Managing Gestational Weight Gain: Obstetricians' Perceived Barriers and Interventions

The Effect of Obesity and Pregnancy Weight Gain on Maternal and Child Health

In this study, we estimate the effect of prepregnancy obesity and excessive pregnancy weight gain on infant and maternal health outcomes. We rely on a large sample of maternally linked restricted data from 2004 to 2019 South Carolina birth certificates, which allow us to track the same mothers during multiple pregnancies over a period of more than 15 years. To address possible limitations of previous research, we account for genetic confounders and unobservable maternal and environmental factors by relying on a maternal fixed effects strategy. We find that gaining above recommended amounts of weight increases the likelihood of delivering a high weight infant by 2.34 percentage points, while being obese increases this likelihood by 2.58 percentage points. These large negative effects of weight gain outside recommended ranges, as well as the effects of being obese, are present in White and Black mothers. Also, our results indicate that mothers who gained too much weight, or were obese, had a higher likelihood of cesarean section and higher likelihood of being induced. Finally, among the subsample of Medicaid mothers, excessive pregnancy weight gain as well as inadequate weight gain increased the likelihood of NICU admission.

Barriers and enablers to addressing smoking, nutrition, alcohol consumption, physical activity and gestational weight gain (SNAP-W) as part of antenatal care: A mixed methods systematic review

BACKGROUND

International clinical guidelines recommend that smoking, nutrition, alcohol consumption, physical activity and gestational weight gain (SNAP-W) be addressed as part of routine antenatal care throughout pregnancy. However, guideline recommendations are poorly implemented, and few antenatal care recipients routinely receive the recommended care. There is a need to establish the determinants (barriers and enablers) to care delivery to inform strategies to improve implementation. This systematic review aimed to synthesize qualitative and quantitative evidence of the barriers and enablers to the routine delivery of antenatal care targeting SNAP-W health risks.

METHODS

A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Seven databases were searched for relevant studies published between January 2001 and November 2023. Study findings were coded and analysed according to the domains of the Theoretical Domains Framework (TDF).

RESULTS

Forty-nine studies were included in the review, 27 qualitative studies and 22 quantitative studies. The studies were conducted in 14 countries. Data were collected from 7146 antenatal care providers (midwives, Aboriginal health workers, obstetricians, medical officers, general practitioners) and 352 barriers and enablers were identified. Across all SNAP-W health risk and antenatal care provider groups, the predominant TDF domain was 'environmental context and resources', identified in 96% of studies. Barriers within this domain included insufficient time, limited access to and quality of resources, and limited organisational supports. 'Beliefs about consequences' was the second most common TDF domain, reported in 67% of studies, particularly studies of care related to alcohol use, nutrition/ physical activity/ gestational weight gain and those involving midwives, multidisciplinary practitioners and general practitioners. 'Optimism' was the second most common TDF domain for studies of smoking-related care and involving obstetricians, gynaecologists, and other mixed medical professions.

CONCLUSIONS

It is critical that determinants related to environmental context and resources including time, resources and organisational supports are considered in the development of strategies to support the implementation of recommended antenatal care related to SNAP-W risks. Strategies addressing clinician beliefs about consequences and optimism may also be needed to support the implementation of care related to specific health behaviours and by specific antenatal care provider groups.

A new care pathway to optimize gestational weight gain in twin pregnancies

BACKGROUND

Maternal gestational weight gain is an important determinant of pregnancy outcomes and may have an even greater role in twin pregnancies because of their higher rate of pregnancy complications and greater nutritional demands. However, data on the optimal week-specific gestational weight gain in twin pregnancies and on interventions that should be applied in cases of inadequate gestational weight gain are limited.

OBJECTIVE

This study aimed to determine whether a new care pathway that involves monitoring gestational weight gain using a week-specific chart, along with a standardized protocol for managing cases with inadequate gestational weight gain, can optimize maternal gestational weight gain in twin pregnancies.

METHODS

In this study, patients with twin pregnancies followed in a single tertiary center between February 2021 and May 2022 were exposed to the new care pathway (postintervention group). Gestational weight gain and clinical outcomes were compared with those of a previously described cohort of patients with twins followed in our clinic before the implementation of the new care pathway (preintervention group). The new care pathway targeted patients and care providers and included educational material, a newly developed body mass index group-specific gestational weight gain chart, and a stepwise management algorithm in cases of inadequate gestational weight gain. The body mass index group-specific gestational weight gain charts were divided into 3 zones: (1) green zone (optimal gestational weight gain at 25th-75th centiles); (2) yellow zone (suboptimal gestational weight gain at 5th-24th or 76th-95th centiles); and (3) gray zone (abnormal gestational weight gain, at <5th or >95th centile). The primary outcome was the overall proportion of patients achieving optimal gestational weight gain at birth.

RESULTS

A total of 123 patients were exposed to the new care pathway and were compared with 1079 patients from the preintervention period. Patients in the postintervention group were more likely to achieve optimal gestational weight gain at birth (60.2% vs 47.7%; adjusted odds ratio, 1.91; 95% confidence interval, 1.28-2.86) and were less likely to achieve low-suboptimal gestational weight gain (7.3% vs 14.7%; adjusted odds ratio, 0.41; 95% confidence interval, 0.20-0.85) or any suboptimal gestational weight gain (26.8% vs 34.8%; adjusted odds ratio, 0.60; 95% confidence interval, 0.39-0.93) at birth. In addition, patients in the postintervention group were less likely to have low-abnormal gestational weight gain anytime during gestation (18.9% vs 29.1%; P=.017) and were more likely to have normal gestational weight gain throughout pregnancy (21.3% vs 14.0%; P=.031) or high-abnormal gestational weight gain anytime during gestation (18.0% vs 11.1%; P=.025), suggesting that in comparison with standard care, the new care pathway is more effective in preventing patients from moving into the low-abnormal zone than the high-abnormal zone. Furthermore, the new care pathway was more effective than standard care in correcting high-suboptimal gestational weight gain and high-abnormal gestational weight gain.

CONCLUSION

Our findings suggest that the new care pathway may be effective in optimizing maternal gestational weight gain in twin gestations, which may in turn contribute to better clinical outcomes. This is a simple, low-cost intervention that can be easily disseminated among providers caring for patients with twin pregnancies.

The short-term effect of a mHealth intervention on gestational weight gain and health behaviors: The SmartMoms Canada pilot study

Gestational weight gain (GWG) has been shown to impact several maternal-infant outcomes. Since healthcare provider guidance on weight gain and healthy behaviors alone has failed to help women to meet guidelines during pregnancy, a practical adjunctive approach is to deliver evidence-based behavior change programs through mobile interventions. The present study aimed to assess the short-term effect of the SmartMoms Canada app to promote adequate GWG and healthy behaviors. Twenty-nine pregnant women were recruited in this app-based intervention trial to test whether a higher app usage (≥ 3.8 min·week^-1) between 12-20 gestational weeks and 24-28 gestational weeks improved GWG, diet, physical activity, and sleep, compared to women with a lower app usage (< 3.8 min·week^-1). Two-way mixed ANOVA for repeated measures was used to estimate the effect of the app usage and time, as well as their interaction on GWG and healthy behaviors. The likelihood ratio was used to examine the association between app usage categorization and GWG classification. Cramer's V statistic was used to estimate the effect size for interpretation of the association. Pregnant women using the SmartMoms Canada app more frequently had a higher moderate-to-vigorous physical activity (MVPA) daily average when compared with women with a lower usage (mean difference: 17.84 min/day, 95% CI: 2.44; 33.25). A moderate effect size (28.6% vs. 15.4%; Cramer's V = 0.212) was found for the association between app categorization and rate of GWG, representing a greater adherence to the GWG guidelines in women in the higher app usage group vs. the lower app usage group. Considering other physical activity, diet, and sleep variables, no app categorization effect was observed. A short-term higher usage of SmartMoms Canada app has a positive effect on objectively-measured MVPA.

How Do Health Schemas Inform Healthy Behaviours During Pregnancy? Qualitative Findings from the Be Healthy in Pregnancy (BHIP) Study

OBJECTIVE

Excess gestational weight gain (GWG) is associated with adverse long and short-term outcomes for both woman and child, yet evidence demonstrates pregnant women are frequently not engaging in healthy behaviours linked to appropriate weight gain. The purpose of the current study was to explore women's values and beliefs related to weight, nutrition and physical activity during pregnancy and to describe how these beliefs influence their behaviours.

METHODS

As part of a larger randomized controlled trial, we conducted 20 focus groups with 66 pregnant women between 16 and 24-weeks gestation using a semi-structured interview guide. Focus groups were recorded and transcribed verbatim and analyzed using a grounded theory approach.

RESULTS

Three personal health schemas emerged from the findings which illustrated women's diverging beliefs about their health behaviours in pregnancy. 'Interconnected health' described beliefs regarding the impact their health had on that of their growing baby and awareness of risks associated with inappropriate weight gain. 'Gestational weight gain as an indicator of health' illustrated perceptions regarding how GWG impacted health and the utility of guidelines. Finally, 'Control in pregnancy' described the sense of agency over one's body and health.

CONCLUSIONS FOR PRACTICE

Our results showed that health-related behaviours in pregnancy are driven by personal health schemas which are often discordant with clinical evidence. Interventions and health care provider advice aimed at behaviour modification would benefit from first understanding and addressing these schemas. Tackling the conflict between beliefs and behaviour may improve health outcomes associated with appropriate weight gain in pregnancy.

Helping Individuals Achieve a Healthy Weight Gain During Pregnancy: A Multipronged Approach

Approximately half of pregnant individuals in the United States exceed recommendations for gestational weight gain (GWG). Excessive GWG is associated with negative outcomes for maternal and infant health. In this article, we provide guidance to nurses who counsel patients about GWG. Because of negative bias toward persons with obesity, nurses need to understand their own attitudes toward obesity to provide supportive GWG counseling. The use of words such as weight is preferred to obese, and recommended GWG goals should be consistent with established guidelines. The setting of specific, measurable, attainable, realistic, and trackable behavioral goals can help translate a goal for GWG into practical actions in daily living. Mobile phone apps, if carefully chosen, may help individuals learn about and track GWG.

Midwives' and obstetricians' perspectives about pregnancy related weight management in Ethiopia: A qualitative study

BACKGROUND

Midwives and obstetricians are key maternity care providers; they are the most trusted source of information regarding nutrition and gestational weight gain. However, their views, practices and perceived barriers to managing pregnancy related weight gain have not been studied in Ethiopia. The aim of this study was to explore midwives' and obstetricians' observations and perspectives about gestational weight gain and postpartum weight management in Ethiopia.

METHODS

We conducted face-to-face interviews with 11 midwives and 10 obstetricians, from January 2019 to March 2019. All interview data were transcribed verbatim. We analysed the data using thematic analysis with an inductive approach.

RESULTS

We identified three themes and associated subthemes. Midwives and obstetricians had limited knowledge of the optimal gestational weight gain. Almost all participants were unaware of the presence of the Institute of Medicine recommendations for optimal weight gain in pregnancy. According to the study participants, women in Ethiopia do not want to gain weight during pregnancy, but do want to gain weight after the birth. Counselling about gestational weight gain and postpartum weight management was not routinely provided for pregnant women. This is mostly because gestational weight gain counselling was not considered to be a priority by maternity care providers in Ethiopia.

CONCLUSIONS

The limited knowledge of and low attention to pregnancy related weight management by midwives and obstetricians in this setting needs appropriate intervention. Adapting a guideline for pregnancy weight management and integrating it into antenatal care is essential.
