation and reduce disparities.

OBJECTIVE: We examined whether the largest U.S. poverty alleviation program for families, the Earned Income Tax Credit (EITC), has different associations with birthweight among women of different racial backgrounds. DESIGN: We analyzed data from the 1985-2015 waves of the Panel Study of Income Dynamics, a longitudinal cohort study of U.S. families (N = 5,230 infants born to 3,672 women). The primary outcome was a continuous measure of birthweight, with secondary outcomes including low birthweight (LBW) and very LBW. Using rich sociodemographic data available in the Panel Study of Income Dynamics, we calculated the amount of EITC benefit for which women were eligible. We then examined the association of EITC benefit size with each outcome using multivariable regressions, examining the sample overall as well as racial subgroups (White, Black, or other). RESULTS: We found that larger EITC benefits were not associated with increased infant birthweight for the overall sample (18.37 g per $1,000 of EITC; 95% confidence interval [CI], -2.62 to 33.36). There was an increase in birthweight for Black women (40.17 g; 95% CI: 7.32 to 73.02), but not for White women (-1.86 g; 95% CI, -33.33 to 29.60) or women of other races (-13.26 g; 95% CI, -75.90 to 49.38). There was no association between EITC benefit size and the probability of LBW or very LBW. Results were robust to alternative model specifications. CONCLUSIONS: Social policies to address poverty may be effective at decreasing racial disparities in birthweight. Future work should examine potential mechanisms and the benefits of improved health outcomes for children later in life.

Periviable infants (i.e., born before 26 complete weeks of gestation) represent fewer than .5% of births in the US but account for 40% of infant mortality and 20% of billed hospital obstetric costs. African American women contribute about 14% of live births in the US, but these include nearly a third of the country's periviable births. Consistent with theory and with periviable births among other race/ethnicity groups, males predominate among African American periviable births in stressed populations. We test the hypothesis that the disparity in periviable male births among African American and non-Hispanic white populations responds to the African American unemployment rate because that indicator not only traces, but also contributes to, the prevalence of stress in the population. We use time-series methods that control for autocorrelation including secular trends, seasonality, and the tendency to remain elevated or depressed after high or low values. The racial disparity in male periviable birth increases by 4.45% for each percentage point increase in the unemployment rate of African Americans above its expected value. We infer that unemployment-a population stressor over which our institutions exercise considerable control-affects the disparity between African American and non-Hispanic white periviable births in the US.

OBJECTIVE: Leukemia and lymphoma are top cancers affecting children, adolescents and young adults with high five-year survival rates. Late effects of these cancers are a concern in reproductive-age patients, including pregnancy outcomes such as preterm birth. Our study aimed to evaluate whether diagnosis of leukemia or lymphoma prior to pregnancy was associated with preterm birth (<37 weeks gestation). METHODS: We conducted a cross-sectional study using a population-based dataset from California with linked birth certificates to hospital discharge records and an Iowa-based sample that linked birth certificates to Surveillance, Epidemiology, and End Results (SEER) cancer registry data. Preterm birth was defined using birth certificates. We ascertained history of leukemia and lymphoma using discharge diagnosis data in California and SEER registry in Iowa. RESULTS: Prevalence of preterm birth in California and Iowa was 14.6% and 12.0%, respectively, in women with a history of leukemia/lymphoma compared to 7.8% and 8.2%, respectively, in women without a cancer history. After adjusting for maternal age, race, education, smoking, and plurality, Women with history of leukemia/lymphoma were at an increased risk of having a preterm birth in California (odds ratio (OR) 1.89; 95% confidence interval (CI) 1.56-2.28) and Iowa (OR 1.61; 95% CI 1.10-2.37) compared to those with no cancer history. CONCLUSION: In both California and Iowa, women with a history of leukemia or lymphoma were at increased risk for preterm birth. This suggests the importance of counseling with a history of leukemia/lymphoma prior to pregnancy and increased monitoring of women during pregnancy.

BACKGROUND: Preliminary studies suggest that the SARS-CoV-2 pandemic and associated social, economic and clinical disruptions have affected pregnancy decision-making and outcomes. Whilst a few US-based studies have examined regional changes in birth outcomes during the pandemic's first months, much remains unknown of how the pandemic impacted perinatal health indicators at the national-level throughout 2020, including during the 'second wave' of infections that occurred later in the year. OBJECTIVES: To describe changes in monthly rates of perinatal health indicators during the 2020 pandemic for the entire US. METHODS: For the years 2015 to 2020, we obtained national monthly rates (per 100 births) for four perinatal indicators: preterm (<37 weeks' gestation), early preterm (<34 weeks' gestation), late preterm (34-36 weeks' gestation) and caesarean delivery. We used an interrupted time-series approach to compare the outcomes observed after the pandemic began (March 2020) to those expected had the pandemic not occurred for March through December of 2020. RESULTS: Observed rates of preterm birth fell below expectation across several months of the 2020 pandemic. These declines were largest in magnitude in early and late 2020, with a 5%-6% relative difference between observed and expected occurring in March and November. For example, in March 2020, the observed preterm birth rate of 9.8 per 100 live births fell below the 95% prediction interval (PI) of the rate predicted from history, which was 10.5 preterm births per 100 live births (95% PI 10.2, 10.7). We detected no changes from expectation in the rate of caesarean deliveries. CONCLUSIONS: Our findings provide nationwide evidence of unexpected reductions in preterm delivery during the 2020 SARS-CoV-2 pandemic in the US. Observed declines below expectation were differed by both timing of delivery and birth month, suggesting that several mechanisms, which require further study, may explain these patterns.

Exposure to nitrogen dioxide (NO2), black carbon (BC), and ultrafine particles (UFPs) during pregnancy may increase the risk of preeclampsia, but previous studies have not assessed hyperlocalized differences in pollutant levels, which may cause exposure misclassification. We used data from Google Street View cars with mobile air monitors that repeatedly sampled NO2, BC, and UFPs every 30 m in Downtown and West Oakland neighborhoods during 2015-2017. Data were linked to electronic health records of pregnant women in the 2014-2016 Sutter Health population, who resided within 120 m of monitoring data (N = 1095), to identify preeclampsia cases. We used G-computation with log-binomial regression to estimate risk differences (RDs) associated with a hypothetical intervention reducing pollutant levels to the 25th percentile observed in our sample on preeclampsia risk, overall and stratified by race/ethnicity. Prevalence of preeclampsia was 6.8%. Median (interquartile range) levels of NO2, BC, and UFPs were 10.8 ppb (9.0, 13.0), 0.34 µg/m3 (0.27, 0.42), and 29.2 # × 103/cm3 (26.6, 32.6), respectively. Changes in the risk of preeclampsia achievable by limiting each pollutant to the 25th percentile were NO2 RD = -1.5 per 100 women (95% confidence interval (CI): -2.5, -0.5); BC RD = -1.0 (95% CI: -2.2, 0.02); and UFP RD = -0.5 (95% CI: -1.8, 0.7). Estimated effects were the largest for non-Latina Black mothers: NO2 RD = -2.8 (95% CI: -5.2, -0.3) and BC RD = -3.0 (95% CI: -6.4, 0.4).
