Pregnant Women with Obesity Have Unique Perceptions About Gestational Weight Gain, Exercise, and Support for Behavior Change

Factors Influencing Weight Management in Pregnant Women with Overweight or Obesity: A Meta-Synthesis of Qualitative Studies

BACKGROUND

Overweight and obesity have multiple negative consequences for the health of both the mother and the child. Interventions to prevent excessive weight gain during pregnancy have had varying success, and the proportion of pregnant women who exceed national guidelines for weight gain continues to increase.

OBJECTIVE

To investigate the influence of factors on weight management among pregnant women with overweight or obesity.

METHODS

This meta-synthesis of qualitative studies involved searching databases PubMed, Embase, Cochrane, Scopus, and Web of Science. The databases were searched on October 4, 2022, and the search was updated on April 21, 2023. The screening of titles, abstracts, and full texts was conducted utilizing Covidence software. The quality assessment of the articles was performed using the Critical Appraisal Skills Programme checklist. The Enhancing Transparency in Reporting the Synthesis of Qualitative Research statement was used to enhance transparency in reporting. A meta-aggregation approach was used to guide the data extraction and synthesis.

RESULTS

A total of 46 studies with appropriate Critical Appraisal Skills Programme scores were included for qualitative synthesis. Findings were extracted and integrated into 4 themes: psychological factors (personally driven negative emotions and society-driven negative emotions), social factors (societal attitudes and beliefs and social support resources), factors related to education and counseling (information provision and communication), and factors associated with effective care (provided care components and the method of providing effective care).

CONCLUSIONS

To improve weight management during pregnancy, health care providers should provide tailored and individualized recommendations that take into consideration the factors influencing these women.

Drivers and facilitators of weight stigma among preconception, pregnant, and postpartum women: A systematic review

Women in the preconception, pregnant, or postpartum period are susceptible to weight stigma, particularly due to the risk of excess weight gain during the reproductive life period and the negative effects of stigma on the health of both the mother and the child. Identifying the drivers and facilitators of weight stigma will help guide focused weight stigma prevention interventions. This systematic review aimed to identify the drivers and facilitators of weight stigma among preconception, pregnant, and postpartum women. In May 2022, Medline, Embase, PsycINFO, and the Maternity and Infant Care Database were searched for peer-reviewed articles published since 2010 using search terms weight AND stigma AND preconception, OR pregnant, OR postpartum. Of the 1724 articles identified, 34 fulfilled the inclusion criteria and were included in a narrative synthesis. Women reported facing insensitive language, misconceptions about obesity across all settings, and inappropriate media representation. The unavailability of appropriate equipment at facilities was reported by both women and health professionals. Our findings indicate that a rigorous effort by all stakeholders is necessary to promote regulatory, legal, and educational initiatives designed to reduce weight stigma and discrimination against women in the reproductive period.

SWIPE: a conceptual, multi-perspective model for understanding and informing interventions for weight stigma in preconception, pregnancy, and postpartum

Weight stigma is salient across the preconception, pregnancy, and postpartum (PPP) periods because of prevailing prescriptive norms and expectations about weight and weight gain during the reproductive period. Weight stigma is associated with negative physical and psychological health outcomes for mother and child. A clearly defined, multi-level conceptual model for interventions, research, and policy is critical to mitigating the adverse effects of weight stigma in PPP populations. Conceptual models of weight stigma towards PPP women have advanced our understanding of this issue and guided evidence accumulation but there remains a gap in informing the translation of evidence into action. Guided by evidence-based paradigms for conceptual model development, this paper has two primary objectives. First, we review and summarise theories, frameworks, and models from the PPP population and general literature to inform our understanding of the development and perpetuation of weight stigma for PPP women. Second, we propose a novel comprehensive intervention-guiding conceptual model that draws from and synthesises across multiple disciplines - the SWIPE (Stigma of Weight In the PPP Experience) model. This conceptual model will help to plan coordinated, multi-layered, and effective strategies to reduce and ultimately eliminate weight stigma for PPP women.

Physical activity counseling received throughout pregnancy and effect on behaviors: a quasi-experimental study

OBJECTIVE

The objective was to examine the frequency of physical activity counseling for pregnant women over the course of their pregnancies and the effect on the women's physical activity behaviors.

METHODS

A quasi-experimental study was conducted in the Maternity Unit of a hospital. Seventy-two pregnant women were randomized into a control or intervention group. Counseling about physical activity was dispensed to the women in the intervention group throughout pregnancy by health professionals who had been sensitized to its importance and the recommendations. The women in the control group received the usual consultation content. The physical activity behavior of the pregnant women in the intervention group who reported receiving physical activity counseling was evaluated. The counseling and physical activity levels were evaluated by Chi2 tests and repeated measures ANOVAs, respectively.

RESULTS

Overall, the women received little counseling in accordance with the recommendations, although the intervention group women received this counseling more frequently (p=0.049). All women in the intervention group who reported received counseling throughout pregnancy limited their decline in physical activity compared to those in the control group. The decline in total physical activity among normal-weight and overweight pregnant women was reduced in the intervention group (respectively, p=0.043 and p=0.044).

CONCLUSION

Our intervention showed the effectiveness of counseling on physical activity behaviors, although the effect was observed at the end of pregnancy. Training and sensitizing for professionals should be strengthened to ensure that counseling in line with the recommendations to maintain or increase physical activity levels throughout pregnancy is provided.

Empirical validation of the information-motivation-behavioral skills model of gestational weight management behavior: a framework for intervention

BACKGROUND

Unhealthy gestational weight gain is a modifiable risk factor for adverse maternal and child health. Appropriate and effective intervention strategies that focus on behavioral change or maintenance are critical in weight management during pregnancy. Our aim was to uncover the influencing factors and psychosocial mechanisms of gestational weight control behavior, and to construct a behavioral model suitable for intervention based on Information-Motivation-Behavioral skills (IMB) model.

METHODS

A sample of 559 pregnant women from a municipal maternal and child healthcare facility in Jiangsu Province, China was enrolled in this cross-sectional empirical study. Partial least square structural equation modelling was used to verify the hypothesized model, and post hoc analyses was used to test the effect of parity and pre-pregnancy BMI on the model.

RESULTS

The IMB model elements can predict gestational weight management (GWM) behavior well, with information being the most influential factor. As predicted, information affects GWM directly (β = 0.325, p < 0.05) and indirectly (β = 0.054, p < 0.05) through behavioral skills. Likewise, motivation has direct (β = 0.461, p < 0.05) effects on GWM, and has indirect (β = 0.071, p < 0.05) effects through behavioral skills. Behavioral skills have a direct impact (β = 0.154, p < 0.05). The model had a goodness of fit (GOF = 0.421) and was robust when tested in subgroups of different parity or pre-pregnancy BMI.

CONCLUSION

Findings from this study supported the predictions of the IMB model for GWM behavior, and identified its modifiable determinants. The tested behavior model for GWM can serve as a new validated intervention strategy in weight management among pregnant women.

Effectiveness of a nurse-led mHealth app to prevent excessive gestational weight gain among overweight and obese women: A randomized controlled trial

OBJECTIVE

To explore the effectiveness of a nurse-led mobile health (mHealth) intervention to prevent excessive gestational weight gain (GWG) in overweight and obese women.

METHODS

A randomized controlled trial with an experimental study design. Ninety-two pregnant women with body mass index (BMI) ≥25 kg/m² at less than 17 weeks gestation were recruited from two prenatal clinics in northern Taiwan from January to June 2020. The experimental group used the MyHealthyWeight (MHW) app and a wearable activity tracker (WAT), and the controls received standard antenatal treatments with no mHealth-based elements. Two hospital follow-up visits were scheduled at 24-26 weeks in the second trimester and 34-36 weeks in the third trimester. A generalized estimating equation (GEE) was used to examine the trajectories and the effectiveness of mHealth on GWG.

RESULTS

No difference in GWG was found between the intervention and control groups at baseline (p > 0.05). The GWG trajectory in the entire cohort of women with obesity exhibited a quadratic pattern (ß = 1.8, 95% confidence interval [CI] = 1.27-2.32), and intervention participants' weekly GWG was gained significantly lower than their controls in the second trimester (p < 0.05). Throughout the pregnancy, the mHealth intervention group had a significantly lower proportion of individuals who exceeded their GWG in both total (21.6% vs. 32.6%) and weekly weight gain (first trimester = 58.7% vs. 65.2%; second trimester = 45% vs. 67.4%; third trimester = 48.6% vs. 55.1%). In particular, among obese women in the third trimester, those in the intervention group gained less gestational weight than their controls. The adjusted body weight difference was 5.44 kg (p = 0.023), signifying the total GWG difference (3.30 vs. 8.74 kg) between the means of the two groups. The GEE model indicated that obese women who were aged 35 years, had prepregnancy exercise habits, perceived self-efficacy of diet, and more physical activity tended to have low GWG (p < 0.05).

CONCLUSIONS

The nurse-led mHealth-based intervention shows promising results in significantly preventing excessive GWG among high-BMI women. More effectiveness was found among the obese subgroup.

CLINICAL RELEVANCE

The mHealth-based intervention would be successfully implemented by nurses to help high-BMI women maintain their optimal body weight and promote healthy behavioral changes, particularly in diet and physical activity during pregnancy.

"Help me fight my constant battle": A focus group study of overweight and obese women's mHealth app experiences to manage gestational weight gain

OBJECTIVES

To understand and describe overweight and obese pregnant women's mHealth app experiences in managing gestational weight gain (GWG) for optimal weight goals.

DESIGN

A focus group study.

SETTING

We identified and invited pregnant women from a prenatal outpatient clinic in a metropolitan city in Northern Taiwan.

PARTICIPANTS

The participants were women whose pre-pregnancy BMI≥25 Kg/m² at antenatal booking, and have experience using smartphone apps for pregnancy e-information. A total of 13 overweight and obese women were agreed to participate, their gestation weeks from 11 to 38 weeks.

METHODS

Three focus group of six sessions were conducted from July to October of 2019. Thematic analysis was employed to inductively analyze the qualitative data.

FINDINGS

Overweight and obese pregnant women...s major concern was to safely deliver a healthy baby. Main themes identified included: planning to know more and wanting to do right, feeling like a failure and having low self-expectations, struggling with life and desiring peace of mind, yearning to be supported and hoping to be seen, adjusting for the future and embracing new technology to engage in GWG management.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

The core theme was presented as high BMI pregnant women...s shared need to be well-equipped to fight their constant weight battle, reflecting these women...s mixed feelings and barriers toward GWG control and body image during pregnancy. Experiences with a GWG addressing mHealth APP seemed to be positive and further facilitated healthy eating and physical activities, participants... self-efficacy may be increased along with satisfactory APP adherence to prevent excessive GWG for women with obesity.

Facilitators and barriers influencing weight management behaviours during pregnancy: a meta-synthesis of qualitative research

BACKGROUND

Obesity and overweight are considered risk factors for a range of adverse outcomes, including stillbirth. This study aims to identify factors reported by women influencing weight management behaviours during pregnancy.

METHODS

A systematic search was conducted in five databases from inception to 2019 and updated in 2021. Qualitative studies involving pregnant or post-partum women, from high-income countries, examining women's experiences of weight management during pregnancy were included. Meta-ethnography was used to facilitate the meta-synthesis of 17 studies.

RESULTS

Three themes were identified during the analysis: (1) Awareness and beliefs about weight gain and weight management, which included level of awareness and knowledge about dietary and exercise recommendations, risk perception and decision balance, perceived control over health and weight gain and personal insecurities. (2) Antenatal healthcare, women's experiences of their interactions with healthcare professionals during the antenatal period and the quality of the education received had an effect on women's behaviour. Further, our findings highlight the need for clear and direct information, and improved interactions with healthcare professionals, to better support women's weight management behaviours. (3) Social and environmental influence, the social judgement and stigmatization associated with overweight and obesity also acted as a negative influence in womens' engagement in weight management behaviours.

CONCLUSION

Interventions developed to promote and maintain weight management behaviours during pregnancy should consider all levels of influence over women's behaviours, including women's level of awareness and beliefs, experiences in antenatal care, education provision and social influence.

Neighborhood walkability and poverty predict excessive gestational weight gain: A cross-sectional study in New York City

OBJECTIVE

This study evaluated associations between neighborhood-level characteristics and gestational weight gain (GWG) in a population-level study of 2015 New York City births.

METHODS

Generalized linear mixed-effects models were used to estimate odds ratios (ORs) for associations between neighborhood-level characteristics (poverty, food environment, walkability) within 1 km of a residential Census block centroid and excessive or inadequate GWG compared with recommended GWG. All models were adjusted for individual-level sociodemographic characteristics.

RESULTS

Among the sample of 106,285 births, 41.8% had excessive GWG, and 26.3% had inadequate GWG. Residence in the highest versus lowest quartile of neighborhood poverty was associated with greater odds of excessive GWG (OR: 1.17, 95% CI: 1.08-1.26). Residence in neighborhoods in the quartile of highest walkability compared with the quartile of lowest walkability was associated with lower odds of excessive GWG (OR: 0.87, 95% CI: 0.81-0.93). Adjustment for prepregnancy BMI attenuated the associations for neighborhood poverty, but not for walkability. Neighborhood variables were not associated with inadequate GWG.

CONCLUSIONS

These analyses indicate that greater neighborhood walkability is associated with lower odds of excessive GWG, potentially from differences in pedestrian activity during pregnancy. This research provides further evidence for using urban design to support healthy weight status during pregnancy.

Exploration of Diet Quality by Obesity Severity in Association with Gestational Weight Gain and Distal Gut Microbiota in Pregnant African American Women: Opportunities for Intervention

OBJECTIVE

To conduct an exploratory examination of dietary patterns and quality during pregnancy in African-American women who were class I, II, or III obese, and those women with normal pre-pregnancy body mass index (pBMI), as well to identify dietary factors associated with GWG, and changes in the distal gut microbiome. African American women represent the largest group affected by pre-pregnancy obesity, a risk factor for several adverse birth outcomes.

METHODS

This prospective study investigated the association between diet, distal gut microbiome, and GWG among African-American women (n = 21) with obesity (n = 15) compared to women with a normal pre-pregnancy body mass index (pBMI) (n = 6) at two time points, 27-29 and 37-39 weeks gestation. Dietary patterns associated with obesity severity and GWG gain were assessed using Welch's T-test and Mann-Whitney U. The association between the gut microbiome and dietary patterns was assessed using a regression-based kernel association test and the adaptive microbiome-based sum of powered score test.

RESULTS

In early pregnancy, dietary intake of Total Fruits and Greens and Beans was significantly different between pBMI and GWG groups; significance was 0.022 and 0.028 respectively. Women with Class II/III obesity and those with GWG above guidelines had Healthy Eating Index (HEI) scores below 50, meeting less than 75% of dietary guidelines, and did not meet recommendations for fruit and vegetable or fiber intake. We found no significant associations between the microbiome composition and diet (HEI Scores).

CONCLUSIONS FOR PRACTICE

Overall, the results indicate that women with pBMI obesity are not meeting minimum dietary guidelines for nutrient intakes during pregnancy, specifically fruits, vegetables, and fiber, regardless of GWG. Interventions for African-American women with pre-pregnancy obesity, with a focus on increasing consumption of fruits and vegetables, would be beneficial to control GWG and improve birth outcomes.

Exercise and the Prevention of Gestational Diabetes Mellitus

Gestational diabetes mellitus (GDM) is associated with pregnancy complications and fetal complications, as well as long-term health consequences for women and their offspring. Pregnancy is a pseudodiabetogenic state of increasing insulin resistance and decreasing insulin sensitivity, which places a woman at increased risk for GDM. Exercise facilitates the uptake of blood glucose into cells to be used for energy, making exercise a potential strategy in preventing GDM. Extensive evidence has found an association between consistent moderate to vigorous exercise in pregnancy and the prevention of GDM. With close attention to risk factors, maternity care nurses and other health care providers can play an important role in educating pregnant women on exercise recommendations to help them achieve optimal health and wellness.

Weight Stigma across the Preconception, Pregnancy, and Postpartum Periods: A Narrative Review and Conceptual Model

Weight stigma is a pervasive issue promoting significant adverse health and psychosocial consequences. Preconception, pregnant, and postpartum women are particularly vulnerable to weight stigma, which can directly impact their health and that of the next generation. Of note, weight stigma affects women living with obesity who are already at risk for developing gestational diabetes and experiencing associated stigmas. This narrative review aimed to examine the literature on weight stigma across the preconception, pregnancy, and postpartum periods, specifically to (1) synthesize the evidence using a socioecological lens; (2) develop a conceptual model of weight stigma tailored to women across this life phase; and (3) provide recommendations for future research. To date, weight stigma research across the preconception, pregnancy, and postpartum periods has focused predominately on pregnancy and antenatal care. The drivers and facilitators of this stigma are pervasive, occurring across various contexts and settings. Manifestations of weight stigma include decreased reproductive healthcare quality, mental health symptoms, poorer health behaviors, and adverse pregnancy outcomes. Future research should further investigate the experiences of women preconception and postpartum, and health/social impacts beyond healthcare. The model herein will guide such research to ultimately identify opportunities for stigma reduction and improve multigenerational health and well-being outcomes.

Identifying target behaviors for weight management interventions for women who are overweight during pregnancy and the postpartum period: a qualitative study informed by the Behaviour Change Wheel

Background

Maternal overweight is increasing, and it is associated with several risk factors for both the mother and child. Healthy lifestyle behaviors adopted during pregnancy are likely to impact women’s health positively after pregnancy. The study’s aim was to identify and describe weight management behaviors in terms of the Capability, Opportunity and Motivation Behaviour (COM-B) -model to target weight management interventions from both the perspectives of women who are overweight and maternity care professionals.

Methods

This qualitative, descriptive study was conducted between 2019 and 2020. Individual interviews with pregnant and postpartum women who were overweight (n = 11) and focus group interviews with public health nurses (n = 5) were undertaken in two public maternity clinics in Southwest Finland. The data were analyzed using deductive content analysis consistent with the COM-B model.

Results

In the capability category, the women and the public health nurses thought that there was a need to find consistent ways to approach overweight, as it had often become a feature of the women’s identities. The use of health technology was considered to be an element of antenatal care that could be used to approach the subject of weight and weight management. Smart wearables could also support an evaluation of the women’s lifestyles. The opportunity category highlighted the lack of resources for support during perinatal care, especially after birth. Both groups felt that support from the family was the most important facilitating factor besides motivation. The women also expressed a conflict between pregnancy as an excuse to engage in unhealthy habits and pregnancy as a motivational period for a change of lifestyle. Furthermore, the women wanted to be offered a more robust stance on weight management and discreet counseling.

Conclusions

Our findings offer a theoretical basis on which future research can define intervention and implementation strategies. Such interventions may offer clear advice and non-judgmental support during pregnancy and after delivery by targeting women’s capabilities, opportunities, and motivation. Health technology could be a valuable component of intervention, as well as an implementation strategy, as they provide ways during maternity care to approach this topic and support women.

Prenatal care experiences among pregnant women with obesity in Wisconsin, United States: a qualitative quality improvement assessment

BACKGROUND

Stigma and bias experienced during prenatal care can affect quality of care and, ultimately, the health of pregnant women with obesity and their infants. We sought to 1) better understand the bias and stigma that women with BMIs ≥40 kg/m2 experience while receiving prenatal care, 2) gauge women's interest in group prenatal education for women with obesity, and 3) gather feedback about their preferred weight-related terminology.

METHODS

We conducted and thematically content-analyzed 30 semi-structured interviews of women with BMIs ≥40 kg/m2 who received prenatal care at a university-affiliated teaching hospital in the Midwest region of the United States.

RESULTS

All women recalled positive experiences during their perinatal care during which they felt listened to and respected by providers. However, many also described a fear of weight-related bias or recalled weight-based discrimination. Women reacted favorably to a proposed group prenatal care option for pregnant women with obesity that focused on nutrition, physical activity, and weight management. Women rated "weight" and "BMI" as the most desirable terms for describing weight, while "large size" and "obesity" were rated least desirable.

CONCLUSIONS

Many pregnant women with BMIs ≥40 kg/m2 experience bias in the prenatal care setting. Potential steps to mitigate bias towards weight include improving provider awareness of the experiences and perspectives of this population, expanding prenatal care options targeted towards women with high BMIs, including group care, and using patient-preferred weight-related terminology. Through the remainder of this manuscript, wherever possible, the term "high BMI" will be used in place of the term "obesity" to describe women with BMI ≥ 30 kg/m2 in order to respect the preferred terminology of the women we interviewed.
