Introduction:
The prevalence of thyroid dysfunction (TD) and thyroid autoimmunity (TA) in hospital employees in our country is unknown.
Objective:
To study the prevalence of TD and TA in a group of hospital employees.
Study Subjects And Methods:
We studied thyroid function (thyrotropin, TSH, free thyroxine, T4, and free triiodothyronine, T3) and thyroid autoimmunity (anti-thyroglobulin, antiTg and anti-thyroid peroxidase, antiTPO) in 310 adult subjects (18-70 years) from the hospital General, Segovia, Spain during 2007.
Results:
Eleven subjects (3.5%, 10 women) had previously known TD. Thirty-four subjects (11.0%) were diagnosed of unknown TD, mainly subclinical hypothyroidism (8.4%). Prevalence of total TD was 14.2%. TA was positive in 44 (14.2%) subjects. Both TD (P<0.05) and TA (P<0.05) were associated with female sex, and antiTPO levels were related to the presence of unknown TD (OR 1.007; 95% CI, 1.004-1.010; P<0.001).
Conclusion:
In this population, total prevalence of TD and TA is similar (14%). Increased antiTPO titers are predictors of unknown TD.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
