Risk of recurrence of hypertensive disorders of pregnancy

Advise women with hypertensive disorders of pregnancy that the overall risk of recurrence in future pregnancies is approximately 1 in 5 (see table below)

Prevalence of hypertensive disorder in a future pregnancy Any hypertension in pregnancy Pre-eclampsia Gestational hypertension
Any hypertension Approximately 21% (1 in 5 women) Approximately 20% (1 in 5 women) Approximately 22% (1 in 5 women)
Pre-eclampsia Approximately 14% (1 in 7 women)

Up to approximately 16%

(1 in 6 women)

If birth was at 28-34 week (a) approximately 33% (1 in 3 women)

If birth was at 34-37 weeks: pproximately 23% (1 in 4 women)

Approximately 7% (1 in 14 women)
Gestational hypertension

Approximately 9%

(1 in 11 women)

Between approximately 6 and 12%

(up to 1 in 8 women)

Between approximately 11 and 15%

(up to 1 in 7 women)

Chronic hypertension Not applicable

Approximately 2%

(up to 1 in 50 women)

Approximately 3%

(up to 1 in 34 women)

a) No evidence was identified for women who gave birth at less than 28 weeks, but the committee agreed that the risk was likely to be at least as high, if not higher, than that for women who gave birth between 28 and 34 weeks.
