Methods Five primary schools and their villages were randomly selected in each city every year and the children's goitrous rate, uric iodine,family salt and water iodine,and health education about IDD,and so on were investigated. Results The goitrous rate of the children aging between 8 and 10 years had a tendency of declining. In 2001,the rate was 6.52%;in 2002,5.84% and in
