There are a large group of older individuals suffering from social isolation and loneliness; in fact, the number of older adults affected is increasing due to the large aging population worldwide. Within the United States, the baby boomers are or will be potentially facing social isolation and loneliness in great numbers. The current research literature in this area is difficult to interpret because the variable used to define social isolation and loneliness varies across disciplines when looking at this problem. Intervention research has also produced mixed findings. This article looks at this public health issue by reviewing some of the research in this area and discussing potential interventions.
