East Asia and the Pacific

The regions of China, East Asia, Southeast Asia and Pacific reflect vast diversity in population, economic development, and public health systems. Despite past successes in iodine deficiency prevention, these regions now face emerging risks linked to shifting diets, market deregulation, and declining awareness of iodine nutrition, particularly among younger generations.

In China, national data show that household use of iodized is declining, accompanied by falling iodine status among pregnant women in several provinces. Misconceptions linking iodized salt to thyroid disease, increased market competition in the salt industry, and reduced public health messaging have contributed to this drop in iodine intake. IGN is focusing efforts on public education campaigns and technical input to national guidelines.

In Mongolia, a national nutrition survey revealed that the risk of iodine deficiency is returning, while at the same time, the Social Indicator Sample Survey removed key indicators on iodized salt coverage, creating new challenges for tracking progress. IGN is engaging with national authorities and partners to strengthen commitment to salt iodization.

IGN is working alongside national governments, salt producers, academic institutions, and partners including UNICEF, WHO, and Nutrition International to keep iodine on the public health agenda. In Cambodia, Vietnam, and the Philippines, IGN is helping governments strengthen fortification regulations and build long-term policy solutions.
