Hair chromium concentration (HCC) of normal and diabetic pregnant women was determined by atomic-absorption spectroscopy. For nondiabetic pregnant women the value from 68 hair samples was 472 +/- 61 ng/g (mean +/- 95% CI); for gestational diabetics it was 734 +/- 155 ng/g from 42 hair samples. The difference was highly significant (P less than 0.005). Intermediate hair chromium concentrations were observed in 20 pregnant women with pregestational, overt diabetes mellitus (mean: 575 +/- 182 ng/g). Fifty-two women had a second hair sample taken later during pregnancy that showed a significant decrease in HCC (P less than 0.05). However, this decrease was confirmed only for the diabetic pregnant group. Age and parity did not influence the HCC. The data suggest that impaired utilization of chromium may be a possible etiology for gestational diabetes mellitus.
采用原子吸收光谱法测定了正常孕妇和糖尿病孕妇的头发铬浓度（HCC）。68份非糖尿病孕妇头发样本的HCC值为472±61 ng/g（平均值±95%可信区间）；42份妊娠糖尿病孕妇头发样本的HCC值为734±155 ng/g。差异具有高度显著性（P<0.005）。20例孕前显性糖尿病孕妇的头发铬浓度处于中间水平（平均值：575±182 ng/g）。52名女性在孕期后期采集了第二份头发样本，结果显示HCC显著下降（P<0.05）。然而，仅在糖尿病孕妇组中证实了这种下降。年龄和胎次不影响HCC。数据表明，铬利用受损可能是妊娠糖尿病的一个可能病因。
