(292) Baseline mental health risk stratification in group prenatal care: A comparative analysis

Wednesday, February 11, 2026
10:30 AM - 12:00 PM  
Objective:
Recent trials of group prenatal care (GPC) models show mixed or negative results for key perinatal outcomes, but high-risk subgroups may preferentially benefit. This study aims to characterize baseline mental health profiles across high-risk subgroups enrolled in a GPC trial to inform future risk-stratified analyses of intervention effectiveness. 

Study Design:
Participants enrolled in a randomized trial of a GPC intervention embedded with evidence-based behavioral health techniques had baseline mental health profiles collected using validated assessment tools: Edinburgh Postnatal Depression Scale, Perceived Stress Scale, PROMIS Anxiety scale, and PTSD Checklist. Adolescents (age < 20) and participants with a history of prior preterm birth (PTB) were identified as high-risk for adverse perinatal outcomes, and their profiles were compared with adults and those without a PTB history using crude odds ratios (ORs) and 95% confidence intervals (CIs).  

Results:
Of 307 enrolled participants, 14.7% were adolescents and 8.0% had a prior PTB. Baseline demographics were similar between adolescents and participants with a prior PTB compared to the rest of the sample. Adolescents demonstrated distinct mental health profiles with significantly higher rates of positive screening for depression (42% adolescents vs. 27% adults; OR 1.99; 95% CI 1.02-3.89) and perceived stress (74% adolescents vs. 57% adults; OR 2.19; 95% CI 1.05-4.56), but no differences were seen in trauma or anxiety between age groups. Women with prior PTB showed similar baseline mental health profiles to those without a history across all screening measures. 

Conclusion:

Adolescents had significantly higher rates of baseline depression and stress compared to adults, while those with PTB showed no mental health differences. Our findings suggest that adolescents may be optimal candidates for behaviorally integrated GPC interventions. Future stratified outcome analyses will determine whether baseline mental health profiles predict differential responses, potentially explaining heterogeneous trial results and informing precision prenatal care approaches.
