ABSTRACT:

Background and objectives

This study investigated the iodine status of pregnant women at an average altitude of approximately 2000 meters in Qujing, China. The relationship between iodine and thyroid function in different trimesters as well as adverse pregnancy and fetal outcomes were also investigated.

Methods and study design
