ABSTRACT
Objective To investigate the epidemiological status and risk factors in hypertensive disorder during pregnancy in Pudong New Area in Shanghai. Methods The retrospective study analyzed data of 4 056 maternal residents in the region from 2009 to 2012. The prevalence of hypertensive disorders in pregnancy was analyzed. The related factors for the hypertensive disorder during pregnancy were evaluated by multivariate unconditional logistic analysis. Results The in-cidence of hypertensive disorder during pregnancy was 5.18%, including gestational hypertension 2.49%, preeclampsia-mild 0.64%, preeclampsia-severe 1.85%, eclampsia 0.05%and pregnancy with chronic hypertension 0.15%. The multivari-ate unconditional logistic regression analysis showed that the advanced age (OR=7.610, OR95%CI:2.322-24.936), the high body mass index (BMI) before pregnancy (OR=120.715,OR 95%CI:61.867-235.540) and the excessively increased BMI during pregnancy (OR=16.219,OR 95%CI:6.219-42.316) were risk factors for hypertensive disorder during pregnancy. Conclusion The risk factors for hypertensive disorder during pregnancy are advanced age, the high BMI before pregnancy and the excessively increased BMI during pregnancy. The hypertensive disorder during pregnancy has no relation with the number of pregnancies.
