ABSTRACT

Objective To evaluate the effectiveness of control and prevention of iodine deficiency disorders(IDD) in Xinjiang Production and Construction Corps. Methods According to the national requirement and the situation of Xinjiang Production and Construction Corps, thirty sampling units were selected by the“probability proportionate to size” method; one school was chosen in each sampling unit; forty children (half male half female) aged 8 - 10 years old were chosen in each school. Family salt samples were collected to detect salt iodine content, and the goiter was determined. Twelve children(half male half female) from the 40 children were selected; urine samples were collected to detect urinary iodine content. Twenty fifth-grade children in each school and five housewives around each school were selected, and the survey of health education knowledge was conducted. Salt iodine was measured using direct titration (GB/T 13025.7-1999);the volume of thyroid was detected by ultrasound ( WS 276-2007 ); urinary iodine was measured by arsenic Ce catalytic spectrophotometry method (WS/T 107-2006). Results A total of 1 195 household salt samples were tested. The mean of salt iodine was (30.91 ± 6.99)mg/kg;the coverage rate of iodized salt was 97.49%(1 165/ 1 195);the qualified rate of iodized salt was 98.54%(1 148/1 165); and the consumption rate of qualified iodized salt was 96.07%(1 148/1 195). Twelve hundred and twenty children aged 8-10 years old were examined;forty-two goiters were examined;and goiter rate was 3.44%. Four hundred and seven urine samples were tested, the median of urinary iodine was 235.31 μg/L;< 50 μg/L accounted for 1.47%(6/407); and 50 - < 100 μg/L accounted for 6.63%(27/407). The awareness rates of IDD health education knowledge of the fifth-grade students and housewives were 84.39%(1 519/1 800) and 84.44%(380/450), respectively. Conclusion The level of IDD control and prevention in Xinjiang Production and Construction Corps has been up to the national standard of eliminating IDD.
