Men with knee osteoarthritis may want to avoid soft drinks packed with sugar. This is the Council of the researchers who have discovered that drinking sugary soda is associated with the progression of the disease in men.
No link was found in women in the study of more than 2,000 people with knee osteoarthritis.
"Our main discovery is that, in general, the most sugary men drink, the greater the risk that the osteoarthritis knee will worsen," says researcher Bing Lu, MD, DPH. Lu is an assistant professor of medicine at Harvard Medical School and BioStatistician associated in Hospital Brigham and Women in Boston.
If you are thinking it is because the calories in soda can contribute to being overweight or obese - a known risk factor for knee osteoarthritis - think again.
much to the surprise of the researchers, the link between osteoarthritis of the knee and sugary soft drinks could not be explained only by weight, Lu says.
"We are very careful [taken into account] weight in the statistical analysis. We control not only for the general categories of overweight and obesity, but also for patient-specific body mass indexes, or BMIs "He says.

When men were divided into obese and non-obese, the connection between sugary drinks and worse in the knee damage held true only in non-obese men.
This suggests that soft drinks independently aggravate knee osteoarthritis from wear in joints caused by transporting excess weight, Lu says.
in people with osteoarthritis, cartilage in an articulation wears in some areas. The function of cartilage is to reduce friction in joints and serve as a "damper". Cartilage wear leads to pain and other symptoms.
Almost one in 100 people have evidence of knee osteoarthritis on radiography. And almost 19% of women and 14% of men more than 45 years have joint pain, stiffness and other symptoms of knee osteoarthritis, according to a study of 2007.
In addition to obesity, Known risk factors include:
- More advanced age
- Lesion prior to knee
- Extreme stress to joints
The study was presented this week at the annual meeting of the American College of Rheumatology in Washington, DC
So, what is a man who likes soda to do?
"There is an easy answer. Just do not drink [sugary] soda," says Lu. He notes that some studies also associated refrigerants to heart disease.
Another specialist says it goes too far. "As with everything, enjoy refrigerant in moderation.If you are [a man with] osteoarthritis of the knee and is drinking a lot of soda, this can be a reason to contain back," says the American College of Rheumatology Spokesman Scott Zashin, MD. Zashin is a clinical teacher of internal medicine in the Rheumatology Division of the University of Texas Southwestern Medical School in Dallas.
The study does not cause cause and effect, zashin notes. As with any study presented at a medical meeting, it was not completely reviewed by experts. The findings need to be repeated before any recommendations to patients can be made, he says.
What is known is that in people with knee osteoarthritis, every overweight weight is 4 per pounds of dead weight on knee Johnin says. "So concentrate on your diet and overall weight, not a component."
The American Beverage Association (ABA), the Commercial Association that represents non-alcoholic beverages in the USA, assumed the issue with the conclusions.
in a statement, the flap writes: "The new results" of the authors "- as they call them - only a possible use of refrigerant consumption with osteoarthritis on knees, which they claim to be proven without More tests. Consequently, this presentation does not establish that drinking refrigerants cause any negative health results or even if they are linked to negative health results. "
The tab instruction continues:" As stated by NIMSD (as National institute of arthritis and musculoskeletal and skin disease), with overweight and obesity can affect global joint health. However, all calories count when it comes to overweight and obesity, and there is nothing unique about the calories contributed to Diet by soft drinks. "
Lu says certain ingredien ts in sugary soft drinks, including phosphoric acid, caffeine and ingredients for coloring and sweetening, can affect the absorption of calcium and SA bone construction uddish. But it continues to be studied.
Lu and colleagues reviewed the records of 2,149 men and women who participated in a large study of osteoarthritis. They were determined to have knee osteoarthritis by x-ray.
at the beginning of the study, all filled dietary questionnaires who asked how many soft drinks, not including drinks without sugar, they drank on average each week.
Every year for four years, the researchers traced their progression of osteoarthritis measuring the space between the joints. The more lost cartilage, the less space. BMI was also measured.
After taking into account BMI and other risk factors for knee osteoarthritis, men who drank five or more soft drinks with a week had double the narrowing of space set compared to men who did not drink soda sugary.
Financing for the study was provided by the national health institutes. Financing partners included Pfizer, Inc.; Novartis Pharmaceuticals Corporation; Merck research laboratories; and Glaxosmithkline. They all do anti-arthritis drugs.
These discoveries were presented at a medical conference. They should be considered preliminary, since they have not yet submitted to the "peer review" process, in which external experts examine the data before publication in a medical journal.
