Work as an Understudied Driver of Racial Inequities in Breastfeeding

Understanding the roles of state demographics and state policies in epidemiologic studies of maternal-child health disparities

Disparities in maternal-child health outcomes by race and ethnicity highlight structural differences in the opportunity for optimal health in the United States. Examples of these differences include access to state-level social policies that promote maternal-child health. States vary in their racial and ethnic composition as a result of the complex history of policies and laws related to slavery, Indigenous genocide and relocation, segregation, immigration, and settlement in the United States. States also vary in the social policies they enact. As a result, correlations exist between the demographic makeup of a state's population and the presence or absence of social policies in that state. These correlations become a mechanism by which racial and ethnic disparities in maternal-child health outcomes can operate. In this commentary, we use the example of 3 labor-related policies actively under consideration at state and federal levels (paid parental leave, paid sick leave, and reasonable accommodations during pregnancy) to demonstrate how correlations between state demographics and presence of these state policies could cause or exacerbate racial and ethnic disparities in maternal-child health outcomes. We conclude with a call for researchers to consider how the geographic distribution of racialized populations and state policies could contribute to maternal-child health disparities.

The role of clinic-based breastfeeding peer counseling on breastfeeding rates among low-income patients

BACKGROUND

Despite the benefits of breastfeeding (BF), rates remain lower than public health targets, particularly among low-income Black populations. Community-based breastfeeding peer counselor (BPC) programs have been shown to increase BF. We sought to examine whether implementation of a BPC program in an obstetric clinical setting serving low-income patients was associated with improved BF initiation and exclusivity.

METHODS

This is a quasi-experimental time series study of pregnant and postpartum patients receiving care before and after implementation of a BPC program in a teaching hospital affiliated prenatal clinic. The role of the BPC staff included BF classes, prenatal counseling and postnatal support, including in-hospital assistance and phone triage after discharge. Records were reviewed at each of 3 time points: immediately before the hire of the BPC staff (2008), 1-year post-implementation (2009), and 5 years post-implementation (2014). The primary outcomes were rates of breastfeeding initiation and exclusivity prior to hospital discharge, secondary outcomes included whether infants received all or mostly breastmilk during inpatient admission and by 6 weeks post-delivery. Bivariable and multivariable analyses were utilized as appropriate.

RESULTS

Of 302 patients included, 52.3% identified as non-Hispanic Black and 99% had Medicaid-funded prenatal care. While there was no improvement in rates of BF initiation, exclusive BF during the postpartum hospitalization improved during the 3 distinct time points examined, increasing from 13.7% in 2008 to 32% in 2014 (2009 aOR 2.48, 95%CI 1.13-5.43; 2014 aOR 1.82, 95%CI 1.24-2.65). This finding was driven by improved exclusive BF for patients who identified as Black (9.4% in 2008, 22.9% in 2009, and 37.9% in 2014, p = 0.01).

CONCLUSION

Inpatient BF exclusivity significantly increased with the tenure of a BPC program in a low-income clinical setting. These findings demonstrate that a BPC program can be a particularly effective method to address BF disparities among low-income Black populations.

Racializing Motherhood and Maternity Care in News Representations of Breastfeeding

Racial inequalities in breastfeeding have been a U.S. national concern, prompting health science research and public discourse. Social science research reveals structural causes, including racism in labor conditions, maternity care practices, and lactation support. Yet research shows that popular and health science discourses disproportionately focus on individual and community factors, blaming Black women and communities for unequal breastfeeding rates. This study examines how scientific reports are communicated to the public through a critical analysis of 104 U.S. news articles reporting research on racial disparities in breastfeeding. Findings show that articles acknowledge unequal treatment within maternity care but justify it by presenting Black patients as overburdening the maternity care systems they use due to low socioeconomic status, welfare dependency, poor family support, and poor health. Through these representations, articles co-construct racialized motherhood and maternity care systems in ways that hide manifestations of obstetric racism and combat social support for systemic change.

Structural Sexism and Breastfeeding in the United States, 2016-2021

INTRODUCTION

Recent studies demonstrate that structural sexism erodes women's health and impedes access to healthcare. This study extends this research to examine the relationship between structural sexism and breastfeeding initiation and duration in the United States.

METHOD

A multifaceted state-level structural sexism index was constructed and merged with responses from the 2016-2021 National Survey of Children's Health by state and child's birth year. For children ages six months to 5 years, the prevalence of being ever breastfed and breastfed for at least six months was measured across levels of structural sexism. Multivariable logistic regression analyzed the association of structural sexism with breastfeeding outcomes, net of individual and family characteristics.

RESULTS

Higher levels of structural sexism were associated with lower odds of breastfeeding initiation and lower odds of breastfeeding for at least six months net of family and child characteristics. In addition, sensitivity analyses show that variations in state breastfeeding laws did not explain these differences.

DISCUSSION

This study highlights structural sexism's role in limiting breastfeeding initiation and duration. Breastfeeding promotions and guidelines should consider the broader context of structural sexism.

Identifying occupational health inequities in the absence of suitable data: are there inequities in access to adequate bathrooms in US workplaces?

OBJECTIVES

Our research questions are often chosen based on the existence of suitable data for analysis or prior research in the area. For new interdisciplinary research areas, such as occupational health equity, suitable data might not yet exist. In this manuscript, we describe how we approached a research question in the absence of suitable data using the example of identifying inequities in adequate bathrooms in US workplaces.

METHODS

We created a conceptual model that hypothesises causal mechanisms for occupational health inequities, and from this model we identified a series of questions that could be answered using separate data sets to better understand inequities in adequate workplace bathrooms. Breaking up the analysis into multiple steps allowed us to use multiple data sources and analysis methods, which helped compensate for limitations in each data set.

RESULTS

Using the conceptual model as a guide, we were able to identify some jobs that likely have inadequate bathrooms as well as subpopulations potentially at higher risk for inadequate bathrooms. We also identified specific data gaps by reflecting on the challenges we faced in our multistep analysis. These gaps, which indicated future data collection needs, included difficulty finding data sources for some predictors of inadequate bathrooms that prevented us from fully investigating potential inequities.

CONCLUSIONS

We share our conceptual model and our example analysis to motivate researchers to avoid letting availability of data limit the research questions they pursue.

Factors associated with exclusive formula feeding among individuals with low-risk pregnancies in the United States

BACKGROUND

Better understanding of the factors associated with formula feeding during the hospital stay can help in identifying potential lactation problems and promote early intervention. Our aim was to ascertain factors associated with exclusive formula feeding in newborns of low-risk pregnancies.

METHODS

A population-based, retrospective study using the United States vital statistics datasets (2014-2018) evaluating low-risk pregnancies with a nonanomalous singleton delivery from 37 to 41 weeks. People with hypertensive disorders, or diabetes, were excluded. Primary outcome was newborn feeding (breast vs exclusive formula feeding) during hospital stay. Adjusted relative risks (aRRs) with 95% confidence intervals (CI) were calculated.

RESULTS

Of the 19 623 195 live births during the study period, 11 605 242 (59.1%) met inclusion criteria and among them, 1 929 526 (16.6%) were formula fed. Factors associated with formula feeding included: age < 20 years (aRR 1.31 [95% CI 1.31-1.32]), non-Hispanic Black (1.42, 1.41-1.42), high school education (1.69, 1.69-1.70) or less than high school education (1.94, 1.93, 1.95), Medicaid insurance (1.52, 1.51, 1.52), body mass index (BMI) < 18.5 (1.10, 1.09-1.10), BMI 25-29.9 (1.09, 1.09-1.09), BMI 30-34.9 (1.19, 1.19-1.20), BMI 35-39.9 (1.31, 1.30-1.31), BMI ≥ 40 (1.43, 1.42-1.44), multiparity (1.29, 1.29-1.30), lack of prenatal care (1.49, 1.48-1.50), smoking (1.75, 1.74-1.75), and gestational age (ranged from 37 weeks [1.44, 1.43-1.45] to 40 weeks [1.11, 1.11-1.12]).

CONCLUSIONS

Using a large cohort of low-risk pregnancies, we identified several modifiable factors associated with newborn feeding (eg, prepregnancy BMI, access to prenatal care, and smoking cessation). Improving the breast feeding initiation rate should be a priority in our current practice to ensure equitable care for all neonates.
