MONDAY, June 30 (HealthDay News) -- The risk of rheumatoid arthritis is twice as high in women who had a heavy birth weight (more than 10 pounds) than those with an average birth weight (7 to 8.5 lbs), a new study finds.
Researchers at the Hospital for Special Surgery, New York City, analyzed data from more than 87,000 women who took part in the U.S. Nurses' Health Study between 1976 and 2002. The women were aged 30 to 55 at the start of the study.
