The association between postpartum depressive symptoms and contraception.

BACKGROUND: Postpartum depression affects 10% to 20% of birthing people and is associated with changes in healthcare use. Little is known about the association between postpartum depressive symptoms and choice to use contraception; however, both untreated or undertreated depression and short interpregnancy intervals pose substantial perinatal health risks. OBJECTIVE: This study aimed to evaluate whether postpartum depressive symptoms are associated with changes in decisions to use any method of contraception. STUDY DESIGN: This retrospective cohort study included birthing people who delivered between 2017 and 2022 and were referred to a collaborative care program for mental healthcare. Through this program, birthing people with mental health conditions have access to specialized perinatal mental healthcare and prospective symptom monitoring via a patient registry. Postpartum depressive symptoms are assessed via the Patient Health Questionnaire-9, and scores were stratified by severity according to clinical cutoffs. Contraceptive method choice was determined by documentation in the electronic health record and dichotomized as "none" if the participant declined all forms of contraception both at delivery and at the postpartum visit. Bivariable and multivariable analyses were performed. RESULTS: Of the 1871 participants that met the inclusion criteria, 160 (8.5%) had postpartum Patient Health Questionnaire-9 scores of >14, representing moderately severe or worse depressive symptoms, and 43 (2.3%) had severe (Patient Health Questionnaire-9 of >19) depressive symptoms. Birthing people with higher Patient Health Questionnaire-9 scores were more likely to have medical comorbidities; to have a higher body mass index; to self-identify as Black, Native Hawaiian or Pacific Islander, or Hispanic or Latina; and to have a preterm delivery and less likely to be married or nulliparous than those with Patient Health Questionnaire-9 scores of ≤14. There was no difference in any other sociodemographic or clinical characteristics. The choice to use any contraceptive method decreased with increasing depressive symptoms in bivariable and multivariable analyses, reaching statistical significance in birthing people with severe depressive symptoms (adjusted odds ratio, 2.92; 95% confidence interval, 1.46-5.84). CONCLUSION: Severe perinatal depressive symptoms are associated with a declination of any form of postpartum contraception. This finding becomes increasingly relevant as abortion access continues to be threatened across the United States, compounding the potential effect of opting not to use contraception.

Association Between Antenatal Depression Symptom Trajectories and Preterm Birth.

OBJECTIVE: To evaluate whether, among pregnant people referred for mental health care, improvement in antenatal depression symptoms before delivery was associated with a reduction in preterm birth. METHODS: This retrospective cohort study included all pregnant people referred to a perinatal collaborative care program for mental health care who delivered between March 2016 and March 2021. Those referred to the collaborative care program had access to subspecialty mental health treatment, including psychiatric consultation, psychopharmacotherapy, and psychotherapy. Depression symptoms were monitored with the self-reported PHQ-9 (Patient Health Questionnarie-9) screens in a patient registry. Antenatal depression trajectories were determined by comparing the earliest prenatal PHQ-9 score after collaborative care referral with the score closest to delivery. Trajectories were categorized as improved, stable, or worsened according to whether PHQ-9 scores changed by at least 5 points. Bivariable analyses were performed. A propensity score was generated to control for confounders that were significantly different on bivariable analyses according to trajectories. This propensity score was then included in multivariable models. RESULTS: Of the 732 pregnant people included, 523 (71.4%) had mild or more severe depressive symptoms (PHQ-9 score 5 or higher) on their initial screen. Antenatal depression symptoms improved in 256 (35.0%), remained stable in 437 (59.7%), and worsened in 39 (5.3%); the corresponding incidence of preterm birth was 12.5%, 14.0%, and 30.8%, respectively ( P =.009). Compared with those with a worsened trajectory, pregnant people who had an improved antenatal depression symptom trajectory had a significantly decreased odds of preterm birth (adjusted odds ratio 0.37, 95% CI 0.15-0.89). CONCLUSION: Compared with worsened symptoms, an improved antenatal depression symptom trajectory is associated with decreased odds of preterm birth for pregnant people referred for mental health care. These data further underscore the public health importance of incorporating mental health care into routine obstetric care.

The association between adverse childhood experiences and perinatal depression symptom trajectories.

BACKGROUND: Having a history of adverse childhood experiences is associated with an increased risk for treatment-resistant depression in the general population. Whether this relationship is true in the perinatal context is unknown. OBJECTIVE: This study aimed to examine the association between adverse childhood experiences and the trajectories of antenatal and postpartum depression among people enrolled in a perinatal collaborative care program for mental healthcare. STUDY DESIGN: This retrospective cohort study included all pregnant and postpartum people who were referred to and enrolled in a perinatal collaborative care program for mental healthcare and who delivered at a single, quaternary care institution between March 2016 and March 2021. Individuals referred to the collaborative care program were linked with a care manager and had access to evidence-based mental health treatment such as a psychiatric consult, pharmacotherapy, and psychotherapy. All individuals enrolled in the collaborative care program underwent adverse childhood experience screens at intake. A score of >3 on the validated Adverse Childhood Experiences Questionnaire was defined as a high adverse childhood experience score. Depression symptom monitoring occurred via electronic Patient Health Questionaire-9 screening every 2 to 4 weeks, and escalation of care was recommended for those without evidence of improvement. Antenatal depression trajectories were determined by comparing the earliest available prenatal Patient Health Questionaire-9 score closest to the time of referral to collaborative care with the latest Patient Health Questionaire-9 score before delivery. Postpartum trajectories were determined by comparing the earliest postpartum Patient Health Questionaire-9 score after delivery with the latest score before 12 weeks' postpartum. Depression trajectories were categorized as improved, stable, or worsened based on whether the Patient Health Questionaire-9 scores changed by at least 2 standard deviations (ie, 5 points on the Patient Health Questionaire-9 scale). Bivariable and multivariable analyses were performed. RESULTS: Of the 1270 people who met the inclusion criteria, 294 (23.1%) reported a high adverse childhood experience score. Those with a high adverse childhood experience score were more likely to experience a worsened antenatal depression trajectory than those with a low adverse childhood experience score (10.3% vs 4.3%; P=.008). This association persisted after adjusting for potential confounders (adjusted odds ratio, 2.39; 95% confidence interval, 1.05-5.46). There was no significant difference in the postpartum depression trajectories between those with a high and those with a low adverse childhood experience score. CONCLUSION: Having a high adverse childhood experience score is associated with a worsened antenatal depression trajectory for those enrolled in a collaborative care program. Given its high prevalence, future research should evaluate effective modalities of perinatal depression prevention and treatment specific for pregnant people with a history of adverse childhood experiences.
