Multiple factors analysis and case-control study on high-frequency ultrasound for diagnosing thyroid nodules / 国际检验医学杂志

ABSTRACT

Objective To adopt the high-frequency ultrasound to conduct the diagnostic analysis for multiple factors of thyroid nodules and the case-control study to provide the reliable method for accurately diagnosing thyroid nodules.Methods The question-naire survey was performed on the residents in a region by using the overall random sampling method.The thyroid high-frequency ultrasound examination and the urine iodine value detection were conducted;the individuals with the positive thyroid nodules by high-frequency ultrasound and the individuals without thyroid nodules lesions were divided into the two groups according to the age,gender,occupation and urban-rural matching,400 cases in each group.The two groups were performed the case-control study;the study results were performed the single factor and multiple factors Logistic regression analysis.Results The combination of the single factor and multiple factors analysis showed that the protective factors were correlated with the patient annual income,the higher the income,the lower the probability suffering from thyroid nodules,the individuals with smoking history had the higher probability suffering from thyroid nodules,the detection and analysis showed that the urinary iodine value in the individuals with low prevalence rate of thyroid nodules was generally 100-190 μg/L (P <0.05).Conclusion Conducting the single factor and mul-tiple factors comparative analysis on the patients with thyroid nodules by the high-frequency ultrasound finds that the diet habit and the use amount of iodine have a certain correlation with the occurrence rate of thyroid nodules,the urinary iodine value affects the occurrence rate of thyroid nodules.The high-frequency ultrasound plays a role in the diagnosis of thyroid nodules and can be taken as the promotion application for the diagnosis of thyroid nodules in clinic.
