Low serum selenium in pregnancy is associated with reduced T3 and increased risk of GDM

Thyroid disorders are the most common endocrine affecting women commencing pregnancy. hormone metabolism is strongly influenced by selenium status; however, relationship between serum concentrations and thyroid hormones in euthyroid pregnant unknown. This study investigated maternal status during pregnancy utilizing data from a retrospective, cross-sectional (Maternal Outcomes Nutrition Tool or MONT study) with cohorts two tertiary care hospitals South East Queensland, Australia. Pregnant ( n = 206) were recruited at 26–30 weeks gestation assessed using inductively coupled plasma mass spectrometry. function parameters measured samples lowest (51.2 ± 1.2 µg/L), mean representative of entire cohort (78.8 0.4 µg/L) optimal (106.9 2.3 µg/L). Women low demonstrated reduced fT 3 levels P < 0.05) increased TPOAb 0.01).
