WEDNESDAY, April 18 (HealthDay News) — Long-term exposure to fine-particle air pollution may increase older adults’ risk of being hospitalized for lung and heart disease, stroke and diabetes, a new study says.
Harvard School of Public Health researchers compared air-quality data with hospital admission records on all Medicare patients aged 65 and older admitted to 3,000 New England hospitals between 2000 and 2006.

These particles — emitted by vehicles, power plants, wood-burning devices and some industrial processes — can lodge in the lungs and cause inflammation throughout the body. Read More
