The level of knowledge about iodine among pregnant women has not been previously evaluated in Trabzon city where is an endemic area of iodine deficiency in the Blacksea region of Turkey. The aim of this study was to determine the level of knowledge about iodine nutrition during pregnancy among pregnant women living in an endemic goiter area of Turkey. Methods: One hundred fifty pregnant women between ages 19-45 years who applied to Gynecology and Obstetrics Clinic in Trabzon were recruited. This cross-sectional study was conducted with one hundred and fifty pregnant women between the ages of 19-45 who applied to Trabzon Gynecology and Obstetrics Clinic. Research data were collected using questionnaire forms and face-to-face interviews. The questionnaire form consisted of questions determining the sociodemographic characteristics of the participants, their previous pregnancy data, iodized salt consumption habits, and knowledge about iodine. Results: Although 68% of women know that iodine deficiency can cause serious consequences during pregnancy, about 30% did not know the problems caused by iodine deficiency. Three main dietary source of iodine in Turkey, fish, milk and dairy products and table salt are 68.0%, 20.0% and 77.3% of them correctly identified as good sources, respectively. The mean iodine knowledge score of the participants was 8.5±4.5. Higher educated pregnant women had significantly higher knowledge scores (p<.05). However, age, trimester, parity and those who had received information about iodine and iodine knowledge score between no significant differences (p>.05). Conclusion: This study revealed that lack of knowledge about iodine in pregnant women living in an endemic goiter area of Turkey. Furthermore, pregnants also had limited knowledge about the most important dietary iodine sources that can meet their daily iodine requirements. The necessity of public education initiatives to improve iodine knowledge in the pregnant population is evident for healthier future generations.
