URCIUOLI, Carolina et al. Prevalence of thyroid diseases in a population of the metropolitan area of Buenos Aires. Rev. argent. endocrinol. metab. [online]. 2016, vol.53, n.2, pp.67-72. ISSN 1851-3034.

The prevalence of palpable thyroid morphological abnormalities does not exceed 8% in the adult population. A free program was conducted in the Hospital de Clínicas (University of Buenos Aires) for the detection of thyroid diseases, inviting subjects who were unaware of a history of these diseases. The aim was to establish the frequency of goitre in the selected population, as well as to evaluate the prevalence of functional disorders and thyroid autoimmunity, and to compare these results with the findings of a similar study performed in 2001¹. The subjects were divided into three groups: Group 1 (n = 186) patients with a history of previously known thyroid disorders (excluded subjects); Group 2 (n = 184) subjects with a family history of thyroid disease, other autoimmune diseases, or symptoms that could be attributed to changes in thyroid function (Induced Group), and Group 3 (n = 288) subjects who participated in this program due to mere curiosity (Random Group). Autoimmunity and thyroid function was assessed in 144 randomly selected participants in Group 3. In Group 3, the prevalence of morphological alterations of the thyroid gland was 11.09%. Comparing these results with those obtained 12 years ago in a similar study performed in our hospital, no statistically significant differences were found when the prevalence of morphological thyroid alterations were compared (8.7% vs 11.09%, p=.25). As for thyroid function, subclinical hypothyroidism was found in 6.25%, subclinical hyperthyroidism in 0.7%, and autoimmunity in 11% of subjects evaluated. It was concluded that the prevalence of palpable thyroid abnormalities had not change in the last decade. This study, made in a correctly selected population, is a useful tool for future reference as a control population in Argentina.
