Depression a Big Factor in Poor Health

Depression has a greater impact on overall health than arthritis, diabetes, angina, and asthma, but it all too often goes unrecognized and untreated, a report from the World Health Organization (WHO) suggests.

Based on interviews with almost 250,000 people living in 60 countries, WHO researchers found depression to be a greater predictor of poor health in patients with these chronic conditions than having one or more chronic medical conditions without depression.

People who had arthritis, diabetes, angina, or asthma were more likely to suffer from depression than people without these conditions.

And consistent across different countries and cultures, people with depression plus one or more of the chronic diseases included in the study had the worst overall health scores.

The findings, which appear in the Sept. 8 issue of The Lancet, illustrate the urgency of identifying and treating depression in patients with other chronic health problems and in the population as a whole, the WHO researchers conclude.

"We have to recognize that mental health is not a luxury. It is a necessity for good overall health," researcher Somnath Chatterji, MD, tells WebMD.

"Health care providers are so focused on the physical health of their patients that they often miss the signs of depression. But treating depression can have a big impact on overall health."
