Item Antenatal Fetal Adrenal Measurements at 22 to 30 Weeks' Gestation, Fetal Growth Restriction, and Perinatal Morbidity(Thieme, 2021) Blue, Nathan R.; Hoffman, Matthew; Allshouse, Amanda A.; Grobman, William A.; Simhan, Hyagriv N.; Turan, Ozhan M.; Parry, Samuel; Chung, Judith H.; Reddy, Uma; Haas, David M.; Myers, Stephen; Mercer, Brian; Saade, George R.; Silver, Robert M.; Obstetrics and Gynecology, School of MedicineObjective: Our objective was to test the association of fetal adrenal size with perinatal morbidity among fetuses with fetal growth restriction (FGR; estimated fetal weight [EFW] < 10th percentile). Study design: This was a secondary analysis of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be (nuMoM2b) adrenal study, which measured fetal adrenal gland size at 22 to 30 weeks' gestation. We analyzed the transverse adrenal area (TAA) and fetal zone area (absolute measurements and corrected for fetal size) and the ratio of the fetal zone area to the total transverse area using a composite perinatal outcome of stillbirth, neonatal intensive care unit admission, respiratory distress syndrome, necrotizing enterocolitis, retinopathy of prematurity, sepsis, mechanical ventilation, seizure, or death. Among fetuses with FGR, adrenal measurements were compared between those that did and did not experience the composite perinatal outcome. Results: There were 1,709 eligible neonates. Seven percent (n = 120) were diagnosed with FGR at the time of adrenal measurement, and 14.7% (n = 251) experienced perinatal morbidity. EFW-corrected and absolute adrenal measurements were similar among fetuses with and without FGR as well as among those who did and did not experience morbidity. The area under the curve for corrected TAA was 0.52 (95% confidence interval 0.38-0.67). Conclusion: In our cohort, adrenal size was not associated with risk of morbidity among fetuses with FGR.Item Association of a Mediterranean Diet Pattern With Adverse Pregnancy Outcomes Among US Women(American Medical Association, 2022-12-01) Makarem, Nour; Chau, Kristi; Miller, Eliza C.; Gyamfi-Bannerman, Cynthia; Tous, Isabella; Booker, Whitney; Catov, Janet M.; Haas, David M.; Grobman, Wiliam A.; Levine, Lisa D.; McNeil, Rebecca; Merz, C. Noel Bairey; Reddy, Uma; Wapner, Ronald J.; Wong, Melissa S.; Bello, Natalie A.; Obstetrics and Gynecology, School of MedicineImportance: The Mediterranean diet pattern is inversely associated with the leading causes of morbidity and mortality, including metabolic diseases and cardiovascular disease, but there are limited data on its association with adverse pregnancy outcomes (APOs) among US women. Objective: To evaluate whether concordance to a Mediterranean diet pattern around the time of conception is associated with lower risk of developing any APO and individual APOs. Design, setting, and participants: This prospective, multicenter, cohort study, the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be, enrolled 10 038 women between October 1, 2010, and September 30, 2013, with a final analytic sample of 7798 racially, ethnically, and geographically diverse women with singleton pregnancies who had complete diet data. Data analyses were completed between June 3, 2021, and April 7, 2022. Exposures: An Alternate Mediterranean Diet (aMed) score (range, 0-9; low, 0-3; moderate, 4-5; and high, 6-9) was computed from data on habitual diet in the 3 months around conception, assessed using a semiquantitative food frequency questionnaire. Main outcomes and measures: Adverse pregnancy outcomes were prospectively ascertained and defined as developing 1 or more of the following: preeclampsia or eclampsia, gestational hypertension, gestational diabetes, preterm birth, delivery of a small-for-gestational-age infant, or stillbirth. Results: Of 7798 participants (mean [SD] age, 27.4 [5.5] years), 754 (9.7%) were aged 35 years or older, 816 (10.5%) were non-Hispanic Black, 1294 (16.6%) were Hispanic, and 1522 (19.5%) had obesity at baseline. The mean (SD) aMed score was 4.3 (2.1), and the prevalence of high, moderate, and low concordance to a Mediterranean diet pattern around the time of conception was 30.6% (n=2388), 31.2% (n=2430), and 38.2% (n=2980), respectively. In multivariable models, a high vs low aMed score was associated with 21% lower odds of any APO (adjusted odds ratio [aOR], 0.79 [95% CI, 0.68-0.92]), 28% lower odds of preeclampsia or eclampsia (aOR, 0.72 [95% CI, 0.55-0.93]), and 37% lower odds of gestational diabetes (aOR, 0.63 [95% CI, 0.44-0.90]). There were no differences by race, ethnicity, and prepregnancy body mass index, but associations were stronger among women aged 35 years or older (aOR, 0.54 [95% CI, 0.34-0.84]; P = .02 for interaction). When aMed score quintiles were evaluated, similar associations were observed, with higher scores being inversely associated with the incidence of any APO. Conclusions and relevance: This cohort study suggests that greater adherence to a Mediterranean diet pattern is associated with lower risk of APOs, with evidence of a dose-response association. Intervention studies are needed to assess whether dietary modification around the time of conception can reduce risk of APOs and their downstream associations with future development of cardiovascular disease risk factors and overt disease.Item Association of Health Literacy Among Nulliparous Individuals and Maternal and Neonatal Outcomes(American Medical Association, 2021-09-01) Yee, Lynn M.; Silver, Robert; Haas, David M.; Parry, Samuel; Mercer, Brian M.; Wing, Deborah A.; Reddy, Uma; Saade, George R.; Simhan, Hyagriv; Grobman, William A.; Obstetrics and Gynecology, School of MedicineImportance: Health literacy is considered an important social determinant of health that may underlie many health disparities, but it is unclear whether inadequate health literacy among pregnant individuals is associated with adverse maternal and neonatal outcomes. Objective: To assess the association between maternal health literacy and maternal and neonatal outcomes among nulliparous individuals. Design, setting, and participants: This was a secondary analysis of a large, multicenter cohort study of 10 038 nulliparous individuals in the US (2010-2013). Participants underwent 3 antenatal study visits and had detailed maternal and neonatal data abstracted. Data analysis was performed from July to December 2019. Exposures: Between 16 and 21 weeks of gestation, health literacy was assessed using the Rapid Estimate of Adult Literacy in Medicine-Short Form, a validated 7-item word recognition test. In accordance with standard scoring, results were dichotomized as inadequate vs adequate health literacy. Main outcomes and measures: On the basis of theoretical causal pathways between health literacy and health outcomes, a priori maternal and neonatal outcomes (determined via medical records) were selected for this analysis. Multivariable Poisson regression models were constructed to estimate the associations between health literacy and outcomes. Sensitivity analyses in which education was removed from models and that excluded individuals who spoke English as a second language were performed. Results: Of 9341 participants who completed the Rapid Estimate of Adult Literacy in Medicine-Short Form, the mean (SD) age was 27.0 (5.6) years, and 2540 (27.4%) had publicly funded prenatal care. Overall, 1638 participants (17.5%) had scores indicative of inadequate health literacy. Participants with inadequate health literacy were more likely to be younger (mean [SD] age, 22.9 [5.0] vs 27.9 [5.3] years), have less educational attainment (some college education or greater, 1149 participants [73.9%] vs 5279 participants [94.5%]), have publicly funded insurance (1008 participants [62.2%] vs 1532 participants [20.0%]), and report they were a member of an underrepresented racial or ethnic group (non-Hispanic Black, 506 participants [30.9%] vs 780 participants [10.1%]; Hispanic, 516 participants [31.5%] vs 948 participants [12.3%]) compared with those with adequate health literacy. Participants who had inadequate health literacy had greater risk of cesarean delivery (adjusted risk ratio [aRR], 1.11; 95% CI, 1.01-1.23) and major perineal laceration (aRR, 1.44; 95% CI, 1.03-2.01). The adjusted risks of small-for-gestational-age status (aRR, 1.34; 95% CI, 1.14-1.58), low birth weight (aRR, 1.33; 95% CI, 1.07-1.65), and 5-minute Apgar score less than 4 (aRR, 2.78; 95% CI, 1.16-6.65) were greater for neonates born to participants with inadequate health literacy. Sensitivity analyses confirmed these findings. Conclusions and relevance: These findings suggest that inadequate maternal health literacy is associated with a variety of adverse maternal and neonatal outcomes.Item Associations of the Neighborhood Built Environment with Gestational Weight Gain(Thieme, 2023) Grobman, William A.; Crenshaw, Emma G.; Marsh, Derek J.; McNeil, Rebecca B.; Pemberton, Victoria L.; Haas, David M.; Debbink, Michelle; Mercer, Brian M.; Parry, Samuel; Reddy, Uma; Saade, George; Simhan, Hyagriv; Mukhtar, Farhana; Wing, Deborah A.; Kershaw, Kiarri N.; NICHD nuMoM2b NHLBI nuMoM2b Heart Health Study Networks; Obstetrics and Gynecology, School of MedicineObjective: This study aimed to determine whether specific factors of the built environment related to physical activity and diet are associated with inadequate and excessive gestational weight gain (GWG). Study design: This analysis is based on data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be, a prospective cohort of nulliparous women who were followed from the beginning of their pregnancies through delivery. At each study visit, home addresses were recorded and geocoded. Locations were linked to several built-environment characteristics such as the census tract National Walkability Score (the 2010 Walkability Index) and the number of gyms, parks, and grocery stores within a 3-km radius of residential address. The primary outcome of GWG (calculated as the difference between prepregnancy weight and weight at delivery) was categorized as inadequate, appropriate, or excessive based on weight gained per week of gestation. Multinomial regression (generalized logit) models evaluated the relationship between each factor in the built environment and excessive or inadequate GWG. Results: Of the 8,182 women in the analytic sample, 5,819 (71.1%) had excessive GWG, 1,426 (17.4%) had appropriate GWG, and 937 (11.5%) had inadequate GWG. For the majority of variables examined, built environments more conducive to physical activity and healthful food availability were associated with a lower odds of excessive or inadequate GWG category. For example, a higher number of gyms or parks within 3 km of a participant's residential address was associated with lower odds of having excessive (gyms: adjusted odds ratio [aOR] = 0.93 [0.89-0.96], parks: 0.94 [0.90-0.98]) or inadequate GWG (gyms: 0.91 [0.86-0.96]; parks: 0.91 [0.86-0.97]). Similarly, a higher number of grocery stores was associated with lower odds of having excessive GWG (0.94 [0.91-0.97]). Conclusion: Among a diverse population of nulliparous women, multiple aspects of the built environment are associated with excessive and inadequate GWG.Item Associations of the Neighborhood Built Environment With Physical Activity Across Pregnancy(Human Kinetics, 2021-04-15) Kershaw, Kiarri N.; Marsh, Derek J.; Crenshaw, Emma G.; McNeil, Rebecca B.; Pemberton, Victoria L.; Cordon, Sabrina A.; Haas, David M.; Debbink, Michelle P.; Mercer, Brian M.; Parry, Samuel; Reddy, Uma; Saade, George; Simhan, Hyagriv; Wapner, Ronald J.; Wing, Deborah A.; Grobman, William A.; NICHD nuMoM2b Heart Health Study Network; NHLBI nuMoM2b Heart Health Study Network; Obstetrics and Gynecology, School of MedicineBackground: Several features of the neighborhood built environment have been shown to promote leisure-time physical activity (PA) in the general population, but few studies have examined its impact on PA during pregnancy. Methods: Data were extracted from 8362 Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be cohort participants (2010-2013). Residential address information was linked to 3 built environment characteristics: number of gyms and recreation areas within a 3-km radius of residence and census block level walkability. Self-reported leisure-time PA was measured in each trimester and dichotomized as meeting PA guidelines or not. Relative risks for cross-sectional associations between neighborhood characteristics and meeting PA guidelines were estimated using Poisson regression. Results: More gyms and recreation areas were each associated with a greater chance of meeting PA guidelines in models adjusted for sociodemographic characteristics and preexisting conditions. Associations were strongest in the third trimester where each doubling in counts of gyms and recreation areas was associated with 10% (95% confidence interval, 1.07-1.13) and 8% (95% confidence interval, 1.03-1.12), respectively, greater likelihood of meeting PA guidelines. Associations were similar though weaker for walkability. Conclusions: Results from a large, multisite cohort suggest that these built environment characteristics have similar PA-promoting benefits in pregnant women as seen in more general populations.Item Gestational Weight Gain and Pregnancy Outcomes among Nulliparous Women(Thieme, 2021) Dude, Annie M.; Grobman, William; Haas, David; Mercer, Brian M.; Parry, Samuel; Silver, Robert M.; Wapner, Ronald; Wing, Deborah; Saade, George; Reddy, Uma; Iams, Jay; Kominiarek, Michelle A.; Obstetrics and Gynecology, School of MedicineObjective: To determine the association between total gestational weight gain and perinatal outcomes. Study design: Data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be (NuMoM2b) study were used. Total gestational weight gain was categorized as inadequate, adequate, or excessive based on the 2009 Institute of Medicine guidelines. Outcomes examined included hypertensive disorders of pregnancy, mode of delivery, shoulder dystocia, large for gestational age or small for-gestational age birth weight, and neonatal intensive care unit admission. Results: Among 8,628 women, 1,666 (19.3%) had inadequate, 2,945 (34.1%) had adequate, and 4,017 (46.6%) had excessive gestational weight gain. Excessive gestational weight gain was associated with higher odds of hypertensive disorders (adjusted odds ratio [aOR] = 2.05, 95% confidence interval [CI]: 1.78-2.36) Cesarean delivery (aOR = 1.24, 95% CI: 1.09-1.41), and large for gestational age birth weight (aOR = 1.49, 95% CI: 1.23-1.80), but lower odds of small for gestational age birth weight (aOR = 0.59, 95% CI: 0.50-0.71). Conversely, inadequate gestational weight gain was associated with lower odds of hypertensive disorders (aOR = 0.75, 95% CI: 0.62-0.92), Cesarean delivery (aOR = 0.77, 95% CI: 0.65-0.92), and a large for gestational age birth weight (aOR = 0.72, 95% CI: 0.55-0.94), but higher odds of having a small for gestational age birth weight (aOR = 1.64, 95% CI: 1.37-1.96). Conclusion: Both excessive and inadequate gestational weight gain are associated with adverse maternal and neonatal outcomes.Item Objectively assessed sleep-disordered breathing during pregnancy and infant birthweight(Elsevier, 2021) Hawkins, Marquis; Parker, Corette B.; Redline, Susan; Larkin, Jacob C.; Zee, Phyllis P.; Grobman, William A.; Silver, Robert M.; Louis, Judette M.; Pien, Grace; Basner, Robert C.; Chung, Judith H.; Haas, David M.; Nhan-Chang, Chia-Ling; Simhan, Hyagriv N.; Blue, Nathan R.; Parry, Samuel; Reddy, Uma; Facco, Francesca; NICHD NuMoM2b; NHLBI NuMoM2b Heart Health Study Networks; Obstetrics and Gynecology, School of MedicineBackground: Sleep-disordered breathing (SDB) in pregnancy is associated with adverse maternal outcomes. The relationship between SDB and infant birthweight is unclear. This study's primary aim is to determine if objectively measured SDB in pregnancy is associated with infant birthweight. Methods: We measured SDB objectively in early (6-15 weeks' gestation) and mid (22-31 weeks' gestation) pregnancy in a large cohort of nulliparous women. SDB was defined as an Apnea-Hypopnea Index ≥5 and in secondary analyses we also examined measures of nocturnal hypoxemia. We used a modified Poisson regression approach to estimate relative risks (RR) of large-for-gestational-age (LGA: >90th percentile for gestational age) and small-for-gestational-age (SGA: <10th percentile for gestational age) birthweights. Results: The prevalence of early-pregnancy SDB was nearly 4%. The incidence of mid-pregnancy SDB was nearly 6.0%. The prevalence of LGA and SGA was 7.4% and 11.9%, respectively. Early-pregnancy SDB was associated with a higher risk of LGA in unadjusted models (RR 2.2, 95% CI 1.3-3.5) but not BMI-adjusted models (aRR 1.0, 95% CI 0.6-1.8). Mid-pregnancy SDB was not associated with SGA or LGA. Mid-pregnancy nocturnal hypoxemia (% of sleep time <90% oxygen saturation) and increasing nocturnal hypoxemia from early to mid-pregnancy were associated with a higher risk of LGA in BMI-adjusted models. SDB and nocturnal hypoxemia were not associated with SGA. Conclusions: SDB in pregnancy was not associated with an increased risk of LGA or SGA birthweight, independent of BMI. Some measures nocturnal hypoxemia were associated with an increase in LGA risk, independent of BMI.Item Prospective Evaluation of Placental Abruption in Nulliparous Women(Taylor & Francis, 2022) Lueth, Amir; Blue, Nathan; Silver, Robert M.; Allshouse, Amanda; Hoffman, Matthew; Grobman, William A.; Simhan, Hyagriv N.; Reddy, Uma; Haas, David M.; Obstetrics and Gynecology, School of MedicineIntroduction: Because most data on placental abruption are derived from retrospective studies, multiple sources of bias may have affected the results. Thus, we aimed to characterize risk factors and outcomes for placental abruption in a large prospective cohort of nulliparous women. Methods: This was a secondary analysis of women enrolled in the Nulliparous Pregnancy Outcomes Study Monitoring-to-be (nuMom2b) study, a prospective observational cohort. Participants were recruited in their first trimester of pregnancy from 8 sites and had 4 study visits, including at delivery. Placental abruption was defined by confirmed clinical criteria. The primary analysis was restricted to abruption identified antepartum and intrapartum. As a secondary analysis, we examined antepartum and intrapartum abruptions separately. We compared risk factors (maternal demographic and clinical characteristics) and outcomes in women with and without placental abruption using univariable and multivariable analyses as appropriate. Results: 9450 women were included in the primary analysis. Abruption was identified in 0.66% (n = 62), of which 35 (56%) were antepartum and 27 (44%) intrapartum. For women with abruption, the mean gestational age at delivery was 35.6 ± 4.4 weeks and 38.8 ± 2.2 weeks for women without abruption. Gravidity was associated with abruption (OR 3.1, 95% CI: 1.6-6.0). In univariate analysis, abruption was associated with cesarean delivery (OR 3.7, 95% CI: 2.2-6.0), blood transfusion (OR 3.8, 95% CI: 1.4-10.7), PPROM (OR 9.0, 95% CI: 5.4-15.1), preterm birth (OR 8.5, 95% CI: 5.1-14.2), SGA (OR 4.0, 95% CI: 2.3-6.95), RDS (OR 5.5, 95% CI: 2.6-11.2), IVH 20.2 (OR 20.2, 95% CI: 5.9-68.8) and ROP (OR 12.2, 95% CI: 2.8-52.6). However, after adjustment for confounders including gestational age, abruption was only associated with increased odds of cesarean delivery and blood transfusion. Results were similar when restricted to antepartum and intrapartum abruptions. Conclusion: Abruption was identified in <1% of nulliparous women. However, few maternal risk factors were identified. Neonatal morbidities were associated with an abruption and were primarily driven by gestational age due to preterm birth.Item Sleep-disordered Breathing in Pregnancy and after Delivery: Associations with Cardiometabolic Health(American Thoracic Society, 2022) Facco, Francesca L.; Redline, Susan; Hunter, Shannon M.; Zee, Phyllis C.; Grobman, William A.; Silver, Robert M.; Louis, Judette M.; Pien, Grace W.; Mercer, Brian; Chung, Judith H.; Merz, C. Noel Bairey; Haas, David M.; Nhan-Chang, Chia-Ling; Simhan, Hyagriv N.; Schubert, Frank P.; Parry, Samuel; Reddy, Uma; Saade, George R.; Hoffman, Matthew K.; Levine, Lisa D.; Wapner, Ronald J.; Catov, Janet M.; Parker, Corette B.; Obstetrics and Gynecology, School of MedicineRationale: Knowledge gaps exist regarding health implications of sleep-disordered breathing (SDB) identified in pregnancy and/or after delivery. Objectives: To determine whether SDB in pregnancy and/or after delivery is associated with hypertension (HTN) and metabolic syndrome (MS). Methods: nuMoM2b-HHS (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be Heart Health Study) (N = 4,508) followed participants initially recruited during their first pregnancy. Participants returned for a visit 2-7 years after pregnancy. This study examined a subgroup who underwent SDB assessments during their first pregnancy (n = 1,964) and a repeat SDB assessment after delivery (n = 1,222). Two SDB definitions were considered: 1) apnea-hypopnea index (AHI) ⩾ 5 and 2) oxygen desaturation index (ODI) ⩾ 5. Associations between SDB and incident HTN and MS were evaluated with adjusted risk ratios (aRRs). Measurements and Main Results: The aRR for MS given an AHI ⩾ 5 during pregnancy was 1.44 (95% confidence interval [CI], 1.08-1.93), but no association with HTN was found. ODI ⩾ 5 in pregnancy was associated with both an increased risk for HTN (aRR, 2.02; 95% CI, 1.30-3.14) and MS (aRR, 1.53; 95% CI, 1.19-1.97). Participants with an AHI ⩾ 5 in pregnancy that persisted after delivery were at higher risk for both HTN (aRR, 3.77; 95% CI, 1.84-7.73) and MS (aRR, 2.46; 95% CI, 1.59-3.76). Similar associations were observed for persistent ODI ⩾ 5 after delivery. Conclusions: An AHI ⩾ 5 in pregnancy was associated with an increased risk of MS. An ODI ⩾ 5 in pregnancy was significantly associated with both HTN and MS. Participants with persistent elevations in AHI and ODI during pregnancy and at 2-7 years after delivery were at the highest risk for HTN and MS.Item The association between personal weight gain goals, provider recommendations, and appropriate gestational weight gain(Elsevier, 2020) Dude, Annie M.; Plunkett, Beth; Grobman, William; Scifres, Christina M.; Mercer, Brian M.; Parry, Samuel; Silver, Robert M.; Wapner, Ronald; Wing, Deborah A.; Saade, George; Reddy, Uma; Iams, Jay; Simhan, Hyagriv; Kominiarek, Michelle A.; Obstetrics and Gynecology, School of MedicineBackground: Nearly half of all women exceed the 2009 Institute of Medicine guidelines for gestational weight gain. Excess gestational weight gain is associated with adverse pregnancy outcomes. Objective: Our objective was to determine whether having a personal gestational weight gain goal consistent with the Institute of Medicine's recommendations for appropriate gestational weight gain and whether having a discussion with one's obstetrical provider regarding that goal were associated with appropriate gestational weight gain. Study design: This is a secondary analysis of the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be study, a prospective cohort study of nulliparous women. We asked women at their first study visit (between 6 and 13 weeks' gestation) whether they had a gestational weight gain goal and what that goal was. Furthermore, we asked whether their provider discussed a gestational weight gain goal and what that goal was. We classified personal and provider-recommended gestational weight gain goals as consistent or inconsistent with the Institute of Medicine guidelines, taking into account a woman's initial body mass index category (underweight, normal weight, overweight, and obese). We included women with live singleton term deliveries (between 37 and 43 weeks' gestation) in this analysis. We classified the primary outcome, which was gestational weight gain (defined as the difference between first visit weight and final weight before delivery), as inadequate, appropriate, or excessive, based on the Institute of Medicine guidelines and initial body mass index category. We used Student t, Wilcoxon rank-sum, and chi-square tests for bivariable analyses, and multinomial logistic regression was performed to control for confounding variables. Results: Of 6727 eligible women, 3799 (56.5% of all eligible women) stated they had a gestational weight gain goal. Of the 3799 women with a stated goal, 2589 (38.5% of all women) had a goal consistent with the Institute of Medicine's recommendations. In addition, of the 6727 eligible women, 2188 (32.5%) reported that they discussed gestational weight gain with their provider, and 1548 of these (23.0% of all women) recalled that their provider gave a gestational weight gain goal in accordance with the Institute of Medicine guidelines. Although having any gestational weight gain goal was not associated with appropriate gestational weight gain, having a gestational weight gain goal that was consistent with the Institute of Medicine's recommendations was associated with a reduced risk of excessive (adjusted relative risk ratio, 0.77; 95% confidence interval, 0.64-0.92) and inadequate weight gain (adjusted relative risk ratio, 0.66; 95% confidence interval, 0.53-0.82). Conversely, discussing gestational weight gain goals with a provider was not associated with either inadequate or excessive gestational weight gain even if the provider's recommendations for gestational weight gain were consistent with the guidelines. Conclusion: Nulliparas who delivered singleton pregnancies at term who had a personal gestational weight gain goal consistent with the Institute of Medicine's recommendations were less likely to have excessive or inadequate gestational weight gain. Further study is required to evaluate the most effective way to communicate this information to patients.
