No association between rheumatic inflammation and air pollution?

Contrary to previous studies, a new study in the United States said, there was no link between air pollution and rheumatoid arthritis.

Rheumatoid arthritis is a chronic disease that corrodes joints, deforms the body, increases the risk of heart attack by three times and increases the chance of getting some cancers.

Rheumatoid arthritis deforms the joints

Previous studies have shown a link between air pollution and the risk of developing rheumatoid arthritis.

However, a large-scale study led by Jaime Hart, a medical aide at Boston Women's Hospital, found no connection.

The team followed 111,425 women who worked as nurses across the United States, every two years, from 1976 to 2006. 858 people confirmed rheumatoid arthritis, according to reports published in Arthritis Care & Research.

The team estimates the extent to which subjects are exposed to polluted air, such as from traffic or energy plants.

They focus on outdoor air pollutants, including dust particles from soot, ingredients that form smog, such as nitrogen dioxide and sulfur dioxide.

Speaking on Reuters on March 14, the scientist Hart said the team was surprised to find no link between rheumatoid arthritis and the constituents of outdoor air pollution.
