Association between individual urinary iodine concentrations in pregnant women and maternal/newborn outcomes.

ABSTRACT:

Objective

To assess whether individual diagnosis of low urinary iodine concentration (UIC) in pregnant women is associated with adverse maternal and neonatal outcomes.

Methods

Studies that compared pregnant women with UIC <150 μg/L and those with UIC 150-249 μg/L were systematically reviewed. MEDLINE, Embase, LILACS and CENTRAL were our source databases. Selection of studies, risk-of-bias assessment and data extraction were performed in pairs and independently. Relative risk (RR) with 95% confidence interval (CI) was calculated as an estimate of the effect of iodine <150 μg/L. Stata software was used to perform meta-analyses. The quality of evidence was determined according to the Grading of Recommendations Assessment, Development and Evaluation.
