Weight Stigma Related to Pregnancy: A Concept Analysis

Fear of Childbirth Among Pregnant People Facing Anti-Fat Bias

Explicit and implicit anti-fat biases are widespread among healthcare providers, leading to significant negative consequences for pregnant people, including poorer health outcomes. Fear of childbirth (FOC) can affect the length of labor, increase the risk of cesarean delivery, and negatively influence a new parent's perception of infant bonding. This study investigated the impact of perceived anti-fat bias on FOC among pregnant people. Data were gathered from 329 pregnant people recruited from three large academic prenatal centers in the United States and via social media. Participants completed a survey that included validated instruments measuring perceptions of anti-fat bias and FOC. Participants perceiving anti-fat bias reported higher FOC. Black participants perceiving anti-fat bias reported higher FOC. These findings suggest that perceived anti-fat bias from providers is associated with FOC for pregnant people, particularly those who identify as Black. Interventions to educate providers on these important concepts could help improve pregnant people's experience within the healthcare system.

The relationship between body mass index and perceived control over labor

BACKGROUND

Individuals with an increased body mass index (BMI) (≥ 30 kg/m2) experience higher rates of perinatal mental health disorders than individuals with BMI < 30. Personal experience of decreased control over labor has been associated with the development postpartum mood and anxiety disorders. However, no studies have investigated the association between BMI and experience of control over labor. This study aimed to assess perceived control over labor and compare patients with BMI ≥ 30 to those with BMI < 30.

METHODS

We performed a secondary analysis of a cross-sectional study of postpartum patients who delivered at term (37-41 weeks gestation). Postpartum, participants completed the Labour Agentry Scale (LAS), a validated tool to assess perceived control over labor/birth. Demographic, maternal health history and obstetric/neonatal outcomes were abstracted from the patient chart. Bivariate analyses were performed between those with BMI < 30 and those with BMI ≥ 30 using Fisher's exact test. Continuous LAS scores were compared between patients with BMI < 30 and BMI ≥ 30 using Wilcoxon rank-sum tests. Higher LAS scores indicate higher perceived control over labor. Multivariable linear regression was then performed to account for confounding factors identified a priori.

RESULTS

There was no difference in LAS between those with BMI ≥ 30 and BMI < 30. When stratified by World Health Organization (WHO) class of BMI, those with BMI ≥ 40 had a significantly lower LAS scores than those with BMI < 30 (147 vs. 163, p = 0.02), however, this finding was no longer significant after controlling for length of labor and cesarean birth.

CONCLUSION

Only participants with the highest BMI experienced decreased control over labor, and this finding was no longer significant after controlling for mode of delivery and length of labor. Further research into the experience of birthing people with BMI ≥ 30 is critical to understand the increased risk of perinatal mood disorders among this population.

Body Mass Index and Perceived Labor Control: Could weight stigma explain differences in birth experience?

Background

Individuals with a body mass index (BMI) of ≥ 30 kg/m2 experience weight stigma when interacting with the healthcare system. There is limited data on how weight stigma impacts patient's experience of obstetric care. This study aims to assess perceived control over the birth process and compare patients with BMI ≥ 30 to those with BMI < 30.

Methods

We performed a secondary analysis of a cross-sectional study of term patients. Postpartum, participants completed the Labour Agentry Scale (LAS), a validated tool to assess perceived control over labor/birth. Continuous LAS scores were compared between patients with BMI < 30 and BMI ≥ 30.

Results

There was no difference in LAS between those with BMI ≥ 30 and BMI < 30. When stratified by World Health Organization (WHO) class of BMI, those with BMI ≥ 40 had a significantly lower LAS scores than those with BMI < 30 (147 vs. 163, p = 0.02), however, this finding was no longer significant after controlling for length of labor and cesarean birth.

Conclusion

Only participants with the highest BMI experienced decreased control over labor, and this finding was no longer significant after controlling for mode of delivery and length of labor. Further research is necessary into how weight stigma influences birthing people's experience.

Close Relationships as Sources of Pregnancy-Related Weight Stigma for Expecting and New Mothers

BACKGROUND

Experiencing weight stigma during pregnancy is detrimental to psychosocial health outcomes, including increasing maternal stress and undermining engagement in health behaviors. Guided by a recent socioecological framework, close interpersonal relationships are integral in pregnancy to facilitate healthy behaviors and protect maternal mental health, but they may also be sources that project weight stigma. The purpose of this study was to characterize weight stigma experienced during pregnancy and postpartum from close relationships including partners, immediate family, extended family, and friends.

METHOD

Women who were pregnant or up to 1 year postpartum completed a survey that assessed sources of weight stigma since becoming pregnant. A thematic analysis was performed to code open-ended responses to understand the lived experiences of pregnancy-related weight stigma experienced from close relations.

RESULTS

Of the 501 women who completed the online survey, 157 indicated experiencing weight stigma from close relations. Average frequency of weight stigma from close relations was 1.83 ("less than once a month" to "a few times a month"). Weight-stigmatizing examples from close relations during pregnancy included negative assumptions about maternal or fetal health and maternal lifestyle behaviors based on weight gain; comparing women to pregnant body ideals; and making comments that resulted in women judging themselves poorly as a pregnant individual or mother.

CONCLUSIONS

Close relationships can be sources of pregnancy-related weight stigma. This may not only increase risk for adverse stigma-related consequences, but also could cut off the important benefits of maternal social support resulting in poor mental health outcomes and health behaviors.

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.
