FLORES-REBOLLAR, Armando et al. Prevalence of autoimmune thyroiditis and thyroid dysfunction in healthy adult Mexicans with a slightly excessive iodine intake. Nutr. Hosp. [online]. 2015, vol.32, n.2, pp.918-924. ISSN 1699-5198.

Objective: the purpose of this study was to evaluate the prevalence of autoimmune thyroiditis and thyroid dysfunction in healthy individuals with no previously known thyroid disease, in an urban area of Mexico City. Subjects and methods: the study was conducted on volunteers with no known thyroid disease. We recruited 427 subjects among the hospital's medical and administration personnel. All underwent thyroid ultrasound (US) and TSH, free T4 (FT4), total T3 (TT3), thyroid anti-peroxidase (TPOAb) and anti-thyroglobulin (TgAb) antibodies were measured. Hypoechogenicity and thyroid volume were determined by US. Urinary iodine (UI) excretion was also measured. Results: the frequency of autoimmune thyroiditis was 8.4% (36/427) and women were most commonly affected than men (11.6 vs. 4.3% respectively, P = 0.008); when including cases of atrophic thyroid, the frequency increased to 15.7% (67/427). Clinical hypothyroidism was detected in 1.2% (5/427) and it was sub-clinical in 5.6% of individuals. A goiter was present in 5.9% (25/427) of volunteers. Median UI was 267 ìg/L, (IQR 161.3 - 482.5). Conclusions: in spite of our study's limitations, the frequency of autoimmune thyroiditis is clearly elevated in the studied population. Further studies are necessary in order to define the prevalence of autoimmune thyroid disease as well as the current iodine nutritional status in our country.
