ObjectiveTo characterize prescription and other medication use in a geographically and ethnically diverse cohort of women in their first pregnancy.MethodsIn a prospective, longitudinal cohort study of nulliparous women followed through pregnancy from the first trimester, medication use was chronicled longitudinally throughout pregnancy. Structured questions and aids were used to capture all medications taken as well as reasons they were taken. Total counts of all medications taken including number in each category and class were captured. Additionally, reasons the medications were taken were recorded. Trends in medications taken across pregnancy and in the first trimester were determined.ResultsOf the 9,546 study participants, 9,272 (97.1%) women took at least one medication during pregnancy with 9,139 (95.7%) taking a medication in the first trimester. Polypharmacy, defined as taking at least five medications, occurred in 2,915 (30.5%) women. Excluding vitamins, supplements, and vaccines, 73.4% of women took a medication during pregnancy with 55.1% taking one in the first trimester. The categories of drugs taken in pregnancy and in the first trimester include the following: gastrointestinal or antiemetic agents (34.3%, 19.5%), antibiotics (25.5%, 12.6%), and analgesics (23.7%, 15.6%, which includes 3.6%; 1.4% taking an opioid pain medication).ConclusionIn this geographically and ethnically diverse cohort of nulliparous pregnant women, medication use was nearly universal and polypharmacy was common.Clinical trial registrationClinicalTrials.gov, NCT01322529.

ObjectiveTo assess the relationships between self-reported psychosocial stress and preterm birth, hypertensive disease of pregnancy, and small-for-gestational-age (SGA) birth and to assess the extent to which these relationships account for racial and ethnic disparities in these adverse outcomes.MethodsSelf-reported measures of psychosocial stress (perceived stress, depression, racism, anxiety, resilience, and social support) were collected during pregnancy among a racially and ethnically diverse cohort of women enrolled in a prospective observational study of nulliparous women with singleton pregnancies, from eight clinical sites across the United States, between October 2010 and May 2014. The associations of preterm birth, hypertensive disease of pregnancy, and SGA birth with the self-reported measures of psychosocial stress as well as with race and ethnicity were evaluated.ResultsThe study included 9,470 women (60.4% non-Hispanic white, 13.8% non-Hispanic black, 16.7% Hispanic, 4.0% Asian, and 5.0% other). Non-Hispanic black women were significantly more likely to experience any preterm birth, hypertensive disease of pregnancy, and SGA birth than were non-Hispanic white women (12.2% vs 8.0%, 16.7% vs 13.4%, and 17.2% vs 8.6%, respectively; P

BackgroundThe significance of periconceptional nutrition for optimizing offspring and maternal health and reducing social inequalities warrants greater understanding of diet quality among US women.ObjectiveOur objective was to evaluate racial or ethnic and education inequalities in periconceptional diet quality and sources of energy and micronutrients.DesignCross-sectional analysis of data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be cohort.Participants and settingNulliparous women (N=7,511) were enrolled across eight US medical centers from 2010 to 2013.Main outcome measuresA semiquantitative food frequency questionnaire assessing usual dietary intake during the 3 months around conception was self-administered during the first trimester. Diet quality, measured using the Healthy Eating Index-2010 (HEI-2010), and sources of energy and micronutrients were the outcomes.Statistical analysesDifferences in diet quality were tested across maternal racial or ethnic and education groups using F tests associated with analysis of variance and χ2 tests.ResultsHEI-2010 score increased with higher education, but the increase among non-Hispanic black women was smaller than among non-Hispanic whites and Hispanics (interaction P value

Spontaneous preterm birth is a leading cause of infant mortality. Prediction, largely based on prior pregnancy outcomes, is not possible in women pregnant for the first time.To assess the accuracy of universal screening to predict spontaneous preterm birth in nulliparous women using serial measurements of vaginal fetal fibronectin levels and cervical length.A prospective observational cohort study of nulliparous women with singleton pregnancies, from 8 clinical sites across the United States between October 2010 and May 2014. Women and clinicians were blinded to results unless cervical shortening less than 15 mm was identified.Transvaginal cervical length and quantitative vaginal fetal fibronectin levels were reviewed at 2 study visits 4 or more weeks apart.Spontaneous preterm birth at less than 37 weeks was the primary outcome. Cervical length and quantitative fetal fibronectin were considered independently and together at each visit. Measurement distributions were compared for spontaneous preterm birth vs all other births. Spontaneous preterm birth before 32 weeks was a secondary outcome.The study included 9410 women (median age, 27.0 [interquartile range, 9.0] years; 60.7% non-Hispanic white, 13.8% non-Hispanic black, 16.5% Hispanic, 4.0% Asian, and 5.1% other), of whom 474 (5.0%) had spontaneous preterm births, 335 (3.6%) had medically indicated preterm births, and 8601 (91.4%) had term births. Among women with spontaneous preterm birth, cervical length of 25 mm or less occurred in 35 of 439 (8.0%) at 16 to 22 weeks' gestation and in 94 of 403 (23.3%) at 22 to 30 weeks' gestation. Fetal fibronectin levels of 50 ng/mL or greater at 16 to 22 weeks identified 30 of 410 women (7.3%) with spontaneous preterm birth and 31 of 384 (8.1%) at 22 to 30 weeks. The area under the receiver operating characteristic curve for screening between 22 and 30 weeks for fetal fibronectin level alone was 0.59 (95% CI, 0.56-0.62), for transvaginal cervical length alone was 0.67 (95% CI, 0.64-0.70), and for the combination as continuous variables was 0.67 (95% CI, 0.64-0.70).Among nulliparous women with singleton pregnancies, quantitative vaginal fetal fibronectin and serial transvaginal ultrasound cervical length had low predictive accuracy for spontaneous preterm birth. These findings do not support routine use of these tests in such women.

Background: To examine the incidence of overt hypothyroidism 1 and 5 years after pregnancies where screening before 21 weeks identified subclinical hypothyroidism (SH) or hypothyroxinemia (HT). Methods: Secondary analysis of two multicenter treatment trials for either SH or HT diagnosed between 8 and 20 weeks gestation. Current analyses focus only on individuals randomized to the placebo groups in the two parallel studies. SH was diagnosed with thyrotropin (TSH) ≥4.0 mU/L and normal free T4 (fT4) (0.86–1.9 ng/dL). HT was diagnosed with normal TSH (0.08–3.99 mU/L) but fT4 <0.86 ng/dL. Serum from initial testing was stored for later thyroid peroxidase (TPO) antibody assay; results were not returned for clinical management. At 1 and 5 years after delivery, participants were asked whether they had either been diagnosed with or were being treated for a thyroid condition. Maternal serum was collected at these visits and thyroid function measured. Subsequent overt hypothyroidism was defined as TSH ≥4.0 mU/L with fT4 <0.86 ng/dL. Results: Data for 1- and 5-year follow-up were available in 307 of the 338 participants with SH and 229 of the 261 with HT. Subsequent hypothyroidism was more common both at year 1 (13.4% vs. 3.1%, p < 0.001) and year 5 (15.6% vs. 2.6%, p < 0.001) for participants with SH compared with those with HT. This progression was more common in individuals with TSH values >10 mIU/mL. Baseline TPO level >50 IU/mL in participants with SH was associated with higher rates of hypothyroidism at year 1 (26.7% vs. 6.5%, odds ratio [OR] = 5.3 [confidence interval (CI) 2.6–10.7]) and year 5 (30.5% vs. 7.5%, OR = 5.4 [CI: 2.8–10.6]) compared with those with TPO levels ≤50 IU/mL. For participants with HT, no differences in overt hypothyroidism were seen at 1 year related to baseline TPO level >50 IU/mL (1/10 (10%) vs. 6/218 (2.8%), OR = 3.9 [CI: 0.43–36.1]), but more participants with TPO levels >50 IU/mL developed hypothyroidism by year 5 (2/10 (20%) vs. 4/218 (1.8%), OR = 13.4 [CI: 2.1–84.1]). Conclusion: SH is associated with higher rates of overt hypothyroidism or thyroid replacement therapy within 5 years of delivery than is HT when these conditions are diagnosed in the first half of pregnancy.

Background The aim of this study was to determine whether racial/ethnic differences in psychosocial measures, independent of economic status, exist among a large population of pregnant nulliparas. Methods Between October 2010 and September 2013, nulliparous women at eight U.S. medical centers were followed longitudinally during pregnancy and completed validated instruments to quantify several psychosocial domains: Cohen Perceived Stress Scale, trait subscale of the Spielberger Anxiety Inventory, Connor-Davidson Resilience Scale, Multidimensional Scale of Perceived Social Support, Krieger Racism Scale, Edinburgh Postnatal Depression Scale, and the Pregnancy Experience Scale. Scores were stratified and compared by self-reported race, ethnicity, and income. Results Complete data were available for 8,128 of the 10,038 women enrolled in the study. For all measures, race and ethnicity were significantly associated (p  0.05) except on the Krieger racism survey and the Edinburgh depression survey, which were exacerbated among NHB women with higher income (interaction, p

Objective To assess whether neonatal morbidities evident by the time of hospital discharge are associated with subsequent cerebral palsy (CP) or death. Study Design This is a secondary analysis of data from a multicenter placebo-controlled trial of magnesium sulfate for the prevention of CP. The association between prespecified intermediate neonatal outcomes (n = 11) and demographic and clinical factors (n = 10) evident by the time of discharge among surviving infants (n = 1889) and the primary outcome of death or moderate/severe CP at age 2 (n = 73) was estimated, and a prediction model was created. Results Gestational age in weeks at delivery (odds ratio [OR]: 0.74, 95% confidence interval [CI]: 0.67–0.83), grade III or IV intraventricular hemorrhage (IVH) (OR: 5.3, CI: 2.1–13.1), periventricular leukomalacia (PVL) (OR: 46.4, CI: 20.6–104.6), and male gender (OR: 2.5, CI: 1.4–4.5) were associated with death or moderate/severe CP by age 2. Outcomes not significantly associated with the primary outcome included respiratory distress syndrome, bronchopulmonary dysplasia, seizure, necrotizing enterocolitis, neonatal hypotension, 5-minute Apgar score, sepsis, and retinopathy of prematurity. Using all patients, the receiver operating characteristic curve for the final prediction model had an area under the curve of 0.84 (CI: 0.78–0.89). Using these data, the risk of death or developing CP by age 2 can be calculated for individual surviving infants. Conclusion IVH and PVL were the only neonatal complications evident at discharge that contributed to an individual infant's risk of the long-term outcomes of death or CP by age 2. A model that includes these morbidities, gestational age at delivery, and gender is predictive of subsequent neurologic sequelae. Key Points Factors known at hospital discharge are identified which are independently associated with death or CP by age 2. A model was created and validated using these findings to counsel parents. The risk of death or CP can be calculated at the time of hospital discharge. [ABSTRACT FROM AUTHOR]

Objective The fetal consequences of intrapartum fetal tachycardia with maternal fever or clinical chorioamnionitis are not well studied. We evaluated the association between perinatal morbidity and fetal tachycardia in the setting of intrapartum fever. Study Design Secondary analysis of a multicenter randomized control trial that enrolled 5,341 healthy laboring nulliparous women ≥36 weeks' gestation. Women with intrapartum fever ≥ 38.0°C (including those meeting criteria for clinical chorioamnionitis) after randomization were included in this analysis. Isolated fetal tachycardia was defined as fetal heart rate (FHR) ≥160 beats per minute for at least 10 minutes in the absence of other FHR abnormalities. FHR abnormalities other than tachycardia were excluded from the analysis. The primary outcome was a perinatal composite (5-minute Apgar's score ≤3, intubation, chest compressions, or mortality). Secondary outcomes included low arterial cord pH (pH < 7.20), base deficit ≥12, and cesarean delivery. Results A total of 986 (18.5%) of women in the trial developed intrapartum fever, and 728 (13.7%) met criteria to be analyzed; of these, 728 women 336 (46.2%) had maternal-fetal medicine (MFM) reviewer-defined fetal tachycardia, and 349 of the 550 (63.5%) women during the final hour of labor had validated software (PeriCALM) defined fetal tachycardia. After adjusting for confounders, isolated fetal tachycardia was not associated with a significant difference in the composite perinatal outcome (adjusted odds ratio [aOR] = 3.15 [0.82–12.03]) compared with absence of tachycardia. Fetal tachycardia was associated with higher odds of arterial cord pH <7.2, aOR = 1.48 (1.01–2.17) and of infants with a base deficit ≥ 12, aOR = 2.42 (1.02–5.77), but no significant difference in the odds of cesarean delivery, aOR = 1.33 (0.97–1.82). Conclusion Fetal tachycardia in the setting of intrapartum fever or chorioamnionitis is associated with significantly increased fetal acidemia defined as a pH <7.2 and base excess ≥12 but not with a composite perinatal morbidity. Key Points The perinatal outcomes associated with fetal tachycardia in the setting of maternal fever are undefined. Fetal tachycardia was not significantly associated with perinatal morbidity although the sample size was limited. Fetal tachycardia was associated with an arterial cord pH <7.2 and base deficit of 12 or greater. [ABSTRACT FROM AUTHOR]

Objective The aim of the study is to evaluate whether values and the shape of the glucose curve during the oral glucose tolerance test (OGTT) in pregnancy identify women at risk of developing hypertension (HTN) later in life. Study Design This category includes the secondary analysis of a follow-up from a mild gestational diabetes mellitus (GDM) study that included a treatment trial for mild GDM (n = 458) and an observational cohort of participants with abnormal 1-hour glucose loading test only (normal OGTT, n = 430). Participants were assessed at a median of 7 (IQR 6–8) years after their index pregnancy, and trained staff measured their blood pressure (systolic blood pressure [SBP]; diastolic blood pressure [DBP]). The association between values and the shape of the glucose curve during OGTT in the index pregnancy and the primary outcome defined as elevated BP (SBP ≥120, DBP ≥80 mm Hg, or receiving anti-HTN medications), and secondary outcome defined as stage 1 or higher (SBP ≥130, DBP ≥80 mm Hg, or receiving anti-HTN medications) at follow-up were evaluated using multivariable regression, adjusting for maternal age, body mass index, and pregnancy-associated hypertension during the index pregnancy. Results There was no association between fasting, 1-hour OGTT, and the outcomes. However, the 2-hour OGTT value was positively associated (adjusted odds ratio [aRR] per 10-unit increase 1.04, 95% CI 1.01–1.08), and the 3-hour was inversely associated (aRR per 10-unit increase 0.96, 95% CI 0.93–0.99) with the primary outcome. When the shape of the OGTT curve was evaluated, a monophasic OGTT response (peak at 1 hour followed by a decline in glucose) was associated with increased risk of elevated BP (41.3vs. 23.5%, aRR 1.66, 95% CI 1.17–2.35) and stage 1 HTN or higher (28.5 vs. 14.7%, aRR 1.83, 95% CI 1.15–2.92), compared with a biphasic OGTT response. Conclusion Among persons with mild GDM or lesser degrees of glucose intolerance, the shape of the OGTT curve during pregnancy may help identify women who are at risk of HTN later in life, with biphasic shape to be associated with lower risk. Key Points The shape of the Oral Glucose Tolerance Test curve may help identify patients who are at risk of having elevated BP or HTN 5 to 10 years following pregnancy. The 2-hour Oral Glucose Tolerance Test values is positively associated with elevated BP 5 to 10 years following pregnancy. This supports the concept of pregnancy as a window to future health and represents a potential novel biomarker for maternal cardiovascular health screening. [ABSTRACT FROM AUTHOR]

Cameron[sup.1] Author Affiliations: (1) Division of General [...], Women with gestational diabetes (GDM) have a fivefold higher risk of developing type 2 diabetes (T2DM). Furthermore, Hispanic and African-American women are disproportionately affected by GDM, but their views on prevention of T2DM after gestational diabetes are largely unknown. We conducted semi-structured interviews with 23 women (8 Hispanic, 8 African-American, 7 non-Hispanic White) from two academic clinics in Chicago, IL. Interview questions elicited perspectives on prevention of T2DM; the interview protocol was developed based on the Health Belief Model. Two investigators applied template analysis to identify emergent themes. Women conceptualized risk for T2DM based on family history, health behaviors, and personal history of GDM. A subgroup of women expressed uncertainty about how GDM influences risk for T2DM. Women who described a strong link between GDM and T2DM often viewed the diagnosis as a cue to action for behavior change. T2DM was widely viewed as a severe condition, and desire to avoid T2DM was an important motivator for behavior change. Children represented both a key motivator and critical barrier to behavior change. Women viewed preventive care as important to alert them to potential health concerns. Identified themes were congruent across racial/ethnic groups. Diagnosis with GDM presents a potent opportunity for engaging women in behavior change. To fully harness the potential influence of this diagnosis, healthcare providers should more clearly link the diagnosis of GDM with risk for future T2DM, leverage women&apos;s focus on their children to motivate behavior change, and provide support with behavior change during healthcare visits in the postpartum period and beyond.
