Decline in Antidepressant Use During Pregnancy Raises Mental Health Concerns: JAMA

Against the above background, Claire Boone, Department of Economics, McGill University, Montreal, Quebec, Canada, and colleagues offer detailed evidence on the treatment choices made by women and their clinicians regarding depression during pregnancy.

The cohort study adhered to the STROBE reporting guideline and was classified as not involving human participants by the University of Chicago Institutional Review Board. Analyses were performed from January to November 2024 using Merative MarketScan Research Databases, which provide claims data for a large sample of privately insured individuals in the U.S. The study focused on women who gave birth between 2011 and 2017, with prescription drug coverage before, during, and after childbirth. Antidepressant medication fills, and psychotherapy claims for women and their spouses were analyzed over two years.

Key Findings:

• The study included 385,731 women, with a mean age of 31.8 years, 74.8% of whom were employed, and an average income of $84,577.
• 4.3% of women filled an antidepressant prescription before pregnancy, and 2.2% during pregnancy, reflecting a 48.8% decrease.
• No similar decrease was seen in antidepressant use among 217,877 spouses.
• Women did not substitute antidepressants with psychotherapy; in fact, psychotherapy claims slightly decreased during pregnancy.
• Within one month after childbirth, women resumed antidepressant use, but restarting treatment post-pregnancy may leave many women untreated during the high-risk postnatal period.

The findings revealed a significant reduction in antidepressant use during pregnancy, without a corresponding increase in psychotherapy. These findings highlight the importance of addressing mental health treatment options during pregnancy, considering the challenges women face before and after childbirth.

"However, the study has limitations, including the reliance on prescription refills rather than medication adherence, which may not fully capture treatment patterns. Additionally, the absence of survey data prevents further exploration of why women discontinue medication. Finally, the study's focus on privately insured individuals in the U.S. means the results may not apply to broader populations," the researchers concluded.
