目的　通过对血清铬含量的测定 ,探讨妊娠期糖尿病孕妇是否缺铬。方法　 2 0 0 0～ 2 0 0 1年 ,选择妊娠期糖尿病孕妇 5 0例 ,正常孕妇 4 7例 ,以电感耦合高频等离子体发射光谱法 (ICP AES)测定两组孕妇血清铬含量。结果　妊娠期糖尿病孕妇血清铬含量较正常孕妇明显降低 ,差异有显著性意义 (P <0 0 5 )。结论　建议妊娠期糖尿病孕妇适量补铬 Objective To determine whether chromium deficiency in pregnant women with gestational diabetes through the determination of serum chromium levels. Methods From 2000 to 2001, 50 pregnant women with gestational diabetes mellitus and 47 normal pregnant women were enrolled in this study. Serum chromium levels were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Results The serum levels of chromium in pregnant women with gestational diabetes mellitus were significantly lower than those in normal pregnant women (P <0.05). Conclusions It is suggested that pregnant women with gestational diabetes mend adequate amount of chromium
