ABSTRACT
Objective To investigate the current status of iodine deficiency disorders (IDD) in Jiangsu Province and to evaluate the effects of preventive and control measures on IDD in Jiangsu Province in 2014.Methods With the use of probability proportional to size sampling method (PPS),30 counties (cities,districts)in Jiangsu Province were selected.Only 1 primary school was selected in each county (city,district) and 50 students of 8-10 years old (halt male and half female,uniformly distributed in age groups) were selected in each school.Goiter,salt iodine,urinary iodine,height and weight were examined.Thirty students from Grade 5 in each school were selected at random,and health education questionnaire survey was conducted.In the area where the primary school located,5 housewives were selected and a questionnaire survey was conducted.Two-5 drinking water samples from the village where the primary school located were collected and the water iodine concentration was tested.Urine samples and salt samples from 20 pregnant women and 10 lactating women in the village where the primary school located were collected,and urinary iodine and salt iodine were detected.Thyroid volume was measured by palpation method and ultrasound.Urinary iodine was detected by arsenic cerium catalytic spectrophotometry (WS/T 107-2006).The iodine level in salt was determined by direct titration;the salt samples from Sichuan and other enhanced salt were detected by arbitration (GB/T 13025.7-1999).Water iodine was tested using the method suitable for iodine deficiency and high iodine areas (recommended method of reference laboratory of national iodine deficiency disorders).Results A total of 1 524 children aged 8-10 years old were examined.Forty-two children had goiter by palpation method and the goiter rate was 2.76% (42/1 524).Forty-one children had goiter by ultrasound and the goiter rate was 2.69% (41/1 524).Totally 1 523 urine samples of children aged 8-10 years old were tested and the median of urinary iodine was 208.03 μg/L.A total of 1 524 salt samples were tested,the coverage rate of iodized salt was 97.44% (1 485/1 524) and the qualified rate of iodized salt was 96.43%(1 432/1 485).The consumption rate of qualified iodized salt was 93.96%(1 432/1 524) and the consumption rate of non-iodized salt was 2.56%(39/1 524).The rates of knowledge awareness about IDD among students and housewives were 81.36% (2 287/2 811)and 91.18% (424/465),respectively.Sixty drinking water samples were collected and the median of water iodine was 16.83 μg/L.Six hundred urine samples of pregnant women and 304 urine samples of lactating women were tested.The median of urinary iodine was 155.16 and 138.33 μg/L,respectively.Conclusions After achieving the goal of eliminating IDD,the control effect in Jiangsu Province is sustainable.The crowd's risk of iodine deficiency has declined significantly.
