Isolation is a major concern for older people. 

Having friends move away or die can often leave seniors with few people to talk to on a regular basis. 

And there's evidence that isolation leads to depression. 

The evidence is collected and amplified by a new survey that shows depressive symptoms increase as face-to-face contacts with other people decrease. 

Oregon Health & Science University's Dr. Alan Teo, an assistant professor of psychiatry, is the lead author of the study.

Many of society's efforts to fight hunger focus on children, to ensure they grow up healthy. 

There are specific programs to provide nutrition to children of needy families, but many older adults could also use assistance in keeping hunger at bay.
