The age-related patterns of preterm birth among urban African-American and non-Latina White mothers: The effect of paternal involvement

Mother-Father Relationship and Depressive Symptoms Among Pregnant Black Women

BACKGROUND

Black women report higher levels of depressive symptoms during pregnancy than white women. A supportive relationship with the father of the baby may be protective and decrease depressive symptoms.

OBJECTIVE

We sought to examine the association between mother-father relationship and depressive symptoms among pregnant black women.

METHODS

Using a cross-sectional design, we conducted a secondary data analysis from a subsample of 405 pregnant black women who participated in the Biosocial Impact on Black Births study, a prospective cohort study. Participants completed questionnaires at 19- to 29-week gestation, including 6 measures of their relationship with the father of the baby: (1) contact, (2) involvement, (3) overall relationship, (4) change in relationship from prior to pregnancy to during pregnancy, (5) support, and (6) conflict. Latent class analysis was used to identify and classify the relationship construct. The Center for Epidemiologic Studies-Depression (CES-D) scale was used, with scores ≥23 considered high levels of depressive symptoms. Data were analyzed with logistic regression.

RESULTS

Following adjustment for maternal sociodemographic characteristics, comorbid conditions, and health behaviors, women in a conflictual relationship had higher odds of having depressive symptom scores ≥23 (adjusted odds ratio: 3.50, 95% confidence interval: 2.00, 6.12) than those having no relationship (adjusted odds ratio: 2.81, 95% confidence interval: 1.43, 5.52), when compared with those with a good relationship.

CONCLUSIONS

These findings suggest that having either a conflictual or no relationship with the father of the baby during pregnancy increases the odds for higher maternal depressive symptoms (CES-D scores ≥ 23) among pregnant black women.

Association between hemoglobin A1c and asymptomatic carotid intima-media thickness in middle-aged and elderly populations without diabetes

BACKGROUND AND AIMS

Carotid atherosclerosis, including carotid artery intima-media thickness, plaques, and stenosis, is an important risk factor for stroke. However, the association between hemoglobin A1c (HbA1c) and carotid intima-media thickness (cIMT) was inconsistent. The aim of this study was to explore the association between HbA1c and the risk of increased cIMT among the Chinese population aged ≥40 years without diabetes.

METHODS AND RESULTS

A total of 3528 participants without diabetes from the China National Stroke Screen Survey program were enrolled in this study. cIMT was measured using duplex ultrasound examination. Logistic regression models were used to assess the association between HbA1c level and the risk of increased cIMT. A total of 565 (16.0%) participants had increased cIMT. After adjustment for other potential confounding factors, higher levels of HbA1c increased the risk of increased cIMT compared with the lowest level, and the odds ratios for quartile 2, quartile 3, and quartile 4 were 1.58, 1.67, and 1.98, respectively. Age had an interaction impact on the association between HbA1c level and the risk of increased cIMT.

CONCLUSION

In this large-scale and cross-sectional study, high-normal HbA1c was associated with the risk of increased asymptomatic cIMT in a rural Chinese population without diabetes, especially in individuals aged <60 years.

Does race or ethnicity play a role in the origin, pathophysiology, and outcomes of preeclampsia? An expert review of the literature

The burden of preeclampsia, a substantial contributor to perinatal morbidity and mortality, is not born equally across the population. Although the prevalence of preeclampsia has been reported to be 3% to 5%, racial and ethnic minority groups such as non-Hispanic Black women and American Indian or Alaskan Native women are widely reported to be disproportionately affected by preeclampsia. However, studies that add clarity to the causes of the racial and ethnic differences in preeclampsia are limited. Race is a social construct, is often self-assigned, is variable across settings, and fails to account for subgroups. Studies of the genetic structure of human populations continue to find more variations within racial groups than among them. Efforts to examine the role of race and ethnicity in biomedical research should consider these limitations and not use it as a biological construct. Furthermore, the use of race in decision making in clinical settings may worsen the disparity in health outcomes. Most of the existing data on disparities examine the differences between White and non-Hispanic Black women. Fewer studies have enough sample size to evaluate the outcomes in the Asian, American Indian or Alaskan Native, or mixed-race women. Racial differences are noted in the occurrence, presentation, and short-term and long-term outcomes of preeclampsia. Well-established clinical risk factors for preeclampsia such as obesity, diabetes, and chronic hypertension disproportionately affect non-Hispanic Black, American Indian or Alaskan Native, and Hispanic populations. However, with comparable clinical risk factors for preeclampsia among women of different race or ethnic groups, addressing modifiable risk factors has not been found to have the same protective effect for all women. Abnormalities of placental formation and development, immunologic factors, vascular changes, and inflammation have all been identified as contributing to the pathophysiology of preeclampsia. Few studies have examined race and the pathophysiology of preeclampsia. Despite attempts, a genetic basis for the disease has not been identified. A number of genetic variants, including apolipoprotein L1, have been identified as possible risk modifiers. Few studies have examined race and prevention of preeclampsia. Although low-dose aspirin for the prevention of preeclampsia is recommended by the US Preventive Service Task Force, a population-based study found racial and ethnic differences in preeclampsia recurrence after the implementation of low-dose aspirin supplementation. After implementation, recurrent preeclampsia reduced among Hispanic women (76.4% vs 49.6%; P<.001), but there was no difference in the recurrent preeclampsia in non-Hispanic Black women (13.7 vs 18.1; P=.252). Future research incorporating the National Institute on Minority Health and Health Disparities multilevel framework, specifically examining the role of racism on the burden of the disease, may help in the quest for effective strategies to reduce the disproportionate burden of preeclampsia on a minority population. In this model, a multilevel framework provides a more comprehensive approach and takes into account the influence of behavioral factors, environmental factors, and healthcare systems, not just on the individual.

Different maternal age patterns of preterm birth: Interplay of race/ethnicity, chronic stress, and marital status

The aim of this study was to examine whether the preterm birth (PTB) risks according to maternal age is altered by a woman's marital status and chronic stress among non-Hispanic (N-H) White, N-H Black, Hispanic, and Asian women. This researcher analyzed the Pregnancy Risk Assessment Monitoring System data for New York City and Washington State linked with the birth certificates for 2004-2007. The sample included 6344 singleton live births without birth defects to women aged 18 years or older identified as N-H White, N-H Black, Hispanic, or Asian. The outcome was PTB. Maternal age-specific PTB rates were calculated according to race/ethnicity, marital status, and chronic stress. Linear trends of PTB rates with maternal age were evaluated by the Mantel-Haenszel χ² test. Marriage had a protective effect against PTB at advancing maternal age across racial/ethnic groups. The health benefit of marriage was strong, particularly among the married N-H Black and Asian women, manifested as a maternal age-related decrease in the PTB rate (reverse-weathering). In contrast, women not married showed a maternal age-related increase in the PTB rate (weathering) across the racial/ethnic groups. Under higher chronic stress, married women generally experienced less weathering about PTB. These patterns were observed with noticeable racial/ethnic variations. Acknowledging the different dynamics among maternal age, marital status, and chronic stress by race/ethnicity could help shed light on the psychosocial mechanisms underlying the racial/ethnic inequalities in PTB in the United States. To that end, future studies should use more nuanced measurements of paternal support and chronic stress.

Maternal Adverse Childhood Experiences, Paternal Involvement, and Infant Health

OBJECTIVES

To assess the interplay between maternal exposure to adverse childhood experiences (ACEs) and father's acknowledgment of paternity (AOP; a proxy for paternal involvement) in the risk of low birth weight (<2500 grams) and preterm birth (<37 weeks) among offspring.

STUDY DESIGN

Data come from the 2018 North Dakota and South Dakota Pregnancy Risk Assessment Monitoring System (n = 1896). Logistic regression models were used to assess low birth weight and preterm birth outcomes. Moderation analyses are conducted to assess the interaction between maternal ACEs and father's AOP.

RESULTS

Moderation analyses demonstrated a positive interaction between an accumulating number of maternal ACEs and being unmarried without AOP for low birth weight and preterm birth. Upon comparing newborns of unmarried women without AOP, those whose mothers were exposed to 4 or more ACEs had a 3.74 times greater probability of low birth weight (0.050 vs 0.187) and a 1.74 times greater probability of preterm birth (0.085 vs 0.148) than those whose mothers reported no ACE exposure.

CONCLUSIONS

Exposure to accumulating ACEs substantially increases the risk of deleterious infant health outcomes, but only for newborns of unmarried women without AOP. Future research should assess the efficacy of interventions that can mitigate the impact of maternal ACEs in the absence of father's AOP.

Disparities in Cardiovascular Disease Outcomes Among Pregnant and Post-Partum Women

Background

The incidence of cardiovascular disease among pregnant women is rising in the United States. Data on racial disparities for the major cardiovascular events during pregnancy are limited.

Methods and Results

Pregnant and post‐partum women hospitalized from January 2007 to December 2017 were identified from the Nationwide Inpatient Sample. The outcomes of interest included: in‐hospital mortality, myocardial infarction, stroke, pulmonary embolism, and peripartum cardiomyopathy. Multivariate regression analysis was used to assess the independent association between race and in‐hospital outcomes. Among 46 700 637 pregnancy‐related hospitalizations, 21 663 575 (46.4%) were White, 6 302 089 (13.5%) were Black, and 8 914 065 (19.1%) were Hispanic. The trends of mortality and stroke declined significantly in Black women, but however, were mostly unchanged among White women. The incidence of mortality and cardiovascular morbidity was highest among Black women followed by White women, then Hispanic women. The majority of Blacks (62.3%) were insured by Medicaid while the majority of White patients had private insurance (61.9%). Most of Black women were below‐median income (71.2%) while over half of the White patients were above the median income (52.7%). Compared with White women, Black women had the highest mortality with adjusted odds ratio (aOR) of 1.45, 95% CI (1.21–1.73); myocardial infarction with aOR of 1.23, 95% CI (1.06–1.42); stroke with aOR of 1.57, 95% CI (1.41–1.74); pulmonary embolism with aOR of 1.42, 95% CI (1.30–1.56); and peripartum cardiomyopathy with aOR of 1.71, 95 % CI (1.66–1.76).

Conclusions

Significant racial disparities exist in major cardiovascular events among pregnant and post‐partum women. Further efforts are needed to minimize these differences.
