In this issue of JAMA, the US Preventive Services Task Force (USPSTF) recommends "that clinicians provide or refer pregnant and postpartum persons who are at increased risk of perinatal depression to counseling interventions" (B recommendation; net benefit is moderate). 1 This recommendation is supported by the accompanying evidence review that evaluated the benefits and harms of primary care-relevant interventions to prevent perinatal depression. 2 Perinatal depression, defined as a major or minor depressive episode that occurs during pregnancy or within the postpartum year, affects approximately 11.5% of new mothers annually in the United States, 3 representing a substantial burden for women and families. In addition to risks to the mother, there are important risks for the infant associated with antenatal depression, including preterm birth, low birth weight, and longer-term temperament and behavioral problems. 4,5 Postpartum depression also is associated with short-and longer-term risk factors for the infant, including effects on bonding and attachment, success of breastfeeding, cognitive and social development, and the risk of future psychopathology. 6 Therefore, the targeted prevention of perinatal depression is important, and if done successfully will improve a broad range of outcomes for women and their children.The USPSTF previously recommended broad screening for acute depression among adults, including pregnant and postpartum women. 7 The current recommendation advances the previous more broad recommendation by focusing on prevention rather than screening for acute illness, and the recommendation calls for a specific treatment intervention. 1 The recommendation to refer women at risk for perinatal depression to counseling is based on evidence from clinical trials. The task force completed a rigorous review of clinical studies to prevent perinatal depression, including psychotherapies, antidepressants, and complementary and alternative medicines. Fifty studies (49 randomized clinical trials, 1 nonrandomized controlled intervention study) met inclusion criteria. Counseling or psychotherapeutic interventions were the most widely studied and were demonstrated to be associated with a lower likelihood of onset of perinatal depression. Other treatment modalities were not supported
