RESUMO
BACKGROUND: Stress during pregnancy adversely impacts maternal and infant health. Dysregulation of the hypothalamic pituitary axis is a mediator of the relationship between stress and health. Evidence supporting an association between prenatal chronic stress and cortisol is limited, and the majority of research published has been conducted amongst White participants, who experience less chronic stress than people of color. AIM: This study investigated associations between various measures of prenatal stress and hair cortisol concentrations which is a biomarker of the integrated stress response in a sample of Latina participants during the third trimester of pregnancy. METHOD: Pregnant women (n=45) were surveyed with scales measuring chronic stress, perceived stress, pregnancy-related and pregnancy-specific anxiety. Hair samples were collected as an objective neuroendocrine measure of chronic stress. Linear regression analyses were performed to assess associations between stress measures and hair cortisol. Pre-pregnancy BMI, smoking during pregnancy, and steroid use during pregnancy were used as covariates in adjusted models. RESULTS: Chronic stress, operationalized as maternal reports of neighborhood/housing strain, daily activities and relationship strain, discrimination, and financial strain, was significantly associated with higher hair cortisol concentrations. No significant associations were found between hair cortisol and perceived stress, pregnancy-related anxiety, nor pregnancy-specific anxiety in adjusted models. CONCLUSION: Chronic stress may be a more robust correlate of physiological stress, as measured by hair cortisol in pregnancy, than other common measures of prenatal stress and anxiety.

BACKGROUND: We examined whether women with prenatal mood and anxiety disorders would exhibit differential pro- and anti-inflammatory marker trajectories during the prenatal and postpartum periods compared to women without these disorders. METHODS: Approximately 179 pregnant women participated in a longitudinal study conducted in two urban areas. Blood samples for inflammatory markers were collected at six study visits. The Structured Clinical Interview for the DSM-IV (SCID) was administered to participants scoring above cutoffs on anxiety and depression. Pregnant women with SCID Axis I diagnoses of mood and/or anxiety disorders were compared to other participants on inflammatory markers. Multilevel modeling tested associations between SCID diagnoses and within-person interleukin (IL)6 and IL10 trajectories. RESULTS: Prenatal SCID diagnoses were associated with linear, quadratic and cubic change in IL6 from prenatal to postpartum timepoints. Women with a prenatal SCID diagnosis had steeper decreases and increases in IL6 during prenatal and postpartum periods. SCID diagnoses were associated with lower IL10 in mid-pregnancy to postpartum (b = -0.078, SE = 0.019; p = .015). LIMITATIONS: Future studies would benefit from a larger sample size and a larger number of participants with SCID diagnoses. Future research should also examine whether different prenatal Axis 1 diagnoses are associated with different patterns of immune response in pregnancy. CONCLUSIONS: Pregnant women with prenatal mood and anxiety disorders had greater fluctuations in IL6 across prenatal and postpartum periods and lower IL10 through pregnancy and postpartum. They may have different proinflammatory states that remain after birth without a reciprocal anti-inflammatory response.

OBJECTIVE: Parental trauma exposure and trauma-related distress can increase risk for adverse health outcomes in offspring, but the pathways implicated in intergenerational transmission are not fully explicated. Accelerated biological aging may be one mechanism underlying less favorable health in trauma-exposed individuals and their offspring. This study examines associations of preconception maternal and paternal posttraumatic stress disorder (PTSD) symptoms with child telomere length, and maternal prenatal C-reactive protein (CRP) as a biological mechanism. METHODS: Mothers (n = 127) and a subset of the fathers (n = 84) reported on PTSD symptoms before conception. Mothers provided blood spots in the second and third trimester that were assayed for CRP. At age 4, children provided buccal cells for measurement of telomere length. Models adjusted for parental age, socioeconomic status, maternal pre-pregnancy BMI, child biological sex, and child age. RESULTS: Mothers' PTSD symptoms were significantly associated with shorter child telomere length (ß = -0.22, SE = 0.10, p = .023). Fathers' PTSD symptoms were also inversely associated with child telomere length (ß = -0.21, SE = 0.11), though nonsignificant (p = .065). There was no significant indirect effect of mothers' PTSD symptoms on child telomere length through CRP in pregnancy, but higher second trimester CRP was significantly associated with shorter child telomere length (ß = -0.35, SE = 0.18, p = .048). CONCLUSIONS: Maternal symptoms of PTSD prior to conception and second trimester inflammation were associated with shorter telomere length in offspring in early childhood, independent of covariates. Findings indicate intergenerational transmission of parental trauma may occur in part through accelerated biological aging processes and provide further evidence that prenatal pro-inflammatory processes program child telomere length.Open Science Framework Pre-registration:https://osf.io/7c2d5/?view_only=cd0fb81f48db4b8f9c59fc8bb7b0ef97.
RESUMO
OBJECTIVE: Interdependence with family is considered a core element of collectivistic cultures, and it is routinely endorsed by people of ethnic/racial minority backgrounds in the United States. In contrast, a preference for independence from family is characteristic of individualistic cultures, and of European Americans, who are considered prototypical of cultural individualism. Scholars have also theorized that socioeconomic factors play a role in shaping these patterns. We hypothesized and tested the possibility of a more nuanced and interactive pattern. Drawing from long-standing research on U.S. ethnic-minority cultures and recent research on social class, we expected that lower income would be least associated with family interdependence in foreign-born Latino/a Americans and most strongly associated with higher family interdependence in European Americans. METHOD AND RESULTS: In a prospective community study of a diverse sample of U.S. adults (N = 2,466), income interacted with ethnic/racial group to predict interdependence with family. In line with our predictions, income was not associated with family interdependence for foreign-born Latino/a Americans or African Americans, but lower income was significantly associated with higher interdependence with family in European Americans and, to a lesser extent, in U.S.-born Latino/a Americans. CONCLUSIONS: These findings provide novel evidence for the relevance of both ethnicity/race and social class-two aspects of culture-for family interdependence. They highlight the centrality of interdependence with family among foreign-born Latino/a Americans while showing that European Americans, a group considered most representative of cultural individualism, can also highly value interdependence with family.

RESUMO
The current study investigates whether prepregnancy maternal posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, and stress predict children's cortisol diurnal slopes and cortisol awakening responses (CARs) adjusting for relevant variables. Mothers were enrolled after delivering a baby and followed through their subsequent pregnancy with 5 years of longitudinal data on their subsequent child. This prospective design allowed assessment of PTSD symptoms, depressive symptoms, and perceived stress prior to pregnancy. Children provided three saliva samples per day on three consecutive days at two timepoints in early childhood (M age = 3.7 years, SD = 0.38; M age = 5.04 years, SD = 0.43). Mothers' PTSD symptoms prior to pregnancy were significantly associated with flatter child diurnal cortisol slopes at 4 and 5 years, but not with child CAR. Findings at the age of 4 years, but not 5 years, remained statistically significant after adjustment for maternal socioeconomic status, race/ethnicity, child age, and other covariates. In contrast, maternal prepregnancy depressive symptoms and perceived stress did not significantly predict cortisol slopes or CAR. Results suggest that maternal prepregnancy PTSD symptoms may contribute to variation in early childhood physiology. This study extends earlier work demonstrating risk of adverse outcomes among children whose mothers experienced trauma but associations cannot be disentangled from effects of prenatal mental health of mothers on children's early childhood.

Objectives: Prior research indicates that Latinas are at risk for experiencing high levels of anxiety during pregnancy. Pregnancy anxiety is a specific affective experience involving fears and worries about one's current pregnancy and it has been linked to heightened risk for preterm birth and developmental effects. Despite this concerning pattern, research has rarely examined Latina beliefs about the transition to motherhood and little is known about specific sources of pregnancy anxiety in Latinas, including whether fears are rooted in cultural concerns. The present study investigates the experiences of pregnancy anxiety among Latinas and explores their broader cultural beliefs surrounding pregnancy. Methods: Fourteen pregnant Latinas articulated their experience of pregnancy anxiety, how they coped with their anxiety, and the beliefs they held surrounding pregnancy in 11 individual interviews and one focus group of three participants, all conducted in Spanish. Results: Thematic analysis revealed that overall, Latinas felt that anxiety during pregnancy was normal, and that they worried about labor and delivery, losing their baby, their baby being born with a birth defect, and felt affected by the broader sociopolitical climate. Latinas felt lucky to be pregnant, believed that pregnancy was a blessing from God, and stressed the importance of maintaining a healthy pregnancy. Themes about family involvement and culturally-driven privileged status also emerged. Conclusions: The present study highlights specific themes that may be important to consider in the context of Latina perinatal health. Such findings set the stage for future investigations examining the experience of anxiety specific to pregnancy in Latinas.
Objetivos: Investigaciones anteriores indican que las latinas corren el riesgo de experimentar altos niveles de ansiedad durante el embarazo. La ansiedad relacionada con el embarazo es una experiencia afectiva específica que involucra temores y preocupaciones y se ha relacionado con un mayor riesgo de parto prematuro y consecuencias en el desarrollo. A pesar de este patrón preocupante, rara vez se han examinado las creencias de gestantes latinas sobre la transición a la maternidad y se sabe poco sobre las fuentes específicas de ansiedad relacionada con el embarazo entre las latinas, incluso si los temores tienen sus raíces en inquietudes culturales. El presente estudio investiga las experiencias de ansiedad relacionada con el embarazo en gestantes latinas y explora sus creencias culturales más amplias en torno al embarazo. Métodos: Catorce latinas embarazadas expresaron su experiencia de ansiedad relacionada con el embarazo, las formas en que lidiaron con dicha ansiedad y las creencias que tenían sobre el embarazo en 11 entrevistas individuales y un grupo de enfoque de tres participantes, todas realizadas en español. Resultados: El análisis temático reveló que, en general, las gestantes latinas sentían que la ansiedad relacionada con el embarazo era normal y que estaban preocupadas por el parto, la pérdida de su bebé, que su bebé naciera con un defecto de nacimiento y se sentían afectadas por el ambiente sociopolítico más amplio. Las latinas se sintieron afortunadas de estar embarazadas, creían que el embarazo era una bendición de Dios y enfatizaron la importancia de mantener un embarazo saludable. También surgieron temas sobre la participación familiar y el estatus privilegiado impulsado por la cultura. Conclusiones: El presente estudio destaca temas específicos que pueden ser importantes a considerar en el contexto de la salud perinatal de las latinas. Dichos hallazgos sientan las bases para futuras investigaciones que examinen la experiencia de ansiedad específica relacionada con el embarazo entre las latinas.
RESUMO
BACKGROUND AND AIM: Resilience resources are associated with positive mental and physical health outcomes. However, we know little about protective factors in low-income or racially or ethnically diverse populations of men. This study examined socioeconomic status and racial/ethnic differences in resilience resources among low-income Black, Latino, and White fathers of infants. METHODS: The Community Child Health Network conducted a cohort study of mothers and fathers in five sites across the U.S. A sample of fathers who identified as Black, Latino/Hispanic, or non-Hispanic White were recruited and interviewed at home on three occasions during the first year of parenting (n = 597). Several resilience resources were assessed: mastery, self-esteem, dispositional optimism, approach-oriented coping style, positive affect, social support, and spirituality. The first five resources were interrelated and scored as a composite. RESULTS: Multivariate analyses adjusted for covariates indicated that Black fathers had higher scores on the resilience resources composite compared to White and Latino fathers. Black fathers were also highest in spirituality, followed by Latino fathers who were higher than White fathers. There were significant interactions between race/ethnicity with income and education in predicting optimism, spirituality, and self-esteem. Higher education was associated with higher scores on the resilience resources composite and spirituality in Black fathers, and higher education was associated with higher self-esteem in Black and Latino fathers. Higher income was associated with higher optimism in White fathers. CONCLUSION: These results indicate that levels of individual resilience factors are patterned by income, education, and race/ethnicity in low-income fathers, with many possible implications for research and policy.

BACKGROUND: Insufficient sleep has been linked to accelerated biological aging in adults, providing a possible mechanism through which sleep may influence disease risk. In the current paper, we test the hypothesis that short sleep in postpartum would predict older biological age in women one year post birth, as indicated by accelerated epigenetic aging. METHODS: As part of a larger study of pregnancy and postpartum health (Healthy Babies Before Birth, HB3), 33 mothers provided blood samples for epigenetic aging clock estimates. intrinsic epigenetic age acceleration (IEAA), extrinsic apigenetic age acceleration, phenotypic epigenetic age acceleration (PEAA), GrimAge, DNAmPAI-1, and DNAm telomere length (TL) were calculated using established protocols. Sleep duration was categorized as insufficient sleep (<7 hours per night) or healthy sleep duration (7+ hours per night). Sleep quality was determined using the Pittsburgh Sleep Quality Index (Global score >5). RESULTS: Maternal postpartum sleep duration at 6 months, but not 12 months, following a birth was predictive of older 12-month IEAA, B (SE) = 3.0 (1.2), P = .02, PEAA, B (SE) = 7.3 (2.0), P = .002, and DNAmTL, B (SE) = -0.18 (0.07), P = .01, but not other indices, all P> .127. Self-reported poor sleep quality at 6 and 12 months was not significantly related to epigenetic age. CONCLUSIONS: These findings suggest that insufficient sleep duration during the early postpartum period is associated with accelerated biological aging. As the sample size is small, additional research is warranted with a larger sample size to replicate these findings.

BACKGROUND: Maternal stress during pregnancy can influence the trajectory of fetal development, shaping offspring physiology and health in enduring ways. Some research implicates fetal programming of the hypothalamic-pituitary-adrenocortical (HPA) axis as a mediator of these effects. The present study is the first to examine child hair cortisol concentration (HCC) and maternal stress during pregnancy in a diverse, low-income sample. METHODS: The sample consisted of 77 healthy, low-income (M annual income: $13,321), mother-children pairs (M child ageâ¯=â¯3.81 years, SD = 0.43). The children were 57 % girls, 43 % boys. Mothers were 65 % Latina/Hispanic, 28 % Non-Hispanic White, 7% Black/African American. Maternal prenatal stress was measured with the Perceived Stress Scale administered by interview in the second and third trimesters, and again approximately four years later when child hair samples for assaying HCC were collected. RESULTS: On average maternal perceived stress increased significantly across pregnancy, then returned to lower levels 4 years after birth. Regression analysis revealed that child HCC was not significantly predicted by maternal perceived stress at either single prenatal time point. Exploratory analysis revealed evidence of a relation between increases in maternal prenatal stress from second to third trimester and child HCC four years later (râ¯=â¯.37, pâ¯=⯠.04). CONCLUSIONS: These results suggest that measures of prenatal maternal stress at any one time point may not be predictive of offspring long-term HPA output in low-income child samples, but that increases in stress levels across pregnancy may provide important information undetected by individual time point measures.

BACKGROUND: Dysregulations in maternal hypothalamus-pituitary-adrenal function and the end product, cortisol, have been associated with a heightened risk for stress-related health complications during pregnancy and post partum. Given the adverse health impact that maternal cortisol may have on expectant mothers and their infants, empirically-based prenatal interventions are needed to target optimal management of stress and its biological effects in at-risk pregnant women, a primary example of which is cognitive behavioral stress management (CBSM). This randomized-controlled trial examined the effects of a prenatal CBSM intervention on reduction in perceived stress and regulation of salivary cortisol patterns [i.e., overall cortisol output (area under the curve), cortisol awakening response (CAR), diurnal slope] during pregnancy and the early postpartum period, as compared to a control group. METHODS: One hundred low-income pregnant women (71% Latina; 76% annual income < $20 K) with low or high anxiety during pregnancy were randomized (stratified by anxiety) to either an eight-week CBSM group intervention (n = 55) or a control group (n = 45). They provided seven salivary cortisol samples (four am samples, 12 pm, 4 pm, and 8 pm samples on one collection day) at baseline (1st trimester; < 17 weeks of gestation), after their prenatal program (2nd trimester), and also in the third trimester and at three months post partum. RESULTS: Women receiving CBSM had lower perceived stress levels throughout pregnancy and early post partum compared to women in the control group (p = .020). Among women with high prenatal anxiety, those in CBSM showed a steeper decline in their diurnal cortisol at three months post partum compared to those in the control group (p = .015). Further, non-Latina women in CBSM had a lower CAR at three months post partum compared to non-Latina women in the control group (p = .025); these randomization group differences on the CAR were not observed among Latina women. CONCLUSIONS: These findings provide preliminary support for the efficacy of prenatal CBSM interventions in improving stress outcomes among low-income pregnant women and suggest the need to test the effects of these interventions on a larger scale for improving maternal and infant health outcomes long-term.

OBJECTIVE: Allostatic load (AL) represents multisystem physiological "wear-and-tear" reflecting emerging chronic disease risk. We assessed AL during the first year postpartum in a diverse community sample with known health disparities. STUDY DESIGN: The Eunice Kennedy Shriver National Institute for Child Health and Human Development Community Child Health Network enrolled 2,448 predominantly low-income African-American, Latina, and White women immediately after delivery of liveborn infants at ≥20 weeks' gestation, following them over time with interviews, clinical measures, and biomarkers. AL at 6 and 12 months postpartum was measured by body mass index, waist:hip ratio, blood pressure, pulse, hemoglobin A1c, high-sensitive C-reactive protein, total cholesterol and high-density lipoprotein, and diurnal cortisol slope. RESULTS: Adverse AL health-risk profiles were significantly more prevalent among African-American women compared with non-Hispanic Whites, with Latinas intermediate. Breastfeeding was protective, particularly for White women. Complications of pregnancy were associated with higher AL, and disparities persisted or worsened through the first year postpartum. CONCLUSION: Adverse AL profiles occurred in a substantial proportion of postpartum women, and disparities did not improve from birth to 1 year. Breastfeeding was protective for the mother.

Most health research focuses on the independent associations of positive or negative aspects of close relationships with health outcomes. A small but growing literature has begun to examine interactive effects of positive and negative aspects. These interactive effects frequently predict health independently or above-and-beyond main effects of either the positive or the negative aspects, suggesting unique relationship processes or emergent features of these close relationship patterns. Our goal in this review is to lay out the existing approaches to studying the interactive effects of positive and negative aspects of close relationships, and to review available evidence linking these interactive effects to health outcomes. We conclude by discussing important unresolved issues and highlighting critical directions for future research.
RESUMO
This study evaluated the relationship between sleep quality and symptoms of depression and anxiety in women studied in pregnancy and postpartum. Scores on standardized measures of sleep (PSQI) at 6 months postpartum, and symptoms of anxiety and depression (OASIS, the PHQ9, and EPDS) were assessed by structured interviews in 116 women in pregnancy and/or postpartum. Poor sleep quality was significantly associated with greater symptoms of depression and anxiety. Women who had significantly higher OASIS (anxiety) scores (ß = .530, p < .001), PHQ9 (depression) scores (ß = .496, p < .001), and EPDS (postpartum depression and anxiety) scores (ß = .585, p < .001) also had elevated total PSQI scores after adjustment for covariates, including prenatal depression and anxiety scores. Though inferences about causality are not feasible, these results support emerging research showing sleep quality is a risk factor for negative maternal affect in the postpartum period. Assessment of maternal sleep hygiene is worth consideration as a component of identifying women at risk for postpartum depression and anxiety.

OBJECTIVE: We hypothesized second trimester serum cortisol would be higher in spontaneous preterm births compared to provider-initiated (previously termed 'medically indicated') preterm births. STUDY DESIGN: We used a nested case-control design with a sample of 993 women with live births. Cortisol was measured from serum samples collected as part of routine prenatal screening. We tested whether mean-adjusted cortisol fold-change differed by gestational age at delivery or preterm birth subtype using multivariable linear regression. RESULT: An inverse association between cortisol and gestational age category (trend p = 0.09) was observed. Among deliveries prior to 37 weeks, the mean-adjusted cortisol fold-change values were highest for preterm premature rupture of the membranes (1.10), followed by premature labor (1.03) and provider-initiated preterm birth (1.01), although they did not differ statistically. CONCLUSION: Cortisol continues to be of interest as a marker of future preterm birth. Augmentation with additional biomarkers should be explored.

Following the birth of an infant, decreases in testosterone and increases in depressive symptoms have been observed in fathers. Paternal testosterone may reflect fathers' investment in pair-bonding and paternal caregiving and, as such, may be associated with maternal and familial well-being. This study tests associations between paternal testosterone, paternal and maternal postpartum depressive symptoms, and subsequent family functioning. Within 149 couples, fathers provided testosterone samples when infants were approximately nine months old and both parents reported on postpartum depressive symptoms at two, nine, and 15months postpartum. Fathers with lower aggregate testosterone reported more depressive symptoms at two and nine months postpartum. Mothers whose partners had higher evening testosterone reported more depressive symptoms at nine and 15months postpartum. Maternal relationship satisfaction mediated this effect, such that mothers with higher testosterone partners reported more relationship dissatisfaction, which in turn predicted more maternal depressive symptoms. Higher paternal testosterone and paternal depressive symptoms at nine months postpartum each independently predicted greater fathering stress at 15months postpartum. Higher paternal testosterone also predicted more mother-reported intimate partner aggression at 15months postpartum. In addition to linear relationships between testosterone and depression, curvilinear relationships emerged such that fathers with both low and high testosterone at nine months postpartum reported more subsequent (15-month) depressive symptoms and fathering stress. In conclusion, whereas higher paternal testosterone may protect against paternal depression, it contributed to maternal distress and suboptimal family outcomes in our sample. Interventions that supplement or alter men's testosterone may have unintended consequences for family well-being.

Postpartum depression is a major mental health issue for women and society. We examined stability and change in symptoms of depression over two consecutive pregnancies and tested life stress as a potential mechanism. The Community Child Health Network followed an ethnically/racially diverse sample from one month after a birth for two years. A subset of 228 women had a second birth. Interview measures of depression symptoms (EPDS) and life stress (life events, perceived stress, chronic stress, interpersonal aggression) were obtained during home visits. Three-quarters of the sample showed intra-individual stability in depressive symptoms from one postpartum period to the next, and 24% of the sample had clinically significant symptoms after at least one pregnancy (9% first, 7.5% second, 3.5% both). Each of the four life stressors significantly mediated the association between depressive symptoms across two postpartum periods. Stress between pregnancies for women may be an important mechanism perpetuating postpartum depression.
RESUMO
BACKGROUND: Early parenthood is a time of chronic sleep disturbance and also of heightened depression risk. Poor sleep quality has been identified both as a predictor of postpartum depressive symptoms and as a consequence. PURPOSE: This study sought to clarify causal pathways linking sleep and postpartum depression via longitudinal path modeling. Sleep quality at 6 months postpartum was hypothesized to exacerbate depressive symptoms from 1 month through 1 year postpartum in both mothers and fathers. Within-couple associations between sleep and depression were also tested. METHODS: Data were drawn from a low-income, racially and ethnically diverse sample of 711 couples recruited after the birth of a child. Depressive symptoms were assessed at 1, 6, and 12 months postpartum, and sleep was assessed at 6 months postpartum. RESULTS: For both partnered mothers and fathers and for single mothers, depressive symptoms at 1 month postpartum predicted sleep quality at 6 months, which in turn predicted depressive symptoms at both 6 and 12 months. Results held when infant birth weight, breastfeeding status, and parents' race/ethnicity, poverty, education, and immigration status were controlled. Mothers' and fathers' sleep quality and depressive symptoms were correlated, and maternal sleep quality predicted paternal depressive symptoms both at 6 and at 12 months. CONCLUSIONS: Postpartum sleep difficulties may contribute to a vicious cycle between sleep and the persistence of depression after the birth of a child. Sleep problems may also contribute to the transmission of depression within a couple. Psychoeducation and behavioral treatments to improve sleep may benefit new parents.

OBJECTIVE: Elevated maternal psychosocial stress during pregnancy and accompanying changes in stress hormones may contribute to risk of adverse birth outcomes such as low birth weight and preterm birth. Relatedly, research on fetal programming demonstrates intriguing associations between maternal stress processes during pregnancy and outcomes in offspring that extend into adulthood. The purpose of this study was to test whether hypothalamic-pituitary-adrenal (HPA) patterns in mothers during the period between 2 pregnancies (i.e., the interpregnancy interval) and during the subsequent pregnancy predict infant birth weight, a key birth outcome. METHOD: This study sampled salivary cortisol before and during pregnancy in a diverse community sample of 142 women enrolled in the Community Child Health Network study. RESULTS: Using multilevel modeling, we found that flatter diurnal cortisol slopes in mothers during the interval between one birth and a subsequent pregnancy predicted lower infant birth weight of the subsequent child. This interpregnancy cortisol pattern in mothers also correlated with significantly shorter interpregnancy intervals, such that women with flatter cortisol slopes had more closely spaced pregnancies. After adding demographic covariates of household income, cohabitation with partner, and maternal race to the model, these results were unchanged. For participants who provided both interpregnancy and pregnancy cortisol data (n = 73), we found that interpregnancy cortisol slopes predicted infant birth weight independent of pregnancy cortisol slopes. CONCLUSIONS: These novel findings on interpregnancy HPA axis function and subsequent pregnancy outcomes strongly support life course health approaches and underscore the importance of maternal stress physiology between pregnancies.

Vitamin D deficiency and elevated pro-inflammatory cytokines have each been associated individually with postpartum depression (PPD). African American women are at increased risk for prenatal vitamin D deficiency, inflammation, and prenatal and postpartum depressive symptoms, but biological risk factors for PPD in this population have rarely been tested. This prospective study tested whether low prenatal vitamin D status (serum 25-hydroxyvitamin D, 25[OH]D) predicted PPD symptomatology in pregnant African American women and whether high levels of prenatal inflammatory cytokines interacted with low 25(OH)D in effects on PPD symptoms. Vitamin D status was measured in the first trimester in a sample of 91 African American pregnant women who had a second trimester blood sample assayed for inflammatory markers. Depressive symptoms were assessed at a postpartum visit. An inverse association between prenatal log 25(OH)D and PPD symptomatology approached significance (ß = -0.209, p = 0.058), and interleukin-6 and IL-6/IL-10 ratio significantly moderated the effect. Among women with higher levels of inflammatory markers, lower prenatal log 25(OH)D was associated with significantly higher PPD symptoms (p < 0.05). These preliminary results are intriguing because, if replicable, easy translational opportunities, such as increasing vitamin D status in pregnant women with elevated pro-inflammatory cytokines, may reduce PPD symptoms.

BACKGROUND: Racial and ethnic inequalities in women's health are widely documented, but not for the postpartum period, and few studies examine whether neighborhood, psychosocial, and biological factors explain these gaps in women's health. METHODS: Using prospective longitudinal data collected from 1766 low to middle income women between 2008 and 2012 by the Community Child Health Network (CCHN), we tested the extent to which adjustment for neighborhood, economic, psychological, and medical conditions following a birth explained differences between African American, Latina, and White women in an indicator of physiological dysregulation allostatic load (AL), at one year postpartum as measured by 10 biomarkers: Body Mass Index, Waist Hip Ratio, systolic and diastolic blood pressure, high sensitivity C-reactive protein, Hemoglobin A1c, high-density lipoprotein and cholesterol ratio, and diurnal cortisol. RESULTS: Mean postpartum AL scores were 4.65 for African American, 4.57 for Latina and 3.86 for White women. Unadjusted regression estimates for high AL for African American women (with White as the reference) were 0.80 (SD = 0.11) and 0.53 (SD = 0.15) for Latina women. Adjustment for household poverty, neighborhood, stress, and resilience variables resulted in a reduction of 36% of the excess risk in high AL for African Americans versus Whites and 42% of the excess risk for Latinas compared to Whites. CONCLUSIONS: Racial and ethnic inequalities in AL were accounted for largely by household poverty with additional contributions by psychological, economic, neighbourhood and medical variables. There remained a significant inequality between African American, and Latina women as compared to Whites even after adjustment for this set of variables. Future research into health inequalities among women should include a fuller consideration of the social determinants of health including employment, housing and prepregnancy medical conditions.
