Evaluation of the nutritional state of iodine in a population of pregnant women

Introduction: iodine deficit in pregnant women may have a negative effect on the mother and the newborn, and it is associated to several obstetric complications such as spontaneous abortion, fetal death, congenital anomalies, increase of perinatal mortality and cretinism. The World Health Organization (WHO) establishes that iodine deficit is still the main global avoidable cause for mental retardation and brain palsy, and it affects the development and wellbeing of millions of people around the world at different levels. Pregnant women are a vulnerable population with high requirements. No studies in the pregnant women population have been conducted in Uruguay after the universal salt iodation in 1999. Main objective: assessment of iodine nutritional condition in a pregnant women population Secondary objective: to obtain a qualitative impression of the possible sources of nutritional iodine in this population. Methods: a specially prepared nutritional survey was conducted and first morning urine samples were collected to determine ioduria in pregnant women, regardless of the trimester. In this population, iodine deficiency was defined for this population when urine excretion was below 150 mu g/l (WHO, 2007). Results: ninety six urine samples were analysed. Median of the average urinary excretion for this population was 182 mu g/l, normal rates being between 150 and 249 mu g/l. Conclusions: the study confirmed iodine urinary excretion lies within the adequate range established by the WHO.
