Researchers conducted more than five years of observation of more than 500 women who followed the pregnancy program. The result, women with moderate to severe iodine deficiency in their blood, had a lower likelihood of pregnancy about 46 percent when compared with women with normal iodine levels.
According to Dr. James Mills of Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, Maryland, the findings of this study have a very important impact on public health science. The number of women with mild iodine deficiency is high and this lowers a woman’s ability to conceive up to 50 percent in every menstrual cycle.
Iodine plays a very important role in the formation of fetal brain in pregnancy. But previous studies say, nearly 30 percent of women of childbearing age have iodine levels lower than 100 micrograms per liter or lower than normal iodine levels.
During this time pregnant women are encouraged to consume food or supplements containing iodine at least 150 micrograms per day. Unfortunately this recommendation has not been intended for women who are planning a pregnancy.
The study analyzed data on 501 women who stopped using contraceptives and conducted pregnant programs throughout 2005 to 2009. Previously, the research team carried out iodine levels for every woman studied. During the course of the study, these women were asked to write notes about sexual activity undertaken following the date of ovulation and menstrual cycle.
They also use pregnancy test kits and menstrual cycles to determine the occurrence of pregnancy and ovulation. Researchers found that 44 percent of urine samples studied contained iodine levels lower than normal or about one quarter of all urine samples contained moderate to severe iodine levels.
Twelve months later results were obtained, 332 women (71%) had a pregnancy, 42 women (10%) were not pregnant and the rest stopped being sampled for various reasons.
The results of this study again reminded the importance of healthy balanced nutritious food intake for women, both when the woman was pregnant and when planning a pregnancy.
