Iodine deficiency is still a widespread problem in western, southern and eastern parts of China, as their iodized salt intake level is much lower than the average national level.
The Chinese government started an iodized salt program in 1995, and it aimed to eliminate iodine deficiency disorders (IDDs) by 2010.
In 2007, 94.3 percent of Chinese used iodized salt, up 0.5 percent from 2006.[1] However, the country's program to fortify salt with iodine has not been fully implemented in some areas. The iodized salt intake rate was below 90 percent in Guangdong, Hainan, Qinghai, Shanghai, Tibet, and Xinjiang.
People with iodine deficiencies are prone to suffering goitre, a swelling of the neck resulting from enlargement of the thyroid gland, which can also lead to learning disabilities. Iodine deficiencies can also cause miscarriages of pregnant women.
In Tibet, epidemiological studies carried out in 1995-1996 by Médecins Sans Frontières and coll. showed that Kashin-Beck disease was associated with iodine deficiency and with fungal contamination of barley grains by Alternaria sp., Trichotecium sp., Cladosporium sp. and Drechslera sp (Chasseur et al., 1997). Indications existed as well with respect to the role of organic matters in drinking water.
