1. Stratified analysis of the association between GDM and abdominal circumference (AC) >90th percentile at 28 wkGA.
Stratified analysis of the association between GDM and abdominal circumference (AC) >90th percentile at 28 wkGA. Points are adjusted relative risks, and bars are 95% CI. Stratification was by obesity (BMI ≥30 kg/m2), GDM treatment type (diet only or medication [insulin or metformin]), and year of the 28 wkGA scan (2008–2010 diagnoses were based on a modified version of the 1999 WHO criteria: fasting, 1-h, and 2-h glucose levels >6.1 mmol/L [110 mg/dL], 10.0 mmol/L [180 mg/dL], or 7.8 mmol/L [140 mg/dL], respectively, and 2011–2012 diagnoses were based on the modified IADPSG criteria: thresholds 5.3 mmol/L [95 mg/dL], 10.0 mmol/L [180 mg/dL], or 8.5 mmol/L [153 mg/dL], respectively). One hundred sixteen women had a diagnosis of GDM in the pregnancy, attended for a 75-g fasting OGTT at ∼6 weeks postpartum, and had a normal result (fasting glucose <6.1 [110 mg/dL] and a 2-h glucose <7.8 mmol/L [140 mg/dL]). Analyses were adjusted for the year of the 28 wkGA scan, maternal age, height, ethnicity (Indian/Pakistani/Bangladeshi vs. others), weight gain, and BMI, as appropriate (where the analysis was not stratified by the respective variable). GTT, glucose tolerance test.
