Abstract:
Objective To study the relationship between the prevalence of thyroid dysfunction and components of metabolic syndrome.Methods A total of 10 461 working and retired employees aged 20 to 90 years in a Petrochemical Corporation in Ningbo were included.Body mass index ( BMI),waist circumference,blood pressure,fasting blood glucose,blood lipid profile,serum thyroid-stimulating hormone (TSH),free thyroxine ( FT4 ),and free triiodothyronine (FT3 ) were measured in all subjects. Metabolic syndrome was diagnosed according to the International Diabetes Federation(IDF) criteria.Results ( 1 ) The prevalences of metabolic syndrome and overall thyroid dysfunction were 10.2％ and 4.6％,respectively. ( 2 ) 18.1％ petrochemical employees had abdominal obesity with at least one component of metabolic syndrome.( 3 ) There was no significant difference in the prevalence of metabolic syndrome among the groups with lowered,normal,and elevated TSH. (4) Logistic regression analysis revealed that lowered high density lipoprotein cholesterol ( HDL-C ) was associated with lowered TSH ( OR =0.313,95％ CI 0.184-0.530 ),and raised triglyceride was associated with elevated TSH ( OR =0.767,95％ CI 0.595-0.991 ). ( 5 ) There were significant associations between serum TSH levels and lipid parameters such as total cholesterol in males,triglyceride and low density lipoprotein cholesterol in females,and HDL-C in both genders.Conclusion The prevalence of thyroid dysfunction was not associated with central obesity,hypertension,and hyperglycemia.Lipid disorder was correlated with serum TSH levels.
