妊娠过程中,孕妇因血容量及红细胞数增加,子宫腺肉肥大,肌红蛋白形成增加以及供给胎儿和胎盘发育过程中增加铁的需要,如摄取不足(或吸收利用不良),体内贮存铁被动员仍不能满足需要时,即引起贫血。这不仅不利于孕妇本身的健康,而且也影响胎儿的生长发育。严重贫血时,胎儿生长发育不良,死胎及婴儿死亡率也比正常孕妇高。为了了解北京市孕妇营养素摄取量及贫血发病情况,我们选择了北京市宣武区妇幼保健院产前健康检查的645名孕妇,测定血中血红蛋白值。红细胞数及细胞压积值。
During pregnancy, pregnant women due to increased blood volume and red blood cell count, uterine gland hypertrophy, increased formation of myoglobin and the supply of iron during fetal and placental development needs, such as ingestion (or poor absorption), the body stores iron Mobilization still can not meet the needs, that is, cause anemia. This is not only detrimental to the health of pregnant women themselves, but also affect the growth and development of the fetus. Severe anemia, fetal growth retardation, stillbirth and infant mortality than normal pregnant women. In order to understand the nutrient intake of pregnant women and the incidence of anemia in Beijing, we selected 645 pregnant women who had been in prenatal health checkup in the Xuanwu District Maternal and Child Health Hospital of Beijing to measure the hemoglobin in the blood. Red blood cell count and cell pressure value.
