Objective To have knowledge about the prevalence of thyroid diseases in female teaching staff of colleges and to take effective prevention measures.Method Data of mass screening for thyroid diseases in female teaching staff of a certain college from physical examination in 2006and 2012was retrospectively analyzed.Results Total detection rate of thyroid diseases was 39.37%（176/447）

in which diffuse goiter accounted for 7.95%（14/176）and thyroid nodule accounted for 92.05%（162/176）.Detection rate of thyroid nodule in the year 2006was 36.7%and that was 41.7%in 2012.Detection rate of thyroid nodule gradually increased with age

and differences in detection rate of thyroid nodule in different age groups were statistically significant（p<0.05）.The nodules were mainly solitary nodules with diameter<1.0cm.Hypoechoic nodules in the ultrasonographic appearance accounted for 64.42% and combined calcification accounted for 10.37%.Nodules with occurrence site in right lobe accounted for 51.83%.Conclusion Detection rate of thyroid diseases in female teaching staff of a certain college is relatively high.Regular mass screening is an effective measure for early discovery

early diagnosis and early treatment of the disease.
