Data are presented as OR (95% CI). Statistics were carried out using logistic regression. Model 1: adjusted by age and sex. Model 2: adjusted by age, sex, BMI, diabetes, alcohol consumption, household income level, education, and urine iodine creatinine ratio. Model 3: adjusted by age, sex, BMI, diabetes, alcohol consumption, household income level, education, urine iodine creatinine ratio, and working pattern.
