Disparities In Outcomes Research Articles

What about sex, race(ism), and social determinants of health in neonatal outcomes?

Neonatal outcomes encompass a range of outcome measures, including mortality rates, physical and mental health morbidities, and long-term neurodevelopmental statistics. These outcomes are influenced by non-modifiable factors, such as sex and race, and modifiable factors, such as social determinants of health and racism. There is a known bias toward worse outcomes for male infants in terms of preterm birth, low birth weight, and mortality, with several biological and physiological factors contributing to these sex-related differences. In relation to racial disparities, wherein race is a social construct, maternal and infant healthcare continues to lag behind for minority populations compared with the white population, despite advances in medical care. Infants born to Black women have higher infant mortality rates and lower birth weights than infants of white women. These differences can be largely attributed to social and environmental factors, rather than racial and ethnic differences. Furthermore, we emphasize the role of social determinants of health in neonatal outcomes. Factors such as economic stability, education access and quality, healthcare access and quality, the physical neighborhood environment, and the social and community context all contribute to these outcomes. Overall, this article highlights the complex interactions between sex, race(ism), and social determinants of health in neonatal outcomes. It underscores the need for a comprehensive understanding of these factors to improve maternal-neonatal care and reduce disparities in outcomes. Healthcare providers, policymakers, and communities need to work together to combat these complex issues and improve neonatal outcomes for all infants, while understanding the complex interplay between sex, racism, and/or social determinants of health.

Racial discrepancies in initial presentation and diagnosis of patients with endometrial cancer.

89 Background: Endometrial cancer incidence and mortality are increasing, particularly in Black patients who have more aggressive non-endometrioid subtypes. Racial disparities in mortality may be partially contributable to early clinical factors including recognition of symptoms, type of evaluation, and referral timing. We evaluated differences in factors related to symptom appraisal and delays in diagnosis by race and histology. Methods: In this retrospective cohort study, we included patients diagnosed with endometrial cancer from 01/01/2019 to 09/01/2023 at a single institution who were enrolled in the Discovery and Evaluation of Testing for Endometrial Cancer in Tampons (DETECT) study. Demographic characteristics and factors regarding initial presentation and workup were obtained from the electronic medical record. We evaluated patient-reported length and type of symptoms at initial presentation, diagnostic imaging type, and time from initial presentation to time of imaging, tissue sampling, and referral to gynecologic oncology. We assessed differences by race and histology (endometrioid vs. non-endometroid) using chi-square and Kruskal-Wallis tests and analysis of variance. Results: Of the 335 patients included in our analysis, 237 (70.7%) had endometrioid and 98 (29.3%) had non-endometrioid histology. Patients with endometrioid histology were significantly more likely to be younger, White, non-smokers, and have higher obesity levels by body mass index than those with non-endometrioid histology (p=<0.01). The length of symptoms at time of initial presentation was significantly longer in Black patients overall (p=0.01) and in Black patients with endometrioid histology compared to their White counterparts (p=0.04). A similar trend was seen in patients with non-endometrioid histology but was not statistically significant (p=0.15). There was no difference in type of symptoms reported. The type of imaging (p=0.005) differed significantly between endometrioid and non-endometrioid groups. White patients were more likely to have a transvaginal ultrasound performed at initial presentation (p=0.004). Black patients with endometrioid endometrial cancer were more likely to have a longer time period from initial presentation to referral to gynecologic oncology (p=0.04) despite having a shorter time between initial presentation and endometrial sampling (p=0.04). Conclusions: In our cohort, Black patients with endometrial cancer were more likely to have experienced symptoms for a longer time period prior to presentation, less likely to be evaluated with transvaginal ultrasound, and had a longer time period between initial presentation and referral to gynecologic oncology compared to White patients. Raising awareness and targeting these early steps in evaluation and detection of endometrial cancer may help decrease racial disparities in outcomes.

Assessing capacity for hereditary cancer risk assessment in metro Chicago.

307 Background: Since 2005, the United States Preventive Services Task Force (USPSTF) recommends that primary care (PC) clinicians identify and refer adults with a high-risk cancer family history to cancer genetic services (CGS), yet hereditary cancer risk assessment (HCRA) continues to be underutilized in PC. A population-based approach to HCRA in PC settings can expand access to cancer prevention and early detection to vulnerable populations and reduce disparities in cancer outcomes. The Chicago Cancer Screening and Testing Access Coalition (CCSTAC) is developing strategies to integrate HCRA in PC settings. We conducted an environmental scan to assess current capacity to deliver 1) HRCA in Federally Qualified Health Centers (FQHCs) and 2) follow-up CGS for high risk patients. Methods: In 2023, we administered two surveys to assess HCRA practices in Metro Chicago. We invited 22 FQHCs to complete a 21-item survey of current practices, readiness to implement, and barriers to HCRA. We also invited 21 CGS sites to complete a 25-item survey to understand staffing, utilization, referral patterns, and barriers to access. Surveys were administered electronically via Qualtrics. We conducted a descriptive analysis of survey data. Results: Twenty FQHCs (91%) completed the survey on HCRA in PC; 85% reported familiarity with USPSTF guidelines for HCRA. The majority (75%) reported no plans to implement HCRA. Clinic workflow, paucity of follow-up resources, cost, lack of provider knowledge, and absence of HCRA as a mandatory performance measure were cited as the most significant barriers to implementation. Genetic counselors (GCs) from 19 CGS hospital-based sites (90%) completed the survey on availability of genetic services. CGS were most often located in a cancer center (47%); no CGS were located in PC. Most referrals originated from oncology, surgery, or gastroenterology, with the lowest rate of referrals from community-based PC. Nearly half of CGS clinics (47%) reported capacity for at least a small increase in patient volume. Wait-time at the majority of CGS clinics was less than a month. GCs cited patient logistics (e.g. transportation, time off work), lack of referral information from providers, and systemic racism as significant barriers in patient access to CGS. Conclusions: After almost 20 years of evidence-based guidelines, use of HCRA is still very limited in the community-based PC setting. Our findings point to a need to bridge the gap between hospital-based CGS and FQHCs to ensure patients in vulnerable communities have access to guideline-concordant cancer prevention and screening strategies. Based on these findings, CCSTAC is designing strategies to integrate HCRA in primary care at FQHCs focused on provider education, well-designed clinic workflows, connections with existing CGS, and advocacy to align UDS and HEDIS measures with USPSTF guidelines.

Development and implementation of an equitable and efficient navigation program to address supportive care needs in patients with cancer.

58 Background: Despite evidence backing the use of navigation along the cancer care trajectory, existing programs struggle to deliver services efficiently and equitably. To bridge this gap, we developed and implemented a patient-centric, data-driven navigation program that leverages a risk-stratification approach to prioritize and address unmet needs. Methods: Our program was developed with key principles to address inefficiencies in existing navigation systems. First, we embedded the program within our institution’s Epic environment, using data-driven risk calculators, dashboards, flowsheets, and templates to support the navigation curriculum. Second, the program structure aligned with the patient’s journey from initial consult through treatment, focusing on early identification of unmet needs, centralized resourcing, and remote symptom monitoring for high-risk patients. Third, we unified the workflows of navigators, intake personnel, triage nurses, and providers, fostering system-wide collaboration. Results: The program has been successfully implemented in patients with new consults in gastrointestinal, breast, and hematologic oncology. To date, 2,080 patients have had an initial assessment leading to a Navigation Assessment Score (NAS) that predicts longitudinal burden of unmet needs and directs subsequent resourcing. 226 referrals have been generated to: cancer rehabilitation (76), nutrition (60), psychosocial oncology (48), tobacco cessation (39), and palliative care (3). Remote symptom monitoring was piloted in 34 gastrointestinal oncology patients meeting the calculated highest decile risk for unplanned acute care event use. Proportions of patients with a NAS score (N=2,080): 69.3% White, 17.7% Black, 3% Latinx, 1.8% Asian, 0.9% American Indian; referrals (N=226): 61.2% White, 23.0% Black, 4.9% Latinx, 1.1% Asian, 0.5% American Indian; remote symptom monitoring (N=34): 79.4% White, 11.8% Black, 5.9% American Indian. Except for Latinx patients, these distributions align with the patient population in gastrointestinal, breast, and hematologic oncology (N=4,267; 68.0% White, 22.5% Black, 6.4% Latinx, 1.9% Asian, 0.9% American Indian). Conclusions: Development and implementation of our program is feasible, and the approach has potential to mitigate disparities in cancer service delivery and outcomes. Ongoing efforts include exploring accessibility among Latinx patients and developing the business case for sustainability and scaling.

Research Priorities in Pediatric Asthma Morbidity: Addressing the Impacts of Systemic Racism on Children with Asthma in the United States. An Official American Thoracic Society Workshop Report.

Background: In the United States, Black and Latino children with asthma are more likely than White children with asthma to require emergency department visits or hospitalizations because of an asthma exacerbation. Although many cite patient-level socioeconomic status and access to health care as primary drivers of disparities, there is an emerging focus on a major root cause of disparities-systemic racism. Current conceptual models of asthma disparities depict the historical and current effects of systemic racism as the foundation for unequal exposures to social determinants of health, environmental exposures, epigenetic factors, and differential healthcare access and quality. These ultimately lead to biologic changes over the life course resulting in asthma morbidity and mortality. Methods: At the 2022 American Thoracic Society International Conference, a diverse panel of experts was assembled to identify gaps and opportunities to address systemic racism in childhood asthma research. Panelists found that to examine and address the impacts of systemic racism on children with asthma, researchers and medical systems that support biomedical research will need to 1) address the current gaps in our understanding of how to conceptualize and characterize the impacts of systemic racism on child health, 2) design research studies that leverage diverse disciplines and engage the communities affected by systemic racism in identifying and designing studies to evaluate interventions that address the racialized system that contributes to disparities in asthma health outcomes, and 3) address funding mechanisms and institutional research practices that will be needed to promote antiracism practices in research and its dissemination. Results: A thorough literature review and expert opinion discussion demonstrated that there are few studies in childhood asthma that identify systemic racism as a root cause of many of the disparities seen in children with asthma. Community engagement and participation in research studies is essential to design interventions to address the racialized system in which patients and families live. Dissemination and implementation studies with an equity lens will provide the multilevel evaluations required to understand the impacts of interventions to address systemic racism and the downstream impacts. To address the impacts of systemic racism and childhood asthma, there needs to be increased training for research teams, funding for studies addressing research that evaluates the impacts of racism, funding for diverse and multidisciplinary research teams including community members, and institutional and financial support of advocating for policy changes based on study findings. Conclusions: Innovative study design, new tools to identify the impacts of systemic racism, community engagement, and improved infrastructure and funding are all needed to support research that will address impacts of systemic racism on childhood asthma outcomes.

Rates of Reporting and Analyzing Race and Ethnicity in Athlete-Specific Sports Medicine Research: A Systematic Review.

Race- and ethnicity-based differences in treatment access and outcomes have been reported in the orthopaedic sports medicine literature. However, the rate at which race and ethnicity are reported and incorporated into the statistical analysis of sports medicine studies remains unclear. To determine the rate at which race and ethnicity are reported and analyzed in athlete-specific sports medicine literature. Systematic review; Level of evidence, 4. Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, articles published by the 3 journals of the American Orthopaedic Society for Sports Medicine between 2017 and 2021 were considered for inclusion. Original sports medicine research studies that focused on athletes were included. Outcome measures included reporting and analysis of patient demographics (age, sex, race, ethnicity). Studies that included demographic variables in a multivariate analysis or that performed a race-/ethnicity-based stratified analyses were considered to have analyzed that variable. Studies that reported and/or analyzed patient demographics were examined. Chi-square tests were performed to determine statistical significance. A total of 5140 publications were screened, and 842 met the inclusion criteria. Age and sex were well reported (84.1% and 87.0%, respectively), while race (3.8%) and ethnicity (2.0%) were poorly reported. There was no difference in rates of reporting age, sex, race, or ethnicity between the American Journal of Sports Medicine (AJSM), the Orthopaedic Journal of Sports Medicine (OJSM), or Sports Health: A Multidisciplinary Approach (Sports Health). The rate of analysis was also calculated as a percentage of the studies that reported that variable. Of the studies that reported age, 38.5% analyzed age. Using this method, 26.2% of studies analyzed sex, 40.6% analyzed race, and 17.6% analyzed ethnicity. Although there was no difference in the overall rate at which studies from the 3 journals analyzed ethnicity, Sports Health studies analyzed age (P = .044), sex (P = .001), and race (P = .027) more frequently than studies published in AJSM and OJSM. Of the studies that analyzed race, most of those studies (8/13, 61.5%) found significant race-based differences in reported outcomes. This systematic review demonstrated that race and ethnicity are poorly reported and analyzed in athlete-specific sports medicine literature, despite the fact that a majority of studies analyzing race found significant differences between racial groups. Improved reporting of race and ethnicity can determine whether race- and ethnicity-based differences exist in patient interventions to ameliorate disparities in patient outcomes.

Impact of delays in neoadjuvant chemotherapy initiation on pathologic complete response among patients with HER2-positive or triple negative breast cancer.

102 Background: Pathologic complete response (pCR) is used as a surrogate endpoint for overall survival (OS) in high-risk early-stage breast cancer (BC). pCR rates vary according to BC molecular subtype and have the highest association with OS in triple negative BC (TNBC) and HER2-positive (HER2+) BC. In these subgroups, neoadjuvant chemotherapy (NACT) is often the standard of care. We evaluated the association of delays in NACT initiation (NACTI) with pCR. Methods: We conducted a retrospective cohort study using the National Cancer Database. Eligibility included age ≥18 years, diagnosis cT2+ or lymph node positive HER2+ or TNBC between 1/1/2010 – 12/31/2020, who were treated with NACT within 180 days of BC diagnosis. Time to chemotherapy (TTC) was recorded in days. Patients were categorized by receptor status. We used AJCC 7 th and 8 th edition T and N staging to define pCR (pT0 or pTis and pN0 or pN0I-). Delay was defined as TTC > 60 days. Multivariable logistic regression, adjusted for demographic, socioeconomic and tumor characteristics, was used to calculate odds of pCR associated with delays. A sensitivity analysis defining delay >30 and >90 days was also conducted. Results: We identified 105,352 eligible patients, 73% were White, 19% were Black, 3% were Asian, and 4% were Other/Unknown. Median age at diagnosis was 52 years (range 18-90), median TTC was 32 days (range 0-180). There were 56,868 patients with HER2+ BC and 48,484 with TNBC; 9% of patients were delayed > 60 days in each group. Among all HER2+ patients, 39.1% achieved a pCR: 35.0% with delay compared to 39.5% without delay. Among TNBC patients, 30% achieved a pCR: 25% with delay compared to 31% without delay (p < 0.0001 for all). In multivariable analysis, patients with HER2+ disease (OR 0.85, 95%CI 0.79-0.92) and TNBC (OR 0.80, 95%CI 0.73-0.87) were less likely to achieve pCR if delayed > 60 days. In a sensitivity analysis, delay > 30 days was associated with lower likelihood of achieving pCR for all and delay > 90 days was associated with lower likelihood for TNBC (Table). Conclusions: Delays in NACTI >60 days among patients with HER2+ and TNBC BC was an independent predictor of not achieving pCR. Given the known association between socioeconomic factors and delays to initiation of treatment, interventions aimed at reducing delays may reduce disparities in BC outcomes. Future studies to identify causes of delays and the downstream impact are needed to ultimately develop interventions that mitigate these effects among patients with HER2+ or TNBC, where pCR rates are associated with OS. Association of pCR in patients who experience NACTI delay using multivariable logistic regression* n(complete case) = 77,690.

Exploring Rural-Urban Differences in the Receipt of Nonelective Cancer-specific Gastrointestinal Surgery Using a Multilevel Mixed-Effects Approach

BackgroundRural communities constitute a populace marked by various social challenges influencing health outcomes. As such, nonelective surgeries for cancer may have a disproportionate impact on rural populations. We explored patient and county-level factors contributing to differences in the receipt of nonelective cancer-specific surgery between rural and urban residents. MethodsThis retrospective study included adult patients captured in the SEER-Medicare data between January 2008 and December 2015 with an incident stage I-IV cancer of the stomach, liver/intrahepatic bile duct, pancreas, gallbladder/other biliary origin, or small intestine who underwent a cancer-specific surgery. The primary outcome was nonelective cancer-directed surgery among rural versus urban residents. We conducted a multivariable mixed-effects logistic regression model to adjust for confounders while accounting for county-level clustering. ResultsThe sample included 10,136 patients who underwent a surgical intervention; 2,941 (29%) were nonelective. The incidence of nonelective surgery was lower among rural compared tourban patients [351 (27%) and 2590(29%); p= 0.05]. There was no statistically significant difference in the unadjusted and adjusted odds of nonelective surgery between rural and urban residents [OR 0.88, 95% CI (0.76-1.03); p= 0.11] and [aOR 0.86, 95% CI (0.72-1.02); p= 0.080]. Additionally, high social vulnerability index counties or Black race was significantly associated with increase odds of nonelective surgery [aOR 1.33, 95% CI (1.07-1.65); p=0.009] and [aOR 1.49, 95% CI (1.26-1.77); p<0.0001], respectively. ConclusionThis study found no difference in the odds of receiving nonelective surgery for GI foregut cancers between rural and urban populations. However, Black race and high SVI were associated with higher odds of the receipt of nonelective surgery. Further research is warranted to explore if disparities in clinical outcomes exist despite the comparable likelihood of receiving nonelective surgery between rural and urban communities.

Racial Disparities and Strategies for Improving Equity in Diagnostic Follow-Up for Abnormal Screening Mammograms.

Black and White women undergo screening mammography at similar rates, but racial disparities in breast cancer outcomes persist. To assess potential contributors, we investigated delays in follow-up after abnormal imaging by race/ethnicity. Women who underwent screening mammography at our urban academic center from January 2015 to February 2018 and received a Breast Imaging Reporting and Data System 0 assessment were included. Kaplan-Meier estimates described distributions of time between diagnostic events from (1) screening to diagnostic imaging and (2) diagnostic imaging to biopsy. Multivariable logistic regression models estimated the associations between race/ethnicity and receipt of follow-up within 15 and 30 days. Two thousand five hundred and fifty-four women were included (48.6% non-Hispanic [NH] Black, 38.2% NH White, 13.1% other/unknown). Median time between screening and diagnostic imaging varied by race/ethnicity (White: 7 days [IQR, 2-14]; Black: 12 days [IQR, 7-23]; other/unknown: 9 days [IQR, 5-21]). There were similar disparities in days between diagnostic imaging and biopsy (White: 12 [IQR, 7-24]; Black: 21 [IQR, 13-37]; other/unknown: 16 [IQR, 9-30]) and between screening and biopsy (White: 20 [IQR, 11-41]; Black: 35 [IQR, 22-63]; other/unknown: 27.5 [IQR, 17-42]). After adjustment, odds of diagnostic imaging follow-up within 15 days of screening were lower for Black versus White women (odds ratio, 0.59 [95% CI, 0.44 to 0.80]; P < .001). In this diverse cohort, disparities in timely diagnostic follow-up after abnormal breast screening were observed, with Black women waiting 1.75 times as long as White women to obtain a tissue diagnosis. National guidelines for time to diagnostic follow-up may facilitate more timely breast cancer care and potentially affect outcomes.

Racial Differences in Adoption and Outcomes of Transcarotid Artery Revascularization among High-Risk Adults with Carotid Artery Stenosis

Differential access to new technologies may contribute to racial disparities in surgical outcomes but has not been well-studied in the treatment of carotid artery stenosis. We examined race-based differences in adoption and outcomes of transcarotid artery revascularization (TCAR) among high-risk non-Hispanic (NH) NH Black and NH white adults undergoing carotid revascularization. We conducted a retrospective analysis of TCAR, transfemoral carotid artery stenting (TF-CAS), and carotid endarterectomy (CEA) procedures performed for carotid artery stenosis from 1/2015 to 7/2023 in the Vascular Quality Initiative. NH Black and NH white adults were included if they met Centers for Medicare & Medicaid Services high-risk criteria. Hospitals and physicians were categorized as TCAR-capable if they had previously performed at least one TCAR prior to the time of a given procedure. We fit logistic and linear regressions, adjusted a priori for common demographic, clinical, and disease characteristics, to estimate associations of race with receipt of TCAR (versus CEA or TF-CAS), and to explore associations between race, hospital and physician characteristics, and perioperative composite stroke/death/myocardial infarction. Of 159,471 high-risk patients undergoing revascularization for carotid artery stenosis (mean age 72 years, 38.5% female, 5.3% NH Black), 28,722 (18.0%) received TCAR, including 16.9% of NH Black adults and 18.1% of NH white adults (P<0.001). After controlling for patient and disease characteristics, NH Black patients were less likely than NH white patients to receive TCAR (aOR 0.92, 95% CI 0.87 to 0.99). The use of TCAR did not vary by race among patients treated at TCAR-capable hospitals (aOR 0.98, 95% CI 0.91 to 1.05) or by TCAR-capable physicians (aOR 1.01, 95% CI 0.93 to 1.10); however, NH Black race was associated with lower odds of receiving treatment in these settings (TCAR-capable hospital: aOR 0.93 [0.88 to 0.98]; TCAR-capable physician: aOR 0.92 [0.87 to 0.98]). NH Black race was associated with higher odds of stroke/death/MI in the full cohort (aOR 1.18, 95% CI 1.03 to 1.36), but not in the subgroup of patients who received TCAR (aOR 0.87, 95% CI 0.56 to 1.34). TCAR attenuated racial disparities in perioperative morbidity and mortality associated with carotid revascularization, but NH Black adults were less likely than NH white adults to receive TCAR. Relatively worse access for NH Black adults to technologically-advanced treatment settings may partially explain the broader persistence of race-based differences in carotid revascularization treatment patterns and outcomes.

Disparities in cancer mortality outcomes among adult immigrants in the United States.

134 Background: The “immigrant health paradox” posits that immigrants are generally healthier than US natives of similar demographic and socioeconomic background. However, immigrant noncitizens with cancer face unique barriers to care, including limited access to routine screening and continuous healthcare coverage, which may portend worse outcomes. Methods: The 2011-2018 National Health Interview Survey Linked Mortality Files were used to identify all adult (age ≥18 years) US natives, foreign-born citizens, and noncitizens with a cancer history. Differences by group were assessed using the chi-squared test with Rao &amp; Scott’s second-order correction. Cox-proportional hazards models tested associations between nativity/citizenship status and cancer-specific (CSM) and all-cause mortality (ACM), adjusted by age, gender, and survey year. Sequential models separately tested the added effects of individual patient-level covariates selected a priori —including race/ethnicity, smoking status, region, educational attainment, employment, insurance status, and having a usual source of care. Results: A total of 23,603,743 US natives, 1,647,188 foreign-born citizens and 477,861 noncitizens met criteria for inclusion. Compared to US natives, immigrants had significantly greater distribution of gastroesophageal (2.3%, noncitizens vs 2.3%, foreign-born citizens vs 1.0%, US natives, p &lt;0.001), head &amp; neck (8.4% vs 6.2% vs 4.4%, p =0.003), and lung cancers (3.1% vs 4.2% vs 2.8%, p =0.03). Of the1,302,0771 US natives, 105,258 foreign-born citizens, and 21,937 noncitizens who died during the study period, cancer was the primary cause of death for 52% of noncitizens and 62% of foreign-born citizens (vs 44%, p &lt;0.001). Lung cancer was the most common diagnosis in this group, accounting for 40% of cancer deaths among non-citizens (vs 19% vs 13%; p =0.03). Relative to US natives, foreign-born citizens had a significantly lower risk of all-cause (adjusted HR [95%CI], 0.67 [0.54-0.83]) but not cancer-specific mortality (0.94 [0.71-1.23]); no differences in mortality risk among noncitizens were observed. On subset analysis limited to adults with lung cancer, noncitizens had over twice the hazard of cancer death (2.72 [1.22-6.09]) as well as death from any cause (2.14 [1.01-4.55]). While the association with ACM was no longer significant in sequential models, the association remained significant for CSM. Importantly, insurance status attenuated but did not eliminate the risk of lung cancer death for noncitizens (2.63 [1.16-5.96]). Conclusions: Although immigrant noncitizens did not have a significantly greater risk of cancer death overall, those with lung cancer were more than twice as likely to die from their disease, even after adjustment for patient-level variables, including insurance status and having a usual source of care. Future research is warranted to identify root causes and potential points for intervention.

The Maternal and Infant Health Consequences of Restricted Access to Abortion in the United States

Since the recent US Supreme Court decision in Dobbs v. Jackson Women's Health Organization, people across the country have experienced large sudden changes in their access to abortion care. In this paper, I look to the history of abortion access in the United States to inform predictions for this new future. I study the effects of targeted regulations on abortion providers (TRAP laws) on a variety of maternal and infant health outcomes, using variation in the timing of policy adoption across states and a direct measure of the distance to an abortion provider. I implement difference-in-differences techniques across outcomes from restricted-use microdata on the universe of US births. I find that TRAP laws lead to 11-16% increased rates of hypertensive disorders of pregnancy. Additionally, I find evidence that TRAP laws widen existing disparities in adverse infant health outcomes across parental race. These results demonstrate the potentially wide-ranging health effects of restricting access to abortion.
