Testing a Conceptual Model of Postpartum Depressive Symptoms in the First Year

Pathways between Risk/Protective Factors and Maternal Postnatal Depressive Symptoms: The ELFE Cohort

OBJECTIVE

The risk factors for postnatal depressive symptoms (PNDS) are numerous, but little is known about the protective factors or the interactions between different exposures. The present study explored the pathways between maternal, infant and parenthood vulnerabilities or risk/protective factors and PNDS at 2 months postpartum (PP) in a large sample of women from the general population.

METHODS

We used data from the French ELFE cohort, a nationally representative cohort of children followed-up from birth. The available information about vulnerabilities or risk/protective factors for PNDS was collected during the maternity ward stay (mother or medical records) and at 2 months PP (mother by phone). PNDS were evaluated with the Edinburgh Postnatal Depression Scale (EPDS) at 2 months. A measurement model was built based on the psychosocial model for PNDS of Milgrom and colleagues using exploratory factor analysis. The Structural Equation Model was used to investigate the pathways between vulnerability, risk/protective factors and PNDS at 2 months PP.

RESULTS

In the study sample (n = 11,583), a lack of a partner's perceived antenatal emotional support, consultation with a mental health specialist before pregnancy, family financial difficulties, prenatal psychological distress and a difficult pregnancy experience were directly associated with the severity of maternal PNDS at 2 months PP, as well as lack of perceived postnatal support. Family financial difficulties and consultation with a mental health specialist before pregnancy were also indirectly associated with the intensity of PNDS through a lack of perceived antenatal emotional support, a difficult pregnancy experience, prenatal psychological distress and a lack of perceived postnatal support. Regarding infant and parenthood characteristics, infant self-regulation difficulties, maternal difficulty in understanding infant crying and infant hospitalisation were directly associated with PNDS severity at 2 months PP, while maternal difficulty in understanding an infant's cries was also indirectly associated with infant self-regulation difficulties.

CONCLUSIONS

Perinatal professional support should begin antenatally and target the couple's prenatal functioning, with particular attention to women presenting a history of psychiatric disorders, especially those of low socioeconomic status. After delivery, addressing infant and parenthood characteristics is also recommended.

Factors That Influence Women's Symptoms of Postpartum Depression After Discharge of Their Preterm Infants From the NICU

OBJECTIVE

To examine resourcefulness, perception of child vulnerability, and stress in relation to symptoms of postpartum depression (PPD) in women after discharge of their preterm infants from the NICU.

DESIGN

Cross-sectional, descriptive, correlational study.

SETTING

An urban NICU follow-up clinic, a pediatric office in the northeastern United States, and an online NICU parent support group.

PARTICIPANTS

Seventy-four women who gave birth to preterm infants who were discharged home from the NICU.

METHODS

The participants completed a demographic data questionnaire, the Resourcefulness Scale, Child Vulnerability Scale, Perceived Stress Scale, and Edinburgh Postnatal Depression Scale. I examined the relationships among these data using correlational analysis and hierarchical multiple linear regression analysis.

RESULTS

Perception of child vulnerability and stress were predictors of symptoms of PPD; these variables accounted for 9% (p = .001) and 18% (p < .001) of the variation in symptoms of PPD, respectively. Although resourcefulness initially predicted PPD, it was no longer significant when controlling for demographic variables in the final regression analysis.

CONCLUSIONS

These results supported previously reported findings on the effects of women's perceptions of their child's vulnerability and stress on symptoms of PPD. However, the findings are not consistent with those of previous research regarding the inverse relationship between resourcefulness and symptoms of PPD. Nurses can implement interventions for women regarding perceptions of child vulnerability and stress to decrease symptoms of PPD after their preterm infant's discharge from the NICU.

Partner relationship satisfaction, partner conflict, and maternal cardio-metabolic health in the year following the birth of a child

Intimate partner relationship quality during the child-bearing years has implications for maternal health. The purpose of this study was to test whether partner satisfaction, partner conflict, and their interaction predicted maternal cardio-metabolic health at 12-months postpartum. Women were recruited in 5 U.S. sites. Partner conflict and satisfaction were measured at 6-months postpartum, and cardio-metabolic indicators (blood pressure, waist-hip ratio, glycosylated hemoglobin, total cholesterol:HDL ratio) were assessed at 6- and 12-months. Cardio-metabolic indices were scored continuously (CM risk) and using clinical risk cutoffs (CM scores). A significant conflict-by-satisfaction interaction emerged for the CM risk, b(SE) = .043 (.016), p = .006, and CM scores, b(SE)= .089 (.028), p = .002, such that when partner satisfaction was low, low partner conflict was associated with poorer postpartum cardio-metabolic health. This is the first study to examine close relationships and cardio-metabolic health during the child-bearing years, an issue warranting further attention.

Postpartum Depressive Symptoms: Risks for Czech and Thai Mothers

Multiple psychosocial risk factors are linked to women's experience of postpartum depressive symptoms worldwide. This study focused on mothers in the Czech Republic (n = 126) and Thailand (n = 161), two countries where little research on mothers' experiences of postpartum depressive symptoms (PPDS) has been conducted. Measures included the Postpartum Social Support Questionnaire, Parenting Sense of Competence Scale, Quality of Relationships Inventory, Dysfunctional Attitude Scale-Form A-17, and Edinburgh Postnatal Depression Scale. Hierarchical linear regression analyses indicated that for Czech mothers, financial concerns, partner conflict, perfectionism, maternal efficacy, and parental support were significantly related to PPDS. For Thai mothers, only partner conflict and perfectionism were significantly related to PPDS. Cultural implications for childbirth educators are discussed in the context of these risk factors.

The Fukushima Nuclear Accident Affected Mothers’ Depression but Not Maternal Confidence

The Fukushima nuclear power plant accident caused widespread radiation contamination. Mothers of young children were at risk of negative emotional and mental health consequences. Using data from 2 independent prefecture-wide surveys of pregnant women, we examined the associations of disaster-related stressors with both maternal self-confidence and depressive symptoms. Two postal surveys were conducted targeting women who registered their pregnancies in Fukushima Prefecture (n = 6686 in 2012 and n = 6423 in 2013). The proportions of mothers with lower self-confidence in child rearing and with depressive symptoms were 53% and 25% in 2012 and 55% and 24% in 2013, respectively. After adjusting for maternal and infant characteristics, evacuation and concern about radiation were significantly associated with depressive symptoms but not lower maternal confidence, although these 2 outcomes were significantly associated. Mothers in Fukushima showed resilience in parenting, whereas their experiences and concerns in the aftermath of nuclear disaster were associated with depressive symptoms.

Social Emotional Factors Increase Risk of Postpartum Depression in Mothers of Preterm Infants

OBJECTIVE

To examine the association of maternal mental health, perceptions of readiness at neonatal intensive care unit (NICU) discharge, and social risk factors with depressive symptoms 1 month postdischarge in mothers of early (<32 weeks), moderate (32-33 weeks), and late (34-36 weeks) preterm infants. A secondary objective was to compare depressive symptoms among mothers in all preterm groups.

STUDY DESIGN

Mothers (n = 734) of preterm infants cared for >5 days in the NICU and participating in a Transition Home Program completed the Fragile Infant Parent Readiness Evaluation prior to discharge for perceptions of NICU staff support, infant well-being, maternal well-being (emotional readiness/competency), and maternal comfort (worry about infant). Mental health history and social risk factors were obtained. At 1 month postdischarge the Edinburgh Postnatal Depression Scale was administered. Group comparisons and logistic regression analyses were run to predict possible depression (Edinburgh Postnatal Depression Scale  ≥10).

RESULTS

Mothers of early, moderate, and late preterm infants reported similar rates of possible depression (20%, 22%, and 18%, respectively) 1 month after NICU discharge. History of mental health disorder, decreased perception of maternal well-being, decreased maternal comfort regarding infant, and decreased perception of family cohesion were associated with possible depression at 1 month postdischarge.

CONCLUSIONS

Mothers with a previous mental health disorder and experiencing negative perceptions of self and infant at NICU discharge were at increased risk for depressive symptomatology 1 month postdischarge regardless of infant gestational age. Comprehensive mental health assessment prior to discharge is essential to identify women at risk and provide appropriate referral.
