Older Maternal Age Linked to Increased Risks of Premature Birth and Complications in Newborns
New Swedish study shows that children born to mothers over 45 face higher risks of premature birth and complications, emphasizing the importance of informed pregnancy planning for older women.
Recent research highlights the elevated risks associated with childbirth among women over the age of 45. The study, analyzing data from over 300,000 births in Sweden, reveals that children born to older mothers are more prone to premature birth, low birth weight, and other complications. While giving birth after 40 has become increasingly common worldwide, the findings demonstrate that the highest risks are observed in mothers aged 45 and above. Specifically, the rate of stillbirth in this age group is approximately double compared to women aged 35–39, with 0.83% vs. 0.42%. Premature birth rates also increase significantly: 4.8% in women aged 35–39, rising to 6.1% in women aged 40–44, and reaching 8.4% for mothers 45 and older.
The study emphasizes that, although severe complications like stillbirth are rare overall, the risk amplifies with maternal age. The findings aim to provide clearer insights for women considering pregnancy later in life, aiding in better risk assessment and targeted medical interventions. Conducted collaboratively by Uppsala and Linköping Universities, this research underscores the importance of informed reproductive choices amid social trends of delayed childbirth.
