THE ULTIMATE GOAL of this project is to answer the question "In MILD IODINE DEFICIENCY (ID), should a tablet with vitamins and minerals, including 150 μg iodine/day be administered to pregnant women with a normal diet, to attain a normal cognitive development of the fetus or is there no cognitive deficit from mild ID and no extra iodine is needed?". To answer this question, the investigators planned a randomized, placebo-controlled trial of micronutrient supplementation during pregnancy in Sweden (SWIDDICH) with the follow-up of childrens' COGNITIVE DEVELOPMENT at 18 months, 3.5, 7 and 14 years. Iodine deficiency (ID) is associated with thyroid morbidity and, especially in children, with impaired cognitive development. Sweden introduced iodine fortification of table salt 1936 and mental retardation due to severe ID is eradicated. Is mild ID during pregnancy also eradicated? If not, is this of importance? A national study performed by the investigators in 2007 showed iodine sufficiency in general population, but there are no pregnancy data. Local studies have raised concerns for mild ID during pregnancy in Sweden and a trans-sectional national study is currently ongoing. The burning question for Sweden and the whole world is: is mild ID during pregnancy of importance for the developing brain of the fetus? Two large observational studies have shown association between mild ID during pregnancy and lower verbal IQ or educational performance at school-aged children. The world needs a randomized placebo-controlled trial (RTC) comparing the cognitive outcome in children exposed to mild ID during fetal life with children exposed to normal iodine levels during fetal life. Our HYPOTHESIS is that pregnant women in Sweden have mild ID and that children exposed to mild ID during fetal life have a lower cognitive development, compared to children to mothers taking daily tablet with vitamins and minerals, including 150 ug iodine during pregnancy. The MAIN AIM of the SWIDDICH trial is to determine if children exposed to deficient micronutrition including mild iodine deficiency (ID) during fetal life achieve worse cognitive development compared to children exposed to normal iodine status reached by maternal iodine supplementation.
The aim of the study is to measure urinary milk iodine concentration (MIC), iodine concentration (UIC), thyroid hormones (TSH, FT4) and thyroperoxidase antibodies (TPOab) in breast-feeding women, and UIC in their nursing infants to determine if the levels are adequate, and to see how they can be influenced by 150 ug daily iodine supplementation in breast-feeding women. The hypothesis is that there is a relative iodine deficiency in this sub-population - lactating women and nursing children-, and that this can be influenced by iodine supplementation. Adequate thyroid hormone and iodine levels are very important for small children, when the plasticity of the brain is greatest. This is as a prospective, double-blind, placebo-controlled study of 221 mothers and their infants. In parallel, 90 age-matched healthy non-pregnant women are recruited. Mothers are randomized to 150 µg/day iodide supplementation or placebo. Pregnant women are asked for participation on a visit in pregnancy week 37, at the mother health care (MVC) at Mölnlycke and Skövde. The study will run for approximately 3 months for each individual and begins by sampling A (UIC, TSH, FT4, TPOab) at week 37 of the pregnancy, when mothers also get randomized to 150 µg iodine or placebo. New sampling B (UIC, TSH, FT4, MIC ) is collected when the baby is 3 months old. Thereafter the study is completed. In parallel, 90 healthy non-pregnant, non-lactating women in the same age range are recruited and followed with UIC, TSH, FT4, TPOab for 6 months as a control group. In each case a simple questionnaire is filled and blood is also frozen for future analyses.
