Abstract
ObjectiveTo explore the relationship between the occurrence of thyroid nodules with normal thyroid function and age, sex, diet and thyroid related hormones.
MethodsFrom February 2012 to November 2018, the data of 2 454 people who had thyroid nodule screening in Shijingshan Hospital of Beijing were analyzed retrospectively.All the data were classified and summarized to analyze the factors that may affect the occurrence of thyroid nodule.
ResultsIn all 2 454 patients, 909 patients with Thyroid nodule were detected, the detection rate was 37.04%(909/2 454), the detection rate was 32.87%(164/499)in males and 38.11%(745/1 955) in females, which was significantly higher than that in males (χ2=4.684, P=0.030). Multivariate Logistic regression analysis showed that gender (OR 0.608, 95% P 0.0471-0.784), age (OR 0.944, 95% CI 0.935-0.953), iodized salt intake (OR 0.646, 95% CI 0.447-0.934), free triiodothyronine(FT)3 (OR 1.562, 95% CI 1.374-1.775), free thyroxine (FT)4 (OR 0.924, 95% CI 0.889-0.960), thyroid stimulating hormone(TSH) (OR 1.111, 95% CI 1.059-1.167) (all P<0.05), were thyroid nodules independent risk factors of thyroid nodule.The seafood intake (OR 0.867, 95% P 0.674-1.115, P=0.266) is not anindependent risk factor for thyroid nodules occur.
ConclusionThe occurrence of thyroid nodule is closely related to many factors, among which gender, age, iodized salt intake, FT3, FT4 and TSH are the independent risk factors.
