ABSTRACT
Objective To explore the thyroid volume of children aged 8-10 years in non-iodine high area and iodine high area of Tianjin and to analyze the relationship between thyroid volume and urinary iodine level.Methods In 2016-2017,a cross-sectional study was conducted in non-iodine high area and iodine high area in Tianjin.Totally 356 and 199 children aged 8-10 years were selected,respectively.The urine samples of children were collected and the iodine concentration in urine was measured by "As3+-Ce4+ catalytic spectrophotometry".The thyroid volume was monitored by B ultrasonic method.Results The medians of urinary iodine in the 8,9 and 10 years old age groups in iodine high area (500.00,443.00,407.00 μg/L) were higher than those of non-iodine high area (189.39,168.35,189.90 μg/L,Z =7.162,7.536,6.126,P < 0.05).The thyroid volume of children aged 8 and 9 years in iodine high area (2.81,2.91 ml) was higher than that in non-iodine high area (2.31,2.44 ml,Z =3.474,3.264,P < 0.05).There was a weak correlation between urinary iodine and thyroid volume (r =0.109,P < 0.05).Conclusion The urinary iodine level and thyroid volume of children aged 8 and 9 in iodine high areas are higher than those in non-iodine high areas.
