†Comparison was conducted between the designated patient group and their 1 : 3 age- and gestational age-matched health controls: 44 PIH cases versus 132 corresponding matched controls, 28 GH cases versus 84 corresponding matched controls, 16 PE cases versus 48 corresponding matched controls. ‡Gestational diabetes mellitus (GDM) was defined using the criteria from the International Association of Diabetes and Pregnancy Study Groups based on the results of a standard 2-hour 75 g oral glucose tolerance test at 24-28 weeks of gestation. ALT; alanine aminotransferase; AST: aspartate aminotransferase; BMI: body mass index; DBP: diastolic pressure; GDM: gestational diabetes mellitus; GH: gestational hypertension; HDL: high-density cholesterol; HGB: hemoglobin; LDL: low-density cholesterol; PE: preeclampsia; PIH: pregnancy-induced hypertension; SBP: systolic pressure; TCHOL: total cholesterol; TG: triglycerides; UA: uric acid.
