Perceived health status of women with overt and subclinical hypothyroidism.

OBJECTIVE The objective of this study was to investigate the health status of women with overt and subclinical hypothyroidism and relate it to the presence of clinical signs and symptoms of the disease. SUBJECTS AND METHODS A cross-sectional study was conducted on 232 women divided into 3 groups: overt hypothyroidism (n = 14); subclinical hypothyroidism (n = 152), and controls (n = 66). Health status was evaluated by the questionnaire SF-36, and the clinical signs and symptoms of hypothyroidism were assessed with the Billewicz scale modified by Zulewski. The Kruskal-Wallis test followed by the Mann-Whitney U test with Bonferroni correction was applied to compare continuous variables between the groups. To assess the relationship between SF-36 domains and the clinical score, as well as SF-36 domains and serum thyroid-stimulating hormone levels, the Spearman correlation coefficient was calculated. RESULTS Patients with overt hypothyroidism presented systematically lower scores in all SF-36 domains (p < 0.05), both in relation to subclinical hypothyroidism patients and controls. This indicates a great dissatisfaction with health status in this group. Patients with subclinical hypothyroidism presented statistically lower scores in relation to controls with the exception of the role-emotional and bodily pain domains, where although they were not statistically significant, scores were clinically different. Highly negative correlations between SF-36 domains and the clinical score were observed in overt hypothyroidism (physical function r = -0.80, p < 0.01; bodily pain r = -0.74, p < 0.01). CONCLUSION Overt hypothyroidism seemed to be associated with worse perception of health status, negatively associated with clinical score.
