Abstract:
Objective To investigate the correlation between iodine nutritional status and thyroid diseases in some areas of Ningxia. Methods The physical examination, questionnaire survey, and measurement of urine iodine, thyroid function, thyroid associated antibodies were performed, with thyroid ultrasonography in Jingyuan County, Xingqing District and Guyuan City, Ningxia Yinchuan City, totally including 2827 adults. Results The median urinary iodine of all subjects was 258. 7(76. 6-1506. 4) μg/L. The average level of urinary iodine in rural areas [203.3(64. 6-1154)μg/L] was lower than that in cities[340. 7(114. 8-1726. 1)μg/L, Z=19. 514, P>0. 01]. The average urinary iodine level was lower in people over 65 years old[234. 2(58. 9-2285. 4) μg/L, x2=6.449, P=0. 040]. Subjects in hypothyroidism group [232. 5(69. 2-1682. 3) μg/L] had the lowest average urinary iodine level, while hyperthyroidism group[331. 9(102. 4-1862) μg/L] turned to be the highest group( x2=15. 432, P>0. 01). Compared with the normal group, TPOAb and TGAb increased group had similar median levels of urinary iodine (P>0. 05). If compared with single nodule, multiple nodules group and the normal group's median levels of urinary iodine also had no significant difference(P>0. 05). Conclusion Iodine excess was found in the studied population in these areas of Ningxia.
