Depression in geriatrics: a systematic review and meta-analysis of prevalence and risk factors in Egypt.

Abstract

Background: Depression is the most common psychiatric disorder in older adults, even though it is commonly misdiagnosed and undertreated, leading to exacerbations of preexisting medical conditions and even a higher mortality rate. In the present systematic review with meta-analysis, we quantify the magnitude of depression and its associated risk factors among the older adult population in Egypt.

Methods: A thorough literature search was performed from 2010 up to October 2023. The results were presented as proportions or risk difference with a 95% confidence interval (CI) calculated using the random effects model. A sensitivity analysis was performed to examine the robustness of the results.

Results: Our study included 14 articles with 5857 older adults published between 2011 and 2023. All the included studies assessed depression in geriatrics using the Geriatric Depression Scale. Of the 14 studies, 5 were for community-dwelling older adults, 3 were for older adults attending primary health care (PHC) centers, 2 were for hospitalized older adults, 3 were for residing in geriatric homes, and one for residing in geriatric homes, hospitalized older adults, and community-dwelling older adults. The overall prevalence of depression among Egyptian geriatrics was 64.6%. The pooled prevalence of depression was 59.6%, 67.0%, 67.0%, and 62.0% for community-dwelling older adults, older adults people attending PHC, hospitalized older adults, and older adults residing in geriatric homes, respectively. Older adults with chronic illness, female sex, and low-income elders and elders who were not employed had a higher risk for depression with pooled risk differences of 34.9%, 17.8%, 23.8%, and 15.1% (P < 0.05), respectively. In contrast, there was no significant difference in risk for depression in the older adults residing in urban areas compared to rural areas, the older adults aged + 70 compared to those less than 70, individuals with low levels of education or who are illiterate compared with those with higher levels of education and the older adults who live alone compared with those living with family.

Conclusion: More than half of the older adults in Egypt suffer from depressive symptoms. Chronic diseases, female sex, unemployment, and low-income inequality are the most significant factors contributing to depression among Egypt's older adults.
