Risk factors for pre-eclampsia in pregnant Chinese women with abnormal glucose metabolism

Abstract Objectives To investigate the incidence and risk factors for pre-eclampsia in pregnant Chinese women with abnormal glucose metabolism. Methods A retrospective cohort study was performed on 1499 pregnant women with abnormal glucose metabolism at Peking University First Hospital from January 1995 to December 2004. Results The overall prevalence of pre-eclampsia in women with abnormal glucose metabolism was 9.4% (141/1499). The prevalence of pre-eclampsia in women diagnosed with diabetes mellitus prior to pregnancy was higher than that of gestational diabetes mellitus and gestational impaired glucose tolerance patients (29.1% vs 8.7% and 7.8%, P  Conclusions The type of diabetes, chronic hypertension, and elevated pre-pregnancy body mass index are high risk factors for pre-eclampsia in pregnant women with abnormal glucose metabolism.
