Traditional Chinese acupuncture may help relieve pain from arthritis of the knee. But so could "sham" acupuncture, in which needles are inserted shallowly and outside the traditional "meridian" points. The key, according to a new clinical trial of 455 patients plus 72 controls, seems to be the attitude of the acupuncturist. While there was no significant difference between real and sham acupuncture — both provided more pain relief than no treatment at all — a "positive" treatment style produced better results than a "neutral" style. When the acupuncturist (genuine or pretend) told arthritis patients, "I've had a lot of success with treating knee pain," subjects reported greater pain relief than when told "this may or may not work." Scientists said the findings suggest acupuncture's apparent benefits may be "partially mediated through placebo effects related to the behavior of the acupuncturist." — Arthritis Care & Research…

Could an occasional drink reduce your risk of rheumatoid arthritis? Following up on a recent Scandinavian study that found a reduction in rheumatoid arthritis (RA) risk among people who regularly consume alcohol, British researchers compared 873 RA patients with 1,004 healthy controls. Right from the start, as questionnaires gathered information on alcohol intake, a difference popped out: 36.7% of the RA patients said they never drank alcohol, versus just 10.9% among the healthy controls. Once the numbers were crunched, nondrinkers' relative risk of developing RA was 2.31 times greater than those who imbibed at all. And nondrinkers were at more than four times the relative risk of RA compared to those reporting drinking alcohol on more than 10 days a month. The scientists commented, "Further research is needed to confirm the results that we have demonstrated, and to investigate the mechanisms by which alcohol influences outcome in RA." — Rheumatology…

Even though glucosamine is widely used as a therapy for lower back pain, a new randomized controlled trial has found little difference between patients taking the popular supplement and those on a placebo. Norwegian researchers randomly split 250 people with chronic lower back pain and degenerative lumbar osteoarthritis into two groups: Half received 1,500mg of glucosamine daily for six months, while a control group got a placebo instead. Pain-related disability was measured using a standard questionnaire, and patients also rated their pain at rest and during activity. After six months and when re-tested after a year, there was no significant difference between the glucosamine group and those getting a placebo. In 2009, another randomized controlled trial similarly found glucosamine, as well as the supplement chondroitin, no more effective than a placebo in slowing cartilage damage from osteoarthritis, the most common form of arthritis. — JAMA…

Vitamin D's important role in bone health, already linked to protection against osteoporosis, may extend to joints and prevention of the most common form of arthritis. A new analysis of data on 1,104 older men in the Osteoporotic Fractures in Men Study reports that men with insufficient vitamin D levels were twice as likely to have hip osteoarthritis as those with normal vitamin D. Participants, who averaged almost 78 years old, had their blood levels of vitamin D measured and then, about 4.5 years later, underwent pelvic radiography to look for signs of arthritis in the hips. Men with insufficient vitamin D were also found to have slower walking speeds and greater hip pain. More research is needed on the relationship between vitamin D and arthritis, the investigators noted. One previous study failed to find a link between vitamin D levels and worsening of knee osteoarthritis, while a second study did find an association, especially in patients with decreased bone mineral density in the spine. — Arthritis & Rheumatism…

The tab for that jumbo cheeseburger, super-sized fries and extra-large soda comes to $147 billion. That is, figured nationally, the cost of obesity-related diseases, according to a new report by the Centers for Disease Control and Prevention (CDC)—totaling 9.1% of all US medical spending. The average obese person, the CDC study found, spends 40% more on healthcare—$1,429 a year—than someone of normal weight. Drug costs alone for an obese Medicare recipient total $600 more annually than for normal-weight beneficiaries. The CDC said more than 26% of all Americans are now considered obese, defined as a body-mass index (BMI) of 30 or higher. (A person 5-foot-5-inches tall, for example, would be obese at 180 pounds.) That obesity rate rose 37% between 1998 and 2006, leading to an 89% increase in spending on obesity-related health problems including heart disease, diabetes and arthritis. Dr. Thomas Frieden, CDC director, said, "It is critical that we take effective steps to contain and reduce the enormous burden of obesity on our nation."—CDC…

Sniffling and wheezing from allergies or asthma? Maybe you're not getting enough folate. New Johns Hopkins research has linked low levels of folate, a type of B vitamin found in leafy green vegetables and (as folic acid) in fortified grain products, to higher risk of allergic symptoms. In a study of 8,083 participants in a national health and nutrition survey, those with the lowest blood folate levels were 40% more likely to wheeze and 31% more likely to have allergenic reactions than those with the highest folate amounts. Researchers wrote, "These findings suggest that dietary folic acid and factors affecting its metabolism might play an important role in the development and perpetuation of allergy and asthma." Low intake of folate and its synthetic form, folic acid, found in supplements and fortified foods, has previously been associated with inflammatory diseases, such as rheumatoid arthritis.—Journal of Allergy & Clinical Immunology…

Men with higher intake of vitamin C from food and supplements appear less likely to develop gout, a painful form of arthritis. Gout is the most common type of inflammatory arthritis in men and is increasingly common. A study of 46,994 men over a 20-year span found that those with the highest total intake of vitamin C (1,500 milligrams daily or more) were 45% less likely to develop gout than those with the lowest intake. Overall, each 500-milligram increase in daily vitamin C was associated with a 17% reduction in gout risk. Vitamin C appears to reduce levels of uric acid in the blood, according to the researchers; a buildup of this naturally occurring compound can form crystal deposits in and around joints, leading to the pain, inflammation and swelling associated with gout.—Archives of Internal Medicine

Almost four in 10 American adults—and one in nine children—are using complementary or alternative medical treatments, up slightly from five years ago, according to a new government study. Back pain was the top reason for turning to alternative treatments, followed by neck and joint pain and arthritis; popular treatments included deep-breathing exercises, meditation and massage therapy. Overall, the most commonly used adult treatment was fish oil. The study was the first to ask about use of unconventional treatments by those under 18, who most commonly sought relief for back pain, colds, anxiety, stress and attention deficit hyperactivity disorder.—US Centers for Disease Control and Prevention…
