Context: Hypothyroidism is the most prevalent endocrine disorder worldwide, with a prevalence of 4%-5%. Thyroid hormone has a role in neurological development, and hormone deficiency can be manifested by many neurological signs and symptoms such as behavioral disturbances, anxiety, and depressive symptoms.
Aims: To estimate the prevalence of depression among hypothyroid patients attending primary healthcare and endocrine clinic of King Fahad Hospital of the University (KFHU) and to assess the relationship between depression and different factors.
Settings and design: A cross-sectional study was conducted to estimate the prevalence of depression among hypothyroid patients attending the primary healthcare and endocrine clinics of KFHU in Al Khobar.
Materials and methods: Patients were screened for depression using Patient Health Questionnaire-9 screening tool, in addition to obtaining their sociodemographic data, details of their thyroid function status, and other risk factors for depression. Also, patient medical files were used to obtain the laboratory results.
Statistical analysis used: Data were analyzed using the Statistical Package for the Social Science (SPSS) version 23. Continuous data were displayed using mean and standard deviation; categorical data were displayed in numbers and percentage. Chi-square test was used to assess the relationship between the variables. A P value of less than 0.05 was considered as statistically significant.
Results: It was found that 33.9% of patients were depressed with varying degree of depression. Certain symptoms were found to be associated with higher risk of depression such as fatigue, memory problems, hair loss, and gland enlargement.
Conclusion: Depression was concluded to be prevalent among hypothyroid patients. And screening for depression among hypothyroid patients is recommended.
