The mean age of women presenting with hypertension during pregnancy was 34.54 years (95% CI: 31.80-37.27) compared with a mean of 30.11 (95% CI: 29.56-30.66) in women that did not (p = 0.002). Women who had a eutocic delivery were also younger: 29.17 years (95% CI: 28.48-29.86) compared with 31.90 years (95% CI: 31.05-32.74;
