Abstract:
Objective:To explore the effects of different puberty development stages on thyroid morphology and function in women.Methods:From October to November 2017, a multi-stage cluster sampling method was used to select one junior high school in Minhang district of Shanghai, Haimen city of Jiangsu province, Yuhuan city of Zhejiang province and Deqing county of Zhejiang province respectively. A total of 491 girls in the first grade in 4 schools were included in the study. The subjects were examined with thyroid B-ultrasound and physical examination, and their morning random urine samples and fasting blood samples were collected to detect urinary iodine and thyroid function indexes. Puberty Development Self-rating Scale (PDS) was used to evaluate the stages of puberty; multiple linear regression models and logistic regression models were used to investigate the effects of different puberty stages on thyroid morphology and function.Results:There were differences in thyroid status among women at different stages of puberty. Thyroid volume, the rate of nodules and the level of FT4 were lowest in prepubertal period, followed by pubertal period and postpubertal period ( P<0.05). TT3 and FT3 levels were highest in prepubertal period, followed by pubertal period and postpubertal period ( P<0.001), and there was an opposite trend on the abnormal rate. TSH and TT4 levels were not affected by the stage of puberty ( P>0.05). Multiple linear regression analysis and multivariate logistic regression analysis showed consistent results. There was a negative correlation between puberty development and TT3 and FT3 levels. For each 1 point increase in PDS, TT3 and FT3 levels decreased by 0.067 nmol/L and 0.170 nmol/L in Model 1, respectively, and decreased by 0.065 nmol/L and 0.162 nmol/L in Model 2, respectively. Compared with the prepubertal period, the TT3 and FT3 levels were lower in postpubertal period (Model 1: OR=0.337, 95 %CI: 0.173-0.658; OR=0.283, 95 %CI: 0.144-0.557; Model 2: OR=0.306, 95 %CI: 0.155-0.605; OR=0.263, 95 %CI: 0.132-0.524). Conclusions:The process of puberty is related to the thyroid status in women. The better matured during the puberty, the larger volume the thyroid was, more likely the thyroid nodules appeared, and the levels of TT3 and FT3 was much lower.
