Iodine Impact on Thyroid Function and Psychomotor Development, Observational Study in the Portuguese Minho Region

IodineMinho
Start date: January 10, 2020
Phase:
Study type: Observational

Full intellectual capabilities are achieved only if crucial nutrients are present during development. Iodine deficiency is the most common cause of preventable brain harm in infants. Because of its critical need during pregnancy, several countries implemented programs of iodine supplementation in preconception and pregnancy. In 2013, the prevalence of iodine deficiency in Portugal has led health authorities to issue a recommendation for iodine supplementation. This study aims to evaluate the impact of iodine supplementation on maternal and fetal iodine status and thyroid function, obstetric outcomes, quality of breast milk and child psychomotor development. It also intends to evaluate whether the time of iodine supplementation initiation influences all the above-mentioned parameters. The novelty and relevance of this study reside on the number of women/child and on the extent of health parameters that will be evaluated. The information collected will contribute to the detailed characterization of thyroid hormone homeostasis throughout pregnancy and its relationship with iodine supplementation (including time of initiation). The data will provide evidence on whether this iodine supplementation strategy impacted on iodine sufficiency of the mother and the newborns, or if it needs re-evaluation.

NCT ID: NCT02017080 Recruiting - Clinical trials for Hypothyroidism in Pregnancy

Fetal Thyroid Ultrasound And Fetal Thyroid Hormones

Start date: January 2014
Phase: N/A
Study type: Observational

Non invasive methods: maternal antithyroid antibodies and ultrasound measurement of the fetal thyroid gland could be an important tool for detecting fetal thyroid dysfunction in mothers with autoimmune thyroid disease.
