Iodine nutrition status thyroid nodule detection and influencing factors in 450 health check-up residents in Chengdu / 公共卫生与预防医学

ABSTRACT

Objective To study the iodine nutrition status and analyze the detection of thyroid nodules and its related influencing factors in 450 health check-up residents in Chengdu area and to provide evidence for the prevention of thyroid nodules. Methods A total of 450 residents who underwent health check-up in the Western Theater General Hospital from January 2019 to January 2022 were selected as the research subjects. The gender, age, weight and other basic conditions of the subjects were investigated, and their urinary iodine levels and occurrence of thyroid nodules were examined. Univariate and multivariate methods were used to analyze the influencing factors of occurrence of thyroid nodules. Results The overall urinary iodine level of the 450 health check-up people in Chengdu area was (96.89 -212.38) μg/L, with an average of (164.86±42.58) μg/L. The urinary iodine level of males was significantly higher than that of females (P60 years old (P60 years old , people in rural areas and people with history of diabetes mellitus in the thyroid nodule group were higher than that in the non-thyroid nodule group, and thyroid stimulating hormone (TSH), thyroglobulin antibody (TGAb) and anti-thyroid peroxidase antibody (TPOAb) were higher than those in the non-thyroid nodule group (P60 years old, history of diabetes mellitus and high levels of TGAb and TPOAb were risk factors for the occurrence of thyroid nodules (P<0.05). Conclusion The overall iodine nutrition level of 450 health check-up people in Chengdu is in the appropriate range, and the detection rate of thyroid nodules is high. It is necessary to strengthen the examination of thyroid nodules in key populations (women , history of diabetes mellitus, the elderly, etc.), and provide early detection and active intervention to prevent the occurrence and progression of thyroid nodules.
