Resumen

Background: Iodine is an essential trace element implicated in syntesis of thyroid hormones. Iodine requirements vary throughout life. These iodine requirements are increased during pregnancy and breastfeeding. In a previous study carried out by our group in 2008, we detected by means of neonatal TSH determinations an iodine-deficient area in the province of Huelva, especially in the Sierra de Huelva-Andévalo district. Objective: Reinforce the iodine supplementation campaign and its impact on newborns in order to assess nutrition iodine status in pregnant women using questionnaires and ioduria determination. Material and methods: This study has been jointly carried out by Congenital Hypothyroidism Unit of the Clinical Biochemistry Department of the Virgen Macarena University Hospital (Seville) and the Gynecology and Clinical Analysis Unit of the Riotinto Hospital (Huelva) for two years. We studied 313 pregnant women. All of them filled out a personal questionnaire to know the iodine nutritional status in their area. Ioduria was determinated by high-resolution liquid chromatography. Data fron pregnant women and results of the studied variables were analized with SPSS v.13.0. Conclusions: Pregnant women from the health district Sierra de Huelva-Andévalo present a median for ioduria which corresponds to an insufficient iodine intake according to the WHO classification. The questionnaires suggest that this iodine deficiency is the consequence of an insufficient iodine intake and a low adherence to the treatment.
