Evaluation of Iodine Nutritional Status Among Pregnant Women in China

Remarkable achievements have been made for over two decades by implementing a universal salt iodization policy in China.

Therefore, we aimed to evaluate iodine nutritional status using thyroid function and urinary iodine levels in pregnant women via a national survey.
