Anemia was a public health problem that affect countries with low, middle, or high income. Anemia in pregnant women was very influential on the baby to be born. During pregnancy, the hemoglobin level of pregnant women will decrease due to the hemodilution process, the increased maternal needs and fetus, and the lack of iron intake through supplemented foods. For this reason, the needs of the mother and fetus for iron should be fulfilled. The effect of iron deficiency was not only experienced by the mother but also in the fetus because it caused fetal growth disorders so that the baby will have low birth weight and premature birth. This research objective was to determine the relationship between hemoglobin levels in pregnant women and the growth of newborn liners in Kota Bengkulu.
