Background & Aims Preeclampsia is a serious multisystemic disorder leading to maternal and neonatal adverse outcomes. However, little is known about the early markers of this disease. The aim of this study was to investigate the association between prepregnancy liver function and the development of preeclampsia. Methods We enrolled 192 571 Korean women who had their first delivery between January 1, 2008, and December 31, 2014, and had undergone a national health screening examination through the National Health Insurance Corporation during 1‐2 years before delivery. Results Preeclampsia developed in 3973 (2.0%) women. The rate of development of preeclampsia was higher in women with abnormal prepregnancy liver enzyme levels than in those with normal liver enzyme levels before pregnancy. On multivariate analysis, women with abnormal alanine aminotransferase level before pregnancy had a 1.21‐fold increased risk of developing preeclampsia than those with normal alanine aminotransferase level before pregnancy, after adjusting for age, family history of hypertension, hepatitis B virus carrier status, smoking, alcohol status, prepregnancy body mass index and blood pressure. Prepregnancy γ‐glutamyltransferase and aspartate aminotransferase levels were not associated with the risk of preeclampsia development. Conclusion Abnormal prepregnancy alanine aminotransferase level was associated with the development of preeclampsia in a subsequent pregnancy. Further studies are needed to evaluate whether early intervention for liver function before pregnancy can decrease the risk of preeclampsia.
