Abstract

BACKGROUND:

Because the reported frequency of pre-eclampsia in Taiwan varies significantly, the aims of this study were to measure the current incidence of pre-eclampsia and its correlated morbidity and mortality for both mothers and fetuses in Taiwan.

METHODS:

We retrospectively studied all reported cases of pre-eclampsia and eclampsia from January 1, 1993 to December 31, 1997 in the 14 tertiary medical centers and regional hospitals in Taiwan. Recruiting criteria were pregnancy-induced hypertension (systolic blood pressure > or = 140 mmHg or diastolic blood pressure > or = 90 mmHg) with proteinuria (> or = 300 mg of urinary protein per 24 hours) and independent part edema.

RESULTS:

There were 4,193 patients with pre-eclampsia and eclampsia for a frequency of 2.03% of 206,551 deliveries during the study period. Of these, 58.9% of patients were classified as having mild pre-eclampsia while 38.4% had severe pre-eclampsia. Advanced maternal age (> 35 years) (odds ratio [OR] = 4.56; 95% confidence interval [CI] = 4.23-4.90; p < 0.001), primiparity (OR = 1.71; 95% CI = 1.61-1.82; p = 0.02) and twin pregnancy (OR = 1.92; 95% CI = 1.64-2.25; p = 0.01) were significant risk factors for developing pre-eclampsia. However, multivariate analysis showed that only advanced maternal age was a significant risk factor for pre-eclampsia (OR = 3.21; 95% CI = 2.95-3.50; p < 0.001). In contrast to mild pre-eclampsia, severe pre-eclampsia resulted in significantly worse outcomes for both mothers and fetuses. Complications in patients with severe pre-eclampsia included placental abruption, acute renal failure, pulmonary edema, postpartum hemorrhage, pleural effusion, preterm labor, intrauterine growth retardation, stillbirth, neonatal mortality and low birth weight infants, all of which occurred significantly more frequently than in patients with mild pre-eclampsia (p < 0.001).

CONCLUSIONS:

Pre-eclampsia remains a big challenge in modern obstetrics in Taiwan. Early diagnosis and management of patients with pre-eclampsia to prevent progression would significantly improve outcomes for mothers and fetuses.
