Importance: Prenatal cannabis use continues to increase, and cannabis remains the most commonly used illegal substance in pregnancy. Accumulating evidence suggests potential adverse effects on fetal and neonatal outcomes following cannabis use in pregnancy.

Objective: To update a living systematic review and meta-analysis to provide a timely understanding regarding cannabis use in pregnancy and fetal and neonatal outcomes.

Data sources: The previous review was updated by searching bibliographic databases MEDLINE, CINAHL, PsycInfo, Global Health, and Evidence-Based Medicine Reviews Cochrane Database of Systematic Reviews from November 1, 2021, through April 4, 2024.

Study selection: Cohort or case-control studies comparing pregnancies with and without prenatal cannabis use on prespecified fetal or neonatal outcomes with adjustment for confounders, such as co-use of tobacco products, were included. Two independent reviewers screened studies, with disagreements resolved through discussion.

Data extraction and synthesis: Included studies were extracted by 1 reviewer and confirmed by a second. Risk of bias was assessed with the Newcastle-Ottawa Scale. Random-effects meta-analyses of unadjusted and adjusted odds ratios (ORs) were performed for all primary outcomes. Results were synthesized using the Grading of Recommendations Assessment, Development, and Evaluation approach.

Main outcomes and measures: Primary outcomes were preterm birth (PTB; <37 weeks of gestation), small for gestational age (SGA), low birth weight (LBW; <2500 g), and perinatal mortality.

Results: For this update, 8 new studies with 1 709 998 participants were added, for a total of 51 studies synthesized (N = 21 146 938). From meta-analyses of adjusted effect sizes, moderate-certainty evidence indicated that cannabis use in pregnancy was associated with increased odds of LBW (20 studies; OR, 1.75; 95% CI, 1.41-2.18), PTB (20 studies; OR, 1.52; 95% CI, 1.26-1.83), and SGA (12 studies; OR, 1.57; 95% CI, 1.36-1.81), and low-certainty evidence indicated that it was associated with greater odds of perinatal mortality (6 studies; OR, 1.29; 95% CI, 1.07-1.55). Previously, the evidence was rated as very low or low certainty.

Conclusions and relevance: Cannabis use in pregnancy was associated with greater odds of PTB, SGA, and LBW even after adjusting for co-use of tobacco products, and confidence in these findings increased from low in the prior review to moderate in the current meta-analysis. The findings of this study may help inform patient counseling and future public health policies.

IMPORTANCE: Intimate partner violence (IPV) affects millions of US residents across the lifespan and is often unrecognized. Abuse of older or vulnerable adults by a caregiver or someone else they may trust is common and can result in significant injury, death, and long-term adverse health consequences.
OBJECTIVE: The US Preventive Services Task Force (USPSTF) commissioned a systematic review to evaluate the benefits and harms of screening for IPV, abuse of older adults, and abuse of vulnerable adults.
POPULATION: The recommendation on screening for IPV applies to adolescents and adults who are pregnant or postpartum, and women of reproductive age. The recommendation on screening in older and vulnerable adults applies to persons without recognized signs and symptoms of abuse or neglect.
EVIDENCE ASSESSMENT: The USPSTF concludes that screening for IPV in women of reproductive age, including those who are pregnant and postpartum, and providing or referring those who screen positive to multicomponent interventions has a moderate net benefit. The USPSTF concludes that the benefits and harms of screening for caregiver abuse and neglect in older or vulnerable adults are uncertain and that the balance of benefits and harms cannot be determined.
RECOMMENDATION: The USPSTF recommends that clinicians screen for IPV in women of reproductive age, including those who are pregnant and postpartum. (B recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for caregiver abuse and neglect in older or vulnerable adults.

Ovarian Aging and Fertility

Author/s:

Women in their late 30s to early 40s who have difficulty conceiving are often unaware that success rates of fertility treatment decline with age, most commonly due to declining ovarian function. Counseling about the high prevalence of infertility and miscarriage may be met with surprise and sadness. Reports of children born to high-profile women older than 50 years may contribute to misconceptions, but these births highlighted in the media were likely achieved with donor oocytes from a younger woman or with oocytes or embryos that were previously cryopreserved. Consistent with declining fertility rates worldwide,1 the fertility rate in the US has declined from 70.9 births per 1000 women in 1990 to 56.1 per 1000 in 2022.2 Simultaneously, the 2019 US Census reported that age at first birth had risen from 27 years in 1990 to 30 years in 2019 as more women postponed first birth.

Reasons for these trends may include lack of a partner, economic insecurity, career aspirations, and long work hours. Concerns about childbearing discrimination, including lack of pregnancy and postpartum support, and childcare challenges also likely influence decisions to delay pregnancy. Results of a questionnaire completed by 5692 US general surgery residents reported that more female than male residents delayed pregnancy because of training (46.8% vs 32.7%; P < .001) and experienced pregnancy/parenthood-based mistreatment (58.1% vs 30.5%; P < .001).3

Nonpharmacologic Treatments for Maternal Mental Health Conditions

Objectives. This systematic review evaluates nonpharmacologic treatments for mental health conditions during the perinatal period (pregnancy and up to 12 months postpartum). We evaluated nonpharmacologic treatments for perinatal individuals with depressive disorders, anxiety disorders, bipolar disorder, post-traumatic stress disorder (PTSD), or obsessive-compulsive disorder (OCD).

Data sources and review methods. We searched MEDLINE®, PsycINFO®, Embase®, CINAHL®, the Cochrane Register of Clinical Trials, the Cochrane Database of Systematic Reviews, and ClinicalTrials.gov from January 1, 2000, to January 17, 2024, to identify relevant randomized controlled trials (RCTs). Nonpharmacologic interventions of interest included, among others, cognitive behavioral therapy (CBT), interpersonal therapy (IPT), exercise, non-directive counseling, behavioral activation, bright light therapy, eye movement desensitization and reprocessing (EMDR), and acupuncture. Outcomes of interest were improvement in scores on psychological assessment tools, cure or resolution of symptoms, suicide-related outcomes, and adherence to treatment. PROSPERO registration number: CRD42023440650.

Results. We identified 103 RCTs. Nonpharmacologic treatments were compared to control or each other in 101 RCTs and to pharmacologic treatments in 2 RCTs. The risk of bias was moderate for the majority of included studies, mostly related to lack of blinding. For perinatal individuals with depressive disorders, CBT was more effective than treatment as usual (TAU) to reduce depressive and anxiety symptoms (both moderate strength of evidence [SoE]); IPT was more effective than TAU to treat depressive symptoms (moderate SoE) and anxiety symptoms (low SoE); and both behavioral activation (a CBT technique, with low SoE) and exercise interventions (moderate SoE) were more effective than TAU to reduce depressive symptoms. Remission rates for depressive symptoms were higher with CBT and IPT compared to TAU (both low SoE) and higher with specific acupuncture than nonspecific or sham acupuncture (low SoE). There were no differences between CBT and non-directive counseling (an active patient-led intervention), between counseling and TAU, and between bright light and placebo light therapy (all low SoE). CBT was more effective than TAU to reduce anxiety and depressive symptoms for individuals with combined depressive and anxiety disorders (low SoE). Few (or no) eligible studies evaluated individuals with anxiety disorder, PTSD, OCD, or bipolar disorders, precluding conclusions for these conditions. There was also insufficient evidence for suicide-related outcomes, potential harms of treatment, and adherence to treatment, and for comparisons of nonpharmacologic with pharmacologic treatments.

Conclusion. Several nonpharmacologic treatments are more effective than TAU for perinatal mental health conditions, with the strongest evidence for CBT and IPT to reduce depressive symptoms among perinatal individuals with depressive disorders or combined depressive and anxiety disorders. Future research is needed to evaluate the comparative effectiveness of lesser studied nonpharmacologic interventions and lesser studied perinatal mental health conditions.

What Is Perinatal Depression?

Author/s: 
Rebecca Voelker

Perinatal depression can occur during pregnancy and the first 12 months after childbirth.

Perinatal depression, also called postpartum depression, affects about 1 in 7 perinatal individuals. More than 75% of these individuals receive no treatment for perinatal depression. Onset of perinatal depression may occur prepregnancy or may develop over the course of pregnancy and the postpartum period. Untreated perinatal depression is associated with an increased risk of suicide and has additional negative effects on the perinatal individual, the fetus (preterm birth, low birth weight), and the child (impaired attachment, which may affect neurodevelopment) and may negatively affect relationships with partners and other family members.

Perinatal Depression: A Guide to Detection and Management in Primary Care

Author/s: 
Manish H Dama, Ryan J Van Lieshout

Introduction: Existing guidelines for primary care clinicians (PCCs) on the detection and management of perinatal depression (PD) contain important gaps. This review aims to provide PCCs with a summary of clinically relevant evidence in the field.

Methods: A narrative literature review was conducted by searching PubMed and PsycINFO for articles published between 2010 to 2023. Guidelines, systematic reviews, clinical trials, and/or observational studies were all examined.

Results: Screening with the Edinburgh Postnatal Depression Scale or Patient Health Questionnaire-9 followed by a diagnostic evaluation for major depressive disorder in probable cases can enhance PD detection. At-risk individuals and mild to moderate PD should be referred for cognitive behavioral therapy or interpersonal psychotherapy when available. Selective serotonin reuptake inhibitors should be used for moderate to severe PD, with sertraline, escitalopram, or citalopram being preferred first. Using paroxetine or clomipramine in pregnancy, and fluoxetine or doxepin during lactation is generally not preferred. Gestational antidepressant use is associated with a small increase in risk of reduced gestational age at birth, low birth weight, and lower APGAR scores, though whether these links are causal is unclear. Sertraline and paroxetine have the lowest rate of adverse events during lactation. Consequences of untreated PD can include maternal and offspring mortality, perinatal complications, poor maternal-infant attachment, child morbidity and maltreatment, less breastfeeding, and offspring developmental problems.

Conclusions: These clinically relevant data can support the delivery of high-quality care by PCCs. Risks and benefits of PD treatments and the consequences of untreated PD should be discussed with patients to support informed decision making.

Postpartum Depression-New Screening Recommendations and Treatments

Author/s: 
Tiffany A Moore Simas, Anna Whelan, Nancy Byatt

Perinatal mental health conditions are those that occur during pregnancy and the year following childbirth, whether onset of the condition(s) predates pregnancy or occurs in the perinatal period. Perinatal mental health conditions are the leading cause of overall and preventable maternal mortality and include a wide array of mental health conditions including anxiety, depression, and substance use disorders. Perinatal depression specifically affects 1 in 7 perinatal individuals. While commonly referred to as postpartum depression, it is more accurately called perinatal depression because its onset corresponds with prepregnancy (27%), pregnancy (33%), and postpartum (40%) time frames.
