  1. aPreBMI Prepregnancy body mass index, AC Abdominal circumference, ACHtR Abdominal circumference/height ratio
  2. Values are mean (SD) or medians (interquartile ranges). BMI were divided into four groups: low weight(BMI < 18.5), normal weight (18.5 ≤ BMI < 24.0), overweight (24.0 ≤ BMI < 28.0) and obese (BMI ≥ 28.0); AC were divided into three groups according to the quartile(Q1, low-AC group(< 74.0 cm);Q2/Q3, normal-AC group(74.0–86.0 cm); Q4, high-AC group(> 86.0 cm); ACHtR were divided into three groups according to the quartile (Q1, Low- ACHtR group(< 0.46);Q2/Q3, Normal-ACHtR group(0.46–0.53); Q4, High-ACHtR group(> 0.53))
