  • Maternal obesity and Gestational Weight Gain are risk factors for infant death.
    Obesity (Silver Spring Md.), 2015
    Co-Authors: Lisa M. Bodnar, Katherine P. Himes, Lara L. Siminerio, Jennifer A. Hutcheon, Timothy L. Lash, Sara M. Parisi, Barbara Abrams
    Abstract:

    Objective Assessment of the joint and independent relationships of Gestational Weight Gain and prepregnancy body mass index (BMI) on risk of infant mortality was performed. Methods This study used Pennsylvania linked birth-infant death records (2003-2011) from infants without anomalies born to mothers with prepregnancy BMI categorized as underWeight (n = 58,973), normal Weight (n = 610,118), overWeight (n = 296,630), grade 1 obesity (n = 147,608), grade 2 obesity (n = 71,740), and grade 3 obesity (n = 47,277). Multivariable logistic regression models stratified by BMI category were used to estimate dose-response associations between z scores of Gestational Weight Gain and infant death after confounder adjustment. Results Infant mortality risk was lowest among normal-Weight women and increased with rising BMI category. For all BMI groups except for grade 3 obesity, there were U-shaped associations between Gestational Weight Gain and risk of infant death. Weight loss and very low Weight Gain among women with grades 1 and 2 obesity were associated with high risks of infant mortality. However, even when Gestational Weight Gain in women with obesity was optimized, the predicted risk of infant death remained higher than that of normal-Weight women. Conclusions Interventions aimed at substantially reducing preconception Weight among women with obesity and avoiding very low or very high Gestational Weight Gain may reduce risk of infant death.

  • practitioner advice and Gestational Weight Gain
    Journal of Womens Health, 2011
    Co-Authors: Suzanne Phelan, Maureen G. Phipps, Barbara Abrams, Francine Darroch, Andrew Schaffner, Rena R. Wing
    Abstract:

    Abstract Background: The purpose of this study was to investigate receipt of Gestational Weight Gain advice in prenatal care and ideal and expected Gestational Weight Gain outcomes for normal Weight and overWeight/obese women. Methods: This was a cross-sectional study of normal Weight (n = 203) and overWeight/obese (n = 198) women in early (<16 weeks) pregnancy. Results: Less than half of participants (41.7%) reported receiving Weight Gain advice from a practitioner. In multivariate models, pregravid Weight status was not significantly related to receiving advice. However, women with lower income (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.13-0.77, p = 0.01), younger age (OR 0.93, 95% CI 0.87-0.99, p = 0.02), and multiparity (OR 0.49, 95% CI 0.28-0.87, p = 0.02) were least likely to report receiving advice. Among those receiving advice, most (85%) received accurate advice; however, overWeight/obese women were more likely to be advised to overGain compared with normal Weight women (22.2% vs. 2.3%...

  • Severe obesity, Gestational Weight Gain, and adverse birth outcomes
    The American journal of clinical nutrition, 2010
    Co-Authors: Lisa M. Bodnar, Anna Maria Siega-riz, Hyagriv N. Simhan, Katherine P. Himes, Barbara Abrams
    Abstract:

    Background: The 2009 Institute of Medicine (IOM) Committee to Reevaluate Gestational Weight Gain Guidelines concluded that there were too few data to inform Weight-Gain guidelines by obesity severity. Therefore, the committee recommended a single range, 5–9 kg at term, for all obese women. Objective: We explored associations between Gestational Weight Gain and small-for-Gestational-age (SGA) births, large-for-Gestationalage (LGA) births, spontaneous preterm births (sPTBs), and medically indicated preterm births (iPTBs) among obese women who were stratified by severity of obesity. Design: We studied a cohort of singleton, live-born infants without congenital anomalies born to obesity class 1 (prepregnancy body mass index [BMI (in kg/m 2 )]: 30–34.9; n = 3254), class 2 (BMI: 35–39.9; n = 1451), and class 3 (BMI: 40; n = 845) mothers. We defined the adequacy of Gestational Weight Gain as the ratio of observed Weight Gain to IOM-recommended Gestational Weight Gain. Results: The prevalence of excessive Gestational Weight Gain declined, and Weight loss increased, as obesity became more severe. Generally, Weight loss was associated with an elevated risk of SGA, iPTB, and sPTB, and a high Weight Gain tended to increase the risk of LGA and iPTB. Weight Gains associated with probabilities of SGA and LGA of 10% and a minimal risk of iPTB and sPTB were as follows: 9.1–13.5 kg (obesity class 1), 5.0–9 kg (obesity class 2), 2.2 to ,5.0 kg (obesity class 3 white women), and ,2.2 kg (obesity class 3 black women). Conclusion: These data suggest that the range of Gestational Weight Gain to balance risks of SGA, LGA, sPTB, and iPTB may vary by severity of obesity. Am J Clin Nutr 2010;91:1642–8.

  • epidemiology of Gestational Weight Gain and body Weight changes after pregnancy
    Epidemiologic Reviews, 1999
    Co-Authors: Erica P. Gunderson, Barbara Abrams
    Abstract:

    Women are universally concerned about whether pregnancy will have a lasting impact on their body Weight. Anecdotal reports and studies of severely obese women have pointed to pregnancy as a cause of their obesity. In a Stockholm obesity clinic, 40-50 percent of women (mean age 47.8 ± 10.7 years) attributed the onset of their obesity to childbearing, and 73 percent reported a retention of 10 kg after pregnancy (1, 2). However, most of the evidence from observational studies about the influence of pregnancy on postpartum body Weight does not support these perceptions. For the majority of women, body Weight at 6-18 months postpartum is no more than 1-2 kg greater than preconceptional Weight (3-9). Yet, at least 14-20 percent of women in national surveys were more than 5 kg heavier by 6-18 months postpartum (3, 4, 6-8). This evidence suggests that pregnancy may substantially increase postpartum body Weight for subgroups of women, such as those with high Gestational Weight Gain (6). A more recent study found an increased risk of becoming overWeight among women who had a single pregnancy compared with nongravid women (10). Thus, estimates of average body Weight change do not reflect the excess Weight increases experienced by a sizable number of women; this may be further compounded over subsequent pregnancies and contribute to the development of obesity. Factors suspected of influencing postpartum body Weight include Gestational Weight Gain, pregravid Weight, race/ethnicity, parity, and lactation. Body Weight at conception may be particularly important among race/ethnic groups in which the prevalence of obesity is high (8). Both mean Gestational Weight Gain and prevalence of overWeight women in the US population have increased over the past two decades (8, 11-13). It has not been established whether increased Gestational Weight Gain is responsible for part of the increasing

  • Trimester-Specific Gestational Weight Gain and Infant Size for Gestational Age.
    PloS one, 2016
    Co-Authors: Sneha B. Sridhar, Monique M. Hedderson
    Abstract:

    Gestational Weight Gain is known to influence fetal growth. However, it is unclear whether the associations between Gestational Weight Gain and fetal growth vary by trimester. In a diverse cohort of 8,977 women who delivered a singleton between 2011 and 2013, we evaluated the associations between trimester-specific Gestational Weight Gain and infant size for Gestational age. Gestational Weight Gain was categorized per the 2009 Institute of Medicine (IOM) recommendations; meeting the recommendations was the referent. Large for Gestational age and small for Gestational age were defined as birthWeight > 90th percentile or

  • Gestational Weight Gain and risk of Gestational diabetes mellitus.
    Obstetrics and gynecology, 2010
    Co-Authors: Monique M. Hedderson, Erica P. Gunderson, Assiamira Ferrara
    Abstract:

    Gestational diabetes mellitus (GDM), defined as glucose intolerance with onset or first recognition during the second or third trimester of pregnancy,1 complicates 4–7% of pregnancies in the United States.1 Gestational diabetes mellitus is associated with an increased risk of perinatal complications,2 and in the long term, women with a history of GDM3 and their offspring4 are at high risk of developing type 2 diabetes mellitus. Weight Gain during pregnancy consists of 30% maternal fat accretion,5 with the second half of a normal pregnancy characterized by progressive insulin resistance.6 The composition of Weight Gain also varies by trimester7,8: maternal Weight Gain early in pregnancy is disproportionately fat and could influence subsequent maternal insulin resistance.7 Surprisingly, few studies have examined the association between Gestational Weight Gain and the risk of GDM. The association must be examined before the diagnosis of GDM to prevent confounding by treatment for GDM. To date, only three studies, with small numbers of women, have examined Gestational Weight Gain from before pregnancy to the glucose screening test for GDM and the risk of abnormal glucose metabolism, with conflicting results.9–11 In 2009, the Institute of Medicine (IOM) released new recommendations for Gestational Weight Gain, including specific recommendations for rate of Weight Gain by prepregnancy body mass index (BMI) (Weight in kilograms divided by height in meters squared).12 The IOM report noted there was a lack of evidence regarding the role of Gestational Weight Gain in relation to GDM.12 It is not known whether Weight Gains that adhere to these new recommendations can reduce the risk of GDM. To address this question, we conducted a nested case-control study to examine the occurrence of GDM in relation to the rate of Gestational Weight Gain (in kilograms per week) assessed before the 50-g, 1-hour glucose challenge screening test (referred to as the glucose screening test hereafter) for GDM. We specifically examined the following measures: 1) the overall rate of Gestational Weight Gain, 2) trimester-specific rates of Weight Gain, and 3) trimester-specific rates of Weight Gain exceeding compared with adhering to the 2009 IOM recommendations.

  • pre pregnancy body mass index Gestational Weight Gain and other maternal characteristics in relation to infant birth Weight
    Maternal and Child Health Journal, 2008
    Co-Authors: Ihunnaya O Frederick, Michelle A Williams, Anne E Sales, Diane P Martin, Marcia Killien
    Abstract:

    Objectives Infant birth Weight is influenced by modifiable maternal pre-pregnancy behaviors and characteristics. We evaluated the relationship among pre-pregnancy body mass index (BMI), Gestational Weight Gain, and infant birth Weight, in a prospective cohort study. Methods Women were enrolled at ≤20 weeks gestation, completed in-person interviews and had their medical records reviewed after delivery. Infant birth Weight was first analyzed as a continuous variable, and then grouped into Low birth Weight (LBW) (<2,500 g), normal birth Weight (2,500–3,999 g), and macrosomia (≥4,000 g) in categorical analysis. Pre-pregnancy BMI and Gestational Weight Gain were categorized based on Institute of Medicine BMI groups and Gestational Weight Gain guidelines. Associations among infant birth Weight and pre-pregnancy BMI, Gestational Weight Gain, and other factors were evaluated using multivariate regression. Risk ratios were estimated using generalized linear modeling procedures. Results Pre-pregnancy BMI was independently and positively associated with infant birth Weight (β = 44.7, P = 0.001) after adjusting for confounders, in a quadratic model. Gestational Weight Gain was positively associated with infant birth Weight (β = 19.5, P < 0.001). Lower infant birth Weight was associated with preterm birth (β = −965.4, P < 0.001), nulliparity (β = −48.6, P = 0.015), and female babies (β = −168.7, P < 0.001). Less than median Gestational Weight Gain was associated with twice the risk of LBW (RR = 2.04, 95% CI 1.34–3.11). Risk of macrosomia increased with increasing pre-pregnancy BMI and Gestational Weight Gain (P for linear trend <0.001). Conclusions These findings support the need to balance pre-pregnancy Weight and Gestational Weight Gain aGainst the risk of LBW and macrosomia among lean and obese women, respectively.

  • Food insecurity during pregnancy and Gestational Weight Gain.
    American journal of obstetrics & gynecology MFM, 2019
    Co-Authors: Lindsay A. Cheu, Lynn M. Yee, Michelle A. Kominiarek
    Abstract:

    Abstract Background Limited or uncertain availability of nutritionally adequate and safe food, known as food insecurity, has been associated with obesity and other adverse health outcomes, but has been rarely studied in pregnancy. Food insecurity may negatively affect behavioral and physiological changes during pregnancy and may be associated with poor perinatal outcomes including Gestational Weight Gain. Objective Given the lack of information on the role of food insecurity in pregnancy and the possible relationship with perinatal outcomes such as Gestational Weight Gain, the objective of this study was to examine the association between food insecurity and Gestational Weight Gain in a diverse cohort of pregnant women. Study Design This was an observational study of 299 English-speaking women who delivered live-born singleton gestations at ≥24 weeks at a single tertiary care center. During their postpartum hospitalizations, enrolled women completed a survey of food security status during pregnancy using the United States Department of Agriculture Household Food Security Survey Module. Scores were analyzed as inadequate (marginal, low, or very low) vs. adequate (high) food security. Women without pre-pregnancy body mass index and Gestational Weight Gain data were excluded. The primary outcome was Gestational Weight Gain categorized as inadequate, adequate, or excessive based on 2009 National Academy of Medicine guidelines, which account for body mass index. Secondary outcomes included total Gestational Weight Gain and other maternal and neonatal outcomes. Multivariable linear and multinomial logistic regressions were performed to assess the independent associations of food insecurity with Gestational Weight Gain after controlling for potential confounding factors. Results Of the 299 women enrolled in the study, 11.0% (n=33) reported inadequate food security during pregnancy. Women with inadequate food security were younger (p=0.007), had a greater mean body mass index (p Conclusions In this diverse, urban population, more than 1 in 10 women experienced food insecurity during pregnancy. Inadequate food security was associated with lower median total Gestational Weight Gain, but not with excessive Gestational Weight Gain as determined by 2009 National Academy of Medicine categories.

  • Gestational Weight Gain and group prenatal care: a systematic review and meta-analysis
    BMC pregnancy and childbirth, 2019
    Co-Authors: Michelle A. Kominiarek, Adam K. Lewkowitz, Ebony B. Carter, Susan Fowler, Melissa A. Simon
    Abstract:

    Group visits for chronic medical conditions in non-pregnant populations have demonstrated successful outcomes including greater Weight loss compared to individual visits for Weight management. It is plausible that group prenatal care can similarly assist women in meeting Gestational Weight Gain goals. The purpose of this study was to evaluate the effect of group vs. traditional prenatal care on Gestational Weight Gain. A keyword search of Medline, Embase, Scopus, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, clinicaltrials.gov, and Google Scholar was performed up to April 2017. Studies were included if they compared Gestational Weight Gain in a group prenatal care setting to traditional prenatal care in either randomized controlled trials, cohort, or case-control studies. The primary and secondary outcomes were excessive and adequate Gestational Weight Gain according to the Institute of Medicine guidelines. Heterogeneity was assessed with the Q test and I2 statistic. Pooled relative risks (RRs) and confidence intervals (CI) were reported with random-effects models from the randomized controlled trials (RCT) and cohort studies. One RCT, one secondary analysis of an RCT, one study with “random assignment”, and twelve cohort studies met the inclusion criteria for a total of 13,779 subjects. Thirteen studies used the CenteringPregnancy model, defined by 10 sessions that emphasize goal setting and self-monitoring. Studies targeted specific populations such as adolescents, African-Americans, Hispanics, active-duty military or their spouses, and women with obesity or Gestational diabetes. There were no significant differences in excessive [7 studies: pooled rates 47% (1806/3582) vs. 43% (3839/8521), RR 1.09, 95% CI 0.97–1.23] or adequate Gestational Weight Gain [6 studies: pooled rates 31% (798/2875) vs. 30% (1410/5187), RR 0.92, 95% CI 0.79–1.08] in group and traditional prenatal care among the nine studies that reported categorical Gestational Weight Gain outcomes in the meta-analysis. Group prenatal care was not associated with excessive or adequate Gestational Weight Gain in the meta-analysis. Since outcomes were overall inconsistent, we propose that prenatal care models (e.g., group vs. traditional) should be evaluated in a more rigorous fashion with respect to Gestational Weight Gain.

  • Gestational Weight Gain.
    American journal of obstetrics and gynecology, 2017
    Co-Authors: Michelle A. Kominiarek, Alan M. Peaceman
    Abstract:

    Prenatal care providers are advised to evaluate maternal Weight at each regularly scheduled prenatal visit, monitor progress toward meeting Weight Gain goals, and provide individualized counseling if significant deviations from a woman's goals occur. Today, nearly 50% of women exceed their Weight Gain goals with overWeight and obese women having the highest prevalence of excessive Weight Gain. Risks of inadequate Weight Gain include low birthWeight and failure to initiate breast-feeding whereas the risks of excessive Weight Gain include cesarean deliveries and postpartum Weight retention for the mother and large-for-Gestational-age infants, macrosomia, and childhood overWeight or obesity for the offspring. Prenatal care providers have many resources and tools to incorporate Weight and other health behavior counseling into routine prenatal practices. Because many women are motivated to improve health behaviors, pregnancy is often considered the optimal time to intervene for issues related to eating habits and physical activity to prevent excessive Weight Gain. Gestational Weight Gain is a potentially modifiable risk factor for a number of adverse maternal and neonatal outcomes and meta-analyses of randomized controlled trials report that diet or exercise interventions during pregnancy can help reduce excessive Weight Gain. However, health behavior interventions for Gestational Weight Gain have not significantly improved other maternal and neonatal outcomes and have limited effectiveness in overWeight and obese women.
