Maternal and child health programs are essential in supporting families, particularly those facing socioeconomic challenges. Home-visiting programs have been lauded for their positive impacts across various domains, including parenting skills, child development, and family economic stability.

However, there is a notable scarcity of research focusing specifically on maternal and infant health outcomes during the antenatal and newborn periods. Addressing this gap, a study titled "Randomized Controlled Trial of Doula-Home-Visiting Services: Impact on Maternal and Infant Health" by Sydney L. Hans, Renee C. Edwards, and Yudong Zhang delves into the efficacy of integrating community doulas into established home-visiting models in Illinois.

Study Overview

Conducted between 2011 and 2015, this randomized controlled trial (RCT) aimed to evaluate whether the incorporation of doulas into home-visiting services could lead to improved health outcomes for both mothers and their infants. The study involved 312 young, pregnant women with an average age of 18.4 years, drawn from four high-poverty communities in Illinois. The demographic breakdown was 45% African American, 38% Latina, 8% white, and 9% multiracial or other ethnicities. Participants were randomly assigned to one of two groups:

1. Intervention Group: Received doula-home-visiting services.
2. Control Group: Received standard case management services (providing information and referrals to community resources).

Intervention Details

The doula-home-visiting model was innovative, integrating community doulas into the traditional home-visiting framework. Here's a closer look at the specific interventions:

• Community Doulas: These doulas were trained in pregnancy health, childbirth preparation, labor support, lactation counseling, and newborn care. Their roles extended beyond traditional support, including:
  • Home-Based Education: Providing education and support during the latter half of pregnancy and the first six weeks postpartum.
  • Labor Support: Accompanying mothers to the hospital during labor to offer physical comfort, emotional support, and advocacy.
  • Postpartum Assistance: Assisting with breastfeeding, bonding, and offering strategies for soothing infants.
  • Prenatal Classes: Conducting childbirth preparation classes at program sites.
• Home Visitors: Also known as Family Support Workers or Parent Educators, they focused on:
  • Mother-Infant Relationship: Enhancing the bond between mother and child.
  • Child Development and Safety: Educating mothers on child development milestones and safety practices.
  • Educational and Work Planning: Assisting mothers in planning for education and employment.
  • Basic Needs Assessment: Ensuring that families' basic needs related to health, housing, food, and childcare were met.

In the intervention group, mothers were visited weekly by either a doula, a home visitor, or both, with doulas taking a more intensive role during pregnancy and the initial postpartum period.

The control group received standard case management services, which included:

• Information Provision: Mothers were given information about available case management services in their communities.
• Referral to Services: Case managers assessed and referred mothers to necessary services related to health, housing, food, employment, education, and childcare.
• Minimal Contact: It was expected that mothers would have at least two meetings with case managers—one during pregnancy and another post-birth.

Methodology

Participants underwent a structured enrollment process, which included:

• Eligibility Criteria: Women under 26 years old, less than 34 weeks gestation, residing in the program's geographic area, planning to stay in the area, and meeting specific sociodemographic risk factors.
• Exclusions: Pregnant women under 14, those involved with child welfare or juvenile justice systems, or with significant cognitive impairments were excluded for ethical reasons but were still offered home-visiting services.
• Randomization: Conducted via sealed opaque envelopes to ensure unbiased group assignments.

Data collection involved interviews conducted:

• During Pregnancy
• At 3 Weeks Postpartum
• At 3 Months Postpartum

These interviews captured a range of outcomes, including birth outcomes, maternal health, infant health, breastfeeding practices, sleep safety, and car-seat utilization.

Key Findings

The study yielded several significant findings, highlighting both successes and areas needing further attention:

1. Childbirth Preparation and Labor Support:
   • Class Attendance: Mothers in the intervention group were significantly more likely to attend childbirth-preparation classes (50% vs. 10%, Odds Ratio [OR] = 9.82, p < .01). Odds Ratio indicates that intervention-group mothers were nearly 10 times more likely to attend classes compared to the control group. This indicates that the support from doulas effectively encouraged participation in preparatory education.
   • Pain Management: Intervention-group mothers were less likely to use epidural or other pain medications during labor (72% vs. 83%, OR = 0.49, p < .01). This suggests that the emotional and physical support provided by doulas may have contributed to a reduced reliance on pharmacologic pain relief.
2. Breastfeeding Initiation:
   • Initial Rates: There was a higher rate of breastfeeding initiation among intervention-group mothers (81% vs. 74%, OR = 1.72, p < .05).
   • Sustainability Issue: Despite the initial increase, the impact on breastfeeding was not sustained at three months postpartum, with no significant differences observed between groups.
3. Infant Care Practices:
   • Safe Sleep Practices: Intervention-group mothers were more likely to always place their infants on their backs to sleep at three weeks (70% vs. 61%, OR = 1.64, p < .05).
   • Car-Seat Utilization: There was a notable increase in the use of car seats among intervention-group mothers at three weeks postpartum (97% vs. 93%, OR = 3.16, p < .05).
   • Own Bed Usage: A trend (though not statistically significant) indicated that infants in the intervention group were more likely to have their own beds at three weeks (52.9% vs. 44.4%, OR = 1.44, p = .07).
4. Maternal and Infant Health Outcomes:
   • No Significant Impact: The intervention did not significantly affect Caesarean delivery rates, birthweight, prematurity, or postpartum depressive symptoms.
   • Infant Health: There were no significant differences in preterm births, low birthweight, NICU admissions, or infant re-hospitalizations between the two groups.

Implications for Practice

The study underscores the value of integrating community doulas into home-visiting programs, particularly in enhancing specific infant-care behaviors and aspects of maternal health during the immediate postpartum period. Key implications include:

• Enhanced Education and Support: The significant increase in childbirth class attendance and reduced pain medication usage highlights the effectiveness of comprehensive support models.
• Promoting Safe Infant Care: Improved safe sleep practices and car-seat utilization can lead to long-term health benefits for infants, potentially reducing risks associated with SIDS and car accidents.
• Breastfeeding Initiation vs. Sustainability: While initial breastfeeding rates improved, the lack of sustained impact suggests the need for ongoing support mechanisms to maintain breastfeeding practices.

Limitations and Future Research

While the study presents compelling findings, it is important to consider its limitations:

• Sample Scope: The study was limited to four programs within Illinois, potentially restricting the generalizability of the results to other regions or populations.
• Exclusion of High-Risk Adolescents: Adolescents at the highest risk were excluded, meaning the findings may not apply to this particularly vulnerable group.
• Self-Reported Data: Reliance on maternal self-reporting may introduce biases or inaccuracies, especially concerning sensitive health outcomes.
• Combined Intervention Effect: Since mothers received both doula and home visitor services, the independent contributions of each were not isolated.
• Power to Detect Rare Outcomes: The study was not sufficiently powered to detect less common health outcomes like infant mortality.

Future research should aim to:

• Broaden Geographic and Demographic Scope: Including diverse populations across multiple states to enhance generalizability.
• Incorporate Administrative Data: Utilizing medical records to verify and expand upon self-reported data.
• Isolate Intervention Components: Determining the distinct effects of doulas versus traditional home visitors.
• Explore Long-Term Outcomes: Assessing the sustained impact of doula-home-visiting services beyond the three-month postpartum period.

Conclusion

This RCT provides valuable insights into the potential benefits of incorporating community doulas into home-visiting programs. The significant improvements in childbirth preparation, reduced reliance on pain medication, enhanced breastfeeding initiation, and better infant care practices highlight the multifaceted advantages of such integrated support models.

Addressing existing funding barriers and adopting policy changes to recognize and reimburse doula services can facilitate broader implementation, thereby extending these health benefits to more low-income families. As maternal and infant health continues to be a critical area of public health, studies like this pave the way for more effective and comprehensive support systems.
