We read the Comment by Arianne Sweeting and colleagues with great interest.¹ The researchers highlighted the Cambridge data, which suggest that accelerated foetal growth might occur between 20 and 28 weeks of gestation, before the diagnosis of gestational diabetes. These data suggested no differences in abdominal or head circumferences at 20 weeks. Our recent study² of babies in South India showed that foetal subcutaneous abdominal adiposity is already higher at 20 weeks of gestation in women who later developed gestational diabetes (4·7 weeks later) compared with those who did not.

妊娠期高血糖：是时候提出难题了？

我们怀着极大的兴趣阅读了 Arianne Sweeting 及其同事的评论。¹研究人员强调了剑桥数据，该数据表明，在诊断为妊娠糖尿病之前，胎儿生长可能会在妊娠 20 至 28 周之间发生。这些数据表明 20 周时腹围或头围没有差异。我们最近对印度南部婴儿的研究²表明，与未患妊娠糖尿病的女性相比，后来患妊娠糖尿病（4·7 周后）的女性在妊娠 20 周时的胎儿皮下腹部肥胖已经更高。
