Long-Term Maternal Health Outcomes Following Severe Maternal Morbidity: A Cohort Study

Area of Science:

• Reproductive Health
• Maternal Health
• Public Health

Background:

• Severe maternal morbidity (SMM) is a critical indicator of maternal health complications.
• Understanding the long-term health consequences of SMM is essential for improving postpartum care.
• Previous research has highlighted immediate risks, but long-term morbidity requires further investigation.

Purpose of the Study:

• To investigate the long-term morbidity experienced by women with a history of severe maternal morbidity (SMM).
• To assess the adjusted risks of long-term diagnoses and hospitalizations following SMM.
• To identify SMM as a potential warning sign for future health risks.

Main Methods:

• Prospective population-based cohort study conducted at a tertiary medical center.
• Included women with SMM (defined as ICU admission during delivery hospitalization) and a matched comparison group.
• Utilized multivariable Cox proportional hazards regression to analyze long-term outcomes over 6-11 years.

Main Results:

• Women with SMM showed significantly higher risks of cardiovascular (aHR: 4.01) and endocrine morbidities (aHR: 2.17).
• Higher rates of SMM-related hospitalizations (aHR: 1.90) and all-cause hospitalizations (aHR: 2.21) were observed in the SMM group.
• Women with SMM had substantially higher hospitalization rates within the first year postpartum (aHR: 4.94).

Conclusions:

• Severe maternal morbidity is associated with significant long-term cardiovascular and endocrine health risks.
• Women with a history of SMM require ongoing, multidisciplinary medical surveillance.
• SMM serves as a crucial warning sign for substantial future health challenges.
