Associations of anti-Müllerian hormone levels among women in their mid-30s with menopausal symptoms ~14 years later.

OBJECTIVE: The aim of this study was to examine associations of anti-Müllerian hormone (AMH) levels in gravid women in their mid-30s with menopausal symptoms ~14 years later and age at natural menopause. METHODS: In this prospective analysis, 474 participants in Project Viva, a longitudinal cohort, were enrolled during pregnancy between 1999 and 2002. AMH levels were determined using plasma samples collected 3 years postpartum. Participants completed the Menopause Rating Scale (MRS) and self-reported age at and reason for menopause at the 17 years postpartum visit (Mid-Life Visit). Primary outcomes were individual MRS item responses and total MRS score. To examine associations between AMH levels and menopausal outcomes, we performed linear and logistic regressions, and survival analyses, adjusting for confounding variables. RESULTS: Mean (SD) AMH level was 2.80 (2.74) ng/mL, measured at 38.2 (3.9) years. At the Mid-Life Visit, mean (SD) age was 52.3 (3.9) years and total MRS score was 8.0 (5.7). During follow-up, 50% had experienced natural menopause, and self-reported mean (SD) age at natural menopause was 50.4 (3.6) years. AMH in the lowest tertile (mean [SD]: 0.47 [0.32] ng/mL) was associated with higher odds of moderate to severe vaginal dryness (adjusted odds ratio: 2.58; 95% CI: 1.16 to 5.73), a lower MRS psychological subscale (adjusted ß: -0.71; 95% CI: -1.35 to -0.07), and earlier attainment of natural menopause (adjusted hazards ratio: 7.1; 95% CI: 4.6 to 11.0) compared with AMH in the highest tertile (mean [SD]: 6.01 [2.37] ng/mL). CONCLUSIONS: Lower AMH in the mid-30s was associated with earlier menopause and increased odds of vaginal dryness but fewer psychological symptoms ~14 years later.

Associations of prenatal maternal depressive symptoms with cord blood glucocorticoids and child hair cortisol levels in the project viva and the generation R cohorts: a prospective cohort study.

BACKGROUND: Prior studies have reported conflicting results regarding the association of prenatal maternal depression with offspring cortisol levels. We examined associations of high levels of prenatal depressive symptoms with child cortisol biomarkers. METHODS: In Project Viva (n = 925, Massachusetts USA), mothers reported their depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS) during pregnancy, cord blood glucocorticoids were measured at delivery, and child hair cortisol levels were measured in mid-childhood (mean (SD) age: 7.8 (0.8) years) and early adolescence (mean (SD) age: 13.2 (0.9) years). In the Generation R Study (n = 1644, Rotterdam, The Netherlands), mothers reported depressive symptoms using the Brief Symptom Inventory (BSI) during pregnancy, and child hair cortisol was measured at a mean (SD) age of 6.0 (0.5) years. We used cutoffs of ≥ 13 for the EPDS and > 0.75 for the BSI to indicate high levels of prenatal depressive symptoms. We used multivariable linear regression models adjusted for child sex and age (at outcome), and maternal pre-pregnancy BMI, education, social support from friends/family, pregnancy smoking status, marital status, and household income to assess associations separately in each cohort. We also meta-analyzed childhood hair cortisol results from both cohorts. RESULTS: 8.0% and 5.1% of women respectively experienced high levels of prenatal depressive symptoms in Project Viva and the Generation R Study. We found no associations between high levels of maternal depressive symptoms during pregnancy and child cortisol biomarkers in either cohort. CONCLUSIONS: The present study does not find support for the direct link between high levels of maternal depressive symptoms and offspring cortisol levels.

Maternal Hyperglycemia in Pregnancy and Offspring Internalizing and Externalizing Behaviors.

OBJECTIVE: To examine the associations between exposure to gestational diabetes mellitus (GDM) and maternal glycemic markers during pregnancy and offspring behaviors at 3 and 5 years. We hypothesized that exposure to maternal hyperglycemia would be associated with more behavioral problems in offspring. METHODS: We included 548 mother-child pairs from the prospective pre-birth Gen3G cohort (Canada). Glycemic markers were measured during a 75 g oral glucose tolerance test (OGTT) in the second trimester of pregnancy. Based on OGTT, we classified 59 women (10.8%) as having GDM according to international diagnostic criteria. Mothers reported offspring behavior using the Strengths and Difficulties Questionnaire (SDQ) at 3 and 5 years, and the Child Behavior Checklist (CBCL) at 5 years. We used linear mixed models and multivariate regression to assess the associations between GDM or glycemic markers and children's behavior, adjusted for child sex and age, and maternal demographic factors, body mass index and family history of diabetes. RESULTS: Exposure to GDM was associated with higher SDQ externalizing scores at 3 and 5 years [B = 1.12, 95% CI (0.14, 2.10)] in fully adjusted linear mixed models. These results were supported by the CBCL at 5 years. Higher levels of maternal glucose at 1 h and 2 h during OGTT were associated with greater SDQ externalizing scores. Fasting glucose levels were not associated with child behavior scores. We did not observe associations between glycemic markers and internalizing behaviors. CONCLUSIONS: Exposure to higher levels of maternal glycemia during pregnancy was associated with more externalizing behaviors in children at 3 and 5 years.

What is already known on this subject? Prenatal exposure to gestational diabetes mellitus (GDM) has been linked to a higher risk of long-term consequences in offspring including metabolic problems and cognitive difficulties. However, prior studies examining associations between GDM and behavior in children reported mixed results. What this study adds? We reported associations between exposure to maternal GDM and post-OGTT hyperglycemia during pregnancy and greater levels of externalizing behaviors in children at 3 and 5 years of age. Our results underscore the importance of early detection of behavioral problems in children.

Associations of maternal glucose markers in pregnancy with cord blood glucocorticoids and child hair cortisol levels.

Exposure to maternal hyperglycemia in utero has been associated with adverse metabolic outcomes in offspring. However, few studies have investigated the relationship between maternal hyperglycemia and offspring cortisol levels. We assessed associations of gestational diabetes mellitus (GDM) with cortisol biomarkers in two longitudinal prebirth cohorts: Project Viva included 928 mother-child pairs and Gen3G included 313 mother-child pairs. In Project Viva, GDM was diagnosed in N = 48 (5.2%) women using a two-step procedure (50 g glucose challenge test, if abnormal followed by 100 g oral glucose tolerance test [OGTT]), and in N = 29 (9.3%) women participating in Gen3G using one-step 75 g OGTT. In Project Viva, we measured cord blood glucocorticoids and child hair cortisol levels during mid-childhood (mean (SD) age: 7.8 (0.8) years) and early adolescence (mean (SD) age: 13.2 (0.9) years). In Gen3G, we measured hair cortisol at 5.4 (0.3) years. We used multivariable linear regression to examine associations of GDM with offspring cortisol, adjusting for child age and sex, maternal prepregnancy body mass index, education, and socioeconomic status. We additionally adjusted for child race/ethnicity in the cord blood analyses. In both Project Viva and Gen3G, we observed null associations of GDM and maternal glucose markers in pregnancy with cortisol biomarkers in cord blood at birth (ß = 16.6 nmol/L, 95% CI -60.7, 94.0 in Project Viva) and in hair samples during childhood (ß = -0.56 pg/mg, 95% CI -1.16, 0.04 in Project Viva; ß = 0.09 pg/mg, 95% CI -0.38, 0.57 in Gen3G). Our findings do not support the hypothesis that maternal hyperglycemia is related to hypothalamic-pituitary-adrenal axis activity.

SERPINE1 DNA Methylation Levels Quantified in Blood Cells at Five Years of Age Are Associated with Adiposity and Plasma PAI-1 Levels at Five Years of Age.

Plasminogen activator inhibitor (PAI-1) expression has been associated with a higher risk of development of obesity. DNA methylation (DNAm) is an epigenetic mechanism regulating gene transcription and likely involved in the fetal programming of childhood obesity. Our study aimed to assess the associations between PAI-1 gene (SERPINE1) DNAm, plasma PAI-1 levels, and adiposity at five years of age. We analyzed DNAm and anthropometric data from 146 girls and 177 boys from the Gen3G prospective birth cohort. We assessed adiposity using BMI z-scores, waist circumference, total skinfolds, and percentages of total, android, and trunk fat measured by dual-energy radiography (DXA). We estimated blood cell DNAm levels at 15 CpG sites within SERPINE1 using the methylationEPIC array. After correction for multiple testing, we found that lower DNAm in SERPINE1 intron 3 (cg11353706) was associated with greater adiposity levels in girls (waist circumference: r = −0.258, p = 0.002; skinfolds: r = −0.212, p = 0. 013; android fat: r = −0.215, p = 0.015; BMI z-score: r = −0.278, p < 0.001) and that lower DNAm in the SERPINE1 promoter (cg19722814) was associated with higher plasma PAI-1 levels in boys (r = −0.178, p = 0.021). Our study suggests that DNAm levels at the SERPINE1 gene locus are negatively correlated with adiposity, but not with plasma PAI-1 levels, in young girls only.

Longitudinal associations of psychosocial stressors with menopausal symptoms and well-being among women in midlife.

OBJECTIVE: We examined longitudinal associations of psychosocial stressors with menopausal symptoms and well-being of women in midlife in a longitudinal cohort. METHODS: This study is based on 682 women from Project Viva, a prospective cohort enrolled in 1999 to 2002 during pregnancy (median age = 33.3 y) and followed for almost two decades. In pregnancy, women self-reported psychosocial stressors (history of physical and sexual abuse and financial instability, from childhood to the current pregnancy). In 2017 to 2021 (median age, 51.6 y), they reported their menopausal symptoms (0-44 point scale) and well-being (general health [good/fair/poor vs excellent/very good], generalized anxiety symptoms, and depressive symptoms [both-more than minimal levels vs none/minimal]). We performed multivariable and logistic regression models to examine associations of psychosocial stressors with outcomes, adjusting for covariates. RESULTS: History of physical abuse (reported by 37.3%) was associated with worse menopausal symptoms in the somatovegetative (odds ratio [OR], 0.46 points; 95% confidence interval [CI], 0.04-0.87 points) and psychological (OR, 0.52 points; 95% CI, 0.07-0.97 points) domains and with worse general health (OR, 1.73; 95% CI, 1.17-2.55) and greater depressive symptoms (OR, 1.74; 95% CI, 1.05-2.87). History of sexual abuse (7.7%) was associated with worse menopausal symptoms (OR, 2.81 points; 95% CI, 1.05-4.56) and worse general health (OR, 2.04; 95% CI, 1.04-4.03) but not with depressive symptoms. History of financial instability (10.8%) was associated with worse menopausal symptoms (1.92 points; 0.49 to 3.34), worse general health (OR, 2.16; 95% CI, 1.24-3.75), and greater depressive symptoms (OR, 2.68; 95% CI, 1.44-4.98). We observed no association between psychosocial stressors and generalized anxiety symptoms assessed at midlife. CONCLUSIONS: Psychosocial stressors were associated with worse menopausal symptoms and well-being decades after initial report.

Trajectories of depressive symptoms among mothers of preterm and full-term infants in a national sample.

To examine postpartum depressive symptom trajectories from birth to age 5 and their risk factors in a national sample of mothers of preterm and full-term infants. The racially and ethnically diverse sample comprised 11,320 maternal participants (Mage = 29; SD = 5.9) in the Environmental influences on Child Health Outcomes (ECHO) Program in the USA with data on newborn gestational age at birth (≥ 22 weeks) and maternal depression symptoms during the first 5 years following childbirth. Growth mixture models determined the number and trajectory of postpartum depression classes among women in the preterm and full-term groups, and we examined predictors of class membership. Five trajectories described depressive symptoms for both groups; however, notable differences were observed. One in 5 mothers of preterm infants developed clinically relevant depressive symptoms over time compared with 1 in 10 mothers of full-term infants. Among women who delivered preterm compared with those who delivered full-term, symptoms were more likely to increase over time and become severe when offspring were older. Distinct subgroups describe mothers' depressive symptom trajectories through 5 years following childbirth. Mild to moderate depressive symptoms may onset or persist for many women beyond the initial postpartum period regardless of newborn gestational age at birth. For women with preterm infants, initially mild symptoms may increase to high levels of severity during the preschool and toddler years.

Associations of maternal insulin resistance during pregnancy and offspring inflammation at birth and at 5 years of age: A prospective study in the Gen3G cohort.

BACKGROUND: Maternal insulin resistance is associated with greater maternal inflammation during pregnancy, but its relation to inflammation in offspring remains unclear. The goal of this study was to assess the relationship of gestational insulin resistance and other glycemic markers with offspring inflammation at birth and at 5 years of age. METHODS: We included 653 mother-child pairs from the prospective pre-birth Gen3G cohort. We examined maternal insulin and glucose levels measured during the second trimester of pregnancy, from which we derived the homeostatic model of assessment of insulin resistance (HOMA-IR) and the Matsuda index. We assessed offspring inflammation at birth and at 5 years of age by measuring plasma tumor necrosis factor-α (TNFα) concentrations. We conducted multivariable regression models to evaluate associations of each insulin and glucose marker with offspring inflammation adjusting for confounding variables. RESULTS: Higher levels of fasting insulin were associated with lower TNFα levels at birth (-0.78, 95% CI [-1.45, -0.11]), in the fully adjusted model. We observed similar associations with the HOMA-IR and opposite direction with the Matsuda index. We did not find persistence of the association between maternal fasting insulin and offspring TNFα at 5 years of age. CONCLUSIONS: Greater maternal insulin resistance during pregnancy was associated with lower cord blood TNFα levels in newborns. The mechanisms by which maternal insulin resistance may promote lower inflammatory levels in newborns are not fully understood and more research is needed to deepen our understanding of these mechanisms.

Maternal glucose tolerance in pregnancy and child cognitive and behavioural problems in early and mid-childhood.

BACKGROUND: Maternal abnormal glucose tolerance during pregnancy may adversely affect offspring cognition and behaviour, but few prospective studies investigated this association at multiple points throughout childhood. OBJECTIVES: We hypothesised that maternal abnormal glucose tolerance is associated with child cognitive and behavioural outcomes in early and mid-childhood. METHODS: We examined the associations of maternal abnormal glucose tolerance at 26-28 weeks of pregnancy with offspring cognitive and behavioural scores in 1421 children in the Project Viva pre-birth cohort. In early (mean 3.3 years) and mid-childhood (mean 7.9 years), we measured child cognition using validated instruments, the Kaufman Brief Intelligence Test, Wide Range Assessment of Memory and Learning, and the Wide Range Assessment of Visual Motor Abilities (WRAVMA); we assessed parent- and teacher-rated behavioural outcomes with the Strengths and Difficulties Questionnaire and the Behavioural Rating Inventory of Executive Function. We used linear regression models adjusted for potential confounders (maternal race/ethnicity, pre-pregnancy BMI, intelligence, age, parity, smoking status, education, and household income at enrolment, in addition to child's sex and age at assessment). RESULTS: Of 1421 mothers, 69 (4.9%) had gestational diabetes mellitus, 43 (3.0%) impaired glucose tolerance, 122 (8.6%) isolated hyperglycaemia, and 1187 (83.5%) normal glucose tolerance. Offspring born to women with gestational diabetes mellitus had lower total WRAVMA scores (-3.09 points; 95% CI -6.12, -0.05) in early childhood compared with offspring of women with normal glucose tolerance. None of the abnormal glucose tolerance categories during pregnancy were associated with any of the cognitive outcomes (verbal, non-verbal, and visual motor scores) or behavioural measures in mid-childhood. CONCLUSIONS: Children born to mothers who had gestational diabetes mellitus had slightly lower scores on one cognitive test in early childhood. We found no evidence to support that maternal abnormal glucose tolerance was associated with cognitive or behavioural development in mid-childhood.

History of perinatal loss: A study of psychological outcomes in mothers and fathers after subsequent healthy birth.

BACKGROUND: The loss of an expected child is a psychologically difficult and potentially traumatic life event. While most women will become pregnant again within a year following the loss, data are limited regarding the mental health of parents with a history of perinatal loss, especially in the period following the birth of a subsequent healthy child. This study, therefore, investigated the relation between perinatal loss and mothers' and fathers' psychological symptoms and parenting stress 6-months after the birth of a healthy child. METHODS: A community sample of 92 mother-father dyads living in a Canadian city and having a 6-month-old biological infant were asked to complete questionnaires measuring their history of perinatal losses (55 parents reporting at least one loss) and their psychological symptoms and parenting stress. RESULTS: Mothers and fathers who have experienced a perinatal loss reported more psychological symptoms and parenting stress. Mothers were more likely to report psychological symptoms and parenting stress compared to fathers, but the magnitude of the relation between perinatal losses and psychological outcomes were comparable for mothers and fathers. LIMITATIONS: Limitations of the study include the use of a small community sample with low generalizability and low levels of psychological symptoms and stress. CONCLUSIONS: The results suggest that the experience of a perinatal loss might have negative consequences on the psychological wellbeing of parents even after the birth of a healthy child.

Associations of Early Parental Concerns and Feeding Behaviors with Child's Diet Quality through Mid-Childhood.

Parental feeding practices have been associated with children's dietary intakes, yet the directionality of these associations remains unclear. Among 1172 mother-child pairs from Project Viva, we aimed to examine associations of parental concerns and feeding behaviors at 2 years (behaviors dichotomized as yes vs. no), with diet quality (Youth Healthy Eating Index; YHEI) in early (mean 3.2, SD 0.3 years; n = 1076) and mid-childhood (mean 7.8, SD 0.7 years; n = 993). We used multivariable linear regression models adjusted for sociodemographic characteristics, parental body mass index (BMI), maternal diet quality in pregnancy, and child's BMI z-score and diet quality at 2 years. Early parental concerns about their child becoming overweight (15%) was associated with lower YHEI (ß -1.54 points; 95%CI -2.75, -0.33; fully adjusted model) in early childhood. Early parental concerns about their child becoming underweight (7%) was associated with lower YHEI (-2.19 points; -4.31, -0.07) in early childhood, but the association was attenuated after adjustment for child's BMI z-score and diet quality at 2 years. We did not find associations of parental restrictive feeding (8%) and parental pressure to eat (47%) with child's YHEI through mid-childhood. In conclusion, we found no evidence that early parental concerns and feeding behaviors independently contribute to child's diet quality through childhood.

Trajectories of Overprotective Parenting and Hyperactivity-Impulsivity and Inattention Among Moderate-Late Preterm Children: A Population-Based Study.

Parents of preterm children are more likely to adopt non-optimal parenting behaviors than parents of full-term (FT) children. However, there is a lack of studies on parents of children born moderate to late preterm (MLP; 32-36 gestational weeks). In this study, we aimed to examine: (1) the association between MLP birth status and the trajectory of parental overprotection throughout preschool years, and (2) the role of parental overprotection, MLP birth status, and their interaction in the prediction of the trajectories of hyperactivity-impulsivity and inattention throughout childhood. Data comes from a Canadian representative population-based cohort including 2028 FT, 100 MLP children, and their parents. Overprotective parenting was measured when children were 5, 17, and 29 months old. Hyperactivity-impulsivity and inattention symptoms were measured repeatedly from 4 to 8 years of age. Trajectories of parents' overprotectiveness and children's hyperactivity-impulsivity and inattention were modeled. MLP birth status was associated with an increase in parental overprotectiveness across the preschool period. MLP birth status and parental overprotection were both found to be associated with higher levels of hyperactivity-impulsivity symptoms across childhood. No interaction was found between birth status and parental overprotection. The results suggest that parents of MLP children become more overprotective across time compared to parents of FT children and that children born MLP and/or exposed to higher levels of parental overprotection demonstrated higher levels of hyperactivity-impulsivity symptoms across childhood.

Trajectories of behavioral problems among moderate-late preterm children from 4 to 10 years: A prospective population-based study.

BACKGROUND: A growing body of research suggests that moderate to late preterm children (MLP; 32 through 36 weeks of gestation) may have higher rates of behavioral problems than full-term (FT) children. However, few studies have followed MLP children over time using a longitudinal design with repeated measures. AIM: The current prospective longitudinal study aims to examine the relation between MLP birth and trajectories of behavioral problems among children from ages 4 to 10 years. STUDY DESIGN AND SUBJECTS: The data comes from a Canadian representative population-based study including 1841 FT children and 89 MLP children. OUTCOME MEASURES: Four categories of behavioral problems were measured repeatedly from 4 to 10 years using parent and teacher reports: hyperactivity-impulsivity, inattention, anxiety-depression, and aggression. Developmental trajectories were modeled using Mplus. RESULTS: After accounting for child sex and family income, a significant and persistent association was found between MLP birth and the developmental trajectory of hyperactivity-impulsivity reported by the parent. No relation was found regarding trajectories of inattention, anxiety-depression, and aggression problems. CONCLUSIONS: According to parent reports, MLP children were more likely to exhibit hyperactive and impulsive behaviors compared to FT peers during early childhood. However, the relation between MLP birth and the trajectory of parent-reported hyperactivity-impulsivity was small and was not confirmed by teacher evaluation. Moreover, MLP children did not differ from FT children regarding the overall trajectory of inattention, anxiety-depression, and aggression problems.

Women's perceived social support: associations with postpartum weight retention, health behaviors and depressive symptoms.

BACKGROUND: Social support may promote healthful behaviors that prevent excess weight at critical periods in women's life. Our objective was to investigate associations of social support at 6 months postpartum with women's health behaviors that have previously been shown to predict weight retention at 1 year postpartum. METHODS: At 6 months postpartum in Project Viva, a pre-birth prospective cohort in Massachusetts, women reported social support using the Turner Support Scale, depressive symptoms using the Edinburgh Postnatal Depression Scale, diet using PrimeScreen, average number of hours walking, light/moderate and vigorous physical activity, television viewing, and sleeping each day. RESULTS: Among 1356 women, greater partner support was associated with higher levels of walking (OR 1.36, 95% CI [1.01, 1.82]) and intake of fiber (OR 1.43, 95% CI [1.06, 1.91]) and lower intake of trans-fat (OR 1.49, 95% CI [1.11, 2.01]). Support from family/friends was marginally related to healthful levels of light/moderate physical activity (OR 1.26, 95% CI [0.96, 1.65]) and television viewing (OR 1.29, 95% CI [0.99, 1.69]). Both sources of support were strongly associated with lower odds of incident depression (OR 0.33, 95% CI [0.20, 0.55] and OR 0.49, 95% CI [0.30, 0.79], respectively). We did not find associations with vigorous physical activity or sleep duration. CONCLUSIONS: Social support is important to the physical and mental health of new mothers and may promote behaviors that limit postpartum weight retention.

Prenatal maternal antidepressants, anxiety, and depression and offspring DNA methylation: epigenome-wide associations at birth and persistence into early childhood.

BACKGROUND: Maternal mood disorders and their treatment during pregnancy may have effects on the offspring epigenome. We aim to evaluate associations of maternal prenatal antidepressant use, anxiety, and depression with cord blood DNA methylation across the genome at birth and test for persistence of associations in early and mid-childhood blood DNA. METHODS: A discovery phase was conducted in Project Viva, a prospective pre-birth cohort study with external replication in an independent cohort, the Generation R Study. In Project Viva, pregnant women were recruited between 1999 and 2002 in Eastern Massachusetts, USA. In the Generation R Study, pregnant women were recruited between 2002 and 2006 in Rotterdam, the Netherlands. In Project Viva, 479 infants had data on maternal antidepressant use, anxiety, depression, and cord blood DNA methylation, 120 children had DNA methylation measured in early childhood (~ 3 years), and 460 in mid-childhood (~ 7 years). In the Generation R Study, 999 infants had data on maternal antidepressants and cord blood DNA methylation. The prenatal antidepressant prescription was obtained from medical records. At-mid pregnancy, symptoms of anxiety and depression were assessed with the Pregnancy-Related Anxiety Scale and the Edinburgh Postnatal Depression Scale in Project Viva and with the Brief Symptom Inventory in the Generation R Study. Genome-wide DNA methylation was measured using the Infinium HumanMethylation450 BeadChip in both cohorts. RESULTS: In Project Viva, 2.9% (14/479) pregnant women were prescribed antidepressants, 9.0% (40/445) experienced high pregnancy-related anxiety, and 8.2% (33/402) reported symptoms consistent with depression. Newborns exposed to antidepressants in pregnancy had 7.2% lower DNA methylation (95% CI, - 10.4, - 4.1; P = 1.03 × 10-8) at cg22159528 located in the gene body of ZNF575, and this association replicated in the Generation R Study (ß = - 2.5%; 95% CI - 4.2, - 0.7; P = 0.006). In Project Viva, the association persisted in early (ß = - 6.2%; 95% CI - 10.7, - 1.6) but not mid-childhood. We observed cohort-specific associations for maternal anxiety and depression in Project Viva that did not replicate. CONCLUSIONS: The ZNF575 gene is involved in transcriptional regulation but specific functions are largely unknown. Given the widespread use of antidepressants in pregnancy, as well as the effects of exposure to anxiety and depression, implications of potential fetal epigenetic programming by these risk factors and their impacts on development merit further investigation.

Associations of Prenatal and Postnatal Maternal Depressive Symptoms with Offspring Cognition and Behavior in Mid-Childhood: A Prospective Cohort Study.

Exposure to maternal depressive symptoms in the peri-pregnancy periods may be associated with poorer child development, but research is often limited to only maternal assessments of behavior and cognition. This study investigates the specific periods of prenatal and postnatal exposure to maternal depressive symptoms in association with child development using reports from teachers and mothers. This study is based on 1225 mother⁻child pairs from Project Viva, a prospective pre-birth cohort study. Mothers reported depressive symptoms on the Edinburgh Postpartum Depression Scale (EPDS) in mid-pregnancy as well as at 6 months and 12 months postpartum. Teachers and mothers reported child executive functions using the Behavioral Rating Inventory of Executive Function (BRIEF) and behavior using the Strengths and Difficulties Questionnaire (SDQ). Children completed the Kaufman Brief Intelligence Test (KBIT-2), the Wide Range Assessment of Visual Motor Abilities (WRAVMA), and the Visual Memory Index of the Wide Range Assessment of Memory and Learning (WRAML). We used multivariable linear regression models to examine associations of prenatal and postpartum depressive symptoms with outcomes. Many of the crude associations observed were attenuated after adjusting for demographic factors and maternal IQ, yet some remained significant. For example, high prenatal maternal depressive symptoms were associated with poorer scores on the BRIEF Behavior Regulation Index and some SDQ scales based on reports from teachers and mothers. High prenatal maternal depressive symptoms were associated with poorer behavioral development. Postpartum symptoms did not show strong associations with outcomes once we adjusted for the prenatal period.
