Road to Equity in Maternal and Child Health: Honoring the Past and Blazing New Paths.

PURPOSE: This paper is a historical account of an initiative, as recalled by the authors who were directly involved, that brought to the forefront the long-standing and unjust reproductive health inequities in the United States. It is composed of three distinct but interrelated parts that together map the past, present, and future of addressing racial inequities in Maternal and Child Health. DESCRIPTION: This paper is composed of three distinct but interrelated parts that together map the past, present, and future of addressing racial inequities in Maternal and Child Health. Part I recounts the history and achievements of a Centers for Disease for Control and Prevention initiative in the 1980-90's, led by the Prematurity Research Group in the Division of Reproductive Health, Pregnancy and Infant Health Branch. This initiative stimulated a paradigm shift in how we understand and address black infant mortality and the inequities in this outcome. Part II illustrates examples of some exemplary programmatic and policy legacies that stemmed either directly or indirectly from the Centers for Disease for Control and Prevention paradigm shift. Part III provides a discussion of how effectively the current practice in Maternal and Child Health applies this paradigm to address inequities and proposes a path for accelerating Title V agencies' progress toward birth equity. ASSESSMENT: This CDC initiative was transformative in that it raised the visibility of African American researchers, moved the field from a focus on traditional epidemiologic risks such as personal health promotion and medical interventions, to include racism as a risk factor for inequitable birth outcomes. The paradigm examined the specific roles of historical and structural racism, and the racialized, contextualized, and temporal exposures that are unique to Black women's experiences in the United States. CONCLUSION: The initiative radically changed the narratives about the underlying factors contributing to inequities in birth outcomes of Black women, altered the way we currently approach addressing inequities, and holds the keys for transforming practice to a more holistic and systematic approach to building sustained organizational structures in maternal and child health that accelerate the achievement of birth equity.

Preterm Birth and Receipt of Postpartum Contraception Among Women with Medicaid in North Carolina.

OBJECTIVES: To compare receipt of contraception and method effectiveness in the early postpartum period among women with and without a recent preterm birth (PTB). METHODS: We used data from North Carolina birth certificates linked to Medicaid claims. We assessed contraceptive claims with dates of service within 90 days of delivery among a retrospective cohort of women who had a live birth covered by Medicaid between September 2011 and 2012 (n = 58,201). To estimate the odds of receipt of contraception by PTB status (24-36 weeks compared to 37-42 weeks [referent]), we used logistic regression and tested for interaction by parity. To estimate the relationship between PTB and method effectiveness based on the Center for Disease Control and Prevention Levels of Effectiveness of Family Planning Methods (most, moderate and least effective [referent]), we used multinomial logistic regression. RESULTS: Less than half of all women with a live birth covered by Medicaid in North Carolina had a contraceptive claim within 90 days postpartum. Women with a recent PTB had a lower prevalence of contraceptive receipt compared to women with a term birth (45.7% vs. 49.6%). Women who experienced a PTB had a lower odds of receiving contraception. When we stratified by parity, women with a PTB had a lower odds of contraceptive receipt among women with more than two births (0.79, 95% CI 0.74-0.85), but not among women with two births or fewer. One-fourth of women received a most effective method. Women with a preterm birth had a lower odds of receiving a most effective method (0.83, 95% CI 0.77-0.88) compared to women with a term birth. CONCLUSIONS FOR PRACTICE: Contraceptive receipt was low among women with a live birth covered by Medicaid in North Carolina. To optimize contraceptive use among women at risk for subsequent preterm birth, family planning strategies that are responsive to women's priorities and context, including a history of preterm birth, are needed. SIGNIFICANCE: Access to free or affordable highly effective contraception is associated with reductions in preterm birth. Self-report data indicate that women with a very preterm birth (PTB) are less likely to use highly or moderately effective contraception postpartum compared to women delivering at later gestational ages. Using Medicaid claims data, we found that less than half of all women with a Medicaid covered delivery in North Carolina in 2011-2012 had a contraceptive claim within 90 days postpartum, and one fourth received a most effective method. Women with a PTB and more than two children were least likely to receive any method. Family planning strategies that are responsive to women's priorities and context, including a history of preterm birth, are needed so that women may access their contraceptive method of choice in the postpartum period.

The Other Side of Through: Young Breast Cancer Survivors' Spectrum of Sexual and Reproductive Health Needs.

The long-term reproductive health impact of cancer treatments is a concern for premenopausal women with a history of breast cancer. This study examined the unmet sexual and reproductive health needs of breast cancer survivors, as well as concordances and discordances in needs by childbearing status and race. We interviewed 17 women diagnosed with breast cancer between the ages of 18 and 45 years and living in North Carolina. To analyze these data, we used the Sort and Sift, Think and Shift© method, a multidimensional qualitative analysis approach. We learned that breast cancer survivors (a) received limited reproductive health information, (b) desired realistic expectations of conceiving postcancer, (c) struggled with adjusting to their altered physical appearance, and (d) had menopause symptoms that led to sexual health and quality of life issues. Breast cancer survivors are in need of and desire more education and resources to address their sexual and reproductive health concerns.

Dimensionality and R4P: A Health Equity Framework for Research Planning and Evaluation in African American Populations.

Introduction Existing health disparities frameworks do not adequately incorporate unique interacting contributing factors leading to health inequities among African Americans, resulting in public health stakeholders' inability to translate these frameworks into practice. Methods We developed dimensionality and R4P to integrate multiple theoretical perspectives into a framework of action to eliminate health inequities experienced by African Americans. Results The dimensional framework incorporates Critical Race Theory and intersectionality, and includes dimensions of time-past, present and future. Dimensionality captures the complex linear and non-linear array of influences that cause health inequities, but these pathways do not lend themselves to approaches to developing empirically derived programs, policies and interventions to promote health equity. R4P provides a framework for addressing the scope of actions needed. The five components of R4P are (1) Remove, (2) Repair, (3) Remediate, (4) Restructure and (5) Provide. Conclusion R4P is designed to translate complex causality into a public health equity planning, assessment, evaluation and research tool.

Prevalence of preterm, low birthweight, and small for gestational age delivery after breast cancer diagnosis: a population-based study.

BACKGROUND: Black-white disparities in breast cancer incidence rates and birth outcomes raise concerns about potential disparities in the reproductive health of premenopausal breast cancer survivors. We examined the prevalence of preterm birth (PTB), low birthweight (LBW), and small for gestational age (SGA) by breast cancer history and effect modification by race. METHODS: We analyzed linked North Carolina birth records and Central Cancer Registry files from 1990 to 2009 (n = 2,325,229). We used multivariable negative log-binomial regression to calculate prevalence ratios (PRs) and 95% confidence intervals (CIs) for the association between breast cancer history and PTB, LBW, and SGA. RESULTS: Of 1,912,269 eligible births, 512 births were to mothers with a previous breast cancer diagnosis history. Average age at breast cancer diagnosis was 31.8 years (SD = 4.7). Mean time from diagnosis to delivery was 3.3 years (SD = 2.8). After multivariable adjustment, the PR was 1.67 (95% CI, 1.42-1.97) for PTB, 1.50 (95% CI, 1.23-1.84) for LBW, and 1.30 (95% CI, 1.05-1.61) for SGA comparing women with a breast cancer history to the general population. Among black mothers, the PRs associated with breast cancer history for PTB, LBW, and SGA were 1.31 (95% CI, 1.00-1.72), 1.49 (95% CI, 1.14-1.94), and 1.44 (95% CI, 1.11-1.87), respectively. The corresponding PRs among white mothers were 2.06 (95% CI, 1.67-2.54), 1.53 (95% CI, 1.12-2.08), and 1.10 (95% CI, 0.77-1.58), respectively. The interaction between breast cancer history and race was statistically significant for associations with PTB, but not for LBW or SGA. CONCLUSIONS: In our data, women with a breast cancer history were at higher risk of delivering a PTB, LBW, or SGA infant, especially if they received chemotherapy or gave birth within 2 years of their breast cancer diagnosis date.

Cumulative Lactation and Onset of Hypertension in African-American Women.

Hypertension affects nearly 1 of 3 women and contributes to cardiovascular disease, the leading cause of death in the United States. Breastfeeding leads to metabolic changes that could reduce risks of hypertension. Hypertension disproportionately affects black women, but rates of breastfeeding among black women lag behind those in the general population. In the Black Women's Health Study (n = 59,001), we conducted a nested case-control analysis using unconditional logistic regression to estimate the association between breastfeeding and incident hypertension at ages 40-65 years using data collected from 1995 to 2011. Controls were frequency-matched 2:1 to 12,513 hypertensive women by age and questionnaire cycle. Overall, there was little evidence of association between ever breastfeeding and incident hypertension (odds ratio = 0.97, 95% confidence interval: 0.92, 1.02). However, age modified the relationship (P = 0.02): Breastfeeding was associated with reduced risk of hypertension at ages 40-49 years (odds ratio = 0.92, 95% confidence interval: 0.85, 0.99) but not at older ages. In addition, risk of hypertension at ages 40-49 years decreased with increasing duration of breastfeeding (P for trend = 0.08). Our results suggest that long-duration breastfeeding may reduce the risk of incident hypertension in middle age. Addressing breastfeeding as a potential preventative health behavior is particularly compelling because it is required for only a discrete period of time.

Predicting Preterm Birth Among Women Screened by North Carolina's Pregnancy Medical Home Program.

OBJECTIVE: To determine which combination of risk factors from Community Care of North Carolina's (CCNC) Pregnancy Medical Home (PMH) risk screening form was most predictive of preterm birth (PTB) by parity and race/ethnicity. METHODS: This retrospective cohort included pregnant Medicaid patients screened by the PMH program before 24 weeks gestation who delivered a live birth in North Carolina between September 2011-September 2012 (N = 15,428). Data came from CCNC's Case Management Information System, Medicaid claims, and birth certificates. Logistic regression with backward stepwise elimination was used to arrive at the final models. To internally validate the predictive model, we used bootstrapping techniques. RESULTS: The prevalence of PTB was 11 %. Multifetal gestation, a previous PTB, cervical insufficiency, diabetes, renal disease, and hypertension were the strongest risk factors with odds ratios ranging from 2.34 to 10.78. Non-Hispanic black race, underweight, smoking during pregnancy, asthma, other chronic conditions, nulliparity, and a history of a low birth weight infant or fetal death/second trimester loss were additional predictors in the final predictive model. About half of the risk factors prioritized by the PMH program remained in our final model (ROC = 0.66). The odds of PTB associated with food insecurity and obesity differed by parity. The influence of unsafe or unstable housing and short interpregnancy interval on PTB differed by race/ethnicity. CONCLUSIONS: Evaluation of the PMH risk screen provides insight to ensure women at highest risk are prioritized for care management. Using multiple data sources, salient risk factors for PTB were identified, allowing for better-targeted approaches for PTB prevention.

Disparities in infant mortality and effective, equitable care: are infants suffering from benign neglect?

Quality care for infant mortality disparity elimination requires services that improve health status at both the individual and the population level. We examine disparity reduction due to effective care and ask the following question: Has clinical care ameliorated factors that make some populations more likely to have higher rates of infant mortality compared with other populations? Disparities in postneonatal mortality due to birth defects have emerged for non-Hispanic black and Hispanic infants. Surfactant and antenatal steroid therapy have been accompanied by growing disparities in respiratory distress syndrome mortality for black infants. Progesterone therapy has not reduced early preterm birth, the major contributor to mortality disparities among non-Hispanic black and Puerto Rican infants. The Back to Sleep campaign has minimally reduced SIDS disparities among American Indian/Alaska Native infants, but it has not reduced disparities among non-Hispanic black infants. In general, clinical care is not equitable and contributes to increasing disparities.

Barriers to women's participation in inter-conceptional care: a cross-sectional analysis.

BACKGROUND: We describe participation rates in a special interconceptional care program that addressed all commonly known barriers to care, and identify predictors of the observed levels of participation in this preventive care service. METHODS: A secondary analysis of data from women in the intervention arm of an interconceptional care clinical trial in Philadelphia (n = 442). Gelberg-Andersen Behavioral Model for Vulnerable Populations to Health Services (herein called Andersen model) was used as a theoretical base. We used a multinomial logit model to analyze the factors influencing women's level of participation in this enhanced interconceptional care program. RESULTS: Although common barriers were addressed, there was variable participation in the interconceptional interventions. The Andersen model did not explain the variation in interconceptional care participation (Wald ch sq = 49, p = 0.45). Enabling factors (p = 0.058), older maternal age (p = 0.03) and smoking (p = < 0.0001) were independently associated with participation. CONCLUSIONS: Actively removing common barriers to care does not guarantee the long-term and consistent participation of vulnerable women in preventive care. There are unknown factors beyond known barriers that affect participation in interconceptional care. New paradigms are needed to identify the additional factors that serve as barriers to participation in preventive care for vulnerable women.

United States black:white infant mortality disparities are not inevitable: identification of community resilience independent of socioeconomic status.

INTRODUCTION: U.S. disparities in Black:White infant mortality are persistent. National trends, however, may obscure local successes. METHODS: Zero-corrected, negative binomial multivariable modeling was used to predict Black infant mortality (1999-2003) in all U.S. counties with reliable rates. Independent variables included county population size, racial composition, educational attainment, poverty, income and geographic origin. Resilient counties were defined as those whose Black infant mortality rate residual score was < 2.0. Mortality data was accessed from the Compressed Mortality File compiled by the National Center for Health Statistics and found on the CDC WONDER website. Demographic information was obtained from the US Census. RESULTS: The final model included the percentage of Blacks, age 18 to 64 years, speaking little or no English (P < .008), a socioeconomic index comprising educational attainment, poverty, and per capita income (P < .001), and household income in 1990 (P < .001). After accounting for these factors, a stratum comprising Essex and Plymouth Counties, Mass.; Bronx, N.Y.; and Multnomah, Ore. was identified as unusually resilient. Percentage of Black poverty and educational attainment in Black women in the resilient stratum approximated the average for all 330 counties. In 1979, Black infant mortality in the resilient stratum (23.6 per 1000 live births) exceeded Black US infant mortality (22.6). By 2001, Black infant mortality in the resilient stratum (5.6) was below the corresponding value for Whites (5.7). Resilient county neonatal mortality declined both early and late in the observation period, while post-neonatal declines were most marked after 1996. CONCLUSIONS: Models for reduction/elimination of racial disparities in US infant mortality, independent from county-level contextual measures of socioeconomic status, may already exist.

The Healthy African American Families (HAAF) project: from community-based participatory research to community-partnered participatory research.

During the past two decades, there has been an increased use of community-based participatory research in public health activities, especially as part of efforts to understand health disparities affecting communities of color. This article describes the history and lessons learned of a long-standing community participatory project, Healthy African American Families (HAAF), in Los Angeles, California. HAAF evolved from a partnership formed by a community advisory board, university, and federal health agency to an independent, incorporated community organization that facilitates and brokers research and health promotion activities within its community. HAAF created mechanisms for community education and networks of community relationships and reciprocity through which mutual support, research, and interventions are integrated. These sustained, institutionalized relationships unite resources and both community and scientific expertise in a community-partnered participatory research model to address multiple health problems in the community, including preterm birth, HIV, asthma, depression, and diabetes. The HAAF participatory process builds on existing community resiliency and resources and on centuries of self-help, problem-solving, cooperative action, and community activism within the African American community. HAAF demonstrates how community-partnered participatory research can be a mechanism for directing power, collective action, system change, and social justice in the process of addressing health disparities at the community level.

Where is the F in MCH? Father involvement in African American families.

OBJECTIVES: To: 1) review the historical contexts and current profiles of father involvement in African American families; 2) identify barriers to, and supports of, involvement; 3) evaluate the effectiveness of father involvement programs; and 4) recommend directions for future research, programs, and public policies. METHODS: Review of observational and interventional studies on father involvement. RESULTS: Several historical developments (slavery, declining employment for Black men and increasing workforce participation for Black women, and welfare policies that favored single mothers) led to father absence from African American families. Today, more than two thirds of Black infants are born to unmarried mothers. Even if unmarried fathers are actively involved initially, their involvement over time declines. We identified multiple barriers to, and supports of, father involvement at multiple levels. These levels include intrapersonal (eg, human capital, attitudes and beliefs about parenting), interpersonal (eg, the father's relationships with the mother and maternal grandmother), neighborhoods and communities (eg, high unemployment and incarceration rates), cultural or societal (eg, popular cultural perceptions of Black fathers as expendable and irresponsible, racial stratification and institutionalized racism), policy (eg, Earned Income Tax Credit, Temporary Assistance for Needy Families, child support enforcement), and life-course factors (eg, father involvement by the father's father). We found strong evidence of success for several intervention programs (eg, Reducing the Risk, Teen Outreach Program, and Children's Aid Society - Carrera Program) designed to prevent formation of father-absent families, but less is known about the effectiveness of programs to encourage greater father involvement because of a lack of rigorous research design and evaluation for most programs. CONCLUSION: A multi-level, life-course approach is needed to strengthen the capacity of African American men to promote greater involvement in pregnancy and parenting as they become fathers.

Achieving Breastfeeding Equity: A Study of a National Breastfeeding Initiative.

BACKGROUND: Equity in breastfeeding could reduce excess morbidity and mortality among children and mothers of color. Few programs that support breastfeeding have been evaluated for their capacity to create equity. The aim of this study was to assess the extent to which a diverse set of national breastfeeding programs actively promoted equity. SUBJECTS AND METHODS: Qualitative data collection was conducted between December 2012 and July 2013 by visits to 29 of 58 breastfeeding programs selected by the funder. Programs underwent a site visit with open-ended interviews of staff. Investigators used Atlas.ti software to code data and content analysis of qualitative evaluation data. Key categories and themes were identified to answer the questions: how do the programs conceptualize equity? and how do the organizations operationalize an approach to equity? RESULTS: Programs had widely divergent and often limited conceptualizations of equity. Nine categories describe the equity approaches' programs used. The social, political, and environmental contexts in which programs operated varied in the degree of challenge they pose for implementing equity-focused breastfeeding methods. We found only a few programs that matched the social, cultural, and economic realities and context of women of color. CONCLUSIONS: Breastfeeding equity programs need to explicitly define and envision outcomes, and need to identify equity inhibiting policies and practices. Equity attainment is more likely to emerge from institutional transformational processes that collaborate with the populations at risk. These findings have implications for other programs addressing equity in health.

DNA methylation of imprinted genes at birth is associated with child weight status at birth, 1 year, and 3 years.

Background: This study assessed the associations between nine differentially methylated regions (DMRs) of imprinted genes in DNA derived from umbilical cord blood leukocytes in males and females and (1) birth weight for gestational age z score, (2) weight-for-length (WFL) z score at 1 year, and (3) body mass index (BMI) z score at 3 years. Methods: We conducted multiple linear regression in n = 567 infants at birth, n = 288 children at 1 year, and n = 294 children at 3 years from the Newborn Epigenetics Study (NEST). We stratified by sex and adjusted for race/ethnicity, maternal education, maternal pre-pregnancy BMI, prenatal smoking, maternal age, gestational age, and paternal race. We also conducted analysis restricting to infants not born small for gestational age. Results: We found an association between higher methylation of the sequences regulating paternally expressed gene 10 (PEG10) and anthropometric z scores at 1 year (ß = 0.84; 95% CI = 0.34, 1.33; p = 0.001) and 3 years (ß = 1.03; 95% CI = 0.37, 1.69; p value = 0.003) in males only. Higher methylation of the DMR regulating mesoderm-specific transcript (MEST) was associated with lower anthropometric z scores in females at 1 year (ß = - 1.03; 95% CI - 1.60, - 0.45; p value = 0.001) and 3 years (ß = - 1.11; 95% CI - 1.98, - 0.24; p value = 0.01). These associations persisted when we restricted to infants not born small for gestational age. Conclusion: Our data support a sex-specific association between altered methylation and weight status in early life. These methylation marks can contribute to the compendium of epigenetically regulated regions detectable at birth, influencing obesity in childhood. Larger studies are required to confirm these findings.

Utilization of joint arthroplasty: racial and ethnic disparities in the Veterans Affairs Health Care System.

Studies within the Veterans Administration health care system have been very useful in identifying the existence of racial and ethnic disparities with regard to patient utilization of hip and knee joint arthroplasty. Existing studies have focused on three factors: estimates of joint arthroplasty utilization,postoperative outcomes, and patient-related variables (eg, expectations of and familiarity with the procedure, religious beliefs). Although Veterans Administration-based studies have produced helpful data, these data are limited because the populations studied are not representative of the larger US population. Specifically, studies from the Veterans Administration health care system are composed of a predominantly male patient demographic;in addition, patients are more likely to have lower income and education levels than the US population as a whole.
