ABSTRACT
Objective:To explore the association between body mass index (BMI) and the incidence of thyroid nodules, the clinical characteristics and efficacy evaluation of differentiated thyroid cancer (DTC), respectively.Methods:Clinical data of 1 375 healthy people (1 031 males, 344 females, age: (43.5±10.6) years) who underwent routine physical examination (PE) and 1 450 patients (490 males, 960 females, age: (44.3±12.4) years) with medium-high risk DTC in Tianjin Medical University General Hospital from April 2016 to July 2020 were analyzed retrospectively. PE and DTC patients were classified into underweight group (BMI<18.5 kg/m 2), normal weight group (18.5≤BMI<24.0 kg/m 2), overweight group (24.0≤BMI<28.0 kg/m 2) and obesity group (BMI≥28.0 kg/m 2) respectively. χ2 test was employed to analyze the relation between BMI and thyroid nodules (with/without), BMI and clinical characteristics and efficacy evaluation of DTC, respectively. Logistic regression analysis was used to analyze the independent risk factors for the occurrence of thyroid nodules and the aggressiveness of DTC. Results:Among PE, there were 779 cases with nodules, and 596 cases without nodules. Comparing with those without nodules, more overweight and obese were found in PE cases with nodules (42.1%(328/779) vs 37.2%(222/596), 24.5%(191/779) vs 20.5%(122/596); χ2=13.42, P=0.004). Higher risk of developing thyroid nodules was related with older age and lower thyroid stimulating hormone (TSH) level (odds ratio ( OR): 1.044, 0.919, 95% CI: 1.029-1.060, 0.845-0.999; P<0.001, P=0.046). People with high-risk nodules were more likely to be obese than those with intermediate and lower risk nodules (5/15 vs 24.3% (186/764); χ2=21.11, P<0.001). Among 1 450 DTC patients, comparing with patients with normal weight, patients in the overweight and obesity groups were more likely to have central regional lymph node metastasis ( OR: 1.418, 1.427, 95% CI: 1.075-1.870, 1.044-1.952; P values: 0.013, 0.026), and patients in obese group were with greater risk of lesions being bilateral ( OR=0.696, 95% CI: 0.519-0.934; P=0.016). BMI was not related with the efficacy evaluation of DTC ( χ2=9.13, P=0.425). Conclusions:The incidence of thyroid nodules in people with high BMI is higher. DTC patients with high BMI may have more aggressive incidence. But BMI has no correlation with the efficacy evaluation of DTC patients after treatment.
