Within-dyad bidirectional relations among maternal depressive symptoms and child behavior problems from infancy through preschool

Although dyadic theory focuses on the impact of a mother’s mental health on her own child and the impact of a child’s mental health on their own mother, commonly used statistical approaches are incapable of distinguishing the desired within-dyad processes from between-dyad effects. Using autoregressive latent trajectory modeling with structured residuals, the current study evaluated within-dyad, bidirectional associations between maternal depressive symptoms and child behavior problems from child age 1–4.5 years among a sample of low-income, Mexican American women (N = 322, Mage = 27.8) and their children. Women reported on maternal depressive symptoms and child behavior problems during laboratory visits at child age 1, 1.5, 2, 3, and 4.5 years. Results provide novel evidence of child-driven bidirectional association between maternal depressive symptoms and child behavior problems at the within-dyad level as early as child age 1 year and within-person stability in child behavior problems emerging early in life.

A pilot study of multilevel analysis of BDNF in paternal and maternal perinatal depression

Depression in the perinatal period is common in mothers worldwide. Emerging research indicates that fathers are also at risk of developing perinatal depression. However, knowledge regarding biological risk factors and pathophysiological mechanisms of perinatal depression is still scarce, particularly in fathers. It has been suggested that the neurotrophin BDNF may play a role in maternal perinatal depression; however, there is currently no data regarding paternal perinatal depression. For this pilot study, 81 expecting parents were recruited and assessed at several time points. We screened for depression using EPDS and MADRS, investigated several psychosocial variables, and took blood samples for BDNF val66met genotyping, epigenetic, and protein analysis. Between pregnancy and 12 months postpartum (pp), we found that 3.7 to 15.7% of fathers screened positive for depression, and 9.6 to 24% of mothers, with at least a twofold increased prevalence in both parents using MADRS compared with EPDS. We also identified several psychosocial factors associated with perinatal depression in both parents. The data revealed a trend that lower BDNF levels correlated with maternal depressive symptoms at 3 months pp. In the fathers, no significant correlations between BDNF and perinatal depression were found. Pregnant women demonstrated lower BDNF methylation and BDNF protein expression compared with men; however, these were found to increase postpartum. Lastly, we identified correlations between depressive symptoms and psychosocial/neurobiological factors. The data suggest that BDNF may play a role in maternal perinatal depression, but not paternal.

Family dynamics. An exploration of parental sensitivity and depressive symptoms among mothers and fathers of toddlers

In studies of maternal sensitivity, the influence of mothers’ depressive symptomatology has been consistently highlighted. Additionally, the relevance of both maternal and paternal sensitive responses to children’s development has been recognized. However, literature regarding the dynamics of the mother-father-toddler triad is scarce. This is particularly true when understanding how parental sensitivity may be bidirectionally shaped by both parents’ (i.e., mothers’ and fathers’ depressive symptomatology) and children’s characteristics (i.e., age). Hence, the present study aims to describe and analyse the associations between parental depression, paternal sensitivity and children’s socioemotional difficulties and age with mothers’ sensitive responses to highlight the appropriateness of considering fathers’ depressive symptoms and sensitivity to better understand the impact of maternal depressive symptomatology on mothers’ sensitivity. The participants included 80 Chilean mother-father-child triads in which all children were between 1 and 3 years of age and presented some degree of socioemotional difficulty. The results reveal no differences in maternal and paternal sensitivity or higher depressive symptomatology in mothers than in fathers. Additionally, while mothers’ depression was significantly associated with their sensitivity, this was not the case for fathers. Paternal depressive symptomatology was associated with the mother’s depression. Finally, paternal sensitivity emerged as a mediator between maternal depressive symptoms and sensitivity. This result calls attention to the use of paternal variables to understand how maternal depression impacts mothers’ sensitivity and to thus develop appropriate interventions that expand the scope of such impacts from the dyad to the triad.

The Impact of Maternal Depression and Parent–Child Interactions on Risk of Parasitic Infections in Early Childhood: A Prospective Cohort in Benin

Objectives Maternal depression occurs in 13–20% of women from low-income countries, which is associated with negative child health outcomes, including diarrheal disease. However, few studies have investigated its impact on child risk of infectious disease. We studied the impacts of maternal depressive symptoms and parent–child interactions, independently, on the risk of Plasmodium falciparum malaria and soil-transmitted helminth infection in Beninese children. Methods Our population included mothers and children enrolled in a clinical trial during pregnancy (MiPPAD) in Benin. The Edinburgh Postnatal Depression Scale (EPDS) assessed maternal depressive symptoms and the home observation measurement of the environment (HOME) assessed parent–child interactions. Blood and stool sample analyses diagnosed child malaria and helminth infection at 12, 18, and 24 months. Negative binomial and Poisson regression models with robust variance tested associations. Results Of the 302 mother–child pairs, 39 (12.9%) mothers had depressive symptoms. Median number of malaria episodes per child was 3 (0–14) and 29.1% children had at least one helminth infection. Higher EPDS scores were associated with lower HOME scores; relative risk (RR) 0.97 (95% confidence interval (CI) 0.95, 0.99), particularly with lower acceptance, involvement, and variety subscales; RR 0.92 (95% CI 0.85, 0.99), RR 0.82 (95% CI 0.77, 0.88), RR 0.93 (95% CI 0.88, 0.99), respectively. However, neither exposure was associated with risk of parasitic infection in children. Conclusions for Practice Maternal depressive symptoms are associated with poor parent–child interactions, particularly acceptance of behavior, involvement with children, and variety of interactions, but these exposures do not independently impact risk of parasitic infection in children.

Maternal Prenatal Somatization, Postnatal Depression, and Offspring Temperament During the COVID-19 Pandemic

Background. Researchers have begun to examine the psychological toll of the ongoing global COVID-19 pandemic. Data are now emerging indicating that there may be long-term adverse effects of the pandemic on new mothers and on children born during this period. Methods. In a longitudinal study of maternal mental health and child emotional development during the pandemic, we conducted online assessments of a cohort of women at two time points: when they were pregnant at the beginning of the surge of the pandemic in the United States (N=725), and approximately one year postpartum (N=296), examining prenatal and postnatal maternal mental health symptoms and infant temperament. Results. Prenatal maternal symptoms of somatization, the number of people in the household with COVID-19 symptoms, and postnatal maternal depressive symptoms all were positively associated with infant negative affect. Further, postnatal maternal depressive symptoms mediated the relation between prenatal maternal symptoms of somatization and infant negative affect. Conclusions. These findings have important implications for our understanding of the persistence of mental health symptoms in potentially vulnerable groups and of the emotional development of children who were in utero during the COVID-19 pandemic.
