Analysis of thyroid nodules in middle and aged patients with type 2 diabetes mellitus / 中华老年医学杂志

ABSTRACT

Objective To investigate the prevalence and features of thyroid nodules in middle and aged patients with type 2 diabetes mellitus(T2DM). Methods High-resolution ultrasonography was used to detect thyroid nodules in 132 cases middle and aged patients with type 2 diabetes and 89 patients without diabetes.The nodule features and its relationships with related indicators in diabetic patients were analyzed. Results The prevalence of thyroid nodules in middle and aged patients with type 2 diabetes was higher than that without diabetes (67.4％ vs. 53.9％,P＜0.05),and most occurred in 50 to 59 age group (66.7％ vs. 42.9％) without dependence on changes in thyroid functions and volumes.In diabetes group,the prevalence of thyroid nodules were 59.5％ in male and 81.3％ in female (P＜0.05),no obvious difference was observed in the size and number of thyroid nodules between male and female,multiple nodules and micronodule (＜ 1.0 cm) had the higher incidences in both sexes.The prevalence of thyroid nodules was increased with aging,but not with diabetes duration and glycosylated hemoglobin (HbAlc) level (x2 =0.797,P=0.372; x2 =1.078,P =0.229). Conclusions It is common that thyroid nodules combined with diabetes in middle and aged patients,thyroid ultrasound screening and regular following-up of patients aged ≥50 years have important clinical significance.
