More women are having babies over the age of 35 in Canada today – and they have different pregnancy and birth experiences than do their younger counterparts.1
Older women (having their first baby at 35+) are more likely to have a chronic health problem such as hypertension and diabetes before their pregnancy (22%) compared with 13% of 20 to 29 year old women.
Women over 35 are also more likely to have a cesarean birth – compared to women aged 20 to 29 (41% vs. 26%).
Younger women are more likely to report that their pregnancy was unwanted (29%) compared to older women (15%).
Women aged 20 to 29 years are more likely to gain more than 16 kg during their pregnancy (48%) compared to older women (35%).
