Population-based analysis of hypertensive disorders in pregnancy.
OBJECTIVE
To determine the population-based incidence of hypertensive diseases in pregnancy in Western New York.


METHODS
A database of 77,358 women with singleton pregnancies was analyzed using birth certificate data. The incidence of pregnancies complicated by gestational hypertension, preeclampsia, and eclampsia was determined.


RESULTS
The overall incidence of pregnancy-associated hypertensive disease varied slightly from 1999 to 2003. The incidence of preeclampsia decreased from 1.8% to 1.1% (p < 0.01). This decrease persisted over time, despite controlling for known risk factors, such as body mass index, age, ethnicity, parity, smoking, diabetes, and chronic hypertension.


CONCLUSIONS
The incidence of pregnancy-related hypertensive disorders slightly decreased in our population in the last 5 years, with a decline in the rate of preeclampsia accounting for this change. Further analysis may provide additional insights into the population-based incidence of preeclampsia.
