Racial Disparities in Breastfeeding Rates in Patients with Heart Disease.

OBJECTIVE: To evaluate racial disparities in breastfeeding rates in patients with heart disease. STUDY DESIGN: Retrospective cohort of pregnant patients with maternal cardiac disease managed by a Cardio-Obstetrics program. Patients self-identifying as Non-Hispanic Black (NHB) and Non-Hispanic White (NHW), who attended ≥ 1 prenatal visit at the Cardio-Obstetrics Program and delivered at the same hospital between March 2015 and June 2019 were included. The primary outcome was breastfeeding rate at discharge from the delivery-associated hospitalization. Secondary outcomes included breastfeeding intent on admission and breastfeeding rates at the postpartum visit among patients who initiated breastfeeding. RESULTS: 138 pregnant patients with cardiac disease were included: 58 (42%) NHB and 80 (58%) NHW patients. Parity, marital status and insurance were statistically different between groups. NHB patients were more likely to have government insurance compared to NHW patients (77.6% vs. 40%; p < 0.001). There was a significant difference in the intent to breastfeed upon admission for the delivery-associated hospitalization (74.2% NHB vs. NHW 91.3%; p = 0.01), but not at hospital discharge (84.5% NHB vs. 93.8% NHW; p = 0.08). However, breastfeeding rates were significantly lower among NHB patients at the postpartum visit among the entire cohort (38.2% in NHB vs. 61.1% in NHW women; p = 0.036) and among those who initiated breastfeeding (35.3% NHB vs. 61.1% NHW, p = 0.018). CONCLUSIONS: Despite similar breastfeeding rates at hospital discharge, NHB patients with maternal cardiac disease were less likely to intend to breastfeed at admission and/or continue breastfeeding by the postpartum visits. Qualitative studies understanding these differences are crucial to improve breastfeeding rates, especially for NHB patients with maternal cardiac disease.

Breastfeeding Practices in Patients with Heart Disease Stratified by Area Deprivation Index.

Objective: We sought to evaluate breastfeeding (BF) practices in patients with maternal cardiac disease (MCD) stratified by area deprivation index (ADI) to identity communities at risk. Study Design: Retrospective cohort of patients managed by the University of Alabama at Birmingham (UAB) Cardio-Obstetrics Program. Patients were included if they had ≥1 prenatal visit with the Cardio-Obstetrics team, delivered at UAB, and had a street address on file. The primary outcome was BF rate at hospital discharge. Secondary outcomes included BF intent on admission and BF at the postpartum (PP) visit. ADI reports socioeconomic disadvantage at the census tract level; 1 = least deprived and 100 = most deprived. Baseline characteristics and BF rates were compared by ADI categories: Low (ADI 1-33), medium (ADI 34-66), and high (ADI 67-100). Results: One hundred and forty-eight patients were included: 14 (10%) low, 42 (28%) medium, and 92 (62%) high ADI. Patients in the high ADI category were younger relative to those in the medium or low ADI (26 versus 28 versus 32 years; p < 0.01) and less likely to be married or living with a partner (30.4% versus 58.5% versus 71.4%; p < 0.01), There was no difference in BF intent between the lowest, medium, and highest ADI categories (85.7% versus 85.4% versus 81.6%; p = 0.38) or BF rates at hospital discharge (100% versus 92.7% versus 85.6%, p = 0.23). However, there was a significant difference in BF rates at the PP visit (90% versus 63.0% versus 38.6%; p < 0.01) even after controlling for differences in baseline characteristics (odds ratio = 0.11 (95% confidence interval [0.01-0.93]), p = 0.043). Conclusions: There was an association between living in a resource-poor community and early cessation of BF in our population of patients with MCD. Community-based interventions targeting mothers with heart disease living in high ADI communities may help these individuals achieve higher BF rates.

Outcomes in low-risk patients before and after an institutional policy offering 39-week elective induction of labor.

OBJECTIVE: Elective induction of labor versus expectant management at 39 weeks gestation in low-risk nulliparous patients was shown in the ARRIVE randomized trial of over 6000 patients to decrease risks of cesarean delivery without significant change in the composite perinatal outcome. We aimed to pragmatically analyze the effect of offering elective induction of labor (eIOL) to all low-risk patients. METHODS: Retrospective cohort study of low-risk nulliparous and multiparous patients delivering live, non-anomalous singletons at a single center at greater than or equal to 39 0/7 weeks gestational age. Those with prior or planned cesarean delivery, ruptured membranes, medical comorbidities, or contraindications to vaginal delivery were excluded. Patients were categorized as before (pre-eIOL; 1/2012-3/2014) or after (post-eIOL; 3/2019-12/2021) an institution-wide policy offering eIOL at 39 0/7 weeks. Births occurring April 2014 to December 2018 were allocated to a separate cohort (during-eIOL) given increased exposure to eIOL as our center recruited participants for the ARRIVE trial. The primary outcome was cesarean birth. Secondary outcomes included select maternal (e.g. chorioamnionitis, operative delivery, postpartum hemorrhage) and neonatal morbidities (e.g. birthweight, small- and large-for gestational age, hypoglycemia). Characteristics and outcomes were compared between the pre and during-eIOL, and pre and post-eIOL groups; adjusted OR (95% CI) were calculated using multivariable regression. Subgroup analysis by parity was planned. RESULTS: Of 10,758 patients analyzed, 2521 (23.4%) were pre-eIOL, 5410 (50.3%) during-eIOL, and 2827 (26.3%) post-eIOL. Groups differed with respect to labor type, age, race/ethnicity, marital and payor status, and gestational age at care entry. Post-eIOL was associated with lower odds of cesarean compared to pre-eIOL (aOR 0.83 [95% CI 0.72-0.96]), which was even lower among those specifically undergoing labor induction (aOR 0.58 [0.48-0.70]. During-eIOL was also associated with lower odds of cesarean compared to pre-eIOL (aOR 0.79 [0.69-0.90]). Both during and post-eIOL groups were associated with higher odds of chorioamnionitis, operative delivery, and hemorrhage compared to pre-eIOL. However, only among post-eIOL were there fewer neonates weighing ≥4000 g, large-for-gestational age infants, and neonatal hypoglycemia compared to pre-IOL. CONCLUSION: An institutional policy offering eIOL at 39 0/7 to low-risk patients was associated with a lower cesarean birth rate, lower birthweights and lower neonatal hypoglycemia, and an increased risk of chorioamnionitis and hemorrhage.

Breastfeeding practices among patients managed by a comprehensive cardio-obstetrics program.

Objective: To evaluate breastfeeding intent, rates at discharge, and continued breastfeeding at follow-up in patients managed in a comprehensive cardio-obstetrics program stratified by severity of maternal cardiac disease.Study Design: Retrospective cohort of patients managed by a comprehensive cardio-obstetrics program at the University of Alabama at Birmingham (UAB). Patients were included if they had ≥1 prenatal visit with the Cardio-Obstetrics team and delivered at UAB. The primary outcome was the breastfeeding rate on discharge from the delivery-associated hospitalization. Secondary outcomes included intent to breastfeed on admission and breastfeeding at the postpartum visit. Baseline characteristics and rates were compared between patients with less severe (mWHO I - II/III) vs. more severe (mWHO III - IV) maternal cardiac disease.Results: 147 patients were included: 85 (57.8%) mWHO class I - II and 62 (42.2%) mWHO class III-IV. Patients with more severe maternal cardiac disease had higher rates of chronic hypertension (22.6% vs. 9.4%; p = 0.027), lower gestational age at delivery (36.4 vs 37.7 weeks; p = 0.008), and higher rates of NICU admission (31.2% vs. 14.1%; p = 0.013). There were no significant differences between mWHO class I-II vs. mWHO class III-IV in intent to breastfeed upon admission to the delivery-associated hospitalization (84.7% vs. 82.3%; p = 0.67), breastfeeding rates upon discharge from the delivery-associated hospitalization (90.6% vs. 87.1%; p = 0.50), or breastfeeding rates at the postpartum visit (54.1% vs. 48.5%; p = 0.60).Conclusions: Despite potential barriers in this high-risk population, over 85% of patients breastfed upon discharge from the delivery-associated hospitalization. However, breastfeeding rates dropped by 40% at the postpartum visit. Strategies to support breastfeeding in the post-partum period in patients with maternal cardiac disease are imperative.

Validation of a Remote Monitoring Blood Pressure Device in Pregnancy.

BACKGROUND: The Ideal Life Blood Pressure Manager measures blood pressure (BP) and automatically transmits results to the patient's medical record independent of internet access, but has not been validated. Our objective was to conduct a validation study of the Ideal Life BP Manager in pregnant women using a validation protocol. METHODS: Pregnant participants were enrolled into three subgroups per the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization protocol: normotensive (systolic blood pressure (SBP) < 140 and diastolic blood pressure (DBP) < 90), hypertensive without proteinuria (SBP ≥ 140 or DBP ≥ 90), and preeclampsia (SBP ≥ 140 or DBP ≥ 90 with proteinuria). Two trained research staff used a mercury sphygmomanometer to validate the device, alternating sphygmomanometer, and device readings for a total of 9 measurements. RESULTS: Among 51 participants, the mean SBP and DBP differences and standard deviations between the device and the mean staff measurements for all participants were 1.7 ± 7.1 and 1.5 ± 7.0 mm Hg, respectively. The standard deviations of the individual participant's paired device and mean staff SBP and DBP measurements were 6.0 and 6.4 mm Hg, respectively. The device was more likely to overestimate rather than underestimate BP (SBP: mean difference = 1.67, 95% CI [-12.15 to 15.49]; DBP: mean difference = 1.51, 95% CI [-12.26 to 15.28]). Most paired readings had a difference of less than 10 mm Hg across averaged paired readings. CONCLUSION: The Ideal Life BP Manager met internationally recognized validity criteria in this sample of pregnant women.

Progression to Severe Chronic Hypertension 5-7 Years After a Pregnancy With Mild Chronic Hypertension.

OBJECTIVE: To estimate the incidence of severe chronic hypertension (cHTN) within 5-7 years after a pregnancy complicated by mild cHTN. METHODS: This was a retrospective cohort study of women with mild cHTN during an index pregnancy between 2012 and 2014. Women were included if they received prenatal care at a single academic center and had mild cHTN during their pregnancy. Women with severe cHTN, type 1 diabetes, systemic lupus erythematosus, cardiomyopathy, proteinuria, or creatinine level greater than 1.1 mg/dL before 23 weeks of gestation at baseline were excluded. The primary outcome was a composite of severe cHTN (defined as new-onset of two or more severe blood pressures) or new-onset cardiovascular disease complications more than 12 weeks after the index delivery. RESULTS: A total of 647 women with mild cHTN met inclusion criteria. Of these, 236 (36.5%, 95% CI 32.8-40.2%) women experienced the primary composite outcome of severe cHTN within 5-7 years of the index pregnancy. Black women progressed more rapidly than White women (adjusted hazard ratio [aHR] 1.99, 95% CI 1.43-2.76). Smoking tobacco was also associated with more rapid progression to severe cHTN (aHR 1.47, 95% CI 1.13-1.90). CONCLUSION: In this cohort, one in three women with mild cHTN in an index pregnancy progressed to severe cHTN within 5-7 years. Prospective studies to validate this finding are needed.

Timing of Maternal Discharge after Cesarean Delivery and Risk of Maternal Readmission.

OBJECTIVE: Despite legislation and hospital policies (present in some institutions) mandating a minimum length of stay in an effort to decrease the frequency of hospital readmissions, the effectiveness of this approach remains uncertain.We hypothesized that following cesarean delivery (CD), the rates of maternal readmission or unscheduled health care visits are lower in patients discharged on postoperative day (POD) 3 or ≥4 as compared with those discharged earlier on POD 2. METHODS: This is a secondary analysis of a multicenter randomized trial comparing adjunctive azithromycin for unscheduled CD to prevent infection. Groups were compared based on the duration of hospitalization measured in days from delivery (POD 0) to day of discharge and categorized as POD 2, 3, and ≥4. The primary outcome was the composite of any maternal postpartum readmission, unscheduled clinic, or emergency room (ER) visit, within 6 weeks of delivery. Secondary outcomes included components of the primary outcome and neonatal readmissions. We excluded women with hypertensive disorders of pregnancy and infections diagnosed prior to POD 2. RESULTS: A total of 1,391 patients were included. The rate of the primary outcome of any readmission increased with POD at discharge: 5.9% for POD 2, 9.4% for POD 3, and 10.9% for POD ≥4 group (trend for p = 0.03). The primary outcome increased with later discharge (POD ≥4 when compared with POD 2). Among components of the composite, ER and unscheduled clinic visits, but not maternal readmissions, increased with the timing of discharge for patients discharged on POD ≥4 when compared with POD 2. Using logistic regression, discharge on POD 3 and on POD ≥4 was significantly associated with the composite (adjusted odds ratios [aOR] 2.6, 95% confidence interval [CI] [1.3-5.3]; aOR 2.9, 95% CI [1.3-6.4], respectively) compared with POD 2. CONCLUSION: The risk of maternal readmission composite following uncomplicated but unscheduled CD was not lower in patients discharged home on POD 3 or ≥4 compared with patients discharged earlier (POD 2). KEY POINTS: · Risk of maternal readmission is higher in patients discharged on POD 3 or 4 compared with POD 2.. · No significant differences by the timing of discharge were observed for any neonatal readmissions.. · Timing of discharge should include an individualized approach with the option of discharge by POD 2..

An evaluation of seasonal maternal-neonatal morbidity related to trainee cycles.

BACKGROUND: The existence of the "July phenomenon" (worse outcomes related to the presence of new physician trainees in teaching hospitals) has been debated in the literature and media. Previous studies of the phenomenon in obstetrics are limited by the quality and detail of data. OBJECTIVE: To evaluate whether the months of June to August, when transitions in trainees occur, are associated with increased maternal and neonatal morbidity. STUDY DESIGN: Secondary analysis of an observational cohort of 115,502 mother-infant pairs that delivered at 25 hospitals from March 2008 to February 2011. Inclusion criteria were an individual who had a singleton, nonanomalous live fetus at the onset of labor, and delivered at a hospital with trainees. The primary outcomes were composites of maternal and neonatal morbidity. We evaluated the outcomes by academic quarter during which the delivery occurred, beginning July 1, and by duration of the academic year as a continuous variable. To account for clustering in outcomes at a given delivery location, we applied hierarchical logistic regression with adjustment for hospital as a random effect. RESULTS: Of 115,502 deliveries, 99,929 met the inclusion criteria. Race and ethnicity, insurance, body mass index, drug use, and the availability of 24/7 maternal-fetal medicine, anesthesia, and neonatology varied by quarter. In adjusted analysis, the frequency of the composite maternal and neonatal morbidity did not differ by quarter. No differences in composite morbidity were observed when using day of the year as a continuous variable (maternal morbidity adjusted odds ratio, 1.00; 95% confidence interval, 0.99-1.00 and neonatal morbidity adjusted odds ratio, 1.00; 95% confidence interval, 1.00-1.01) and after adjustment for hospital as a random effect. Odds of major surgical complications in quarter 2 were twice those in quarter 1. Neonatal injury and intensive care unit were less frequent in later quarters. CONCLUSION: Maternal and neonatal morbidity in teaching hospitals was not associated with the academic quarter during which delivery occurred, and there was no evidence of a "July phenomenon".

Racial disparities in reliable contraceptive use in women with heart disease.

OBJECTIVE: The aim of the study was to investigate the differences in reliable contraceptive use between black women and white women with maternal cardiac disease. METHODS: The study comprised a retrospective cohort of women with maternal cardiac disease managed by the University of Alabama at Birmingham (UAB) Comprehensive Pregnancy and Heart Program (CPHP). Women were included if they had attended one or more prenatal visits at the UAB CPHP and delivered at the UAB hospital between March 2015 and June 2019. The primary outcome was reliable contraceptive use within 2 months postpartum, defined by receipt of long-acting reversible contraception (i.e., an intrauterine contraceptive device or an etonogestrel implant) or female sterilisation. All outcomes were compared based on self-reported race. RESULTS: One hundred and forty-nine women met the inclusion criteria. Black women (n = 63) were more likely than white women (n = 86) to use reliable contraception (65% vs 43%; p = 0.008). Black women were less likely than white women to be undecided or decline contraception at the time of admission (13% vs 27%; p = 0.037). There was no difference in reliable contraceptive use between black women (n = 20, 63%) and white women (n = 23, 72%) with modified World Health Organisation (WHO) class III/IV lesions (p = 0.42). CONCLUSION: Black women with maternal cardiac disease were more likely than white women to receive reliable contraception. Interventions to prevent unintended pregnancy in women with maternal cardiac disease should focus on improving reliable contraceptive use, especially for women with modified WHO class III/IV lesions.

A systematic review of biomarkers associated with maternal infection in pregnant and postpartum women.

BACKGROUND: Serum biomarkers are commonly used to support the diagnosis of infection in non-pregnant patients whose clinical presentation suggests infection. The utility of serum biomarkers for infection in pregnant and postpartum women is uncertain. SEARCH STRATEGY: PubMed, CINAHL, EMBASE, ClinicalTrials.gov, Cochrane Library, CINAHL, and SCOPUS were searched from inception to February 2020. SELECTION CRITERIA: Full-text manuscripts in English were included if they reported the measurement of maternal serum biomarkers-and included a control group-to identify infection in pregnant and postpartum women. DATA COLLECTION AND ANALYSIS: two authors independently screened manuscripts, extracted data, and assessed methodologic quality. MAIN RESULTS: Interleukin-6 (IL-6), C-reactive protein, procalcitonin, insulin-like growth factor binding protein 1, tumor necrosis factor-α, calgranulin B, neopterin, and interferon-γ inducible protein 10 reliably indicated infection. Intercellular adhesion molecule 1, monocyte chemotactic and activating factor, soluble IL-6 receptor, and IL-8 were not useful markers in pregnant and postpartum women. CONCLUSIONS: Findings suggest that certain biomarkers have diagnostic value when maternal infection is suspected, but also confirms limitations in this population.

Value of HbA1c in Obese Women with Gestational Diabetes.

OBJECTIVE: We sought to assess the association of hemoglobin A1c (HbA1c) with adverse perinatal outcomes in obese women with gestational diabetes mellitus (GDM). STUDY DESIGN: This was a secondary analysis of a multicenter randomized controlled trial assessing early (14-20 weeks) versus routine (24-28 weeks) screening for GDM in obese women. Women were included if they were diagnosed with GDM at either time during pregnancy and had a HbA1c result available. The primary exposure was HbA1c at 24 to 28 weeks. The primary outcome was a composite of macrosomia, primary cesarean, pregnancy-induced hypertension, shoulder dystocia, neonatal hypoglycemia, or hyperbilirubinemia. Receiver operating characteristics (ROC) curves were used to assess the association of HbA1c with the composite outcome. The Liu method was used to select an optimal HbA1c cutoff, and the incidence of the outcome compared. RESULTS: Of 125 women with GDM, 93 (74%) had a HbA1c at 24 to 28 weeks and 103 (82.4%) had a HbA1c at 14 to 20 weeks. Baseline characteristics were balanced between groups above and below the cutoff. The area under the ROC curve for HbA1c and its association with the adverse perinatal composite outcome was 0.6 (95% confidence interval [CI]: 0.5-0.7). The frequency of the primary outcome was similar among women with low and high HbA1c at 24 to 28 weeks (adjusted relative risk, 1.12, 95% CI: 0.97-1.29). Compared with women with a decreasing HbA1c during pregnancy, women with a stable or increasing HbA1c did not have a significant increase in the primary adverse perinatal composite outcome. However, the frequency of preterm delivery was higher among women with stable or increasing HbA1c compared with those with a decreasing HbA1c (26.1 vs. 6.7%, p = 0.03). CONCLUSION: A single HbA1c in women with GDM is not associated with a composite perinatal adverse outcome, but a HbA1c that increases or remains stable between 14 to 20 and 24 to 28 weeks is associated with an increase in preterm delivery. KEY POINTS: · A single HbA1c in GDM is not associated with a composite perinatal adverse outcome.. · HbA1c that increases or remains stable may be associated with an increase in preterm delivery.. · HbA1c at 24 to 28 weeks was not significantly associated with the adverse perinatal composite outcome..

Association between Number of Prior Cesareans and Early Preterm Delivery in Women with Abnormal Placentation.

OBJECTIVE: Delivery timing at 34 to 36 weeks is nationally recommended for pregnancies complicated by placenta accreta spectrum (PAS). However, it has recently been suggested that those with ≥2 prior cesarean deliveries (CD) and PAS should be delivered earlier than 34 weeks because of a higher risk of unscheduled delivery and complications. We sought to evaluate whether the number of prior CD in women with PAS is associated with early preterm delivery (PTD) (<34 weeks). We also evaluated the same relationship in women with placenta previa alone (without PAS). STUDY DESIGN: This is a secondary analysis of a multicenter and observational study that included women with prior CD (maternal-fetal medicine unit cesarean registry). Women with a diagnosis of PAS (regardless of placenta previa) were included for our primary analysis, and women with known placenta previa (without a component of PAS) were independently analyzed in a second analysis. Two groups of patients from the registry were studied: patients with PAS (regardless of placenta previa) and patients with placenta previa without PAS. The exposure of interest was the number of prior CD: ≥2 CD compared with <2 CD. The primary outcome was PTD <34 weeks. Secondary outcomes included preterm labor requiring hospitalization or tocolysis, transfusion of blood products, composites of maternal and neonatal morbidities, and NICU admission. Outcomes by prior CD number groups were compared in both cohorts. Backward selection was used to identify parsimonious logistic regression models. RESULTS: There were 194 women with PAS, 97 (50%) of whom had <2 prior CD and 97 (50%) of whom had ≥2 prior CD. The rate of PTD <34 weeks in women with ≥2 prior CD compared with <2 in the setting of PAS was 23.7 versus 29.9%, p = 0.27; preterm labor requiring hospitalization was 24.7 versus 13.5%; p = 0.05. The rates of plasma transfusion were increased with ≥2 prior CD (29.9 vs. 17.5%, p = 0.04), but there were no differences in transfusion of other products or in composite maternal or neonatal morbidities. After multivariable adjustments, having ≥2 CDs was not associated with PTD <34 weeks in women with PAS (adjusted odds ratio (aOR): 0.73, 95% confidence interval [CI]: 0.39-13.8) despite an association with preterm labor requiring hospitalization (aOR: 2.69; 95% CI: 1.15-6.32). In our second analysis, there were 687 women with placenta previa, 633 (92%) with <2 prior CD, and 54 (8%) with ≥2 prior CD. The rate of PTD <34 weeks with ≥2 CD in the setting of placenta previa was not significantly increased (27.8 vs. 22.1%, aOR: 1.49; 95% CI: 0.77-2.90, p = 0.08); the maternal composite outcome (aOR: 4.85; 95% CI: 2.43-9.67) and transfusion of blood products (aOR: 6.41; 95% CI: 2.30-17.82) were noted to be higher in the group with ≥2 prior CD. CONCLUSION: Women with PAS who have had ≥2 prior CD as compared with women with <2 prior CD did not appear to have a higher risk of complications leading to delivery prior to 34 weeks. As such, considering the associated morbidity with early preterm birth, we would not recommend scheduled delivery prior to 34 weeks in this population. KEY POINTS: · We do not recommend delivery prior to 34 weeks of gestational age in PAS.. · PTD was not significantly increased in PAS with ≥2 CDs.. · PTD < 34 weeks of gestational age was not increased in placenta previa with ≥2 prior CDs..

Identifying Risk Factors for Cesarean Delivery in a Predominantly Hispanic Teenage Population: A 5-Year Retrospective Study.

STUDY OBJECTIVE: To identify risk factors for primary nonelective cesarean delivery, in a predominantly Hispanic teen population of an urban tertiary care center. DESIGN: Retrospective descriptive study. SETTING: A tertiary academic center with approximately 3000 deliveries per year. PARTICIPANTS: Our study population comprised all women (ages 13-19 years at time of delivery) who gave birth at our tertiary university hospital between July 2011 and July 2016. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Our main outcome of interest was primary nonelective cesarean delivery. RESULTS: Of the 958 included deliveries, 9.6% (92/958) were delivered via nonelective cesarean section. The population was 89% Hispanic with a mean age of 17.7 years. Age, body mass index at delivery, and neonatal birth weight were significantly associated with delivery via cesarean section. Mothers of neonates with extremes of birth weights (<2500 g, >4000 g) had higher odds of having a cesarean delivery, compared with neonates with normal birth weight (odds ratio, 3.27; 95% confidence interval, 1.90-5.63 and odds ratio, 4.43; 95% confidence interval, 1.33-14.72). CONCLUSION: Among adolescent patients, age, body mass index at delivery, and birth weight of the neonate were found to be risk factors that place the gravid teen at increased risk for cesarean delivery.
