Impact of Severe Maternal Morbidity on Subsequent Pregnancies: Key Findings from Swedish Study

Women who experience severe maternal morbidity (SMM) during their first pregnancy face challenges when having more children, according to a study from the Karolinska Institutet. This research analyzed data from over one million Swedish women who gave birth from 1999 to 2021. Published on November 25, 2024, in JAMA, it reports that about 3.5% of first-time mothers experienced SMM.

Women with SMM were less likely to have another child compared to those without complications. The study shows that there were 136.6 births per 1,000 person-years for women with SMM, compared to 182.4 for those without. This statistic indicates a reduced likelihood for further births after experiencing SMM.

SMM includes serious conditions like severe hemorrhage, sepsis, and heart problems, which can occur during pregnancy and up to 42 days postpartum. Women facing severe uterine rupture and cardiac complications were particularly less likely to have more children, showing nearly a 50% decrease in subsequent births.

Eleni Tsamantioti, the study’s lead author, stressed the need for personalized medical advice for these women. She stated that reproductive counseling and better care are critical for those who have faced severe health challenges during their first childbirth.

The psychological impact of SMM may also affect women’s desires for more children. Trauma from severe pregnancy complications can lead to anxiety about future pregnancies and affect mental health, further reducing the desire for additional children.

To address these concerns, researchers advocate for improved antenatal care and support systems for women recovering from SMM. These recommendations aim to enhance women’s reproductive options following a traumatic first birth.

The study also highlights a broader issue: declining birth rates in countries like Sweden and Denmark. Enhanced public health policies are needed to support women’s reproductive health, especially after difficult experiences during first pregnancies.

The findings reveal the significant and ongoing impact of SMM on women’s reproductive health. The study’s analysis, which controlled for familial factors by comparing women with their sisters, reinforces the need for active healthcare monitoring and support for these women.

These results underline the urgency of providing proper counseling and strong support systems to women impacted by SMM. With better healthcare responses, women can explore their options for motherhood more freely.
