The threshold is a clinical convention, not a biological switch, so clinicians often distinguish ages 40, 45, and 50 when discussing surveillance and counselling, and some risks rise more substantially after age 40. This is now a routine obstetric population in Canada. Statistics Canada reports that mothers aged 35 years or older accounted for 27.1% of live births in 2024, compared with 16.1% in 2000 (the 2024 data are preliminary). The label should prompt a more deliberate risk assessment, not an assumption that the pregnancy is abnormal. Many patients aged 35 or older have uncomplicated pregnancies, and most pregnancies at this age result in healthy parents and newborns. Advanced maternal age is a risk factor.
