The Efficacy of Provider-Based Prenatal Interventions to Reduce Maternal Stress: A Systematic Review

PURPOSE

Exposure to stress during the prenatal period is often associated with adverse maternal and neonatal health outcomes and is increasing in prevalence in the United States. Health care providers play a crucial role in addressing and mitigating this stress, but there is a lack of consensus in effective interventions. This review evaluates the effectiveness of prenatal provider-based interventions that reduce stress for pregnant people, especially those who are disproportionately affected by stress.

METHODS

A search of relevant English-language literature was conducted using PubMed, CINAHL, Web of Science, Embase, and PyscInfo. Inclusion criteria were 1) the target population was pregnant people, 2) the intervention was delivered within the U.S. health care system, and 3) the study intervention had the goal of reducing stress (stress-reducing intervention).

RESULTS

A total of 3,562 records were identified in the search and 23 were included in analysis. The four identified categories for provider-led stress-reducing prenatal interventions included in the review are 1) skills-building, 2) mindfulness, 3) behavioral therapy, and 4) group support. Findings suggest an increased overall likelihood of mood and maternal stress improvement among pregnant people who complete provider-based stress-reducing interventions, especially group-based therapies that integrated resource allocation, skills-building, mindfulness, and/or behavioral therapy into an intersectional program. However, the efficacy of each type of intervention varies by category and type of maternal stress targeted.

CONCLUSIONS

Although few studies demonstrated a significant reduction in stress for pregnant people, this review highlights the critical need for increased research and attention to stress-reducing interventions in the prenatal period, especially as it pertains to minoritized populations.

The contribution of group prenatal care to maternal psychological health outcomes: A systematic review

PROBLEM

Poor mental health remains a significant cause of morbidity for childbearing women globally.

BACKGROUND

Group care has been shown to be effective in reducing select clinical outcomes, e.g., the rate of preterm birth, but less is known about the effect of Group Prenatal Care (GPC) on mental health outcomes of stress, depression and anxiety in pregnant women.

AIM

To conduct a systematic review of the current evidence of the effect of group pregnancy care on mental health and wellbeing outcomes (i.e., stress, depression and/or anxiety) in childbearing women.

METHODS

A comprehensive search of published studies in Medline, PsychInfo, CINAHL, ProQuest databases, ClinicalTrials.gov and Google Scholar. Databases were systematically searched without publication period restriction until Feb 2020. Inclusion criteria were randomized controlled trials (including quasi-experimental) and observational studies comparing group care with standard pregnancy care. Included were studies published in English, whose primary outcome measures were stress, depression and/or anxiety.

RESULTS

Nine studies met the inclusion criteria, five randomized controlled trials and four observational studies, involving 1585 women (39%) in GPC and 2456 women (61%) in standard (individual) pregnancy care. Although evidence is limited, where targeted education was integrated into the group pregnancy care model, significant reductions in depressive symptoms were observed. In addition, secondary analysis across several studies identified a subset of GPC women, i.e., higher risk for psychological symptoms, who reported a decrease in their depression, stress and anxiety symptoms, postpartum. Due to the diversity of group care structure and content and the lack of outcomes measures universally reported, a comprehensive meta-analysis could not be performed.

CONCLUSION

The evidence suggests improvements in some markers of psychological health outcomes with group pregnancy care. Future research should involve larger well-designed studies encompassing cross-population data using a validated scale that is comparable across diverse childbearing populations and clinical settings to better understand the impact of group pregnancy care.

Prenatal maternal stress and risk of neurodevelopmental disorders in the offspring: a systematic review and meta-analysis

PURPOSE

Exposure to prenatal stress has been reported to affect the risk of adverse neurodevelopmental outcomes in the offspring; however, there is currently no clear consensus. The aim of this systematic review and meta-analysis was to examine the existing literature on the association between prenatal stress and autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) in the offspring.

METHODS

Based on a registered protocol, we searched several electronic databases for articles in accordance with a detailed search strategy. We performed this study following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA).

RESULTS

Prenatal stress was significantly associated with an increased risk of both ASD (pooled OR 1.64 [95% CI 1.15-2.34]; I² = 90%; 15 articles) and ADHD (pooled OR 1.72 [95% CI 1.27-2.34]; I² = 85%; 12 articles).

CONCLUSIONS

This study suggests that prenatal stress may be associated with ASD and ADHD; however, several limitations in the reviewed literature should be noted including significant heterogeneity and there is a need for carefully controlled future studies in this area.
