STUDY DESIGN: Two databases were used. One contains all deliveries at Soroka Medical Center and the other, the Computerized Community Cholesterol Control System (4C), initially aimed for secondary prevention in coronary heart disease patients. The study population includes 14,977 women who were recorded in the 4C database, delivered during the time period of 1.1.2001-1.5.2005 and had a valid lipidogram (n=35,125). After excluding mismatches between the two databases 32,494 lipidograms (14,977 women) were included. In the current study we included 9,343 lipidograms that were obtained during 9 months of pregnancy and 2 months postpartum. Each lipidogram was related to the nearest pregnancy. Association between high lipidogram levels (mean C2 SD) and obstetrical outcome was investigated. RESULTS: The results of Total Cholesterol, Triglyceride, Low Density Lipoprotein and High Density Lipoprotein are described in the following curves, revealing a significant increase of these measures close to the date of delivery. Triglycerides above 327mg%, total cholesterol above 299 mg% and LDL above 180mg% were associated with adverse obstetrical outcome including preeclampsia, GDM and preterm delivery. Only hypertriglyceridemia was associated with increased rate of macrosomia.
