Keep arthritis at bay by staying physically active and maintaining a healthy weight 

NEW YORK – What was once an easy run may feel tougher to complete. Or perhaps a challenging game of tennis might leave your hip or ankle sore for days.

Painful, stiff or swollen joints are a common complaint among older adults. And for many, they are the first sign of what may feel like an unavoidable diagnosis: arthritis.

In a recent survey of more than 2,200 people aged between 50 and 80 in the United States, 60 per cent said they had been told by a healthcare provider that they had some form of arthritis. And about three-quarters considered joint pain and arthritis a normal part of ageing.

But arthritis is not inevitable as people age, said Dr Kelli Dominick Allen, an exercise physiologist at the University of North Carolina School of Medicine.

“Sometimes, people will start to get aches and pains in their joints and not do anything about it because they think everyone gets arthritis as he or she gets older,” she said. “We shouldn’t think about arthritis as something that we just have to deal with passively.”

Arthritis is a catch-all term for the more than 100 kinds of inflammatory joint conditions, each of which can arise for different reasons. Many of those causes have little to do with age, she added.

One form of degenerative joint disease though, known as osteoarthritis, is somewhat more likely to occur as a person gets older, said Dr Wayne McCormick, a geriatrician at the University of Washington School of Medicine. “It’s basically just worn-out joints,” he said.

Osteoarthritis is most commonly seen among people older than 50, particularly women, Dr Allen said.

Scientists do not know why some people are more prone to joint inflammation and pain with age than others. But about 12 per cent of osteoarthritis cases are a result of joint injuries, such as meniscus or ligament tears, from when they were younger.

Arthritis is also more common among people who have a family history of the condition, or who have certain chronic conditions such as obesity, heart disease or diabetes.

Some people may find that their joint pain limits their activities as they age.

But others, whose X-rays may show significantly worn-out joints, may experience no pain, Dr McCormick said.

As a result, he added, “each person has to develop his own plan of how to stay healthy and functional with the help of his physician”.

For most people, Dr Allen said, preventing arthritis later in life should begin many years before it is a concern – by taking steps to prevent joint injuries during sports or exercise, and recovering properly when they occur.

For those who are not at risk of developing sports-related injuries, staying physically active and maintaining a healthy weight can help to prevent excessive wear and tear of your joints and to reduce pain if arthritis sets in later in life, she added.

In a 2015 review of 44 clinical trials, for instance, researchers found that participants who exercised regularly had reduced knee pain related to osteoarthritis and improved physical function and quality of life.

“It actually does help if you can do low-impact exercise, like a stationary bicycle where your knees, hips and joints aren’t receiving so much impact,” Dr McCormick said.

Strengthening muscles such as the quadriceps and hamstrings helps to support the joints, he added.

In addition to regular exercise, supportive knee or ankle braces, over-the-counter pain medications such as ibuprofen or acetaminophen, or steroid injections into a problematic joint can all help relieve joint pain to varying degrees, he said.

Not every option works for everyone, he added, so it is important to find what helps you to stay active.

Similarly, dietary supplements such as glucosamine and chondroitin sulfate – or herbal remedies such as boswellia (an herbal extract made from the bark of the boswellia tree) – may help relieve symptoms for some people. But there is not much scientific evidence to support their use, Dr Allen said.

“There have been a fair number of clinical trials, but mixed evidence on their effects,” she said.

Dr McCormick said that, in his experience, it’s “very unusual for these supplements to be harmful” so they could be worth trying – or stopping if they do not seem to help.

Ultimately, finding ways to live a pain-free, active and healthy lifestyle is the best way to reduce your risk of developing arthritis later in life, Dr Allen said.

Many of the actions that reduce the risk for other chronic conditions such as diabetes or heart disease are powerful tools for lowering age-related joint disease risk too, she added.

“Somebody who’s trying to maintain a healthy lifestyle will already be doing the things that are most important for reducing arthritis risk,” she said. NYTIMES
