A recent study suggests that the standard recommendation for birth spacing, waiting at least 18 months between pregnancies, may not be appropriate for everyone. Preliminary findings indicate that individuals over 30 years old who have shorter intervals between pregnancies might face a lower risk of preterm birth than previously thought. This could imply that older mothers with a recent live birth may not need to wait as long before attempting another pregnancy. Although the study's estimates are still imprecise, and further research is required, this insight is significant as more people in the U.S. and worldwide have older children. Adjusting birth spacing recommendations based on maternal age could improve pregnancy outcomes and better family planning care.
