OBJECTIVES: We examined the gender-specific symptom prevalences in hypothyroidism and in healthy controls and explored the extent to which symptoms indicative of thyroid status may be different in women and men.

DESIGN AND METHODS: Patients newly diagnosed with overt autoimmune hypothyroidism (n = 140) and controls free of thyroid disease (n = 560) recruited from the same population participated in a population-based study of The Danish Investigation of Iodine Intake and Thyroid Diseases (DanThyr). Participants underwent a comprehensive programme including blood tests and completion of questionnaires. The gender-specific distribution of 13 hypothyroidism-associated symptoms and a simple combined score (0-13) was explored in conditional uni- and multivariate models taking into account a broad spectrum of possible confounders. Diagnostic odds ratios (DORs) were calculated as measures for the association between participant status (case vs control) and presence of symptoms (yes vs no).

RESULTS: In overt autoimmune hypothyroidism, 94·9% of women and 91·3% of men (P = 0·62) reported at least one of the hypothyroidism-associated symptoms, with tiredness as the most common symptom followed by dry skin and shortness of breath. In contrast, women free of thyroid disease self-reported at least one hypothyroidism-associated symptom considerably more often than men (73·7% vs 51·1%, P < 0·001). DORs (±SEM) for 0-1/2-3/4-13 symptoms were 0·07 (0·04-0·10)/2·15 (1·57-2·94)/7·99 (6·15-10·4) in men and 0·21 (0·16-0·28)/0·62 (0·58-0·66)/1·99 (1·90-2·09) in women.

CONCLUSION: The presence of symptoms is more indicative for overt autoimmune hypothyroidism in men than in women, and presumably persistent symptoms after therapy of hypothyroidism will be more common in women.
