RESUMO
BACKGROUND: Recent biochemical and physiological investigations have focused on the fundament of mood disorders in thyroid dysfunction. The present study aimed to address depressive disorder in a sample of Iranian hypothyroid women compared to euthyroid individuals. METHODS: Thirty consecutive hypothyroid female patients aged 25 to 40 years who referred to the Endocrinology and Metabolism Clinic at Rasoul-e-Akram Hospital in Tehran within a four-month period in 2015 were assessed. Thirty healthy euthyroid subjects matched for sex, age, and educational level were selected as the control. For assessment of depression status, Depression Anxiety Stress Scale-21 (DASS-21) was employed. RESULTS: The study showed higher mean depression score in hypothyroid patients when compared to euthyroid ones (13.8 ± 9.5 versus 5.8 ± 5.2, p = 0.010). No significant association was revealed between mean depression score and patients' education level (p = 0.627), age (p = 0.967), occupation status (p = 0.211), and marital status (p = 0.556). CONCLUSION: Hypothyroid women are predisposed to depressive symptoms independent of their baseline demographic and socioeconomic characteristics.
