Study: heavy traffic may hold link in depression

Posted: Updated:
ESSEN, Germany (NBC) -

There's now some evidence that living near a busy, noisy road may be linked to depression.

In a study taking place at University Hospital Essen in Germany, researchers analyzed data on more than 3,000 adults who were followed for about five years.

Those who lived in areas with a lot of traffic had about a 25% increased risk for developing depression. This group was also more likely to live in an impoverished area, smoke and be unemployed, however.

The study, which does not prove heavy traffic causes depression -- but instead that it may be one factor, is published in the journal Environmental Health Perspectives.
