Obstetrician/Gynecologists' Knowledge, Attitudes, and Practices Regarding Weight Gain During Pregnancy

Does a video module improve patient adherence to recommended gestational weight gain guidelines?

OBJECTIVES

We aim to assess if implementation of an educational video module can improve patient adherence to recommended weight gain guidelines. Secondarily, we investigated if patients' knowledge about gestational weight gain was improved with use of the video, as well as if there was a difference in maternal and neonatal outcomes, and patient satisfaction.

METHODS

This was an IRB-approved, prospective cohort study conducted from February 2019 to October 2019. Patients were recruited from a large academic practice during their first trimester of pregnancy. Patients in the control cohort received routine care. Patients in the video cohort watched a 5-min educational video module about gestational weight gain. Pre-pregnancy weight and baseline demographics were recorded. All patients took a baseline questionnaire assessing gestational weight gain knowledge upon enrollment, and again 4 weeks later. Pre and post score differences were calculated. On admission to the hospital for delivery, all patients' gestational weight gain was calculated, and the overall gestational weight gain differences between the two groups were calculated. Maternal and neonatal delivery outcomes were also collected. T-tests, Mann-Whitney U tests, and Chi-square analyses were used to compare groups, and a p-value of <.05 was deemed statistically significant.

RESULTS

During the study period, 155 patients were recruited, with 79 in control cohort and 76 in video cohort, respectively. There was no significant difference in the percentage of patients who gained the appropriate amount of weight between the two groups; 25% (18/74) of patients in the control vs. 25% (17/68) of patients in video cohort (p = .926). There was no difference in the improvement of the pre and post assessment scores when compared between the two cohorts; the average score improvement was 1.72 ± 15.09% for the control, vs. 6.20 ± 12.51% for video cohort (p = .129). There was no difference in maternal or neonatal outcomes between the two groups. Patients were overall satisfied with the video module, with 67.6% (n = 45) reporting the video to be very educational.

CONCLUSIONS

Use of a video module did not improve GWG outcomes or knowledge in our study. Future work can focus on use of a recurring intervention throughout pregnancy, either with app-based technology or multiple videos.

Assessing Health Care Providers' Knowledge and Practices of Nutrition during Pregnancy in Lebanon: A Cross-Sectional Study

Background and objectives: Health care professionals (HCPs) are well-positioned to discuss healthy behaviors during pregnancy, but the published research of prenatal healthcare providers' knowledge about the significance of nutrition during pregnancy in Lebanon is scarce. The purpose of this study was to explore the knowledge, attitudes, and practices of Lebanese prenatal healthcare providers towards nutrition during pregnancy. Materials and Methods: A cross-sectional study using an online questionnaire was conducted. Health care providers were contacted by phone and email to participate in the online survey. A list of all clinics providing antenatal health services was obtained from the Order of Physicians and the Order of Midwives. A multistage random sample was selected. In the first stage, it was stratified per region (Beirut center or suburbs, and the southern region). In the second phase, it was stratified per clinic type (private, primary healthcare center, or hospital). Gynecologists and midwives who are members of the Order of Physicians and the Order of Midwives (n = 1333), were included. Results: Two-hundred and six responses (55% males) were obtained. Approximately 44% of the HCP were aged 50 and older, and 68.4% had more than 10 years of work experience. HCPs from Beirut represented 41.3% of the respondents. Eighty-eight percent of the HCPs were physicians, and 11% were midwives. The majority of the participants considered nutrition during pregnancy to be very important. Furthermore, half of these participants considered their position in delivering nutrition information as very significant. Most of the respondents reported that they provide nutrition advice to pregnant women, and they also received nutrition education during their profession. However, they perceived their nutrition knowledge as inadequate. Conclusion: Health care providers' attitude towards the importance of maternal nutrition and their confidence in talking about nutrition-related topics with pregnant women were positive despite the lack of knowledge in several areas related to nutrition during pregnancy. Therefore, there is a need for continuing nutrition education for health care providers and the implementation of nutrition education programs to achieve better health outcomes.

Perception of the impact of maternal weight on pregnancy outcomes in overweight and obese women

OBJECTIVE

The purpose of this study was to assess and compare knowledge, self-awareness, and accuracy of perceived risks and weight status among overweight and obese women.

METHODS

This study was a secondary analysis of a cross-sectional questionnaire study of overweight and obese pregnant women who sought a routine first-trimester screening ultrasound. Those with a pre-pregnancy body mass index (BMI) ≥25 kg/m² (calculated using self-reported height and weight) were included. Perceived associations between estimated weight category and risk of pregnancy complications were assessed and compared in the overweight and obese groups. The perceived weight category was compared to an estimated weight category. A logistic regression identified the demographic and medical factors associated with correct identification of risk factors.

RESULTS

A total of 169 participants (88 overweight; 81 obese) were included. Most participants believed their weight did not impact the ultrasound detection of a fetal malformation (92.1% overweight vs. 55.6% obese, p < .01). Few participants associated their weight with pregnancy-related problems (6.8% overweight vs. 24.7% obese, p < .01). Most participants did not associate their weight with specific maternal complications (72.7% overweight vs. 45.7% obese, p < .01) and fetal complications (83.0% overweight vs. 71.6% obese, p = .08). More obese than overweight women underestimated their weight category (64.4% vs 41.3% overweight, p = .01). Women who correctly estimated their weight status, non-Hispanic participants, and those with a history of depression or at least one maternal co-morbidity were more likely to associate their weight with increased risk for pregnancy-related problems.

CONCLUSION

Although more obese than overweight women associated excess weight with pregnancy complications, both groups underestimated the impact on their pregnancies. Targeted educational programs are needed to improve the risk perception of these populations prior to pregnancy with the goal of improving their weight statuses and pregnancy outcomes.

Strengthening maternal nutrition counselling during routine health services: a gap analysis to guide country programmes

OBJECTIVE

The WHO recommends counselling on healthy eating, weight gain, and physical activity during antenatal care (ANC) and postnatal care (PNC), yet advice and information are often not tailored to women's nutritional needs and contexts. The purpose of the gap analysis was to identify key elements related to the provision of maternal nutrition counselling during routine health contacts and provide programme considerations to strengthen quality service delivery.

DESIGN

A search of PubMed, Cochrane Library, CINAHL Plus and Scopus databases was conducted to retrieve studies from January 2010 to December 2021. Using inclusion criteria, quantitative, qualitative and mixed methods studies were included in the final gap analysis.

SETTING

Low-, middle- and high-income country contexts.

PARTICIPANTS

Following application of gap analysis criteria, thirty-seven articles from sixteen countries were included in the analysis.

RESULTS

Gaps in delivery of maternal nutrition counselling include provider capacity building, frequency, content and delivery platforms. Globally, counselling on appropriate weight gain during pregnancy is often not delivered with the desired content nor quality, while targeted counselling to overweight and obese women was provided in several high-income country contexts. Delivery of maternal nutrition counselling through multiple delivery platforms demonstrated improvements in maternal diet and/or weight gain during pregnancy.

CONCLUSIONS

Strengthening the integration of maternal nutrition counselling into pre- and in-service curricula, routine health provider training, supportive supervision and provider mentoring is needed. Future efforts may consider generating global and regional weight gain guidelines and incorporating maternal nutrition counselling indicators as part of quality-of-care ANC/PNC standards and routine health systems.

Encouraging appropriate gestational weight gain in high-risk gravida: A randomized controlled trial

Trial Design

Excessive gestational weight gain (GWG) can increase pregnancy morbidity and is particularly problematic for women with pregestational obesity. A lifestyle modification intervention was introduced to gravida with obesity to decrease excessive GWG as compared to usual care (UC).

Methods

A randomized controlled trial was conducted to improve healthy lifestyle behaviors to manage appropriate GWG. Consenting participants with prepregnancy obesity and singletons ≤17 weeks were randomized to (1) Usual Care (UC): usual written educational materials and counseling by obstetric provider or (2) Enhanced Care (EC): UC plus (a) personalized letter from physician detailing appropriate GWG; (b) access to individualized GWG chart; (c) ongoing counseling with registered dietitian/nutritionist (RDN). The primary outcome was proportion with GWG ≤9.1 kg, as this is upper limit recommended by Institute of Medicine (IOM). Total GWG and GWG as less than/within/greater than IOM recommendations (in aggregate and stratified by obesity class), and pregnancy/neonatal outcomes were evaluated as secondary outcomes.

Results

Analyses included 105 participants in EC and 109 in UC arms. The groups had similar demographics: 46% with class I obesity, 26% class II, and 28% class III. There were no group differences for any GWG, pregnancy, or neonatal outcomes when analyzed in aggregate. As compared to those randomized to the EC arm, participants in UC arm with class I obesity gained 1.4 kg less and those with class II obesity were significantly more likely to gain within IOM guidelines (14.8% vs. 40.0%, adjusted p = 0.04). Participants with class III obesity randomized to EC arm were more likely to gain within IOM guidelines as compared to participants randomized to UC arm (29.0% vs. 6.7%, adjusted p = 0.02).

Conclusion

There were no differences in GWG observed between groups when analyzing participants in aggregate. However, a physician's letter detailing appropriate GWG, patient portal access to a personalized GWG chart, and RDN consultation were helpful for encouraging GWG within IOM guidelines for women with prepregnancy class III obesity. Women with class I or II obesity had better GWG outcomes without these additional interventions.

Qualitative inquiry with primary care providers and specialists about adult weight management care and referrals

Obesity is a highly prevalent disease and providers are expected to offer or refer patients for weight management yet increasingly fewer clinical visits address obesity. Challenges to offering care are known but less is known about referrals and how specialists who treat obesity-related comorbidities address care and referrals. This study explored perceptions of primary care providers (PCPs) and specialty providers regarding care and referrals for weight management, specifically referrals to programs in the community setting. A qualitative design was used to interview 33 PCPs (mean age 54 years) and 31 specialists (cardiology, gynecology, endocrinology, and orthopedics [mean age 62 years]) in the USA during 2019. Each interview was conducted by telephone, audio-recorded, and transcribed verbatim. Inductive analysis was used and followed the constant comparative method. Four themes emerged from the data including (a) Clinical guidelines and provider discretion influence obesity care; (b) Facilitators and barriers to discussing weight and small step strategies; (c) Informal referrals are made for weight management in community settings; and (d) Opportunities and challenges for integrating clinical and community services for weight management. Facilitating referrals to effective programs, ideally with a feedback loop could coordinate care and enhance accountability, but education, compliance, and cost issues need addressed. Care may be offered but not be well-aligned with clinical guidelines. Knowledge gaps regarding community programs' offerings and efficacy were evident. Referrals could be systematically promoted, facilitated, and tracked to advance weight management objectives.

Association Between Maternal Body Mass and Physical Activity Counseling During Pregnancy

Aims: The antenatal period provides an important opportunity for giving advice on healthy lifestyle choices. However, the prevalence of maternal obesity is increasing, and women report that they do not receive counseling. We investigated the information given to pregnant women on gestational weight gain, physical activity, and nutrition during pregnancy in relation with their initial weight status, current gestational weight gain and diagnoses of either pre-pregnancy overweight/obesity or excessive gestational weight gain. Methods: Cross-sectional survey using a questionnaire. Pregnant participants (n = 141) were recruited from a midwife center. They completed a structured questionnaire on the information they received during their pregnancy and we assessed its relationship with their weight. Results: We found that many pregnant women did not receive advice about physical activity, gestational weight gain and nutrition (37.5, 53.2, and 66.2%, respectively). Women with weight problems (pre-pregnancy overweight/obesity and excessive gestational weight gain) were less targeted for counseling, although more than 80% of the women viewed receiving information on these topics as positive. Also, being informed of a weight problem was associated with a greater chance of receiving information about physical activity, gestational weight gain and nutrition (all p < 0.05). However, verbalization of the weight problems was low (14.0% of women with pre-pregnancy overweight were informed of their status). Conclusion: Health professionals should dispense more information, especially on PA and particularly for women with weight problems. Verbalization of the weight problem seems associated with more frequent transmission of information.

A Review of the Clinician's Role in Women's Weight Management and Implications for Women's Health and Pregnancy Outcomes

Importance

Ten years have passed since the Institute of Medicine (IOM) released its recommendations for gestational weight gain (GWG), based on a woman's prepregnancy body mass index. Despite this, the majority of women do not gain the appropriate gestational weight; most women gain too much weight, and a small but substantial number gain too little.

Objective

We review the literature concerning GWG, the opinions and practices of clinicians in managing their patients' weight, and how these practices are perceived by patients. We also review several randomized control trials that investigate the efficacy of clinical intervention in managing GWG.

Evidence Acquisition

A literature review search was conducted with no limitations on the number of years searched.

Results

The number of clinicians who are aware of and use the IOM recommendations has increased, but the prevalence of inappropriate GWG has not decreased. Clinicians report feeling less than confident in their ability to have an impact on their patients' weight gain, and there are discrepancies between what clinicians and patients report regarding counseling. Many randomized control trials demonstrate a beneficial impact of clinical intervention, highlighting the importance of collaboration and technology to provide educational information and support throughout a pregnancy.

Conclusions

Pregnancy provides an opportunity for clinicians to have open and direct conversations with their patients about their weight. Providing clinicians with the tools, skillset, and confidence to assist in the management of GWG is essential to the health of women and their children, and warrants further investigation.

Midwives' and obstetricians' level of knowledge of appropriate gestational weight gain recommendations for pregnancy: A systematic review

BACKGROUND

Excessive gestational weight gain (GWG) is a modifiable risk factor associated with maternal and infant health, and pregnancy outcomes. However, several factors influence the provision of health promotion advice including professional knowledge. This review aims to summarize published evidence relating to midwives' and obstetricians' knowledge of GWG guidelines.

METHODS

Electronic database searches were carried out using EMBASE, CINAHL, PubMed, Web of Science, and Cochrane Database. English-language studies and quantitative results were included. Identified studies were screened by two authors independently. Disagreements were discussed with a third reviewer. A review protocol was submitted for registration with PROSPERO in May 2019.

RESULTS

From 10 960 records identified in preliminary searches, 12 studies reporting on 2652 midwives and obstetricians collectively were included. All studies were conducted in high-income countries. Synthesis of data was difficult as guidelines and methods for assessing knowledge varied. Midwives were mainly reported as the leading participant, with limited data available on obstetrician knowledge. Both groups demonstrated insufficient knowledge of GWG guidelines. Self-reported knowledge was significantly higher than those assessed by direct knowledge.

CONCLUSIONS

This review highlights a substantial gap in health care professionals' knowledge of GWG guideline content which needs to be addressed. Differences between professionals' direct knowledge and self-reported knowledge are important for clinical practice as it may inhibit the provision of evidence-based advice. It is important to accurately assess knowledge in this area to develop further training for midwives and obstetricians to improve health promotion during pregnancy.

Methodological quality of clinical practice guidelines for nutrition and weight gain during pregnancy: a systematic review

CONTEXT

Ensuring a healthy pregnancy and achieving optimal gestational weight gain (GWG) are important for maternal and child health. Nevertheless, the nutritional advice provided during pregnancy is often conflicting, suggesting limited adherence to clinical practice guidelines (CPGs).

OBJECTIVE

The aim of this review was to identify all CPGs on maternal nutrition and GWG and to critically appraise their methodological quality.

DATA SOURCES

The MEDLINE/PubMed, Cochrane, Guidelines International Network, and BMJ Best Practice databases, along with gray literature, were searched from inception until February 2019 for CPGs and consensus, position, and practice papers.

STUDY SELECTION

Clinical practice guidelines published in English and containing advice on maternal nutrition or GWG were eligible.

DATA EXTRACTION

Two authors independently extracted data on items pertaining to maternal nutrition or GWG, and CPGs were appraised using the AGREE II instrument.

RESULTS

Twenty-two CPGs were included. All scored adequately in the "scope" domain, but most were considered inadequate with regard to stakeholder involvement, rigor of development, applicability, and editorial independence. Many CPGs lacked patient or dietician involvement, and more than half did not disclose funding sources or conflicts of interest. Guidance on GWG was based mostly on Institute of Medicine thresholds, while nutrition recommendations appeared scattered and heterogeneous.

CONCLUSION

Despite the importance of maternal nutrition and the plethora of advising bodies publishing relevant guidance, there is room for substantial improvement in terms of development standards and content of nutritional recommendations.

Clinical characteristics and efficacy evaluation of antiviral therapy in pregnant women with chronic hepatitis B virus infection

BACKGROUND

During pregnancy, decreased maternal liver blood supply and increased load metabolism make woman susceptible to hepatitis attack. Severe cases often develop liver failure, leading to coagulation mechanism abnormality, bleeding and infection, fetal distress, premature delivery, stillbirth, etc. Therefore, high attention to the treatment and management of pregnant women with chronic hepatitis B virus (HBV) infection is the key to reducing the mother-to-child transmission of HBV, representing an important issue of concern for clinical medical personnel. Therefore, the early diagnosis and treatment of hepatitis attack during pregnancy are particularly important.

AIM

To observe the clinical characteristics of HBV in pregnant women and evaluate the efficacy of antiviral therapy.

METHODS

A total of 180 pregnant women with chronic HBV infection who visited Yuyao Maternal and Child Health Center of Zhejiang Province from February 2017 to June 2019 were selected as study subjects. Liver function was tested every 4 to 12 wk during pregnancy, and HBV serum markers were checked to determine whether there was hepatitis attack during pregnancy. For those with a definite diagnosis, tibivudine was given orally at a dose of 600 mg once per day. The clinical characteristics, alanine aminotransferase (ALT), HBV serum markers, and HBV DNA changes in pregnant women with chronic HBV infection were recorded. ALT recovery rate, HBV DNA and hepatitis B e antigen (HBeAg) negative conversion rate, and HBeAg seroconversion rate after antiviral treatment at different time points during pregnancy were also recorded.

RESULTS

Of the 180 pregnant women with chronic HBV infection included in this study, 48 (26.67%) had hepatitis attacks during pregnancy. The average age was 32.3 ± 2.4 years. The duration of hepatitis attacks ranged from 6 to 34 wk, with an average of 20.3 ± 7.8 wk. The mean value of ALT was 224.95 ± 19.6 U/L. Compared with pregnant women without hepatitis attack during pregnancy, ALT and HBV DNA changes were significant (P < 0.05), and hepatitis B surface antigen and HBeAg quantification were significantly reduced (P < 0.05). For hepatitis attacks during pregnancy, with the extension of treatment time, ALT recovery rate, HBV DNA negative conversion rate, HBeAg negative conversion rate, and HBeAg seroconversion rate had varying degrees of rise. Especially at 36 wk after treatment, the ALT recovery rate was 100.0%, HBV DNA negative conversion rate was 72.92%, HBeAg negative conversion rate was 41.67%, and HBeAg seroconversion rate was 37.5%, which were significantly higher than those at 6 wk, 12 wk, and 24 wk of treatment (P < 0.05).

CONCLUSION

Hepatitis attacks in pregnant women with chronic HBV infection usually occur in the second trimester.

Patient Attitudes toward Gestational Weight Gain and Exercise during Pregnancy

Body mass index (BMI) and gestational weight gain (GWG) are important factors for neonatal and maternal health. Exercise helps women moderate their BMI and GWG, and provides health benefits to mother and child. This survey study assessed patients' perceptions of counseling they received during pregnancy, their sources of information about GWG, and their attitudes toward exercise during pregnancy. We distributed an anonymous survey to 200 pregnant women over the age of 18 at a tertiary care center in Danville, Pennsylvania. Survey questions included demographics, discussions with medical providers regarding GWG and exercise, and their exercise habits before and during pregnancy. 182 women (91%) responded. Most reported their provider discussed weight and diet (78.8%), expected GWG (81.6%), and exercise during pregnancy (79.8%); however, 28% of obese women and 25% of women who did not plan to exercise during pregnancy reported not receiving exercise counseling. Approximately 20% of women did not plan to exercise during pregnancy. Women decreased the number of days per week they exercised (40.6% with 3 or more days prepregnancy versus 30.7% during pregnancy, P = 0.002). Some patients who did not exercise prior to pregnancy (12%) expressed interest in a personal training session. Among women in the eight month or later, 42.4% were above GWG recommendations. Our study found barriers to adequate activity during pregnancy; 20% of pregnant women not receiving/remembering counseling regarding exercise. Interest in personal training from patients that did not exercise suggests they would benefit from increased efforts to encourage physical activity. Exercise and GWG counseling based in medical science as well as patient psychological needs will help efforts to reduce GWG and improve pregnancy outcomes.

Associations Between Maternal Body Mass Index, Gestational Weight Gain, Maternal Complications, and Birth Outcome in Singleton, Term Births in a Largely Non-Hispanic White, Rural Population

Background: In 2009, the Institute of Medicine (IOM) published guidance on gestational weight gain (GWG) modified by body mass index (BMI). GWG outside of IOM recommendations negatively affects birth outcomes and child health. This study examined the relationship between BMI, GWG, birth complications, and birth outcomes in a rural, non-Hispanic white population over 10 years. Materials and Methods: We examined maternal BMI, GWG, birth weight, birth complications, and Apgar score in 18,217 term singleton births from medical records at Geisinger, PA from 2006 to 2015. Primary outcomes were GWG, delivery mode, Apgar score, and infant birth weight. Results: A majority of women (74.2%) had GWG outside of recommendations. Prevalence of cesarean delivery was highest for women with GWG above recommendations regardless of BMI. One in five neonates of obese women with GWG above recommendations had Apgar scores below eight. Although most births were normal for gestational age (88%), underweight women who gained below recommendations had the highest percentage of small for gestational age (SGA) births (10.4%) and obese women who gained above recommendations had the highest percentage of large for gestational age (LGA) births (22.2%). Among women with BMIs above 35 kg/m² and GWG within recommendations, 18.9% of births were LGA. Conclusions: Most pregnant women are not gaining weight within recommendations. GWG outside of IOM recommendations resulted in poorer birth outcomes, particularly in underweight and obese women. Underweight women with GWG below recommendations are at increased risk for SGA neonates. We suggest reducing GWG recommendations for women above 35 kg/m² to decrease LGA births and pregnancy complications.

Gestational weight gain counselling gaps as perceived by pregnant women and new mothers: Findings from the electronic maternal health survey

PROBLEM

Too much or too little gestational weight gain (GWG) can negatively impact maternal and fetal health, according to Institute of Medicine Guidelines.

BACKGROUND

Health care providers are key players in providing reliable evidence-informed prenatal advice related to appropriate GWG. However, there appears to be inconsistent GWG communication among healthcare providers during prenatal care.

AIM

To determine pregnant women and new mothers' perceptions of healthcare provider GWG and dietary counselling during the pregnancy period.

METHODS

A reliable and validated cross-sectional electronic survey was administered to currently pregnant women and women who had recently given birth. The web-based questionnaire was self-administered and took 10-25min.

FINDINGS

A total of 1507 eligible women participated in the survey. More than half (57%) reported that their healthcare provider talked to them about personal weight gain limits. Of these participants, about a third (34%) of participants were counselled regularly at each or most visits. Among the women that were not counselled on personal GWG limits, over half (56%) reported that healthcare provider guidance would have been helpful to achieve their target weight. Less than half (45%) of participants reported that their healthcare providers discussed dietary requirements or changes in pregnancy.

DISCUSSION

These findings highlight areas for improvement in prenatal dialogue, which can support better outcomes for both mother and baby.

CONCLUSION

A better understanding of pregnant and mothers' perceptions about weight and diet counselling is needed to understand what may need greater attention and clarification and to improve such dialogue.

Targeting obstetric providers in interventions for obesity and gestational weight gain: A systematic review

Background

Providers need to be comfortable addressing obesity and gestational weight gain so they may give appropriate care; however, health care providers lack guidelines for the most effective educational strategies to assist in providing optimal care.

Objective

To identify studies that involved the obstetric provider in interventions for either the perinatal management of obesity and/or gestational weight gain in a systematic review.

Search strategy

A keyword search of databases was performed up to April 2017.

Selection criteria

Obstetric providers who participated in an intervention with the aim to change a provider’s clinical practice, knowledge, and/or satisfaction with the intervention in relation to the perinatal management of obesity or gestational weight gain were included. Provider intervention could include training or education, changes in systems or organization of care, or resources to support practice. PROSPERO database #42016038921.

Data collection and analysis

Bias was assessed according to the validated Mixed Methods Appraisal Tool. The following variables were synthesized: study location and setting, provider and patient characteristics, intervention features, outcomes and efficacy, and strengths and weakness.

Main results

Of the 6,821 abstracts screened, seven studies (4 quantitative, 3 mixed-methods) with a total of 335 providers met the inclusion criteria; two of which focused on the management of obesity, three focused on gestational weight gain, and two focused on both topics. Interventions that incorporated motivational interviewing skills (n = 2), required additional training for the research study and addressed specific knowledge deficits such as nutrition and exercise (n = 3), and interfaced with the electronic medical record (n = 1) demonstrated the greatest impact on provider outcomes. Provider reported satisfaction scores were generally favorable, but none addressed provider-level efficacy in practice change.

Conclusions

Given the limited number of studies, varying range of provider participation, and lack of provider-level efficacy, further evaluation of provider training and involvement in interventions for perinatal obesity or gestational weight gain is indicated to determine best practices for provider and patient outcomes.

A retrospective study of gestational weight gain in relation to the Institute of Medicine's recommendations by maternal body mass index in rural Pennsylvania from 2006 to 2015

Background

In 2009, the Institute of Medicine (IOM) published guidance on gestational weight gain (GWG) modified by maternal pre-pregnancy body mass index (BMI). Estimates indicate that less than half of US pregnant women have GWG within recommendations. This study examined GWG from before (2006–2009) and after (2010–2015) the release of the IOM guidance in a rural, non-Hispanic white population to assess the proportion of women with GWG outside of IOM guidance, whether GWG became more likely to be within IOM guidance after 2010, and identify potential maternal factors associated with GWG outside of recommendations.

Methods

We examined GWG in 18,217 term singleton births between 2006 and 2015 in which maternal pre-pregnancy BMI could be calculated from electronic medical records at Geisinger, PA, and a subset of 12,912 births in which weekly GWG in the third trimester could be calculated. The primary outcome was whether GWG was below, within, or above recommendations based on maternal BMI. The relationships between GWG, maternal BMI, parity, age at conception, gestation length, and maternal blood pressure were examined.

Results

GWG declined with increasing maternal BMI, however, more than 50% of overweight and obese women gained above IOM recommendations. About one of five women gained below recommendations (21.3%) with underweight women the most likely to gain below recommendations (33.0%). The proportion of births with usable data increased after 2010, driven by a higher probability of recording maternal weight. However, the proportion of women who gained below, within or above recommendations did not change over the ten years. GWG above recommendations was associated with higher maternal BMI, lower parity, and longer gestation. GWG below recommendations was associated with lower maternal BMI, higher parity, shorter gestation, and younger age at conception. Maternal blood pressure was higher for GWG outside recommendations.

Conclusions

Despite the publication of IOM recommendations in 2009 and an apparent increase in tracking maternal weight after 2010, GWG in this population did not change between 2006 and 2015. A majority of overweight and obese women gained above recommendations. GWG below recommendations continues to occur, and is prevalent among underweight women.

Prevention of obesity and diabetes in pregnancy: is it an impossible dream?

The obesity and diabetes epidemic is an unintended consequence of economic, social, and technological changes. In nonpregnancy, people identified as high risk to develop type 2 diabetes may delay progression by 30-70% with lifestyle interventions and pharmacological agents. In pregnancy, lifestyle interventions have been the primary focus to prevent fetal short- and long-term complications that may evolve into substantial weight gain and gestational diabetes mellitus. The dilemma for obstetricians is whether diabetes and obesity can be prevented and not simply treated after the fact. Interventions after women become pregnant may be too late to see the kinds of meaningful improvements in child and maternal health because there is a short interval from gestational diabetes mellitus diagnosis to delivery. Therefore, future efforts need to incorporate quality research, lifestyle interventions that designate time of initiation and duration during pregnancy, the preventative intervention of a prepregnant "fourth trimester," coupled with the concept of precision medicine so that there is the potential to make the impossible dream a reality.

Achieving Appropriate Gestational Weight Gain: The Role of Healthcare Provider Advice

BACKGROUND

The Institute of Medicine (IOM) revised gestational weight gain recommendations in 2009. We examined associations between healthcare provider advice about gestational weight gain and inadequate or excessive weight gain, stratified by prepregnancy body mass index category.

MATERIALS AND METHODS

We analyzed cross-sectional data from women delivering full-term (37-42 weeks of gestation), singleton infants from four states that participated in the 2010-2011 Pregnancy Risk Assessment Monitoring System (unweighted n = 7125). Women reported the weight gain range (start and end values) advised by their healthcare provider; advice was categorized as follows: starting below recommendations, starting and ending within recommendations (IOM consistent), ending above recommendations, not remembered, or not received. We examined associations between healthcare provider advice and inadequate or excessive, compared with appropriate, gestational weight gain using adjusted prevalence ratios (aPR) and 95% confidence intervals (CIs).

RESULTS

Overall, 26.3% of women reported receiving IOM-consistent healthcare provider advice; 26.0% received no advice. Compared with IOM-consistent advice, advice below recommendations was associated with higher likelihood of inadequate weight gain among underweight (aPR 2.22, CI 1.29-3.82) and normal weight women (aPR 1.57, CI 1.23-2.02); advice above recommendations was associated with higher likelihood of excessive weight gain among all but underweight women (aPR range 1.36, CI 1.08-1.72 to aPR 1.42, CI 1.19-1.71). Not remembering or not receiving advice was associated with both inadequate and excessive weight gain.

CONCLUSIONS

Few women reported receiving IOM-consistent advice; not receiving IOM-consistent advice put women at-risk for weight gain outside recommendations. Strategies that raise awareness of IOM recommendations and address barriers to providing advice are needed.
