Abstract
Background
Depression is considered one of the most common psychiatric disorders that affects more than 260 million people in all age groups worldwide. Yet, among the geriatric population, in which it can show nonspecific symptoms, depression can be easily underdiagnosed. The objectives of this study are to assess the prevalence of depression among the geriatric population in primary healthcare centers and to estimate the effects of different sociodemographic and medical factors.
Methodology
A total of 408 patients aged 60 years or older were approached in the primary healthcare centers of the eastern region of Saudi Arabia. Using the Patient Health Questionnaire-9, patients were either interviewed or filled the questionnaire by themselves. Questions about sociodemographic data and medical and medication histories were included in the questionnaire.
Results
Of the 408 participants, 173 (42.4%) reported depressive symptoms; 115 (28.2%) of the participants had mild depression, 50 (12.3%) had moderate depression, and 8 (2%) reported moderately severe depression. Correlates of depression included elderly patients aged 75 years or more, of whom 78.9% showed depression compared to 39.3% of those who were 60-65 years old (P = 0.001). Furthermore, the female elderly showed higher rates of depression compared to males (52.8% vs. 35.7%; P = 0.001). A reported 81.1% of the elderly were diagnosed with chronic diseases; approximately half of them were depressed, while only 32.9% of the elderly free of diseases were depressed (P = 0.001).
Conclusions
The prevalence of depression is high among the elderly in the eastern province of Saudi Arabia, especially in those who complain of chronic diseases, older patients, and females. Screening for depression must be employed early to manage depressive symptoms and prevent further complications.
