Depression Rates Drop In Many Adult Age Groups

Depression Rates Drop In Many Adult Age GroupsA new study suggests the incidence of depression is decreasing among many older adults, although it may be that the decline is the result of more effective treatment or other factors.

University of Michigan Health System researchers discovered overall rates of depression in people over 50 are on the decline. Specifically, investigators discovered that between 1998 and 2008, rates of severe depression fell among the majority of older adults, especially the elderly.

The elderly have historically been a higher risk group for depression. However, late middle agers between ages 55-59 appeared to experience increased depression over the 10-year period.

The nationally representative study appears in the Journal of General Internal Medicine.

“Over that decade, we saw a significant decrease in depression among older adults, and we need further studies to explore whether this is the result of improved treatment,” said lead author Kara Zivin, Ph.D.

“Even with signs of progress, however, a significant percent of our population is still experiencing severe symptoms of depression, and we need to do more to ensure all of these groups have proper access to treatment.”

Late-life depression has been a major area of concern among health providers, with studies showing increased depression at a time when many face death of loved ones, isolation, medical problems or changes in economic status.

Surprisingly, the new study suggests improvements in this trend, with the most pronounced drop in depressive symptoms in people in the 80-84 age group.

Increases in depression rates were concentrated among people in late middle age between ages 55-59 – a group that hasn’t traditionally been focused on as an at-risk group.

“It’s unclear whether this shift is an indication of a sicker population not being treated adequately, a burden on people of that age at that particular time or something else, which is why we need to do more research to better understand these patterns,” Zivin said.

Researchers used data from the Health and Retirement Study, a nationally-representative sample of older Americans that is conducted by the U-M Institute for Social Research on behalf of the National Institute of Aging.

“We were pleased to see that there appears to be an overall improvement in depressive symptoms in the US, which is most likely related to better recognition and treatment. We are hopeful that our findings highlight the importance of depression diagnosis and treatment, and that we continue to make progress in developing better ways to systematically improve the outcomes of patients with depression,” said senior author Sandeep Vijan, M.D., M.S., associate professor of internal medicine at the U-M Medical School.
