New research has indicated that consumption of fructose-rich beverages, such as sugar-sweetened sodas and orange juice is associated with an increased risk of gout among women.
However their contribution to the risk of gout in the population is likely modest because of the low incidence rate among women, according to a study that will appear in the November 24 print edition of
JAMA. The study is being released early online to coincide with its presentation at the American College of Rheumatology annual scientific meeting.
Gout is a common and very painful inflammatory arthritis. "The increasing disease burden of gout in the United States over the last few decades (e.g., an annual incidence of 16/100,000 in 1977 vs. 42/100,000 in 1996) coincided with a substantial increase in soft drink and fructose consumption," the authors write. "Fructose-rich beverages such as sugar-sweetened soda and orange juice can increase serum uric acid levels and, thus, the risk of gout, but prospective data on the relationship are limited."
Hyon K. Choi, M.D., Dr.P.H., of the Boston University School of Medicine, and colleagues examined the relationship between intake of fructose-rich beverages and fructose and incidence of gout in a large group of women. The study consisted of data from the Nurses' Health Study, a U.S. prospective cohort study spanning 22 years (1984-2006). The researchers analyzed data from 78,906 women with no history of gout at the beginning of the study and who provided information on intake of beverages and fructose through validated food frequency questionnaires.
