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., (© 2022.

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., (© 2023 The Authors.

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., (© 2022.

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., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

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.

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/m 2 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/m 2 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/m 2 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/m 2 were at elevated risk of a preterm or early term birth. Women with BMI ≥25.0 kg/m 2 were at elevated risk of a birth <28 weeks. Propensity score-matched women with BMI ≥30.0 kg/m 2 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/m 2 were at decreased risk of a late spontaneous preterm birth., (© 2022 John Wiley & Sons Ltd.)

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., Competing Interests: No competing financial interests exist., (© Brittany D.

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., (© 2021.

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., (© 2021.

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., (© The Author(s) 2020.

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., (© 2020. W.

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., (Copyright © 2021 Elsevier Inc.

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., (© 2021 John Wiley & Sons Ltd.)

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.

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.

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.

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.

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.

Brown marmorated stink bug (Halyomorpha halys) (Stål) is a household nuisance pest that seeks shelter in buildings during the winter months. It has been found in a variety of cavities and spaces between building elements, as well as in the objects stored within buildings. This experiment examined the cavity tightness preferences for these insects as they settled in winter refugia. Adult overwintering H. halys were placed in two types of simulated refugia made from rigid material. Each type had a cavity of constant width, while one had a flat lid and constant tightness, and the other had a sloped lid that became tighter as insects moved inside. Adults were allowed to enter and settle, then their locations were recorded. In sloped lid cavities, H. halys tended to settle where the cavity tightness was between 4.5 and 5.5 mm. In the flat lid cavity boxes, H. halys tended to move all the way back. In both configurations, H. halys had a significant tendency to orient their heads towards the cavity entrance. A field comparison of cavity tightness in refugia with less rigid cardboard substrates was also performed, with spacers consisting of one or two layers of 3-mm cardboard. This comparison found differences in cavity selection by sex, with males more likely to pick single-spaced layers, and females more likely to select double-spaced layers. Understanding these preferences could be useful for collection, pest management, trap design, and study of impacts on structures., (© The Author(s) 2020.

Research supports that exposure to stressors (e.g., perceived stress and racism) during pregnancy can negatively impact the immune system, which may lead to infection and ultimately increases the risk for having a preterm or low-birthweight infant. It is well known that Black women report higher levels of stressors at multiple timepoints across pregnancy compared with women of all other racial and ethnic groups. This study addresses gaps in the literature by describing pregnant and early post-partum Black women's exposures to structural racism and self-reported experiences of racial discrimination, and the extent to which these factors are related. We used a cross-sectional study design to collect data related to exposures to racism from pregnant and early post-partum Black women residing in Oakland, California, from January 2016 to December 2017. Comparative analysis revealed that living in highly deprived race + income neighborhoods was associated with experiencing racial discrimination in three or more situational domains (p = .01). Findings show that Black women are exposed to high levels of racism that may have negative impacts on maternal health outcomes., (© 2020 John Wiley & Sons, Ltd.)

Background: Higher socioeconomic status (SES) has less impact on cardio-metabolic disease and preterm birth risk among Black women compared to White women, an effect called "diminishing returns." No studies have tested whether this also occurs for pregnancy cardio-metabolic disease, specifically preeclampsia, or whether preeclampsia risk could account for race-by-SES disparities in birth timing., Methods: A sample of 718,604 Black and White women was drawn from a population-based California cohort of singleton births. Education, public health insurance status, gestational length, and preeclampsia diagnosis were extracted from a State-maintained birth cohort database. Age, prenatal care, diabetes diagnosis, smoking during pregnancy, and pre-pregnancy body mass index were covariates., Results: In logistic regression models predicting preeclampsia risk, the race-by-SES interaction (for both education and insurance status) was significant. White women were at lower risk for preeclampsia, and higher SES further reduced risk. Black women were at higher risk for preeclampsia, and SES did not attenuate risk. In pathway analyses predicting gestational length, an indirect effect of the race-by-SES interaction was observed. Among White women, higher SES predicted lower preeclampsia risk, which in turn predicted longer gestation. The same was not observed for Black women., Conclusions: Compared to White women, Black women had increased preeclampsia risk. Higher SES attenuated risk for preeclampsia among White women, but not for Black women. Similarly, higher SES indirectly predicted longer gestational length via reduced preeclampsia risk among White women, but not for Black women. These findings are consistent with diminishing returns of higher SES for Black women with respect to preeclampsia.

Background: While there is a growing interest in addressing social determinants of health in clinical settings, there are limited data on the relationship between unstable housing and both obstetric outcomes and health care utilization., Objective: The objective of the study was to investigate the relationship between unstable housing, obstetric outcomes, and health care utilization after birth., Study Design: This was a retrospective cohort study. Data were drawn from a database of liveborn neonates linked to their mothers' hospital discharge records (2007-2012) maintained by the California Office of Statewide Health Planning and Development. The analytic sample included singleton pregnancies with both maternal and infant data available, restricted to births between the gestational age of 20 and 44 weeks, who presented at a hospital that documented at least 1 woman as having unstable housing using the International Classification of Diseases, ninth edition, codes (n = 2,898,035). Infants with chromosomal abnormalities and major birth defects were excluded. Women with unstable housing (lack of housing or inadequate housing) were identified using International Classification of Diseases, ninth edition, codes from clinical records. Outcomes of interest included preterm birth (<37 weeks' gestational age), early term birth (37-38 weeks gestational age), preterm labor, preeclampsia, chorioamnionitis, small for gestational age, long birth hospitalization length of stay after delivery (vaginal birth, >2 days; cesarean delivery, >4 days), emergency department visit within 3 months and 1 year after delivery, and readmission within 3 months and 1 year after delivery. We used exact propensity score matching without replacement to select a reference population to compare with the sample of women with unstable housing using a one-to-one ratio, matching for maternal age, race/ethnicity, parity, prior preterm birth, body mass index, tobacco use during pregnancy, drug/alcohol abuse during pregnancy, hypertension, diabetes, mental health condition during pregnancy, adequacy of prenatal care, education, and type of hospital. Odds of an adverse obstetric outcome were estimated using logistic regression., Results: Of 2794 women with unstable housing identified, 83.0% (n = 2318) had an exact propensity score-matched control. Women with an unstable housing code had higher odds of preterm birth (odds ratio, 1.2, 95% confidence interval, 1.0-1.4, P < .05), preterm labor (odds ratio, 1.4, 95% confidence interval, 1.2-1.6, P < .001), long length of stay (odds ratio, 1.6, 95% confidence interval, 1.4-1.8, P < .001), emergency department visits within 3 months (odds ratio, 2.4, 95% confidence interval, 2.1-2.8, P < .001) and 1 year after birth (odds ratio, 2.7, 95% confidence interval, 2.4-3.0, P < .001), and readmission within 3 months (odds ratio, 2.7, 95% confidence interval, 2.2-3.4, P < .0014) and 1 year after birth (odds ratio, 2.6, 95% confidence interval, 2.2-3.0, P < .001)., Conclusion: Unstable housing documentation is associated with adverse obstetric outcomes and high health care utilization. Housing and supplemental income for pregnant women should be explored as a potential intervention to prevent preterm birth and prevent increased health care utilization., (Copyright © 2019 Elsevier Inc.

Background: Blended learning is a combination of online learning and face-to-face instruction, and is increasingly being used in K-12 settings. A meta-analysis conducted for the Department of Education suggests blended learning is more effective than either group-based or online learning alone, particularly in K-12 settings., Methods: This paper provides a narrative review of the literature from 2000 to 2017 on blended learning as it applies to sexual health education programs, and discusses outcomes, best practices and potential challenges of blended learning that may be important for practitioners and researchers considering this approach., Results: Blended learning approaches are being used successfully in sexual health education programs, including school-based programs, and have yielded positive behavioral and psychosocial changes. Similar to traditional group-based programs, not all outcomes tested in these programs showed positive impact. Designing blended learning programs can be challenging, but there is a large best-practice literature that can inform practitioners interested in using it., Conclusions: Blended learning approaches are viable for sexual health education and offer numerous advantages to group-based only programs, such as confidential personalization and an instructional approach that is familiar and engaging for participants., (© 2019, American School Health Association.)

Intentional and unintentional openings in a building's envelope provide opportunities for unwanted pests to enter buildings. The brown marmorated stink bug, Halyomorpha halys (Stål), is one such pest, causing a significant domestic winter nuisance in many locations. One important means of pest control is exclusion, or blocking openings through which they can enter, although some openings are intentional and cannot be completely blocked without putting a building at risk. To help understand what size openings are relevant to entry, adult H. halys ready for overwintering were driven out of heated boxes through openings designed to limit passage by their lateral pronotal and dorsoventral dimensions. Pronotally limited holes of 8 mm wide were passed by only one female (3.3% of those tested), and no females and only one male (3.3%) passed through 7-mm-wide holes. For dorsoventrally limited slits, few (13%) of females passed through 4-mm-high slits, and no individuals passed through 3-mm-high slits. Dorsoventral heights and pronotal widths of 930 individuals collected in Virginia were measured. Females were consistently larger, with pronota averaging 8.33 mm wide to the males' 7.47 mm and heights at the point of leg movement restriction averaging 4.03 mm to the males' 3.50 mm. Based on experimental data and size data, we conclude that most H. halys individuals will be excluded by slits smaller than 3 mm and holes smaller than 7 mm., (© The Author(s) 2019.

Overwintering brown marmorated stink bugs (Halyomorpha halys) (Stål) are a notable domestic nuisance. In addition to disruptive activity, dead individuals remain in homes, sometimes in large numbers. To better understand the effects of these remains on overwintering behavior, adult H. halys were subjected to several experiments to test their responses to dead conspecifics. In non-tactile tests of individuals exposed to groups of dead conspecifics, H. halys did not respond to 1-yr-old desiccated dead conspecifics, but avoided corpses that were freshly killed. In tactile tests of individuals exposed to groups of dead conspecifics, H. halys joined those corpse aggregations significantly more often than not, and preferred corpses to cotton when given a choice. In tests of exposure of overwintering individuals to fresh dead conspecifics over the course of a winter, no necrophagy or evidence of survival advantage was observed, but overall females had higher survival rates than males., (© The Author(s) 2019.

Disparities in adverse birth outcomes for Black women continue. Research suggests that societal factors such as structural racism explain more variation in adverse birth outcomes than individual-level factors and societal poverty alone. The Index of Concentration at the Extremes (ICE) measures spatial social polarization by quantifying extremes of deprived and privileged social groups using a single metric and has been shown to partially explain racial disparities in black carbon exposures, mortality, fatal and non-fatal assaults, and adverse birth outcomes such as preterm birth and infant mortality. The objective of this analysis was to assess if local measures of racial and economic segregation as proxies for structural racism are associated and preterm birth and infant mortality experienced by Black women residing in California. California birth cohort files were merged with the American Community Survey by zip code (2011-2012). The ICE was used to quantify privileged and deprived groups (i.e., Black vs. White; high income vs. low income; Black low income vs. White high income) by zip code. ICE scores range from - 1 (deprived) to 1 (privileged). ICE scores were categorized into five quintiles based on sample distributions of these measures: quintile 1 (least privileged)-quintile 5 (most privileged). Generalized linear mixed models were used to test the likelihood that ICE measures were associated with preterm birth or with infant mortality experienced by Black women residing in California. Black women were most likely to reside in zip codes with greater extreme income concentrations, and moderate extreme race and race + income concentrations. Bivariate analysis revealed that greater extreme income, race, and race + income concentrations increased the odds of preterm birth and infant mortality. For example, women residing in least privileged zip codes (quintile 1) were significantly more likely to experience preterm birth (race + income ICE OR = 1.31, 95% CI = 1.72-1.46) and infant mortality (race + income ICE OR = 1.70, 95% CI = 1.17-2.47) compared to women living in the most privileged zip codes (quintile 5). Adjusting for maternal characteristics, income, race, and race + income concentrations remained negatively associated with preterm birth. However, only race and race + income concentrations remained associated with infant mortality. Findings support that ICE is a promising measure of structural racism that can be used to address racial disparities in preterm birth and infant mortality experienced by Black women in California.

Objective To develop a pre-pregnancy or first-trimester risk score to identify women at high risk of preterm birth. Study design In this retrospective cohort analysis, the sample was drawn from California singleton livebirths from 2007 to 2012 with linked birth certificate and hospital discharge records. The dataset was divided into a training (2/3 of sample) and a testing (1/3 of sample) set for discovery and validation. Predictive models for preterm birth using pre-pregnancy or first-trimester maternal factors were developed using backward stepwise logistic regression on a training dataset. A risk score for preterm birth was created for each pregnancy using beta-coefficients for each maternal factor remaining in the final multivariable model. Risk score utility was replicated in a testing dataset and by race/ethnicity and payer for prenatal care. Results The sample included 2,339,696 pregnancies divided into training and testing datasets. Twenty-three maternal risk factors were identified including several that were associated with a two or more increased odds of preterm birth (preexisting diabetes, preexisting hypertension, sickle cell anemia, and previous preterm birth). Approximately 40% of women with a risk score ≥ 3.0 in the training and testing samples delivered preterm (40.6% and 40.8%, respectively) compared to 3.1-3.3% of women with a risk score of 0.0 [odds ratio (OR) 13.0, 95% confidence interval (CI) 10.7-15.8, training; OR 12.2, 95% CI 9.4-15.9, testing). Additionally, over 18% of women with a risk score ≥ 3.0 had an adverse outcome other than preterm birth. Conclusion Maternal factors that are identifiable prior to pregnancy or during the first-trimester can be used create a cumulative risk score to identify women at the lowest and highest risk for preterm birth regardless of race/ethnicity or socioeconomic status. Further, we found that this cumulative risk score could also identify women at risk for other adverse outcomes who did not have a preterm birth. The risk score is not an effective screening test, but does identify women at very high risk of a preterm birth., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Latinos are the largest growing population and have the highest fertility rates in the US. In response, this study assessed if late initiation of or no prenatal care (PNC) mediated the relationship among adverse birth outcomes and interactions between immigrant and insurance status. This study used cross-sectional data (2002-2004) limited to 109,399 women of Mexican ethnicity who had singleton births in the San Joaquin Valley, California. We conducted hierarchical mediation analyses. US-born Mexican women who used private or public insurance for PNC were more likely to have infants born at low-birth weight and premature compared to Mexican first generation immigrant women. Nonetheless, initiation of late or no PNC positively mediated the relationship between infants born premature to Mexican first generation immigrant women who used public insurance (ab/se(ab) = 2.123, p = .034). Findings from this study support acculturation theory and the need for multilevel approaches to address PNC among women of Mexican ethnicity.

Despite decreases in infants born premature and at low birth weight in the United States (U.S.), racial disparities between Black and White women continue. In response, the purpose of this analysis was to examine associations between both traditional and novel indicators of county-level structural racism and birth outcomes among Black and White women. We merged individual-level data from the California Birth Statistical Master Files 2009-2013 with county-level data from the United States (U.S.) Census American Community Survey. We used hierarchical linear modeling to examine Black-White differences among 531,170 primiparous women across 33 California counties. Traditional (e.g., dissimilarity index) and novel indicators (e.g., Black to White ratio in elected office) were associated with earlier gestational age and lower birth weight among Black and White women. A traditional indicator was more strongly associated with earlier gestational age for Black women than for White women. This was the first study to empirically demonstrate that structural racism, measured by both traditional and novel indicators, is associated with poor health and wellbeing of infants born to Black and White women. However, findings indicate traditional indicators of structural racism, rather than novel indicators, better explain racial disparities in birth outcomes. Results also suggest the need to develop more innovative approaches to: (1) measure structural racism at the county-level and (2) reform public policies to increase integration and access to resources.

Background HIV-positive women in the United States can have healthy pregnancies and avoid transmitting HIV to their children. Yet, little is known about the extent to which HIV care providers' reproductive health practices match women's pregnancy desires. Accordingly, we explored young HIV-positive women's pregnancy desires and reproductive health behaviors and examined reproductive health information offered by HIV care clinics. Methods A mixed-method analysis was conducted using data from a 14-site Adolescent Medicine Trials Network (ATN) study. We conducted descriptive statistics on data from 25 HIV-positive women (e.g., demographics, pregnancy desires, and sexual- and health-related behaviors). Qualitative interviews with 58 adolescent and adult clinic providers were analyzed using the constant comparative method. Results About half of the women reported using reproductive health care services (i.e., contraception and pregnancy tests) (n = 12) and wanted a future pregnancy (n = 13). Among women who did not desire a future pregnancy (n = 5), three used dual methods and two used condoms at last sexual encounter. Qualitative themes related to clinics' approaches to reproductive health (e.g., "the emphasis…is to encourage use of contraceptives") and the complexity of merging HIV and reproductive care (e.g., "We [adolescent clinic] transition pregnant moms from our care back and forth to adult care"). Discussion Despite regular HIV-related medical appointments, HIV-positive women may have unaddressed reproductive health needs (e.g., pregnancy desire with providers focused on contraceptive use). Findings from this study suggest that increased support for young HIV-positive women's reproductive health is needed, including supporting pregnancy desires (to choose when, how, and if, to have children).

Purpose: Youth living with HIV (YLHIV) in the United States (U.S.) account for nearly one-third of new HIV infections and face significant barriers to care engagement; only 25% are virally suppressed. Healthcare transition (HCT) from pediatric/adolescent to adult-oriented care can be particularly disruptive. Accordingly, we prospectively examined HCT processes at 14 distinct geographical sites across the U.S., Methods: We collected Audio Computer-Assisted Self-Interviews data and abstracted electronic medical records from 135 HCT-eligible YLHIV at baseline and 9-month follow-up. Descriptive analyses and multilevel modeling were conducted. Data also included qualitative interviews with 28 adolescent and 30 adult providers across 14 adolescent and 20 adult clinics, respectively. Interviews were analyzed using the constant comparative method; this analysis focused on specific HCT recommendations., Results: At baseline, youth were primarily age 24 (78.8%), male (76.8%), black (78.0%), identified as a sexual minority (62.9%), had attended an HIV appointment in the past 3 months (90.2%), had Medicaid for insurance (65.2%), and were always or mostly always adherent to their antiretroviral therapy (65.9%). At the 9-month follow-up only 37% of YLHIV successfully transitioned to adult care. Both individual-level (insurance status and disclosure-related stigma) and clinic-level (adolescent clinic best practices) factors were significant. Adolescent and adult clinic staff offered recommendations to support HCT; these focused primarily on clinical changes., Conclusions: This study highlights the complex set of individual- and clinic-level factors associated with HCT. Addressing these key factors is essential for developing streamlined, comprehensive, and context-specific HCT protocols to support continuous care engagement for YLHIV., (Copyright © 2018 The Society for Adolescent Health and Medicine.

Criminal justice practices in the USA disproportionately affect sexual and racial/ethnic minority men, who are at higher risk of incarceration. Previous research demonstrates associations between incarceration and sexual risk behaviors for men who have sex with men (MSM). However, little of this work focuses on young MSM (YMSM), particularly HIV-infected YMSM, despite nearly one-third reporting engagement in sexual risk behaviors, such as transactional sex. We therefore explored the association between incarceration and transactional sex among HIV-infected YMSM. We recruited 97 HIV-infected YMSM across 14 clinical sites in urban centers from August 2015 to February 2016. We used multivariate logistic regression to examine the relationship between incarceration and transactional sex among YMSM. The majority was 24 years old (78%) and racial/ethnic minority (95%); over half were not in school and reported an annual income of < $12,000. In the multivariate model, having ever been incarcerated (aOR = 3.20; 95% CI 1.07-9.63) was independently associated with a history of transactional sex. Being 24 years vs. younger (aOR = 9.68; 95% CI 1.42-65.78) and having ever been homeless (aOR = 3.71, 95% CI 1.18-11.65) also remained independently associated with a history of transactional sex. This analysis fills a gap in the literature by examining the relationship between incarceration and transactional sex among HIV-infected YMSM. Facilitating youths' engagement with social services available in their HIV clinic may serve as a key strategy in promoting health. Public health efforts need to address social-structural factors driving disproportionate rates of arrest and incarceration and related harms among this population.

Background: Adolescence is a critical phase of development and experimentation with delinquent behaviors. There is a growing body of literature exploring individual and structural impacts of discrimination on health outcomes and delinquent behaviors. However, there is limited research assessing how school diversity and discrimination impact students' delinquent behaviors. In response, the purpose of this study was to assess if individual- and school-level indicators of discrimination and diversity were associated with student delinquent behaviors among African American and White students., Methods: We analyzed Wave I (1994-1995) data from the National Longitudinal Study of Adolescent Health. Our analysis was limited to 8947 African American and White students (73% White, 48% male, and 88% parent ≥ high school education). We used multilevel zero-inflated negative binomial regression to test the association of individual- and school characteristics and discrimination with the number of self-reported delinquent behaviors., Results: Race, sex, perceived peer inclusion, and teacher discrimination were predictors of students' delinquent behaviors. The average school perceived peer inclusion and percentage of African Americans in teaching roles were associated with delinquent behaviors., Conclusions: Findings from this study highlight the potential for intervention at the interpersonal and school levels to reduce delinquency among African American and White students., (© 2018, American School Health Association.)

Background: Emerging research has begun to examine the breastfeeding experiences among racial/ethnic minority women. However, limited research to date has explored the potential factors that impact Latina mothers' breastfeeding through a multi-level lens. We examined the context of breastfeeding among Latina mothers in an exploratory study., Methods: We conducted semi-structured interviews with a convenience sample of 9 Latina mothers. Guided by the social-ecological model, thematic content analysis was used., Results: Latina mothers described individual- (e.g., knowledge of breastfeeding), interpersonal- (e.g., social support and norms), institutional- (e.g., healthcare system), and community-level (e.g., cultural norms) influences on their breastfeeding. Mothers recommended provision of bilingual and bicultural health professionals, information on US breastfeeding norms, and Latino-friendly informational materials in other languages., Conclusions: Considering the multi-level factors that shape Latina mothers' breastfeeding is essential to develop and implement culturally tailored initiatives and facilitate access to breastfeeding support to improve maternal and infant health., Competing Interests: Conflict of Interest Statement: The authors report no potential conflict of interests.

It is important for both individual- and population-level health that HIV-infected individuals progress through the Care Continuum. However, HIV-infected youth frequently disengage from care during transition from pediatric/adolescent to adult care; only 50% remain in adult care after 1 year. Understanding how providers define and approach a successful healthcare transition can improve the delivery of HIV-related services during critical years of HIV treatment. We conducted 58 staff interviews across 14 Adolescent Trials Network clinics (n = 30) and 20 adult clinics (n = 28). We used the constant comparative method to examine how providers defined and approached youths' successful transition. Providers identified four components critical to successful transition: (1) clinical outcomes (e.g., medication adherence and viral suppression); (2) youth knowing how to complete treatment-related activities (e.g., refilling prescriptions and making appointments); (3) youth taking responsibility for treatment-related activities and their overall health (e.g., "when they stop reaching out to the adolescent [clinic] to solve all their problems."); and (4) youth feeling a connection and trust toward the adult clinic (e.g., "they feel safe here"), with some providers even prioritizing connectedness over clinical outcomes (e.g., "Even if they're not taking meds but are connected [to care], …that's a success."). The identification of key components of successful transition can guide focused interventions and resources to improve youth maintenance in the HIV Care Continuum as they transition to adult care. Identifying what facilitates successful transitions, and the gaps that interventions can target, will help to ensure HIV-infected youth remain healthy across their lifespan.

HIV-infected adolescents have disproportionately low rates of care retention and viral suppression. Approximately half disengage from care while transitioning to adult clinics, in part due to fragmented care systems and lack of streamlined protocols. We conducted 58 qualitative interviews with social service and health care providers across 14 Adolescent Trials Network clinics (n = 28) and 20 adult clinics that receive transitioning adolescents (n = 30) from August 2015-June 2016. We used the constant comparative approach to examine processes, barriers, and facilitators of adult care transition. Transition barriers coalesced around three levels. Structural: insurance eligibility, transportation, and HIV-related stigma; Clinical: inter-clinic communication, differences in care cultures, and resource/personnel limitations; and Individual: adolescents' transition readiness and developmental capacity. Staff-initiated solutions (e.g., grant-funded transportation) were often unsustainable and applied individual-level solutions to structural-level barriers. Comprehensive initiatives, which develop collaborative policies and protocols that support providers' ability to match the solution and barrier level (i.e., structural-to-structural), are sorely needed. These initiatives should also support local systematic planning to facilitate inter-clinic structures and communication. Such approaches will help HIV-infected adolescents transition to adult care and improve long-term health outcomes.

Purpose: The HIV Care Continuum highlights the need for HIV-infected youth to be tested, linked, and maintained in lifelong care. Care engagement is important for HIV-infected youth in order for them to stay healthy, maintain a low viral load, and reduce further transmission. One point of potential interruption in the care continuum is during health care transition from adolescent- to adult-centered HIV care. HIV-related health care transition research focuses mainly on youth and on adolescent clinic providers; missing is adult clinic providers' perspectives., Methods: We examined health care transition processes through semi-structured interviews with 28 adult clinic staff across Adolescent Trials Network sites. We also collected quantitative data related to clinical characteristics and transition-specific strategies., Results: Overall, participants described health care transition as a "warm handoff" and a collaborative effort across adolescent and adult clinics. Emergent transition themes included adult clinical care culture (e.g., patient responsibility), strategies for connecting youth to adult care (e.g., adolescent clinic staff attending youth's first appointment at adult clinic), and approaches to evaluating transition outcomes (e.g., data sharing). Participants provided transition improvement recommendations (e.g., formalized protocols)., Conclusions: Using evidence-based research and a quality improvement framework to inform comprehensive and streamlined transition protocols can help enhance the capacity of adult clinics to collaborate with adolescent clinics to provide coordinated and uninterrupted HIV-related care and to improve continuum of care outcomes., (Copyright © 2017 Society for Adolescent Health and Medicine.

Purpose: We assessed the extent to which implementing adolescent pregnancy prevention programs in conjunction with three level implementation strategies reduces adolescent pregnancy rates at the county-level in North Carolina (NC)., Methods: Fixsen and colleagues' (2005) three levels of implementation were used to organize the prevention strategies: core (e.g., training, fidelity monitoring), organizational (e.g., administrative support), and external (e.g., community resources)., Results: Counties that had adolescent friendly clinic/services (external) were more likely to report lower adolescent pregnancy rates in comparison to counties that did not have access to such services., Conclusions: Findings suggest external implementation strategies are key to reducing adolescent pregnancy rates., (Copyright © 2016 Elsevier B.V.
