Guideline No. 391-Pregnancy and Maternal Obesity Part 1: Pre-conception and Prenatal Care

Association Between Maternal Body Mass Index and Fetal Acidosis in Term Twin Pregnancies: A Retrospective Cohort Study

OBJECTIVES

Given the increased risk of fetal acidosis in singleton neonates born to pregnant people with an elevated BMI, our objective was to evaluate the association between pre-pregnancy/first-trimester BMI and fetal acidosis among term twin pregnancies.

METHODS

Retrospective study of pregnant people with twin gestation and their term infants admitted to our centre between 2014 and 2019. Using a generalized estimating equation, the association between maternal BMI and fetal acidosis was determined using odds ratios (ORs) with 95% CIs. A two-sided P < 0.05 was considered significant.

RESULTS

A total of 275 pregnant people and 550 infants were analyzed. The number (%) of pregnancies in each BMI class were 10 (4%) underweight, 155 (56%) normal weight, 66 (24%) overweight, 22 (8%) class I, 9 (3%) class II, and 13 (5%) class III. The prevalence of maternal diabetes and hypertension was highest in class III (31%) and class II (44%), respectively. Fetal acidosis was diagnosed in 35 (6%) infants. After adjusting for confounders (maternal age, diabetes, and hypertension), infants born to those with elevated BMI did not have increased odds of fetal acidosis compared to those born to underweight and normal weight group (OR 1.29; 95% CI 0.38-4.41 for class I, P = 0.67 and OR 2.80; 95% CI 0.62-12.62 for the combined classes II and III, P = 0.18).

CONCLUSIONS

Maternal BMI was not associated with fetal acidosis in term twin pregnancies. Further research is required to corroborate study findings due to small sample size.

Maternal and long-term offspring outcomes of obesity during pregnancy

PURPOSE

Obesity`s prevalence is rising in women of reproductive age worldwide and has become the most common medical condition at this age group. Besides, its occurrence is also rising during pregnancy. This condition not only increases the risk of noncommunicable diseases on the mother, such as cardiovascular disease and diabetes, but also transfers this risk to the offspring.

METHODS

This is a narrative review based on scientific and review articles on the matter.

RESULTS

Obesity is associated with an increased risk of gestational diabetes mellitus, gestational hypertension and preeclampsia, venous thromboembolism, infection, and mental health problems. Furthermore, it has an impact on the progress of labor and induction matters. Regarding offspring outcomes, it is related to higher incidence of congenital anomalies, perinatal mortality, and the occurrence of large for gestational age newborns. Still, it has implications on cardiometabolic risk and neurodevelopment in offspring.

CONCLUSION

It is, therefore, imperative to encourage the adoption of healthy lifestyles, especially in the peri-conception and interpregnancy periods. Likewise, there must be support in the multidisciplinary monitoring of these pregnant women to minimize associated complication rates.

Clinical practice guidelines for the management of overweight and obesity published internationally: A scoping review

With the increasing prevalence of obesity placing additional demands on healthcare systems, many jurisdictions and professional bodies have developed clinical practice guidelines to support practitioners in the management of people with overweight and obesity. This scoping review aimed to identify key features of contemporary guidelines for the clinical management of overweight and obesity. Searches of MEDLINE, Guidelines International Network's international guidelines library, and other grey literature sources identified 38 guidelines of 18 countries and one region published since 2010. Guidelines were developed by committees (n = 36, 95%) that comprised knowledgeable experts (n = 36, 95%) and were multidisciplinary (n = 33, 87%), with limited consumer representation (n = 11, 29%). Guideline documentation incorporated review questions (n = 23, 61%), systematic reviews (n = 25, 66%), evidence grading systems (n = 33, 87%), processes for reaching consensus (n = 19, 50%), and guideline review details (n = 28, 74%). Treatment approaches included in most guidelines were nutrition and physical activity (n = 38, 100%), psychology (n = 37, 97%), pharmacotherapy (n = 32, 84%), and bariatric surgery (n = 31, 82%). Most guidelines targeted populations based on age (n = 30, 79%). Guidelines contained recommendations for pregnancy (n = 12, 32%), older adults (n = 9, 24%), and people with eating disorders (n = 8, 21%). Future guidelines would benefit from involvement of consumers including groups known to be at increased risk of overweight and obesity, targeted guidance for at risk groups, and consideration of weight bias and stigma.

The German guideline "Obesity in pregnancy": comparison with the international approach

BACKGROUND

Obesity is an increasing problem, even in young women of reproductive age. Obesity has a negative impact on conception, the course of pregnancy, and neonatal outcomes. Caring for obese pregnant women has becoming an important aspect of standard prenatal care. The Guideline "Obesity and Pregnancy" of the German Society of Gynecology and Obstetrics aims to create evidence-based recommendations which can be used to improve the care of obese pregnant women. As obesity is a worldwide problem, many societies for obstetrics and gynecology have created national guidelines.

METHODS

We reviewed the following guidelines for obesity and pregnancy: American College of Obstetricians and Gynecologists (ACOG) 2021, Royal College of Obstetrics and Gynecology (RCOG) 2018; AND Society of Obstetricians and Gynecologists of Canada (SOGC) 2019. These guidelines were compared to the German guideline.

RESULTS

There are some variations between the guidelines, though no major contradictions exist. Disparities were found regarding the recommendations for substitution of high folic acid and Vitamin D. Furthermore, the recommended time for screening for gestational diabetes and the methods to control fetal growth differ between the guidelines. Regarding place of birth, RCOG allows delivery in midwifery-led units in the absence of other high-risk circumstances, while others request facility of care by neonatologists and medical staff trained in care of obese women. Induction of labor at term due to increased risk of intrauterine demise is mostly limited to women with a body mass index of 40 kg/m2. Only one guideline considers induction of all obese women. For intrapartum management, the majority allows tolerating of longer labor times to delivery if fetal monitoring is sufficient and fetal stress is excluded. Special encouragement of breastfeeding and healthy lifestyle is commonly recommended; only in the Canadian guideline, postpartum depression evaluation is requested due to the overall high prevalence of depression and anxiety in obese women.

CONCLUSION

All guidelines consider pregnancies in obese women as high-risk pregnancies and emphasize the need for preconception counseling. There are special needs in pregnancy care and in the intrapartum and postpartum management to be observed.

Pairing Evidence-Based Strategies With Motivational Interviewing to Support Optimal Nutrition and Weight Gain in Pregnancy

OBJECTIVE

Because eating, nutrition, and weight management patterns adopted during pregnancy may persist beyond the postpartum period, pregnancy provides an opportunity for health education that affects the future health of the pregnant person, the fetus, and the family. This systematic review aimed to find nutrition and weight management behaviors that could be used safely during pregnancy to optimize gestational weight gain.

METHODS

PubMed, MEDLINE, and Web of Science were searched for research or systematic reviews published in English from 2018 to 2023 using terms including gestational weight gain maintenance, weight, management, pregnancy, behavior, strategy, and strategies. Excluded research used pediatric or adolescent populations, restrictive diets such as no carbohydrate or no fat diets, fasting, bariatric surgery, weight loss medications, private industry, or profit-earning programs using food brands or specific diet programs.

RESULTS

The abstracts reviewed in these areas: excessive gestational weight gain (1019), low-glycemic index diet (640), Mediterranean diet (220), MyPlate diet (2), the Dietary Approaches to Stop Hypertension (DASH) diet (50), portion control (6), home meal preparation (6), mindful eating (13), intuitive eating (10), self-weighing (10), and motivational interviewing during pregnancy (107), were reduced to 102 studies. Studies in those 10 areas were reviewed for nutrition and eating behaviors that are safe to use during pregnancy and could be used along with motivational interviewing.

CONCLUSION

Clinicians can discuss these behaviors using motivational interviewing techniques to assist clients in optimizing gestational weight gain. Dialogue examples pairing these strategies with motivational interviewing principles are included.

Evidence-Based Eating Patterns and Behavior Changes to Limit Excessive Gestational Weight Gain: A Scoping Review

BACKGROUND

International prenatal care guidelines set a standard for clinicians to discuss gestational weight gain with their patients along with the complications associated with prepregnancy obesity and excessive gestational weight gain. Clinicians often lack evidence-based eating, nutrition, and activity strategies to share with patients.

METHODS

This systematic review aimed to find eating patterns and behaviors that could be used safely during pregnancy to limit excessive gestational weight gain. PubMed, MEDLINE, and Web of Science were searched for research or systematic reviews performed in the United States or Canada and published in English from 2013 to 2023. Keyword search terms included weight, manage, behavior, strategy, strategies, gestational weight gain, and nutrition. Excluded research used pediatric or adolescent populations, restrictive diets, such as no carbohydrate or no fat diets, fasting, bariatric surgery, weight loss medications, private industry or profit-earning programs using food brands, or specific diet programs.

RESULTS

A total of 844 abstracts were retrieved, with 103 full-text studies reviewed. Behaviors had to be useful for maintaining a healthy gestational weight gain and had to be safe for use during pregnancy. Behaviors useful during pregnancy included meal planning, home meal preparation, portion control, using diets such as the Mediterranean diet, the low-glycemic index diet, and the Dietary Approaches to Stop Hypertension diet (DASH), regular physical activity, sleeping 6-7 h a night, mindful eating, intuitive eating, and regular seif-weighing.

CONCLUSION

The evidence-based strategies outlined in this review are safe for use during pregnancy and can assist patients in avoiding excessive gestational weight gain while maintaining the nutrition needed for healthy fetal growth.

Maternal Body Mass Index Trends and Weight Gain in Singleton Pregnancies at the Time of Fetal Anatomic Survey: Changes in the Last Decade and New Trends in the Modern Era

(1) Background: the worldwide impact of overweight and obesity is rising, increasingly resembling an epidemic (a price we have to pay for our new way of living). (2) Methods: our study aims to evaluate the temporal trends and patterns of singleton pregnant women's BMI (body mass index) in our region during a 12-year time frame between 2010 and 2021. (3) Results: We noticed a statistically significant difference between the BMIs of nulliparous and multiparous women and a significantly increased pregestational BMI in women with previous ART (assisted reproductive technology) procedures. Smoking pregnant women had a higher second trimester weight gain, regardless of parity. Women with folic acid supplementation alone had a higher BMI than those with folic acid and multivitamin intake. The weight of both nulliparous and multiparous women with chronic hypertension was statistically significantly higher in all three timeframes. Global weight gain did not reveal any statistically significant changes concerning women with pregestational diabetes, regardless of parity and the pregnancy trimester. (4) Conclusions: our article describes the trends in obesity and overweight in our middle-income country, in which this pathology is continuously growing, negatively influencing our reproductive-aged women and future generations.

A scoping review and critical evaluation of the methodological quality of clinical practice guidelines on nutrition in the preconception

Introduction

Clinical practice guidelines (CPGs) contain recommendations for specific clinical circumstances, including maternal malnutrition. This study aimed to identify the CPGs that provide recommendations for preventing, diagnosing, and treating women's malnutrition. Additionally, we sought to assess the methodological quality using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument.

Methods

An online search for CPGs was performed, looking for those that contained lifestyle and nutritional recommendations to prevent, diagnose and treat malnutrition in women during the preconception period using PubMed and different websites. The reviewers utilized the AGREE II instrument to appraise the quality of the CPGs. We defined high-quality guidelines with a final score of > 70%.

Results

The titles and abstracts from 30 guidelines were screened for inclusion, of which 20 guidelines were fully reviewed for quality assessment. The overall quality assessment of CPGs was 73%, and only 55% reached a high-quality classification. The domains in the guidelines classified as high-quality had the highest scores in "Scope and Purpose" and "Clarity of Presentation" with a median of 98.5 and 93%, respectively.

Discussion

Further assessment is needed to improve the quality of the guidelines, which is an opportunity to strengthen them, especially in the domains with the lowest scores.

Development and feasibility of a theory-guided and evidence-based physical activity intervention in pregnant women with high risk for gestational diabetes mellitus: a pilot clinical trial

BACKGROUND

Physical activity has been utilized as an effective strategy to prevent gestational diabetes mellitus (GDM). However, most pregnant women with high risk for GDM did not achieve the recommended physical activity level. Furthermore, relevant physical activity protocols have varied without theory-guided and evidence-based tailored to pregnant women with high risk for GDM. This study aimed to develop and pilot test a theory-guided and evidence-based physical activity intervention protocol for pregnant women with high risk for GDM.

METHODS

The study design was guided by the Medical Research Council Framework for Developing and Evaluating Complex Intervention (the MRC framework). The preliminary protocol for physical activity intervention was developed based on self-efficacy theory, research evidence identified from systematic reviews and clinic trials, stakeholder engagement, context, and economic considerations. The preliminary intervention protocol was validated through a content validity study by an expert panel of 10 experts. A single-blinded randomized controlled trial (RCT) was designed to test the feasibility and acceptability of the intervention.

RESULTS

The validity of the preliminary intervention protocol was excellent as consensus was achieved. The final 13 sessions of self-efficacy enhancing physical activity intervention protocol were developed, including knowledge education, exercise clinic visits and video, and group discussions with face-to-face and online blended sessions. In the feasibility study, 34 pregnant women with high risk for GDM were randomized for the intervention (n = 17) or the control group (n = 17). The recruitment and retention rates were 82.9% and 58.9%, respectively. Women in the intervention group had a lower incidence of GDM (26.7% vs. 36.5%) than the control group (P >0.05). All participants were satisfied with the intervention and agreed that the intervention was helpful.

CONCLUSIONS

The developed self-efficacy-enhancing physical activity intervention is a feasible and acceptable intervention for enhancing physical activity among pregnant women with high risk for GDM and is ready to be tested in a more extensive RCT study.

TRIAL REGISTRATION

The study was registered on 4 February 2022 (ChiCTR2200056355) by the Chinese Clini Trial Registry (CHiCTR).

Guideline No. 441: Antenatal Fetal Health Surveillance

OBJECTIVE

To summarize the current evidence and to make recommendations for antenatal fetal health surveillance (FHS) to detect perinatal risk factors and potential fetal decompensation in the antenatal period and to allow for timely intervention to prevent perinatal morbidity and/or mortality.

TARGET POPULATION

Pregnant individuals with or without maternal, fetal, or pregnancy-associated perinatal risk factors for antenatal fetal decompensation.

OPTIONS

To use basic and/or advanced antenatal testing modalities, based on risk factors for potential fetal decompensation.

OUTCOMES

Early identification of potential fetal decompensation allows for interventions that may support fetal adaptation to maintain well-being or expedite delivery.

BENEFITS, HARMS, AND COSTS

Antenatal FHS in pregnant individuals with identified perinatal risk factors may reduce the chance of adverse outcomes. Given the high false-positive rate, FHS may increase unnecessary interventions, which may result in harm, including parental anxiety, premature or operative birth, and increased use of health care resources. Optimization of surveillance protocols based on evidence-informed practice may improve perinatal outcomes and reduce harm.

EVIDENCE

Medline, PubMed, Embase, and the Cochrane Library were searched from inception to January 2022, using medical subject headings (MeSH) and key words related to pregnancy, fetal monitoring, fetal movement, stillbirth, pregnancy complications, and fetal sonography. This document represents an abstraction of the evidence rather than a methodological review.

VALIDATION METHODS

The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations).

INTENDED AUDIENCE

All health care team members who provide care for or education to obstetrical patients, including maternal fetal medicine specialists, obstetricians, family physicians, midwives, nurses, nurse practitioners, and radiologists.

Directive clinique no 441 : Surveillance prénatale du bien-être fœtal

OBJECTIF

Résumer les données probantes actuelles et formuler des recommandations pour la surveillance prénatale du bien-être fœtal afin de détecter les facteurs de risque périnatal et toute potentielle décompensation fœtale et de permettre une intervention rapide en prévention de la morbidité et la mortalité périnatales.

POPULATION CIBLE

Personnes enceintes avec ou sans facteurs maternels, fœtaux ou gravidiques associés à des risques périnataux et à la décompensation fœtale.

OPTIONS

Utiliser des examens prénataux par technologie de base et/ou avancée en fonction des facteurs de risque de décompensation fœtale. RéSULTATS: La reconnaissance précoce de toute décompensation fœtale potentielle permet d'intervenir de façon à favoriser l'adaptation fœtale pour maintenir le bien-être ou à accélérer l'accouchement. BéNéFICES, RISQUES ET COûTS: Chez les personnes enceintes ayant des facteurs de risque périnatal confirmés, la surveillance du bien-être fœtal contribue à réduire le risque d'issue défavorable. Compte tenu du taux élevé de faux positifs, la surveillance du bien-être fœtal peut augmenter le risque d'interventions inutiles, ce qui peut avoir des effets nuisibles, dont l'anxiété parentale, l'accouchement prématuré ou assisté et l'utilisation accrue des ressources de soins de santé. L'optimisation des protocoles de surveillance d'après des pratiques fondées sur des données probantes peut améliorer les issues périnatales et réduire les effets nuisibles. DONNéES PROBANTES: Des recherches ont été effectuées dans les bases de données Medline, PubMed, Embase et Cochrane Library, de leur création jusqu'à janvier 2022, à partir de termes MeSH et de mots clés liés à la grossesse, à la surveillance fœtale, aux mouvements fœtaux, à la mortinaissance, aux complications de grossesse et à l'échographie fœtale. Le présent document est un résumé des données probantes et non pas une revue méthodologique.

Clinical analysis of diabetes in pregnancy with stillbirth

We analyzed the clinical characteristics of patients with diabetes in pregnancy (DIP) associated with stillbirth and explored strategies to reduce its incidence. We retrospectively analyzed 71 stillbirths associated with DIP (group A) and 150 normal pregnancies (group B) during 2009 to 2018. The incidence of the following was higher in group A (P < .05): hypertensive disorders (38.03% vs 6.00%), placenta previa (14.08% vs 2.67%), placental abruption (5.63% vs 0.67%), fetal malformation (8.45% vs 0.67%), fasting plasma glucose (FPG) ≥ 7.0 mmol/L (46.48% vs 0.67%), 2-h postprandial plasma glucose ≥ 11.1 mmol/L (57.75% vs 6.00%), HbA1c ≥ 6.5% (63.38% vs 6.00%), and polyhydramnios (11.27% vs 4.67). The incidence of oligohydramnios (4.23% vs 6.67%) was lower in group A than in group B (P < .05). According to the gestational age at the time of stillbirth, Group-A cases were subgrouped into miscarriages (20-27+6 weeks), premature deliveries (28-36+6 weeks), and full-term deliveries (≥37 weeks). Age, parity, and DIP type did not differ among the subgroups (P > .05). Among patients with DIP, antenatal FPG, 2-h postprandial plasma glucose, and HbA1c were significantly associated with stillbirth (P < .05). Stillbirth was first detected at 22 weeks and typically occurred at 28-36+6 weeks. DIP was associated with a higher incidence of stillbirth, and FPG, 2-h postprandial plasma glucose, and HbA1c were potential indicators of stillbirth in DIP. Age (odds ratio [OR]: 2.21, 95% confidence interval [CI]: 1.67-2.74), gestational hypertension (OR: 3.44, 95% CI: 2.21-4.67), body mass index (OR: 2.86, 95% CI: 1.95-3.76), preeclampsia (OR: 2.29, 95% CI: 1.45-3.12), and diabetic ketoacidosis (OR: 3.99, 95% CI: 1.22-6.76) were positively correlated with the occurrence of stillbirth in DIP. Controlling perinatal plasma glucose, accurately detecting and managing comorbidities/complications, and timely termination of pregnancy can reduce the incidence of stillbirths associated with DIP.

Prevention of pre-eclampsia with aspirin: A systematic review of guidelines and evaluation of the quality of recommendation evidence

BACKGROUND

Evidence has shown significant benefits of aspirin for preventing pre-eclampsia.

OBJECTIVES

The objective of this study was to systematically review recommendations from clinical practice guidelines and other recommendation documents on aspirin for the prevention of pre-eclampsia.

SEARCH STRATEGY

Ten databases were searched for statements from December 1, 2013, to January 1, 2022.

SELECTION CRITERIA

Without language restrictions, the most recent version of documents was considered.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted recommendations. Guideline quality was assessed using a modified AGREE-II instrument and the AGREE-REX tool.

MAIN RESULTS

Out of 48 statements on the prevention of pre-eclampsia, 46 had recommendations on use of aspirin. Of them, 39 were supported by evidence from systematic reviews or randomized controlled trials. Three statements reported aspirin's significant reductions in preterm pre-eclampsia and one in perinatal death. Concerning quality, 41% of statements were rated as high quality in all domains of the AGREE-II tool, 15% were rated high quality in all domains of the AGREE-REX tool, and 11% were rated high quality in all domains on both tools.

CONCLUSIONS

While 96% of statements advocated for use of aspirin, only 9% reported a significant reduction in preterm pre-eclampsia or perinatal death. Based on the AGREE tools, future statements could use methodological improvement.

Exploring body dissatisfaction in pregnancy and the association with gestational weight gain, obesity, and weight stigma

OBJECTIVE

Body dissatisfaction in pregnancy has been associated with negative psychological maternal outcomes, including increased risk of postpartum depression. This study aimed to explore weight-related factors that influence body dissatisfaction in pregnancy, including gestational weight gain (GWG), weight stigma, obesity, and weight loss attempts before pregnancy.

DESIGN

Secondary analysis of a larger cross-sectional study.

SETTING

Online survey administered via Qualtrics.

PARTICIPANTS

≥12 weeks pregnant, ≥18 years of age, having a singleton pregnancy and residing in Canada.

MEASUREMENTS AND FINDINGS

A battery of questionnaires were completed, including the Body Image in Pregnancy Scale (BIPS) sub-scale. The BIPS scores were compared based on experiences of weight stigma in pregnancy, perception towards their GWG, weight loss attempts before pregnancy, obesity, and GWG category classified as excessive or not referring to Institute of Medicine (2009) guidelines. Significant differences were entered into a linear regression model with BIPS scores as the dependent variable. Significance was accepted as p<0.05. A total of 182 participants completed the survey. There were no differences in BIPS scores based on GWG category (p = 0.160), or obesity (p = 0.230). Poorer BIPS scores were reported by those who felt they had gained 'too much' pregnancy weight than 'appropriate' (p<0.001), and among those who were trying to lose weight before pregnancy compared to those who were not (p = 0.002). Poorer BIPS scores were also reported by individuals who indicated they had experienced weight stigma during pregnancy compared to those who had not (p<0.001). Regression results showed that significant variables were perceptions towards GWG (p = 0.003) and experiencing weight stigma in pregnancy (p = 0.011).

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Perceptions towards GWG and experiencing weight stigma can influence body dissatisfaction in pregnancy. Given the detrimental physical and psychological consequences of body dissatisfaction, effective strategies to reduce prenatal weight stigma are needed, such as training maternal healthcare providers to offer sensitive preconception and prenatal weight counselling.

Obesity in Pregnancy: A Comprehensive Review of Influential Guidelines

Importance

Obesity is one of the most common clinical entities complicating pregnancies and is associated with short- and long-term consequences for both the mother and the offspring.

Objective

The aim of this study were to review and compare the most recently published influential guidelines on the management of maternal obesity in the preconceptional, antenatal, intrapartum, and postpartum period.

Evidence Acquisition

A descriptive review of guidelines from the American College of Obstetricians and Gynecologists, the International Federation of Gynecology and Obstetrics, the Society of Obstetricians and Gynecologists of Canada, the Royal College of Obstetricians and Gynecologists, and the Royal Australian and New Zealand College of Obstetricians and Gynecologists on obesity in pregnancy was carried out.

Results

There is an overall agreement among the reviewed guidelines regarding the importance of prepregnancy weight loss with behavioral modification, optimization of gestational weight gain, and screening for comorbidities in improving pregnancy outcomes of obese women. Women with previous bariatric surgery should be screened for nutritional deficiencies and have a closer antenatal surveillance, according to all guidelines. In addition, folic acid supplementation is recommended for 1 to 3 months before conception and during the first trimester, but several discrepancies were identified with regard to other vitamins, iodine, calcium, and iron supplementation. All medical societies recommend early screening for gestational diabetes mellitus and early anesthetic assessment in obese women and suggest the use of aspirin for the prevention of preeclampsia when additional risk factors are present, although the optimal dosage is controversial. The International Federation of Gynecology and Obstetrics, Society of Obstetricians and Gynecologists of Canada, Royal College of Obstetricians and Gynecologists, and Royal Australian and New Zealand College of Obstetricians and Gynecologists point out that specific equipment and adequate resources must be readily available in all health care facilities managing obese pregnant women. Moreover, thromboprophylaxis and prophylactic antibiotics are indicated in case of cesarean delivery, and intrapartum fetal monitoring is justified during active labor in obese patients. However, there are no consistent protocols regarding the fetal surveillance, the monitoring of multiple gestations, the timing and mode of delivery, and the postpartum follow-up, although weight loss and breastfeeding are unanimously supported.

Conclusions

Obesity in pregnancy is a significant contributor to maternal and perinatal morbidity with a constantly rising global prevalence among reproductive-aged women. Thus, the development of uniform international protocols for the effective management of obese women is of paramount importance to safely guide clinical practice and subsequently improve pregnancy outcomes.

The effects of a midwife-led weight management program for pregnant women: A randomized controlled trial

BACKGROUND

Inappropriate weight gain during pregnancy may present risks for maternal and newborn health. Pregnancy is considered the optimal time to intervene on women's health behaviors such as eating habits and physical activity. However, current clinical practice guidelines for weight management during pregnancy were not fully based on randomized trials, thus lacking specific "active intervention ingredients" that are proven effective in achieving appropriate gestational weight gain. Therefore it is essential to develop and implement an evidence-based weight management program for pregnant women.

OBJECTIVE

To examine the effects of a midwife-led weight management program on improving appropriate gestational weight gain, health literacy, experience of antenatal care, and maternal and neonatal outcomes among Chinese pregnant women.

DESIGN

A two-group randomized controlled trial.

SETTINGS AND PARTICIPANTS

A total of 426 pregnant women were recruited from a tertiary women's hospital in eastern China.

METHODS

Participants were randomly allocated to either intervention group (n = 213) or control group (n = 213). Women in the intervention group participated in a midwife-led weight management program during pregnancy, while women in the control group received the conventional obstetrician-led antenatal care. We assessed women at the first antenatal contact, 35-36 weeks gestation and 2-3 days postpartum. Data on gestational weight gain, health literacy, experience of antenatal care, and maternal and neonatal outcomes were compared between the two groups. Dummy variable analysis was conducted to reveal the effect of weight management program on gestational weight gain.

RESULTS

The overall gestational weight gain between the two groups was not statistically different (t = -1.377, P = 0.170). Compared with women in the control group, the odds of having inappropriate gestational weight gain was lower in the intervention group (OR = 0.270, 95%CI 0.169, 0.431). Further subgroup analyses showed that women in the intervention group had lower risk of inadequate gestational weight gain (OR = 0.305, 95%CI 0.180, 0.515) and excessive gestational weight gain (OR = 0.236, 95%CI 0.138, 0.404) than those in the control group. The score of experience of antenatal care was significantly higher in the midwife-led weight management group than that in the control group (193.70 ± 18.51 versus 165.70 ± 28.23, P < 0.001). Women's health literacy score was higher in the intervention group than control group [74.41 (69.57, 81.77) versus 71.88 (66.23, 77.18), P = 0.004].

CONCLUSION

Compared with the conventional antenatal care, the midwife-led weight management program could facilitate appropriate gestational weight gain, enhance health literacy, and promote positive experience of antenatal care for Chinese pregnant women.

Optimal Gestational Weight Gain for Women With Obesity

OBJECTIVE

To determine the optimal gestational weight gain interval for women with obesity in order to minimize neonatal and maternal adverse events.

METHODS

Secondary analysis of the QUARISMA trial, including women with obesity who delivered a full-term singleton in cephalic presentation from 2008 to 2011 in Québec. The primary outcome was a composite risk of major neonatal morbidity. Secondary outcomes were composite risks of major maternal morbidity, minor neonatal and maternal morbidity, and cesarean delivery. Various ranges of weight gain were compared with the current recommendations (reference group) using logistic regression to identify an optimal gestational weight gain interval. In a secondary analysis, women with obesity were stratified by obesity class (I-III).

RESULTS

Among 16 808 eligible women with obesity, 3270 gained less weight than recommended, 4355 gained weight as recommended (5-9.09 kg), and 9183 gained more weight than recommended. Optimal gestational weight change for all women with obesity was -1 to +4 kg and was associated with reduced risk of major neonatal morbidity (aOR 0.49; 95%CI 0.33-0.73, P < 0.001) compared with the reference group. Analysis by class of obesity showed a reduced risk of major neonatal morbidity with a weight change of -1 to +4 kg for class I, -2 to +2 for class II), and -2 to +3 kg for class III.

CONCLUSION

Compared with the current guidelines, a gestational weight change of -1 to +4 kg is associated with reduced risk of adverse perinatal outcomes. While similar findings were seen among women with class I obesity, women with class II or III obesity could benefit from a lower weight gain.

Quality Appraisal of Nutritional Guidelines to Prevent, Diagnose, and Treat Malnutrition in All Its Forms during Pregnancy

This work aimed to identify clinical practice guidelines (CPGs) that include recommendations for the prevention, diagnosis, and treatment of women’s malnutrition during pregnancy and to evaluate the quality of these guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. We conducted a literature review using PubMed and different websites from January 2009 to February 2021. The quality of the CPGs was independently assessed by reviewers using the AGREE II instrument, which defines guidelines scoring >70% in the overall assessment as “high quality”. The analysis included 43 guidelines. Among the main findings, we identified that only half of the CPGs (51.1%) obtained a final “high quality” evaluation. AGREE II results varied widely across domains and categories. The two domains that obtained the highest scores were scope and purpose with 88.3% (range 39 to 100%) and clarity of presentation with 87.2% (range 25 to 100%). Among the “high quality” CPGs, the best scores were achieved by the three guidelines published by the National Institute of Health and Care Excellence (NICE) and the World Health Organization (WHO). Due to the importance of maternal nutrition in pregnancy, it is essential to join forces to improve the quality of the guidelines, especially in CPGs that do not meet the reference standards for quality.

Association between maternal adiposity measures and infant health outcomes: A systematic review and meta-analysis

Maternal obesity increases risks of adverse fetal and infant outcomes. Guidelines use body mass index to diagnose maternal obesity. Evidence suggests body fat distribution might better predict individual risk, but there is a lack of robust evidence during pregnancy. We explored associations between maternal adiposity and infant health. Searches included six databases, references, citations, and contacting authors. Screening and quality assessment were carried out by two authors independently. Random effects meta-analysis and narrative synthesis were conducted. We included 34 studies (n = 40,143 pregnancies). Meta-analysis showed a significant association between maternal fat-free mass and birthweight (average effect [AE] 18.07 g, 95%CI 12.75, 23.38) but not fat mass (AE 8.76 g, 95%CI -4.84, 22.36). Women with macrosomic infants had higher waist circumference than controls (mean difference 4.93 cm, 95% confidence interval [CI] 1.05, 8.82). There was no significant association between subcutaneous fat and large for gestational age (odds ratio 1.06 95% CI 0.91, 1.25). Waist-to-hip ratio, neck circumference, skinfolds, and visceral fat were significantly associated with several infant outcomes including small for gestational age, preterm delivery, neonatal morbidity, and mortality, although meta-analysis was not possible for these variables. Our findings suggest that some measures of maternal adiposity may be useful for risk prediction of infant outcomes. Individual participant data meta-analysis could overcome some limitations in our ability to pool published data.

Association between maternal adiposity measures and adverse maternal outcomes of pregnancy: Systematic review and meta-analysis

Maternal obesity increases pregnancy-related risks. Women with a body mass index (BMI) ≥ 30 kg/m2 are considered to be at risk and should receive additional care, although approximately half will have uncomplicated pregnancies. This systematic review aimed to identify early pregnancy measures of adiposity associated with adverse maternal health outcomes. Searches included six databases, reference lists, citations, and contacting authors. Screening and quality assessment were carried out by two authors independently. Random effects meta-analysis and narrative synthesis were conducted. Seventy studies were included with a pooled sample of 89,588 women. Meta-analysis showed significantly increased odds of gestational diabetes mellitus (GDM) with higher waist circumference (WC) categories (1.40, 95% confidence interval [CI] 1.04, 1.88) and per unit increase in WC (1.31, 95% CI 1.03, 1.67). Women with GDM had higher WC than controls (mean difference [MD] 6.18 cm, 95% CI 3.92, 8.44). WC was significantly associated with hypertensive disorders, delivery-related outcomes, metabolic syndrome, and composite pregnancy outcomes. Waist to hip ratio was significantly associated with GDM, hypertensive disorders, and delivery-related outcomes. Fat mass, neck circumference, skinfolds, and visceral fat were significantly associated with adverse outcomes, although limited data were available. Our findings identify the need to explore how useful adiposity measures are at predicting risk in pregnancy, compared with BMI, to direct care to women with the greatest need.

RECOMMANDATIONS

Guideline No. 426: Hypertensive Disorders of Pregnancy: Diagnosis, Prediction, Prevention, and Management

OBJECTIVE

This guideline was developed by maternity care providers from obstetrics and internal medicine. It reviews the diagnosis, evaluation, and management of the hypertensive disorders of pregnancy (HDPs), the prediction and prevention of preeclampsia, and the postpartum care of women with a previous HDP.

TARGET POPULATION

Pregnant women.

BENEFITS, HARMS, AND COSTS

Implementation of the recommendations in these guidelines may reduce the incidence of the HDPs, particularly preeclampsia, and associated adverse outcomes.

EVIDENCE

A comprehensive literature review was updated to December 2020, following the same methods as for previous Society of Obstetricians and Gynaecologists of Canada (SOGC) HDP guidelines, and references were restricted to English or French. To support recommendations for therapies, we prioritized randomized controlled trials and systematic reviews (if available), and evaluated substantive clinical outcomes for mothers and babies.

VALIDATION METHODS

The authors agreed on the content and recommendations through consensus and responded to peer review by the SOGC Maternal Fetal Medicine Committee. The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, along with the option of designating a recommendation as a "good practice point." See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional [weak] recommendations).The Board of the SOGC approved the final draft for publication.

INTENDED USERS

All health care providers (obstetricians, family doctors, midwives, nurses, and anesthesiologists) who provide care to women before, during, or after pregnancy.

RECOMMENDATIONS

Management of cardiovascular risk factors during pregnancy

Cardiovascular (CV) risk factors are rising among women of reproductive age. Obesity, hyperlipidaemia, diabetes, and hypertension are associated with adverse pregnancy outcomes and increased CV disease (CVD) risk following pregnancy. Pre-conception counselling and longitudinal postpartum follow-up with ongoing CV risk factor screening are critical for early CVD prevention, though significant racial/ethnic disparities in access to care result in significant gaps. This review summarises the recommended management of CV risk factors during and after pregnancy. For obesity, prevention of excessive weight gain is critical. Except in rare cases, lipid-lowering therapies for women with hyperlipidaemia should be stopped before pregnancy. Women with diabetes in pregnancy should maintain tight glucose control, with hemolgobin A1c (HbA1c) <6.5% to prevent congenital abnormalities. Hypertensive disorders of pregnancy are associated with high maternal and neonatal morbidity and require long-term follow-up to prevent future CVD. Finally, this review highlights the lack of clinical trials informing optimal treatment strategies of CV risk factors during and after pregnancy. Further research is needed to better understand how to improve long-term CV health among this high-risk population.

Does prepregnancy weight change have an effect on subsequent pregnancy health outcomes? A systematic review and meta-analysis

International guidelines recommend women with an overweight or obese body mass index (BMI) aim to reduce their body weight prior to conception to minimize the risk of adverse perinatal outcomes. Recent systematic reviews have demonstrated that interpregnancy weight gain increases women's risk of developing adverse pregnancy outcomes in their subsequent pregnancy. Interpregnancy weight change studies exclude nulliparous women. This systematic review and meta-analysis was conducted following MOOSE guidelines and summarizes the evidence of the impact of preconception and interpregnancy weight change on perinatal outcomes for women regardless of parity. Sixty one studies met the inclusion criteria for this review and reported 34 different outcomes. We identified a significantly increased risk of gestational diabetes (OR 1.88, 95% CI 1.66, 2.14, I²  = 87.8%), hypertensive disorders (OR 1.46 95% CI 1.12, 1.91, I²  = 94.9%), preeclampsia (OR 1.92 95% CI 1.55, 2.37, I²  = 93.6%), and large-for-gestational-age (OR 1.36, 95% CI 1.25, 1.49, I²  = 92.2%) with preconception and interpregnancy weight gain. Interpregnancy weight loss only was significantly associated with increased risk for small-for-gestational-age (OR 1.29 95% CI 1.11, 1.50, I²  = 89.9%) and preterm birth (OR 1.06 95% CI 1.00, 1.13, I²  = 22.4%). Our findings illustrate the need for effective preconception and interpregnancy weight management support to improve pregnancy outcomes in subsequent pregnancies.

Midwives perceptions of managing pregnancies complicated by obesity: A mixed methods study

OBJECTIVE

The growing prevalence of obesity is a concern for midwives. In Canada, the absence of regulatory standards, varying protocols and consultant preferences shape clinical decision making for the midwife and may lead to inconsistent practice. Our aim was to understand the barriers, enablers, and knowledge gaps that influenced experiences of midwives in Ontario, Canada when providing care to clients impacted by obesity.

METHODS

Mixed methods design using a sequential, explanatory approach. Surveys conducted with midwives were administered using an online platform, followed by semi-structured interviews to understand the perspectives elicited in the survey in greater detail. Interviews were audio recorded and transcribed verbatim. Survey data were analyzed using descriptive statistics, and thematic analysis was used for generating codes, categories and themes from the interview data.

RESULTS

144 midwives completed the survey and 20 participated in an interview. The participants described their clinical management when caring for those with obesity which included considerations regarding additional tests/investigations, consultation and transfer of care, and place of birth. Up to 93% of surveyed midwives believed that clients with obesity were appropriate for midwifery-led care however there was less certainty about suitability as BMI increased to higher ranges such as > 45). The care management was influenced by beliefs and attitudes, knowledge, and system-level factors. Midwives experienced barriers such as inconsistent practices and role confusion, and felt ill equipped to care for pregnancies affected by obesity due to unclear guidelines.

CONCLUSIONS

Overall, midwives believe clients with obesity are suitable for midwifery-led care due to its individualized, non-judgmental approach to care. Additional training for midwives and other obstetric care providers would be beneficial to help overcome barriers in providing effective care to pregnancies affected by obesity.

Weight stigma and prenatal physical activity: Exploring the perspectives of pregnant women living with obesity

OBJECTIVE

To identify sources of weight stigma in physical activity (PA)-related milieus reported by pregnant women living with obesity. We also report person-informed strategies to improve the delivery of PA promotions and prescriptions to prevent weight stigma and improve maternal PA.

DESIGN

This is a qualitative descriptive study and semi-structured interviews were conducted.

SETTING AND PARTICIPANTS

Purposive sampling including pregnant women living with obesity, with a body mass index ≥35.0 kg/m², ≥18 years of age, and receiving specialized prenatal care were recruited from an obstetrics clinic in Kingston, Canada.

MEASUREMENT AND FINDINGS

Data were assessed by a content analysis, whereby coded themes represented sources of weight stigma related to prenatal PA. Demographic characteristics (pre-pregnancy body mass index, age, gestational age) were summarized and presented as means and standard deviations. In-depth interview data were collected from eight women. Average pre-pregnancy BMI, age, and gestational age were 44.6±4.8 kg/m², 32.0±4.1 years, 31.1±5.8 weeks, respectively. Two sources of weight stigma related to prenatal PA were identified: 1. Lack of visual representation - online images and images found in exercise promotional material do not include women who have obesity; 2. Lack of individualized recommendations - currently available prenatal PA guidelines and/or recommendations from healthcare providers do not always consider individual physical barriers or health goals women may have.

KEY CONCLUSION AND IMPLICATIONS FOR PRACTICE

By increasing body positive representation of pregnant women exercising and offering person-centered prenatal PA recommendations, maternal PA may improve including women living with obesity. Findings from this work can inform future PA interventions, health promotion programming, and prescriptions from prenatal care providers to implement person-oriented strategies to prevent weight stigma and improve the delivery of care for pregnant women living with obesity.

Weight management across preconception, pregnancy, and postpartum: A systematic review and quality appraisal of international clinical practice guidelines

This systematic review and quality appraisal evaluated clinical practice guidelines (CPGs) for weight management and weight-related behaviors across preconception, pregnancy, and postpartum. CPGs published in English were identified from research and guideline-specific databases between 2010 and 2019. Recommendations were categorized into weight (body mass index screening, weight loss, weight gain prevention, and gestational weight gain), diet, food safety, physical activity, and behavioral strategies. Three independent appraisers assessed CPG quality using the Appraisal of Guidelines Research and Evaluation II instrument. Twenty-two CPGs were included across preconception (n = 2), pregnancy (n = 8), postpartum (n = 2), or a combination (n = 10). Overall, 45% of CPGs were appraised as poor quality, 32% as moderate, and 23% as high. Evaluation of body mass index and supplementation recommendations were most common across CPGs, alongside secondary weight management recommendations for women with obesity in fewer CPGs. Accompanying recommendations for diet, physical activity, and behavior were highly variable between guidelines. We report significant ambiguity in existing guidance and an absence of important considerations, including targeting weight gain prevention and limiting excess gestational weight gain. Results emphasize the need for development of robust, comprehensive, and high quality guidelines on healthy lifestyle and weight management across these formative reproductive life stages.

Women's Views on Advice About Weight Gain in Pregnancy: A Grounded Theory Study

OBJECTIVES

Pregnant women prioritize the health of their pregnancy, and weight gain contributes to the pregnancy's health. Women encounter different messages about gestational weight gain from various sources that can be confusing. This study aimed to increase our understanding of the processes influencing how women experience the gestational weight gain advice they receive.

METHODS

Grounded theory methodology was chosen. Women receiving prenatal care in a primary care setting were invited to participate in one-on-one interviews.

RESULTS

All fifteen participants had high educational attainment, fourteen were Caucasian, and five had an elevated pre-pregnancy body mass index. Six interconnected themes emerged from the data: (1) striving to have a healthy pregnancy; (2) experiencing influences; (3) feeling worried; (4) Managing ambiguity; (5) trusting a source of information; and (6) feeling relief.

CONCLUSIONS FOR PRACTICE

Physicians are perceived by pregnant women to be a source of trusted information about gestational weight gain and are therefore in a strategic position to help women achieve healthy weight gain during pregnancy.

Micronutrient screening, monitoring, and supplementation in pregnancy after bariatric surgery

We present the case of a woman with a history of biliopancreatic diversion and duodenal switch procedure who developed severe malnourishment requiring total parenteral nutrition during three pregnancies. The widespread use of bariatric surgery, particularly among those of reproductive age, has led to an increase in the number of women who become pregnant following bariatric surgery. There is a paucity of evidence to guide nutritional recommendations for women during pregnancy post bariatric surgery. We review this literature and summarize key published evidence and provide comprehensive recommendations concerning the common challenges in the management of nutrition status during pregnancy. The focus is on the impact of malabsorptive bariatric surgeries on pregnancy outcomes, nutrient deficiencies, recommendations for micro- and macronutrient monitoring and supplementation, and altered glucose metabolism and implications for diabetes screening. Optimizing pregnancy outcomes for individuals following bariatric surgery requires multidisciplinary team management including obstetrical providers, obstetric medicine specialists, and dietitians.

Women's Suggestions for How To Reduce Weight Stigma in Prenatal Clinical Settings

OBJECTIVE

To describe the experiences of weight stigma in prenatal clinical settings among high-risk pregnant women living with obesity and to obtain women's perspectives regarding changes to prenatal health care practices that may reduce weight stigma.

DESIGN

Qualitative descriptive study.

SETTING/LOCAL PROBLEM

High-risk obstetrics clinic. Weight stigma experienced in prenatal clinical settings can negatively influence maternal health and well-being as well as communication with health care providers.

PARTICIPANTS

Nine pregnant women with obesity who were receiving specialized prenatal care in their third trimester.

INTERVENTION/MEASUREMENTS

Women participated in semistructured telephone interviews. Data were inductively analyzed using a content analysis, whereby coded data were organized to represent experiences of or suggestions provided by pregnant women to reduce weight stigma in prenatal clinical settings.

RESULTS

Experiences of weight stigma included poor communication, generalizations made about health and lifestyle behaviors, and focusing only on excess body weight during clinical appointments as the cause of negative health outcomes. To reduce weight stigma, women suggested that health care providers practice sensitive communication, offer individualized care for weight management, and reduce the focus on body weight by also independently addressing comorbidities or other health indicators.

CONCLUSION

Women interviewed for this study provided suggestions that can be implemented in prenatal clinical settings to reduce weight stigma and improve the delivery of equitable health care.

Impact of Obesity on Outcomes of Pregnancy in Women With Heart Disease

BACKGROUND

Women with heart disease are at risk for complications during pregnancy. This study sought to examine the effect of maternal obesity on pregnancy complications in women with heart disease.

OBJECTIVES

The objective was to determine the incidence of adverse cardiac events (CE) in pregnant women with heart disease and obesity.

METHODS

Adverse CE during pregnancy were examined in a prospective cohort of women with heart disease. CE were a composite of the following: cardiac death/arrest, arrhythmias, heart failure, myocardial infarction, stroke, aortic dissection, and thromboembolic events. Pre-eclampsia and post-partum hemorrhage were also studied. Outcomes were examined according to body mass index (BMI). To identify additional predictors of CE, a baseline risk score (CARPREG [Canadian Cardiac Disease in Pregnancy Study] II score) for predicting cardiac complications was calculated for all pregnancies and included in a multivariable logistic regression model.

RESULTS

Of 790 pregnancies, 19% occurred in women with BMI ≥30 kg/m² (obesity), 25% in women with BMI 25 to 29.9 kg/m² (overweight), 53% in women with BMI 18.5 to 24.9 kg/m² (normal weight), and 3% in women with BMI <18.5 kg/m² (underweight). Women with obesity were at higher risk of CE when compared with women with normal weight (23% vs. 14%; p = 0.006). In a multivariable model, obesity (odds ratio: 1.7; 95% confidence interval: 1.0 to 2.7) and higher CARPREG II risk scores (odds ratio: 1.7; 95% confidence interval: 1.5 to 1.9) predicted CE. Pre-eclampsia was more frequent in women with obesity compared with those with normal weight (8% vs. 2%; p = 0.001).

CONCLUSIONS

Obesity increases the risk of maternal cardiovascular complications in pregnant women with heart disease. This modifiable risk factor should be addressed at the time of preconception counseling.
