RESUMO
OBJECTIVE: To use a novel measure of systemic racism to examine its relationship with Non-Hispanic Black (NHB) to Non-Hispanic White (NHW) racial disparities in infant mortality across U.S. counties. STUDY DESIGN: In this cross-sectional study, a composite, multi-dimensional measure of systemic racism at the county level was developed using confirmatory factor analysis based on indicators across five dimensions of systemic racism. Using linear regression analysis, we examined the relationship between the systemic racism factor scores and the NHB to NHW racial disparities in county-level infant mortality rates. Additionally, we performed a multi-level analysis of infant mortality, with births nested within counties by running a random intercept model that controlled for factors at both the individual and county levels to take into account the clustered nature of the data. RESULTS: There were 325 counties that met inclusion criteria for the county level analysis and 1181 counties for the individual level analysis. Each one standard deviation increase in the Systemic Racism Index was associated with an increase of 10.4% in the Non-Hispanic Black to Non-Hispanic White infant mortality rate ratio at the county level (aOR 1.104, 95% CI [1.061-1.148]). After controlling for individual level clinical factors and county level factors, each one standard deviation increase in the systemic racism index score was associated with a decrease of 3.5% in the NHW infant mortality rate (aOR 0.965, 95% CI [0.943-0.988]). CONCLUSION: Systemic racism is significantly associated with differences between counties in the magnitude of their Non-Hispanic Black to Non-Hispanic White racial disparities in infant mortality rates.
RESUMO
Objective: Outside of pregnancy, proactive coping has been associated with both mental and physical well-being and with improved quality of life in chronic disease, but its effects in pregnancy are understudied. Our objective was to evaluate whether early pregnancy proactive coping was associated with adverse perinatal outcomes. Study Design: This was a planned secondary analysis of nulliparous pregnant people recruited from a tertiary care center. Participants completed a validated assessment of proactive coping (Proactive Coping Scale) at 8-20 weeks and were followed longitudinally through delivery. Detailed pregnancy and delivery data were collected by trained research personnel. The primary outcome was a composite of adverse perinatal outcomes including unplanned cesarean delivery, gestational diabetes, and hypertensive disorders of pregnancy. Secondary analyses included individual perinatal composite components and a neonatal morbidity composite measure. Multivariate regression compared adverse perinatal outcomes by Proactive Coping Scale quartile, controlling for a priori confounders. Results: Of the 281 parturients, the median Proactive Coping Scale score was 45.0 (range 25-55), and 47% experienced an adverse perinatal outcome. After adjusting for confounders, those in the lowest Proactive Coping Scale quartile had 2.2 times higher odds of experiencing an adverse perinatal outcome compared to those in the highest Proactive Coping Scale quartile. There were no differences in odds of the individual composite components or the adverse neonatal outcome. Conclusion: Lower early pregnancy proactive coping scores are associated with significant increase in adverse perinatal outcomes. Interventions that target improving proactive coping may be a novel mechanism for reducing perinatal morbidity.
Proactive coping is the process of preparing for a stressor or goal, which has been studied in the context of chronic disease. We sought to understand how proactive coping relates to pregnancy outcomes. Our results indicated that higher proactive coping scores were associated with lower risk of adverse pregnancy outcomes. Therefore, interventions to increase proactive coping may have a role in reducing adverse pregnancy outcomes.
RESUMO
INTRODUCTION: Outside of pregnancy, evidence shows that persons with HIV initiating or switching to dolutegravir (DTG)-based antiretroviral therapy (ART) experience greater weight gain compared to those on other ART classes. However, there are few data on the impact of DTG-based ART on gestational weight gain (GWG) in sub-Saharan Africa where HIV is most common. According to the National Academy of Medicine (NAM), GWG below and above NAM guidelines is associated with adverse birth outcomes. Therefore, the objective of this study was to describe GWG by HIV status and ART regimen, and examine the associations with adverse birth outcomes. METHODS: We enrolled pregnant women with HIV (WHIV) and without HIV (≥18 years) in a peri-urban primary healthcare facility in Cape Town, South Africa between 2019 and 2022. GWG was study-measured at 24-28 (baseline) and 33-38 weeks gestation and converted to GWG rate (kg/week) in accordance with NAM guidelines. GWG z-scores were generated using the INTEGROWTH-21 and US standards to account for differing lengths of gestation. Birth outcome data were obtained from medical records. Associations of GWG z-score with adverse birth outcomes were assessed using multivariable linear or log-binomial regression. RESULTS: Among 292 participants (48% WHIV), median age was 29 years (IQR, 25-33), median pre-pregnancy body mass index (BMI) was 31 kg/m2 (IQR, 26-36) and 20% were primiparous at baseline. The median weekly rate of GWG was 0.30 kg/week (IQR, 0.12-0.50), 35% had GWG below NAM standards (59% WHIV) and 48% had GWG above NAM standards (36% WHIV). WHIV gained weight more slowly (0.25 vs. 0.37 kg/week, p<0.01) than women without HIV. Weekly rate of GWG did not differ by ART regimen (DTG-based ART 0.25 vs. efavirenz-based ART 0.27 kg/week, p = 0.80). In multivariable analyses, GWG z-score was positively associated with continuous birth weight (mean difference = 68.53 95% CI 8.96, 128.10) and categorical high birth weight of >4000 g (RR = 2.18 95% CI 1.18, 4.01). CONCLUSIONS: Despite slower GWG among WHIV, nearly half of all women gained weight faster than recommended by the NAM. GWG was positively associated with infant birth weight. Interventions to support healthy GWG in sub-Saharan Africa are urgently needed.

POSITION: The Society for Maternal-Fetal Medicine supports the right of all individuals to access the full spectrum of reproductive health services, including abortion care. Reproductive health decisions are best made by each individual with guidance and support from their healthcare providers. The Society opposes legislation and policies that limit access to abortion care or criminalize abortion care and self-managed abortion. In addition, the Society opposes policies that compromise the patient-healthcare provider relationship by limiting a healthcare provider's ability to counsel patients and provide evidence-based, medically appropriate treatment.

Background: The cardiometabolic impact of HIV infection and treatment with antiretroviral therapy (ART) in pregnancy and the postpartum period remains unclear. Methods: We enrolled pregnant persons with (PHIV) and without HIV in Cape Town, South Africa, who were ≥18 years old at 24-28 weeks' gestation and followed them up to 32 months postpartum. We estimated associations between HIV status and cardiometabolic risk including body mass index (BMI), obesity (BMI ≥30â kg/m2), blood pressure (BP; elevated systolic BP ≥130 and/or diastolic ≥85â mmHg), lipid levels, and metabolic syndrome according to the Joint Interim Statement criteria using multivariable log binomial or linear regression models. Subgroup analyses compared PHIV on efavirenz (EFV)- vs dolutegravir (DTG)-based ART. Results: Among 400 participants (n = 200 without HIV, n = 200 PHIV), 52% had prepregnancy obesity and 9% had elevated BP. Postpartum, 57% were classified with obesity, 31% had elevated BP, and 29% had metabolic syndrome. In multivariable analyses, HIV was associated with a lower BMI prepregnancy but not postpartum; however, mean indices were in the obese range regardless of HIV status. Neither BMI nor obesity prepregnancy or postpartum differed by ART regimen. Among PHIV, participants on DTG had higher levels of elevated BP in pregnancy and postpartum, compared with PHIV on EFV. Conclusions: We observed high levels of obesity, elevated BP, and metabolic syndrome in the perinatal period but few differences by HIV status. Participants on DTG may be more likely to have elevated BP in pregnancy and postpartum. Monitoring of cardiometabolic health for pregnant persons on DTG is warranted.
RESUMO
OBJECTIVE: To compare the rates of death or survival with severe neurodevelopmental impairment (sNDI) at 2 years among extremely preterm infants in relation to pre-pregnancy or first-trimester maternal body mass index (BMI). METHODS: This retrospective cohort study included extremely preterm infants (gestational age 220/7-266/7 weeks). The study was conducted at National Institute of Child Health and Human Development Neonatal Research Network sites. The primary outcome was death or sNDI at 2 years. RESULTS: Data on the primary outcome were available for 1208 children. Death or sNDI was not different among the three groups: 54.9% in normal, 56.1% in overweight, and 53.4% in obese group (p = 0.39). There was no significant difference in mortality, sNDI, moderate/severe cerebral palsy, Bayley Scales of Infant Development (BSID)-III cognitive composite score <70, BSID-III language composite score <70 in adjusted models. CONCLUSION: Neurodevelopmental outcome was not significantly associated with maternal pre-pregnancy BMI among extreme preterm infants.

OBJECTIVE: Resilience is associated with mental and somatic health benefits. Given the social, physical, and mental health toll of the coronavirus disease 2019 (COVID-19) pandemic, we examined whether the COVID-19 pandemic was associated with population-level changes in resilience among pregnant people. STUDY DESIGN: Secondary analysis of a prospective cohort of nulliparous pregnant people <20 weeks' gestation from a single hospital. Participants completed baseline assessments of resilience characteristics, including dispositional optimism (DO), mindfulness, and proactive coping. For this analysis, participants recruited before the COVID-19 pandemic were compared with those recruited during the pandemic. The primary outcome was DO, assessed as a continuous score on the validated Revised Life Orientation Test. Secondary outcomes included continuous scores on mindfulness and proactive coping assessments. Bivariable analyses were completed using chi-squared and Mann-Whitney U tests. Multivariable linear regression compared resilience scores by recruitment time frame, controlling for confounders selected a priori: maternal age, education, and marital status. RESULTS: Of the 300 participants, 152 (50.7%) were recruited prior to the pandemic. Demographic and pregnancy characteristics differed between groups: the during-pandemic group was older, had higher levels of education, and were more likely to be married/partnered. There were no significant differences in any of the resilience characteristics before versus during the pandemic in bivariable or multivariable analyses. CONCLUSION: In this cohort, there were no differences in early pregnancy resilience characteristics before versus during the COVID-19 pandemic. This affirms that on a population level, resilience is a stable metric, even in the setting of a global pandemic. KEY POINTS: · Resilience is associated with mental and somatic health benefits.. · No difference in early-pregnancy resilience in those recruited before versus during the pandemic.. · Consistent with conceptualization of resilience as an innate characteristic..
RESUMO
OBJECTIVE: We aimed to evaluate uptake of the glucose tolerance test performed during delivery hospitalization as part of routine clinical care. STUDY DESIGN: This is a retrospective cohort study of people with GDM at a tertiary center. We collected 9 months of postimplementation data after the in-hospital ("early") glucose tolerance test was adopted as a routine screening option. Adherence was compared between those who elected early glucose tolerance testing versus those who deferred testing to the standard postpartum period. Bivariable statistics including demographics, care team, and postpartum testing/visit attendance were compared between those who received early testing and those who did not using chi-square, Fisher's exact, and t-tests. RESULTS: A total of 681 patients with GDM delivered during the study period. Of those who had an early glucose tolerance test ordered (n = 408), 340 (83.3%) completed the test. Among those who did not complete an early glucose tolerance test (ordered and not completed or never ordered), only 104/341 (30.5%) completed any postpartum glucose testing in the first 12 months of postpartum. There were significant differences in characteristics in terms of race/ethnicity, insurance, type of gestational diabetes (A1GDM vs. A2GDM), diabetes medications, obstetric care provider, and delivery mode. Among those who completed early testing, 43.7% of participants had impaired glucose metabolism and 6.5% had values concerning for overt diabetes mellitus. Among those who deferred testing to the standard 6- to 12-week period, 24.0% had impaired glucose metabolism and none had overt diabetes. Those who completed an early glucose tolerance test had a lower rate of postpartum visit attendance compared with those who deferred (75.6 vs. 91.5%, p < 0.01). CONCLUSION: In this cohort, when the early glucose tolerance test is offered in clinical practice, adherence rates are higher than when the test is deferred until the postpartum visit. KEY POINTS: · Adherence rates with the early glucose tolerance test (GTT) are higher than if the testing is deferred.. · Those who completed an early GTT had a lower rate of postpartum visit attendance compared with those who deferred.. · Offering an in-hospital postpartum GTT can help address low rates of glucose testing postpartum..

Food and nutrition-related factors, including foods and nutrients consumed, dietary patterns, use of dietary supplements, adiposity, and exposure to food-related environmental contaminants, have the potential to impact semen quality and male and female fertility; obstetric, fetal, and birth outcomes; and the health of future generations, but gaps in evidence remain. On 9 November 2022, Tufts University's Friedman School of Nutrition Science and Policy and the school's Food and Nutrition Innovation Institute hosted a 1-d meeting to explore the evidence and evidence gaps regarding the relationships between food, nutrition, and fertility. Topics addressed included male fertility, female fertility and gestation, and intergenerational effects. This meeting report summarizes the presentations and deliberations from the meeting. Regarding male fertility, a positive association exists with a healthy dietary pattern, with high-quality evidence for semen quality and lower quality evidence for clinical outcomes. Folic acid and zinc supplementation have been found to not impact male fertility. In females, body weight status and other nutrition-related factors are linked to nearly half of all ovulation disorders, a leading cause of female infertility. Females with obesity have worse fertility treatment, pregnancy-related, and birth outcomes. Environmental contaminants found in food, water, or its packaging, including lead, perfluorinated alkyl substances, phthalates, and phenols, adversely impact female reproductive outcomes. Epigenetic research has found that maternal and paternal dietary-related factors can impact outcomes for future generations. Priority evidence gaps identified by meeting participants relate to the effects of nutrition and dietary patterns on fertility, gaps in communication regarding fertility optimization through changes in nutritional and environmental exposures, and interventions impacting germ cell mechanisms through dietary effects. Participants developed research proposals to address the priority evidence gaps. The workshop findings serve as a foundation for future prioritization of scientific research to address evidence gaps related to food, nutrition, and fertility.

BACKGROUND: Gestational diabetes mellitus (GDM) has been rising in the United States, and it poses significant health risks to pregnant individuals and their infants. Prior research has shown that individuals with GDM also experience prevalent stress and mental health issues, which can further contribute to glucose regulation difficulties. Stigma associated with GDM may contribute to these mental health challenges, yet there is a lack of focused research on GDM-related stigma, its impact on psychological health, and effective coping mechanisms. Thus, this qualitative study aims to understand individuals' experiences related to GDM stigma, mental health, and facilitative coping. METHODS: In-depth, semi-structured interviews were conducted with 14 individuals with a current or recent (within the last year) diagnosis of GDM. Thematic analysis was employed to guide data analysis. RESULTS: Four themes emerged from data analysis: (1) experience of distal GDM stigma including stigmatizing provider interactions, stigma from non-medical spaces, and intersecting stigma with weight, (2) internalized GDM stigma, such as shame, guilt, and self-blame, (3) psychological distress, which included experiences of stress and overwhelm, excessive worry and fear, and loneliness and isolation, and (4) facilitative coping mechanisms, which included diagnosis acceptance, internet-based GDM community, active participation in GDM management, social and familial support, and time for oneself. CONCLUSIONS: Findings demonstrate the relevance of GDM stigma in mental health among people with GDM and the need for addressing GDM stigma and psychological health in this population. Interventions that can reduce GDM stigma, improve psychological wellness, and enhance positive coping may facilitate successful GDM management and healthy birth outcomes. Future quantitative, theory-driven research is needed to understand the prevalence of GDM stigma experiences and mechanisms identified in the current study, as well as among marginalized populations (e.g., individuals of color, sexual and gender minorities).

BACKGROUND: Dispositional optimism, the expectation of positive outcomes after personal challenges, is a resilience factor associated with widespread health benefits. However, the data on pregnancy-related outcomes are more limited. OBJECTIVE: This study aimed to assess the association of early pregnancy dispositional optimism with adverse perinatal outcomes. STUDY DESIGN: This was a prospective cohort study completed between May 2019 and February 2022 at a single, large tertiary medical center. Nulliparous pregnant people were recruited from outpatient obstetrical care sites. Participants completed a validated assessment of dispositional optimism at <20 weeks of gestation and were followed up until delivery. The primary outcome was an adverse maternal outcome composite that included gestational diabetes mellitus, hypertensive disorders of pregnancy, and/or cesarean delivery. The secondary outcomes included individual composite components and a neonatal morbidity composite. Bivariate analyses compared characteristics and primary and secondary outcomes by dispositional optimism score quartile. Multivariable logistic regression compared outcomes by dispositional optimism score quartile with the highest quartile serving as the referent, controlling for confounders determined a priori. RESULTS: Overall, 491 pregnant people were approached for participation, and 135 pregnant people (27.5%) declined participation. Among the 284 individuals who enrolled and had complete outcome data, the median dispositional optimism score was 16.0 (interquartile range, 14-18), and 47.9% of individuals experienced at least 1 adverse maternal outcome 135 (47.9%). After adjusting for confounders, the odds of adverse maternal outcomes were significantly higher in the lowest 2 optimism quartiles: quartile 1 (adjusted odds ratio, 3.33; 95% confidence interval, 1.57-7.36) and quartile 2 (adjusted odds ratio, 2.22; 95% confidence interval, 1.05-4.79) than the highest quartile. This was driven by significantly higher rates of hypertension (quartile 1: adjusted odds ratio, 2.62; 95% confidence interval, 1.12-6.29) and cesarean delivery (quartile 1: adjusted odds ratio, 2.75; 95% confidence interval, 1.20-6.55). There was no difference noted when quartile 3 was compared with quartile 4. CONCLUSION: Lower early pregnancy dispositional optimism was associated with significantly higher odds of adverse maternal outcomes. Interventions targeting improvements in optimism may be a novel mechanism for reducing perinatal morbidity.

OBJECTIVE: To estimate associations of HIV status and antiretroviral (ART) regimen with gestational diabetes (GDM) and postpartum glucose metabolism. DESIGN: Prospective cohort study. METHODS: We enrolled pregnant persons with HIV (PWH) and without HIV in Cape Town, South Africa who were at least 18âyears of age at 24-28âweeks' gestation and followed up to 26âmonths postpartum. Participants were tested for GDM in pregnancy and for diabetes postpartum using a 75âg 2âh oral glucose tolerance test (OGTT) and diagnosed via WHO criteria. We estimated associations of HIV status and ART regime [efavirenz (EFV) versus dolutegravir (DTG)] with GDM and postpartum impaired glucose metabolism using multivariable log binomial or linear regression models. RESULTS: Among 397 participants [median age 30 (interquartile range (IQR) 25-34; n â=â198 without HIV, n â=â199 PWH], the prevalence of GDM was 6% (9 PWH versus 3% without HIV). In multivariable analyses, PWH were at higher risk of GDM [risk ratio (RR) 3.9, 95% confidence interval (CI) 1.4-10.7] after adjustment for prepregnancy BMI and other confounders. GDM risk did not differ by ART regimen (unadjusted prevalence 8.1% DTG versus 5.6% EFV, adjusted RR 1.1, 95% CI 0.2-6.6). Few participants had diabetes, impaired glucose tolerance (IGT), or impaired fasting glucose postpartum ( n â=â13, 6%) with no differences by HIV or ART status. CONCLUSION: In a setting of universal GDM testing, PWH had an increased risk of impaired glucose metabolism during pregnancy but not postpartum. Among PWH, GDM risk was similar regardless of EFV or DTG use. Given concerns about DTG and weight gain, diabetes risk should continue to be monitored.

The objective of this study is to evaluate if proximity to food sources, rather than density, is associated with gestational diabetes mellitus (GDM) risk. Rhode Island birth certificate data from 2015-2016 were utilized. A proximity analysis was used to determine the distance from each pregnant person's home address to the closest food source (fast food restaurant, supermarket, and farmers market/community garden). Multivariable logistic regression was used to examine the association between distance to food source and the risk of GDM. Of the 20,129 births meeting inclusion criteria, 7.2% (1,447) had GDM. Distance to food sources differed by insurance type, educational background, and race/ethnicity. There was no statistically significant association between distance to any of the food sources and GDM in the adjusted model. Other factors need to be examined to improve interventions, influence policy, and impact neonatal and maternal outcomes.

BACKGROUND: Prediction models have shown promise in helping clinicians and patients engage in shared decision-making by providing quantitative estimates of individual risk of important clinical outcomes. Gestational diabetes mellitus is a common complication of pregnancy, which places patients at higher risk of primary CD. Suspected fetal macrosomia diagnosed on prenatal ultrasound is a well-known risk factor for primary CD in patients with gestational diabetes mellitus, but tools incorporating multiple risk factors to provide more accurate CD risk are lacking. Such tools could help facilitate shared decision-making and risk reduction by identifying patients with both high and low chances of intrapartum primary CD. OBJECTIVE: This study aimed to develop and internally validate a multivariable model to estimate the risk of intrapartum primary CD in pregnancies complicated by gestational diabetes mellitus undergoing a trial of labor. STUDY DESIGN: This study identified a cohort of patients with gestational diabetes mellitus derived from a large, National Institutes of Health-funded medical record abstraction study who delivered singleton live-born infants at ≥34 weeks of gestation at a large tertiary care center between January 2002 and March 2013. The exclusion criteria included previous CD, contraindications to vaginal delivery, scheduled primary CD, and known fetal anomalies. Candidate predictors were clinical variables routinely available to a practitioner in the third trimester of pregnancy found to be associated with an increased risk of CD in gestational diabetes mellitus. Stepwise backward elimination was used to build the logistic regression model. The Hosmer-Lemeshow test was used to demonstrate goodness of fit. Model discrimination was evaluated via the concordance index and displayed as the area under the receiver operating characteristic curve. Internal model validation was performed with bootstrapping of the original dataset. Random resampling with replacement was performed for 1000 replications to assess predictive ability. An additional analysis was performed in which the population was stratified by parity to evaluate the model's predictive ability among nulliparous and multiparous individuals. RESULTS: Of the 3570 pregnancies meeting the study criteria, 987 (28%) had a primary CD. Of note, 8 variables were included in the final model, all significantly associated with CD. They included large for gestational age, polyhydramnios, older maternal age, early pregnancy body mass index, first hemoglobin A1C recorded in pregnancy, nulliparity, insulin treatment, and preeclampsia. Model calibration and discrimination were satisfactory with the Hosmer-Lemeshow test (P=.862) and an area under the receiver operating characteristic curve of 0.75 (95% confidence interval, 0.74-0.77). Internal validation demonstrated similar discriminatory ability. Stratification by parity demonstrated that the model worked well among both nulliparous and multiparous patients. CONCLUSION: Using information routinely available in the third trimester of pregnancy, a clinically pragmatic model can predict intrapartum primary CD risk with reasonable reliability in pregnancies complicated by gestational diabetes mellitus and may provide quantitative data to guide patients in understanding their individual primary CD risk based on preexisting and acquired risk factors.

INTRODUCTION: Despite efforts to improve postpartum health care in the United States, little is known about patterns of postpartum care beyond routine postpartum visit attendance. This study aimed to describe variation in outpatient postpartum care patterns. METHODS: In this longitudinal cohort study of national commercial claims data, we used latent class analysis to identify subgroups of patients (classes) with similar outpatient postpartum care patterns (defined by the number of preventive, problem, and emergency department outpatient visits in the 60 days after birth). We also compared classes in terms of maternal sociodemographics and clinical characteristics measured at childbirth, as well as total health spending and rates of adverse events (all-cause hospitalizations and severe maternal morbidity) measured from childbirth to the late postpartum period (61-365 days after birth). RESULTS: The study cohort included 250,048 patients hospitalized for childbirth in 2016. We identified six classes with distinct outpatient postpartum care patterns in the 60 days after birth, which we classified into three broad groups: no care (class 1 [32.4% of the total sample]); preventive care only (class 2 [18.3%]); and problem care (classes 3-6 [49.3%]). The prevalence of clinical risk factors at childbirth increased progressively from class 1 to class 6; for example, 6.7% of class 1 patients had any chronic disease compared with 15.5% of class 5 patients. Severe maternal morbidity was highest among the high problem care classes (classes 5 and 6): 1.5% of class 6 patients experienced severe maternal morbidity in the postpartum period and 0.5% in the late postpartum period, compared with less than 0.1% of patients in classes 1 and 2. CONCLUSIONS: Efforts to redesign and measure postpartum care should reflect the current heterogeneity in care patterns and clinical risks in the postpartum population.

OBJECTIVE: Waterpipe tobacco (WPT) use is common among reproductive age patients and is often perceived as safer than cigarette use. Prior studies have shown a decrease in nausea and vomiting symptoms among pregnant women who use cigarettes, but no studies to date have examined these symptoms in pregnant women who use WPT. This study was aimed to investigate the extent of symptoms of nausea/vomiting of pregnancy among participants who self-reported WPT use during pregnancy. STUDY DESIGN: Secondary analysis of a prospective cohort study examining WPT use during pregnancy. Participants completed the Pregnancy-Unique Quantification of Emesis (PUQE) during first and third trimesters. Medical conditions were determined by medical record review. Participants were evaluated by sole WPT use versus dual/polysubstance WPT use and frequency of WPT use. RESULTS: Ninety-nine (100%) participants completed the PUQE questionnaire during first trimester and 82 (82.8%) completed the PUQE during third trimester. Almost all (91.9%) participants reported moderate nausea/vomiting symptoms at both assessments. There was no difference in frequency of WPT use in pregnancy or rates of dual/polysubstance WPT use in participants with all levels of the PUQE questionnaire. There was also no difference in rates of WPT use or PUQE scores between sole WPT users and dual/polysubstance users. When comparing low and high WPT use, those who were in the higher frequency use group had higher waterpipe dependence scale scores (7.2 vs. 5.3, p < 0.02). With regard to maternal medical comorbidities, the only difference between groups was that sole WPT users were more likely to have a diagnosis of asthma than dual/polysubstance users (36.8 vs. 14.9%, p < 0.02). CONCLUSION: There were no differences in symptoms of nausea and vomiting of pregnancy or medical conditions in pregnant women who use WPT with any frequency during pregnancy. However, sole WPT users had higher rates of asthma than dual/polysubstance WPT users. KEY POINTS: · Waterpipe tobacco use is one of the most common forms of tobacco use among reproductive age patients.. · Waterpipe tobacco use was not associated with any changes in nausea/vomiting of pregnancy symptoms.. · Future research on the use of waterpipe tobacco in pregnancy can aid in public health responses..

OBJECTIVE: Evaluate if odds of survival without major morbidity are higher among extremely low gestation neonates (ELGANs) born to mothers with chronic hypertension (cHTN) or hypertensive disorders of pregnancy (HDP) compared to ELGANs born to mothers without hypertension (HTN). STUDY DESIGN: Retrospective study of prospectively collected data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Included children had a birthweight of 401-1000 g and/or gestational age of 220/7 to 286/7 wks. The primary outcome was survival to discharge without major morbidity. Multivariable regression models were used to compare outcomes among ELGANs born to women with cHTN, HDP, and no HTN. RESULTS: Survival without morbidities for newborns of mothers with no HTN, cHTN and HDP (29.1%, 32.9%, 37.0% respectively) did not differ after adjustment. CONCLUSION: After adjusting for contributing variables maternal HTN is not associated with improved survival free of morbidity among ELGANs. TRIALS REGISTRATION: clinicaltrials.gov Identifier: NCT00063063 (generic database).

OBJECTIVES: To evaluate third-grade reading and math proficiency for children born to adolescent women compared with those born to non-adolescent women. METHODS: A statewide, retrospective cohort study was conducted in Rhode Island using third-grade year-end examination data from 2014 to 2017 as part of a statewide initiative to improve third grade reading levels. Children's third-grade reading and math proficiencies were compared between those born to nulliparous adolescent women (age 15-19 at the time of delivery), and nulliparous women 20 years or older at delivery. Bivariate analyses were conducted to compare maternal and child characteristics between adolescent and non-adolescent groups. Multivariable logistic regression was used to examine the association between having an adolescent mother and being proficient in reading and math after adjusting for lunch subsidy, core city residence, child race/ethnicity and sex. RESULTS: Of the 8,248 children meeting the inclusion criteria, 20% were born to adolescent women and the remaining 80% were born to non-adolescent women. After adjusting for potential confounders, children born to adolescent women were significantly less likely to be proficient in both reading (adjusted risk ratio (aRR) 0.77, 95% confidence interval (CI): 0.71-0.83) and math (aRR 0.78, 95% CI: 0.72-0.85). CONCLUSIONS FOR PRACTICE: Children born to adolescent women had significantly lower rates of reading and math proficiency when compared with children of non-adolescent women. These children may benefit from additional resources focused on early academic performance in order to address disparities in reading and math proficiency.
