Objective@#To investigate the detection of thyroid nodules and its influencing factors among residents in Dinghai District, Zhoushan City, Zhejiang Province, so as to provide insights into formulation of thyroid nodule control measures.@*Methods@#Residents who were at ages of 18 years and older and had lived for 5 years or more in Dinghai District were sampled using a multi-stage stratified random sampling method from July to September 2022. Basic information was collected using a basic personal information registration form, the height, body weight, waist circumference and blood pressure were measured, and fasting blood glucose, low-density lipoprotein cholesterol (LDL-C) and urinary iodine were detected. Ultrasound examination of the thyroid gland in the neck was performed using a color ultrasound device; and the detection of thyroid nodules was analyzed and standardized by the population of the Sixth National Population Census in 2010. Factors affecting thyroid nodules using a multivariable logistic regression model.@*Results@#A total of 434 residents were included, with a mean age of (49.97±14.74) years. There were 151 males (34.79%) and 283 females (65.21%). Thyroid nodules were detected in 232 cases, with a crude detection rate of 53.46% and a standardized detection rate of 35.69%, and the crude detection rate was 19.82% for solitary nodules and 33.64% for multiple nodules. Multivariable logistic regression analysis identified gender (female, OR=2.355, 95%CI: 1.520-3.647), age (40 to 59 years, OR=2.344, 95%CI: 1.416-3.878; 60 years and older, OR=5.157, 95%CI: 2.869-9.272), high level of LDL-C (OR=1.706, 95%CI: 1.065-2.734) as factors affecting thyroid nodules.@*Conclusion@#The risk of thyroid nodules is higher among residents who are female, are 40 years and older and have high levels of LDL-C in Dinghai District.
