Abstract: Objective To investigate the risk factors of gestational diabetes mellitus （GDM） complicated with hyperlipidemia and their related nutritional management measures. Methods From January 2019 to May 2020, pregnant women with GDM who have established prenatal health records in the obstetrics department of a hospital in Langfang City and can carry out prenatal examination according to the requirements of normal prenatal examination were selected as the research objects for blood lipid level detection, and nutritional management was carried out for GDM pregnant women complicated with hyperlipidemia for 8 weeks. Descriptive epidemiological analysis was used to analyze the influencing factors of hyperlipidemia in GDM pregnant women, and the blood glucose and blood lipid indexes before and after nutrition management were compared. Results A total of 782 pregnant women with GDM aged 20-42 years old were investigated in this study, with an average age of （28.41 ± 6.32） years. The gestational age was 24-28 weeks, with an average of （26.14 ± 1.25） weeks.Among them, 139 （17.77%） cases had hyperlipidemia.Multivariate Logistic regression analysis showed that age ≥35 years old（OR=2.280）, pre-pregnancy BMI ≥24 （OR=2.004）, excessive meat intake （OR=2.073） were the risk factors of hyperlipidemia in pregnant women with GDM.After the intervention of nutritional management, GDM pregnant women complicated with hyperlipidemia had lower TG, TC and LDL-C than that before the intervention, and higher HDL-C than thatbefore the intervention （P< 0.05）. Conclusion The risk factors of GDM complicated with hyperlipidemia are age ≥ 35 years old, overweight/obesity before pregnancy and excessive meat intake.Nutritional management should be tailored on an individual basis to achieve more effective control of blood glucose and lipid levels and improve pregnancy outcomes in GDM pregnant women complicated with hyperlipidemia.
