People who have arthritis will know how difficult and painful it can make daily life. Many people associate arthritis with aging, but it’s a condition that affects both children and adults all over the world. Let’s take a look at some arthritis statistics to better understand what this chronic condition is, who it affects, how to prevent it, and how it can be treated. 

What is arthritis?

Arthritis, or joint disease, is inflammation of one or more of the joints, such as the knees, knuckles, wrists, or ankles. Arthritis starts as joint inflammation but can progress into joint pain, swelling, and stiffness. There are more than 100 different types of arthritis that someone can be diagnosed with, but the two most common types are rheumatoid arthritis and osteoarthritis.

Arthritis is typically diagnosed after a series of physical exams, blood tests, and X-rays. Doctors will look for physical symptoms of arthritis and then run tests to determine what kind of arthritis someone has. X-rays can diagnose osteoarthritis and check for abnormalities like bone spurs, while blood tests can check for antibodies that indicate other kinds of arthritis.

Causes of arthritis

According to SingleCare’s arthritis survey, 47% of respondents with arthritis believed that age was the cause of their arthritis, 45% believed family history was the cause of arthritis, and 31% believed a previous injury was the cause of arthritis.

Rheumatic diseases like arthritis are complex and can have numerous causes. It can be caused by autoimmune diseases, injuries, infections, normal wear and tear on joints, and genetics. 

“Most commonly, arthritis is seen in adults over age 65,” says Tom Biernacki, DPM, a board-certified foot and ankle surgeon and podiatrist in Berkley, Michigan. “It is more common in people who are very active, such as people who are on their feet all day at work. Other risk factors include people who are overweight and people who have less muscle mass compared to their body weight. Unfortunately, as we all get older, on average, we get heavier and our muscles get weaker. This will lead to increased wear and tear of cartilage and eventually bone-on-bone rubbing. This does eventually catch up to most people who develop enough risk factors.”

Arthritis prevention 

It may not be possible to prevent arthritis entirely, but there are some things you can do to reduce your chances of developing it. Exercising regularly is really important to help keep your muscles strong and your joints limber. This will also help prevent injuries. Maintaining healthy body weight is also important because this means there’s less weight putting pressure on weight-bearing joints. Almost 23% of overweight adults and 31% of adults with obesity reported being diagnosed with arthritis, according to the CDC. Other ways to help prevent arthritis include stretching regularly and getting routine check-ups to make sure your joints are staying healthy.

In SingleCare’s arthritis survey, 31% of respondents with arthritis reportedly used exercise to reduce arthritis pain, and 21% reportedly modified their diet or participated in a weight loss program.

Many organizations and institutes are dedicated to helping prevent arthritis and work hard to educate the general population about arthritis prevention. If you want to learn more about how to prevent arthritis check out the Arthritis Foundation, Arthritis National Research Foundation, or talk with your primary care physician. 

Treating arthritis

Even though arthritis can be painful, there are treatments available to help reduce pain, inflammation, and stiffness. A 2010 study found that 42% of people who received a combination of rheumatoid arthritis treatments achieved complete remission within two years of starting treatment. Up to 68% of those achieved “low disease activity.”

Medications are often used to treat arthritis because they can reduce chronic pain and inflammation. Painkillers and over-the-counter anti-inflammatory medications may help arthritis pain. Corticosteroids can suppress the immune system and reduce inflammation. For conditions such as rheumatoid arthritis or lupus, disease-modifying antirheumatic drugs (DMARDs) can stop the immune system from attacking healthy joints. Biologic response modifiers target protein molecules that are involved in the immune response and help reduce inflammation. 

In a SingleCare survey, we found that 52% of respondents with arthritis took analgesics (like Tylenol) and 46% took nonsteroidal anti-inflammatory drugs (such as ibuprofen and naproxen).

Inflammation can be well controlled with anti-inflammatories, but this is usually a supplement and not the main treatment,” says Dr. Biernacki. “This should function as an assistive treatment, and not the core treatment.” 

There are also numerous surgical and medical solutions on the horizon. There are new joint replacement surgeries that have proven to be very effective with high success rates and good durability. There are also injections such as platelet-rich plasma (PRP) or hyaluronic acid that treat arthritis, and new types of stem cell injections show promising results but aren’t currently considered to be a standard insurance coverage treatment. 

Arthritis questions and answers

What country has the most cases of arthritis?

One study indicates that the United States has the highest prevalence of arthritis, especially osteoarthritis.

What percent of the U.S. population has arthritis?

Twenty-three percent of U.S. adults have some form of arthritis. 

How many new cases of arthritis are there per year?

The prevalence of rheumatoid arthritis is predicted to rise by as much as 1% each year. 

What is the average age of getting arthritis?

The average age of getting arthritis varies depending on the type of arthritis, but most people develop the condition between the ages of 30 and 60. 

Why is arthritis more common in females?

Once women reach menopause, their estrogen levels drop and estrogen helps fight cartilage and joint inflammation. Women also have more flexible joints than men, which increases their risk of getting arthritis.
