Abstract:
Objective:To analyze the correlation between simple thyroid nodule and blood lipid and glucose metabolism and iodine nutrition level.Methods:A cross-sectional study was conducted by collecting data of the population undergoing epidemiological investigation in Jinshan District, Shanghai from July to December 2015, to calculate the prevalence of thyroid nodules and analyze relevant functional indicators.Results:Simple thyroid nodules were detected in 603 subjects, with a prevalence of 22.6% (603/2 669). There were 358 female patients with simple thyroid nodules, with a prevalence rate of 26.9%, and 245 male patients with simple thyroid nodules, with a prevalence rate of 18.3%. The prevalence of simple thyroid nodule in female was higher than that in male, and the difference was statistically significant (χ 2=27.686, P<0.001). In addition, the prevalence of simple thyroid nodules increased with age (13.1% (92/704) and 20.2% (104/514) and 25.1% (145/578) and 24.4% (107/439) and 36.3% (98/270) and 34.8% (57/164), χ 2=83.872,P<0.001). In the ≤30 years group (8.0% (30/704) vs. 18.8% (62/331), χ 2=35.716, P<0.001), >30 to ≤40 years old group (14.1% (37/263) vs. 26.7% (67/251), χ 2=12.683, P<0.001), >60 to ≤70 years old group (26.2% (33/126) vs. 45.1% (65/144), χ 2=10.435, P<0.001), and the 70-year-old group (24.4% (21/86) vs. 46.2% (36/78), χ 2=8.521, P<0.001). The prevalence of simple thyroid nodules in males was lower than that in females. In the simple positive thyroid nodule group, Fasting blood glucose (5.12 (4.80, 5.69) and 5.02 (4.72, 5.48)), total cholesterol (1.24 (0.85, 1.86) and 1.13 (0.77, 1.76)), triglyceride (4.77 (4.09, 5.48) and 4.49 (3.92, 5.16)), low density lipoprotein((2.79 (2.26, 3.36) and 2.63 (2.19, 3.16)), and high density lipoprotein cholesterol (1.41 (1.18, 1.66) and 1.35 (1.13, 1.61)) were higher than those in the negative group ( U values were 554 818, 578 468, 535 622, 556 067 and 567 960, respectively, all P<0.01). The BMI index grade distribution of thyroid nodule positive group was higher than that of negative group, and the difference was statistically significant (3.7% (77/2 066), 50.1% (1 034/2 066), 32.4% (669/2 066), 13.8% (286/2 066), 3.2% (19/603), 43.6% (263/603), 38.1% (230/603), 15.1% (91/603), χ2=9.5201, P=0.023). The prevalence of simple thyroid nodules was significantly lower in the iodized salt group than in the non-iodized salt group (20.7% (436/2 102) vs. 29.5% (167/567), χ 2=19.376, P<0.001). The urinary iodine level in the positive thyroid nodule group was significantly lower than that in the negative group (148.4(100.2, 213.7) vs. 169.5(115.4, 241.75), U=545 129.5, P<0.001). After Logistic regression screening, age ( OR=1.57, 95% CI: 1.292-1.908, P<0.001), gender ( OR=1.278, 95% CI: 1.193-1.368, P<0.001), BMI grade ( OR=1.166, 95% CI: 1.022-1.330, P=0.022), total cholesterol ( OR=1.105, 95% CI: 1.005-1.214, P=0.040), iodized salt ( OR=0.689, 95% CI: 0.556-0.854, P=0.001) were independent influencing factors of thyroid nodule. Conclusion:The prevalence of simple thyroid nodules in Shanghai is relatively low. Age, sex, BMI level, total cholesterol and iodized salt are independent factors causing thyroid nodules. In addition, blood glucose level may also be related to the prevalence of thyroid nodules.
