摘要
目的观察上海市闵行区青春期女生的甲状腺激素水平,并探讨其可能的影响因素。方法 2019年1—3月采用分阶段整群抽样方法,分别在上海市闵行区东、南、北和中片各选取1所初中,将其新入学的预初女生共386名纳入研究。对研究对象进行体格检查,并收集其尿样及血样以检测尿碘及甲状腺激素水平;采用青春发育量表(Pubertal Development Scale, PDS)评价研究对象青春发育分期;采用多因素Logistic回归模型分析甲状腺激素水平的影响因素。结果研究对象尿碘质量浓度中位数为163.57(106.57,232.96)μg/L,血清促甲状腺激素(TSH)、血清总三碘甲状腺原氨酸(TT3)、血清游离三碘甲状腺原氨酸(FT3)、血清游离甲状腺素(FT4)几何均值分别为0.29 mU/L、0.26 nmol/L、0.68 pmol/L、1.18 pmol/L,血清总甲状腺素(TT4)均值为91.64 nmol/L。甲状腺球蛋白抗体(TGAb)以及甲状腺过氧化物酶抗体(TPOAb)的偏高率为6.22%及4.15%。TGAb和TPOAb均偏高率为3.68%。青春发动期和青春后期TT4水平均低于青春前期(OR值分别为0.47,0.43),肥胖女生具有较高的TT3水平(OR=9.08,95%CI=1.52~54.07);运动时间增加(0.5~1,>1 h/d),FT4水平增高(OR值分别为2.45,2.19)。TGAb和TPOAb同时偏高者中TSH水平较高;TGAb偏高TPOAb正常的学生中,TT4和FT4水平较高。结论碘适宜地区青春女生甲状腺激素水平与青春期发育、肥胖和运动相关;TSH、FT4和TT4水平与TGAb、TPOAb水平相关。
Objective To investigate thyroid hormone concentration and associated factors among pubertal girls in Minhang District of Shanghai. Methods From January to March 2019, a stratified sampling method was used to select junior high schools from the east, south, north, and middle areas in Minhang district. A total of 386 girls of grade 6 in selected schools were included in the study. Physical examination was conducted, and their urine and blood samples were collected to determine urinary iodine concentration(UIC) and thyroid function. Puberty Development Self-rating Scale(PDS) was used to define the pubertal stage. Logistic regression models were conducted to analyze the associations between pubertal stage and thyroid function. Results The median urinary iodine concentration was 163.57(106.57, 232.96) μg/L. The geometric mean values of TSH, TT3, FT3 and FT4 were 0.29 mU/L, 0.26 nmol/L, 0.68 pmol/L and 1.18 pmol/L.The mean value of TT4 was 91.64 nmol/L. The abnormal rates of TGAb and TPOAb were 6.22% and 4.15%. The rate of abnormal TGAb combined with abnormal TPOAb was 3.68%. Girls in puberty and post-puberty had the lower level of TT4(OR=0.47,0.43) as compared with girls in pre-puberty stage. Obese girls had higher level of TT3(OR=9.08, 95%CI=1.52-54.07). With the increase of exercise time(0.5-1, >1 h/d), FT4 level was increased(OR=2.45, 2.19). TSH levels were significantly higher in girls with higher TGAb and TPOAb. Girls had higher TT4 or FT4 levels if their TGAb levels were higher and TPOAb levels were normal. Conclusion There is an association between pubertal stage, obesity, exercise and thyroid function in school-aged girls during puberty in iodine sufficient areas. TSH, FT4 and TT4 levels are correlated with TGAb and TPOAb levels.
