[The prevalence of antithyroid antibodies in Lleida].
OBJECTIVE
To evaluate the prevalence of autoimmune thyroid antibody, goiter and levels of ioduria in the region of Lleida.


METHODS
Cross-sectional study on a randomized sample of 601 individuals above 6 years old. Examination and palpation of thyroid gland, TSH, T4, FT4, T3, peroxidase antibodies, thyroglobulin antibodies, and ioduria.


RESULTS
The prevalence of positive peroxidase antibodies was 3.4% (IC 95%: 0.9-5.9), and that of positive thyroglobulin antibodies 9.7% (IC 95%: 6.5-12.9). Palpable goiter was found in 18.3% of individuals, and visible goiter in 13.3%. The mean ioduria was 120.2 +/- 68 mg/l. The mean TSH value was higher in the individuals with thyroid autoimmunity (3.4 +/- 2.4 mU/l) than in the rest (1.6 +/- 1.2 mU/l) the difference was significant.


CONCLUSIONS
Although cases of hypothyroidism are common in populations with iodine deficiency, in regions with adequate iodine intake justifies monitoring for hypothyroidism in these populations as well.
