Life course pathways to prenatal maternal stress

Area of Science:

• Psychology
• Public Health
• Sociology

Background:

• Prenatal stress is a significant concern with potential adverse outcomes for both mother and child.
• Understanding the origins of prenatal stress, including early life experiences, is crucial for effective intervention.
• Previous research has explored various risk factors, but the interplay of childhood and adult stressors requires further investigation.

Purpose of the Study:

• To examine the influence of recalled childhood stressors and adult stressors on perceived stress during pregnancy.
• To identify specific childhood factors (e.g., family cohesion, social support, socioeconomic position) and their pathways to prenatal stress.
• To assess the direct and indirect effects of adult factors on perceived prenatal stress.

Main Methods:

• Prospective cohort study design involving 421 pregnant women.
• Recruitment from pre-birth clinics in two diverse communities.
• Statistical analysis to determine associations between recalled childhood stress, adult factors, and perceived prenatal stress, controlling for covariates.

Main Results:

• Recalled childhood stress showed a positive association with prenatal stress (β = .54) after adjustments.
• Low childhood family cohesion indirectly impacted prenatal stress via recalled stress, current cohesion, and socioeconomic position (SEP).
• Low adult subjective SEP (β = -.44) and family cohesion (β = -.25) were directly linked to higher prenatal stress.

Conclusions:

• Prenatal stress arises from a complex interaction between childhood experiences and adult circumstances.
• Findings highlight the importance of lifelong psychosocial risk assessment and interventions to mitigate prenatal stress.
• Interventions targeting early life adversities and current adult factors may reduce adverse pregnancy outcomes.
