Geriatric Suicide: Understanding Risk Factors and Prevention Strategies Using a Socioecological Model

Suicide is a leading cause of mortality and a recognized public health priority. In the last two decades, older adults (age 65 and older) saw the largest percentage increase in suicide rates. Despite these rising trends, geriatric suicide remains an understudied public health crisis. In this review, we summarize risk factors specific to geriatric suicide using a socioecological framework and the Interpersonal Theory of Suicide of burdensomeness and belongingness. Specifically, we categorize these risk factors into individual, interpersonal, organizational, and policy levels. For each type of risk factor, we review prevention and intervention programs that can help mitigate the risk of suicide among older adults. Some strategies we discuss include early detection, comprehensive healthcare approaches, community-based support systems, and legislative and policy solutions. The paper underscores the need for increased awareness and more targeted research to address the unique challenges faced by the aging population to provide more informed support and prevent suicide mortality.
