Anthropometric and metabolic characteristics of the subjects.

Data were shown as median (interquartile range). Independent sample T test was used to compare characteristics between two groups. a Skewed distributions were logarithmically transformed for comparison.* P<0.05, **P<0.01, ***p<0.001. pre-BMI, pre-pregnancy body mass index; ISIOGTT: insulin sensitivity index; HOMA-IR, HOMA of insulin resistance index; ALT, alanine transaminase; Cr, Creatinine; TG, triglyceride; TC, total cholesterol; HDL-C, high density lipoprotein cholesterol; LDL-C: low density lipoprotein cholesterol; ApoA1, apolipoprotein A1; ApoB, apolipoprotein B; Lp(a), lipoprotein (a); hsCRP, hypersensitive C reaction protein; SPARC, secreted protein acidic and rich in cysteine; FGF21 fibroblast growth factor 21.

数据以中位数（四分位数间距）表示。采用独立样本t检验对两组间的特征进行比较。偏态分布数据经对数转换后进行比较。* P<0.05，**P<0.01，***P<0.001。孕前体质量指数（pre-BMI，pre-pregnancy body mass index）；胰岛素敏感性指数（ISIOGTT，insulin sensitivity index）；稳态模型胰岛素抵抗指数（HOMA-IR，HOMA of insulin resistance index）；丙氨酸氨基转移酶（ALT，alanine transaminase）；肌酐（Cr，Creatinine）；甘油三酯（TG，triglyceride）；总胆固醇（TC，total cholesterol）；高密度脂蛋白胆固醇（HDL-C，high density lipoprotein cholesterol）；低密度脂蛋白胆固醇（LDL-C，low density lipoprotein cholesterol）；载脂蛋白A1（ApoA1，apolipoprotein A1）；载脂蛋白B（ApoB，apolipoprotein B）；脂蛋白(a)（Lp(a)，lipoprotein (a)）；高敏C反应蛋白（hsCRP，hypersensitive C reaction protein）；富含半胱氨酸的酸性分泌蛋白（SPARC，secreted protein acidic and rich in cysteine）；成纤维细胞生长因子21（FGF21，fibroblast growth factor 21）。
