ABSTRACT
Objective To investigate the iodine nutritional and thyroid stimulating hormone level of patients with thyroid nodules in different regions of Qinghai Province and analyze the characteristics of changes in different regions.Methods In 2014-2016,thyroid nodules in 9 regions of Qinghai Province (Tibetan areasXiewu,Nangqian,Jiegu,Guoluo;non-Tibetan areasXining,Huzhu,Menyuan,Minhe,and Ledu) were selected and serum thyroid stimulating hormone (TSH) and urine iodine were measured.Results A total of 553 thyroid nodules,the median urinary iodine (MUIC) was 160.8 μg/L and the median TSH was 2.97 mU/L.The iodine nutritional status was at an appropriate level.Among them,MUIC (206.8 μg/L) in thyroid nodules in the Menyuan area was slightly higher than the appropriate amount,there was a significant difference in MUIC among different region (x2 =47.747,P < 0.05);of TSH in thyroid nudules in the 9 regions,the differences were statistically significant (x2 =34.832,P < 0.05).Non-Tibetan areas were compared with Tibetan areas,there was a significant difference in MUIC (155.6,185.6 μg/L),TSH (2.68,3.45 mU/L,Z =-3.677,-5.410,P < 0.05);Among them,the differences was statistically significant between MUIC (152.8,187.7 μg/L) of women with thyroid nodules (Z =-3.504,P < 0.05);there was a statistically significant difference in TSH levels among men (2.58,3.46 mU/L) and women (2.80,3.44 mU/L) with thyroid nodules (Z =-3.613,-4.040,P < 0.05);there were no significant differences in MUIC levels among thyroid nodules of each age groups (P > 0.05);of the TSH level in 30-and 50-< 65 years groups (2.63,3.17;2.25,3.58 mU/L),the differences were statistically significant (Z =-2.892,-3.233,P < 0.05),and other groups were no significant differences (P > 0.05).Conclusion The iodine nutrition of patients with thyroid nodules in these regions of Qinghai Province is generally at an appropriate level,the MUIC and TSH levels in Tibetan areas were lower than those in non-Tibetan areas,and iodine nutrition status and TSH levels should be monitored for key populations.
