Influence of Thyroid Disorders upon the Incidence and the Severity of Psychosomatic Symptoms in Patients.

BACKGROUND

Thyroid disorders are an area of public health concern worldwide. The study aimed to examine the incidence and severity of psychosomatic symptoms (distress, depression, anxiety and somatization) in patients with hypothyroidism, hyperthyroidism, Graves' disease and Hashimoto thyroiditis in relation to clinically healthy subjects.

METHODS

This case control study was carried out from Feb to Jul 2019 in Serbia. Total sample consisted of 335 subjects, of both sex. The examined group included patients with thyroid disorders treated at the Special hospital for thyroid gland and metabolism disease. Control group included clinically healthy subjects. The Four Dimensional Symptom Questionnaire a self-assessment questionnaire for psychosomatic symptoms was the measuring instrument. Groups were compared using parametric (t-test) and nonparametric (Pearson chi-square test, Mann-Whitney U test, Kruskal-Wallis test) tests.

RESULTS

The incidence of all psychosomatic symptoms was high in patients with thyroid disease. Distress was found in 59.8% of the patients in the examined group comparing to the control group (12.8±8.2 vs. 8.9±8.1). The score of depression was twice higher in the examined group (2.05±2.99 vs. 1.23±2.47). Anxiety was present in 46.2% patients in the examined group, while somatization was found in 69.7% subjects. In hypothyroidism there was no difference between the examined and the control group regarding the level of anxiety, likewise with the level of depression in the control group and subjects with Graves' disease and Hashimoto thyroiditis.

CONCLUSION

Psychosomatic symptoms were significantly more severe in patients with thyroid disorders compared to the control group.
