ABSTRACT

OBJECTIVE: The objective of this study was to examine the influence of gestational weight gain on the development of gestational hypertension/preeclampsia (GHTN/PE) in women with an obese prepregnancy body mass index (BMI). METHODS: Obese women with a singleton pregnancy enrolled at < 20 weeks were studied. Data were classified according to reported gestational weight gain (losing weight, under-gaining, within target, and over-gaining) from the recommended range of 11 to 9.7 kg and by obesity class (class 1 = BMI 30-34.9 kg/m(2), class 2 = 35-39.9 kg/m(2), class 3 = 40-49.9 kg/m(2), and class 4 ≥ 50 kg/m(2)). Rates of GHTN/PE were compared by weight gain group overall and within obesity class using Pearson chi-square statistics. RESULTS: For the 27,898 obese women studied, rates of GHTN/PE increased with increasing class of obesity (15.2% for class 1 and 32.0% for class 4). The incidence of GHTN/PE in obese women was not modified with weight loss or weight gain below recommended levels. Overall for obese women, over-gaining weight was associated with higher rates of GHTN/PE compared with those with a target rate for obesity classes 1 to 3 (each p < 0.001). CONCLUSION: Below recommended gestational weight gain did not reduce the risk for GHTN/PE in women with an obese prepregnancy BMI. These data support a gestational weight gain goal ≤ 9.7 kg in obese gravidas.

ABSTRACT

OBJECTIVE: Gestational diabetes (GDM) and obesity portend a high risk for subsequent type 2 diabetes. We examined maternal factors influencing the development of gestational diabetes (GDM) in obese women receiving 17-alpha-hydroxyprogesterone caproate (17OHPC) for preterm delivery prevention. MATERIALS AND METHODS: Retrospectively identified were 899 singleton pregnancies with maternal prepregnancy body mass indices of ≥30 kg/m(2) enrolled for either 17OHPC weekly administration (study group) or daily uterine monitoring and nursing assessment (control group). Patients with history of diabetes type 1, 2, or GDM were excluded. Maternal characteristics were compared between groups and for women with and without development of GDM. A logistic regression model was performed on incidence of GDM, controlling for significant univariate factors. RESULTS: The overall incidence of GDM in the 899 obese women studied was 11.9%. The incidence of GDM in the study group (n = 491) was 13.8% versus 9.6% in the control group (n = 408) (P = 0.048). Aside from earlier initiation of 17OHP and advanced maternal age, other factors including African American race, differing degrees of obesity, and use of tocolysis were not significant risks for the development of GDM. CONCLUSION: In obese women with age greater than 35 years, earlier initiation of 17OHPC may increase the risk for GDM.

ABSTRACT

BACKGROUND: The effect of eating speed on energy intake by weight status is unclear. OBJECTIVE: To examine whether the effect of eating speed on energy intake is the same in normal-weight and overweight/obese subjects. DESIGN: The effect of slow and fast eating speed on meal energy intake was assessed in a randomized crossover design. PARTICIPANTS/SETTING: Thirty-five normal-weight (aged 33.3±12.5 years; 14 women and 21 men) subjects and 35 overweight/obese (44.1±13.0 years; 22 women and 13 men) subjects were studied on 2 days during lunch in a metabolic kitchen. INTERVENTION: The subjects consumed the same meal, ad libitum, but at different speeds during the two eating conditions. The weight and energy content of the food consumed was assessed. Perceived hunger and fullness were assessed at specific times using visual analog scales. STATISTICAL ANALYSES: Effect of eating speed on ad libitum energy intake, eating rate (energy intake/meal duration), energy density (energy intake per gram of food and water consumed), and satiety were assessed by mixed-model repeated measures analysis. RESULTS: Meal energy intake was significantly lower in the normal-weight (804.5±438.9 vs 892.6±330.2 kcal; P=0.04) but not the overweight/obese (667.3±304.1 vs 724.8±355.5 kcal; P=0.18) subjects during the slow vs the fast eating condition. Both groups had lower meal energy density (P=0.005 and P=0.001, respectively) and eating rate (P<0.0001 in both groups) during the slow vs the fast eating condition. Both groups reported less hunger (P=0.01 and P=0.03, respectively), and the normal-weight subjects reported more fullness (P=0.02) at 60 minutes after the meal began during the slow compared with the fast eating condition. There was no eating speed by weight status interaction for any of the variables. CONCLUSIONS: Eating slowly significantly lowered meal energy intake in the normal-weight but not in the overweight/obese group. It lowered eating rate and energy density in both groups. Eating slowly led to lower hunger ratings in both groups and increased fullness ratings in the normal-weight group at 60 minutes from when the meal began.

ABSTRACT

OBJECTIVE: To examine the influence of nausea and vomiting of pregnancy (NVP) on pregnancy outcomes. METHODS: Outcomes were compared for primigravidas with a current singleton gestation enrolled at <20 weeks' gestation in a maternity risk screening and education program (n = 81 486). Patient-reported maternal characteristics and pregnancy outcomes were compared for women with and without NVP and within the NVP group for those with and without poor weight gain. RESULTS: 6.4% of women reported NVP as a pregnancy complication. Women reporting NVP were more likely to be younger, obese, single and smoke. They had higher rates of preterm delivery, pregnancy-induced hypertension and low birth weight <2500 g. Almost one-quarter of women with NVP had lower than recommended weight gain. Poor weight gain was associated with a higher incidence of adverse outcomes. Obesity, tobacco use and poor pregnancy weight gain independently increased the odds of an adverse outcome. CONCLUSION: NVP and subsequent poor weight gain may be associated with adverse pregnancy outcomes.

ABSTRACT

OBJECTIVE: The aim of the study was to examine pregnancy outcomes of healthy nulliparous women aged ≥ 40 years at delivery. STUDY DESIGN: The study included 53,480 nulliparous women aged 20 to 29 or ≥ 40 years delivering singleton infants, enrolled in a pregnancy risk assessment program between July 1, 2006, and August 1, 2011. Women reporting medical disorders, tobacco use, or conception with assistive reproductive technology were excluded. Data were grouped by body mass (obese or nonobese) and age (20-29 or ≥ 40 years). Pregnancy outcomes were compared within each body mass group for women aged 20 to 29 years versus ≥ 40 years and between obese and nonobese women aged ≥ 40 years. RESULTS: Within each body mass group, nulliparous women aged ≥ 40 years delivered at a significantly lower gestational age and had a greater incidence of cesarean delivery, gestational diabetes, preterm birth, and both low and very low birth weight infants, compared with controls aged 20 to 29 years. For women aged ≥ 40 years, obesity was associated with higher rates of adverse pregnancy outcomes. CONCLUSION: In healthy women, both advanced maternal age and obesity negatively influence pregnancy outcomes. Women who delay pregnancy until age 40+ years may modify their risk for cesarean section, preterm birth, and low-birth-weight infants by reducing their weight to nonobese levels before conception.

ABSTRACT

OBJECTIVE: To determine if the rates of recurrent spontaneous preterm birth in women receiving 17α-hydroxyprogesterone caproate (17P) differ according to maternal race. STUDY DESIGN: Retrospective analysis of a cohort of women enrolled in outpatient 17P administration at < 27 weeks. Maternal characteristics, obstetric history, and rates of recurrent preterm birth were determined using chi-square and multivariable Cox proportional hazards regression at two-tailed α = 0.05. Primary study outcome was defined as having a spontaneous preterm birth < 34 weeks. RESULTS: African-American women initiated 17P injections later (19.6 versus 18.9 weeks, p < 0.001) and discontinued injections earlier (33.2 versus 34.1 weeks, p < 0.001) than Caucasian women. Spontaneous recurrent preterm birth < 34 weeks was higher in African-Americans versus Caucasians receiving 17P (odds ratio 2.1; 95% confidence interval 1.7, 2.4). After adjusting for other significant factors, African-American race retained the strongest association with recurrent spontaneous preterm birth < 34 weeks. Within each racial group, short cervical length < 25 mm before 27 weeks' gestation had the highest hazard of recurrent spontaneous preterm delivery. CONCLUSION: Despite treatment with 17P, African-American women have higher rates of recurrent preterm birth.

ABSTRACT

OBJECTIVE: To examine the timing of elective delivery and neonatal intensive care unit (NICU) utilization of electively delivered infants from 2008 to 2011. METHODS: Analysis included 42,290 women with singleton gestation enrolled in a pregnancy education program, reporting uncomplicated pregnancies with elective labor induction (ELI) (n = 27,677) or scheduled cesarean delivery (SCD) (n = 14,613) at 37.0-41.9 weeks' gestation. Data were grouped by type and week of delivery (37.0-37.9, 38.0-38.9, and 39.0-41.9 weeks). ELI and SCD for each week of delivery from 2008 to 2011 and nursery utilization by delivery week were compared. RESULTS: During the 2008-2011 timeframe, a shift in timing of ELI and SCD toward ≥39.0 weeks was observed. In 2008, 80.9% of ELI occurred at ≥39.0 weeks versus 92.6% in 2011 (p < 0.001). In 2008, 60.5% of SCD occurred at ≥39.0 weeks versus 78.1% in 2011 (p < 0.001). NICU admission and prolonged nursery stays were highest at 37.0-37.9 weeks for both groups. CONCLUSIONS: We observed a shift toward later gestational age at elective delivery from 2008 to 2011 and increased NICU utilization for neonates born at <39 weeks' gestation.

ABSTRACT

OBJECTIVE: To determine if prophylactic cerclage improves pregnancy outcomes in women with twin pregnancies without a history of cervical insufficiency. STUDY DESIGN: Women with twin pregnancies who received outpatient preterm labor surveillance services between January 1990 and May 2004 for ≥1 day beginning at < 28.0 weeks' gestation were identified from a database. Patients with previous preterm delivery or a diagnosis of cervical incompetence in a previous or in the index pregnancy were excluded. Twin pregnancies managed with prophylactic cerclage were compared with twin pregnancies in which cerclage was not placed. The primary outcome was incidence of preterm birth prior to 32 weeks. Groups were compared using Fisher exact and Mann-Whitney U test statistics. RESULTS: Overall, 8,218 twin pregnancies met inclusion criteria, of which 146 women (1.8%) received prophylactic cerclage. Patients who received prophylactic cerclage had a significantly higher incidence of preterm birth before 32 weeks and infants with lower mean birth weight and longer nursery stays. No significant difference was seen in mean gestational age at delivery. This study had 80% power to detect a 7% reduction in the primary outcome. CONCLUSION: Prophylactic cerclage was not associated with a lower risk of preterm birth and adverse neonatal outcomes in twin pregnancies without history of cervical insufficiency.

ABSTRACT

OBJECTIVE: To examine the influence of maternal pre-pregnancy body mass index (BMI) on the rates of recurrent spontaneous preterm birth (SPTB) in women receiving 17α-hydroxyprogesterone caproate (17P). METHODS: Retrospective analysis of a cohort of 6253 women with a singleton gestation and prior SPTB enrolled in 17P home administration program between 16.0 and 26.9 weeks. Data were grouped by pre-pregnancy BMI (lean <18.5 kg/m(2), normal 18.5-24.9 kg/m(2), overweight 25-29.9 kg/m(2) and obese ≥30.0 kg/m(2)). Delivery outcomes were compared using χ(2) and Kruskal-Wallis tests with statistical significance set at p < 0.05. RESULTS: SPTB<28 weeks was significantly lower in normal weight women. Rates of recurrent SPTB<37 weeks were highest in the group with BMI<18.5 kg/m(2). Lean gravidas were younger, more likely to smoke, and less likely to be African-American than those with normal or increased BMI. In logistic regression, after controlling for race and prior preterm birth <28 weeks, the risk of SPTB<37 weeks decreased 2% for every additional 1 kg/m(2) increase in BMI. CONCLUSIONS: Recurrent spontaneous preterm delivery<37 weeks in patients on 17P is more common in lean women (BMI<18.5 kg/m(2)), and less common in obese women (BMI ≥30 kg/m(2)) suggesting that the current recommended dosing of 17 P is adequate for women with higher BMI.

ABSTRACT

OBJECTIVE: To examine the effect of obesity on maternal and neonatal outcomes in women diagnosed with gestational diabetes mellitus (GDM) and managed with diet only, glyburide, or insulin. STUDY DESIGN: Women with singleton gestations enrolled for outpatient services diagnosed with GDM and without history of pregnancy-related hypertension at enrollment or in a prior pregnancy were identified in a database. Women with GDM controlled by diet only (n = 3918), glyburide (n = 873), or insulin without prior exposure to oral hypoglycemic agents (n = 2229) were included. Pregnancy outcomes were compared for obese versus nonobese women within each treatment group and also compared across treatment groups within the obese and nonobese populations. RESULTS: Within each treatment group, obesity was associated with higher rates of cesarean delivery, pregnancy-related hypertension, macrosomia, and hyperbilirubinemia (all p < 0.05). Higher rates of pregnancy-related hypertension and hyperbilirubinemia were observed in women receiving glyburide. CONCLUSION: Obesity adversely affects pregnancy outcome in women with GDM. Higher rates of pregnancy-related hypertension and hyperbilirubinemia were observed in pregnant women receiving glyburide.

ABSTRACT

OBJECTIVE: Examine adherence to treatment guidelines and rates of recurrent spontaneous preterm birth (SPTB) in managed Medicaid patients prescribed 17 α-hydroxyprogesterone caproate (17P). STUDY DESIGN: A retrospective observational study of women receiving 17P between July 2004 and May 2010 through one of Centene's managed Medicaid programs. Included for analysis were singleton pregnancies without cerclage having SPTB history and prescribed 17P by their physician. Compounded 17P was administered through an outpatient program inclusive of patient education, weekly home nurse visits, and 24-7 telephonic nurse access. A health plan-directed pregnancy management program, Start Smart for Your Baby(®), supported the therapy with case management activities. RESULTS: Of the 790 patients studied, 58.6% initiated 17P in the recommended 16- to 20.9-week gestational age window. Elective discontinuation of 17P occurred in 18.6%. Of the 10,583 17P injections administered, 97.5% were administered within the recommended injection interval of 6 to 10 days. Recurrent SPTB occurred in 28.2% of women studied. CONCLUSION: Managed Medicaid patients enrolled in an outpatient 17P administration program supported with maternal case management have high rates of treatment compliance. Their pregnancy outcomes compare favorably to previously published reports that include both Medicaid and commercially insured patients.

ABSTRACT

OBJECTIVE: To determine if current recommendations for weight gain in twin pregnancies according to maternal prepregnancy body mass index (PPBMI) influence perinatal outcomes. METHODS: We identified women with twins enrolled in a maternity risk screening and education program with initial screening and prenatal care initiated at <20 weeks and delivery at >23.9 weeks. Women with normal, overweight, or obese PPBMI were included (n = 5129). Pregnancy outcomes were compared between those women with weight gain meeting or exceeding 2009 Institute of Medicine recommendations and patients who did not meet weight gain guidelines. RESULTS: Rates of spontaneous preterm delivery at <35 weeks were higher in all PPBMI groups for those with weight gain below guidelines. In all PPBMI groups, numbers of pregnancies with both infants weighing >2500 g or >1500 g were significantly higher for women gaining weight at or above guidelines. Logistic regression analysis was utilized to assess multivariate impact on outcome of spontaneous preterm delivery at <35 weeks showing that regardless of PPBMI level, women who gain below recommended guidelines are 50% more likely to deliver spontaneously at <35 weeks. CONCLUSION: In twin pregnancies, weight gain below recommended guidelines determined by maternal PPBMI is associated with higher rates of spontaneous preterm delivery at <35 weeks.

ABSTRACT

OBJECTIVE: The purpose of this study was to determine the role of previous term delivery on the rate of recurrent preterm birth in women with previous spontaneous preterm delivery (SPTD) who receive 17-alphahydroxyprogesterone caproate (17P) therapy. STUDY DESIGN: Women with singleton gestations who were receiving 17P therapy were studied. Rates of recurrent SPTD were compared for 1 or ≥2 SPTD with and without a previous term delivery. RESULTS: Five thousand one hundred two women had 1 previous SPTD, and 2217 women had ≥2 SPTDs. In women with 1 previous SPTD, a previous term delivery had lower rates of SPTD at <35 weeks (8.4% vs 11.2%; P = .002) and preterm delivery at <32 weeks (4.7% vs 6.2%; P = .027) compared with those women with no such history. No differences were found for SPTD at <35 weeks with ≥2 SPTDs. CONCLUSION: In patients who received 17P therapy with 1 previous SPTD, a previous term delivery confers a reduction in risk of preterm delivery at <37, <35, and <32 weeks' gestation; such reduction is not evident with ≥2 previous SPTDs.

ABSTRACT

OBJECTIVE: We sought to compare rates of recurrent spontaneous preterm birth (SPTB) in women receiving 17-α-hydroxyprogesterone caproate (17P) with prior SPTB due to preterm labor (PTL) vs preterm premature rupture of membranes (PPROM). STUDY DESIGN: Women with singleton gestation having 1 prior SPTB enrolled at 16-24.9 weeks' gestation for weekly outpatient 17P administration were identified from a database. Rates of recurrent SPTB were compared between those with prior SPTB due to PTL or PPROM overall and by gestational age at prior SPTB. RESULTS: Records from 2123 women were analyzed. The prior PTL group vs the prior PPROM group experienced higher rates of recurrent SPTB at <37 weeks (29.7% vs 22.9%, P = .004), <35 weeks (14.0% vs 9.1%, P = .004), and <32 weeks (5.9% vs 3.3%, P = .024), respectively. CONCLUSION: Reason and gestational age of prior SPTB influence the likelihood of recurrent SPTB in women receiving 17P prophylaxis.

ABSTRACT

OBJECTIVE: To compare pregnancy outcomes postbariatric surgery for women who remain obese at conception to those who were not obese. METHODS: From a database of women who received outpatient perinatal services, we identified women with a history of bariatric surgery who are currently pregnant with a singleton gestation. Available maternal characteristics and pregnancy outcomes were compared between women whose prepregnancy body mass index (PPBMI) remained in the obese range (≥30 kg/m(2)) and those with a PPBMI of <30 kg/m(2) using Fisher exact test, independent Student's t test, and Mann-Whitney U test statistics. RESULTS: Of the 102 women identified, 52 (51%) were obese and 50 (49%) were not obese at conception. No differences were observed in maternal age, marital status, years from surgery to delivery, development of gestational diabetes, gestational age at delivery, neonatal intensive care unit (NICU) admission, or nursery days. Maternal obesity (≥30 kg/m(2)) postbariatric surgery was associated with higher rates of cesarean delivery (63.5% vs. 36.0%, p=0.010) and development of pregnancy-related hypertension (36.5% vs. 8.0%, p=0.001) compared to nonobese women (<30 kg/m(2)). CONCLUSIONS: Postbariatric surgery, an optimal goal should be to achieve a nonobese weight status before conception to reduce maternal complications, such as pregnancy-related hypertension and cesarean delivery.

ABSTRACT

We examined treatment outcomes in women with severe nausea and vomiting of pregnancy (NVP) receiving outpatient nursing support and either subcutaneous metoclopramide or subcutaneous ondansetron via a microinfusion pump. Among women receiving outpatient nursing services, we identified those diagnosed with severe NVP having a Pregnancy-Unique Quantification of Emesis (PUQE) score of greater than 12 at enrollment and prescribed either metoclopramide (N = 355) or ondansetron (N = 521) by their physician. Maternal characteristics, response to treatment, and start versus stop values were compared between the medication groups. Allocation to group was based on intention-to-treat protocol. Maternal characteristics were similar between the groups. Days to reduction in PUQE score levels were similar (median 2 days, metoclopramide; 3 days, ondansetron; P = 0.206). Alteration from metoclopramide to ondansetron (31.8%) was more frequent than alteration from ondansetron to metoclopramide (4.4%; P < 0.001). Improvement of NVP symptoms and reduced need for hospitalization was noted with both medications. Treatment with either metoclopramide or ondansetron resulted in significant improvement of NVP symptoms with half of women showing a reduction from severe symptoms to moderate or mild symptoms within 3 days of treatment initiation. Alteration in treatment was significantly greater in patients initially prescribed metoclopramide.

ABSTRACT

In 2009, the Institute of Medicine (IOM) revised their pregnancy weight gain guidelines, recommending gestational weight gain of 11-20 pounds for women with prepregnancy BMI >30 kg/m(2). We investigated the potential influence of the new guidelines on perinatal outcomes using a retrospective analysis (n = 691), comparing obese women who gained weight during pregnancy according to the new guidelines to those who gained weight according to traditional recommendations (25-35 pounds). We found no statistical difference between the two weight gain groups in infant birth weight, cesarean delivery rate, pregnancy-related hypertension, low birth weight infants, macrosomia, neonatal intensive care unit admissions, or total nursery days. Despite showing no evidence of other benefits, our data suggest that obese women who gain weight according to new IOM guidelines are no more likely to have low birth weight infants. In the absence of national consensus on appropriate gestational weight gain guidelines, our data provide useful data for clinicians when providing evidence-based weight gain goals for their obese patients.

ABSTRACT

OBJECTIVE: To examine the impact of maternal obesity on maternal and neonatal outcomes in pregnancies complicated with gestational diabetes mellitus (GDM). METHODS: Women with singleton pregnancies and GDM enrolled in an outpatient GDM education, surveillance and management program were identified. Maternal and neonatal pregnancy outcomes were compared for obese (pre-pregnancy BMI ≥ 30 kg/m(2)) and non-obese (pre-pregnancy BMI < 30 kg/m(2)) women and for women across five increasing pre-pregnancy BMI categories. RESULTS: A total of 3798 patients were identified. Maternal obesity was significantly associated with the need for oral hypoglycemic agents or insulin, development of pregnancy-related hypertension, interventional delivery, and cesarean delivery. Adverse neonatal outcomes were also significantly increased including stillbirth, macrosomia, shoulder dystocia, need for NICU admission, hypoglycemia, and jaundice. When looking across five increasing BMI categories, increasing BMI was significantly associated with the same adverse maternal and neonatal outcomes. CONCLUSION: In women with GDM, increasing maternal BMI is significantly associated with worse maternal and neonatal outcomes.

ABSTRACT

We evaluated the impact of adherence to the new Institute of Medicine weight gain guidelines within each prepregnancy body mass index (PPBMI) category on the development of pregnancy-related hypertension (PRH). Patients with singleton term deliveries (≥37 weeks) with documented PPBMI and pregnancy weight gain information were identified from a database of women enrolled for outpatient nursing services. Included were women without history of cardiovascular disease, PRH, or diabetes at initiation of services (N = 7676). Data were stratified by PPBMI (underweight = < 18.5 kg/m(2); normal weight = 18.5 to 24.9 kg/m(2); overweight = 25.0 to 29.9 kg/m(2); obese = ≥ 30.0 kg/m(2)). PRH rates were compared overall and within each PPBMI group for those women gaining less than recommendations, within recommendations, and above recommendations using Pearson's chi-square and Kruskal-Wallis H test statistics. Overall, PRH rates were 5.0%, 5.4%, and 10.8% for less than, within, and above recommendation groups, respectively (P < 0.001). Above recommendation weight gain resulted in higher PRH incidence in each PPBMI category (underweight 7.6%, normal weight 6.2%, overweight 12.4%, and obese 17.0%), reaching statistical significance in all but the underweight PPBMI group. Excessive weight gain above established guidelines was associated with increased rates of PRH. Regardless of PPBMI, women should be counseled to avoid excessive weight gain during pregnancy.
