Methods In 2012, proportional probability sampling method(PPS) was used to select 30 primary schools in seven counties of Changzhou City;50 students aged 8-10 in each school were randomly selected to examine thyroid, and their urine and household salt samples were collected to detect iodine. Thirty pregnant and 15 lactation women were selected to detect their urine iodine in the town where the school was located in. Two drinking water samples were collected to detect iodine in the village where the school was located in. The questionnaire survey of health education was carried out among the children and the housewives. Results A total of 1 500 children were surveyed, and the rate of goiter was 0.07%(1/1 500); the median of urinary iodine was 224.81 μg/L. Five hundred and seventy-two pregnant women and 328 lactation women were surveyed, and the median of urinary iodine was 148.93 μg/L and 147.48 μg/L, respectively. Fifteen hundred salt samples were detected, and the coverage rate of iodized salt was 99.47%(1 492/1 500); the edible rate of qualified iodized salt was 97.67%(1 465/1 500); and the median of salt iodine was 25.46 mg/kg. Sixty water samples were collected, and the median of water iodine was 3.63 μg/L. The health education awareness rates were 77.8%(2 100/2 700) and 88.0%(396/450) of students and housewives, respectively.
