Abstract
Objective
Identify risk factors of postpartum depressive symptoms (PDS) among preterm infants’ mothers.
Study design
Retrospective cross-sectional analysis of Colorado’s Pregnancy Risk Assessment Monitoring System from 2012 to 2018 included weighted n = 33,633 mothers of preterm infants. Multivariate regression models calculated adjusted risk factors of PDS.
Results
PDS risk factors include history of maternal depression (adjusted risk ratio [aRR] 1.98, 95% confidence interval [CI] 1.28–3.05), early preterm birth <34wga (aRR 1.48, 95% CI 1.05–2.08), no prenatal care (aRR 3.19, 95% CI 1.52–6.71), non-Hispanic other (Asian/Pacific Islander, American Indian/Alaskan, or mixed) race/ethnicity (aRR 1.76, 95% CI 1.10–2.82), and pre-pregnancy public insurance (aRR 2.34, 95% CI 1.46–3.76).
Conclusion
PDS risk factors among Colorado mothers of preterm infants slightly differ from identified risk factors among mothers of term infants. These findings can improve PDS screening and diagnosis so effective therapies and support can be offered during and after NICU hospitalization.
