Gebelikte İyot Desteği Gerekli Midir? Hastane Temelli Bir Çalışma

Giriş: İyot eksikliği, gebelerde olumsuz etkilere, bebeklerinde ise nörokognitif bozukluklara neden olmaktadır. Çalışmamızda hastanemiz polikliniklerine başvuran gebe kadınlarda iyot eksikliğinin araştırılması amaçlanmıştır. Yöntem: Bu kesitsel ve tanımlayıcı çalışmaya, 2014 yılında takip edilen, 94 gebe dahil edilmiştir. Çalışmaya alınan gebelerin, anlık (spot) idrarda iyot düzeyleri ve tiroid fonksiyon testleri analiz edilmiştir. Spot idrarda iyot düzeyi

Should Iodine be Supported in Pregnancy? A Hospital Based Study

Objective: Iodine deficiency causes adverse effects in pregnant women and neurological-cognitive disorders in their babies.Our aim was to define the status of iodine deficiency among pregnant women, who attended our hospital outpatientpolyclinics. Materials and Methods: This cross-sectional and descriptive study was performed in 2014 with 94 pregnantwomen. Iodine levels in spot urine and serum thyroid hormones have been analyzed. The iodine levels of spot urine less than150 µg/L were accepted as iodine deficiency. Results: The mean age was 30.6±3.92 years, mean gestational age was18.9±9.64 weeks. Mean urinary iodine concentrations (UIC) were 160.32±5.88 μg/L and the ratio of pregnant women whoseUIC less than 150 μg/L was 33% (n=31) and the percentage of the women, who declared iodised salt use was 90.2%.Conclusion: In this study, in one-third of pregnant women the urine iodine concentrations were inadequate despite the highrate of iodised salt intake. Nevertheless, most prenatal vitamins and salts do not include adequate iodine, iodine monitoringand supplementation may be recommended before and during pregnancy.
