Abstract: Objective：To comprehend the epidemiological status and risk factors in hypertensive disorder complicating in Pudong New Area in Shanghai,in order to provide a method for early intervention of hypertensive disorder complicating. Methods：A total of 4056 pregnant women in our hospital from 2009 to 2012 were retrospectively analyzded and the related factors were evaluated by multivarisate unconditional logistic analysis. Results：The incidence of hypertensive disorder complicating was 5.18%,with gestational hypertension was 2.49%,with preeclampsia slightly was 0.64%,wieh preeclampsia smi was 1.85%,with eclampsia was 0.05%,and pregnancy with chronic hypertension was 0.15%.Multivariate unconditional logistic regression analysis showed that age（OR=7.610,95%CI：2.322-24.936）,body mass index(BMI)before pregnancy（OR=120.715，95%CI：61.867-235.540）, the increased weight during pregnancy（OR=16.219，95%CI6.219-42.316）were risk factors for hypertensive disorder complicating. Conclutions：Age,BMI before pregnancy,the increased weight during pregnancy,primiparity,and pregnant with no antenatal examination are risk factors for hypertensive disorder complicating.While parity have no obvious correlation with hypertensive disorder complicating.
