研究显示,大约77%的母亲和相同胎龄中的平均每3/5的婴儿都有血清锌含量的降低(<13μmol/L)。在被检测妇女中,宏量和微量元素营养不足增加锌缺乏的危险度。锌缺乏增加妇女妊娠合并症的危险性,加重妊娠期慢性疾病及产程紊乱,与之相伴的还有乳汁分泌不全,乳汁中锌含量降低等情况。母亲血清锌含量与婴儿脐血中微量元素含量、身高、体重、适应能力和婴儿出生死亡率相关。脐血中锌浓度低于13μmol/L的婴儿在周岁内的特征是线性生长率降低、精神运动发育迟滞及死亡率增加。
Studies show that an average of about 77% of mothers and an average of three fifths of infants in the same gestational age have a reduction in serum zinc levels (<13μmol / L). Among the women tested, undernutrition in macro and trace elements increases the risk of zinc deficiency. Zinc deficiency increases the risk of pregnancy complications in pregnant women, aggravating chronic diseases and labor disorders during pregnancy, accompanied by incomplete milk secretion and decreased zinc content in milk. Serum zinc levels in maternal mothers were associated with trace element levels, height, weight, adaptability, and infant mortality in infants. Infants with a zinc concentration of less than 13 μmol / L in umbilical cord blood are characterized by a reduction in linear growth rate, increased psychomotor retardation and increased mortality in their first years of life.
