Amaç: İyot eksikliği, tüm dünyada gebe kadınları ve çocukları ciddi şekilde etkileyen önemli bir sağlık sorunudur. Araştırmada, Konya ilinde yaşayan gebelerde trimesterlere göre idrar iyot düzeylerinin değerlendirilmesi amaçlanmıştır.
Yöntem: Araştırmaya, 1-40 hafta arasında gebeliği olan 15-49 yaş aralığındaki 395 gebe kadın dahil edilmiştir. Araştırmacılar tarafından oluşturulan soru formu, katılımcıların sosyo-demografik, obstetric ve iyotlu tuz kullanma özelliklerini içeren beslenmeye yönelik 54 sorudan oluşmaktadır.
Bulgular: Katılımcıların, medyan idrar iyot düzeyleri 91,90 µg/L idi. Gebelerin birinci, ikinci ve üçüncü trimesterdeki medyan idrar iyot düzeyleri sırasıyla 104,00µg/L, 93,00µg/L ve 71,00µg/L idi. Üçüncü trimesterdeki idrar iyot düzeyi anlamlı olarak düşüktü (p<0,05). 395 gebe kadının %78,70’inde iyot eksikliği (<150µg/L) olduğu belirlenmiştir. Gebelerin birinci trimesterde %9,90’ında, ikinci trimesterde %15,80’inde ve üçüncü trimesterde %34,40’ında ciddi iyot eksikliği (0-49µg/L) saptandı.
Sonuç: Sonuç olarak, bu çalışmaya katılan gebelerin idrar iyot düzeyi yetersizdi ve bu eksiklik trimester ilerledikçe daha belirgin hale gelmektedir.

Objective: Iodine deficiency is a major health problem globally that seriously affects pregnant women and children. The aim of this study was to evaluate urinary iodine levels in pregnant women living in the province of Konya according to trimester.
Methods: A total of 395 pregnant women aged between 15-49, with gestational periods of 1 to 40 weeks were included in the study. A questionnaire prepared by the researchers, with a total of 54 questions, was used to determine the socio-demographic, obstetric, and iodized salt nutritional characteristics of the participants.
Results: The overall median urinary iodine levels were 91.90 µg/L. The mean urinary iodine levels of the pregnant women in the first, second, and third trimesters were 104.00 µg/L in the first trimester, 93.00 µg/L in the second trimester, and 71.00 µg/L in the third trimester. The urinary iodine level was lower in the third trimester and this difference was significant (p<0.05). The results revealed that 78.70% of the 395 women had iodine deficiency (<150µg/L). Severe iodine deficiency (0-49µg/L) was detected in 9.90% of pregnant women who were in the first trimester, 15.80% of the women in the second trimester, and in 34.40% of the women in the third trimester.
Conclusion: The pregnant women participating in this study had insufficient iodine levels in their urine, and this deficiency became more prominent as the trimesters continued.
